Construction method of water-stopping combined continuous wall prefabricated by centrifugal process

Abstract

The present invention relates to a construction method of a water-stop combined continuous wall precasted by centrifugation. In order to form the water-stop combined continuous wall of the present invention, the concrete bodies (1) of a plurality of reinforced concrete members are proximately arranged with the lower sections planted into the ground, and each concrete body is structured as: water-stop grooves (2) are symmetrically arranged longitudinally from the head to the tail; each side can be provided with one or more water-stop grooves; water-stop material (7) is filled into water-stop cylindrical cavities (3) formed by the water-stop grooves of two adjacent concrete bodies; the top of each concrete body is provided with a connecting plate (4), which is provided with a preformed hole (6) in which a bar reinforcement (8) can be plugged; a cap beam (5) and the concrete bodies are casted together by the connecting bar reinforcements, the connecting plates and concrete, and the cap beam connects the arranged concrete body members as a whole to form an integral continuous wall. The present invention has the advantages of low construction cost, short construction period, good water-proof property, resource saving, reliable quality and high safety.

Description

Technical field: [0001] The invention relates to a continuous wall combined with foundation pit support and water stop soil retaining for industrial and civil buildings, bridges, ports, etc., and belongs to the field of foundation pit support for foundation treatment of construction engineering. Background technique: [0002] Foundation pit engineering is an ancient geotechnical engineering subject with the characteristics of the times. Under the situation of my country's reform and opening up and the continuous rapid growth of the national economy, the national engineering construction has also advanced by leaps and bounds, and a large number of high-rise and super high-rise buildings have sprung up rapidly. In order to ensure the stability of the building, the building foundation must meet the requirements of deep embedding underground. At the same time, in order to maximize the use of the non-renewable land resources on which human beings depend for survival, fully develo...

Problems solved by technology

Due to the influence of construction technology and geological structure, the above-mentioned support forms often easily lead to insufficient hole-forming grouting, force of soil nails or anchors not meeting the design requirements, insufficient thickness of sprayed concrete, and insufficient strength to meet the design requirements. The difference from the design is too large, the difference between the design and the actual situation is large, the project cost is high, the construction period is long, the quality and safety controllability is poor, the safety factor is low, resources are wasted, and the construction has a large impact on the surrounding environment.

Especially in the support of soft soil foundation and deep foundation pit, the above-mentioned defects are particularly prominent, and in some areas, it is impossible to construct at all.
