retaining overflow dam structure

Abstract

The invention discloses a retaining overflow dam structure, which belongs to the technical field of design and manufacture of hydraulic structures. The invention provides a retaining overflow dam structure with low requirement on foundation setting, simple construction and low construction cost. The retaining overflow dam structure includes block stones and a mesh permeable framework, the block stones are filled in the mesh permeable skeleton, and the retaining overflow dam structure is fixed on the mesh through the mesh permeable skeleton In the river channel or channel where the retaining overflow dam structure needs to be installed on the outside; the water flowing along the channel or channel flows through the gap between the mesh permeable framework and adjacent stones and flows through the retaining overflow The dam structure, the solid matter or displacement substance trapped in the water flow is filtered through the intercepting overflow dam structure and blocked on the water-facing side of the retaining overflow dam structure.

Description

technical field [0001] The invention relates to a retaining overflow dam structure, which belongs to the technical field of design and manufacture of hydraulic structures. Background technique [0002] In rivers and ditches with a lot of moving matter or mud-rock flow, in order to prevent the solid matter in the moving matter or mud-rock flow from entering downstream buildings, or to block the mud-rock flow channel, in order to achieve the purpose of reducing potential and returning to silt, it is necessary to Set up dams. The feature of the retaining dam is that it can not only block moving matter or solid matter, but the dam body is also permeable, and at the same time, excess water flow can overflow from the crest of the dam. [0003] At present, in order to achieve this purpose, retaining concrete dams are generally used in engineering, and permeable holes are arranged on the dam body to reduce the pressure of the dam body, and a comb structure is arranged on the dam cr...

Problems solved by technology

Because it is a concrete structure, it has high requirements on the river channel, channel and the foundation on both banks, so it needs to be excavated, which will damage the original channel and channel, and increase the displacement or solid matter; the concrete dam is a rigid structure, which is less affected by the deformation of the foundation. Large, easily deformed and damaged; concrete dams cannot be obtained locally, the construction is complicated, the construction time is long, and the cost is high.
