A self-controlled rubber dam with wear-resistant steel plates

Abstract

A self-controlled type rubber dam with a wear-resistant steel plate comprises a reinforced concrete groove, a rubber dam body anchored to a bottom plate of the groove, and a water supply and drainage pipeline arranged from the upstream side to the downstream side. The wear-resistant steel plate with a hinge support is arranged above the groove. A hinge supporting base is arranged between the wear-resistant steel plate and a step on the upstream side of the groove. A roller is arranged at the tail end of the downstream side of the wear-resistant steel plate. A separated channel is arranged in a riverbed between the groove and the water drainage section of the downstream side of the water supply and drainage pipeline. An anti-sliding ridge is arranged in the separated channel. Water stop rubber is arranged below the anti-sliding ridge and connected with a floating ball on the water surface through a lacing. The rubber dam body supports the wear-resistant steel plate to stop water and does not make contact with water current directly, abrasion and impact to bed load sand grains are avoided, the structure is simple, and construction is easy and convenient. In the flood period, the rubber dam body collapses into the groove, the wear-resistant steel plate directly serves as a groove cover plate after falling off so as to protect the rubber dam body and prevent silt. Meanwhile, a floating ball system of the rubber dam can automatically regulate the rubber dam body for sluicing.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and relates to a water-retaining (water-discharging) structure that can be adjusted with seasonal low water / high water—a self-controlled rubber dam with wear-resistant steel plates. [0002] In this invention, when the water level in the downstream of the river is low in the dry season, the water pump and the water inlet valve are manually opened, and the floating ball linkage device is used to automatically close the water outlet valve to fill the rubber dam with water to lift the anti-wear steel dam to retain water; when the water level in the downstream is high , the water outlet valve is automatically opened, and the water pump is turned off to release the water filled inside the water tank so that the rubber dam and the wear-resistant steel plate fall down to drain the water. Background technique [0003] The annual runoff of rivers in mountainous areas in southern my country is ...

Problems solved by technology

The invention not only has the advantages of low cost, short construction period, convenient management, and less impact on the original ecology of the river, but also makes up for the fact that the existing rubber dam is prone to abrasive damage under the long-term erosion of the river containing mass.
