Abstract

The invention discloses a novel connecting structure of a plastic inspection well and a corrugated pipe, which has a good sealing effect and comprises a well seat and the corrugated pipe, wherein the well seat is provided with a connecting hole which is internally provided with the corrugated pipe; a seal ring is arranged between the connecting hole and the corrugated pipe; an outer wall of the head of the seal ring is provided with a groove; a hole wall of the connecting hole is clamped and sealed with the groove; an inner wall of the head of the seal ring is a cambered surface; the camberedsurface of the seal ring closely wraps a first raised cambered surface at an end part of the corrugated pipe in the connecting hole; and at least one water-stop ring is arranged on the cambered surface of the seal ring and clamped and sealed with the first raised cambered surface at the end part of the corrugated pipe in the connecting hole. The connecting structure has the advantage of good sealing effect and is constructed and installed conveniently.

Description

technical field [0001] The invention relates to a connection structure between an inspection well and an underground pipeline, in particular to a connection structure between a plastic inspection well and a corrugated pipe. Background technique [0002] Inspection wells are used in the outlets, turns, branches, drops, etc. of pipelines such as sewage, drainage, or wiring, for inspection and maintenance, or dredging and cleaning. Due to the cumbersome construction of traditional brick-built inspection wells, which are prone to water leakage and have a short service life, the use of plastic inspection wells will become more and more widespread. The connection structure between the plastic inspection well and the corrugated pipe currently used in the market, such as figure 1 As shown, it includes well base 1, bellows 2, and sealing ring 4. The well base 1 is provided with a connecting pipe 3, the bellows 2 extends into the connecting pipe 3, and a sealing ring is set in the ga...
