Abstract
The utility model relates to an inspection well for sewage disposal and water drainage, in particular to a large-aperture plastic pipeline integral inspection well, which comprises a plastic vertical shaft. A plastic transverse connecting drum is connected to the lower portion of the vertical shaft, the transverse connecting drum is provided with at least two adapting openings or insertion openings connected with liquid drainage pipelines, the inner peripheral sections of both the vertical shaft and the transverse connecting drum are circular, the inner diameter of the vertical shaft ranges from 800mm to 2500mm, and the inner diameter of the transverse connecting drum ranges from 300mm to 4000mm. Compared with the prior art, the inspection well has the advantage of extremely simple construction and lower construction cost due to the fact that the vertical shaft can be welded with transverse connecting drums of different sizes and angles in a matching manner according to the actual size and the actual angle of a sewage disposal and water drainage pipeline in a construction site, no seepage at connection positions since the inspection well, the sewage disposal and water drainage pipeline are all made of plastic pipes, and longer service life capable of reaching 50 years.
Description
Technical field
The utility model relates to the manhole of a kind of blowdown, drainage pipe inspection usefulness, is meant the integrated manhole in heavy-caliber plastic pipe road especially.
Background technology
The manhole that uses in the prior art is generally brick manhole or concrete prefabricated manhole, and all there are a lot of shortcomings in these two kinds of manholes.Such as brick well, be to lay corresponding draining blow-off line at the construction field (site) earlier by the workman, and then pile up around pipeline with fragment of brick at the scene according to the size of draining blow-off line and the connected mode of pipeline, there is following shortcoming: the one, efficiency of construction is low, construction period is longer, the wasting manpower and material resources; The 2nd, when line size was big, floor space was bigger during construction, and the engineering time is longer, production, life around the influence construction; The 3rd, fragment of brick is difficult to mate with the shape of pipeline, at interface seepage takes place easily, and the life-span is shorter.Concrete prefabricated for another example manhole is prefabricated finishing in factory, assembles at the construction field (site) and is connected, and has following shortcoming: the one, and its on-the-spot mobility is poor, can't adapt to the Iterim Change of line size; The 2nd, be difficult to mate with the shape of pipeline, seepage takes place easily at interface, the life-span is shorter.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming of prior art, provides the large-bore plastics pipeline integrated manhole, applicable to draining, the blow-off line of various sizes.
The utility model adopts following technical scheme:
The integrated manhole of large-bore plastics pipeline, comprise the vertical pit shaft of a plastics system, the bottom of this vertical pit shaft is connected with the horizontal connecting cylinder of a plastics system, this horizontal connecting cylinder has at least two birdsmouths that link to each other with Drainage pipe or socket, the cross section of the internal diameter of this vertical pit shaft and this horizontal connecting cylinder is circle, the internal diameter of this vertical pit shaft is 800-2500mm, and the internal diameter of this horizontal connecting cylinder is 300-4000mm.
According to a better embodiment of the present utility model, described vertical pit shaft is welded on the described horizontal connecting cylinder.
According to a better embodiment of the present utility model, the outer wall of described vertical pit shaft is formed with the scroll ribs or forms level and smooth real wall.
According to a better embodiment of the present utility model, the outer wall of described horizontal connecting cylinder is formed with the scroll ribs or forms level and smooth real wall.
According to a better embodiment of the present utility model, described vertical pit shaft is a high density polyethylene pipe.
According to a better embodiment of the present utility model, described horizontal connecting cylinder is a high density polyethylene pipe.
According to a better embodiment of the present utility model, in the birdsmouth of described horizontal connecting cylinder, be provided with electric fuse.
The integrated manhole of large-bore plastics pipeline of the present utility model in use, at first in factory, produce vertical pit shaft, the horizontal connecting cylinder that weld size does not wait on vertical pit shaft selects installation to get final product according to the real size of on-the-spot blowdown, drainage pipe more then.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the integrated manhole of large-bore plastics pipeline of the present utility model has following beneficial effect:
One, real size and angle according to job site blowdown, drainage pipe, vertically pit shaft can mate weld size and the different horizontal connecting cylinder of angle, it is extremely simple to construct, construction cost is lower, and because manhole and draining, blow-off line are all plastic pipe, its junction leakproof, application life is longer, can reach 50 years;
Two, vertically the outer wall of pit shaft and horizontal connecting cylinder is formed with the scroll ribs or forms level and smooth real wall, makes that the structure of manhole is more firm, and load performance is better;
Three, vertically pit shaft and horizontal connecting cylinder are high density polyethylene pipe, have good heat resistance and cold resistance, and chemical stability is good, also has higher rigidity and toughness, and mechanical strength is good, and dielectric properties, environmental stress crack resistance are also better;
Four, in the birdsmouth of horizontal connecting cylinder, be provided with electric fuse, when being connected, only needing to insert power supply and can finish welding with pipeline, can realize zero seepage.
