Abstract

The invention discloses an inspection well technology, in particular to an integral glass fiber reinforced plastic inspection well; the integral glass fiber reinforced plastic inspection well includes a well body end, a variable diameter well body, connecting branch pipes and a well chamber chute. The end of the well body is set at the uppermost position of the inspection well, and the lower end of the well body is provided with a variable-diameter well body, and the lower end of the variable-diameter well body is provided with a connecting branch pipe and a well chamber chute; the integral type of the present invention FRP inspection well is environmentally friendly, light in weight, simple and convenient to install, high in strength, high in rigidity, good overall shape, good in closed water sealing, corrosion resistant, acid and alkali resistant, smooth surface without scale, small water resistance, and long service life Long and other advantages, suitable for large-scale promotion and application.

Description

Technical field [0001] The invention relates to an inspection well technology, in particular to an integral glass fiber reinforced plastic inspection well. Background technique [0002] Inspection wells are widely used in various commercial, residential and municipal underground pipeline systems, especially underground drainage pipeline systems. The existing inspection wells generally include the following types: (1) brick inspection wells, (2) concrete prefabricated inspection wells , (3) HDPE plastic inspection well. [0003] With the application of new pipes in piping systems, the above-mentioned inspection wells all show some insurmountable shortcomings. (1) The shortcomings of brick inspection wells are: consumption of natural resources, environmental protection, long construction period, labor intensity Large, poor overall shape, poor water tightness, poor corrosion resistance, short service life, etc.; (2) Disadvantages of prefabricated concrete inspection wells: consumptio...

Problems solved by technology

[0003] With the application of new pipes in the pipeline system, the above inspection wells have some insurmountable shortcomings. (1) The disadvantages of brick inspection wells are: consumption of natural resources, not environmentally friendly, long construction period, labor intensity of workers Large size, poor overall shape, poor closed water seal, poor corrosion resistance, short service life, etc.; (2) Disadvantages of concrete prefabricated inspection wells: consumption of natural resources, not environmentally friendly, slow installation, poor closed water seal, poor corrosion resistance, use Short life, etc.; (3) HDPE plastic inspection wells better solve the shortcomings of the first two inspection wells, but because HDPE plastic inspection wells are limited by their own materials and production processes, they have: poor strength and rigidity, and difficulty in large-scale products , Large-scale products will lead to the rapid deterioration of its strength and stiffness; in recent years, with the emphasis on the construction of urban drainage pipe networks in China, the insufficient design capacity of urban drainage pipe networks and the emergence of serious leakage problems in underground drainage pipe networks have prompted New, environmentally friendly, high-performance and large-diameter pipes are widely used in the construction of drainage pipe networks, especially for the application of new large-diameter glass fiber reinforced plastic (glass reinforced plastic) sand pipes

However, in engineering practice, how to select inspection wells matched with large-diameter FRP sand pipes has become an engineering problem. The size of inspection wells made of HDPE plastic is difficult to meet the requirements of large-diameter FRP sand pipes, and HDPE plastic inspection wells The rigidity is difficult to meet the requirements of the large buried depth of the municipal drainage system. At the same time, it is difficult to match the HDPE plastic inspection well interface with the FRP sand pipe interface, and it is difficult to ensure the airtightness of the interface; the use of concrete prefabricated inspection wells can solve the problem that the size of the inspection well meets the large-diameter FRP The requirements of the sand pipe, as well as the strength and stiffness of the inspection well itself meet the requirements of the large buried depth of the municipal drainage system, but the concrete prefabricated inspection well has disadvantages such as poor water sealing, poor corrosion resistance, and short service life.
