Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to earth retaining walls, greening retaining walls, coasts, lakes, and marshes on slopes such as roads, residential lands, and parks.

2. Description of the Related Art A conventional earth retaining wall is constructed by sequentially stacking and installing T-type or H-type wall blocks having a horizontal sectional shape on a foundation block fixed on the ground.
Backfill embankment is applied several times in the space between the cut end surface of the sloped land and the block wall. In a general block-retaining wall, connection between adjacent wall blocks is performed by engaging concave and convex portions on a joint end surface, and this engagement state is maintained by the weight of the wall block itself.

In order to withstand the earth pressure from the inclined surface and secure the connection between the wall blocks, it is necessary to design the wall blocks to have a large weight. Excessive weight increases the labor burden on the workers during the pile-up work. Let it.

[0004] In order to reduce the labor burden at the time of construction, it is also possible to provide a cavity part penetrating in the vertical direction in the wall block, and to pour concrete into the cavity after stacking to secure a required composite weight. Is being done. In this wall structure, the upper and lower wall blocks are integrally connected to each other through the buried concrete, so that a strong wall structure can be obtained. The construction conditions are greatly restricted by weather conditions such as the above, and the construction period is often forced to be delayed, and the casting work requires a large amount of manpower, which also increases labor costs.

[0005] On the other hand, in a curved portion that is concave or convex with respect to the road, the wall blocks adjacent to the left and right are arranged in a series so as to draw a polygonal line as close as possible to the curve. A triangular space is formed in plan view between the rectangular parallelepiped front slabs butted with each other at the vertical ridges on the rear end side. Are likely to have cuts or gaps that are exposed on the back side, and this will damage the wall surface.

If the scratch is left as it is, not only does the appearance of the wall surface of the block pile deteriorate, but also it becomes an outlet for the filling material or backfill material of the block pile wall. It is filled with mortar or concrete, or has a flaw-filling block that fits the three-dimensional shape of the space.

[0007] However, in the system using the block for flaw compensation, it is necessary to prepare and prepare another type of dedicated block corresponding to various curved surfaces having different radii of curvature, so that the cost increases. In addition, in the method of filling mortar or concrete, the work efficiency is poor because the work is easily affected by the weather, and when the filled mortar or concrete peels and falls, the appearance appearance is rather deteriorated.

[0008]

Further, another object of the present invention is to provide a wall surface in which adjacent wall blocks are firmly connected to each other without increasing the weight of the wall blocks, so that an assembling operation can be performed efficiently with a reduced labor load. Is to provide a block.

Another object of the present invention is to provide a wall block capable of efficiently connecting a base block, a wall block and wall blocks.

Another object of the present invention is to provide a wall block capable of accurately constructing a wall surface without damage between the front slabs of the wall blocks adjacent on the left and right.
