Description

[Detailed explanation of the invention] In recent years, as the development of mountainous areas has progressed, avalanches on artificial slopes in snowy regions have become more frequent, and this has become a problem.

One of the main causes of avalanches on such artificial slopes is that the heavily uneven natural slopes are cut out and covered with concrete blocks or concrete slopes with less unevenness, so the snow layer on the slopes slides down. It can cause an avalanche.

Therefore, in this invention, block supports are attached to the slope formed from the foundation blocks to increase the unevenness of the slope and create a structure that can easily prevent avalanches.

Traditionally, slopes have strong snow pressure and avalanche prevention piles have been designed with solid structures integrated with the foundation. However, it was confirmed that by installing more avalanche prevention piles on the entire slope, the snow pressure acting on each avalanche prevention pile becomes smaller.

For this reason, even if the foundation block and block support used for slope construction are manufactured separately, the foundation block is installed, and the block support is integrated into one with a simple installation structure, it is sufficient to withstand slope snow pressure. Confirmed to be durable.

If the block support is integrally molded into the block main body from the time of manufacture, it would be extremely difficult to mold, transport, and install the block since it is an irregularly shaped block with convex portions. For this reason, the convex block of the present invention has a flat block main body and a prismatic block support that are separated, molded separately, and transported.
It has a mounting structure that allows for easy installation and other work.

To explain the convex block of the present invention with reference to the accompanying drawings, Fig. 1 shows a side view of the convex block of the present invention constructed on the entire slope, and in the figure G is the slope, and the surface of this slope G is Flat foundation block 1
This is a construction drawing of a slope construction method in which the block supports 2 are integrated after installation and the block supports 2 are constructed so that the block supports 2 are scattered on the slope.

The convex block of the present invention used in this construction is assembled into one piece by bonding a prismatic block support 2 to the center of a flat foundation block 1 with an adhesive 4, as shown in Figures 2 and below. By using such a convex block, it is possible to prevent avalanches from sliding down slopes. In the structure shown in FIG. 3, a hole 1' is formed in the center of the basic block body 1, and a separately formed block support 2 is fitted into this hole 1' and assembled into one piece. Furthermore, what is shown in FIG. 4 is a convex block according to another embodiment, in which a block support 2 having a separately formed hem 2' is disposed in the center of the basic block body 1, and this hem 2' is secured by bolts 3. The block support 2 is integrally implanted into the foundation block body 1 through the base block body 1. The material of the foundation block 1 and block support 2 used in the present invention may be concrete, steel, or synthetic resin.

5 and 6 are plan views of the convex block of the present invention, and the shape of the basic block 1 may be square or cross-shaped as shown in the figures.

Although the convex block of the present invention has been explained above, it has been confirmed in previous studies that the snow pressure on the slope is greatly affected by the snow depth or the pile height. It has been found that even if the block support 2 is installed with a height that takes snow pressure into consideration, it can withstand snow pressure and is sufficiently effective in preventing avalanches.

By attaching separately molded block supports 2 to the blocks 1 used for slope construction as described above, avalanche prevention on artificial slopes can be easily achieved. The practical effect of using it is great.
