Muddy ground area water supply and drainage pipeline burying device

Abstract

The invention relates to a muddy ground area water supply and drainage pipeline burying device comprising mounting top plates, a telescopic connecting frame and a sieve device. The number of the mounting top plates is two, the mounting top plates are provided with mounting holes, the bottom of each mounting top plate is connected with the upper end of the telescopic connecting frame, and the sievedevice is installed between the inner ends of the lower sides of the telescopic connecting frame; and the sieve device comprises a sieve support plate, a shaking sliding column, a shaking spring, a shaking mechanism, a filter screen, a telescopic bracket, a telescopic spring, an extrusion plate, an extrusion mechanism, an extrusion rotating shaft, an extrusion hydraulic cylinder and an extrusionbracket. The muddy ground area water supply and drainage pipeline burying device can solve the problems that during existing pipeline burying, stones in soil need to be manually removed, the soil in apipeline base tank needs to be manually flattened, and the filling height in the pipeline base tank cannot be limited; and the functions that the soil can be automatically screened, and a pipe in thepipeline base tank is automatically buried are achieved.

Description

Technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a device for burying water supply and drainage pipelines in muddy areas. Background technique [0002] Due to the development of urbanization, the renovation projects of water supply and drainage pipes are all over the city and the junction of urban and rural areas. The construction of the pipeline first requires the excavation of the foundation trench. After the foundation trench is leveled, the pipeline is laid in the base trench and the pipeline is connected. The pipeline needs to be pressurized, and the pipeline is qualified and finally the foundation trench needs to be buried. The urban pipeline burying is generally filled with fine sand, and the mud area at the urban-rural junction is generally directly buried with the excavated soil. In the foundation pit, the thickness of the backfilled bottom soil should not exceed 0.3m. The backfilled soil must not contain debr...

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.
