Construction technology of underground continuous wall

Abstract

The invention discloses a construction technology of an underground continuous wall. The construction technology is characterized by comprising the following steps of S1, measuring and lofting: measuring and lofting an axis control pile of an underground wall according to the lofting requirements; S2, construction of a guide wall: adopting an inverted double L-shaped cast-in-situ reinforced concrete structure for the guide wall; S3, trenching construction of the continuous wall: adopting a hydraulic grab trenching machine for constructing, and performing trench-alternative construction on eachunderground continuous wall along a same straight line section; S4, manufacturing of a reinforcement cage: according to the quantity of trenching equipment and the actual conditions of construction site, centrally processing the accessories of the reinforcement cage in a processing factory, carrying to the site and assembling, and building an assembly platform of the reinforcement cage at site; S5, arranging of concrete guide pipes: adopting quick-joint steel guide pipes in the concrete casting process, enabling a lower opening of each guide pipe to be lower than the bottom of a hole, liftinga casting frame, and connecting the guide pipes; S6, casting the concrete of the wall body. The construction technology has the beneficial effects that by adopting the construction technology method,the production efficiency is conveniently improved, the arrangement of personnel and allocation of materials are convenient, and the construction quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building construction technology, and in particular relates to a construction technology of an underground continuous wall. Background technique [0002] The underground diaphragm wall is a kind of trenching machine used on the ground for basic engineering. Along the peripheral axis of the deep excavation project, a long and narrow deep trench is excavated under the condition of mud retaining wall. After the trench is cleaned, it is hung in the trench Reinforcement cages, and then use the conduit method to pour underwater concrete to form a unit trough section. In this way, a continuous reinforced concrete wall is built underground as a water interception, anti-seepage, load-bearing, and water-retaining structure. [0003] For the arrangement of the construction technology of the diaphragm wall, it will directly affect the efficiency of the construction, and it will also affect the quality of the construc...
