Aqueduct for water conservancy project

Abstract

The invention provides an aqueduct for a water conservancy project. The aqueduct for the water conservancy project comprises an ethylene-propylene-diene monomer composite GB water-stop belt, a stainless steel pressing plate, GB flexible water-stop plates and a shield. The ethylene-propylene-diene monomer composite GB water-stop belt is fixed onto an expansion joint through the stainless steel pressing plate with the thickness being 4 mm; polymer mortar is further filled into the top part of the stainless steel pressing plate in a slot; a layer of PCS flexible waterproof coating is coated on the surface of the polymer mortar; the shield is fixed to the outer surface of the PCS flexible waterproof coating through expansion bolts; sealing cushions are inlaid to the two ends of the bottom sideof the shield; and a filter screen is inlaid in the middle of two ends of the shield. A gap between a first pressing plate and a second pressing plate on the stainless steel pressing plate can adaptto expansion deformation of the expansion joint, the rubber cushions can prevent the gap between the first pressing plate and the second pressing plate from leaking water, the GB flexible water-stop plates are filled on the polymer mortar so as to adapt to the deformation of the expansion joint, and by arranging the shield, the service life of the PCS flexible waterproof coating and the polymer mortar is prolonged.

Description

technical field [0001] The invention belongs to the technical field of hydraulic engineering, in particular to an aqueduct used in hydraulic engineering. Background technique [0002] An aqueduct is an overhead water delivery structure that transports channel water across river canals, roads, mountain rushes, valley mouths, etc. It is one of the most widely used intersecting buildings in canal systems. In addition to water, industrial water, and cross-basin water transfer, it can also be used for drainage and diversion. [0003] The inventor found similar patents on aqueducts in the process of searching for patents. For example, in the Chinese patent application number: 201520230739.1, a water-stopping structure for aqueducts with embedded grooves is disclosed, including rubber waterstops 1, There is a U-shaped structure 11 on the rubber waterstop 1, and the water-facing surface 12 of the rubber waterstop 1 is sealed with acrylic milk mortar block 7. On the back surface 10 ...

AI Technical Summary

Problems solved by technology

[0005] Based on the above, the inventors found that the anti-seepage and anti-leakage or water-stop strips at the expansion joints of the above-mentioned aqueduct are prone to problems such as corrosion and aging under the long-term erosion of water flow, and the service life is reduced. Only one anti-seepage and anti-leakage strip is used. structure, after the anti-seepage and anti-leakage structure or the water-stop strip is damaged, leakage is prone to occur at the expansion joints of the aqueduct
