Description

A kind of bolt fixes the piping lane port temporary plugging method of prefabricated board
Technical field
The present invention relates to underground pipe gallery segmentation or when stage construction, piping lane blocking technology field, and in particular to a kind of Piping lane carries out the piping lane port temporary plugging method that bolt fixes prefabricated board by close end.
Background technology
In recent years, Urban Underground pipe gallery has become the one of the important signs that of civilian infrastructure modernization construction.City City's underground pipe gallery be it is a kind of modernization, scientific, intensive urban infrastructure, by electric power, natural gas, communication, give The two or more pipe installation such as water, refrigeration is to the following the same space of road.Advantageously account for road surface excavate repeatedly, pipeline maintainance The problems such as difficult and aerial hanging wire is intensive, realizes the centralized management and maintenance to urban pipeline.Therefore, city integrated piping lane construction There are realistic meanings for the further investigation popularization of technology and method.
Since the period of city integrated piping lane construction is long, range is wide, of high cost, the more phases construction of piping lane point under normal conditions. Built piping lane builds piping lane time interval few then several months, at most several years at a specified future date.Therefore, it is set inside built piping lane to protect It is standby, and ensure that normal operation is unaffected, temporary plugging is carried out to built piping lane both ends.It first has to consider to block when closure The relationship of wall and agent structure cannot destroy agent structure, remove conveniently, it is ensured that plugging structure safety, while to take into account envelope The practicability and cost of blocking method.
Invention content
In view of the problems of the existing technology, the present invention is the technical solution for solving problems of the prior art and using It is as follows:
A kind of bolt fixes the piping lane port temporary plugging method of prefabricated board, which is characterized in that includes the following steps:
Step 1, after piping lane bottom plate completes, piping lane wall steel bar is bound, in piping lane end to be blocked inwardly 200 Groove and embedded water stop screw rod are reserved on~300mm range inner walls;
Several concrete prefabricated boards made are lifted the pre-buried groove location into step 1 by step 2, will after assembled Vertical piece passes through split bolt locked and fixed between contiguous prefabricated plate;
Step 3, prefabricated board upper surface and side end face setting separation layer after, branch piping lane wall and roof plate template, with support Frame is fixed;
Step 4, binding piping lane roof steel bar, pour piping lane wall and concrete roof;
Step 5 waits for form removal after the completion of the maintenance of piping lane walls concrete, and sealing up screw pre-buried in wall is penetrated prefabricated board It is fastened after upper hole;
Step 6 carries out water-proofing treatment at each seam and assembled seam.
The sealing up screw is Three-section water stop screw rod, is reinforcing bar sealing piece in the middle part of Three-section water stop screw rod, three-stage is stopped Water screw rod is connected with sleeve for fixing overhanging screw rod close to wall end, and overhanging screw rod is for fixing prefabricated board and wall.
Described prefabricated board one end offers L-type notch, and the other end offers prefabricated board by close end both sides and reserves groove, and two It is assembled by two L-type notches fits between the prefabricated board that block mutually splices, Z-type assembly seam is obtained, prefabricated board is reserved groove and used In being fixed with nut after sealing up screw.
Separation layer is geotextiles or flexible material in the step 3, and prefabricated board and follow-up casting concrete are separated, kept away Exempt from prefabricated board and pours the dismounting for facilitating follow-up prefabricated board together with cast-in-place concrete.
Water-proofing treatment mode in the step 6 is between prefabricated board between assembled seam and prefabricated board and piping lane wall Water-swelling rubber water bar is arranged in seam crossing.
The quantity of the sealing up screw and split bolt is determined according to piping lane inside dimension.
When built piping lane, which need to be done, to be extended, each locking nut is loosened, remove prefabricated board and hangs scene, repairs wall spiral shell Keyhole.
The invention has the advantages that:
1, temporary plugging will not cause agent structure to be destroyed, and cost is relatively low;
2, reserved " Z " type piece prevents Groundwater infiltration indirectly when prefabricated board makes;Pre-buried three-stage in piping lane wall Sealing up screw passes through the fixed form of prefabricated board groove simple, is to remove in the later stage to provide facility inside piping lane;
4, water-swelling rubber water bar is set in prefabricated board and with corridor body seam crossing, can ensures that both ends will not leak Water;
5, temporary plugging is carried out to built piping lane both ends early period, does not influence the normal operation of piping lane, and effective protection Piping lane inner facility;
6, when future needing to extend, need to only come loose built piping lane nut, remove prefabricated board, and method is simple, implement Property is strong.
