Description
Technical field
The present invention relates to Urban Underground pipe gallery water leakage construction technology, specifically a kind of Urban Underground pipe galleries
Water sealing structure and its construction method at expansion joint.
Background technology
Underground pipe gallery refer to will supply water, drain, electric power, telecommunications, optical cable, heating power, various pipelines such as combustion gas and its attached
Belonging to equipment, selectively concentration is placed within a larger piping lane (or pipe trench).Country is by this facility of pipe gallery
It is defined as the important measure of Creative City infrastructure construction, the people's livelihood engineering that state key is supported, it is intended to crack long-term existence
Urban Underground infrastructure fall behind etc. outstanding problems.Pipe gallery is with bearing capacity is strong, service level is high, saves city soil
Ground resource advocates green construction, reduces the protrusion that urban road excavates, saves Underground Space Resource, improving city guard against disaster ability
Advantage, not only extends that pipeline service life is long, 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 the mark of Municipal Infrastructure modernization.However, it is square higher in many levels of ground water, especially have
The region following the line of the sea of silt mud geological condition complex distribution, even if being provided with rubber fastening band at concrete pipe gallery expansion joint
（Or steel plate water stopper）, but the side generated with the wriggling of underground mud, a large amount of vehicle dynamic loads of earth's surface, Adjacent Buildings
The various aspects combined factors such as differential settlement of pressure and structure influence, and different degrees of mistake can be all caused at piping lane expansion joint
Phenomena such as position, floating, waterstop drawing crack, piping lane expansion joint is caused leak occur, occur " Water Curtain Cave " phenomenon when serious, gives piping lane
The various pipelines in the inside, pipeline bring security risk.
Invention content
The seepy question at above-mentioned piping lane expansion joint, the present invention provides to be stopped at a kind of Urban Underground pipe gallery expansion joint
Water-bound and its construction method, which takes guides leak to reach sealing inside piping lane, and realizes and do not have to again
The purpose that piping lane does construction of waterproof layer again is excavated, water sealing structure material materials aspect, construction is simple, speed are fast, while safety
Reliably, cost-effective, significant effect.
The present invention solve its technical problem the technical solution adopted is that：
Water sealing structure at a kind of Urban Underground pipe gallery expansion joint, including rubber fastening band, gutter, piping lane expansion joint
Place's setting rubber fastening band, the elongated setting gutter in piping lane bottom plate side；It corresponds at expansion joint and sets on the concrete roof of piping lane
Catch basin is set, is corresponded on the both sides concrete wall of piping lane and percolating water diversion trench is respectively set at expansion joint, percolating water diversion trench
V-type expansion joint buckle closure is arranged in outside, and diversion pipe, percolating water water conservancy diversion trench bottom are arranged between catch basin both ends and percolating water diversion trench
Discharge outlet is set, and percolating water is discharged into gutter by discharge outlet through piping lane floor structure.
Further, the catch basin is lifted on by bracket on the concrete roof of piping lane.
Further, the concrete roof expansion joint both sides of piping lane are respectively set fluted, and groove forms drip, top plate
Percolating water drips from drip, comes together in catch basin.
Further, the concrete wall expansion joint both sides of piping lane are respectively set fluted, and water-swellable is housed in groove
Sealing rod, by forming sealing structure between water expandable waterstop and V-type expansion joint buckle closure.
The construction method of water sealing structure, includes the following steps at above-mentioned Urban Underground pipe gallery expansion joint：
（1）It uses stainless steel plate to make catch basin or using concave plastic channel as catch basin, bracket is made with angle steel, use
Stainless steel plate makes V-type expansion joint buckle closure, spare；
（2）At concrete roof expansion joint, both sides certain distance grinding wheel or other cutting implements cutting twice groove are formed
Drip in similar China Democratic National Construction Association, drips from there convenient for top plate percolating water, is unlikely to ooze and goes to outside；
（3）Catch basin is placed on bracket, is then fixed on concrete with the catch basin of setscrew by bracket and thereon
At top board expansion joint, so that the percolating water on concrete roof is passed through drip and flow to catch basin；
（4）Vertical elongated pick in expansion joint is corresponded on concrete wall and digs out a percolating water diversion trench, then in coagulation
Twice groove is respectively cut in cob wall wall expansion joint both sides, and water expandable waterstop is placed in groove；Again in concrete walls wall surface
Fixed V-type expansion joint buckle closure is followed closely with wall, and V-type expansion joint buckle closure is made to compress water expandable waterstop, forms sealing；
（5）Diversion pipe is connected between catch basin and percolating water diversion trench；Cutting is shallow together on the concrete floor of piping lane
Gutter, shallow gutter one end correspond to percolating water diversion trench bottom opening, and the other end extends to the gutter of piping lane bottom plate side；
Alternatively, concrete floor is accomplished certain slope, the water that percolating water water conservancy diversion trench bottom seepage flow gets off is made to be pooled in gutter, by
Gutter flow finally in time excludes the water in sump by intelligent system for monitoring to sump.
Using the present invention of above-mentioned technical proposal, compared with prior art, advantage is：
Present invention obviates the methods of traditional " stifled ", and achieve the purpose that sealing using " leading ".Piping lane both sides coagulation
Cob wall wall expansion joint percolating water is by diversion trench water conservancy diversion, and percolating water is collected and is guided to by catch basin at concrete roof expansion joint
In diversion trench on concrete wall, two parts percolating water flows in land drain together, passes through prison after being pooled to sump
Intelligent drainage system is controlled to exclude.The method not only gathers materials on the spot, is simple and practicable, speed of application is fast, but also input cost is relatively low, effect
Fruit is notable.Avoid it is conventionally employed with it is " stifled " for main construction method bring it is a series of it is long in time limit, task is heavy, costly, anti-
The defects of repairing again.
