Description
Technical field
The utility model relates to the anchor pole in a kind of underground construction, mine working, construction of tunnel, particularly relates to a kind of hollow grouting anchor.
Background technology
In the geotechnical engineerings such as underground construction, mine working, tunnel, water conservancy culvert and side slope protection, for preventing stratum deformation, subside or unstability and need formation to reinforce, the main support technology of the one adopted is bolt support, mostly use metal-resin anchor pole at present, it is mainly divided into two kinds, one is that left-handed nothing indulges rib resin anchor, and another kind is the strong full thread resin anchors such as dextrorotation, all there is different problems during these two kinds of resin anchors use at the scene.The first left-handed nothing indulges rib resin anchor, and the screw thread on anchor rod body surface is less, and resin agitating is insufficient, thus has a strong impact on the anchored force of anchor pole; Greatly, it is insufficient to add resin agitating, causes anchored force also unreliable for the strong full thread resin anchor body of rod such as the second dextrorotation and nut screw connection gap.These two kinds of resin anchors, in use can not mid-anchor rod body owing to not putting middle agitator, and the easy deflection in end of the body of rod, stirs insufficient simultaneously, cause anchoring effect poor, easily causes roof safety accident.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of and installs fast, anchored force is large, supporting effect good, can meet simultaneously and stir and a kind of hollow grouting anchor of existing facility installation clamp nut needs.
The purpose of this utility model is achieved through the following technical solutions:
A kind of hollow grouting anchor, comprise the body of rod 1, spherical nut 2, pallet 3, stop grouting plug 4, non retern valve 5, baffle ring 6, put middle device 7, the described body of rod 1 is the high-intensity hollow body of rod, described spherical nut 2 is fastened on the described body of rod 1 threads, described pallet 3 and described stop grouting plug 4 are enclosed within described spherical nut 2 front portion successively and are enclosed within the described body of rod 1, described non retern valve 5 is arranged on the hollow internal thread position of the described body of rod 1 afterbody by screw thread, described baffle ring 6 is fixed on the front portion of the described body of rod 1, described in put middle device 7 is arranged on the described body of rod 1 front end by internal thread.
The body of rod 1 first half described in the utility model is left-handed coarse thread steep-pitch thread, and latter half of is dextrorotation fine thread, and device 7 and described baffle ring 6 in putting described in being equipped with in the front portion of the described body of rod 1, afterbody is equipped with described non retern valve 5.
The utility model has the following advantages:
Body of rod first half described in the utility model is left-handed coarse thread steep-pitch thread, and latter half of is dextrorotation fine thread, and anchored force is large, and can meet resin fully stirs, and can meet existing facility simultaneously and install clamp nut needs, realize Fast Installation; Describedly put middle device and be contained in lever front end, can lead, the body of rod can be made again to put in the middle of anchor hole, as during with resin end anchor, putting middle device can abundant agitating resin, and anchoring effect is good; Described baffle ring rotates with the body of rod and slurry forward end can be made to flow, and enriches slurries in anchor hole, thus improves anchored force and reliability; The non retern valve that body of rod afterbody is installed, can prevent slip casting from flowing backwards; The utility model can carry out slip casting anchoring according to construction site condition, also after resin end anchor, can carry out slip casting anchoring again, and anchored force increases, supporting effect and good reliability.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, technical solutions of the utility model are described further.
As shown in Figure 1, Fig. 1 is the utility model structural representation.A kind of hollow grouting anchor, comprise the body of rod 1, spherical nut 2, pallet 3, stop grouting plug 4, non retern valve 5, baffle ring 6, put middle device 7, the described body of rod 1 is the high-intensity hollow body of rod, described spherical nut 2 is fastened on the described body of rod 1 threads, described pallet 3 and described stop grouting plug 4 are enclosed within described spherical nut 2 front portion successively and are enclosed within the described body of rod 1, described non retern valve 5 is arranged on the hollow internal thread position of the described body of rod 1 afterbody by screw thread, described baffle ring 6 is fixed on the front portion of the described body of rod 1, described in put middle device 7 is arranged on the described body of rod 1 front end by internal thread.
Body of rod first half described in the utility model is left-handed coarse thread steep-pitch thread, and latter half of is dextrorotation fine thread, and anchored force is large, and can meet resin fully stirs, and can meet existing facility simultaneously and install clamp nut needs, realize Fast Installation; Describedly put middle device and be contained in lever front end, can lead, the body of rod can be made again to put in the middle of anchor hole, as during with resin end anchor, putting middle device can abundant agitating resin, and anchoring effect is good; Described baffle ring rotates with the body of rod and slurry forward end can be made to flow, and enriches slurries in anchor hole, thus improves anchored force and reliability; The non retern valve that body of rod afterbody is installed, can prevent slip casting from flowing backwards.
The utility model can carry out slip casting anchoring according to construction site condition, also after resin end anchor, can carry out slip casting anchoring again, and anchored force increases, supporting effect and good reliability.
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.
