Surface precast component structure with water sealing expansion joint and construction method thereof

Abstract

The invention relates to a surface precast component structure with a water sealing expansion joint and a construction method thereof. The structure comprises the expansion joint and building bodies which are located on two sides of the expansion joint, the building bodies are provided with concave parts, and surface precast components are arranged on the concave parts, and the surface precast components comprise first plate surfaces, second plate surfaces, third plate surfaces and fourth plate surfaces which are vertically connected in sequence; fifth plate surfaces are arranged at the tail ends of the fourth plate surfaces, the tail ends of the fifth plate surfaces are located in the building bodies, and first angles are formed between the tail ends of the fifth plate surfaces and the fourth plate surfaces; sixth surfaces are arranged at the tail ends of the first plate surfaces, the tail ends of the sixth plate surfaces are located in the building bodies, and second angles are formed between the tail ends of the sixth plate surfaces and the first plate surfaces; surface water sealing components are arranged on the third plate surfaces and the outer side surface of the expansion joint, and the top surfaces of the surface water sealing components are lower than or as high as the first plate surfaces. According to the surface precast component structure, the precast components can be well combined with concrete, the construction technology is standardized, the final water sealing effect of the expansion joint of a hydraulic structure is greatly improved, and the construction quality and construction effect are improved.

Description

technical field [0001] The invention belongs to the technical field of anti-seepage construction of water conservancy projects, more precisely, it relates to the prefabrication, installation and construction technology of hydraulic concrete expansion joint water-stop structure, and is a prefabricated part of expansion joint surface water-stop that can be constructed quickly and efficiently. structure and its method of construction. Background technique [0002] In the existing hydraulic concrete structures, such as retaining dams, sluices, aqueducts, tunnels and other wading projects, due to the impossibility of continuous pouring or the thermal expansion and contraction of concrete due to temperature changes, it is necessary to leave deformation joints during pouring. For construction joints and other expansion joints, in order to ensure engineering safety and structural functions, water-stopping measures must be taken for expansion joints. Expansion joint waterstop struct...

Problems solved by technology

However, in the current surface water-stopping scheme, there is still a problem that the water-stopping material is not tightly bonded to the concrete. At the same time, because the water-stopping structure often needs to be connected to the concrete through expansion bolts, this will cause accidental cracking and damage of the concrete, and ultimately fail to achieve the anti-seepage effect.
