Abstract
The utility model discloses a sewage inspection shaft for preventing road surface collapse, which consists of a concrete foundation, a brick-built sewage well body, a sewage pipe, a geosynthetic material with good filtering performance and a fastening ring, wherein the geosynthetic material with good filtering performance is pasted and wrapped outside the brick-built sewage well body; the geosynthetic material with good filtering performance is fixedly arranged at the periphery of the sewage pipe by the fastening ring. When underground water or water pipe leaks and flows in through the damaged hole of the sewage well wall, the geosynthetic material with good filtering performance plays a role, and soil particles wrapped by water flow are prevented outside the sewage well, so that the roadbed can be prevented from being hollowed gradually, and the pavement is guaranteed not to collapse. The utility model discloses a prevent sewage inspection shaft that road surface sinks, simple structure, construction convenience, the cost-push is few, and the protecting effect is good, and economic benefits is huge with social.
Description
Technical field
The utility model belongs to field of urban drainage, specifically a kind of sewage water inspection well preventing road surface from subsiding.
Background technology
Inspection shaft be used in drainage pipe turning, branch, the place such as to fall so that check, the well of dredging.Usually in concrete foundation, lay bricks into well, for ensureing inspection shaft quality, the full filling of code requirement brickwork joint mortar, Jing Tineiwaibi adopt 1:2 cement mortar to wipe one's face.Because urban sewage pipe is arranged on below road mostly, vehicle for years passes through, and the inspection shaft borehole wall is easy to occur crack, hole, soil pipe and well body contact position the weakest.Under secondary city, Hangzhou, sand all can occur that road surface subsides every year, and little then tens square metres, greatly then up to a hundred meters of length road surfaces subside, cause any property loss, casualties, because of road trimming, government drops into a large amount of manpower and materials again, hundreds of thousands at least, slightly larger road surface subsides rehabilitation cost just up to up to a million.Trace it to its cause, this region is formed by enclosing and cultivating, soil layer based on silt, when underground water or aqueduct leak flow into via the damaged hole of the sewage borehole wall time, silt particle pulls and takes away by the penetration that seepage flow produces, increase roadbed in time gradually to be emptied, the process that soil particle is pulled away occurs in below road surface and sink hole, is not easily found, and because of the roof system effect on road surface, also can not be found when roadbed cavity is less, until roadbed is emptied on a large scale, road surface subsides.Other cities also often occur that the road surface that same cause causes subsides.
Utility model content
In order to solve the above-mentioned technical problem existed in prior art, the utility model provides a kind of sewage water inspection well preventing road surface from subsiding, be made up of concrete foundation, brick sink hole well body, soil pipe, geosynthetics that strainability is good, dead ring, the geosynthetics that described strainability is good pastes and is rolled in the brick external side of sink hole well.
Further, the geosynthetics that described strainability is good is fixedly installed on soil pipe periphery by dead ring.
When underground water or aqueduct leak hole inflow damaged via the sewage borehole wall, the geosynthetics that strainability is good plays a role, and the soil particle that current are swept along is stopped in outside sink hole, and roadbed can be avoided to be emptied gradually, ensures that road surface does not subside.A kind of sewage water inspection well preventing road surface from subsiding of the present utility model, structure is simple, easy construction, and cost increases few, and protection effect is good, economic benefit and social benefit huge.
Accompanying drawing explanation
Fig. 1 is a kind of sewage water inspection well generalized section preventing road surface from subsiding.
Detailed description of the invention
Below in conjunction with accompanying drawing, utility model is described further.
As shown in Figure 1, a kind of sewage water inspection well preventing road surface from subsiding of the present utility model, be made up of concrete foundation 1, brick sink hole well body 2, soil pipe 3, geosynthetics 4 that strainability is good, dead ring 5, the geosynthetics 4 that strainability is good pastes and is rolled in outside brick sink hole well body 2.It is peripheral that the geosynthetics 4 that strainability is good is fixedly installed on soil pipe 3 by dead ring 5.
When a kind of sewage water inspection well preventing road surface from subsiding uses, when underground water or aqueduct leak hole inflow damaged via the sewage borehole wall, the geosynthetics that strainability is good plays a role, the soil particle that current are swept along is stopped in outside sink hole, avoid roadbed to be emptied gradually, ensure that road surface does not subside.
