Embodiment Construction

[0032] An application of a finished plastic inspection well in an outdoor drainage system (that is, a construction method when the finished plastic inspection well is applied to an outdoor drainage system), including the following construction steps:

[0033] (1) Pit and foundation construction

[0034] (1) The well pit and the pipe trench are excavated at the same time. During the excavation, the main line of the well seat and the pipeline in the pipe trench are on the same axis; the side slope of the well pit is consistent with the side slope of the pipe trench; Digging; if the foundation soil is disturbed, take remedial measures according to the relevant provisions of the current "Code for Construction and Acceptance of Water Supply and Drainage Pipeline Engineering" GB 50268;

[0035] (2) For construction in areas with relatively high groundwater levels or in rainy seasons, drainage and water level reduction measures shall be implemented;

[0036] (3) The inspection well ...

Abstract

The invention discloses application of a finished plastic inspection well in an outdoor drainage system. The application includes the steps of pit and foundation construction, inspection well connecting pipe mounting, shaft mounting, backfilling, well lid mounting, closed water test and the like. The application of the finished plastic inspection well in the outdoor drainage system is convenient to construct and good in construction quality.

Description

technical field [0001] The invention relates to the application of a finished plastic inspection well in an outdoor drainage system. Background technique [0002] The construction speed of existing inspection wells is slow, which has a great impact on the environment and urban traffic, and does not meet the requirements of civilized and rapid construction. The quality stability is poor, and the brick masonry has low strength, especially at the joint between the plastic pipe and the inspection well, which is easy to leak. A research report in Shanghai shows that the cause of the pipeline collapse in the quicksand area is firstly the leakage of the interface, and the second is the damage of the inspection well. Contents of the invention [0003] The object of the present invention is to provide an application of a finished plastic inspection well with convenient construction and good construction quality in an outdoor drainage system. [0004] Technical solution of the pre...
