Municipal drain well change-over device

Abstract

The invention discloses a municipal drainage well transfer device, which mainly includes a cylindrical outer cylinder body and a disc-shaped base. The opening of the upper end of the cylinder is provided with a plurality of ground grooves, and the ground grooves are used to realize the docking with the structure of the ground trenches, thereby introducing sewage into the outer cylinder, and the bases are arranged at intervals directly below the outer cylinder. There is no need to adjust when the base is fixed. After the main body of the device is fixed or the sewer structure is formed, the angle of the drain pipe can be adjusted by rotating the drum, and then the drain pipe can be connected to the sewer, and then the entire drain pipe can be realized by injecting concrete. The landfill and fixation of the device is very convenient for the overall installation, and the efficiency is high. There will be no angle deviation in the later stage and need to be re-fixed. At the same time, the overall casting structure is adopted, so the installation efficiency is high.

Description

technical field [0001] The invention relates to the field of drainage wells, in particular to a municipal drainage well transfer device. Background technique [0002] The main function of the drainage well is to collect rainwater from the road surface (or city square). It collects the rainwater and discharges it to the rainwater pipe under the road (that is, the sewer), which can effectively prevent the road surface from accumulating. Condition. [0003] Drainage wells are generally built with concrete and bricks. The overall construction takes a certain amount of time, and the outlet pipe of the drainage well needs to be accurately connected with the sewer in advance. This requires stricter construction requirements. Drainage wells will appear later When the outlet pipe and the sewer cannot be connected, the drainage well needs to be re-constructed, which is not only very troublesome, but also very ineffective. Contents of the invention [0004] In order to overcome the...
