Problems solved by technology

[0004] However, in the case of using the former method of making concrete bricks, there is a problem that high construction costs are required. In addition, in the case of using the latter technology of foamed polystyrene, since the foamed polystyrene itself is expensive, construction is difficult. The cost becomes relatively high, and due to the light weight of foamed polystyrene, there are disadvantages of poor safety, and it is difficult to popularize it generally.

Embodiment 1

[0043] Figure 1~ Figure 4 Shown A is the soil-proof and solid wall of the present invention in Example 1. The soil-proof and solid wall A is laid with a base round stone layer 1 at the solid wall construction site B, and a synthetic resin foundation is laid on the base round stone layer 1. Adjust the block section 2, pile up bricks 19 on the foundation adjustment block section 2, construct the solid wall main body 3, and set the protective wall body 4 in front of the solid wall main body 3 at the same time. 5 is backing crushed stone, 6 is backing Soil, 7 is filter material, 8 is perforated pipe, 9 is upper drainage pipe, 10 is lower drainage pipe, 11 is coated board, 12 is top concrete, 13 is pavement layer, C is bedrock, 14 is The legal surface formed by excavating the bedrock C.

[0044] In addition, as shown in FIG. 5 , the solid wall main body 3 is formed of a block 20 for forming the front wall, and a plate that is placed in a substantially horizontal state by engaging...

Embodiment 2

[0061] Figure 13 and Figure 14 It shows the soil-proof and solid-wall A as Example 2, which constitutes the basic structure of the soil-proof and solid-wall A in the same way as the soil-proof and solid-wall A of the above-mentioned Example 1, except that the plate-shaped block section 21 is divided into two parts to form .

[0062] That is, as shown in FIG. 15 , the plate-like block 21 is formed by a front block forming piece 40 and a rear block forming piece 41 detachably connected to the rear end of the front block forming piece 40 . .

[0063] In addition, the front block forming sheet 40 is formed by forming the block forming sheet main body 40a into a thin plate shape with a foamed resin such as polystyrene foam, and forming two vertically penetrating bars on the left and right center lines of the block forming sheet main body 40a. Communication holes 43, 43 are spaced at a certain interval in the front-rear direction, semicircular arc-shaped communication hole formin...

Embodiment 3

[0071] Figure 16 ~ Figure 18 It shows the soil-proof and solid-wall A as embodiment 3, and the soil-proof and solid-wall A forms the same basic structure as the soil-proof and solid-wall A of the above-mentioned embodiment 1 and embodiment 2, but the solid-wall main body 3 is different in the following aspects . 15 is the contour line of the bedrock C before forming the legal face 14 .

[0072] That is to say, the solid wall main body 3 is formed by stacking bricks 19 formed by combining basic block sections 60 and half-cracked block sections 61 .

[0073] In addition, the basic block 60 has a pair of front and rear longitudinal walls 64, 65 and a pair of front and rear longitudinal walls 64, 65 that pass through the vertical longitudinal holes 62, 63 through foam resin such as foamed polystyrene, and are erected at the center of the two longitudinal walls 64, 65. Between the parts, there is a communication hole 66 penetrating in the vertical direction in the central part, ...

Abstract

Laying blocks are stacked one upon another with communication holes passing vertically through the laying blocks formed therethrough, earth and sand are filled in gaps between upper and lower ends of the laying blocks, as well as in communication holes to join vertically earth and sand in each layer, a block protection wall is erected in front of stacked laying blocks, and a filler is filled in a gap between the rear surface of the block protection wall and the front surfaces of the stacked laying blocks, thereby ensuring a stable function as a retaining wall and reducing construction costs.

Description

technical field [0001] The present invention relates to a soil-proof and wall-retaining structure capable of reducing construction costs while ensuring a good stabilizing function as a wall. Background technique [0002] In the past, as a form of soil-proof walls, concrete bricks were stacked and constructed. In this soil-proof wall, the back soil pressure acting on the wall was calculated, and then the resistance to the back soil pressure was calculated. The thickness of the pressed solid wall and the amount of steel bars are used for construction. [0003] In addition, in recent years, a process has been developed to replace the solid wall sand that produces the back earth pressure with foamed polystyrene. In this process, since the sand and the replaced foamed polystyrene are so light that they can be ignored, if the All the sand and soil on the angle of repose can be replaced, which can eliminate the back soil pressure acting on the reinforcement wall. At the same time,...
