Abstract

The utility model discloses an assembled plastic inspection well, comprising a well head, a well shaft and a base that are mutually independent, wherein both the lower end of the well head and the upper end of the base are provided with connecting sockets; the well shaft is a dual-wall corrugated pipe or a dual-flat-wall enwinding pipe; two ends of the well shaft can be welded with the well head and the base respectively by the connecting socket; both the dual-wall corrugated pipe and the dual-flat-wall enwinding pipe are existing general resources; and the well head and the base can be sent to all places conveniently for the existing resources integration according to the standardized production so that the manufacturing cost is greatly reduced. Because all parts of the assembled plastic inspection well are mutually independent, production dies have simpler structures, lower corresponding manufacturing cost, shorter production period of the product and higher efficiency compared with wholly formed dies; when in use, the length of the well shaft can be customized according to practical assembly requirement; the well shaft can be welded in the field and can be used more flexibly; during the piling and conveying process, because all parts have more regular shapes compared with the parts of the integrated inspection well, the parts can be piled in good order and occupy less space; furthermore, the piling quantity can be effectively increased, and the conveying cost can be reduced.

Description

The combined plastic manhole

Technical field

The utility model relates to a kind of connection well that is used to connect the underground water supply and drainage pipeline, particularly a kind of combined plastic manhole.

Background technology

Manhole is commonly called as " inspection shaft ", generally is located on water supply and sewerage pipeline intersection, turning, caliber or gradient change place, drop place and the straight line pipeline section to locate at a certain distance, be convenient to make regular check on, the plumbing ancillary structure of cleaning and dredging pipeline.

Existing plastic inspection well product category is various, but most of all becomes whole by one-shot forming when producing, and all-in-one-piece manhole exists that following some is not enough: 1. mould structure complexity, manufacturing cost height; 2. irregular owing to the manhole shape of product, and volume is bigger, and the warehousing stacking takes up room also bigger, is unfavorable for large-scale production, simultaneously, has also increased cost of transportation and transport difficulty; 3. the pit shaft height is just definite formed product the time, can't adjust according to the needs of actual installation; 4. can not integrate existing double-wall corrugated pipe and two flat walls wind pipe on the spot as pit shaft, take big quantity space during transportation, greatly increase cost of transportation.

At above-mentioned deficiency, need existing manhole is improved, make it overcome above-mentioned shortcoming, reduce and produce and cost of transportation, simultaneously, be convenient to according to the suitable specification of actual installation needs customization.

The utility model content

In view of this, the utility model provides a kind of combined plastic manhole, its objective is: reduce the production and the cost of transportation of manhole, and its height dimension can be adjusted flexibly according to the actual installation needs.

Combined plastic manhole of the present utility model, comprise separate well head, pit shaft and base, described well head lower end be provided for pit shaft upper end seal welding be connected bellmouth I, described base upper end be provided for pit shaft lower end seal welding be connected bellmouth II, described pit shaft is double-wall corrugated pipe or two flat walls wind pipe.

Further, described pit shaft two ends are withstood respectively and are connected bellmouth I and be connected bellmouth II formation bevel for welding.

The beneficial effect of utility model: combined plastic manhole of the present utility model, comprise separate well head, pit shaft and base, described well head lower end be provided for pit shaft upper end seal welding be connected bellmouth I, described base upper end be provided for pit shaft lower end seal welding be connected bellmouth II, described pit shaft is double-wall corrugated pipe or two flat walls wind pipe, the pit shaft two ends can be welded with well head and base respectively by connecting bellmouth, double-wall corrugated pipe and two flat walls wind pipe all are existing general resources, well head and base are convenient to mail to various places by standardized production and are integrated the existing resources, and manufacturing cost is reduced greatly.Because each several part is separate, its production mould is simpler with respect to the integrally forming mould structure, and manufacturing cost is also corresponding lower, and life cycle of the product is shorter, and efficient is higher; During use, can be according to actual installation needs customization pit shaft length, field Welding is used more flexible; When stacking and transportation, because the relative monolithic manhole of each parts, shape is more regular, is easy to orderly stacking, and it is little to take up room, and can effectively increase the stacking amount and reduce cost of transportation.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 adopts the structural representation of double-wall corrugated pipe for the utility model pit shaft;

Fig. 2 is the structural representation of two flat walls wind pipe.

The specific embodiment

Fig. 1 adopts the structural representation of double-wall corrugated pipe for the utility model pit shaft, Fig. 2 is the structural representation of two flat walls wind pipe, as shown in the figure: the combined plastic manhole of present embodiment, comprise separate well head 1, pit shaft 2 and base 3, described well head 1 lower end be provided for pit shaft upper end seal welding be connected bellmouth I 4a, base 3 upper ends be provided for pit shaft lower end seal welding be connected bellmouth II4b, described pit shaft 2 is double-wall corrugated pipe or two flat walls wind pipe, double-wall corrugated pipe and two flat walls wind pipe all are existing general resources, can be in the buying nearby of construction ground, well head and base are convenient to mail to various places by modular size production and are integrated the existing resources, cost is reduced greatly, during use, directly adopt ready-made double-wall corrugated pipe blanking, not only the efficient height also can customize pit shaft type and length according to the actual installation needs, field Welding, easy to use flexible; Certainly, adopt the pit shaft of two flat walls wind pipe or other types also can realize the purpose of this utility model.Because each several part is separate, its production mould is simpler with respect to the integrally forming mould structure, and manufacturing cost is also corresponding lower, and life cycle of the product is shorter, and efficient is higher; When stacking and transportation, because the relative monolithic manhole of each parts, shape is more regular, is easy to orderly stacking, and it is little to take up room, and can effectively increase the stacking amount and reduce cost of transportation.

In the present embodiment, described pit shaft 2 two ends are withstood respectively and are connected bellmouth I 4a and be connected bellmouth II 4b, and pit shaft 2 two ends form bevel for welding respectively with being connected between bellmouth I 4a, the connection bellmouth II 4b respectively, can effectively improve weld strength.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
