Problems solved by technology
As mentioned in the previous paragraph, this method has some deficiencies, and if the above-mentioned surface water-stopping method based on rubber rods, elastic waterstops and plastic fillers is directly used, it can solve the problems of embedded waterstops very well. Disadvantages, but there will still be high cost and overkill, because this kind of surface water stop is developed for structures such as concrete face rockfill dams with large displacement, and the relative displacement of joints of structures such as gravity dams is much smaller

The invention provides a water-stop strip, a water-stop structure of the water-stop strip, and a construction method for the water-stop structure. The water-stop strip is made of elastic materials. The whole water-stop strip is in a strip shape and comprises a plug, a left side wing and a right side wall. One end of the left side wing and one end of the right side wing are connected to the second end of the plug. An included angle alpha is formed between the left side wing and the plug. An included angle beta is formed between the right side wing and the plug. A groove seam is formed in the end face of the second end of the plug. In the water-stop structure, the water-stop strip is arranged in a surface seam in an upstream face of a preset object; the plug of the water-stop strip of the water-stop structure is embedded in the surface seam; the left side wing and the right side wing cover the two sides of the surface seam; and the two side wings and the surface of the preset object are bonded through polymer structure glue playing a sealing role so that covering of the surface seam and sealing water stop can be achieved. The water-stop structure can bear the water pressure of a 100m water head and can bear the situation that joints are opened by 2 cm. The water-stop strip is formed at a time through a special mold and is high in quality, low in manufacturing cost, convenient to transport, beneficial to construction and installation. The finally constructed water-stop structure is safe and reliable in water-stop effect and low in expense.
Description
technical field [0001] The invention relates to the field of water conservancy project construction, in particular to a water stop strip, a water stop structure using the water stop strip and a construction method for the water stop structure, which is a rapid construction and reliable hydraulic structure interface. Seam surface waterproof structure and method. Background technique [0002] Due to the characteristics of concrete such as drying shrinkage and temperature stress, the characteristics of the building itself such as uneven deformation, and the limitations of concrete mixing and pouring capabilities, hydraulic concrete buildings are often not poured in one piece, and joints need to be set. For example, expansion joints are set at intervals for concrete aqueducts and canals, transverse joints perpendicular to the dam axis are required for concrete gravity dams, and many horizontal and vertical joints are required for the concrete face of face rockfill dams, all of w...
