Description
Technical field
This utility model belongs to anti-floating anchorage technology field, is specifically related to a kind of bottom expanding reach pressure-type Composite Bolt。
Background technology
Anti-float anchor rod is a kind of measure of anti float conventional in all kinds of architectural engineering, and existing anti-float anchor rod is generally made up of parts such as anchor head, muscle body, cast-in-place slip casting anchoring bodys, is generally cast-in-place formation anchoring system, and its construction process is as follows:
(1) plant equipment and material enter job site；
(2) anchor hole location；
(3) rig pore-forming churning reaming；
(4) clear hole；
(5) by anchor pole implant holes, and arrange and anchor pole two grouting pipes side by side；
(6) a pressure pouring cement mortar in anchor hole, cast limit, limit detaches a wherein Grouting Pipe, makes the infiltration water in anchor hole flow out along this pipeline, until whole anchor hole filled by cement mortar；
(7) after slurry initial set, in another pipeline, secondary pressure slip casting is carried out, the space formed after filling up once-cast initial set；
(8) contraction produced by cement mortar after secondary grouting carries out mending slurry。
Commonly use although above-mentioned technique is existing, but still there is problems in that
1) anchoring body is equal diameter, it is impossible to treatment in accordance with local conditions plays the bearing capacity of better soil layer within the scope of rock-bolt length, and economy is poor。
2) when anti-floating requirement for bearing capacity is higher, when adopting soil cement induration, between anchor pole muscle body and anchoring body, there is the risk of fastening invalidation。
Summary of the invention
The purpose of this utility model is in that to provide a kind of easy construction, intensity height, matter measured bottom expanding reach pressure-type Composite Bolt。
Based on above-mentioned purpose, this utility model adopts the following technical scheme that: a kind of bottom expanding reach pressure-type Composite Bolt, the top of described Composite Bolt is by soil cement, the common anchoring section that cement mortar or cement mortar induration are formed, bottom is by peripheral soil cement, cement mortar or cement mortar induration parcel the hollow tubular concrete body of rod with its in set deformed bar or steel strand wires muscle body composition anchoring expanding reach, the bottom of the described hollow tubular concrete body of rod and the bottom connection anchoring expanding reach, the muscle body lower end arranged in hollow tubular concrete frame body is connected to taper base body, taper base body is arranged at hollow tubular concrete post and forms closing, injecting cement paste is irrigated by Grouting Pipe in pipe。
The described hollow tubular concrete body of rod is prefabricated PHA pipe, and wherein the diameter of prefabricated PHA pipe is 150mm～400mm, less than the diameter 5mm ~ 10mm of the common anchoring section in top；The diameter of anchoring expanding reach is be more than or equal to 2 times of prefabricated PHA pipe diameter, and is not less than 450mm。
Little 0.5m～the 1m of length of the length ratio anchoring expanding reach of described prefabricated PHA pipe。
In described prefabricated PHA pipe, injecting cement paste is cement mortar or cement mortar。
The common anchoring section on the top of described Composite Bolt may be configured as free segment。
Compared with prior art, technique effect of the present utility model particularly as follows:
1) adopting the concrete tubular pile body of rod is prefabricated components, can directly use after buying on the one hand；Adopting the mode inserted during construction, compared with in-site pouring anchor rod body, its intensity is higher, and body of rod integrity is more easy to guarantee；
2) lower anchor section, owing to adopting enlarged diameter design, expanding reach length is typically small, is again pressure type anchor rod, anchor pole collateral resistance can be made to be not fully exerted, it is possible to obtain higher bearing capacity；
3) effect of all material plays better, and better economy is in equal diameter pressure type anchor rod, equal diameter tension type anchor pole；
4) anchor pole muscle body is connected with the prefabricated PHA anchoring body end of high intensity, makes muscle body force dispersion in PHA anchoring body and injecting cement paste contact surface, can be prevented effectively from the phenomenon adopting common tension type anti-float anchor rod muscle body with injecting cement paste fastening invalidation。
