Jacking type slurry pouring operation device

Abstract

The invention discloses a jacking type slurry pouring operation device, and belongs to the technical field of building construction. The jacking type slurry pouring operation device is integrally arranged in a grouting pipe, the jacking type slurry pouring operation device comprises a locking supporting part, a longitudinal positioning part and a transverse jacking part, the locking supporting part is used for fixedly supporting the pouring operation device at a certain depth in a grouting pipe, a vertical through hole is formed in the center of the top of the locking supporting component, a center mounting pipe penetrates through the through hole, the top end of the center mounting pipe extends out of an upper hole opening of the through hole, the bottom end of the center mounting pipe is connected with the transverse jacking component, one end, facing the inner wall of the grouting pipe, of the transverse jacking component is provided with a grouting nozzle, the side face of the grouting pipe is provided with a side wall open hole allowing grouting liquid to pass through, and the longitudinal positioning part is arranged between the outer wall of the center mounting pipe and the bottom of the locking supporting part and used for finely adjusting the depth position of the center mounting pipe when the center mounting pipe is pulled to move up and down. The jacking type slurry pouring operation device has the advantage that grouting construction operation can be independently carried out at a certain depth.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a jacking type grout pouring operation device. Background technique [0002] Pile foundation is a widely used form of deep foundation, which has the advantages of high bearing capacity and small settlement. Among the many types of pile foundations, bored piles are one of the mainstream pile types. At the project site, pile holes are first formed in the foundation soil by means of mechanical drilling, steel pipe extrusion or manual excavation. In order to ensure the stability of the hole wall during the hole forming construction, the mud for the wall needs to be poured into the hole. After the hole is completed A steel cage is placed inside it, concrete is poured, and a reinforced concrete pile foundation is finally formed. In order to obtain a higher bearing capacity, the hole diameter of the pile foundation needs to be enlarged, which will cause a series of probl...

AI Technical Summary

Problems solved by technology

It is difficult to achieve separate construction at a certain depth on the pile side, and it is difficult to guarantee the uniformity of grouting on the pile side after construction is completed
