Example Embodiment

[0023] like Figure 1-Figure 3 As shown in the figure, a specific embodiment of the prefabricated and assembled pipeline combination well of the present invention includes four prefabricated pipe sections 1 connected by flexible sockets, and the joints of two adjacent prefabricated pipe sections 1 are placed into a sealing member. Double O-rings for flexible socket connection. Each prefabricated pipe section 1 is spliced ​​in sequence to form a pipeline combined well structure. The cross section of the prefabricated pipe section 1 in the present invention is oval.

[0024] like figure 2 As shown in the figure, the side wall of the prefabricated pipe section 1 is provided with reserved access holes, specifically, the pre-buried 6-hole DN150 information hole 2, the pre-buried DN100A type rigid waterproof casing 3, the pre-buried 6-hole DN150 power hole 4, Pre-embedded DN200A type rigid waterproof casing 5, for pipes and cables to enter and exit.

Abstract

The invention discloses a precast assembled pipeline combined shaft, which comprises at least two precast pipe sections, wherein a sealing element is arranged at the joint of the adjacent precast pipe sections; the cross section of each precast pipe section is elliptic; a steel water collecting pit and a drainage ditch are arranged at the bottom of the precast pipe sections; each precast pipe section comprises a partition wall for partitioning a passage into a first passage and a second passage; and each precast pipe section is provided with a prepared hole through which a pipeline and a cable get in and out. The precast pipe sections are assembled into the pipeline combined shaft, so that the quality of the pipeline combined shaft is ensured, and the pipeline combined shaft is high in non-uniform settling resistance and quick in construction. By adopting the precast pipe sections of which the cross sections are elliptic, the sealing effect between the adjacent precast pipe sections is good, and the utilization rate of the internal space of each precast pipe section can also be improved.

Description

technical field [0001] The invention relates to the technical field of pipeline combination wells, in particular to a prefabricated assembled pipeline combination well for an underground comprehensive pipeline gallery. Background technique [0002] In order to implement unified planning, design, construction and maintenance, the municipal public facilities built underground in the city for laying municipal public pipelines are called comprehensive pipe corridors. The existing comprehensive pipe gallery is equipped with various pipeline combination wells to realize the functions of pipelines entering and leaving the plot, such as setting up feeding wells for realizing pipeline installation and hoisting functions; setting up air inlet wells for realizing air inlet functions; Drainage wells are provided; personnel entrances and exits or escape holes are provided to realize the function of personnel entry and exit. In the existing comprehensive pipe gallery project, the pipelin...
