Abstract

The invention discloses a combined shrunk-enhanced plastic manhole comprising a well body and a well block. The well body comprises a shrunk well body and a cylindrical well body connected with the shrunk well body; the well body is in two-layered structure and comprises an inner well body and an outer well body; the outer well body has a round cross section; and the inner well body has a cross section in a longitudinal raised-line structure and is connected with the outer well body. The invention adopts a combined structure, has high connection strength and reliable sealing, not only saves molding materials, but also ensures the manhole strength and solves the problems of sealing, transportation, cost and strength of the manhole.

Description

technical field [0001] The invention relates to a plastic inspection well for water supply and drainage, in particular to a combined closed mouth reinforced plastic inspection well. Background technique [0002] For the drainage and sewage pipeline system, many areas in China have banned the use of brick inspection wells, and adopted plastic inspection wells with reliable connections, less leakage, and environmental protection, and basically integral plastic inspection wells, combined plastic inspection wells are also available. According to some related reports on applications and patents, the advantage of the combined plastic inspection well is that it is easy to transport, and it is possible to process large wells in sections by injection molding technology; the disadvantage is the connection strength and connection sealing problems. [0003] The reported and disclosed combined plastic inspection wells such as the "pipe fitting type inspection well" with the application n...
