Abstract

PURPOSE:To shorten the period of construction, reduce the cost of construction, and keep strength standard constant by using an integrated structure attached with a housing body to house back-filling material in the back side of a block or retaining wall by projection coupling or bolt clamping. CONSTITUTION:Plate projections 3 with through holes 7 are provided to the four corners of the back 2 of a block 1, and hooked projections 4 are provided to the front side of a housing body 6 to house back-filling material, consisting of a square plate with many latticed through holes 5 and a bottom part. The projections 4 are pierced through the holes 3 of the projections 3 and the body 6 is attached to the block 1 to form and integrated structure. In almost the same way, the body 6 may be attached to a retaining wall 8 and female screws may be used for the projections 3 and 4. The body 6 is packed with a back- filling material and connected to the upside of a base concrete in vertical and horizontal rows to stack up them.

Description

[Detailed Description of the Invention] C Industrial Field of Application] This invention is a retaining wall rear storage framework in fS retaining wall work in which a storage framework for storing backfilling material on the back side of a block and #I wall is integrated into an f1 structure. Between the two construction methods.

[Conventional technology]

It was laid by stacking blocks of chestnut stone and cut gravel. For the retaining wall, chestnut stone and cut gravel are used as a drainage layer between the back ground and the retaining wall to form a layer, and during construction or professional construction, the layer is laid after leveling the back fill. . In retaining wall construction, a backfill village is inserted between the other mountain and the retaining wall, and the work process is separate, so the work is subdivided and the backfilling material is only used for drainage purposes, and the purification effect of the drainage water is not achieved. [Problems to be resolved by the invention] The present invention has the following points: a backfill village is simply laid between another mountain and a block, and a retaining wall is also installed between the backfill wall and the slope of the ground as described above. Filling material was placed directly in the backfill material, but due to the reduction in the pores of the backfill material, the drainage effect was reduced, allowing surface water to permeate, causing ground water to accumulate in the backfill material and stagnate. The point where the upper part of the wall is damaged. The construction process involves separate blocks and retaining wall backfilling and filling processes.

, The construction of the Heme Village directly creates a drainage layer between the ground and the structure. The point at which the pores in the drainage layer decrease due to natural pressure in later years and the drainage layer becomes hollow due to the pores.

The purpose is to provide a solution to the fragmentation of 3 work processes in which surface water and underground water are discharged without being purified.

[Means for solving problems]

This invention is designed to attach the backfill material that serves as a drainage layer provided on the block and retaining wall ground and slope to the back of the block and retaining wall. The storage frame with integrated hook protrusions is joined with the protrusion to create an integral structure, and the storage frame is aligned with the female screw holes provided at the four corners of the back of the retaining wall, and then aligned through the through-hole of the storage frame and integrated. By making it into an integrated structure, the ]-shaped protrusions installed in a straight line at the two corners of the block and the back of the retaining wall were fitted into the recesses of the U-shaped protrusions installed in a straight line at the two corners of the storage frame. charcoal,
Lime blocks, permeable ceramics, and filtration materials are mixed with conventional backfilling materials such as chestnut stone and cut gravel in a ratio of 5:6 or more to alleviate drainage. A hook protrusion 4 bent at right angles toward the bottom is integrally attached to the front side of a storage frame 6 whose four sides and the bottom are covered with a grid-shaped through hole 5, and a plate-shaped protrusion of the block 1. 3 is an explanatory diagram for attaching the protrusions 4 to the through hole 7 in the center of the block 1 as a structure; in the state shown in FIG. In contrast to 3, the rear side of the storage frame 6 in contact with the slope surface corresponds to the slope of the slope, speeding up the construction work, and since the storage frame forms a drainage layer, the block and barrier become a single structure, allowing for natural rotation of the drainage layer. This is a construction method that prevents pressure, blocks, and the back of the retaining wall from becoming hollow.

〔Example〕

The method of constructing a retaining wall with a rear storage frame according to the present invention will be explained based on the drawings. Fig. 1 shows plate-shaped protrusions 3 having a constant width and thickness at the four corners of the vertical surface of the rear surface 2 of the block 1. Through hole 7
This is an explanatory drawing using the retaining wall 8 that is inserted into the wall and made into a single structure.
Figure 3 shows that the front side of the storage frame 6 consisting of the west side body is aligned with the female screw holes at the four corners of the back of the block 1, and the bolts 10 are inserted through the circular through holes 9 of the storage frame 6 into the female screw holes at the four corners. Although it is not shown in the drawings, the retaining wall is of course an integral structure with screws attached to the top of the wall. Fourth
The figure shows a block 1 in which 1-shaped protrusions 11 are linearly integrated into the two corners of the back surface 2 of the block 1. The side surface is made of a four-sided body, and the two front corners of the side surface are made of through-holes 5 with a lattice-shaped bottom surface. 1 on the back of the block 1 on the storage frame 6 having the U-shaped protrusion 12.
It is a theory that the retaining wall will have a similar structure by inserting the protrusion 11 into the recess 13 at the center of the U-shaped protrusion 12 and integrating it. Figure 5 shows professional construction using conventional general construction.
Construction work using Tsukunori lining begins with cutting out the ground 14 and pouring foundation concrete 16 on the chestnut stone foundation 15. After that, the backing of the ground 14 is carried out on the slope surface to alleviate rainwater, drain it, and store it. By stacking the building blocks 6 individually in vertical and horizontal rows to form layers depending on the state of connection and connection, the backfilling material 17 is prevented from becoming compacted later and creating a cavity on the back surface, and the upper part is covered with the crown concrete 18. The work process stops at , and the point that the process can be shortened as described above is that the backfill material work and the block construction work are performed in the same process, resulting in a reduction in the number of work process days. FIG. 7 shows the retaining wall 8 viewed from the front and showing the process in which the west side body integrated on the back side is formed with lattice-shaped through holes 5. The process of constructing a slope on the ground mass 14 and pouring the foundation concrete 16 on the chestnut stone foundation 15 is the same as the conventional process, but the storage frame 6 is formed on the foundation concrete 16 by the protrusions and holes on the back of the block 1. The charcoal, lime block, permeable ceramics, and filtration material that will become the backfilling material 17 can be mixed with chestnut stone and cut gravel in a ratio of 5:6 in the storage frame 6, or they can be directly added individually to surface water, underground. After pouring water and acidic foundation concrete 16, a retaining wall 8 was installed, and the circular through-hole of the storage frame 6 and the female screw 6 of the retaining wall 8 were aligned, and they were tightened with bolts 10, resulting in the storage frame 6 becoming an integrated structure. After a backfilling material 17 is inserted inside the retaining wall 8, underground water from the ground at the back and seepage water from rainfall are drained from the drain hole 19 of the retaining wall 8. Figure 8 shows the installation of a storage structure 6 on the back of a block 1 on a mountain slope 21 during the construction of a river 20 embankment with no adhesive.
By using the construction method with a retaining wall storage frame that incorporates the backfill material 17, the drainage layer consisting of the block 1 and the backfill material 17 can be constructed in the same work process as the block 1 installation, and the hole 22 in the front of the block 1 The block 1 becomes a fish nest, and the structure of the block 1 allows it to be installed in a variety of ways, and the structure of connecting it to the retaining wall 8 can of course be made up of the two methods described above.

〔Effect of the invention〕

Although this invention is constructed as described above, it is possible to reduce the total number of storage frames by attaching the storage frame to the back of the block and retaining wall, and to reduce the construction cost by limiting the number of holes in the backfill village. The joint structure consists of a joint structure between protrusions and a bolt-fastening structure using the conventionally known fastening method, which shortens the construction period, reduces the labor required for special upholstery work by a stone mason, and allows ordinary workers to do the work. The material and labor costs required for construction are reduced, and the blocks and retaining walls made of brush cast products ensure stable product strength, ensuring perfect quality control. Similarly, the storage frame can also be constructed with a drainage layer in one operation. The backfilling material that forms the drainage layer can be used by mixing charcoal, limestone, permeable ceramics, and filtering materials with conventional chestnut stone and cut gravel in a ratio of 5:6, or by using them individually to prevent acid rain and acidic soil. The purpose of this project is to alleviate water leakage, and the water permeability of the backfilling material contained within the housing structure is not limited to just the drainage effect, but the drainage layer on the back is It is possible to maintain a constant strength standard that prevents clogging and damage caused by hollowing of the drainage layer and freezing damage in winter due to stagnant water.Of course, the material of the storage frame can be made of a variety of materials depending on the purpose of use. be.
