On structural plane, basic foundation bolt needs directly pre-buried in flow-passing surface.
Due to the particularity of hydraulic and hydroelectric engineering, in foundation bolt, joint bar of hydraulic structure flow-passing surface arrangement etc., later stage
Need first to dig concrete surface after dismounting and cheat, then cut off, ensure foundation bolt, joint bar appear less than concrete flow-passing surface 5 ~
10cm (be specifically subject to design requirement) carries out concrete table using materials such as epoxy resin mortars again after bolt, joint bar head are cut off
The repairing of planar defect, operational procedure is complicated, difficulty is big, handles heavy workload, and the quality of concrete overcurrent surface treatment is difficult to protect
Card.
The content of the invention
In order to overcome the problems, such as present in background technology, it is pre-buried that the utility model provides a kind of hydraulic structure flow-passing surface
Foundation bolt, construction is simple, cost is small, and the later stage removes and the processing of concrete surface defect repair is easy for construction, and quality can ensure,
Influence to hydraulic structure flow-passing surface is small.
To achieve the above object, the utility model is achieved by the following technical solution：
The hydraulic structure flow-passing surface pre-embedded anchoring bolts include anchoring section 1, sleeve 2, pvc pipe 3, linkage section 4, institute
Be provided with outer silk tooth on the upper end end for the anchoring section 1 stated, the both ends end of linkage section 4 is both provided with outer silk tooth, anchoring section 1 with
The diameter of linkage section 4 is consistent, and internal thread tooth is provided on the inner wall of sleeve 2, and anchoring section 1 is connected with linkage section 4 by 2 teeth of sleeve
An entirety is formed, the linkage section 4 of 2 top of sleeve is socketed with pvc pipe 3 without silk tooth section.
Further, the forward end of the anchoring section 1 is in hook formation.
Further, the interior caliber of the pvc pipe 3 is more than the diameter of anchoring section 1 and linkage section 4, and with the outer diameter of sleeve 2
It is identical.
The beneficial effects of the utility model：
This utility model is simple in structure, reliable in quality, and cost is small, and the later stage removes and the processing of concrete surface defect repair is applied
Work is convenient, and the influence to hydraulic structure flow-passing surface is small, there is preferable economic and social benefit.

Specific embodiment
In order to make the purpose of this utility model, technical solution and advantageous effect clearer, below in conjunction with attached drawing, to this
The preferred embodiment of utility model is described in detail, to facilitate the technical staff to understand.
As shown in Figs. 1-3, the hydraulic structure flow-passing surface pre-embedded anchoring bolts include anchoring section 1, sleeve 2, pvc pipe
3rd, linkage section 4 are provided with outer silk tooth on the upper end end of the anchoring section 1, and the both ends end of linkage section 4 is both provided with outer silk
Tooth, anchoring section 1 is consistent with the diameter of linkage section 4, and internal thread tooth is provided on the inner wall of sleeve 2, and anchoring section 1 passes through with linkage section 4
2 teeth of sleeve connect to form an entirety, and the linkage section 4 of 2 top of sleeve is socketed with pvc pipe 3 without silk tooth section.
The forward end of the anchoring section 1 be in hook formation, can so ensure anchoring section 1 can with concrete 5 into
Row stable anchorage.
The interior caliber of the pvc pipe 3 is more than the diameter of anchoring section 1 and linkage section 4, and identical with the outer diameter of sleeve 2.
The course of work of the utility model：
As illustrated in figures 4-5, sleeve 2 is socketed in the upper end of anchoring section 1, during architecture construction, by anchoring section 1 and sleeve 2
The entirety that connection is formed is embedded in advance in concrete 5, and ensures the 5~10cm suitable for reading away from the upper surface of concrete 5 of sleeve 2, is covered
Cylinder 2 is suitable for reading to the pre-buried pvc pipe 3 of 5 upper surface of concrete section, and 3 caliber of pvc pipe is more than the diameter of anchoring section 1 and linkage section 4, can be with
The outer diameter of female connector cylinder 2 is identical, and ensures plummet and coaxial with female connector cylinder 2, meanwhile, in work progress, carry out that sleeve 2 is suitable for reading, PVC
The protection of 3 nozzle of pipe, before the installation of construction in later period equipment, clear and coherent pvc pipe 3 and sleeve 2, by linkage section 4 through straight from pvc pipe 3
