Description
Technical field
This utility model is related to the supplementary material of bolt grouting, specifically a kind of group of supporting pile anchor rod secondary grouting
Part, it is adaptable to the construction of deep basal pit or high slope rockmass pile anchor rod architecture.
Background technology
When deep basal pit or high slope carry out supporting using supporting pile structure, generally require and perform anchor pole support pile is carried out
Drawknot, but as the cement mortar of anchor pole has shrinkage characteristicss in hardening solidification, the tension pull out force of anchor pole can be reduced, therefore in anchor pole
Need to carry out secondary grouting by secondary grouting pipe in work progress, to improve the tension pull out force of anchor pole.
Traditional secondary Grouting Pipe typically adopts floral tube, i.e., make cement grout toward slip casting in floral tube with suitable grouting pressure
The cement grouted bolt body of splitting first time slip casting oozes out the space of serosity filling anchor bar body and the soil body, but the method has obvious disadvantage
End：One is the opportunity for being difficult to control to secondary grouting；Two is the pressure for being difficult to control to secondary grouting, if that is, the secondary grouting time is too
Evening, then first time slip casting formation cement grouted bolt body intensity is too high, is difficult to once grouting body thunderclap using intrinsic grouting pressure
Thunderbolt, it is impossible to form secondary grouting passage；And if the slip casting time is too early, then first time slip casting forms cement grouted bolt and has not yet shunk
Entirely, the effect of secondary grouting is not had.It is difficult to hold the opportunity of secondary grouting and the pressure of slip casting in causing practical operation, even if
Be tested to obtain correlation technique control parameter before construction, but due to the buried soil body of anchor pole in, with unobservability, when
Geological state is easily caused the tension pull out force of anchor pole and does not reach design load when complicated, generally require significantly to increase safety stock system
Count and cause to waste.
The content of the invention
The purpose of this utility model is to provide a kind of component of supporting pile anchor rod secondary grouting, can effectively reduce anchor pole two
The technical controlling difficulty of secondary slip casting, improves the efficiency and quality of anchor pole secondary grouting, and makes and simple to operate, cost-effective.
This utility model reaches above-mentioned purpose by employing the following technical solutions：The group of supporting pile anchor rod secondary grouting
Part, including secondary grouting pipe and locating ring, concrete structure and annexation are：If described secondary grouting pipe is by being responsible for and the Heavenly Stems and Earthly Branches
Pipe is constituted, and arm is arranged on supervisor at a certain distance using reducing cross joint, and the locating ring is arranged on each arm
Side, is connected using iron wire colligation with secondary grouting pipe, for once grouting pipe, secondary grouting pipe and anchor cable are positioned at the soil body
In the middle of anchor cable hole.
The supervisor, arm and reducing cross joint are PVC and make.
, for 25mm, length is identical with anchor cable for the caliber of being responsible for.
The branch diameter is 16mm, and length is identical with the outer annular diameter of locating ring.
The reducing cross joint specification turns double 16mm mouths for pair 25mm mouths, and two termination of reducing cross joint longitudinal direction is responsible for,
Transverse ends connect arm, and reducing cross joint setting space is 0.8m-1.2m.
The locating ring is metal concentric ring.
Described locating ring ring interior diameter is 50-60mm, and outer annular diameter is 120-180mm, and outer annular diameter is than soil body anchor cable
The little 30mm in hole.
Described supervisor through locating ring internal ring and fixed with iron wire colligation.
The end of described supervisor is blocked using plug, and the end of arm is blocked using adhesive plaster.
It is of the present utility model to have the prominent advantages that：
1st, having overturned conventional anchor secondary grouting needs the operation principle of thunderbolt once grouting anchor bar body, when making secondary grouting
The selection of machine and the control of grouting pressure are more flexible controllable, it is to avoid need by using test method to determine key technology control
Parameter processed and the height to construction experience are relied on.
2nd, guarantee the uniformity of pulp during secondary grouting, increase substantially the efficiency and quality of secondary grouting, reduce anchor pole
The safety stock coefficient of anti-pulling design load, it is cost-effective.
