Abstract

The invention discloses a grouting foundation structure. The grouting foundation structure comprises a grouting pipe body, wherein an anchoring pipe is arranged in the grouting pipe body; the top part of the anchoring pipe extends out of the outer side surface of the top of the grouting pipe body; the bottom of the anchoring pipe penetrates through a connecting pipe; the connecting pipe is transversely arranged on the grouting pipe body, and the connecting pipe extends out of the two outer side surfaces of the grouting pipe body; a left supporting member and a right supporting member are vertically arranged on the connecting pipe respectively; the bottoms of the left supporting member and the right supporting member penetrate through the bottom of the grouting pipe body; a bottom protecting plate is arranged at the bottom of the grouting pipe body; the bottom protecting plate and the grouting pipe body are connected detachably. According to the grouting foundation structure, the frictional force between the grouting pipe and an anchoring rod hole is effectively increased, so that the effect of preventing the grouting pipe being ejected outside by pressure is realized, strong reinforcing performance is realized, the construction cost is reduced correspondingly, the water sealing effect is very strong, the strength of the foundation is higher, and the mixing mode of the grout is easy to control.

Description

Injected foundation structure
Technical field
The present invention relates to a kind of foundation structure, particularly a kind of injected foundation structure.
Background technology
Two fluid grouting ground is to improve for the purpose of soil, increases the intensity of soil property on the one hand, can reach again the effect of sealing leak stopping on the other hand.For the stratum of various complexity, need to inject various types of injecting paste material according to the actual conditions of engineering, just must adopt multiple slip casting construction method, just can reach the improved effect of designing requirement and anticipation.Although with the main purpose that the intensity improveing soil and sealing performance are basement process, in practice of construction process, all different problems can be run into and get into a difficult position.First, the effect of geology improvement is first, and for making stratum keep nature, only using water and soil to reach improved effect is our research direction from now on.And general injected foundation structure can not reach good slip casting performance, can better arbitrarily not regulate.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, a kind of frictional force that effectively can increase Grouting Pipe and bolthole is provided, to play the effect preventing from Grouting Pipe to be under pressure being ejected, there is very strong reinforcement performance, the injected foundation structure of construction cost also corresponding reduction.
To achieve these goals, the technical solution used in the present invention is such: injected foundation structure of the present invention, comprise Grouting Pipe body, anchoring pipe is provided with in Grouting Pipe body, anchoring pipe top is extended on Grouting Pipe bodies top lateral surface, arrange through a tube connector bottom anchoring pipe, tube connector is horizontally installed on Grouting Pipe body, and tube connector extends on Grouting Pipe body two lateral surface, tube connector is vertically provided with left support component and right support component respectively, left support component and right support member bottom section are all arranged through Grouting Pipe body bottom portion, Grouting Pipe body bottom portion is provided with bottom guard plate, removably is adopted to be connected between bottom guard plate with Grouting Pipe body.
Further, as a kind of concrete form of structure, Grouting Pipe body two sides of the present invention are provided with some penetrating and starch hole.
Further, as a kind of concrete form of structure, anchoring pipe diameter of the present invention is between 50 to one hundred millimeters.
Further, as a kind of concrete form of structure, tube connector two ends of the present invention are provided with sealing-plug.
Further, as a kind of concrete form of structure, removably connect between tube connector of the present invention and anchoring pipe.
Compared with prior art, the invention has the advantages that: this injected foundation structure effectively can increase the frictional force of Grouting Pipe and bolthole, to play the effect preventing from Grouting Pipe to be under pressure being ejected, there is very strong reinforcement performance, construction cost is corresponding reduction also, sealing performance is very strong, and foundation strength is also larger, and slurries hybrid mode easily controls.
