Description

Rhombic dam using light weight steel and rock}

The present invention relates to a technology for effectively preventing the flow of earth and soil while the rapids occurring in the valleys, and in particular, widening the passage area of the four-side dam and preserving the natural ecosystem while maintaining a smooth flow of the downstream.

In general, in valleys with large river gradients, rapids dug up riverbeds and cut off both foothills to cause landslides. The dam will be built.

In addition to this purpose, by installing four dams in rivers and valleys, the water stored by the four dams can be used in various ways. For example, it can be used as a water source for extinguishing wildfires in case of wildfires, fish farms, a reservoir for agricultural water supplying farmhouses during droughts, and a safe water play area in summer.

However, most of the conventional four-sided dam is constrained according to site conditions because the site work is increased by constructing the concrete structure. The biggest constraint among these is that it is difficult for concrete mixer trucks to enter the construction site at the foot of the mountain. In order to install the four-side dam at the foot of the mountain, an on-site mixer has to be used. It has the disadvantage of causing.

Even if the concrete mixer truck is easily accessible, even in the construction site, additional equipment such as formwork for concrete placement is required, and there is a disadvantage in that the overall construction period is lengthened by increasing the number of field works.

As a solution to some of these problems, "Patent Application No. 2002-52058, Construction method of a four-side dam using a name / assembly type frame" has been proposed.

While the above-described prior art provides a useful effect of solving the above-mentioned problems, the occupied area occupied by the screens installed on the front and rear surfaces of the plurality of steel frames constituting the four-side dams is very large, and thus, the leading means for passing through the screens. Due to this narrowness, especially in the dry season, the flow of the flowing water is not smoothly downstream, and there is a wasteland where fish and aquatic plants cannot live on the downstream side of the four sides of the dam.

In addition, since the steel frame is constructed on the ground surface as it is without additional foundation concrete, when rainwater penetrates the ground surface, there is a high possibility of collapse of the four-side dam as the ground subsides, and thus the stability of the structure as a whole is deteriorated.

In addition, the four-sided dam of the prior art was not able to create a natural gorge that maintains the natural ecosystem because the fish can not freely travel up and down the four-side dam because there is no fish passage.

The present invention is to actively solve all the problems of the above-described prior art, the general means area so that the flowing water can pass through the entire area except the occupied area of the wire rope installed on the outer surface of the upper and lower sides of the light steel frame It is a problem of the present invention to secure more widely.

In addition, the present invention is to bury the light steel structure frame on the base concrete placed on the ground to maintain the structural stability of the four-side dam as a problem of the invention.

In addition, through the esophagus provided on the downstream side of the four sides of the dam, the fish can smoothly travel up and down in the dry season as a problem of the invention.

The present invention places the foundation concrete on the ground of the valley as a means for solving the above problems, and embeds a plurality of lightweight steel frame at intervals on the bottom surface of the foundation concrete, stones along the inner surface of the lightweight steel frame It is installed to surround the mesh, and the interior of the gabion is filled with a man-stone, and devises a technique for laying a plurality of wire ropes on the upper and lower sides of the lightweight steel frame at intervals up and down.

According to the present invention, by constructing the four-sided dam quickly and easily by using lightweight steel frame and sandstone, it is excellent in economic efficiency and provides the effect of shortening the air, as well as saving the rapids generated in the valley and can be utilized for various purposes. It provides the effect of preventing the soil from flowing down.

In addition, the entire area except the occupied area of the wire rope installed on the upper and lower outer sides of the lightweight steel structure frame can secure a wider communication area by forming a communication area, so that the smooth flow of flowing water can be maintained even in the dry season. It provides a conservative effect.

In addition, the light steel structure frame is stably embedded on the foundation concrete placed in the valley ground provides an effect that can effectively prevent the ground collapse even if rainwater penetrates to the ground surface to enhance the overall structural stability of the dam.
