Description

  The present invention relates to a cleaning device that drops deposits accumulated on a long surface to be cleaned extending along a horizontal plane from the surface to be cleaned, and a cleaning method using the cleaning device.

The excavation work when constructing concrete structures such as tunnels and roads in the basement is done by forming a retaining wall in the ground and excavating the inside of the retaining wall with a backhoe or other excavating machine. Install cut beams (support works) between the retaining walls. Then, a concrete structure is constructed in the underground after excavation and then backfilled to construct a tunnel such as a road, a railway, a waterway, or an underground space.
In the excavation work, when the excavated earth and sand are transported from the basement to the ground, the upper surface of the upper flange of the H-shaped steel such as a cut beam that constitutes a long surface extending along the horizontal plane ( The outer surface) and the upper surface of the lower flange of the H-shaped steel such as a cut beam that forms a long surface extending along the horizontal plane (the inner surface continuous with the H-shaped steel web) spills and accumulates. .
If the sediment is left on the upper surface of the flange, which is a long surface extending along the horizontal plane such as a cut beam, if the soil falls downward from the upper surface of the flange, There is a possibility that it may collide with a worker who is working on the side, and there is a possibility that earth and sand may be mixed into the concrete structure under construction and affect the quality of the concrete structure.
Therefore, conventionally, the sediment as sediment deposited on a long surface (surface to be cleaned) extending along a horizontal surface such as a beam is manually swept away using, for example, a long handle or high pressure water. It was made to eliminate by the method of removing using a washing machine.
In addition, by covering the cutting beam with a curing member, a method for preventing sediment from accumulating on the upper surface (surface to be cleaned) of the flange, which is a long surface extending along the horizontal surface of the cutting beam, etc. Is also known (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 5-25827

However, in the method of manually sweeping the surface to be cleaned with a long handle, a fall prevention fence (FIG. 6; fall prevention fence 81 shown in FIG. (See below), it is dangerous because it may fall into the basement of the opening when it is leaned on the opening side, and it cannot be removed efficiently and cleanly due to human power. There was a problem.
Moreover, in the method of removing the sediment deposited on the surface to be cleaned using a high-pressure water washing machine, the moisture content of the sediment increases, so that there is a possibility that it cannot be accepted at the place where the construction residual soil is received.
In addition, in each of these methods, when the size of the opening is large, it is difficult to remove the earth and sand accumulated on the surface of the flange located on the center side of the opening, and it is difficult to remove the earth and sand. there were.
Moreover, in the method of patent document 1, the mounting | wearing operation | work for covering the whole long cut beam etc. with the member for curing is dangerous. In particular, in the excavation work for deep excavation, the depth from the beam to the basement is deep, and it is dangerous to attach the curing member to the beam at a high place as viewed from the basement. In addition, when the curing member mounted so as to cover the entire cutting beam or the like is later removed from the cutting beam or the like, this removal operation is also dangerous.

If the soil is deposited on the upper cleaning target surface 4 and the lower cleaning target surface 5 and left as it is, the soil collides with an operator working on the underground side when the soil falls downward. It is possible and dangerous. Moreover, there is a possibility that earth and sand may be mixed into a concrete structure built underground to affect the quality of the concrete structure. For this reason, it is necessary to regularly remove the sediment deposited on the upper cleaning target surface 4 and the lower cleaning target surface 5 of the above-described beam 2 or lining girder 3.

As shown in FIG. 1, the cleaning device 1 is pulled by a pulling rope 6 (see FIG. 6; see FIG. 7) and can move while sliding on the long upper surface 4 to be cleaned along the long direction. And a compressed air supply unit 60 configured to supply compressed air to the compressed air injection unit 50 of the movable body 10.
The moving body 10 is configured to include a base 20, a base drop prevention unit 30, a prior earth discharging means 40, and a compressed air injection unit 50.
In the present specification, as illustrated in FIG. 1, the front side is the front and the rear side is the rear, based on the moving direction F of the moving body 10 that moves on the upper cleaning target surface 4 along the longitudinal direction. The upper and lower sides are defined as upper and lower, and the left side when the front of the moving direction F is viewed from the rear of the moving direction F is defined as left and the right side is defined as right.

As shown in FIG. 1; FIG. 2, the base 20 extends on the upper cleaning target surface 4 in a direction intersecting the longitudinal direction of the upper cleaning target surface 4, and the left and right side edges 4a of the upper cleaning target surface 4; For example, it is formed by H-section steel arranged so as to straddle between 4a.
The base 20 is pulled in a state in which the lower surface (outer surface) 22 of the lower flange 21 is in surface contact with the upper cleaning target surface 4, thereby moving on the upper cleaning target surface 4 along the longitudinal direction in the moving direction F. It is configured to be movable while sliding.
A through-hole 67 for passing the tow rope 6 is formed on the left and right sides of the H-shaped steel web 24 forming the base portion 20. A locking portion 68 such as a tool is formed, and the locking portion 68 is locked to the rear surface of the web 24 so that the work can be performed from the front side in the moving direction F of the moving body 10 as shown in FIGS. The person 8 pulls the tow rope 6 so that the moving body 10 can be moved in the moving direction F while sliding on the upper surface 4 to be cleaned.

As shown in FIG. 1; FIG. 2; FIG. 5, the base fall prevention part 30 extends from the base part 20 so as to face the left and right side edges 4a; 4a along the longitudinal direction of the upper surface 4 to be cleaned. Are provided in pairs. For example, the pair of base fall prevention portions 30; 30 are the left and right sides of the lower flange 21 of the base 20 (that is, the left and right ends of the lower flange 21 or the left and right sides at the center of the lower flange 21). The lower surface 22 of the lower flange 21 of the base portion 20 extends from the lower surface 22 of the base 20 in a direction orthogonal to the lower surface 22 and faces the left and right side edges 4a; 4a along the longitudinal direction of the upper surface 4 to be cleaned. Are formed by angle irons connected by fixing means such as welding.
When the base 20 placed on the upper cleaning target surface 4 is moving, the base fall prevention unit 30 is tilted back and forth and left and right away from the upper cleaning target surface 4, or the moving direction F of the base 20 is left and right. When tilted, it collides with the side edge 4a of the upper cleaning target surface 4 to prevent the base 20 from dropping from the upper cleaning target surface 4.

  The prior soil removal means 40 functions as a sediment removal means for pushing away the sediment as sediment accumulated on the upper cleaning target surface 4 and dropping it from the upper cleaning target surface 4. It is connected to the base 20 by the fixing means and the other end side is welded to the other end side (front end side) of the support portion 41 provided so that the other end side extends in front of the base portion 20 (forward in the moving direction of the base portion 20). And a soil discharging portion 42 connected by a fixing means such as the like.

The support part 41 is comprised by the two rebars 43; 44 on either side provided so that it might be located in the right and left with respect to the moving direction F of the base 20, for example.
That is, one end side of the left reinforcing bar 43 is connected by a fixing means such as welding at a position on the left side of the center position between the left and right sides of the upper surface 23 of the lower flange 21 of the base portion 20, and one end side of the right reinforcing bar 44 is connected to the base portion 20 is connected by a fixing means such as welding at a position on the right side of the center position between the left and right of the upper surface 23 of the lower flange 21, and the other end side (front end side) of each reinforcing bar 43; 44 is separated from the base portion 20. Are configured to be close to each other.

In the state in which the base 20 is placed on the upper cleaning target surface 4 (the lower surface 22 of the lower flange 21 is in surface contact with the upper cleaning target surface 4), the earth removal portion 42 is the other end of each reinforcing bar 43; For example, left and right earth excavation plates that extend from the (front end) toward one end and extend upward from the upper cleaning target surface 4 so as to be positioned to the left and right with respect to the moving direction F of the base 20. 45; 46. The left and right earth discharging plates 45; 46 are formed of, for example, steel plates.
The left and right earth discharging plates 45; 46 are provided such that the separation distance between the upper ends is larger than the separation distance between the lower ends. That is, when viewed from the front side in the movement direction F of the base portion 20, the soil removal portion 42 has left and right soil discharge plates 45; 46 formed in a reverse letter C as shown in FIG. When viewed, as shown in FIG. 3, the left and right earth discharging plates 45; 46 form a reverse letter C so that the left and right earth discharging plates 45; The other ends of the reinforcing bars 43; 44 are connected by fixing means such as welding.

The lower ends 48; 48 of the left and right earth removing plates 45; 46 forming the earth removing portion 42 are made of steel plates so as to be positioned closer to the upper cleaning target surface 4 than the lower ends of the left and right reinforcing bars 43; 44. In a state where the reinforcing bars are welded and the base portion 20 is placed on the upper surface to be cleaned 4, as shown in FIG. 4, the lower ends 48; The surface 4 is configured to face the surface with a predetermined interval H. That is, one end side of the left reinforcing bar 43 and one end side of the right reinforcing bar 44 are connected to the upper surface 23 of the lower flange 21 of the base portion 20 via the spacer 47 by fixing means such as welding, so 45; The lower ends 48; 48 of the 46 and the upper surface 4 to be cleaned are opposed to each other with a predetermined distance H therebetween.
Further, the front end side (the other end side) of each reinforcing bar 43; 44 constituting the support portion 41 is bent in a direction away from the upper surface 4 to be cleaned, and the front end lower part 48t of the left and right earth removing plates 45; It is formed in the circular arc shape (R shape) which curves along the bending direction of the front end.

As shown in FIG. 4, when the cutting beam 2 is configured by connecting a plurality of H-shaped steels with a connecting plate 49, bolts 49 a, and nuts 49 b, a connecting plate 49 for connecting the H-shaped steels and Since the head of the bolt 49a protrudes on the upper surface 4 to be cleaned, the interval H is set to a dimension slightly larger than the thickness of the connection plate 49 + the thickness of the head of the bolt 49a = the thickness h. In this case, when the moving body 10 is pulled and moved, it is possible to prevent the left and right earth discharging plates 45; 46 from colliding with the heads of the connection plates 49 and the bolts 49a and hindering the movement.
Further, the front end lower part 48t of each earthing plate 45; 46 is formed in an arc shape that curves along the bending direction of the front end of each reinforcing bar, so that the front end lower part 48t of each earthing plate 45; 46 is temporarily connected. Even if it collides with the head of the plate 49 or the bolt 49a, the arc-shaped front end lower portion 48t can easily get over the head of the connection plate 49 or the bolt 49a.
That is, when towing the moving body 10, since the tow rope 6 is locked to the base portion 20, it is assumed that the distance H is smaller than the thickness h and each of the soil discharge plates 45; When the front end lower part 48t is formed in a square shape, when the front end of each earthing plate 45; 46 and the head of the connection plate 49 or the bolt 49a collide while pulling the moving body 10, Even if the base 20 is floated by pulling up the tow rope 6, it is difficult to float to the front end side of each earthing plate 45; 46, and the front end of each earthing plate 45; 46 and the head of the connection plate 49 or bolt 49 a There is a possibility that the collision state cannot be resolved and the moving body 10 cannot be pulled. For this reason, the distance H is set to be slightly larger than the thickness h, and the lower end 48; 48 of each earth removing plate 45; 46 and the connecting plate 49 or bolt 49a are being pulled while the moving body 10 is being pulled. So that it does not collide with the head.
On the other hand, after the lower ends 48; 48 of the left and right earth removing plates 45; 46 have ridden on the earth and sand accumulated on the heads of the connection plates 49 and the bolts 49a, the front end side of the base 20 floats diagonally. Since it tilts, the base 20 can easily ride on the heads of the connection plate 49 and the bolt 49a. Even if the base 20 collides with the head of the connection plate 49 or the bolt 49a, the front end side of the base 20 is lifted diagonally, so that it is easy to lift the base 20 by pulling up the tow rope 6. The base 20 may be mounted on the connection plate 49 or the head of the bolt 49a by pulling the tow rope 6 while lifting the base 20 so as to lift the tow rope 6.

  As shown in FIG. 1; FIG. 2, the compressed air injection unit 50 includes an upper compressed air injection unit 51 that injects compressed air toward the soil accumulated on the upper cleaning target surface 4, and a lower cleaning target surface 5. And a lower compressed air injection unit 52 that injects compressed air toward the sediment accumulated in the tank.

The upper compressed air injection unit 51 is fixed to the through hole 25 that penetrates the H-shaped steel web 24 that forms the base 20, and the compressed air supplied from the compressed air supply means 60 is the upper cleaning target in front of the base 20. It is constituted by an air guide duct 54 having an injection port 53 to be injected onto the surface 4.
For example, one end opening side of the air guide duct 54 is fixed to a through hole 25 formed at a central position between the left and right sides of the web 24, and the other end side (front end side) extends straight forward in the moving direction F, and the like. The end (front end) opening is formed by a duct configured to function as the injection port 53.

The lower compressed air injection section 52 is fixed to a through hole 26 that penetrates the H-shaped steel web 24 that forms the base 20, and allows compressed air supplied from the compressed air supply means 60 to flow to the left and right in front of the base 20. It is comprised by the wind guide duct 57 provided with the right-and-left injection ports 55; 56 injected on the lower surface 5 to be cleaned.
For example, the air guide duct 57 is fixed to a through-hole 26 formed at one end opening side on the left side between the left and right sides of the web 24, and the other end side (front end side) protrudes forward and branches left and right. After extending downward, which is in the same direction as the extension direction of the fall prevention part 30; 30, the left and right other end (front end) opening side is extended obliquely forward downward, and the left and right other end (front end) opening is jetted. Formed by a duct configured to function as a mouth 55; 56.

  The compressed air supply means 60 includes a first compressed air supply means 61 that supplies compressed air to the upper compressed air injection section 51 and a second compressed air supply means 62 that supplies compressed air to the lower compressed air injection section 52. And comprising.

As shown in FIG. 1, the first compressed air supply means 61 includes a first compressed air supply source 63, a first compressed air supply source 63, and an upper compressed air injection unit 51 fixed to the base 20. It is the structure provided with the wind guide pipe 64 which makes the one end opening of the wind duct 54 communicate.
Therefore, the compressed air supplied to the upper compressed air injection unit 51 by the first compressed air supply means 61 is on the upper cleaning target surface 4 in the moving direction F of the base 20 from the injection port 53 of the upper compressed air injection unit 51. It is configured to be able to blow away the earth and sand on the upper surface 4 to be cleaned by being sprayed toward the earth and sand accumulated in the upper surface.

The second compressed air supply means 62 includes a second compressed air supply source 65, and one end opening of the air guide duct 57 of the lower compressed air injection unit 52 fixed to the second compressed air supply source 65 and the base 20. And a wind guide tube 66 that communicates with each other.
Therefore, the compressed air supplied to the lower compressed air injection section 52 by the second compressed air supply means 62 is moved downward from the respective injection ports 55; 56 of the lower compressed air injection section 52 in the moving direction F of the base 20. By being sprayed toward the earth and sand collected on the side cleaning target surface 5, the earth and sand on the lower side cleaning target surface 5 can be blown off.

A cleaning method using the cleaning device 1 according to the first embodiment will be described.
6; As shown in FIG. 7, two or more persons outside the figure from the front and rear sides of the moving direction F on the ground are connected to the compressed air supply means 60 via the air guide pipe 64 and the air guide pipe 66. The operator 20 places the base portion 20 of the moving body 10 on the upper surface 4 to be cleaned of the beam 2 or the lining girder 3 while being suspended by the tow rope 6. Then, the compressed air supply source 63; 65 of the compressed air supply unit 60 is driven to supply compressed air from the compressed air supply unit 60 to the upper compressed air injection unit 51 and the lower compressed air injection unit 52 while FIG. As shown in FIG. 7, the worker 8 pulls the tow rope 6 from the ground on the front side in the moving direction F to move the moving body 10 in the moving direction F. When the movable body 10 is moved in the movement direction F while sliding the base 20 and the upper cleaning target surface 4, the earth and sand on the upper cleaning target surface 4 are pushed right and left by the left and right earth discharging plates 45; The upper cleaning target surface 4 falls from above the cleaning target surface 4 and is sprayed from the injection port 53 of the upper compressed air injection unit 51 toward the front upper cleaning target surface 4 in the movement direction F of the base 20. The fine earth and sand dust remaining on it is blown away. Further, the front end surface in the movement direction of the base 20 sliding on the upper cleaning target surface 4 collides with the earth and sand remaining on the upper cleaning target surface 4 in front of the base 20 in the movement direction and remains on the upper cleaning target surface 4. The earth and sand that has fallen from the upper surface 4 to be cleaned or transported in the moving direction F of the moving body 10 is removed from the upper surface 4 to be cleaned, so that the upper surface 4 to be cleaned is removed. It is cleaned neatly. Moreover, it is injected toward the earth and sand collected on the lower side cleaning object surface 5 in front of the moving direction F of the base 20 from each of the injection ports 55; Since the earth and sand on the surface 5 are blown away, the lower surface to be cleaned 5 is cleaned cleanly by removing the earth and sand from the upper surface 5 to be cleaned.

Thus, by using the cleaning device 1 of the first embodiment, it is possible to safely and easily remove sediment as sediment accumulated on the long upper cleaning target surface 4 and the lower cleaning target surface 5 extending along the horizontal plane. By removing the soil from the surfaces to be cleaned 4 and 5 by dropping from above the surfaces to be cleaned 4 and 5, these surfaces to be cleaned 4 and 5 can be cleaned at the same time.
In addition, since the prior soil removal means 40 as the sediment removal means is provided, when the amount of sediment deposited on the upper cleaning target surface 4 is large, the sediment can be dropped from the upper cleaning target surface 4 in advance. Therefore, the amount of earth and sand dropped from the upper surface to be cleaned 4 by compressed air injection and the amount of earth and sand removed from the upper surface to be cleaned 4 by sliding of the base 20 of the moving body 10 can be reduced. The earth and sand can be removed from the surface 4, and the upper surface 4 to be cleaned can be cleaned cleanly.
Further, since the moving body 10 includes the left and right base part fall prevention parts 30; 30, when the base part 20 is inclined away from the upper cleaning target face 4 or the moving direction of the base part 20 is inclined, the upper cleaning target face 4 side is provided. It is possible to prevent the base 20 (the moving body 10) from falling on the upper cleaning target surface 4 by colliding with the edge 4a; 4a.
Further, according to the cleaning method using the cleaning device 1 of the first embodiment, the moving body 10 is merely pulled and moved from the front side in the moving direction of the moving body 10, and therefore the surface 4 to be cleaned; 5 can be performed easily and easily.
Moreover, according to the cleaning method using the cleaning apparatus 1 of Embodiment 1, since it can clean without a person getting on the cleaning object surface 4; 5 of the cross beam 2 or the lining girder 3, it is safe.
Furthermore, according to the cleaning method using the cleaning device 1 according to the first embodiment, even if the length of the longitudinal direction of the surface to be cleaned 4; 5 of the cut beam 2 or the lining girder 3 is long, the tow rope Since it becomes possible to cope by changing the length of 6, it is possible to safely clean the cleaning target surface 4; 5 of any length.
The cleaning method using the cleaning device 1 according to the first embodiment is, for example, an upper cleaning target in a cutting site where a place where a pier is installed and where excavated soil is loaded is limited, or in a large depth cutting site where the number of steps of the beam is large The sediment accumulated on the surface 4 and the lower surface to be cleaned 5 can be removed safely and easily, and the effect is great.

In the first embodiment, the cleaning device 1 including the preceding soil removal means 40 is illustrated, but a cleaning measure having a configuration not including the preceding soil removal means 40 may be used.
Moreover, the cleaning measure of the structure which is not provided with the base part fall prevention part 30; 30 may be sufficient.
Moreover, although the example which used the 1st compressed air supply source 63 and the 2nd compressed air supply source 65 separately as a compressed air supply source of the compressed air supply means 60 was shown, one compressed air is used as the compressed air supply source. An air supply source may be used, and the compressed air from the one compressed air supply source may be branched and supplied to the upper compressed air injection unit 51 and the lower compressed air injection unit 52.

Embodiment 2
It is good also as a cleaning device of the composition cleaned by blowing off the earth and sand accumulated on the surface to be cleaned only with compressed air.
