Another technical problem to be solved in the utility model is to provide a kind of Grouting Pipe, makes operation more simple and convenient.
For solving the problems of the technologies described above, Grouting Pipe embodiment of the present utility model adopts following technical scheme:
, on this Grouting Pipe tube wall interval have an injected hole, described Grouting Pipe is at least more than or equal to boring internal diameter at the external diameter at stone head hell place.
Preferably, the external diameter of described Grouting Pipe is all more than or equal to boring internal diameter; Or the external diameter of described Grouting Pipe at hell place is more than or equal to boring internal diameter, the remainder external diameter that inserts boring is less than boring internal diameter.
Further, on the tube wall of described Grouting Pipe, have along Grouting Pipe and extend axially to the slotted opening of Grouting Pipe one end.
Preferably, the slotted opening in described Grouting Pipe has 2-3.
Preferably, described Grouting Pipe is most advanced and sophisticated for inserting one end of boring.
Grouting Pipe of the present utility model, described Grouting Pipe is at least more than or equal to boring internal diameter at the external diameter at stone head hell place, like this, between the Grouting Pipe at hell place and boring, there is no gap, Grouting Pipe just can realize self shutoff herein, effectively prevented that slurries from leaking outside, made thus the grouting device in deep rock tunnel simple and convenient.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation that in the grouting device in the utility model embodiment deep rock tunnel, the whole external diameters of Grouting Pipe are more than or equal to stone head boring internal diameter.
Fig. 2 is the schematic diagram that in the grouting device in the utility model embodiment deep rock tunnel, the external diameter of Grouting Pipe at stone head hell place is more than or equal to boring internal diameter.
The specific embodiment
Below in conjunction with accompanying drawing, a kind of grouting device for deep rock tunnel of the utility model embodiment and Grouting Pipe are described in detail.
Should be clear and definite, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 1 or 2, the specific embodiment of a kind of grouting device for deep rock tunnel of the utility model, comprise grouting pump (not shown) and Grouting Pipe 1, one end 2 of Grouting Pipe 1 is connected with slip casting delivery side of pump, the other end 3 is for inserting the boring in deep rock tunnel, and at least at the external diameter of the Grouting Pipe 1 at hell place, is more than or equal to boring internal diameter; What Grouting Pipe 1 was inserted interval on the tube wall of boring has an injected hole 4.
