Description

Water sealing structure and its construction method at Urban Underground pipe gallery expansion joint
Technical field
The present invention relates to Urban Underground pipe gallery water leakage construction technology, specifically a kind of Urban Underground pipe gallery Water sealing structure and its construction method at expansion joint.
Background technology
Underground pipe gallery refers to various to water supply, draining, electric power, telecommunications, optical cable, heating power, combustion gas etc. pipelines and its attached Genus equipment is selectively concentrated and is placed within a larger piping lane (or pipe trench).Country is by this facility of pipe gallery It is defined as the Important Action of Creative City infrastructure construction, the people's livelihood engineering that state key is supported is it is intended to crack long-term existence Urban Underground infrastructure fall behind etc. outstanding problem.Pipe gallery has that bearing capacity is strong, service level is high, saves city soil Ground resource, advocate green construction, reduce urban road excavate, save Underground Space Resource, improve city guard against disaster ability prominent Advantage, not only extends pipeline long service life, and Maintenance and Repair expense is low, and efficient administration solves Urban Traffic Jam Based, But also bring huge social benefit and environmental benefit.Therefore pipe gallery represents City Buried Pipeline construction and development Direction, is one of mark of Municipal Infrastructure modernization.However, in many levels of ground water side higher, particularly having The region following the line of the sea of silt mud geological condition complex distribution, even if be provided with rubber fastening band at concrete pipe gallery expansion joint (or steel plate water stopper), but it is as the wriggling of underground mud, a large amount of vehicle dynamic load of earth's surface, the side of Adjacent Buildings generation The each side combined factors such as differential settlement of pressure and structure affect, and all can cause different degrees of mistake at piping lane expansion joint The phenomenons such as position, floating, waterstop drawing crack, lead to piping lane expansion joint leak, " Water Curtain Cave " phenomenon, to piping lane when serious The various pipeline in the inside, pipeline bring potential safety hazard.
Content of the invention
Seepy question at above-mentioned piping lane expansion joint, the present invention provides and stops at a kind of Urban Underground pipe gallery expansion joint Water-bound and its construction method, this water sealing structure takes guiding leak inside piping lane to reach sealing, and realizes without again Excavate the purpose that piping lane does construction of waterproof layer again, water sealing structure material is drawn materials, and aspect, construction be simple, speed is fast, safety simultaneously Reliable, cost-effective, effect is significant.
The present invention solves its technical problem and the technical scheme is that
Water sealing structure at a kind of Urban Underground pipe gallery expansion joint, including rubber fastening band, gutter, piping lane sets at expansion joint Put rubber fastening band, piping lane base plate side elongated setting gutter;Setting collection at corresponding expansion joint on the concrete roof of piping lane Tank, the both sides concrete wall of piping lane is respectively provided with percolating water guiding gutter, outside percolating water guiding gutter at corresponding expansion joint Setting V-shaped expansion joint buckle closure, arranges mozzle between water leg two ends and percolating water guiding gutter, percolating water water conservancy diversion trench bottom is arranged Discharge outlet, percolating water enters gutter by discharge outlet through piping lane base arrangement.
Further, described water leg is lifted on the concrete roof of piping lane by bracket.
Further, the concrete roof expansion joint both sides of piping lane are respectively provided with fluted, groove formation drip, top board Percolating water drips from drip, comes together in water leg.
Further, the concrete wall expansion joint both sides of piping lane are respectively provided with fluted, and groove is built with water-swellable Sealing rod, by forming sealing structure between water expandable waterstop and V-shaped expansion joint buckle closure.
At above-mentioned Urban Underground pipe gallery expansion joint, the construction method of water sealing structure, comprises the steps:
(1) make water leg or using matrix plastic channel as water leg with corrosion resistant plate, make bracket with angle steel, with stainless Steel plate makes V-shaped expansion joint buckle closure, standby;
(2) concrete roof expansion joint both sides certain distance emery wheel or other cutting implements cutting twice groove formed similar Drip in China Democratic National Construction Association, is easy to top board percolating water and drips from there, is unlikely to ooze and goes to outside;
(3) water leg is placed on bracket, then with setscrew, bracket and water leg thereon is fixed on concrete roof At expansion joint, the percolating water on concrete roof is made to flow to water leg by drip;
(4) vertically elongated picking digs out a percolating water guiding gutter, then in concrete walls to correspond to expansion joint on concrete wall Wall expansion joint both sides are respectively cut twice groove, place water expandable waterstop in groove;Again in concrete walls wall surface wall Nail fixing V-shaped expansion joint buckle closure, and make V-shaped expansion joint buckle closure compression water expandable waterstop, form sealing;
(5) it is connected mozzle between water leg and percolating water guiding gutter;Cutting shallow draining together on the concrete floor of piping lane Ditch, shallow gutter one end corresponds to percolating water guiding gutter bottom opening, and the other end extends to the gutter of piping lane base plate side;Or Person, concrete floor is accomplished certain slope, so that the water that percolating water water conservancy diversion trench bottom seepage flow gets off is pooled in gutter, by arranging Ditch flow to sump, finally the water in sump is excluded in time by intelligent system for monitoring.
Using the present invention of technique scheme, compared with prior art, its advantage is:
The method that present invention obviates traditional " blocking up ", and adopt " leading " to reach the purpose of sealing.Piping lane both sides concrete walls Wall expansion joint percolating water by guiding gutter water conservancy diversion, at concrete roof expansion joint, collected by water leg and be guided to coagulation by percolating water In guiding gutter on cob wall wall, two parts percolating water flows in land drain together, passes through to monitor intelligence after being pooled to sump Can drainage system exclusion.The method not only gathers materials on the spot, simple, speed of application is fast, and input cost is relatively low, effect shows Write.Avoid conventionally employed a series of long in time limit, the task brought with " blocking up " for main construction method again, costly, repeatedly to tie up The defect such as repair.
