Underground diaphragm wall and construction method

Abstract

The invention relates to an underground diaphragm wall and a construction method. The underground diaphragm wall is characterized in that an inner supporting body is arranged between fabricated guidewalls, and the positions of guide wall inner molds can be controlled through the inner supporting body and corner supporting bodies; the transverse positions of a fixed supporting rod, a rotating supporting rod and a top rib bed-jig are dynamically controlled through a moving support; hoisting of an underground diaphragm wall reinforcement cage is carried out through an outer fastening hoisting plate and a hoisting connecting ring on a reinforcement end plate; an upper-layer support plate, a lower-layer support plate and an anti-floating press plate are adopted for limiting the vertical position of the underground diaphragm wall reinforcement cage; the longitudinal position of a casting platform plate is controlled through a wall-side rail and a sliding supporting body, the height of a lifting connector is controlled through a lifting control body, and the transverse position of a filling pipeline is controlled through a transverse movement connector and a transverse movement control body; and a rigid scraping plate and a flexible scraping plate are synchronously adopted for carrying out structural steel end plate wall brushing construction. The bundling and hoisting construction equality of the underground diaphragm wall reinforcement cage can be improved, the stress performance of the construction structure can be improved, and the concrete pouring construction quality can beimproved.

Description

technical field [0001] The invention relates to an underground continuous and construction method capable of improving the binding and hoisting construction quality of the ground connecting wall reinforcement cage, improving the mechanical performance of the construction structure, and improving the construction quality of concrete pouring, belonging to the field of foundation pit engineering, and applicable to underground continuous wall construction projects . Background technique [0002] During the excavation of the foundation pit, the underground diaphragm wall is often used as the retaining structure and water-stop structure. During the construction of the underground diaphragm wall, the construction quality of the guide wall structure, the hoisting construction of the steel cage, and the construction quality of the concrete pouring are often the key points and difficulties of quality control. [0003] In the prior art, there is a structural superimposed underground d...
