Connecting device of drainage pipeline and inspection well

Abstract

The invention discloses a connecting device of a drainage pipeline and an inspection well. The connecting device comprises an annular base plate, an annular upright post and a clamping ring, wherein a waterstop is arranged on the base plate; the first end of the annular upright post is fixedly installed on the base plate, external threads are formed on the upright post, the second end of the upright post is used for being connected with the drainage pipeline, and the upright post and the waterstop are positioned on the same side of the base plate; the clamping ring is matched with the upright post, and internal threads which are matched with the external threads are formed on the inner wall of the clamping ring. During installation, the upright post is installed in the inspection well, and the waterstop on the base plate is positioned between the base plate and the inner wall of the inspection well, so that the problem of permeation is effectively solved. The upright post has the function of the drainage pipeline due to an annular structure, in addition, the external threads on the upright post can be matched with the internal threads on the clamping ring, therefore, gaps do not need to be filled with mortar during installation, and effective installation can be realized only by virtue of thread fitting, thereby simplifying installation steps of the connecting device and improving the installation efficiency.

Description

technical field [0001] The invention relates to the technical field of drainage engineering, in particular to a connection device between a drainage pipe and an inspection well. Background technique [0002] In the drainage project, the gap between the pipeline and the inspection well needs to be treated with anti-seepage. [0003] The existing anti-seepage treatment method for gaps between pipe wells is: using cement mortar, concrete, sealing rings and other materials to fill the gap between the outer wall of the pipe and the inspection well. [0004] In the above-mentioned anti-seepage treatment, the concrete (mortar) filled in the gap between the outer wall of the pipeline and the inspection well is not easy to vibrate and compact, the actual construction effect is poor, and it is easy to seep water during use; and in the actual treatment, it is greatly affected by the construction process and needs to be first To install the pipeline, the inspection well can only be con...

Problems solved by technology

[0004] In the above-mentioned anti-seepage treatment, the concrete (mortar) filled in the gap between the outer wall of the pipeline and the inspection well is not easy to vibrate and compact, the actual construction effect is poor, and it is easy to seep water during use; and in the actual treatment, it is greatly affected by the construction process and needs to be first To install the pipeline, the inspection well can only be constructed after the pipeline installation is completed, the construction requirements are high, and the construction period is long; the anti-seepage treatment process between the pipeline and the inspection well is complicated, the consumption of materials and labor is large, the construction period is long, and the construction cost is high , In addition, the replacement of drainage system pipes is difficult and the maintenance cost is high
