Abstract

The invention provides a hydraulic power self-stabilization type underwater construction cofferdam. The cofferdam is formed by splicing a plurality of water stop modules. Each water stop module comprises a baffle and a rubber bottom plate, wherein a steel pressing plate is arranged on the periphery of the upper portion of the rubber bottom plate, the rubber bottom plate is internally provided witha plurality of ventilation holes, a steel plate combined structure is adopted in the baffle, the baffle is internally provided with a plurality of transverse steel beams and a plurality of vertical air guiding pipes, and the top of the baffle is provided with air guiding holes. The upper ends of the air guiding pipes are connected to the air guiding holes, and the lower ends of the air guiding pipes communicate with the ventilation holes. A plurality of steel plates are combined and fixed through the transverse steel beams, the bottoms of the baffles are fixed to the rubber bottom plates, andhydraulic telescopic rods are arranged between the steel pressing plates and the upper ends of the baffles. The hydraulic power self-stabilization type underwater construction cofferdam has the beneficial effects that by means of the device, on the premise that normal running of a water delivery channel is not influenced, the temporary construction cofferdam is constructed at the local damage position in a riverway, local repairing and pouring of concrete are finished, the beneficial effects of mobility and convenient mounting and dismounting are achieved, enough structure stability and anti-skid stability are achieved, the repeated utilization performance of the equipment is good, the manufacturing cost is low, and good development space is achieved in future.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a hydraulic self-stabilizing underwater construction cofferdam. Background technique [0002] With the construction and operation of long-distance water transmission projects in our country, water diversion projects have become a necessary way to solve the lack of water resources in northern my country. During the long-term operation of the water delivery channel, due to the influence of geological conditions, water flow, environmental changes and construction quality, etc., after a period of operation, the bank slope and river bottom of the hard protection channel will be damaged to varying degrees. Local cracking, damage and other phenomena will affect the operation safety of the entire river. It is necessary to carry out timely maintenance and reinforcement treatment. However, in order to meet the normal production and living needs of the water receiving...
