Steel plate and concrete combined underground continuous wall and construction method thereof

Abstract

The invention provides a steel plate and concrete combined underground continuous wall which is formed by the connection of a plurality sections of wall bodies, and each wall body is composed of two outer steel plates (1) and inner concrete (2), the two outer steel plates (1) are connected with cylindrical cross-pulling rebars (3) and rectangular vertical baffles (4), as the vertical baffles (4) are arranged between the two steel plates, the concrete can be poured into branched storehouses and the joint pipes are saved; the end part of each steel plate (1) is bent into an L-shape to form a steel plate joint (6), so as to guarantee the wall body to be provided with better anti-permeability after butt joint; the wall is in mutual vertical connection with a beam plate (7) of the architectural structure, the rebar of the beam plate (7) can be welded onto the steel plate of the underground continuous wall, and rebars or the stiffeners (8) of the steel plate and the triangular bearing (9) are arranged on the relevant position of the wall body. The invention further provides a construction method of the steel plate concrete composite underground continuous wall, which comprises six steps. The underground continuous wall provided by the invention is good in anti-permeability, small in wall body section and is provided with supporting and bearing functions.

Description

Technical field: [0001] The invention relates to a two-in-one double steel plate concrete composite underground continuous wall and a construction method thereof. It belongs to the technical field of underground diaphragm wall construction. Background technique [0002] At present, the underground diaphragm wall is being used more and more in foundation pit engineering, because it can not only serve as a retaining structure and water-stop curtain to complete the basic functions of foundation pit support, but also can be used as the outer wall of a building to bear load. [0003] The traditional reinforced concrete underground diaphragm wall may lose its waterproof function due to poor impermeability of the joints or uneven settlement and cracking of the wall during use. When it is used as the exterior wall of a building, it needs to design a larger cross-sectional size to ensure the bearing capacity. [0004] Aiming at the shortcomings of the traditional reinforced concre...
