The equal processed filament tooth in upper end and linkage section both ends termination of section, and anchoring section passes through straight thread reinforced bar sleeve connection with linkage section；
2）According to the pre-buried position of equipment anchor bolt during the building concrete construction at construction equipment arrangement position, will process
Foundation bolt anchoring section and sleeve connection it is integral pre-buried in advance, ensure sleeve it is suitable for reading apart from 5~10cm of concrete surface；
3）It is suitable for reading to the pre-buried pvc pipe of concrete surface section in sleeve, and ensure plummet and coaxial with sleeve, work progress carries out sleeve
Mouth, the protection of the pvc pipe mouth of pipe；
4）Clear and coherent pvc pipe and sleeve before the installation of construction in later period equipment, PCV pipe preformed holes are passed through by linkage section, by sleeve and in advance
It is integral to bury part anchoring section connection, carries out construction equipment installation；
5）After construction equipment is removed, the linkage section part of foundation bolt is removed, after cutting pre- indwelling hole wall pvc pipe, by flow-passing surface
Processing design parameter carries out filling out envelope using epoxy resin mortar or pre contract mortar to sleeve and concrete surface preformed hole.
Further, step 1）In, the forward end of described anchoring section is in hook formation.
Further, step 2）In, the caliber of described pvc pipe is more than the diameter of the ground but anchoring section of bolt.
Further, step 3）In, the caliber of described pvc pipe is identical with the footpath outside sleeve.
Beneficial effects of the present invention：
The present invention is that its construction is simple, cost is small compared with common foundation bolt way, and the later stage removes and concrete surface defect
Repair process is easy for construction, and quality can ensure, the influence to hydraulic structure flow-passing surface is small.

Embodiment
Below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, belongs to the scope of protection of the invention.
A kind of construction method of hydraulic structure flow-passing surface pre-embedded anchoring bolts, comprises the following steps：
1）The anchoring section that foundation bolt is processed into concrete and the linkage section two parts being connected on the ground with construction equipment, it is described
The forward end of anchoring section be in hook formation, the equal processed filament tooth in upper end and linkage section both ends termination of anchoring section, and anchoring section
Pass through straight thread reinforced bar sleeve connection with linkage section；
2）According to the pre-buried position of equipment anchor bolt during the building concrete construction at construction equipment arrangement position, will process
Foundation bolt anchoring section and sleeve connection it is integral pre-buried in advance, the caliber of described pvc pipe is more than the anchor of ground but bolt
Gu the diameter of section, ensure that sleeve is suitable for reading apart from 5~10cm of concrete surface；
