Abstract
Disclosed are an embedded grout pipe device in lining concrete of a chamber and a construction method. The embedded grout pipe device comprises an embedded grout pipe used for being embedded in the concrete, a spring is arranged in the embedded grout pipe, and plungers are arranged at two ends of the spring and are close to orifices of the embedded grout pipe. The diameter of each plunger is slightly smaller than the inner diameter of the embedded grout pipe, so that the plunger can slide in the embedded grout pipe while the concrete cannot flow into the embedded grout pipe. A combination of the plunger and the spring is arranged in the embedded pipe, the plunger at the orifice ends of the embedded grout pipe always cling to the surface of a formwork without a gap after the formwork is accurately adjusted in place, the problem that orifices of an existing embedded grout pipe are covered by cement grout of concrete is avoided, the orifices of the embedded grout pipe are clearly visible after the formwork is detached, and accordingly the technical problem that the existing embedded grout pipe in lining concrete of a chamber in the prior art is accurately positioned difficultly is solved.
Description
Technical field
The present invention relates to embedded part construction field in the concrete, be specifically related to pre-buried grouting conduit device and job practices in a kind of chamber lining concrete.
Background technology
In chamber lining concrete engineering, generally all be designed with backfill, the grout hole such as fixed, do not destroy the structure reinforcing bars in the concrete when holing in order to make, need to be in concrete pre-buried grouting conduit, this kind pre-embedment grouting pipe mostly is greatly iron pipe, must before concreting, install, fixing, after concreting, hole again, grouting construction.When the built-in pipe installation, the built-in pipe mouth of pipe and template contact position often are reserved with certain gap, so that the precision of adjusting template, yet after concreting, gap location is by the cement grout filling, hidden the built-in pipe mouth of pipe, operating personnel are difficult to find its accurately position, in this case, usually adopt the treatment measures of finding out built-in pipe behind air drill or the artificial chisel skim-coat concrete.In real work, not only take time and effort, increase engineering cost, and concrete has been produced destruction to a certain degree, be unfavorable for workmanship, also strengthened the workload of later stage repairing.
Summary of the invention
Technical problem to be solved by this invention provides pre-buried grouting conduit device and job practices in a kind of chamber lining concrete, is convenient to confirm behind the concreting position of pre-embedment grouting pipe.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: pre-buried grouting conduit device in a kind of chamber lining concrete, comprise be used to the pre-embedment grouting pipe that is embedded in the concrete, be provided with spring in the described pre-embedment grouting pipe, the two ends of spring are provided with plunger in the position near the pre-embedment grouting pipe mouth of pipe.
The diameter of described plunger is slightly less than the internal diameter of pre-embedment grouting pipe, so that plunger can slide in pre-embedment grouting pipe, and concrete can't enter.
One end of described pre-embedment grouting pipe also is provided be used to the adhesive tape that prevents that plunger is ejected.
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 and job practices in a kind of chamber lining concrete provided by the invention compared with prior art, have 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.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
