Description

Technical Field

[0001] The utility model relates to the technical field of building engineering facilities, in particular to an anti-seepage and leak detection pipeline structure. Background Art

[0002] For buildings constructed on collapsible loess sites, when various water-filled pipes such as underground water supply and drainage are buried in protective

[0003] When within the range, in order to prevent water leakage from the pipeline from causing the foundation to become wet and deformed, endangering the safety of the building, the pipeline needs to be included in the leak detection facilities.

[0004] The working principle of the leak detection facility is: when leakage occurs in the pipeline in the leak detection ditch, the leaking water is intercepted by the leak detection ditch to prevent it from seeping into the soil; the leakage flows into the leak detection well along the longitudinal slope of the ditch; when water accumulation is observed in the leak detection well, it indicates that the pipeline is leaking and maintenance work should be carried out immediately; the management personnel promptly remove the water accumulated in the leak detection well, enter the leak detection ditch or open the ditch cover to check and deal with the pipeline leaks.

[0005] At present, the leak detection facilities commonly used in engineering projects are reinforced concrete leak detection trenches + leak detection wells. They are composed of reinforced concrete leak detection trenches (collecting pipeline leakage water into leak detection wells, and channels for repairing pipelines), reinforced concrete leak detection wells (collecting / observing pipeline leakage, and the entrance and exit for maintenance personnel to enter the leak detection trench). This technology has a complex structure, high cost, great construction difficulty, and long construction period; it occupies a large space and has many conflicts with underground structures such as ground beams and foundations. It is not applicable when the pipeline is a straight section, the number of pipes is large and concentrated, and the frequency of dredging or repair is low. Utility Model Content
