Abstract
The utility model discloses a plastic inspection well used for leakage detection in the collapsible loess area. The plastic inspection well comprises a well body, an observation tube for leakage detection is longitudinally arranged in the well body, the tube opening at the upper end of the observation tube for the leakage detection is a viewing port, the tube opening at the lower end is communicated with a flow guiding tube transversely arranged, and the flow guiding tube stretched out of the well body wall is communicated with the bottom of a leakage detecting channel. The plastic inspection well both has the blowdown and slag removal functions and the leakage detection function, and the leakage detection is convenient, and the problems that one leakage detection well is required to be arranged independently between two inspection wells in the collapsible loess area, and thereby the manpower, the material resources and the land occupation quantity are increased are solved.
Description
Technical field
The utility model relates to a kind of blowdown manhole, relates in particular to a kind of Collapsible Loess District leak detection plastic inspection well.
Background technology
At present, the manhole as water supply and sewerage pipeline generally adopts plastic inspection well and brick well.Design construction for the Collapsible Loess District drainage pipeline networks, conventional method is to construct the leak detection ditch at the pipeline place, pipeline passes through from the leak detection ditch, and pipeline can not leak into the underground saturated yielding that causes if any seepage then flows into the leak detection ditch, causes danger such as structure foundation cracking.Respectively establish a brick manhole at leak detection ditch and pipeline certain distance two ends, this distance is generally 40m, establishes a leak detection well before the manhole of rear end, needs to check when whether leakage being arranged, and need manually enter the leak detection well and hunt leak.The effect of leak detection well is to check in the leak detection ditch whether pipe leakage is arranged, and can propose the maintenance of construct of reference data, scheme if any seepage more among a small circle in, and manhole is used for blowdown and removing dregs.Adopt above-mentioned design, at two manhole intermediate demands one leak detection well is set separately, occupation of land amount accumulative total is bigger, and leak detection is inconvenient, and has improved installation difficulty, has increased the input of manpower and materials.
In addition, China Patent No. " ZL200620033068.0 " discloses a kind of " plastic inspection well of groove structure ", this plastic inspection well comprises main well body, and is bonding or be welded with arm at the main well body side-wall hole, and arm or welding bonding with the chute in being fixed on manhole is communicated with.But because the manhole of said structure does not have leak detection function, thereby can not be used for Collapsible Loess District.
Summary of the invention
The purpose of this utility model is to overcome existing manhole and is used for the problems referred to above that Collapsible Loess District exists, and a kind of Collapsible Loess District leak detection plastic inspection well is provided.The utility model had both had blowdown and slagging-off function, also had leak detection function, and leak detection is convenient, had solved in Collapsible Loess District, and two manhole intermediate demands are provided with a leak detection well separately, have increased the problem of manpower and materials and occupation of land amount.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of Collapsible Loess District leak detection plastic inspection well, comprise the well body, it is characterized in that: vertically be provided with the leak detection observation tube in the described well body, the leak detection observation tube upper end mouth of pipe is an observation panel, the lower end mouth of pipe is communicated with the mozzle of horizontally set, and mozzle stretches out the well body wall and is communicated with leak detection ditch bottom.
When described mozzle was communicated with the leak detection ditch, mozzle mouth of pipe bottom flushed with leak detection ditch bottom or is lower than leak detection ditch bottom, and the leakage water in the leak detection ditch can in time be flowed in the mozzle, has guaranteed the accuracy of leak detection.
Arm on the described well body be arranged on the blow-off pipe of leak detection in the ditch and be communicated with.
Described observation panel place is provided with seal cover, can prevent that the aqueous reflux in the plastic inspection well from advancing concrete leak detection ditch.
Described mozzle passes leak detection ditch sealed wall and is communicated with the leak detection ditch, and the junction is provided with sealing ring, has prevented that the water in the leak detection ditch from revealing.
Described plastic inspection well is straight tube well or closing in well, and is various informative, strengthened applicability.
Advantage of the present utility model is:
1, the utility model had both had blowdown and slagging-off function, also had leak detection function, and leak detection is convenient, had solved in Collapsible Loess District, and two manhole intermediate demands are provided with a leak detection well separately, have increased the problem of manpower and materials and occupation of land amount.
When 2, mozzle was communicated with the leak detection ditch, mozzle mouth of pipe bottom flushed with leak detection ditch bottom or is lower than leak detection ditch bottom, and the leakage water in the leak detection ditch can in time be flowed in the mozzle, has guaranteed the accuracy of leak detection.
3, be provided with seal cover at the mouth of pipe place of leak detection observation tube, can prevent that the aqueous reflux in the plastic inspection well from advancing concrete leak detection ditch.
4, the mouth of pipe of leakage observation tube is " observation panel ", can be by should " observation panel " judging that leak detection ditch and pipeline have leakproof, and it is simple and convenient to hunt leak.
5, mozzle passes leak detection ditch sealed wall and is connected with the leak detection ditch, and the junction is provided with sealing ring, has prevented the water leakage that the leak detection ditch is interior.
6, plastic inspection well is straight tube well or closing in well, and is various informative, strengthened applicability.
