Description

  [Technical Field] The present invention relates to a track-laying greening device for installation on a track lay and a plant growing block used in the device for greening a space between rails.

In recent years, as one of the solutions for urban landscape maintenance, traffic accident countermeasures, CO ₂ reduction, etc., greening of tramways for trams has been planned and has been actually implemented. However, the difficulty of maintaining the planted greenery has also become clear. This is because the purpose of urban landscape improvement and the like is not fulfilled depending on the maintenance management of the greening, and CO ₂ reduction is achieved only insufficiently after all.

  In order to examine this problem, a conventionally proposed greening technique for track laying is investigated. For example, in the invention disclosed in Japanese Patent Application Laid-Open No. 2004-137683, a water passage is provided on the bottom surface along the rail. A greening structure is configured by a dish-type container that is placed side by side and has a pressure resistance, a plant cultivation floor disposed inside the dish-type container, and a greening plant grown on the plant cultivation floor. The plant cultivation floor of this invention is composed of a degree of culture, water retention material, fertilizer, etc., and is formed in a net shape by knitting synthetic resin thread material vertically and horizontally, and the dish-shaped container is left and right by removing its central part. After the plant has taken root to some extent, a good state can be maintained without frequent care. However, in an apparatus that relies on a special plant cultivation floor as in the present invention, the performance of the plant cultivation floor itself is questioned, and the cultivation situation of the plant is influenced thereby, so that the cultivation of plants on orbital laying is performed. We have to wait for future evaluations regarding the maintenance of the state and the time and effort for that.

Japanese Patent Application Laid-Open No. 2005-41 is an invention relating to a greening structure of a tramway that uses a greening container formed entirely of a flexible cloth material. This greening container is deformed according to the shape change of the rail inner surface, so it is easy to obtain a stable state, and it has the advantage that it can be installed stably without being fixed to sleepers, etc. The proposal has not been made and the problem remains. Japanese Patent Application Laid-Open No. 2007-1111030 collects stable (amount of) water throughout the year by installing a plant cultivation room having a tire slip-preventing part on the tramway of a tram and providing a water storage part below the plant cultivation room. It is possible to secure a uniform amount of water by the water channel portion protruding from the bottom surface of the water storage portion. However, although it describes that water is stored using a cast iron greening container, there is no description about drainage, and there is a doubt about understanding about maintenance of greening.

  The present invention has been made paying attention to the above points, and its problem is to provide an orbital greening device that has a watering function and a draining function suitable for the growth of greening plants and is easy to maintain and manage greening. It is to be. Another object of the present invention is to provide a track-laying greening device that can eliminate the need for large-scale work involving traffic regulation such as replacement of greening plants or watering work. . Another object of the present invention is to provide a plant growing block that can be used directly in the above-mentioned orbital greening device and obtain the best results.

In order to solve the above problems, the present invention is to greening the space between the rails, the greening device installed in the track bedding, and disposed between the Relais Lumpur fixing portion are fixed the rails Te, a concrete plant growing blocks for growing a plant and greening space between the rail fixing portion, to form a floor for holding the plant, the upper Kiko Nkurito made for placement on plant growing blocks It has a water supply control unit arranged between the plant holding mat and the plant growing block made of concrete and the plant holding mat, and as a water supply control unit, a plurality of concave portions are formed on the upper surface of the block main body between the engaging structures. And having a water drainage hole in the bottom of the recess for adjusting the amount of water supplied to the plant holding mat. not when configured to have In which it took measures.

  The track floor greening apparatus of the present invention is basically installed on a track floor having sleepers or other rail fixing portions as means for fixing the two rails. In addition to the conventionally known ballast track, the track includes a concrete roadbed with sleepers embedded in roadbed concrete, a ladder sleeper used as a sleeper such as a ballast track, or a slab track using a concrete flat plate for the roadbed, etc. There are various types, and the present invention can be installed in many of these tracks. In addition, the present invention is mainly intended for LRT (Light Rail Transit) systems and tramways for trams, and has the aspect of being part of urban greening.

  The present invention has been improved mainly for the purpose of facilitating the maintenance and management of the greening applied to the track laying, and for plant growth, a concrete plant growth block, a plant holding mat, and a water supply It is necessary to have a control unit as a main component. The plant growing block made of concrete constitutes a main part of the apparatus of the present invention, and is arranged between the rail fixing parts fixing the rails as described later, and the green space between the rail fixing parts is arranged. In order to do so, it provides a place for growing plants, which is the basis for plant growth.

  The plant holding mat is a means for arranging the growing plant on the concrete plant growing block, and forms a floor for holding the plant body and serves as a cultivation soil for the rooted plant. Therefore, it is called a mat because it becomes a floor for growing plants as soil, for example, a material formed by pressing a fibrous material to maintain a certain shape, or a soil component in a bag made of fibrous material The one filled with can be used. In addition, since the soil also forms a single lump, what is composed of only the soil itself corresponds to the plant holding mat.

  Further, a water supply control unit is disposed between the concrete plant growing block and the plant holding mat. It is desirable to keep the water supply to a certain extent, and to supply water by artificial watering when it is judged that the water supply exceeds the limit. However, the upper limit of the amount of water to be stored is determined by the volume of the recess formed in the plant growth block or the amount of water retained by the water retaining material filled therein, and the amount of water exceeding that is drained as needed. Management of water supply is easy because there is no risk of excess. Thus, the water supply control unit in the present invention is intended to manage the water to be supplied to the plants held on the plant holding mat, and the balance between the water retention function and the drainage function is maintained by a specific configuration for the purpose described later. Get drunk.

  The plant growing block used in the track-laying tree planting apparatus according to the present invention is a concrete block main body having a certain size and shape and disposed between sleepers or other rail fixing parts, and the sleepers or other rail fixing parts. In order to fix the block main body by engaging with the inner engaging portion therebetween, it is provided with an engaging structure formed at both ends of the block main body. This block body shall have a standard of a certain size and shape according to the track laying, and a non-standard block body which is not of a certain size and shape may be used together as necessary to lay on the target track laying. To do.

  The plant growing block is disposed as a main body of the plant growing block used in the track-laying planting apparatus according to the present invention, between sleepers or other rail fixing portions that are means for fixing the two rails. Therefore, the block main body is fixed by engaging with the engaging portion inside the sleeper or other rail fixing portion. For this purpose, the block body has an engagement structure at both ends, and based on this engagement structure, the track body is fixed in the lateral direction between two rail fixing parts. Is made. That is, the block body is fixed between the left and right rail fixing portions.

  The block main body has a positioning portion that engages with a fastener such as a dog nail for fixing the rail to a sleeper or other rail fixing portion that supports the rail, and determines its position. As a result, the block body is fixed not only in the lateral direction of the track laying but also in the laying direction, and positioning the block body without providing any special fixing means by using a dog nail or the like as a fixture. You will be able to Therefore, when this configuration is applied, it is assumed that fixtures such as dog nails are installed at regular intervals along the rail.

In order to give the function of the water supply control unit described above to the block main body, the water retaining material constituting the water supply means to the plant holding mat is filled, and a plurality of concave portions are formed on the upper surface of the block main body between the engaging structures. In addition, in order to adjust the amount of water supplied to the plant holding mat, a drain hole is provided in the recess. The recess is a means for accumulating water. Therefore, the planar shape can be selected from any shape such as a square, a rectangle, other polygons, a circle, and an indefinite shape. The water retention material is prepared to obtain a water retention function necessary for water supply control, and the water drain hole is provided to ensure a drainage function necessary for water supply control. As a result, an appropriate amount of water supply management that cannot be obtained simply by accumulating water can be obtained over a long period of time.

  Any water-retaining material can be used as long as it can retain water for a period necessary for the cultivated plant. For example, horticultural foamed soil known by the name of perlite (a foam made by heat-treating oblite and volcanic rock-containing perlite) is suitable for plants such as turf. . Alternatively, other porous particles can be used. For example, these components are generally adjusted to pH 6.5, or are used alone or mixed with other materials without being adjusted when the water retention material is suitable for a specific plant. In addition, there exists what consists of a granular material of the shirasu soil which has a water retention of 30 to 40% in one of the things suitable as a water retention material of plants, such as various kinds of turf, janoge, and sedum.

  Since the present invention is configured and operates as described above, it has a water supply control unit that exhibits a watering function and a drainage function suitable for the growth of greening plants, and is an easy trajectory for maintaining and managing greening. A greening device can be provided. Further, according to the present invention, it is possible to eliminate, as much as possible, large-scale work involving traffic regulation such as replacement of a greening plant or watering work by growing a plant with a plant holding mat. An orbital greening device can be provided. In addition, according to the present invention, it is possible to provide a plant growing block that can be installed on the above-mentioned orbital lay to obtain the best result, thereby implementing the orbital laying greening device in the best mode. There is an effect of being able to do it.

  Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments. FIG. 1 relates to a first example in which a track type greening device 10 according to the present invention and a plant growing block used in the same device are applied to a ladder type track track (a ladder sleeper is used as a ballast track sleeper, see FIG. 13). Is. In order to fix the two rails 11 and 12, the ladder type track laying has sleepers 13 and 14 which are rail fixing portions extending in the rail direction. It has a ladder sleeper structure that is joined at regular intervals using crossbars 15. It is assumed that the sleepers of the ladder sleepers are made of concrete and the ladders are made of metal pipes. Further, the left and right rails 11 and 12 are respectively arranged on the left and right sleepers 13 and 14, and the dog nail is fixed to the fixing tool 16.

  The crossbar 15 is in a lower position than the plant growth block 17 described later and does not conflict. If a certain module is set as the interval of the crosspieces 15 and the installation interval of the crosspieces 15 and the length of the plant growing block 17 are made to coincide with the integral multiple of the module, the construction is further facilitated. Note that, as the fixture 16, fixtures such as dog nails are provided along the rails 11 and 12 at regular intervals. The plant growing block 17 described above is a substantially plate-like block having a structure for providing a plant growing place as a base having a green space between the rail fixing portions (see FIGS. 5 to 9).

The plant growing block 17 is a space between the left and right sleepers 13 and 14 that are rail fixing parts, and a concrete block main body 17a formed with a standard of a certain size and shape, and the left and right sleepers 13 and 14. In order to fix the block main body 17a arranged on the left and right sides, engagement structure portions 18 and 19 formed on the left and right ends of the block main body 17a are provided (see FIGS. 2 to 4). The left and right engaging structure portions 18 and 19 are bent stepwise up and down with respect to the block main body 17a, and engaging mating portions 18a and 19a are provided on the bent lower surface. The engaging portions 13a and 14a in Example 1 are convex corner portions inside the left and right sleepers 13 and 14, and the engaging mating portions 18a and 19a are concave corner portions formed at the lower portions of both end portions of the block body 17a. It is.

  The plant-growing block 17 has positioning portions 18b and 19b for engaging with the dog nails of the fixture 16 and determining the position in the laying direction (rail direction), and the engaging structure portions 18 and 19 on the left and right ends of the block body 17a. Is formed. The illustrated positioning portions 18b and 19b are provided in a shape in which a part of the left and right engaging structure portions 18 and 19 are cut out on the outer sides, and in the illustrated example, a raised portion into which the fixing tool 16 is driven. It has a similar quadrilateral planar shape. By arranging the positioning portions 18b and 19b using the fixing tool 16 as a guide, the plant growing block 17 can be laid on the track lay without any gap. This does not mean that there should be no gap between the plant growing blocks 17, but only the explanation that the illustrated example is so, so that the plant growing block 17 is arranged with a gap or space, Alternatively, whether or not to use the plant growth block 17 having a gap or space is a matter to be determined in actual construction.

  Further, the block body 17a has a plurality of recesses 20 on the upper surface of the block body 17a between the engaging structures so as to fill the water retention material 23 as a means for supplying water to the plants held on the plant holding mat 25. (See FIGS. 5 to 8). As is apparent from FIGS. 7 and 8, the recesses 20 have a square planar shape, are regularly arranged in the front, rear, left, and right directions, and each one is independent, and vertical and horizontal grooves are provided between adjacent recesses. 21a and 21b are provided. Further, a drain hole 22 is formed at the intersection of the vertical and horizontal grooves 21a and 21b. The illustrated recess 20 has a square planar shape, and four of the recesses 20 have a shape that matches the size of one plant holding mat 25 (see FIG. 10).

The water retaining material 23 is filled in the recess 20 of the block body 17a. In the case of Example 1, as the water retention material 23, what consists of a granular material of the shirasu soil which has a water retention rate of 30 to 40% is used. The illustrated water-retaining material 23 is an example using shirasu soil adjusted to a pH of about 6.5. The water-retaining material 23 is filled so as to substantially fill the concave portion 20, and the water in the concave portion is generally supplied to the plant holding mat 25 via the water-retaining material 23. It is configured to be absorbed and supplied to plants. A pipe of the irrigation means 21c is arranged in the vertical groove 21a in which the drain hole 22 is not formed, and is provided so that water can be supplied from a water supply opening opened in the pipe at an appropriate interval. The above-described recess 20, vertical and horizontal grooves 21a and 21b, irrigation means 21c, drainage hole 22 and water retention material 23 constitute a water supply control unit 24 for adjusting the amount of water supplied to the plant holding mat 25 (FIG. 14). reference).

  In the illustrated example 1, the plant holding mat 25 is disposed on the water supply control unit 24 via a water-permeable sheet 26. The water-permeable sheet 26 is made of a nonwoven fabric, and is laid so as to cover the water supply control unit 24 in order to prevent fine sand and the like from accumulating in the recess 20. A plant holding mat 25 in which plants 27 are planted is disposed on a water-permeable sheet 26. The plant holding mat 25 in the illustrated example is formed by, for example, compressing a fibrous material into a square shape. (See FIG. 10). In the figure, reference numeral 28 denotes a ballast.

  In Example 1 of the present invention configured as described above, the plant growing block 17 is arranged on a ladder-type track laying as shown in FIG. 1, and the engaging portions 13a and 14a of the left and right sleepers 13 and 14 are arranged. The plant-growing block 17 is laid on the track lay so that the mating engagement portions 18a and 19a are engaged with each other, and the positioning portions 18b and 19b are disposed therewith the fixing tool 16 as a guide. The load of the plant growing block 17 is supported by the sleepers 13 and 14 at both left and right ends, and is directly supported by the ballast 28 at the intermediate portion (FIG. 13A).

  In this way, the plant growing block 17 is arranged and laid in the space S between the rails that need to be greened, and the recess 20 of each plant growing block 17 is filled with a water retention material, and the vertical groove 21a is filled. Installs the pipe of the irrigation means 21c, covers the upper surface of the recess 20 with the sheet 26, and arranges the plant holding mat 25 (FIG. 10). After construction, by passing water through the pipe of the irrigation means 21c, the water flows along the vertical and horizontal grooves 21a and 21b (FIG. 14), fills the concave portion 20, and is absorbed by the water retaining material 23. The symbol W indicates the water surface. When water reaches the plant holding mat 25, the plant 27 absorbs moisture inside the floor tissue, and eventually grows down the roots. As a result, the space S between the rails is greened. .

  Since the cultivated plant 27 has water supply due to precipitation, irrigation is unnecessary while sufficient precipitation is obtained, and excessively supplied water is discharged from the drain hole 22 as needed. In particular, in a situation where the lower part of the apparatus is a ballast 28 with good drainage, it is difficult for the roots to be constantly immersed in water. On the contrary, even if the sunshine continues, until the water disappears, the first is the evaporation of the brine in the recess 20, the second is the water stored in the water retaining material 23, and the third is the water stored in the plant holding mat 25. It has the ability to hold water and multi-stage water retention, so frequent watering is unnecessary unless it occurs even in extreme weather.

  Although it has already been described that there are various types of track laying in addition to the ladder system described above, an example 2 in which the apparatus 30 of the present invention is applied to a ballast track, which is one well-known type, will be described. . FIG. 15 shows a structure in which sleepers 33 for fixing the rails 31 and 32 are arranged on the ballast at regular intervals, and the apparatus 30 of the present invention is constructed using the cross-shaped sleepers 33. To do. In Example 2, the left and right rails 31, 32 are arranged on the front and rear sleepers 33, 33..., And dog nails are fixed to the fixture 36.

  The sleeper 33 is located at a lower position than the plant growth block 37 described later. In the example 2, the plant growth block 37 in which the interval between the sleepers 33 is configured as a fixed module is arranged in the space between the sleepers. That is, Example 2 has a configuration in which the length of the plant growing block 37 is made to coincide with the above module or an integral multiple or a fraction of an integral number thereof. The plant growing block 37 of Example 2 is a bonnet-like shape with four sides rising, but a mouth portion 37b through which the pipe 41c is passed is formed at the rising portions of the two front and rear sides. In addition, the dog nail which is the fixing tool 36 is provided along the rails 31 and 32 at regular intervals.

  The plant growing block 37 includes a concrete block main body 37a, which is arranged between the front and rear sleepers 33, 33... In order to fix the block main body 37a disposed between them, engaging structure portions 38 and 39 formed at both front and rear ends of the block main body 37a are provided (see FIGS. 19 to 20). The front and rear engaging structures 38 and 39 are bent stepwise up and down with respect to the block main body 37a, and engaging mating portions 38a and 39a are provided on the bent lower surface. The engaging portions 33a, 33b in Example 2 are convex corner-like opposing portions inside the front and rear sleepers 33, 33... And the engaging mating portions 38a, 39a are lower portions of both front and rear end portions of the block body 17a. It is the concave-angle-shaped part formed in.

  Positioning portions 38b and 39b for engaging the plant growing block 37 with dog nails as a fixture 36 and determining the position in the laying direction (rail direction) are the front and rear ends and the left and right ends of the block body 17a, that is, the engaging structure portion 38. , 39 are formed at four corners. The illustrated positioning portions 38b and 39b are provided in a shape in which the corners of the front and rear engaging structure portions 38 and 39 are cut into squares. In the illustrated example, the positioning portions 38b and 39b are similar to the raised portions into which the fixture 36 is driven. It is formed in a quadrilateral planar shape. Thus, the plant growing block 37 is laid on the track floor without any gaps. This is the same as Example 1 in that it does not mean that there should be no gap between the plant growing blocks 37.

  The block main body 37a has a plurality of concave portions 40 on the upper surface of the block main body 37a between the engaging structure portions in order to fill the water retaining material 43 as water supply means to the plants held on the plant holding mat 45. (See FIGS. 18 and 19). As is clear from the figure, the recesses 40 have a square planar shape, are regularly arranged in the front-rear and left-right directions, and each one is independent, and vertical and horizontal grooves 41a and 41b are provided between adjacent recesses. Is provided. Further, a drain hole 42 is formed at the intersection of the vertical and horizontal grooves 41a and 41b. The illustrated recess 40 has a square planar shape, and four of the recesses are formed in a shape that matches the size of one plant holding mat 45 (see FIG. 18).

A water retaining material 43 is filled in the recess 40 of the block body 37a. As the water retention material 43 in Example 2, a sheet-like material having a water retention rate of 70 to 80% and having a porous structure is used. The water retaining material 43 of Example 2 is an example using a greening base soil adjusted to a pH of about 6.5. The water retaining material 43 is filled with the recessed portion 40 substantially filled therein, and the water in the recessed portion is substantially filled with the plant retaining mat 45 through the water retaining material 43. It is configured to absorb and supply to plants. The pipe of the irrigation means 41c is arranged in the vertical groove 41a in which the water drain hole 42 is not formed, and is provided so that water can be supplied from a water supply opening opened in the pipe at an arbitrary interval. The concave portion 40, the vertical and horizontal grooves 41a and 41b, the irrigation means 41c, the drain hole 42, and the water retaining material 43 described above constitute a water supply control unit 44 for adjusting the amount of water supplied to the plant holding mat 45 (FIG. 18).

  Also in Example 2 of the present invention, the plant holding mat 45 is disposed on the water supply control unit 44 via a water-permeable sheet 46. The purpose of use of the water-permeable sheet 46 is the same as in Example 1. And a plant is planted by the plant holding mat 45, and the plant holding mat 25 of Example 2 is formed with the greening base soil. Therefore, it can be understood that Example 2 of the present invention can achieve the same object as Example 1 and obtain the effect.

  The present invention is configured as described above, and a space S of a tramway such as a tram or LRT, in particular, a space S between rails is covered with various plants such as various grasses, janohige, sedum, or lichens, It is useful for greening, and it facilitates the maintenance of cultivated plants by simplifying watering and draining. Therefore, it is possible to realize greening without requiring difficult construction, such as orbital sloped leveling or construction of drainage facilities, which has been an important matter in conventional greening. In addition, facilitating maintenance and management of greening plants makes it easy to maintain the cultivation state of plants for a long period of time, reducing the frequency of traffic regulations such as blocking traffic for management or restricting traffic. This makes it possible to improve the tolerance to adverse conditions that plants suffer from road vehicles other than trams, and to vigorously grow plants.

  Although the purpose is to green the space between the rails, it is clear that the present invention can also be used for the force of the adjacent portion of the rail. In that case, as a part of the rail fixing part for holding the plant growing block, a paving stone, a curbstone, or the like installed on the track laying can be used. Moreover, even if it is not as a rail for running a vehicle, if it is a planar structure formed using a rail-shaped material, this invention can be utilized for the greening.
