Abstract
The utility model discloses a two-way plastic inspection well, which comprises a well bore, a pipeline connector and an inspection hole, wherein the pipeline connector, the inspection hole and the well bore are formed through one-time injection molding by adopting HDPE (high-density polyethylene); a bell end structure matched with a pipeline socket is arranged inside the inspection hole; an extending internal orifice that can be embedded in a pipeline is arranged inside the pipeline connector; and the internal diameter of the inspection hole is greater than the external diameter of the pipeline connector. The two-way plastic inspection well is formed through one-time injection molding by adopting the HDPE, so that the sealing performance is excellent, the bell end structure is arranged inside the inspection hole and the extending internal orifice is arranged inside the pipeline connector, so that the two-way plastic inspection well is convenient to construct and install, and the pipeline connector is also compact, and no leakage at the pipeline connector can be ensured.
Description
Technical field
The utility model belongs to row's feedwater piping field, relates to a kind of manhole, is specifically related to a kind of two-way plastic inspection well.
Background technology
Manhole in the underground piping system claims again piping shaft or inspection shaft, and it is to look into, remove the ancillary structure of foreign matter for the rain sewage vent line and for the maintainer manual inspection, is to be convenient to make regular check on and dredging pipeline, prevents the necessary facility of line clogging.
At present, Large Underground pipeline such as sewer, sewage vent line, cable are laid the manhole of pipeline etc., especially for the inspection shaft in the drainage pipeline, major part is that the underground in pipe path has been built a well body to ground with brick or cement, then cover a well lid thereon, have perforate at the well body side surface and be used for the pipeline connection.There are problems in this inspection shaft, such as long construction period, produce easily weeds, the dredging the not easy current that make not smooth, cause secondary pollution of surrounding environment etc.
The manhole of plastic material can overcome the problem that above-mentioned manhole exists.Expansion along with the manhole scope of application, the accessory manufacturer of manhole and manhole is numerous now, the mode of manufacturing plastic inspection well is also more and more, wherein use more widely mode be that Bian between pit shaft and the well body is connected with welding manner, this welding manner causes the poor sealing performance of manhole easily, the shortcomings such as joint is compact not are so need to be improved.Simultaneously, because that manhole needs when using is buried underground, its inplane pressure is larger, and it is also particularly important that manhole bears the ability of inside and outside pressure.
Summary of the invention
Technical problem to be solved in the utility model provides the good two-way plastic inspection well of a kind of pipe seal performance.
For solving the problems of the technologies described above, a kind of two-way plastic inspection well of the utility model, comprise well bore, with described well bore Bian pipe joint and the inspection hole with the HDPE single injection-molded, be provided with the bellmouth structure that is complementary with the pipeline socket in the described inspection hole, be provided with the extension internal orifice that can embed pipeline in the described pipe joint, the internal diameter of described inspection hole is greater than the external diameter of described pipe joint.
Compared with prior art, the beneficial effect that the utlity model has is: the utility model Bian HDPE single injection-molded, favorable sealing property, be provided with in the inspection hole and be provided with the extension internal orifice in bellmouth structure and the pipe joint, construction install convenience not only, and pipe joint is compact, can guarantee pipe joint place leakproof.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of two-way plastic inspection well of the utility model.
The specific embodiment
As shown in Figure 1, a kind of two-way plastic inspection well, comprise well bore 1, with described well bore 1 Bian pipe joint 2 and the inspection hole 3 with the HDPE single injection-molded, be provided with the bellmouth structure that is complementary with the pipeline socket in the described inspection hole 3, be provided with the extension internal orifice 4 that can embed pipeline in the described pipe joint 2, the internal diameter of described inspection hole 3 is greater than the external diameter of described pipe joint 2.The utility model Bian HDPE single injection-molded, favorable sealing property is provided with in the inspection hole and is provided with the extension internal orifice in bellmouth structure and the pipe joint, and not only construction install convenience, and pipe joint is compact, can guarantee pipe joint place leakproof.
