Embodiment Construction

[0013] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0014] Such as figure 1 The preferred embodiment of the grouting foundation structure of the present invention shown includes a grouting pipe body 1, and an anchor pipe 2 is arranged in the grouting pipe body 1, and the top of the anchor pipe 2 extends out of the top outer surface of the grouting pipe body 1, and is anchored The bottom of the pipe 2 passes through a connecting pipe 3. The connecting pipe 3 is arranged horizontally on the grouting pipe body 1, and the connecting pipe 3 extends out of the two outer surfaces of the grouting pipe body 1. The connecting pipe 3 is vertically provided with left and right sides. The support member 5 and the right sup...

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

technical field [0001] The invention relates to a foundation structure, in particular to a grouting foundation structure. Background technique [0002] The purpose of the double-fluid grouting foundation is to improve the soil. On the one hand, it can increase the strength of the soil, and on the other hand, it can achieve the effect of water and leakage plugging. For various complex formations, various types of grouting materials need to be injected according to the actual situation of the project, so a variety of grouting methods must be used to achieve the design requirements and expected improvement effects. Although the main purpose of foundation treatment is to improve the strength of the soil and waterproof performance, in the actual construction process, it will encounter different problems and get into trouble. First of all, the effect of geological improvement is the first. In order to maintain the natural state of the stratum, only using water and soil to achieve...
