Abstract
The invention discloses an underground comprehensive pipeline which comprises a pipe body. An opening is formed in the side face of the pipe body. Path channels are arranged in the pipe body in the height direction in a layered manner. The opening is divided by a vertical frame into multiple maintenance holes. Each maintenance hole is provided with an inwards concave step face. Sealing rings are arranged on the step faces. Each maintenance hole is correspondingly provided with a sealing plate, and the sealing plates are embedded into the step faces and are in close fit with the sealing rings. Threaded connecting holes are formed in the step faces, and screw rods penetrate through holes in the sealing plates to be connected with the threaded connecting holes. A laterally open structure is adopted in the opening for maintenance and replacement in the underground comprehensive pipeline, so that the opening is kept away from the upper end where leakage is most likely to happen.
Description
Technical field
The present invention relates to a kind of underground composite duct.
Background technology
The body descending composite duct traditionally generally has opening upwards, and opening part capping is closed.But the opening part of this composite duct is in the upper end that seepage pressure is maximum, and when keeping in repair pipe interior circuit, generally require taking-up of whole capping being sling just can keep in repair, because of maintenance surface the cat's whisker face, pavement excavation area often with can maintenance surface corresponding, usually cannot will increase substantially the pipeline bearing capacity for circuit because excavation area is limited.
Summary of the invention
In order to overcome the deficiencies in the prior art, the technical problem to be solved is to provide a kind of underground composite duct, and the maintenance of this underground composite duct is convenient, and water-impervious performance is better.
The technical solution adopted for the present invention to solve the technical problems is: underground composite duct, including body, body side has opening, described tubular body arranges each line channel along short transverse layering, opening is separated in multiple service hatches by munnion, each service hatch has the step surface of indent, step surface place is provided with sealing ring, each service hatch is correspondingly arranged on closing plate, close plate embed step surface place and with sealing ring close-fitting, described step surface offers threaded connection hole, and screw rod is connected through the through hole closed on plate with threaded connection hole.
In the present invention, in the composite duct of underground, the opening of maintenance and replacing adopts the structure of lateral openings, makes opening part avoid being easiest to the upper-end part of driving of seepage.And when maintenance, can be available for, at pipeline side excavation, the groove that people enters, and closing plate is pulled down and can be keeped in repair, it is not necessary to the upper cover of whole composite duct is lifted and mentions.If needing to improve the circuit bearing capacity of pipeline, only need to strengthen underground composite duct height, it is made to arrange to underground depth, when maintenance, only need to dig downwards deep trench can cover all pipelines needed repairing equally, without needing to excavate whole circuits that sufficiently wide road surface can be keeped in repair in pipeline as the pipeline of tradition upward opening.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
The structural profile schematic diagram of Fig. 1 underground provided by the invention composite duct.
Fig. 2 is the lateral plan of Fig. 1.
Detailed description of the invention
With reference to Fig. 1, shown in Fig. 2, underground provided by the invention composite duct, including body 1, body 1 side has opening, described body 1 is internal arranges each line channel along short transverse layering, opening is separated in multiple service hatches 2 by munnion 10, each service hatch 2 has the step surface 3 of indent, step surface 3 place is provided with sealing ring 4, each service hatch 2 is correspondingly arranged on closing plate 5, close plate 5 embed step surface place 3 and with sealing ring 4 close-fitting, described step surface 3 offers threaded connection hole 6, screw rod 7 is connected through the through hole closed on plate 5 with threaded connection hole 6, with handle 8 on described closing plate 5, closing plate 5 is pulled open during convenient for maintaining.
With reference to shown in Fig. 2, in order to ensure seal, at least provided with three threaded connection holes 6 on described step surface 3, described closing plate 5 is corresponding to be connected through three screw rods 7 with threaded connection hole 6.
With reference to shown in Fig. 1, in order to ensure the firmness of pipe interior, it is to avoid it is crushed by the soil body, in described body 1, segmentation is supported with cylinder 9.
