Wall type foundation and construction method thereof

Abstract

The invention provides a wall type foundation and a construction method thereof. An integral foundation unit is arranged; an enclosing wall of the whole foundation unit comprises a plurality of side walls; a plurality of side walls form an integral polygonal cylindrical foundation structure; and a sealing top is positioned on an enclosing wall and is connected with the side wall. By arranging the integral enclosing wall, joints formed by sequentially connecting the side walls are avoided, so various problems caused by the joints of the side walls are avoided; a hollow closed-loop structure formed by connecting a plurality of side walls is adopted, bearing capacity is provided through interaction of the hollow closed-loop structure and soil bodies on the two sides and the lower ends of the surrounding side walls after the hollow closed-loop structure is implanted into the soil bodies, friction force inside and outside the walls is fully utilized, the bearing capacity of the foundation is increased, stability of the structure is improved, and the structure is safe and reliable; and meanwhile, transverse pulling force on the side walls is achieved by sealing the tops of the positioning covers on the enclosing walls, the bearing capacity of the whole foundation unit is greatly improved, and better economical efficiency and practicability are achieved.

Description

technical field [0001] The invention relates to the technical field of building foundations, in particular to a wall foundation and a construction method thereof. Background technique [0002] The existing pile group foundation and caisson foundation are about 30-70 meters long, and the diameter of the cross-section is about 6-9 meters. The whole foundation is mostly a prefabricated solid pile foundation structure, and most of them are submerged by their own weight during construction. The long construction period, high geological requirements, and difficulties in transportation of prefabricated components and difficulties in hoisting equipment will lead to low construction efficiency and long construction period. [0003] At the same time, in the existing underground foundation, each side wall is poured and connected in sequence. It is inevitable that there will be joints between the side walls, which will easily lead to uneven pressure on the side walls, and the joints wil...

AI Technical Summary

Problems solved by technology

[0002] The existing pile group foundation and caisson foundation are about 30-70 meters long, and the diameter of the cross-section is about 6-9 meters. The whole foundation is mostly a prefabricated solid pile foundation structure, and most of them adopt the method of sinking by their own weight during construction. The construction period is long, the geological requirements are high, and the transportation of prefabricated components is difficult, and the lifting equipment is difficult, which will lead to low construction efficiency and long construction period.

[0003] At the same time, in the existing underground foundation, each side wall is poured and connected in sequence. It is inevitable that there will be joints between the side walls, which will easily lead to uneven pressure on the side walls, and the joints will easily spread, and at the same time, water seepage or Water leakage seriously affects the quality of the entire foundation
