A kind of multi-functional composite mold tube for underground diaphragm wall construction

Abstract

The invention discloses a multifunctional composite mould pipe for construction of an underground diaphragm wall, which is formed by connecting a connecting pipe at the upper end, a forming pipe at the lower end, and a plurality of mould sub-pipes in the middle. Each mould sub-pipe comprises a round-cross-sectioned inner pipe, a first face plate and a second face plate coaxial with the inner pipe are fixedly connected to one side of the inner pipe, a third face plate and a fourth face plate coaxial with the inner pipe are fixedly connected to the other end of the inner pipe, the first face plate is parallel to the second face plate, the third face plate is parallel to the fourth face plate, the first plate and the third plate are on a same plane, the second face plate and the fourth face plate are on a same plane, both one side, far away from of the inner pipe, of the first face plate and one side, far away from the inner pipe, of the second face plate are fixedly and perpendicularly connected with a fifth face plate, both one side, far away from the inner pipe, of the third face plate and one side, far away from the inner pipe, of the fourth face plate are fixedly and perpendicularly connected with a sixth face plate, and the fifth face plate is parallel to the sixth face plate. The multifunctional composite mould pipe has the functions of mould sinking, soil taking and wall formation, and construction quality and efficiency are improved effectively.

Description

technical field [0001] The invention relates to a mold tube for continuous wall construction, in particular to a multifunctional composite mold tube for underground continuous wall construction with the functions of mold sinking, soil extraction and wall formation. Background technique [0002] At present, the construction of underground diaphragm walls usually adopts the methods of drilling and splitting, drilling and grabbing, and vibrating formwork sinking. Because of the high construction cost, many auxiliary operations and the limitation of the depth of the wall, the construction is often difficult to meet the engineering needs and achieve Expected economic indicators. However, the construction technology of continuous soil vibrating and sinking has achieved good results in the construction of thin and deep underground diaphragm walls in sandy soil, cohesive soil, silt fine sand layer and fine sand pebbles. The low cost has laid a solid foundation for the development o...
