Description

Technical Field

[0001] The utility model belongs to the field of cofferdams, in particular to a segmented continuous rubber cofferdam, and particularly relates to the fields of staged riverbed cleaning, temporary water retaining wall construction, etc. Background Art

[0002] Cofferdam is a common temporary construction project in the construction process of water conservancy projects. It can greatly improve the working environment, improve the quality of project construction, provide conditions for the orderly development of various construction processes, and provide guarantees for the quality and safety of the main project construction. The main function of the cofferdam is to prevent water and soil from entering the construction site of the building, so as to drain water, excavate foundation pits, build buildings, etc. in the cofferdam. Therefore, the water retaining and stability of the cofferdam are required to be high. For cofferdams in shallow water areas, the selection and operability of the cofferdam are relatively high because the environmental water level required for the cofferdam is relatively low.

[0003] In the past, the following two types of cofferdams were mainly used in shallow water areas. The first type is an earth cofferdam. The initial construction method is to use a soil truck to pull the soil to the cofferdam filling point and then use an excavator to push and roll the soil from one or both sides to the middle at the same time until it is closed and reaches the designed elevation and width. This method takes a long time to construct, consumes a lot of soil resources, occupies a large area and is only suitable for rivers with a water flow rate of less than 0.5m / s. The second type is an earth bag cofferdam. Its construction method is to first use straw bags, sacks or woven bags to pack the soil and sew the bag mouth. Then stack the earth bags to the corresponding construction position to form an earth bag cofferdam. Although this method can be applied to rivers with higher flow rates than earth cofferdams, it widely uses manual labor, it is difficult to improve work efficiency, and it consumes a lot of physical strength for on-site workers. Like the first method, it consumes a lot of soil resources and is one-time. Utility Model Content

[0007] The wire stringing frame adopts an equilateral triangle structure. The top of the wire stringing frame is provided with a wire stringing hole, and the stringing steel rope passes through the wire stringing hole.

[0008] The water supply system comprises a water inlet pipe connected to the rubber weir body, the water inlet pipe is connected to a weir body water filling pump, and the other end of the weir body water filling pump is connected to a water source through a water supply pipe.

[0009] A weir exhaust hole is arranged at one end of the top of the rubber weir.

[0013] The utility model has the following beneficial effects:
