Abstract
The utility model relates to a supporting structure of a fractured rock mass side slope, and aims to provide the supporting structure, which is simple in structure and convenient to construct so as to enlarge cement mortar scattering ranges, of the fractured rock mass side slope, and improve mutual contacting ability of an anchor pile in the supporting structure of the fractured rock mass side slope and surrounding rock masses, supporting effect of the anchor pile and stability of the side slope. According to the technical scheme, a grouting hole is drilled in the slope surface of a fractured rock mass, and the supporting structure of the fractured rock mass side slope is characterized in that an anchor pile grouting pipe combined with a grouting pipe consolidation function is arranged inside the grouting hole, grouting consolidation construction is conducted on the anchor pile through the anchor pile grouting pipe, and the anchor pile is formed after the grouting hole is filled up with grouting pressure and grouting liquid. The supporting structure of the fractured rock mass side slope is suitable for adopting a supporting structure mode with the anchor pile and grouting consolidation in supporting of the fractured rock mass side slope, and is mainly applied to hydropower engineering, highway engineering, mine engineering and the like.
Description
Technical field
The utility model relates to a kind of supporting and protection structure of fragmented rock body side slope.Be applicable to and in the fragmented rock body slope retaining, adopt anchor pile to add the supporting and protection structure form of fixed grouting, be mainly used in Hydraulic and Hydro-Power Engineering, highway engineering, mine engineering etc.
Background technology
In the slope treatment of rock mass condition difference, conventional anchor pile is after slip casting, and its cement mortar range of scatter is limited, can not make anchor pile around the fragmented rock body globality effectively improve, thereby cause anchor pile effectively not contact with its surrounding rock body, that does not bring into play anchor pile should have effect.
Summary of the invention
The technical problems to be solved in the utility model is: at the problem of above-mentioned existence, a kind of supporting and protection structure of fragmented rock body side slope of simple in structure, easy construction is provided, to enlarge the cement mortar range of scatter, anchor pile and surrounding rock body are in contact with one another ability in the enhancing fragmented rock body slope retaining, improve the supporting effect of anchor pile and the stability of side slope.
The technical scheme that the utility model adopted is: a kind of supporting and protection structure of fragmented rock body side slope, on fragmented rock body is domatic, be drilled with the injected hole of anchor pile, it is characterized in that: lay the anchor pile Grouting Pipe that has consolidation grouting pipe function concurrently in the described injected hole, described anchor pile is by carrying out the consolidation grouting construction through the anchor pile Grouting Pipe, grouting pressure and grouting liquid form after filling with injected hole.
The beneficial effects of the utility model are: the utility model is for improving the engagement capacity of anchor pile and surrounding rock body, reach the due supporting effect of anchor pile, the Grouting Pipe of anchor pile is used as side slope consolidation grouting pipe, this pipe is brought into play the function of domatic consolidation grouting pipe and anchor pile slip casting simultaneously, construct according to consolidation grouting pressure during slip casting, can improve the compactness of anchor pile surrounding rock body like this, strengthen the adhesion stress of anchor pile and surrounding rock body, make anchor pile and the cement mortar around it form the bigger rigid pile body structure of rigidity, greatly bring into play the anchoring ability of anchor pile, reach the supporting effect of side slope side slope.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, present embodiment is a kind of supporting and protection structure of fragmented rock body side slope, is drilled with the injected hole of anchor pile 2 on fragmented rock body domatic 1, lays anchor pile Grouting Pipe 3 in the injected hole, and this Grouting Pipe can be used as side slope consolidation grouting pipe and uses.According to slip castings in the past anchor pile Grouting Pipe 3 of consolidation grouting pressure, carry out the construction of fragmented rock body consolidation grouting in this example, slurries form anchor pile 2 after filling with injected hole.Present embodiment makes anchor pile 2 and its cement mortar on every side form the bigger rigid pile body structure of rigidity, greatly brings into play the anchoring ability of 2 pairs of side slopes of anchor pile, reaches the supporting effect of side slope.
The job practices of present embodiment is as follows: at first, that finishes fragmented rock body domatic 1 is excavated to the design build, is drilled with injected hole; Secondly, in the hole, lay anchor pile Grouting Pipe 3; Carry out the consolidation grouting construction by anchor pile Grouting Pipe 3, the grouting pressure of consolidation grouting is determined according to the geological conditions of domatic fragmented rock body, the grouting pressure size is moderate, and the anchor pile supporting control range that reaches designing requirement gets final product, and concentration of slurry should be determined according to the rock mass condition.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
