Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
Embodiment 1
As shown in Figure 1-3, a kind of connector for recoverable anchor pole of the present embodiment, including a connecting sleeve 1,
The connecting sleeve 1 is equipped with the second thread segment 12, and at least provided with the first screw thread for being radially arranged in 12 outside of the second thread segment
Section 11, first thread segment 11 are used to cooperate the isolated tube 3 of screw rod, and second thread segment 12 is described for cooperating anchor pole
The anchor pole that first thread segment 11 is connect with the isolated tube 3 cooperation insulation blocking with the second thread segment 12.
Connector of the invention is arranged in the double thread section of connecting sleeve 1, and the second thread segment 12 is threadably secured connection
Chemical formula anchor pole 4, the first thread segment 11 are threadably secured connection isolated tube 3, promote anchor pole connection and connect and tear open with isolated tube
It unloads.
In rockbolt installation, chemical formula anchor pole 4 is directly rotated, and be threadably secured and be connected to the second thread segment 12, so
Rotation isolated tube 3 is threaded in the first thread segment 11 afterwards, and after isolated tube 3 is installed, chemical agent is injected chemical anchoring section
6a carries out chemical anchoring after completing injection.This structure can be when injecting chemical agent or after the completion of injection, direct screw thread rotation
Back-out slip casting anchor stock 4, easy removal goes out slip casting anchor stock, swift to operate, easy, anchor pole can recycled for multiple times, save significantly
The about dosage of anchor pole steel.
The connecting sleeve 1 is additionally provided with third thread segment 13, and the third thread segment 13 is arranged in first thread segment
11 opposite end, namely the first thread segment 11, the second thread segment are set gradually on the other end of connecting sleeve 1, connecting sleeve 1
12 and third thread segment 13, wherein the both ends of the connecting sleeve 1, institute is arranged in the first thread segment 11 and third thread segment 13
It states the connection of third thread segment 13 and is equipped with the externally threaded chemical dowel 6 that matches.
The present embodiment mainly for Soft Soil, if there are three threaded connection section, the chemical formula anchor of 1 one end of connecting sleeve connection
The installation and removal of bar 4 are convenient, and isolated tube 3 facilitates installation not to be corroded with insulation blocking chemical formula anchor pole 4, and chemical dowel 6 includes
Chemical anchor bolts pencil blender 61 and anchor rib 62 positioned at front end, chemical agent solidification can reduce bump in Bracing Process
Bring influences, and substantially increases the stability of country rock, chemical dowel 6, which stays in, forms permanent support in Soft Soil.
The anchor pole of the connector connection selects chemical formula anchor pole, and 1 outer wall of connecting sleeve is equipped with anchor bolt medicament non-return
Baffle 7 is equipped with the chemical formula anchor pole elasticity backflow preventing mouth plug 5 in outer wall, can effectively prevent chemical agent reflux, reduce because
Chemical agent reflux influences anchoring effect.
In this structure, second thread segment 12 selects the screw thread of cooperation steel screw thread, and chemical formula anchor pole selects finish rolling screw thread
Steel.
In order to improve the isolation effect of isolated tube 3, first thread segment 11 is close to the end of second thread segment 12
111 are equipped with seal washer.
