Abstract

PURPOSE:To prevent the degradation of a slope by a method in which main frames having a vertical wall are connected in a slant lattice form to the upside of the main part with a rectangular cross section by the first connector and the main frame at the lowermost end is connected with the second connector with an opening for draining to promote the draining work. CONSTITUTION:Main frames 2 are laid between first connectors 6 fixed to a slope by turning its water arresting part upwards. Also, the second-fourth connectors 7-9 are fixed to the lower, left and right, and upper sides of a drain frame 28, the ends of the main frames 2 are penetrated into the ground, and the frame 28 is buried by covering it with soil until the upper end of the vertical wall 4 of the main frames 2 is leveled with the ground surface. Water present in the surface layer of the slope flows down along the upside of the main frame 2, goes into the entrance paths of the first-third connectors 6-8, and further goes down inside the main part 3 of the other main frame 2. The arrested water is collected in the main part 3 and discharged from the opening of the second connector 7 at the lowermost end to the outside of the slope.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frame body that serves to prevent collapse of sloped surfaces and drains, which are often found in cut-outs for railways, roads, etc., and in sub-site development sites.

Sloped surfaces seen in cutouts, etc.! After construction, it is common practice to cover the surface with grass or the like to protect it from collapsing due to rain, etc. At the same time, a framework is installed on the surface of the slope to protect the slope until the grass or the like grows and to function as a reinforcing frame even after the grass grows.

In this way, the framework is made of, for example, synthetic resin or metal.
A member 1.1 with a road-shaped cross section as shown in the figure is made, and a large number of the members 1.1 are connected with bolts and nuts to construct a base mesh-shaped framework on an inclined surface as shown in Fig. 2. This is to suppress the surface of the inclined surface.

However, when preventing the slope from collapsing using such a conventional framework, the following problems occur. In other words, since such a framework is simply fixed to the surface of a slope and presses down on the surface, it is not possible to drain away the moisture that accumulates within the slope after rain, and it is not effective in preventing collapse. Can not do it. In addition, to prevent the framework from floating up from the slope, the intersection part (second
Part a) is fixed to the slope □ using wooden stakes, U-shaped metal rods, etc., but the intersection is where rainwater that falls on the slope is most likely to accumulate as it is guided by the framework. Therefore, the wooden stakes, U-shaped metal rods, etc. mentioned above are susceptible to corrosion, and when they corrode, the framework gradually floats up onto the slope, leaving it in an unstable state where it simply rests on the slope. turn into. Furthermore, since the framework is visible on the ground surface, grass, etc. can be left on the slope.
``Even when the grass grows, it grows avoiding the framework, and the existence of the framework can be seen when viewed from a distance, making the slope look artificial, and under special conditions such as natural parks. The collapse prevention/drainage frame of the slope trap of the present invention solves the above problems of the conventional construction method.
□ Hereinafter, the present invention will be explained with reference to drawings showing examples.

Figures 3 and 4 show the main frame material 2 used in the frame of the present invention to prevent sloped surfaces from collapsing and to drain moisture from the surface layer of the surfaces. The main frame material 2 has a vertical wall 4 formed on the upper surface of a main part 3 having a rectangular cross section, and a partition wall 5 is formed inside the main part 3 to partition the inside of the main part 3 into upper and lower parts for reinforcement. . Both ends of the standing wall 4 formed on the upper surface of the main part 3 are slightly cut off so that both ends of the main part 3 can be inserted into a connector to be described later.

As shown in FIG. 5, the main frame member 2 formed in this way is connected in large numbers in a diagonal lattice shape by the first to sixth connectors 6 to 11, and is connected to the upper surface of the vertical wall 4 on the surface layer of the inclined surface. It will be buried so that it is almost flush with the ground surface. Moisture that has accumulated in the slope behind the gate is drained onto the upper side of the main frame members 2.2 (located above the slope (14 side)) and directed toward the connection part 1 of each main frame member 2.2. The flow 1 flows into the main part 3 from this connection part, flows inside this main part 3, and is discharged outside the slope. In addition to the function (3) of connecting the main parts 3 and 3 of the main frame members 2 and 2, the connectors installed in places where moisture collects have the function of capturing moisture contained in the surrounding soil. It has both.

Next, the structure and function of each connector will be explained.

First, the first connector 6 that connects the main frame members 2.2 disposed diagonally in an X-shape is shown in FIGS. It consists of a lid body 13 like this. A circular tube portion 15 is formed in the center of the substrate 14 constituting the main portion 12, and extends through the substrate 14 in the vertical direction. A plurality of vertical walls 16, 17, and 18 are formed at intervals on the outer peripheral edge of the substrate 14, and the main portion 3 of the main frame member 2 described above can be inserted between each vertical wall. It has become. That is, the lower edge of the substrate 14 (upper and lower are the seventh
According to the diagram. ) is formed with a first chevron-shaped vertical wall 16, and second chevron-shaped vertical walls 17 and 17 are formed on both left and right edges, respectively.
The space between the first and second standing walls 16 and 17 is as above (4). Further, third standing walls 18.18 parallel to the second standing walls 17.17 are formed on both left and right sides of the upper part of the substrate 14,
An insertion portion 19.19 for inserting the main portion 3 is also provided between the second and third compatible walls. Further, between the left and right third standing walls 18, ]8, a plurality of square columns 21.21 are formed symmetrically with respect to the standing wall 20 at the center of the upper edge. A curved flow path is provided.

On the other hand, the lid body 13 attached to such a main part 12 is
As shown in FIGS. 0 to 12, first to third hanging walls 23 and 24 are provided at the upper, lower, left, and right edges of the substrate 22 with spaces between them.
．． 25 is formed. Each hanging wall 23.24.25 is
It fits over the upper end of the vertical wall 16.17.18 of the main part 12, and is formed lower than the vertical wall 16.17.18. Further, an X-shaped vertical wall 26 is formed on the upper surface of the base plate 14 of the lid body 13, and a column 27 is suspended from the lower surface. The support 27 on the lower surface aligns with the vertical wall 4.4 on the upper surface of the upper frame member 2 and serves to connect this vertical wall 4.4, and the upper surface of the support 27 serves as a lower edge trap of the vertical wall 20 on the upper center of the main part 12. This prevents the vertical wall 20 from bending due to earth pressure and blocking the curved flow path provided in the upper part of the main part 12 when the first connector 6 is buried underground. The main frame member 2.2 shown in FIGS. 3 and 4 is connected to an X-shape as shown in part b of FIG. In order to connect the end of this main frame material 2 to the main part 12
Insert it into the four insertion parts 19 and 19 of the lid body 13 from above.
Just cover it.

Next, as shown in FIG. 5, a main frame horizontally arranged to constitute the lower side of the drainage frame 28 is formed by connecting a large number of main frame members 2, 1, 2 in a diagonal grid pattern. The main frame arranged at an angle with the material 2.2: the part that connects the lower end of the base 2.2 (the fifth
The second connector 7 used in section C in the figure will be explained. This second connection and the lid 3 as shown in FIGS.
0 and is configured as shown in FIGS. 17 and 18. The main part 29 is formed symmetrically as shown in FIG. 13, and has a main frame horizontally disposed between vertical walls 32 and 33 formed in parallel with each other at intervals in the horizontal direction on the upper surface of the substrate 31. First insertion part 3 for inserting the end of material 2.2
4.34 is inclined by 45 degrees with respect to the standing walls 32.33, and the main frame member 2 is arranged in an inclined direction between the standing walls 35.36 formed parallel to each other and spaced apart on the upper surface of the substrate 31.
．． A second insertion part 37,37 is provided for inserting the lower end of the second part.

A small amount of carbon is applied to the opposing side surfaces of a horizontal vertical wall 32 and an inclined vertical wall 35 formed adjacent to the upper surface of the substrate 31.
Projections 38 and 39 are formed at different positions to form a curved flow path between the compatible walls 32 and 35. Reference numeral 40 denotes a spacer inserted between the compatible walls 32.35, which prevents the vertical walls 32.35 from moving both sides. Moreover, a plurality of standing pillars 41.42 are formed between the standing walls 36.36 formed near the center of the uppermost part, and protrusions 43. 43 to form a curved flow path. Furthermore, the standing wall closest to the bottom 33.33
A weir plate part 44.44 that does not reach the opposing standing wall 32.32 is formed on the upper side of the end near the center of 1-1.A U-groove part 45 is extended downward from between this art platform plate part 44.44. It is set up as follows. The bottom surface of this U-groove portion 45 is inclined upwardly with respect to the top surface of the substrate 31. At the center of the substrate 31, a circular tube portion 46 is formed which vertically passes through the substrate 31, similar to the main portion 12 of the first connector 6 described above.

On the other hand, the lid body 30 attached to the main portion 29 has the 15th to 1st
As shown in Figure 6, each vertical wall 32, 33, 35 of the main part 29
．． The base flexure having a hanging wall 47, 48, 49 formed on the end edge that fits over the upper edge of 36 is also connected to a second connecting device consisting of (8), thereby blocking the bent flow path. A standing wall 51 is formed that matches the standing wall 4.4 on the upper surface of the main frame member 2.2. Furthermore,
A cover piece 52 having an arc-shaped cross section and covering the upper side of the U-groove portion 45 of the main portion 29 is formed on the lower end edge of the lower hanging wall 47 .

Further, a column 53 is formed at the center of the lower surface of the substrate 50 to abut against the lower surface of the upper end of the column 41 at the center of the upper' side edge of the main portion 29 to prevent the column 41 from being deformed. The second connector 7 consisting of the main body s29 and the lid body 30 formed in this way is assembled as shown in FIGS. 17 and 18, but in order to connect the main frame member 2.2, It is sufficient to simply insert the ends of the frame member 2.2 into the four insertion portions 34, 37 of the main portion 29 and cover the lid 30 from above.

Next, as shown in parts d and e of Fig. 5, a third part is connected to the main frame member 2.2 disposed in the diagonal direction to the main frame member 2.2 disposed in the vertical direction on the inclined surface. The fitting 8.8 is exactly the same as the second fitting 7 described above. If the second connector 7 is rotated 90 degrees clockwise from the orientation shown in FIG.
If used in a state rotated by 0 degrees, it can be used as a connector for the 0 portion in FIG. 5. However, in this case, the end opening 54 (FIG. 18) of the tubular passage formed between the U-groove portion 45 of the main portion 29 and the cover piece 52 of the lid body 30 is closed. In this case, moisture flowing down the main frame member 2 in the vertical direction does not flow into the U-groove portion 45 because of the weir plate portion 44. However, if the third connector 8 is not shared with the second connector 7 but has a separate shape, the 19th to 20th
As shown in the figure,' the main part 55 has a lid body 56□・1' as shown in FIGS. 21 to 20.
□1 can also be attached to form the third connector 8.

Next, as shown in part f in FIG.
As shown in FIGS. 23 to 25, an insertion portion 58, 58 into which the main portion 3 of the main frame member 2 is inserted is formed on the upper surface of the circular tube portion 57 in a substantially perpendicular direction. Since this fourth connector 9 simply locks the upper end of the main frame member 2.2, a lid is not necessary.

Furthermore, the fifth connector 10 used at both upper corners of FIG. The configuration is similar to that of the fourth connector 9. Further, the sixth connector 11 used at both corners of the lower end in FIG. 5 can be configured in substantially the same manner as the second connector 7 by making the insertion portions have different angles.

Next, a large number of main frame members □ configured as described above.

2.2 and the second:~sixth connectors 6 to 11 are joined... In order to construct the drainage frame 28 as shown in Fig. One connector 6.6 is connected to the water catching part of the main part 12 (the part of the curved flow path made up of the prisms 21 and 21).
The main frame member 2. is positioned above the inclined surface and fixed by a stake (11) that penetrates the circular pipe portion 15 of the main portion 12, and the main frame member 2.
Kake hands 2. In addition, a thirteenth
Similarly, the second connector 7 as shown in Fig. 18 is attached to the circular pipe part 4.
6, and the first and second insertion portions 34
．． Insert the end of the main frame material 2 into 37. This second connector 7
As will be described later, when the entire drainage frame 28 is buried on an inclined surface, the opening 54 can be directly brought out of the inclined surface, or the end of another pipe can be connected to this opening 54. The water sent to the second connector 7 through this pipe is discharged to the outside of the slope. Furthermore, the third connector 8 is similarly fixed to the left and right sides of the drainage frame 28 with stakes, and the ends of the main frame member 2 are inserted. Further, a fourth connector 9 is fixed to the upper side of the drainage frame member 28 with a stake to lock the upper end of the main frame member 2. Furthermore, the four corners of the drainage frame material 28 can be connected to the fifth and sixth connectors 10.11 as described above, or the connectors can be connected as shown in (12), and the drainage frame can be attached to the upper surface of the slope. Once the body 28 is fixed, soil is further placed on top of the drainage frame 28 until the upper end surface of the vertical wall 4 of the main frame material 2 is flush with the ground surface, and the entire drainage frame 28 is placed on a sloped surface. Bury it in the surface layer. At this time,
Is it possible to put crushed stone around the water catchment part (a curved channel made of square pillars, etc., or a net) provided in the third connector to prevent the water passageway that makes up this water catchment part from becoming clogged? Make it.

Next, a description will be given of the function of the collapse prevention/drainage frame on an inclined surface according to the present invention, in which the above-mentioned components are joined and buried in the surface layer of the inclined surface.

Among the moisture contained in the ground, the moisture present in the surface layer of the slope flows down along the upper surface of the main frame member 2 and reaches the connecting portion of the main frame member 2.2. As mentioned above, the first to third connectors 6 to 8 that connect this main frame member 2.2 are curved channels (each connector may also be formed into ), the moisture flowing down the upper surface of the main frame material 2 as described above enters into the first to third connectors 6 to 8, and further flows into the main part 3 of another main frame material 2. , and further flows down the inside of this main frame material 2 . The collection of this moisture is achieved by a large number of connectors 6 that make up the drainage frame 28.
．． The collected moisture is collected in the main part 3 of the main frame member 2 and is discharged from the opening 54 of the second connector 7 at the bottom to the outside of the inclined surface.

The anti-collapse/drainage frame for sloped surfaces of the present invention is configured and operates as described above, so that moisture accumulated within the sloped surface due to rainfall can be efficiently drained, and the main frame member 2
．． In addition to partitioning the surface layer into a diagonal lattice pattern by 2, the effect of "collapse market" 1 is large.It also appears on the surface of an inclined surface.4.
Ai□□yo□mu°(yo.,. Since it is only an air surface, after grass grows on the slope, the existence of the drainage frame will not be known,
It has various excellent effects such as not damaging the beauty of natural parks etc.
