Described plunger adopts hard foam to make.
A kind of job practices that adopts above-mentioned device to carry out pre-buried grouting conduit in the chamber lining concrete:
One, the position mark by the design grout hole goes out the position that need to bury pre-embedment grouting pipe underground on the bedrock surface of chamber side wall and crown;
Two, according to designing requirement binding structure reinforcing bar, in the assembling reinforcement process, make reinforcing bar avoid to bury underground the position of pre-embedment grouting pipe;
Three, pre-embedment grouting pipe is installed;
Four, in pre-embedment grouting pipe, insert plunger, spring and plunger successively, adopt adhesive tape to seal upper orifice after being pressed in the pipe, in order to avoid plunger, spring are deviate from;
Five, after all pre-embedment grouting pipes in the storehouse install, the frame shuttering; After template is preliminary in place, remove the adhesive tape at all pre-embedment grouting pipe mouth of pipe places, the interior plunger of pre-embedment grouting pipe this moment is ejected a part and is close to the surface of template under the effect of spring; The accurate adjustment template is until reach designing requirement;
Six, concreting;
Seven, after concrete strength reaches solidifying phase requirement, with form removable, the plunger at cleaning pre-embedment grouting pipe mouth of pipe place, and the spring in will managing takes out;
Realize the burial and construction of pre-buried grouting conduit in the chamber lining concrete by above-mentioned steps.
In the step 6, notice that in the process of building, vibrate reinforcement is to the protection of pre-embedment grouting pipe.
In the step 3, the end mouth of pipe of pre-embedment grouting pipe aimed at and be close to mark on the batholith face, the pipe shaft of pre-embedment grouting pipe and design grout hole direction are consistent, with iron wire and bar dowel with built-in pipe and structure reinforcing bars colligation/or be welded and fixed.
In the step 4, the plunger that will be positioned at batholith face one side is connected with spring.
Continuing turnover after described plunger and spring reclaim uses.
Pre-buried grouting conduit device in a kind of chamber lining concrete that the utility model provides compared with prior art, has following beneficial effect:
1) by plunger and spring assembly are set in built-in pipe, plunger is under the telescopic action of spring, after the template accurate adjustment is in place, the plunger of pre-embedment grouting pipe nose end always is close to the surface of template and is not produced the gap, the problem of having avoided pre-embedment grouting pipe mouth of pipe position to be covered by the concrete cement slurries, after form removable, the pre-embedment grouting pipe nozzle position is high-visible, thereby solved in the prior art technical barrier that pre-embedment grouting pipe in the chamber lining concrete is difficult to confirm accurate location, the problems that conventional pipe laying method is brought have been overcome, as take time and effort, increase engineering cost, to concrete generation destruction to a certain degree, be unfavorable for workmanship, and strengthened the problems such as workload of later stage repairing.
2) plunger outer diameter of design is slightly less than the pre-embedment grouting pipe internal diameter, in pre-embedment grouting pipe, can move but basic gapless is advisable with plunger, this being designed with is beneficial to that cement grout pours in the pre-embedment grouting pipe when preventing concreting, thereby reduce the some work amount of concrete drill hole, effectively reduced engineering cost.
3) plunger adopts hard foam to make, be conducive to remove quickly and easily, and also with low cost.
The plunger that 4) will be positioned at batholith face one side is connected with spring, specifically can adopt cord, steel wire or direct affixed mode, thereby be convenient to the plunger of batholith face one side is taken out.
