Abstract
The utility model relates to an autocontrol hollow slip casting anchor rod which comprises a slip casting pipe (3). A group of slip casting holes is arranged on the slip casting pipe (3), an anchor head (1) is arranged at one end of the slip casting pipe (3), a hollow screw (8) is arranged at the other end of the slip casting pipe (3), a tray (6) is sleeved on the hollow screw (8), and a nut (7) which is in threaded connection is further arranged on the hollow screw (8) to limit the tray (6) on the hollow screw (8). The autocontrol hollow slip casting anchor rod is characterized in that a one-way valve (4) is arranged in the slip casting pipe (3) corresponding to the hollow screw (8). The autocontrol hollow slip casting anchor rod has the advantages in that the one-way valve is built in the slip casting anchor rod, serious fluid cannot flow out from other slip casting anchor rods, an autocontrol valve closes a liquid inlet of the slip casting anchor rod after slip casting is stopped, high pressure serious fluid can be prevented from flowing out, and safety and hole changing efficiency of the slip casting anchor rod are improved.
Description
Technical field
The utility model relates to the anchor pole that colliery tunnel support uses, especially a kind of autocontrol hollow grouting anchor.
Background technology
Existing grouted anchor bar is interconnected when slip casting easily, and the high pressure slurries are scurried out from grouted anchor bar, causes slurries to spread to the depths, has influenced slip casting effect; Need add control valve on the grouted anchor bar during down-hole slip casting, spray orifice when preventing to change the hole also need be taked the plug-hole measure when other adjacent grouted anchor bars are scurried the hole, increases difficulty of construction, reduces efficiency.In addition, existing grouted anchor bar is inserted in the rock mass, and grouted anchor bar comes off when preventing that grouting pressure is big, needs fix with the anchoring agent, causes waste of material.In addition, existing grouted anchor bar causes this place's tube wall attenuation that Anchoring Strength of Rock Bolts is significantly reduced because of tail end car silk, can not bring into play the anchorage effect of grouted anchor bar.
The utility model content
The purpose of the utility model is exactly in order to overcome the defective of prior art, and a kind of autocontrol hollow grouting anchor is provided.
The utility model solves the technical scheme that its technical problem adopted:
The autocontrol hollow grouting anchor; Comprise Grouting Pipe, Grouting Pipe is provided with one group of injected hole, and Grouting Pipe one end is provided with anchor head; The Grouting Pipe other end is provided with cored screw; Pallet of suit on cored screw is limited in pallet on the cored screw also being provided with the nut that is threaded on the cored screw, it is characterized in that: in the corresponding Grouting Pipe pipe of cored screw, be provided with one way valve.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
Described one way valve comprises valve body; Be provided with stepped endoporus in the valve body; Big corresponding valve body is provided with side down hole in aperture, ladder place, and in the bigger endoporus in aperture, also is provided with and is provided with piston, spring successively, is provided with plug in the end of endoporus piston and spring are encapsulated in the endoporus.
Outside Grouting Pipe, be set with stop grouting plug.
The beneficial effect of the utility model is because the built-in one way valve of grouted anchor bar; Slurries can not scurried out from other grouted anchor bar; And internally piloted valve is closed this grouted anchor bar inlet opening automatically after stopping slip casting, prevents that the high pressure slurries from scurrying out, and has improved the safety of grouted anchor bar and has changed hole efficient.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings:
Fig. 1 is the front view of the utility model;
Fig. 2 is the lateral view of the utility model.
The specific embodiment
As shown in Figure 1, a kind of autocontrol hollow grouting anchor of the utility model comprises Grouting Pipe 3; Grouting Pipe 3 is provided with one group of injected hole, and Grouting Pipe 3 one ends are provided with anchor head 1, and anchor head 12 is fixed on the Grouting Pipe 3 through pinning; Grouting Pipe 3 other ends are provided with cored screw 8, and pallet 6 of suit on cored screw 8 is limited in pallet 6 on the cored screw 8 also being provided with the nut 7 that is threaded on the cored screw 8;, cored screw 8 corresponding Grouting Pipe 3 are provided with one way valve 4 in managing; As shown in Figure 2, described one way valve 4 comprises valve body 42, is provided with stepped endoporus 41 in the valve body 42; Big corresponding valve body 42 is provided with side down hole 44 in aperture, ladder place; And in the bigger endoporus in aperture, also be provided with and be provided with piston 43, spring 45 successively, be provided with plug 46 in the end of endoporus piston 43 and spring 45 are encapsulated in the endoporus, outside Grouting Pipe 3, also be set with stop grouting plug 5.
Grouting Pipe 3 adopts hard materials, and the good boring of construction is earlier directly packed grouted anchor bar in the boring, and self-anchoring type plastics anchor head 1 anchor tightens stop grouting plug 5 at the bottom of the hole; When band mud jacking liquid injects, promote one way valve 4 inner carriers 43, open liquid injection hole, Grouting Pipe 3 is in open mode, and slurries flow in the wall-rock crack that Grouting Pipe 3 inserted through injected hole equably, play glued breaking surrounding rock, improve the effect of country rock internal stress; Because the built-in one way valve 4 of grouted anchor bar, slurries can not scurried out from other grouted anchor bar, and one way valve 4 is closed this grouted anchor bar inlet opening automatically after stopping slip casting, prevent that the high pressure slurries from scurrying out, and have improved the safety of grouted anchor bar and have changed hole efficient.Slip casting can be carried out shotcrete with steel bar nets after accomplishing, and realizes bolt-spary supports, gives full play to the support action of grouted anchor bar.
