Description

A kind of city integrated piping lane temporary plugging method
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 construction method of temporary plugging 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 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. Therefore built piping lane sets to protect inside built piping lane with construction piping lane time interval few then several months, at most several years at a specified future date 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.It is therefore desirable to design a kind of city integrated piping lane temporary plugging method, piping lane is solved by stages The temporary plugging problem at both ends when construction.
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 city integrated piping lane temporary plugging method, which is characterized in that include the following steps:
Step 1 after the completion of waiting for piping lane construction of bottom plates, binds piping lane wall steel bar;
The concrete prefabricated board made is lifted to piping lane and waits for that block-up position carries out assembly by step 2, in prefabricated board and pipe Separation layer is arranged in the position of corridor wall and piping lane top plate contact, and then branch piping lane wall is fixed pre- with roof plate template and with scaffold Making sheet;
Step 3, binding piping lane roof steel bar, pour piping lane wall and concrete roof, in piping lane end 200- inwardly 300mm range interior walls side is arranged variable cross-section and reserves the groove being adapted with prefabricated board end size at variable cross-section;
Step 4, after piping lane walls concrete conserves, while form removal and scaffold, with split bolt and three Tripod support construction fixes prefabricated board;
Step 5 carries out water-proofing treatment at each seam and assembled seam;
Separation layer is geotextiles or flexible material in the step 2, 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.
4 one end of the prefabricated board offers L-type notch, is matched by two L-type notch between two pieces of prefabricated boards mutually spliced It is merged dress, obtains Z-type assembly seam, the prefabricated board other end stretches into fixed in piping lane wall variable cross-section groove.
Variable cross-section is provided projectingly along piping lane wall side wall into piping lane nacelle in the step 3, convenient on piping lane wall The strength and stability of wall is not influenced while reserved groove.
Water-proofing treatment mode in the step 5 is the seam of assembled seam and prefabricated board and wall between prefabricated board Place's setting water-swelling rubber water bar 7.
Piping lane end temporary plugging by the way of subdivision closure, forms nacelle small central bay in both sides in three nacelles Body is big, is fixed by split bolt between contiguous prefabricated plate in the nacelle of both sides, passes through three between contiguous prefabricated plate in central bay body Corner bracket support construction is connected and fixed.
The quantity of split bolt 10 is determined according to the small nacelle height dimension in both sides in piping lane.
Backwater surface side between contiguous prefabricated plate is arranged in piping lane central bay body in the tripod support construction, for fixing Contiguous prefabricated plate, the tripod support construction include the tripod being positioned on piping lane bottom plate, tripod bottom and piping lane bottom Plate is fixed by fixed pedestal, and tripod side is equipped with several small triangle fixed plates close to prefabricated board side, and fixed plate is fitted in phase Adjacent prefabricated board seam crossing, trepanning is reserved in fixed plate, and 12 liang of end bodies of rod of the U-shaped card passed through from the prefabricated board other side pass through small by three It is fixed on tripod by nut 11 after the fixed plate trepanning of angle.
The tripod main body is assembled by the splicing of several cross bars 15, montant 13 and brace 15.
When built piping lane, which need to be done, to be extended, each locking nut is loosened, remove prefabricated board and hangs scene, it is recessed to repair wall Slot.
The invention has the advantages that:
1, temporary plugging will not cause agent structure to be destroyed, and cost is relatively low;
2, the Z-type seam of end set facilitates assembly, the prefabricated board both ends after assembly to be caught in variable cross-section wall when prefabricated board makes Body groove blocks the dismounting work that mode is simple, is convenient for inside later stage piping lane;
3, 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;
4, 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;
5, 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.
