A joint water stop device between aqueducts for water conservancy projects

Abstract

The invention discloses a water-stopping device for joints between aqueducts used in water conservancy projects. On the side of the aqueduct body, the external block is fixedly connected to the outer surface of the aqueduct body, the pillar is fixedly connected to the back of the middle part of the external block, and the inner wall of the aqueduct body is fixedly connected with a waterproof frame. When the aqueduct joint water-stopping device used in water conservancy projects is in use, the combination of the aqueduct body and the external block and other structures achieves the effect of easy installation, and the combination of hydraulic cylinders and telescopic rods achieves accurate water-stopping. Through the combined use of structures such as convex discs and connecting rods, the effect of circular cleaning is achieved, and through the combined use of structures such as bracket rods and arc-shaped cleaning blocks, the effect of sufficient wiping is achieved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a water-stopping device for joints between aqueducts used in water conservancy engineering. Background technique [0002] Aqueducts refer to overhead water tanks that transport channel water across rivers, valleys, depressions and roads. They are generally used for irrigation and water delivery, as well as for flood and sand discharge. Large aqueducts can also be used for navigation. Aqueducts are mainly made of masonry, concrete and Reinforced concrete and other materials are built. As a detailed structure, the seam sealing member is related to the success or failure of the aqueduct design. The commonly used joint water sealing forms of the aqueduct include the middle lap joint embedded type, adhesive type, caulking butt joint type and compression type. For slab type, etc., the joints between adjacent spans of the aqueduct need to be provided wi...

Problems solved by technology

[0003] Aqueducts to transport water sources have been widely used in foundation pits of subways and large-scale housing construction projects, but the concrete joints of the ground connection wall are a weak link in the construction process. The formation of seepage channels causes water leakage at the joints after excavation of the foundation pit, which poses a great safety hazard. In addition, the traditional underground diaphragm wall joint water-stop structure is complex in structure and cannot be prefabricated in advance, which is not convenient for construction and installation, resulting in The construction is difficult, which seriously affects the construction efficiency and prolongs the construction period. In particular, the special material of the inner wall of the existing water stop device will cause a large amount of impurities to adhere to it under long-term use. This situation will not only affect the aqueduct transportation Moreover, if these impurities are not dealt with in time, they will affect the service life and safety of the water stop device and pose a threat to water source transportation. If manual cleaning is used, the aqueduct needs to be dismantled, which will not only affect the transportation project, but also bring The staff caused a lot of trouble
