Blocking overflow dam structure

Abstract

The invention discloses a blocking overflow dam structure and belongs to the technical field of design and manufacturing of hydraulic structures. The blocking overflow dam structure is low in requirement for infrastructures, simple in construction and low in building manufacturing cost. The blocking overflow dam structure comprises stone blocks and a meshed permeable framework, the stone blocks are arranged in the meshed permeable framework, and the blocking overflow dam structure is fixed in a river way or a ditch where the blocking overflow dam structure needs to be arranged outside through the meshed permeable framework; water flowing along the river way or the ditch permeates gaps between the meshed permeable framework and the adjacent stone blocks so as to flow through the blocking overflow dam structure, and solid matter or bed load mixed in water flow is filtered by the blocking overflow dam structure and is blocked at an upstream face of the blocking 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.
