Abstract

The invention discloses an I-beam joint structure preventing flowing around a body and water seeping of an underground diaphragm wall and a construction method thereof. The joint structure is composedof an I-beam formed by welding two pieces of wing plate section steel to one piece of web section steel, grout stopping iron sheets, rubber water stopping belts, vertical sealing ribs at the cornersof the ends of a subsequent slot section, blade feet on the bottom of the I-beam joint and the like; the inner sides of the wing plate section steel of the I-beam joint are welded to horizontally distributed ribs of an early slot section, and the grout stopping iron sheets are welded to the outer sides of the wing plate section steel; the rubber water stopping belts stick to the inner sides of thewing plates of the I-beam of the subsequent slot section by means of binder; the vertical sealing ribs are welded at the corners of the ends of a subsequent slot section steel reinforcement cage. According to the joint structure, the integrity is good, construction is easy, the problem that concrete flows around a body is effectively prevented, the anti-seepage effect in a joint is good, and thestructure is applicable to joint connection of an ultra deep underground diaphragm wall.

Description

technical field [0001] The invention belongs to the field of underground diaphragm wall construction in underground engineering, and specifically relates to an underground diaphragm wall anti-circumvention and anti-seepage water I-shaped steel joint structure and a construction method. Background technique [0002] The underground diaphragm wall has the functions of retaining soil and preventing seepage. At the same time, it is widely used in deep foundation pit engineering because of its advantages such as high overall rigidity, small construction vibration, and strong stratum adaptability. The underground diaphragm wall is composed of unit groove sections connected to each other through joints. The quality of the joints is directly related to the integrity of the wall structure and the reliability of anti-seepage, and even more related to the safety of the entire project. [0003] I-beam joints are currently widely used in the joint construction of underground diaphragm wa...
