Abstract
The utility model discloses a kind of anchor pole check valve assembly, comprise valve body, check unit and plastics stifled, described valve body front end is outside thread or internal thread, with being threaded of anchor rod body tail end, be hexagonal structure outside rear end, and Roofbolt drilling rig match, and block stifled with described plastics, rear inside is internal thread, can be connected with grouting equipment joint, and described check unit is assembled on the internal thread of described valve rear end; Check unit described in the utility model can make slurry in anchor hole enrich full, prevents injecting cement paste from flowing backwards, and this model utility both can connect rig tool skyhook, can connect again grouting equipment and make filling adaptor, and structure is simple, easy to operate, practical reliable; The utility model supports the use together with anchor pole, is applicable to the surrounding rock supporting in underground engineering, mine working, tunnelling works.
Description
Technical field
The utility model relates to the anchor pole of a kind of underground engineering, mine working, tunnelling works, particularly relates to a kind of anchor pole check valve assembly.
Background technique
In the underground engineering of geotechnical engineering design, mine working, tunnelling works, cave in for preventing stratum deformation or unstability and jeopardize safety, the main support pattern that formation carries out reinforcing adopts anchor pole.At present, hollow grouting anchor is wherein a kind of main the mode of the bolt support, and because anchor bolt construction operating process is complicated, in work progress, injecting cement paste easily flows backwards, and causes anchoring effect poor, and using effect is not good.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides that a kind of structure is simple, constructing operation is convenient, a kind of anchor pole check valve assembly that can prevent mud from flowing backwards.
The purpose of this utility model is achieved through the following technical solutions:
A kind of anchor pole check valve assembly, comprise valve body 1, check unit 2 and plastics stifled 3, described valve body 1 front end is outside thread or internal thread, it is hexagonal structure outside rear end, rear inside is internal thread, described check unit 2 is assembled on the internal thread of described valve body 1 rear end, and stifled 3 shutoff of described plastics are in described valve body 1 rear end.
The utility model has the following advantages:
Valve body front end described in the utility model is outside thread or internal thread, with being threaded of anchor rod body tail end, is hexagonal structure outside rear end, match with Roofbolt drilling rig, rear inside is female thread structure, is connected with grouting equipment joint, operates easy to use; It is full that described check unit can make the slurry in anchor hole enrich, and after preventing slip casting process or slip casting, slurry flows backwards, and therefore improves anchoring quality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation Fig. 1.
Fig. 2 is the utility model Fig. 1 structure side view.
Fig. 3 is the utility model structural representation Fig. 2.
Fig. 4 is the utility model Fig. 3 structure side view.
Embodiment
Below in conjunction with accompanying drawing, by specific embodiment, technical solutions of the utility model are described further.
As Figure 1-4, Fig. 1, Fig. 2 are the utility model structural representation Fig. 1 and side view; Fig. 3, Fig. 4 are the utility model structural representation Fig. 2 and side view.A kind of anchor pole check valve assembly, comprise valve body 1, check unit 2 and plastics stifled 3, described valve body 1 front end is outside thread or internal thread, it is hexagonal structure outside rear end, rear inside is internal thread, described check unit 2 is assembled on the internal thread of described valve body 1 rear end, and stifled 3 shutoff of described plastics are in described valve body 1 rear end.
Valve body front end described in the utility model is outside thread or internal thread, with being threaded of anchor rod body tail end, is hexagonal structure outside rear end, match with Roofbolt drilling rig, rear inside is female thread structure, is connected with grouting equipment joint, operates easy to use; It is full that described check unit can make the slurry in anchor hole enrich, and after preventing slip casting process or slip casting, slurry flows backwards, and therefore improves anchoring quality.
Although the utility model with preferred embodiment openly as above; but they are not for limiting the utility model, anyly haveing the knack of this those skilled in the art, not departing from the spirit and scope of the utility model; can make various changes or retouch from working as, but same within protection domain of the present utility model.
