Abstract

PURPOSE:To prevent the downward movement of soil on the upper part and to prevent the occurrence of great cleavage by connecting the intermediate parts of the main frames constituting the upper diagonal sides of square parts for the hatched portion of a drain frame by sheathing boards in the horizontal direction. CONSTITUTION:Connectors 60 are provided to the intermediate parts of main frames 2 forming the upper diagonal sides of square parts, which are to be provided on a slope, and sheathing boards 61 of the same shape as the main frame 2 are supported by both connectors 2. The connector 60 has a coupling groove 62 to be coupled with the upper vertical wall 4 of the main frame 2 and also a coupling groove 64 to be coupled with the upper vertical wall 63 of the sheathing board 61 and is fixed to the slope by piles 67 inserted through the round holes 66 of the base plate 65. Since, in the square portion formed by the main frames 2, the upper trianglar portion is partitioned by the sheathing board 61, downward movement of soil above the sheathing board 61 can be avoided, and therefore, the occurrence of a great cleavage between the frame and soil can be prevented.

Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to an improvement in a drainage frame for preventing collapse of slopes, which are often found in cut-outs for railways, roads, etc., and in residential development sites.

(Background technology) In order to prevent sloped surfaces found in cut-outs and the like from collapsing due to rain, etc. after construction, the surface is often covered with grass or the like to protect the surface. At the same time, a framework is installed on the surface of the slope to protect the slope until grass or the like grows and to function as a reinforcing frame even after the grass grows.

Such a framework is made of synthetic resin or metal, for example, with a first
A member 1.1 having an abbreviated 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 diagonal lattice-like 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 disadvantages occur. In other words, since such a framework is simply fixed to the surface of the tilting surface and suppressing the linear surface, it is not possible to drain the moisture that accumulates within the tilted surface after rain, making it impossible to fully prevent collapse. unable to perform. In addition, the framework is lifted from the slope 1. The intersection of the framework (Fig. 2a)
(1) are fixed to the slope using wooden stakes, U-shaped metal rods, etc., but since the intersection is the part where rainwater that falls on the slope is most likely to accumulate as it is guided by the framework, The wooden stakes and U-shaped metal rods mentioned above are prone to corrosion, and if they corrode, the framework will gradually float up to the slope, leaving it in an unstable state where it simply rests on the slope. Put it away. Furthermore, since the framework is visible on the ground surface, even if grass, etc. grows on a slope, the grass will grow avoiding the framework, and the presence of the framework can be known when viewed from a distance. This gives the slope an artificial feel, which is undesirable under special conditions such as natural parks, as it spoils the aesthetics.

In order to eliminate such inconveniences, in the present invention, first, a large number of main frame members each having a fixed length and having a vertical wall on the upper surface of the main part having a rectangular cross section are connected in a diagonal lattice shape using first connectors. One connector has a flow path that introduces the moisture that has flowed down the side surface of the main frame material into the inside, and the second connector that is connected to the lower end of the main frame material at the lowest end has a flow path that introduces moisture that has flowed down inside this main frame material. He invented a collapse prevention/drainage frame on a sloped surface having an opening 1 for discharging water out of the sloped surface (Japanese Patent Application No. 77505/1982).

First, to explain in detail the collapse prevention/drainage frame of the earlier invention, Figures 3 and 4 show that it is used in the frame of the earlier invention to prevent collapse of sloped surfaces and drain moisture from the wrinkled surface layer.

In the collapse prevention/drainage frame body according to the previous invention, the main frame member 2 formed in this manner is connected in a plurality in a diagonal lattice shape by first to sixth connectors 6 to 11, as shown in FIG. They are combined and buried in the surface layer of the slope so that the upper surface of the standing wall 4 is approximately flush with the ground surface. After rain, the moisture accumulated in the sloped surface is guided by the upper side surface of the main frame member 2.2 (the side surface located above the sloped surface) and flows toward the connection part of each main frame member 2.2. , flows into the main part 3 from this connecting part, flows inside this main part 3, and is discharged to the outside of the inclined surface. For this reason, the connection tool installed in the place where the moisture guided on the upper side of the main frame material 2.2 collects has the function of connecting the main parts 3, 3 of the main frame materials 2, 2, and also the function of connecting the main parts 3, 3 of the main frame materials 2, 2. It also has a water-capturing function that draws the moisture contained in the water inside.

Next, as shown in the WSS diagram, the main frame members 2.2 are arranged horizontally to form the lower side of the drainage frame 28, which is formed by connecting a large number of main frame members 2.2 in a diagonal grid pattern. The second connector 7 used for the part connecting the lower end of the main frame member 2.2 arranged at an angle (portion C in Fig. 5) has a main part 29 as shown in Figs. , a lid body 30 as shown in FIGS.
It is constructed as shown in FIGS. 17 and 18 in combination. The main portion 29 is formed symmetrically as shown in FIG. 13, and is horizontally disposed between vertical walls 32 and 33 formed parallel to each other at intervals in the horizontal direction of the drawing on the − side of the substrate 31. The first insertion part 34.34 for inserting the end of the installed main frame material 2.2 is placed on the upper surface of the substrate 31 at an angle of 45 degrees with respect to the vertical wall 32.33, in a state parallel to each other. Second insertion portions 37.37 are provided for inserting the lower ends of the main frame members 2.2 arranged in the inclined direction between the vertical walls 35.36 formed at intervals. Protrusions 38 and 39 are formed at slightly different positions on the opposite sides of the horizontal standing wall 32 and the inclined standing wall 35 formed adjacent to the upper surface of the substrate 31, and between the compatible walls 32 and 35. It forms a flow path that curves inward. 40 is a spacer inserted between the compatible walls 32.35, which prevents the curved flow path 1 from being blocked by bending of the vertical walls 32.35. Also, the standing wall 36.36 formed near the top center
A plurality of standing pillars 41.42 are formed between them, and a curved flow path is formed between these standing pillars 41.42 and a protrusion 43.43 formed on the side surface of the standing wall 36.36. ing. Further, a weir plate portion 44.44 that does not reach the opposing vertical wall 32.32 is formed on the upper side of the center-side end of the standing walls 33, 33 closest to the bottom, and from between the two tower plate portions 44.44 A U groove portion 45 is provided toward the lower side. The bottom surface of this U-groove portion 45 is inclined vertically 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 penetrates the substrate 31 in a 2F direction, similar to the main portion 12 of the first connector 6 described above. On the other hand, this main part 2
As shown in FIGS. The upper surface of the substrate 50 formed on the edge portion is aligned with the vertical wall 4.4 of the -1; A standing wall 51 is formed. Furthermore,
A cover piece 52 is formed at the lower end edge of the hanging wall 47 on the side of the dome, and has an arc-shaped cross section and covers the upper side of the U-groove portion 45 of the main portion 29 marked with "." Also.

A column 53 is formed at the center of the lower surface of the substrate 50 to abut against the lower side surface of the upper end of the column 41 at the center of the upper edge of the main portion 29 to prevent the column 41 from being deformed.

The second connector 7 consisting of the main portion 29 and the lid 3o formed in this way is assembled as shown in FIGS. 17 and 18, but in order to connect the main frame member 2.2, this Main frame material 2, 2
All you have to do is insert the ends of the main part 29 into the four insertion parts 34 and 37, and then cover them with the lid 3o.

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 connector 8.8 can be exactly the same as the second connector 7 described above, just by changing the orientation. In other words, if the second connector 7 is rotated 90 degrees clockwise from the orientation shown in Figure 13, it can be used as the connector d in Figure 5 when also rotated 90 degrees counterclockwise. If used, they can each be used as a connector for the part e in FIG. 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 3o 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 main part 55 as shown in FIGS. The third connector 8 can also be formed by attaching a lid 56.

Next, as shown in part f in FIG. 5, the fourth connector 9 that connects the upper ends of the main frame members 2 and 2 at the upper end of the drain frame 28 is connected 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 substantially perpendicularly to the two side surfaces of the circular tube portion 57. This fourth connector 9 is
Since it simply locks the upper end of the main frame member 2.2,
A lid is not required.

Furthermore, a fifth connector 10 used at both corners of the first end in FIG.
This is constructed in the same manner as the fourth connector 9 described above, except that the angle formed by the two insertion portions into which the main portion 3 of the main frame member 2 is inserted is 45 degrees. 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, to construct a drainage frame 28 as shown in FIG. 5 by joining a large number of main frame members 2.2 constructed as described above and the first to sixth connectors 6 to 11, , a large number of first connectors 6.6 are placed on the 4 inclined planes, and the water extraction part of the main part 12 (the part of the curved flow path made up of the square columns 21.21) is located above the inclined plane, Fixed by a stake passing through the circular tube part 15 of the main part 12.1. The main frame members 2, 2 are passed between these connectors 6.6. In addition, the lower side of the drainage frame 28 is provided with 13th to
Similarly, the second connector 7 as shown in FIG.
The first and second insertion portions 34.
Insert the end of the main frame material 2 into 37. When the entire drainage frame 28 is buried on an inclined surface, the opening 54 of the second connector 7 can be directly brought out of the inclined surface, or the end of another pipe can be connected to this opening 54, and this pipe can be connected to the opening 54. The water sent to the second connector 7 through the drain is discharged to the outside of the inclined surface. 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. In addition, the fourth connector 9 is fixed to the upper side of the drainage frame 28 with a stake, and the main frame member 2
Lock the upper end of the Furthermore, the four corners of the drain frame 28 are also connected to the fifth and sixth connectors 10.11 as described above, or the end openings of the main frame member 2 are closed without providing any connectors. .

Once the drainage frame 28 has been fixed to the upper surface of the slope in this way, the drain frame 2B is further fixed until the upper end surface of the vertical wall 4 of the main frame material 2 matches the ground surface. Then, the entire drainage frame 28 is buried in the surface layer of the slope.

When the drainage frame is buried in the surface layer of the slope surface due to the collapse of the slope surface of the previous invention in which each component is joined in this way, the moisture contained in the ground will be absorbed by the surface layer of the slope surface. flows along the upper side of the main frame member 2 and reaches the connection part of this main frame member 2.2. As described above, the first to third connectors 6 to 8 that connect the upper frame material 2.2 have curved wave paths that take moisture flowing from above into the main frame. The moisture flowing down the upper surface of the material 2 enters into the first to third connectors 6 to 8, and further flows into the inside of the main part 3 of another main frame material 2, and the moisture flows down the upper surface of the main frame material 2. It flows further down the inside. This moisture collection is performed for each of the many connectors 6°7.8 that make up the drainage frame 28, and the collected moisture is collected in the main part 3 of the main frame member 2 and sent to the bottom It is discharged from the opening 54 of the second connector 7 to the outside of the inclined surface.

The anti-collapse/drainage frame for sloped surfaces according to the previous invention is configured and operates as described in section 2 below, so that moisture accumulated within the sloped surface due to rainfall can be efficiently drained, and the main frame material 2. 2 partitions the surface surface into a diagonal lattice pattern, which has a great effect in preventing collapse, and what is visible on the surface of the RTR411 surface is only the top end of the vertical wall between the narrow main frame material and each connector. Therefore, after grass grows on the slope, the existence of the drainage frame becomes invisible, and it has various excellent effects such as not spoiling the beauty of natural parks etc. However, as described below, causing inconvenience.

That is, when burying the collapse-proof non-drainage frame according to the previous invention on a slope, the drainage frame 28 is placed on the slope that is lower than the slope after completion by the height of the main frame material 2. (assemble on the surface), then cover the main frame material 2 and each connector until they are covered. Therefore, the soil that is added later and is equal to the height of the main frame material 2 is divided by each main frame material 2.2. In this way, the soil in the parts divided by the main frame material 2.2 will be added later, so even if it is compacted after being put in, the comparative terms and conditions will not apply. A gap will be created between the frame material and the side surface. That is, as shown by the chain line in Fig. 26, when the soil in the square area surrounded by the main frame material 2.2 is compacted, a relatively large gap 59 is created at the top of this square area, and the grass in this area is interrupted. This is not desirable because the sloped surface looks unnatural.

(Purpose of the Wooden Invention) In order to solve the above-mentioned problems, the present invention provides a method for preventing collapse and draining on sloped surfaces so that there is no large gap between the main frame material and the soil even after the soil is compacted. The purpose is to provide a framework.

(Structure of the present invention) The collapse-preventing non-drainage frame on an inclined surface of the present invention is the same as that of the drainage frame of the previous invention which is configured and operated as described above. Among the frame materials, a horizontal weir plate is provided that connects the middle parts of the main frame materials that constitute the upper oblique side of each square portion, and each square portion surrounded on four sides by the main frame materials This prevents the soil inside from moving significantly downward.

That is, as shown in FIG. 27, a connecting tool 60.
are provided, and both ends of a weir plate 61 having the same shape as the main frame member 2 are supported by both connectors 60 and 60. Therefore, the above-mentioned square part is partitioned off from the upper triangular part by this weir plate 61.

The connector 60 is connected to the main frame member 2 as shown in FIGS.
The locking IF groove 62 that fits externally into the vertical wall 4 on the L side of While fitted onto the vertical wall 4.63, it is fixed onto the slope by means of stakes 67 inserted into circular holes 66 in the substrate 65.

The upper part of the rectangular part gradually becomes wider towards the bottom, so even if the upper part is tightened just a little, a large gap will be created between the soil and the main frame material. By partitioning, the soil on one side of the weir plate will not move below the weir plate, and it is possible to prevent a large gap from forming between the upper part and the main frame material.

The reason why it fell on the triangular part above the weir plate 61 is as follows.
The wood will not be collected inside the main frame material through the connector, but since the area of this part is small, there will be no excessive amount of wood seeping into the slope.

(Effects of the Wooden Invention) The 11-point drainage-free frame for collapsing on a slope of the present invention constructed as described above can effectively prevent the first collapse of a slope from occurring. In addition to the same effect as the invention, when buried on a slope, there will be no large gap between the frame and the soil, and there will be cuts in the roots that grow on the slope, giving an unnatural feeling. Never.
