Abstract
The utility model relates to the technical field of composite foundations, in particular to a pile foundation with cement slurry injected in a steel pipe with openings in the side wall. The pile foundation comprises guide pipe columns, slurry outlets are formed in the side walls of the guide pipe columns, grouting pipe columns are arranged in the guide pipe columns, the upper end faces of the guide pipe columns and the lower end faces of the guide pipe columns are provided with an upper end cover and a lower end cover respectively, a grouting pump communicated with the grouting pipe columns is connected onto the upper end cover, a lead-in drill bit is connected to the lower surface of the lower end cover, and a plurality of injection holes are formed in the pipe column walls of the grouting pipe columns. The pile foundation with the cement slurry injected in the steel pipe with the openings in side wall improves the strength and the stiffness of steel pipe piles (the guide pipe columns) with openings in the side walls, also improves and reinforces the foundation around a pile body and the foundation of a pile bottom, improves the bearing capacity of the pile bottom and the friction force around the pile, and is reasonable in structural design, firm, stable and capable of well meeting the high requirements for foundations of structures.
Description
Technical field
The utility model relates to the technical field of composite foundation, the pile foundation of grouting methol in especially a kind of side-wall hole steel pipe.
Background technology
Existing natural soil ground is due to reasons such as geology, many times all can not directly meet the requirement of works to bearing capacity of foundation soil, in recent years, along with the fast development of foundation treatment technology and composite foundation research, composite foundation technology has more and more obtained using widely, is especially applied to the basis of roadbed, bridge, pattern foundation pit supporting structure, building construction and industrial premises etc.
Composite foundation refers to that natural ground part soil body in ground processing procedure is enhanced, or replaced, or modified, or reinforcement material is set in natural ground, and stabilization zone is by matrix and reinforcement artificial foundation dimerous.Under load action, the effect of matrix and reinforcement shared load.According to composite foundation load transfer mechanism, composite foundation is divided into vertical reinforcement composite foundation and level to strengthening composite foundation two classes, again vertical reinforcement composite foundation is divided into three kinds of discrete material pile composite foundation, flexible pile composite foundation and rigid pile composite foundations.
Summary of the invention
The technical problems to be solved in the utility model is: the pile foundation that grouting methol in a kind of side-wall hole steel pipe is provided, both the strength and stiffness of side-wall hole steel pipe pile (guiding tubing string) had been improved, improvement has been reinforced pile body around and stake end ground again, stake end bearing capacity and pile peripheral friction force are improved, reasonable in design, solid firm, can meet preferably the high request of works to ground.
The utility model solves the technical scheme that its technical problem adopts: the pile foundation of grouting methol in a kind of side-wall hole steel pipe, comprise guiding tubing string, guiding tubing string sidewall is provided with slurry outlet, in guiding tubing string, be provided with slip casting tubing string, on the upper surface of guiding tubing string and lower surface, be respectively arranged with upper end cover and bottom end cover, on upper end cover, be connected with the grouting pump being connected with described slip casting tubing string, the soffit of bottom end cover is connected with importing drill bit, offers multiple pressure injections hole on the tubing string wall of slip casting tubing string.
Further limit: be opened on the multiple pressure injections hole on the tubing string wall of slip casting tubing string casting head is all installed.
Further limit: import on drill bit and offer multiple pile crown casting heads and pile crown slurry outlet.
The beneficial effects of the utility model: the pile foundation of grouting methol in this side-wall hole steel pipe, both the strength and stiffness of side-wall hole steel pipe pile (guiding tubing string) had been improved, improvement has been reinforced pile body around and stake end ground again, stake end bearing capacity and pile peripheral friction force are improved, reasonable in design, solid firm, can meet preferably the high request of works to ground.
