JP6025077B2 - Shinkawakura style water system and deadline - Google Patents

Description

  The present invention succeeds Kawakura, which has been unrivaled for 300 years in river and flood control works, while succeeding in its style, through the improvement from the traditional manual construction method to the mechanized construction method. It relates to effective water control and recycling as a deadline structure.

“Kawakura”, also known as “Sacred beef”, has existed for about three hundred years from the time of Shingen Takeda to the Edo period to the Meiji period to the first half of the Showa period and has functioned as a very effective and powerful water system and deadline construction method. It was. Triangular pyramid simple and stable structure. By continuously installing objects as a group on the inner side of the levee, sediment is deposited at the base of the levee during floods, and the turbulent water flow does not directly hit the levee, protecting the levee from breaking Give me. Sand on the rapid stream side near the center of the river has flowed downstream to secure the river volume and has been used in deadlines. Since the 1950s, seawalls and irregular blocks have gradually been replaced, and the water control method and water control philosophy itself have been abolished. In recent years, criticism has increased from the viewpoint of deterioration of water quality due to concrete revetment work, conservation of river landscape and ecological environment, and water control structures using old construction methods have begun to attract attention again.
Conventional Kawakura uses thick and heavy wood logs, combined with the structure of a palm-shaped triangular pyramid, assembled and constructed with annealed iron wires, staples, snails, etc. It was a way of filling a lot of stones and placing them on the structure. Almost all of these tasks depended solely on direct human effort.
In addition, as a prior art of waterworks constructed in a form that protrudes from the land side into the water flow, a masonry skeleton that is built up so that a block with a wall body standing on a flat bottom plate is covered from above As an embedding block for river structures that embed the whole inside the masonry and a construction method of river structures (see Patent Document 1), sandbags are installed in a T-shaped bank shape, Water that is constructed by installing a net-like bag material so that it surrounds its surroundings, and uses construction by-products such as stones, concrete shells of demolished structures, excavated earth and sand, etc. A construction and a construction method thereof (see Patent Document 2) are known.

  Japanese Patent Laid-Open No. 10-195840   JP 2010-180637 A

In the present era, wood logs are not easy to obtain themselves, and are more difficult and expensive in large quantities. In the event of a disaster, it is virtually impossible to obtain a large amount of the product at a time when an emergency is required. Assembling the gabions and filling the stone block itself is predicated on direct human power, and is completely unsuitable for the stone filling work using heavy machinery. It was also clear that the decline of the philosophy of “water system” itself was largely due to the difficulty of standardizing installation and design, as well as making it difficult to understand the direct effect of the water system on preventing river erosion. It was. The industrial mass production of necessary materials and the mechanization in construction are made possible, and the excellent old construction method that has been tried out is revived by combining with modern technology. We must respond to the demands of the times in disaster prevention and water systems.
The prior art shown in Document 1 is that the construction of rock constructions in floods is not so large in view of the current situation when it is difficult to secure large rocks used in flood control constructions. Paying attention to the fact that the structure is more likely to collapse due to the lack of movement and stability of the rocks due to water flow, and the inverted T-shaped block material is buried inside the structure as a skeleton. Although it is a method to reinforce, "consideration" shown in the structural features such as through holes, notches and legs of the block is to secure the fish nest space and prevent stagnant water (dead water) that tends to occur on the downstream side of the structure. In particular, it is appealing as a “multi-natural” river construction method that presumes gentle daily water flow rather than dealing with a situation where the danger of flooding is imminent for a long time. It can be said that. Or, in the case of a rather large river, considering that the riverbank or riverbed is inside the riverbank where the water control works are constructed, and that fish nests and dead water are not likely to be a problem during normal times. However, the most important function of the water system, which plays a role in preventing river bank breakage caused by turbulent flow, must be evaluated as a rather halfway method. The problem of the deterioration and destruction of the ecological environment is that the riverbank itself should be built as straight as possible and with as much concrete as possible, and as soon as possible in the sea instead of “live out” the water. The philosophy that has been brought about by the philosophy shift of “throw away” and has been proved to be a great achievement for hundreds of years. If we think that it was the result of Japan's era of thinking that was abandoned at a stroke during the year, we will fully consider the “limits” of the functions that water systems can handle when confronting the historical challenge of “natural river development” After recognizing it, it should be possible to fully realize the waterworks.
The prior art shown in Document 2 is that, in the conventional water control construction, especially when using rough slag, it is difficult to secure the rough slag itself as a material and the poor workability when using slag, and the use of heavy machinery Focusing on the fact that it cannot be made, and instead of using natural blocks that are prone to deterioration due to natural materials, the problem is the great danger of “Kawadori Senbori” when using concrete blocks that can be used in heavy machinery. A “sandbag bag” filled with concrete shells, earth and sand, stones, etc. “easy to procure” is laid in a large T shape, and stones, concrete shells, etc., excluding soil that tends to be washed away, are laid around the outer periphery. It is a solution that is constructed so as to be surrounded by “net-shaped bag material” packed inside. It will be more durable than rough ridges, and will surely be superior to block materials in the flexibility to refill the riverbed scoured part. However, this is also the same as in Reference 1, where the assumed “situation” is that river flooding and flood damage are imminent, rather than the amount of water and the intensity of the flow. I can only assume that the situation is such that it is not easily swept away by the amount of material. The rivers unique to the Japanese archipelago that are completely different from the continent are that countless large rocks of several meters swaying like the leaves of the earth with a roaring sound that shakes the earth, and then raging just beyond the riverbank. The transformation from peacetime to emergency progresses drastically at a stretch. It must be said that it is a “solution” that cannot be considered as a countermeasure for those who have actually seen or experienced such a “situation”. Regardless of whether the sandbag or net-shaped bag material is a T-shaped or other type, in a structure that is simply laid on the inner side of the riverbank, each “net-shaped bag material” is more than a leaf. It would not be possible, and the role of the “Guards”, which protects the critical erosion of riverbanks from muddy flow, would not be able to be fulfilled.
The present invention is intended to solve the above problems.

Means to achieve the challenge

General structural carbon steel (hereinafter, abbreviated as steel pipe) and Kawakura body constructed substantially triangular pyramid shape in combination, boulders packed bag installed on the bottom side of the main body (a portion corresponding to the floor), rocks It is composed of a cobblestone bag hanging tool for holding the bag mouth fully open when stuffing , and a bundling wire for bundling a full cobblestone bag. It is a Shinkawakura style water system and deadline construction that is mass-produced industrially as a set product and is permanently stored, and completes construction construction in a very short time using heavy machinery.
The Kawakura body uses steel pipe material instead of conventional wood logs. The diameter of the steel pipe is mainly assumed to be 60.5 mm or 101.6 mm, which is light and easy to assemble, and inherits the traditional style of gassho-gumi that has confirmed its firm effect. There are generally 21 steel pipes per Kawakura, except for special cases.
Will be described below Kawakura whether that built the body how the by these steel pipes. The length and diameter of the steel pipe can vary depending on the river scale and the special conditions of the installation location within the range that does not disrupt the balance that establishes Kawakura's traditional style, but the following is calculated from experience. -The most widely applicable model figure.
As Niodachi confronting the upstream direction coming water, 3.7 m are bundled fixed freely clamping the two steel pipe length at the position of the upper end front, rising Tachinobo previous twofold formed a rafter, the root position near the two front rafter foot digs into the ground triangular pyramid flared, steel pipe 3.2m length bridged coupled to the left and right, to fix the base portion of the front twofold relative lateral Ru Thea provided with a sand pay of place to stabilize. One end of a 4.8m steel pipe rests on the forehead of the head of the front joint, that is, the front joint composed of two front joint head pieces, and the other end descends diagonally downward and lands on the front. It has a ridge that serves as a backbone that supports the back of the palm. From the outside of the right and left front butt seam leg before Gassho,其s end of the steel pipe of 4.6m is Ri mounting on the sand payments, the other end Shin the Activity to the rear, the ridge of the rear end together with the horizontal height bound in the form of sandwich, Ru results in providing a digit at which the shape extending open to the fork to the front from the rear tare. Thus, the previous twofold and ridge coupled rigidly have you up and down to obtain a strong basic skeleton to support the overall stability.
In almost intermediate point before and after the building, bifurcated, which is twofold set by two steel pipes of 2.7 m, Ru tare provided Gassho After standing upright in a manner that placed sandwiching the ridge. Single steel pipe 3.2m Ru Tei coupled in two contacts upright the central rear wings front and sand payment projecting from the front rafter head forward before Gassho forms a front vertical. The front end of the digit being combined with the previous twofold, namely the rear side of the front butt seam, Ru tare provided a beam before coupled to bridge the steel pipe 3.6m on the left and right digit. At the same substantially similar, before side of the rear butt seam and coupled to that rear central portion-digit Gassho, Ru tare provided a beam after it has been coupled to bridge the steel pipe 3.0 m. The steel pipe of a total of 10 pieces of 2.4m to the front bridge at a certain distance the beam and rear beam, front right and left two on each outer side of twofold, two sandwiched before Gassho piece, the middle It is connected to the front beam in such a way that three each are arranged on the left and right of the front, and extends in parallel rearward from there, and is sandwiched between three each on the left and right outer sides of the rear joint and two rear joint pieces. coupled to the rear beam in the form of this is provided, Ru tare provided made insole made of ten in that way.
In the construction work so far, the steel pipes used for front joints, sand removal, ridges, girders, rear joints, foreheads, beams and laying are light, strong and easy to handle, where the steel pipes intersect each other. All are instantly clamped and fixed with a free clamp, and the worker proceeds with speedy assembly with one spanner from start to finish, and the construction of the main body is completed in about 15 minutes.
In the Kawakura body formed in this way as a whole, two cobblestone bags equivalent to about 1.5t are installed adjacent to each other on a floor that can be called a floor having gaps at regular intervals. . Cobblestone sachets are filled with large cobblestones, rocks, miscellaneous stones, large concrete block shells, etc. that are left on the site, but it is necessary to manually fill up the old gabion. Unlike the work that spent labor and time, during the stuffing operation, the bag mouth is hung on the hook of the cobblestone bag hanging tool, and the cobblestone bag hanging tool is lifted with a crane to keep the bag mouth wide open. The other heavy machine is packed at once. The cobblestone sachet has a strong plastic resin mesh that will not break even if such a large and crushed rock mass is stuffed into a random piece of material, and is premised on mass production by machines. The filled cobblestone bag is removed from the hook of the cobblestone bag hanging tool and the bag mouth is tied with a tie wire. When this is installed in the Kawakura body, it is lifted with heavy machinery, installed two adjacent on the floor, and the bag body parts are joined together with one binding wire, and each bag The mouth bundling part is hooked and fixed to the front joint head with a bundling wire.
Cobblestone packed bag hanging utensil, a pair saw together the hanging hook frame into four steel pipe quadrilateral, in two frame sides which mutually pair of opposed hanging hanging frame,其s across corners, ie another is fixed to the intersection of the sets of opposing each other frame side, and hanging hook rope that hung suspended to the crane forms a semicircular loop, provided on the lower side of the four frame sides, cobblestone packed bag It consists of multiple hooks that hang around the bag mouth.
The binding wire has a handle type adjustment mechanism that quickly tightens and adjusts the length.
Thus, there is no “face” anywhere on the floor, wall, or roof, so the Kawakura body formed as a so-called framed structure does not accept the shock pressure that is unimaginable of sudden turbulent flow even at the “face”. While flowing, weighs about 2 tons of cobblestone bags, and the whole is firmly laid on the ground contact surface of the riverbed, and the lower ends of the steel pipes that form the front, front, rear, and ridges bite into the ground, like timber logs No skate on the riverbed or stones, and it does not easily float due to the buoyancy of the water, and continues to stand against the violence of the attacking water current, and the final destructive action on the riverbank It prevents.
At that time, the individual boulders not Ika been kidnapped torrent is integrated as stone 1 to about 1.5t by boulders packed bag, it is bundled in one and another boulders packed bag, further cobblestone Each sachet is hung on the two palms of the Kawakura main body, never being separated from the Kawakura main body, and continues to play the role of the weight of the Kawakura main body. This is a natural consequence of the dialectic inherent in the Kawakura style itself, in which the entire cobblestone is protected from being washed away by the Kawakura body, and other water systems and deadlines never have any form. It is power that cannot be done.
It is usually necessary for the new Kawakura style to be able to construct and install the required number of bases in a short time continuously, evenly or unevenly along the inside of the area where rivers and rivers are in danger The material must be kept in stock enough, and there should be no circumstances such as difficulty in obtaining the material in the event of an emergency, and all the materials used are always guaranteed in large quantities by mass production. In addition, it must be carried immediately to the construction installation site at any time, and work must be started without changing the time to complete the construction in a short time. To realize this mission without delay, "21 steel pipes with 60.5mm or 101.6mm diameter, two cobblestone bags and binding wires required for them, and a cobblestone bag hanging tool for heavy machinery use, spanner" As a set, a sufficient amount is stored in a fixed place in a form divided into sets.
In addition, as a substitute for a cobblestone sack, a concrete block equivalent to about 1 t is prepared for mass production and used in combination with a total of 2 to 5 t in accordance with the special conditions of the installation location. In that case, multiple concrete blocks installed on the floor are stacked in two lower tiers, two middle tiers, and one upper tier, stacked with hanging brackets attached to each concrete block, and penetrated vertically. The insertion holes of the corresponding length are inserted into the insertion holes provided at the two left and right positions, and are firmly connected and integrated, and the bottom of the bottom concrete block has a facing steel pipe There is a groove to fit in, and all can be constructed and installed by heavy machinery, and the same effect can be obtained without being inferior to a cobblestone bag without fear of being washed away.
This is a Shinkawakura style water system and deadline construction using general structural carbon steel pipes.

Effect of the invention

(B) Since steel pipes are used instead of the traditional wood logs, which are the main elements of Kawakura, there is no fear of material procurement, and they are thin, strong and lightweight, so handling in the work is extremely easy and quick work progress is guaranteed. Is done.
(B) Logs tend to float in the water stream, and the grounding part slides on stones such as roots, but the grounding part of the steel pipe bites in reverse.
(C) The work of fixing and binding logs together is to drive an annealed iron wire into a log, whip and tighten the struck iron wire with a “sino”, adjust with a hammer and stop with a staple, and tighten so that it does not loosen Whilst whilst cleverly using the staples and small piles etc. of the steple to fix the assembly by winding it several times while keeping the iron wire loose, all because it is directly manpower, so pliers, cutters, It required a lot of tools such as a hammer, a saw, a hanging arrow, and a manila rope, but in Shinkawakura using a steel pipe, all the manual work can be quickly assembled with a single spanner.
(D) Spending a tremendous amount of time and labor-Replacing gabions that have been assembled with skilled skills, plastic cobblestone sachets that can be mass-produced mechanically, and standardized concrete blocks Therefore, it is possible to quickly and in advance urgently construct a water control group of a necessary scale according to a plan calculated in advance by using the latest heavy machinery for the majority of construction on the premise of industrial mass production.
(E) Since the materials are cheap and light, even in the case of large rivers, a constant storage location that does not require much space is provided for each work area, ensuring a sufficient amount of materials at all times, and sudden emergency situations In addition, you can prepare everything.
(F) Since the type and amount of materials per unit of Shinkawakura are determined, they are stored separately for each set, and are delivered in the form of holding the set. Unloading can be performed while the work can be started.
(G) Even if other water works are formed into L-shaped or T-shaped structures using sandbags, stones, or concrete blocks, the river revetment embankment will be in danger of facing an endangered death There is no way to resist the turbulent flow, and it is highly likely that the structure itself will be washed away easily and the structure itself will be washed away. This is the first time to close up the value that should be done, and the new hydration and deadline construction as a concrete structure has been realized through the present invention, and can contribute to the future direction of river disaster management.

Embodiments of the present invention will be described below.
Kawakura main body (1) constructed by combining general structural carbon steel pipes into a roughly triangular pyramid shape, cobblestone bag (2) installed on the bottom side (location corresponding to the floor) of this main body, and stone filling cobblestone packed bag hanging tool for keeping lifted to hold the state of being opened to fill the bag mouth when the (4), boulders packed bag becomes full (2) binding wire for tying the (3) is composed of, these various materials is standing storage is produced industrially on a large scale as a set of set products, in Shinkawa warehouse style water system, the deadline Engineering of place to complete the construction built in a very short time using the heavy equipment is there.
The Kawakura body (1) uses steel pipe material instead of conventional wood logs. The diameter of the steel pipe is mainly assumed to be 60.5 mm or 101.6 mm, which is light and easy to assemble, and inherits the traditional style of gassho-gumi that has confirmed its firm effect. There are generally 21 steel pipes per Kawakura, except for special cases.
Hereinafter will be described how that is built by these steel Kawakura body (1) how the out of order. The length and diameter of the steel pipe can vary depending on the river scale and the special conditions of the installation location within the range that does not disrupt the balance that establishes Kawakura's traditional style, but the following is calculated from experience. It should be understood that this is the most widely applicable model value.
Standing in the water flow direction (S), two steel pipes with a length of 3.7m are crossed in front of the upper end to form a joint with two steel pipes (5a, 5b). ) rising is Tachinobo, triangular pyramid before firmly bite into the ground flared twofold legs (6a, a position risen several tens cm from the base of 6b), steel pipe 3.2m length bridged coupled to the left and right, before rafter (5) the root portion of the fixed against lateral Ru tare provided sand拂doctor (7) where stabilize. One end of a 4.8m steel pipe is placed on the front joint palm head (8) consisting of the front joint palm (5), ie, the front joint palm head (8a) consisting of two front joint palm pieces (8a, 8b). landed down down down, Ru tare provided before rafter from the downstream side (5) building at which the spine support powerful bracing the back part (9). From the left and right outsides of the two jointed legs (6a, 6b) of the front joint (5), place one end of a 4.6m steel pipe on the sandbag (7) and extend the other end to the rear. bonded in a manner sandwiching the horizontal height ridge of the rear end, Ru consequently provided digits at which a shape extending opening bifurcated forward from the rear (10) tare. As a result, the front joint (5) and the ridge (9) are tightly coupled with each other up and down to obtain a solid basic skeleton that supports the overall stability.
Two rear joint pieces (11a, 11b) standing upright in the form of sandwiching the ridge (9) on a bifurcated joint with two 2.7m steel pipes at approximately the middle point before and after the ridge (9) Ru tare rafter (11) provided after the consist. Standing up a single 3.2m steel pipe joined at two points of contact between the front end of the front joint (5) and the ridge (9) projecting forward from the joint head (8) and the center rear side of the sandbag (7) by, Ru Thea provided before falling (12). The front end of the girder (10) attached front palms together and (5), i.e. the rear side of the front butt seam (5), coupled to bridge the steel pipe 3.6m on the left and right digit (10) before Ru Thea provided with a beam (13). At the same substantially similar, the rear butt seam (11) central portion of the digits (10) which joins the, i.e. the rear butt seam (11) in front of the beam after it has been coupled to bridge the steel pipe 3.0 m (14) Ru the provided Thea. A total of 10 2.4m steel pipes bridging the front beam (13) and the rear beam (14) at regular intervals are connected to the left and right front joint pieces (5a, 5b) of the front joint (5). The outer beam is sandwiched between two front joint pieces (5a, 5b) and joined to the front beam (13) in such a way that three each are arranged on the left and right of the center front stand (12). There is a rear beam (14) which extends in parallel to the rear from there and three are arranged on the left and right outer sides of the rear palm (11), and four are sandwiched between the rear palm pieces (11a, 11b). Yes bind to, and has a made insole consisting of ten in that way.
In the construction work process so far, front joint (5), sand crawling (7), building (9), girder (10), rear joint (11), front standing (12), front beam (13), rear The steel pipes used for the beam (14) and laying (15) are light, strong and easy to handle, and wherever the steel pipes cross each other , they are instantly clamped and fixed by the universal clamp (16). Assembling speedily one after another with one spanner from start to finish, the construction of the Kawakura body (1) is completed in about 15 minutes.
In the Kawakura body (1) formed in this way as a whole, a cobblestone bag (2a, equivalent to about 1.5 t) is formed on the floor (15) which should be called a floor having gaps at regular intervals. 2b) are installed adjacent to each other. The cobblestone bag (2) is filled with large cobblestones, rocks, miscellaneous stones, large concrete block shells, etc. that are left on the site, but it is hand-worked until it becomes full of old gabions Unlike the work that took a lot of labor and time, the bag mouth was hung on the hook (19) of the cobblestone bag hanging tool (4) and the cobblestone bag hanging tool (4) was moved by a crane. The bag is stuffed at once with the other heavy machine, while keeping the bag opening wide by lifting. The cobblestone bag (2) has a strong plastic resin mesh that will not break even if such a large and crushed rock mass is stuffed into random pieces, and presupposes mass production by machines. The filled cobblestone bag (2) is removed from the hook (19) of the cobblestone bag hanging tool (4), and the bag mouth is bound with a binding wire (3). When this is installed in the Kawakura body (1), it is lifted with heavy machinery and installed two adjacent on the floor (15), and the bag body is integrated with each other with one binding wire (3). Furthermore, each bag mouth binding part is fastened and fixed to the front joint head (8) by the binding wire (3), and the binding wire (3) is also rotated and fixed to the rear joint.
Cobblestone packed bag hanging tool (4) is Yes forms four steel pipe hanging suspended in partnership to quadrilateral frame (17), in two frame sides which mutually pair of opposed hanging hook frame (17) , Fixed at the corners of each end, that is, at the intersection with another set of opposing frame sides, and provided with a hanging rope (18) that hangs on a crane in a semicircular loop shape, the lower side of the four frame sides, Ru其s plurality tare hook (19) hooking the bag mouth of cobble packed bag (2).
The binding wire (3) has a handle type adjustment mechanism (20) that quickly tightens and adjusts the length.
Thus, there is no “face” anywhere on the floor, wall, or roof, and the so-called Kawakura body (1) formed as a so-called skeleton-like structure has an impact pressure that is beyond the imagination of sudden muddy flow. While catching without catching, the cobblestone bag (2) is about 2 tons in weight, and the whole is firmly laid on the ground contact surface of the riverbed. Front joint (5), front standing (12), rear joint (11), ridge ( 9) The bottom end of each steel pipe pipe bites into the ground, does not slide on the riverbed or stone like timber logs, and does not easily float due to the buoyancy of water, Keep standing and standing up against the shore bank to prevent the final destructive action on the riverbank.
At that time, each cobblestone is not exposed to the torrent, it is integrated by a cobblestone bag (2a) like a rock of about 1.5t, and it is one with another cobblestone bag (2a). In each cobblestone bag (2), it is hung on the two front joint head pieces (8a, 8b) of the Kawakura body (1) and never pulled away from the Kawakura body (1). 1) Continued to play the role of the cobblestone, the back and forth joint legs (6a, 6b, 6c, 6d) of the Kawakura main body (1) and the rear end of the ridge (9) brought a firm strut to the ground, and eventually the entire boulder Is the natural consequence of the dialectic inherent in the Kawakura style itself, which is protected from being washed away by the Kawakura body (1), and is a force that other water works can never have.
It is usually necessary for the new Kawakura style to be able to construct and install the required number of bases in a short time continuously, evenly or unevenly along the inside of the area where rivers and rivers are in danger The material must be kept in stock enough, and there should be no circumstances such as difficulty in obtaining the material in the event of an emergency, and all the materials used are always guaranteed in large quantities by mass production. In addition, it must be carried immediately to the construction installation site at any time, and work must be started without changing the time to complete the construction in a short time. To realize this mission without delay, "21 steel pipes with 60.5mm or 101.6mm diameter, 2 cobblestone bags and binding wires required for them, and a tool for lifting cobblestone bags for heavy machinery use, spanner" As a set, a sufficient amount is stored in a fixed place in a form divided into sets.
In addition, as a substitute for the cobblestone bag (2), a concrete block (21) corresponding to about 1 t is prepared for mass production, and combined with a total of 2 to 5 t according to the special conditions of the installation location. In that case, a plurality of concrete blocks (21) installed on the floor (15) are stacked in two lower stages, two middle stages, and one upper stage and attached to each concrete block (21a, 21b, 21c). Are inserted into the insertion holes (23) provided in two places on the left and right sides. The insertion boats (24) of the corresponding length are inserted into the insertion holes (23). In addition, the bottom of the bottom concrete block (21a) is provided with a groove that fits into the facing steel pipe and can be installed by heavy machinery. The same effect can be obtained with no fear of loss.
The present invention is configured as described above, and a specific embodiment thereof will be described below with reference to the drawings.
In order to be able to set up a new Kawakura-style structure at the speed of a moment in an urgent situation where the river bank embarrassed, where the danger of a break could be felt, the materials necessary for emergencies are usually determined in advance during normal times. Stock must be stored in a well-stocked place.
Light and durable pipes and general structural carbon steel pipes that are the building materials of Kawakura's main body (1) are stored in order in a storage warehouse, and are transported to the site when needed to be unloaded. The operator uses a single wrench tool to fix the steel pipe one after another with the universal clamp (16) and completes the assembly in about 15 minutes per unit. The Kawakura body (1) is quickly installed with a crane as shown in FIG.
The cobblestone bag (2) equivalent to about 1.5t, which is placed and fixed on the Kawakura body (1), is usually checked by checking the remaining storage during normal times, using heavy equipment in the manner shown in Fig. 9. It is made by stuffing work, and the bag mouth is tied up with the binding wire (3). A concrete block (21) equivalent to about 1 ton used together with a cobblestone bag (2) or as a substitute for it is ordered from the manufacturing factory at any time by checking the remaining amount of storage, and can be mass-produced mechanically in a short period of time. Is possible. These heavy materials are both replenished and stored as shown in FIG. 10 at the same location as the steel pipe material in the form shown in FIG. As soon as it is judged that an emergency is imminent, they are loaded into a truck in a short time with heavy equipment, rushed to a designated place, and quickly unloaded with a heavy equipment crane on the pre-installed Kawakura body (1). Installed. The cobblestone sack (2) installed in the Kawakura body (1) has its bag body united together by a binding wire (3), and each bag mouth binding unit is connected by a binding wire (3). It is hung on the joint head (8) and is also fixed by turning to the rear joint (11).
Even when using the concrete block (21) as a substitute for the cobblestone bag (2), all loading and unloading operations are performed promptly by heavy machinery and cranes. The concrete block (21), which is lowered onto the Kawakura body (1) and stacked in three steps, is penetrated up and down by the plug-in boat (24) and firmly joined together, and the bottom of the bottom step is laid A groove that fits into the surface of the steel pipe of (15) is designed, and the weight of several tons is firmly integrated with the Kawakura body (1), so it is destructive to the riverbank In response to the turbulent flow that attacks as a violent violence, they stand in a position to face the torrent at a point just before that. The unique structure of this Kawakura body (1)-that is, it is weak against buoyancy like a large wood, and in contrast to the slippery nature of the installation surface; Because it is a structure in which the main body and the heavy stone stand up against each other in a few tons of heavy stones, and they stand against each other in the direction of the torrent, Damage can be limited to minor injuries.
Here, in spite of the tradition of hundreds of years, the great flood control and philosophy that was once abandoned in the changing trend of the times is combined with modern mass production technology and machine production. It has great power as a Kawakura style water system and deadline, and is expected to contribute greatly to future river administration.
