Problems solved by technology

[0002] At present, two construction methods of prefabricated and cast-in-place inspection wells can be used for drainage inspection wells. The problems caused by this are that it is difficult to install pipes after hoisting of prefabricated wells, and the construction progress of cast-in-place wells is slow and the appearance quality is poor.

Abstract

The invention discloses a cast-in-situ and prefabricating combined construction method of a drainage inspection well. The construction method comprises the following steps: producing reinforced concrete prefabricated well walls; installing pipelines in trenches, meanwhile, reserving base plate construction spaces at the bottoms of the pipelines, and casting a bed course after the installation of the pipelines; binding base plate reinforcing steel bars to the upper side of the bed course and erecting base plate formworks, and binding and fixing reserved joint bars and the base plate reinforcingsteel bars after the well walls are lifted; and casting base plate concrete and filling gaps between the pipelines and the well walls, so that the inspection well is molded. According to the cast-in-situ and prefabricating combined construction method of the drainage inspection well provided by the invention, the construction efficiency of the drainage inspection well is improved.

Description

technical field [0001] The invention relates to the technical field of inspection well construction, in particular to a construction method for a drainage inspection well combined with cast-in-place and prefabrication. Background technique [0002] At present, two construction methods of prefabricated and cast-in-place inspection wells can be used for drainage inspection wells. The problems caused by this are that it is difficult to install pipes after hoisting of prefabricated wells, and the construction progress of cast-in-place wells is slow and the appearance quality is poor. Contents of the invention [0003] The main purpose of the present invention is to provide a construction method of a drainage inspection well combining cast-in-place and prefabrication, aiming at improving the construction efficiency of the drainage inspection well. [0004] In order to achieve the above object, the present invention provides a construction method for a drainage inspection well c...
