A device for burying water supply and drainage pipelines in muddy areas

Abstract

The invention relates to a burying device for water supply and drainage pipelines in a mud area, which includes an installation top plate, a telescopic connecting frame and a filter and screen device. The bottom is connected with the upper end of the telescopic connecting frame, and the filter screen device is installed between the lower inner ends of the telescopic connecting frame; the filter screen device includes a filter screen support plate, a shaking sliding column, a shaking spring, a shaking mechanism, Filter screen, telescopic support, telescopic spring, extruding plate, extruding mechanism, extruding rotating shaft, extruding hydraulic cylinder and extruding bracket. The present invention can solve the problems existing in the burial of existing pipelines, such as the need to manually remove the stones in the soil, the soil in the pipeline foundation groove needs to be manually flattened, and the filling height in the pipeline foundation groove cannot be limited, etc., and can realize It can automatically screen the soil and automatically bury the pipeline in the pipeline foundation groove.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a water supply and drainage pipeline burying device in a mud area. Background technique [0002] Due to the development of urbanization, the reconstruction projects of water supply and drainage pipes are all over the city and the urban-rural junction. The pipeline construction first needs to excavate the foundation trench. After the foundation trench is leveled, the pipeline is laid in the foundation trench and the pipeline is connected. It is necessary to carry out a pressurization test on the pipeline, and finally the foundation trench needs to be buried if the pipeline is qualified. In urban pipeline burial, it is generally filled with fine sand, and in the muddy area at the urban-rural junction, the excavated soil is generally buried directly. In the foundation pit, the thickness of backfilling bottom soil shall not exceed 0.3m, and the backfilling soil shall no...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a burying device for water supply and drainage pipelines in muddy areas, which can solve the problems that existing pipelines need to be manually removed from the soil when the existing pipelines are buried, and the soil in the pipeline foundation groove needs to be manually removed. It can automatically screen the soil and automatically bury the pipelines in the pipeline foundation groove. It can mechanize the removal of stones in the soil, The soil in the pipeline foundation groove is automatically leveled, and the filling height in the pipeline foundation groove can be limited, etc.
