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 present invention relates to a plastic inspection well for water supply and drainage, in particular to a combined closed-enhanced 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. Plastic inspection wells with reliable connections, less leakage and environmental protection are used, and they are basically integral plastic inspection wells. There are also combined plastic inspection wells. According to some relevant reports on applications and patents, the advantages of combined plastic inspection wells are that they are easy to transport, and it is possible to use injection molding for large-scale wells. The disadvantage is the connection strength and connection sealing problems. [0003] The combined plastic inspection wells that have been reported and published include the "pipe-type inspection well" with the application number "20...
