Problems solved by technology

[0002] Slope dams are generally used in plateau soil and water conservation check dam projects, highway construction and ground restoration projects in open-pit mining areas, but: (1) In soil and water conservation dam projects, the cost of dam construction is high, and large civil engineering equipment is required. The dam is impermeable, the dam site cannot prevent floods and ensure income, the salinization is serious, and the utilization rate of the dam site is very low. The gully dam system is bound to store a large amount of natural precipitation, which seriously affects the downstream flow, resulting in longer and longer downstream cut-off times; ( 2) In the construction of highways, especially expressways, the average construction cost per kilometer reaches tens of millions, or even hundreds of millions of yuan. Among them, the three items of earthwork (roadbed), side slope and flood drainage network are not only expensive, but also time-consuming; (3) In the ground restoration project of the open-pit mining area, the waste ore filling layer and the artificial topsoil layer have a large area, and the artificially accumulated topsoil is very easy to be lost or leached, so that the vegetation recovery is slow

Abstract

This is an installation of side slope dam; it is composed with two or more layers of sand bags. Between the two sands bags and the two layer of it, there are connected by button, on the two sides of the button there are convex thorn, it can be plugged into the sand bags. Then this construction secures the dam stability.
