Abstract
The utility model relates to the technical field of urban construction, and particularly comprises a precast cement inspection well used for plastic pipeline connection. The inspection well comprises an inspection well body, wherein a connecting hole is formed in a shaft of the inspection well body, an edge of the connecting hole is provided with an embedded plastic intersection circle, an expansion adhesive tape is arranged between the inspection wheel and the embedded plastic intersection circle and the embedded plastic intersection circle is connected with an external connecting pipe through a plastic welding strip. According to the technical scheme provided by the utility model, a traditional plastic inspection well is changed into the concrete inspection well, therefore, the concrete inspection wheel is firmer and more durable in the process of installing and using; furthermore, the expansion adhesive tape is arranged between the inspection wheel and the embedded plastic intersection circle, therefore, the airtightness of a joint between the embedded plastic intersection circle and the concrete inspection wheel can be effectively guaranteed, and the leakage phenomenon of the joint can be prevented; in addition, a joint between the embedded plastic intersection circle and the connecting pipe is more convenient and quick to connect by the welding of the inside and outside plastic welding rods. The precast cement inspection well provided by the utility model has the characteristics of being simple in structure, convenient to install and firm and durable to use.
Description
Technical field
The utility model relates to urban construction facility technology field, is a kind of Prefabricated Concrete inspection shaft connecting for plastic pipe specifically.
Background technique
When plastic pipe is installed, certain distance need to arrange an inspection shaft, in pipeline using process for the inspection to pipeline, remove contamination etc.Although the plastic inspection well connecting due to existing plastic pipe is that same material connects with pipeline, quick, strick precaution seepage when pipeline connects with well are met, but because plastic inspection well belongs to plastic material, in construction and using process, be subject to the extruding of lateral earth pressure to cause well body deformability, the problem of breaking even.
Model utility content
The purpose of this utility model is the problem existing for above-mentioned technology, and a kind of Prefabricated Concrete inspection shaft connecting for plastic pipe is provided, and has feature sturdy and durable, easy to connect, good airproof performance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Prefabricated Concrete inspection shaft connecting for plastic pipe, comprise inspection shaft, described manhole shaft is provided with attachment hole, described attachment hole edge is provided with pre-buried plastics and passes through mutually circle, described inspection shaft and pre-buried plastics pass through mutually between circle and are provided with expansion adhesive tape, and described pre-buried plastics pass through mutually circle and are connected with external connecting tube by Plastic Welding bar.
Further, described pre-buried plastics pass through circle and inspection shaft joint is provided with plastics embedded part mutually.
Further, described Plastic Welding bar is welded on the interior outside that pre-buried plastics pass through circle and external connecting tube connecting sewing mutually.
Further, described pre-buried plastics pass through circle and external connecting tube all adopts the plastics of identical material to make mutually.
Useful technique effect of the present utility model is: in the technical solution of the utility model, change the inspection shaft of conventional plastic into concrete inspection shaft, more sturdy and durable in the time installing and using, concrete inspection shaft is provided with expansion adhesive tape with the joint that pre-buried plastics pass through circle mutually, effectively ensure that pre-buried plastics pass through the sealing of circle and concrete inspection shaft joint mutually, avoid joint water leakage phenomenon; In addition it is more convenient when, pre-buried plastics pass through mutually joint between circle and connecting tube and are connected by being welded on of interior outside Plastic Welding bar.The utlity model has simple in structure, easy for installation, robust feature.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of Prefabricated Concrete inspection shaft connecting for plastic pipe, comprise inspection shaft 1, inspection shaft 1 pit shaft is provided with attachment hole, attachment hole edge is provided with pre-buried plastics and passes through mutually circle 2, inspection shaft 1 and pre-buried plastics pass through mutually between circle 2 and are provided with expansion adhesive tape 5, and pre-buried plastics pass through mutually circle 2 and are connected with external connecting tube 3 by Plastic Welding bar 4.
Wherein, pre-buried plastics pass through mutually circle 2 and are provided with plastics embedded part 6 with inspection shaft 1 junction surface, and the effect of plastics embedded part 6 is mainly pre-buried plastics to be passed through to circle 2 mutually be well fixed on the attachment hole edge that detects well.
Wherein, Plastic Welding bar 4 is welded on the interior outside that pre-buried plastics pass through circle 2 and external connecting tube 3 connecting sewings mutually, utilize the welding of Plastic Welding bar can ensure the sealing of joint in the interior outside of connecting sewing, there is good resistance to pressure simultaneously, obviously also Plastic Welding bar 4 can be welded between connecting sewing, but welding difficulty is large, if poor sealing does not with great difficulty appear in welding, cause water leakage phenomenon.
Wherein, pre-buried plastics pass through mutually circle 2 and external connecting tube 3 all adopts the plastics of identical material to make, and adopt the material of identical material to make between the two, ensure there is identical expansion coefficient, prevent plastics embedded part 6 come off and seam crossing leak.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
