Non-excavation fiber glass reinforced plastics inspection well and construction method thereof

Abstract

The invention belongs to municipal plumbing equipment, in particular to a non-excavation fiber glass reinforced plastics inspection well assorted with the glass reinforced plastics plumping pipeline and a construction method thereof. The municipal plumbing equipment comprises a glass reinforced plastics pipeline embedded under the ground and an opening of the pipe wall arranged on the upper surface of the glass reinforced plastics pipeline; the opening is communicated with the lower port of a fiber glass reinforced plastics inspection well pipeline; the upper port of the fiber glass reinforced plastics inspection well pipeline is sequentially communicated with an upper well wall, a well seat and a well lid matched with the well seat; the lower port of the fiber glass reinforced plastics inspection well is a U-shaped structure which is matched with the opening of the pipe wall arranged on the upper surface of the glass reinforced plastics pipeline. The construction method comprises process steps such as fiber glass reinforced plastics inspection well sedimentation, connecting the inspection well and glass reinforced plastics pipeline, communicating the lower port of the fiber glassreinforced plastics inspection well and the fiber glass reinforced plastics inspection well pipeline, and the like; the invention solves the problems of difficult construction, high cost and the likeexisting in the prior art and has the advantages of less construction work amount, low cost, small excavation area of road surface.

Description

Technical field [0001] The invention belongs to municipal water supply and drainage installations, in particular to a non-excavation glass fiber reinforced plastic inspection well matched with glass fiber reinforced plastic water supply and drainage pipes and a construction method thereof. Background technique [0002] At present, the pipe jacking construction of FRP sand-filled pipes is widely used in the laying of trenchless underground pipelines, which can facilitate the laying of underground pipelines across roads, railways, and rivers, and is not affected by ground construction traffic, especially in developed cities. It is often the only economic The feasible method is considered to be the best method for modern underground pipeline laying. As the supporting glass fiber reinforced plastic inspection well on the underground pipeline, the following problems exist due to the current installation of the inspection well by excavation: [0003] 1. Large environmental impact...

AI Technical Summary

Problems solved by technology

[0003] 1. Large environmental impact: the installation of inspection wells requires a large amount of earth excavation, the use of large machinery, high cost, and impact on the surrounding environment, especially on the completed road surface and the construction of adjacent buildings.

[0004] 2. Special working conditions: For soft soil foundation, silt, swamp, etc., when the groundwater level is high and the soil is very soft, it is difficult to excavate inspection wells, and the excavation surface is large, which is quite uneconomical
