Abstract

The invention discloses a jacking type grout pouring operation device, which belongs to the technical field of building construction; it is integrally built in a grouting pipe; it includes a locking support part, a longitudinal positioning part and a horizontal jacking part; wherein the locking support part is used for pouring The operating device is fixedly supported at a certain depth in the grouting pipe; a vertical through hole is opened at the top center of the locking support part, the central installation pipe passes through the through hole, the top of the central installation pipe protrudes from the upper opening of the through hole and its The bottom end is connected to the horizontal jacking part; the end of the horizontal jacking part facing the inner wall of the grouting pipe is provided with a grouting nozzle, and the side of the grouting pipe is provided with a side wall opening for the grouting liquid to pass through; the longitudinal positioning part is installed in the center Between the outer wall of the pipe and the bottom of the locking support part, it is used to fine-tune the depth position of the central installation pipe when it is pulled up and down.

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...
