Abstract

PURPOSE:To easily install blocks produced in a factory on site by a method in which the nearly central parts of an uprising wall and an inclined wall are connected with a connecting wall to form a nearly trapezoidal side structure and coupling portions are provided on the upper and lower ends of the connecting wall. CONSTITUTION:An uprising wall 2 of a plate form, having small holes 7 through which water is drained and small pebbles are charged, and an inclined wall 4 connected with a connecting wall 3 at a proper interval from the back of the uprising wall 2 are integrally formed by reinforced concrete. Also, concaved and convexed portions 5 and 6 capable of vertically connecting sheathing blocks 1 are provided on the upper and lower ends of the connecting wall 3. By this, since, in constructing a sheathing wall 8, blocks produced in a factory can be delivered to a construction site and easily installed by being stacked up in the order of sizes, the period and cost of the construction can be more shortened and reduced than in the case of the conventional stone masonry work.

Description

[Detailed description of the invention] The present invention relates to a top stop block.

Traditionally, stone masonry, reinforced concrete walls, etc. have been used for earth-retaining walls, river agricultural products, etc., but these are all constructed on-site, but after forming the formwork on-site, reinforcing and concrete pouring are carried out. Therefore, there were drawbacks such as a long construction period, high construction costs, and difficulty in construction management.

Therefore, the present invention has been developed in view of the above-mentioned drawbacks of the conventional art, and as a result, a new stopper block has been developed. The objective is to shorten the construction period and reduce construction costs, and also to be extremely stable against slipping and shearing forces, and to be able to be installed with the front face vertically, thereby minimizing land loss.

The present invention will be described below in detail based on the illustrated embodiment. As shown in FIG. It is integrally formed of chestnut stone or reinforced concrete with a sloped wall (4) connected to the back by a plate-shaped connecting wall (3) at an appropriate interval, and the connecting wall (3) The upper end and the lower end are respectively provided with a concave part (5) and a convex part (6) for connecting the top stop block (1) in the vertical direction, and are further connected to the upright wall (2) and the inclined part. The walls (4) are each provided with small holes (7) for draining water and for introducing small particles.

Here, the inclined wall (4) is inclined outward from the upper end to the lower end with respect to the upright wall (2), and the upper stop block (
1) is formed to have a substantially trapezoidal side surface to enable stable installation, and a connecting wall (3) connects the approximately central portion of the upright wall (2) and the inclined wall (4) at the butt.

That is, the front and back (1) have the following features:
The widths of the upper and lower ends are the same, and on the sides, the upper end has a smaller dimension t, while the lower end has a larger dimension.

Also, construct a retaining wall (8) using the same block (1) as shown in FIGS. 2 and 3 - the above-mentioned dimension t of the moss.

A large number of items with different L values are prepared.

In order to make it possible to sequentially stack the blocks (1 tv1 each block), a large number of blocks with different dimensions tsL are set and formed.

Furthermore, the top stop block +11 has an upright wall (2) and an inclined wall (
4) In between, a space a convenient for putting chestnut stone (crushed stone) is provided on both left and right sides of the connecting wall (3), with openings at both upper and lower ends and one side.

In the above configuration, when constructing the earth retaining wall (8) using this, as shown in Fig. 2 and Fig. Among the top blocks (1) fil'fi+', which have been formed in accordance with the stackable L scale dimension t%L, the block +11 with the maximum dimension is installed on the foundation rubble part (9). wear.

A drain pipe 01 is buried at the lowest part of the foundation rubble section (9) above.

The second stage block (1)' is superimposed on the lowermost block (1) installed as above, and the four joining parts (5) and convex part (6) are engaged and mutually connected. Then perform front-to-back and left-right alignment, and stack l pieces at a predetermined position.

In this way, the third (top in the example shown) block (1)' is stacked on top of the second block (1)', but at this time, the back of the valley slope wall (4) is is composed of Kuriteki layer (III) for water collection, and each block is 111 tll.
'(11' ffi, toe 9 space, e, as tc
F1 chestnut stone aa (crushed stone) is filled as shown in FIG. 3, and sliding and shearing forces are resisted by this and the basic rubble layer (9).

Furthermore, the top of the top step can be sealed with cast-in-place concrete 0, as shown in Fig. 4, (B), and lc'l, or the bottom wall A4 can be sealed with concrete as shown in UB. It is preferable to form it and use it as a button 15, or furthermore, as shown in C, apply soil and plant a tree.

In addition, in Fig. 2 and M3, α71Fi drainage culvert, a [with] indicates loess.

As explained above, the top stop block according to the present invention includes a plate-shaped upright wall (2) and a plate-shaped connecting wall ( It is integrally formed with an inclined wall (4) with a small hole (7) connected at 3), and blocks can be stacked vertically on both the upper and lower ends of the connecting wall (3). Since it is constructed by providing a fitting part for joining with a concave part (5) and a convex part (6), when constructing the earthen wall (8), the materials brought to the site are stacked in order of size. Since it can be easily installed, the construction period and cost can be greatly shortened and reduced compared to conventional masonry, cast-in-place concrete, or even the construction of a four-block earth retaining wall.

In addition, you can use chestnut stone to increase the width of the legs, as well as create an upright wall (
Since the space a between 2) and the slope 11 [4] can be filled with chestnut stone a3, the shearing force of the chestnut stone n will resist the mutual sliding of the blocks.1 The leg width can be increased as described above.11 Small holes (7) in the upright wall (2) and inclined wall (4)...
11 and a sloped wall (4) on the back, this prevents deterioration of the soil quality due to water in the ground and prevents horizontalization due to water pressure.This combination creates an extremely stable earth-retaining wall. can be constructed.

Furthermore, the front WJ is secured by the earth retaining wall (8) and the F1% upright wall (2).
Since it can be constructed vertically, the loss of land can be minimized, and furthermore, it can be manufactured in a factory and mass produced, so it can be provided at low cost.
