Anti-seepage structure for deformation joint of concrete structure and construction technology of anti-seepage structure

Abstract

The anti-seepage structure comprises two pieces of concrete and a deformation joint body, low-pressure inserting grooves are formed in the two pieces of concrete, high-pressure inserting grooves are formed in the two pieces of concrete, and an anti-seepage bottom plate is fixedly installed at the bottom of an inner cavity of the deformation joint body; rubber strips A are fixedly mounted on the two sides of the anti-seepage bottom plate correspondingly, and an anti-seepage partition plate layer is mounted in the deformation joint body. Through rotation of an arranged threaded rod, under limiting of a threaded hole, the threaded rod moves downwards, so that a circular truncated cone top block is driven to move downwards, the circular truncated cone top block finally moves to the inner side, an insertion rod is jacked and pressed, the insertion rod is inserted into two pieces of concrete, the anti-seepage partition plate layer is installed in the deformation joint body, the installation effect is good, and the practicability is high. Installation is simple, the anti-seepage partition plate layer cannot move downwards or upwards after being installed, and therefore the filling effect of an anti-seepage agent and a non-curing material is guaranteed, and the anti-seepage effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and particularly relates to an anti-seepage structure for a deformation joint of a concrete structure and a construction process thereof. Background technique [0002] With the rapid development of society, more and more new large-scale and large-scale buildings are being built continuously. Because the buildings are too large, considering the influence of factors such as expansion, settlement and earthquake resistance, reserved deformation is adopted in the design. However, due to factors such as technology, design, material, construction and cost, the waterproofing of deformation joints has become a weak link. It is very easy to leak, almost nine leaks out of ten seams. The deformation joint seeps and leaks, causing black and moldy on both sides of the joint due to water seepage and water leakage pollution, which affects the beauty and function of the building, and will affect...

Problems solved by technology

The disadvantage is that when the water-swelling consolidated body loses water for a long time, it will also lose water and shrink, and the shrinking consolidated body will not swell when it encounters water again or the swelling rate is insufficient, which will most likely lead to the loss of waterproof effect And "relapse"
