Description
Technical Field
The utility model relates to an underground pipeline, in particular to underground bury prefabricated assembled inspection shaft in pipeline underground.
Background
The existing underground pipeline burying construction process comprises the following steps: firstly, excavating a pipeline laying groove, building inspection wells in the groove after the groove is excavated, then laying pipelines between the inspection wells to enable the pipelines and the inspection wells to be communicated together, and finally backfilling earthwork; the setting method of the inspection well has the defect of low construction speed, and the brick inspection well also has the problems of weak anti-permeability and easy occurrence of peripheral collapse cracks; in addition, the brick inspection well is wet operation, needs more machines and tools, occupies large material stacking area and is not beneficial to field management.
Disclosure of Invention
The utility model provides a prefabricated assembled inspection shaft of concrete for underground buries pipeline underground has solved the slow technical problem that does not have high with well body quality of construction speed that current inspection shaft exists of building by laying bricks or stones.
The utility model discloses a solve above technical problem through following technical scheme:
a prefabricated concrete assembly type inspection well for underground buried pipelines comprises a prefabricated concrete base plate, a prefabricated concrete cylindrical well body and a prefabricated concrete inverted funnel-shaped top well ring, wherein a lower annular rabbet for connecting the well body is arranged on the top end surface of the prefabricated concrete base plate; the prefabricated concrete cylindrical well body is connected with the prefabricated concrete base plate through the butt joint of the annular rabbet of the connecting base plate and the annular rabbet under the connecting well body; the prefabricated concrete inverted funnel-shaped top well ring is connected with the prefabricated concrete cylindrical well body through butt joint of the annular rabbet on the connecting well body and the annular rabbet of the connecting well ring; and the precast concrete base plate, the precast concrete cylindrical well body and the precast concrete inverted funnel-shaped top well ring are butted to form a closed well body.
The upper end of the prefabricated concrete inverted funnel-shaped top well ring is provided with a well cover, a left pipeline is connected to the circular through hole of the left connecting pipeline, and a right pipeline is connected to the circular through hole of the right connecting pipeline.
The utility model discloses a buried pipeline assembly's rapid construction underground, the installation of whole inspection shaft is swift, and the wholeness is good, and impervious ability is strong, the later stage maintenance cost that significantly reduces.
