Underground diaphragm wall reinforcement cage structure with formworks and construction method of underground diaphragm wall reinforcement cage structure

Abstract

The invention belongs to the technical field of municipal engineering underground diaphragm wall construction, and particularly relates to an underground diaphragm wall reinforcement cage structure with formworks and a construction method of the underground diaphragm wall reinforcement cage structure. The underground diaphragm wall reinforcement cage structure comprises an underground diaphragm wall reinforcement cage, and steel plates are arranged at the bottom end and on the two side surfaces of the underground diaphragm wall reinforcement cage. Multiple pieces of channel steel are welded to the two side surfaces of the underground diaphragm wall reinforcement cage, and the underground diaphragm wall reinforcement cage is provided with the steel plates through the channel steel. The channel steel is welded with the steel plates or is in adhesive connection with the steel plates through an adhesive. The steel plate on the outer side surface of the underground diaphragm wall reinforcement cage is a stainless steel plate, and the underground diaphragm wall reinforcement cage is welded with the stainless steel plate through the channel steel; and the steel plate on the inner side surface of the underground diaphragm wall reinforcement cage is a common steel plate, and the underground diaphragm wall reinforcement cage is in adhesive connection with the common steel plate through the channel steel by using the adhesive. According to the invention, the steel plate formworks are between the inner and outer surfaces of a preset underground diaphragm wall and a soil body, the surface quality and the internal compactness of concrete are improved, a continuous waterproof layer is formed on the outer surface of the diaphragm wall, and the leakage and seepage resistance of the underground diaphragm wall is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of underground diaphragm wall construction in municipal engineering, and in particular relates to an underground diaphragm wall reinforced cage structure with formwork and a construction method thereof. Background technique [0002] Existing underground continuous wall adopts a kind of groove digging machine (grooving machine) on the ground, along the center line of the guide wall completed in advance, and under the condition of mud retaining wall, a narrow and long deep groove is excavated in sections, clearing After the trough, hang the reinforcement cage in the trough, and then use the conduit method to pour underwater concrete to form a unit trough section, so that a continuous reinforced concrete wall is built underground as a water interception, seepage prevention, and load bearing. , Water retaining structure. If the external water pressure is high, water seepage will occur during the pouring of the ...
