Abstract
Provided is a plastic inspection well, pertaining to the field of inspection wells. The plastic inspection well comprises a well seat, a wellbore and a necking well loop. The upper end of the well seat is connected with the wellbore. The upper end of the wellbore is connected with the necking well loop. The plastic inspection well is characterized in that reinforcing ribs are arranged on the necking well loop; annular reinforcing rings are arranged on the wellbore and the wall of the well seat; a hollow-wall PVC pipe, an HDPE double-wall corrugated pipe, an HDPE winding pipe and an adjustable wellbore are adopted by the wellbore; the well seat is formed by one-step injection, pouring molding or rotational molding; and a reducing joint, a sealing ring and other accessories are utilized for changing pipe diameters and making angle connection. The plastic inspection well helps to enhance ring stiffness and bearing strength of the necking well loop and prolong service lifetime of the inspection well.
Description
Technical field
The present invention relates to manhole field, be specifically related to a kind of plastic inspection well.
Background technology
Manhole is the attached construction checking, remove foreign matter for rain sewage vent line and for maintainer people, is be convenient to make regular check on and dredging pipeline, prevents the necessary facility of line clogging.Manhole in use, pavement loading can act on around well by well lid, walling crib, well seat, this has certain requirement to the intensity of each parts of manhole, in each parts of existing manhole, what intensity was relatively weak is closing in walling crib, want the application life extending manhole, also need the intensity increasing closing in walling crib.
Summary of the invention
The present invention, in order to solve the problem existing for background technology, provides a kind of plastic inspection well.
Technical scheme of the present invention is as follows:
A kind of plastic inspection well, includes well seat, pit shaft, closing in walling crib, and well seat upper end connects pit shaft, and pit shaft upper end connects closing in walling crib, it is characterized in that described closing in walling crib is provided with reinforcing rib.
Described pit shaft, well seat wall are all provided with annular stiffening ring.
Described pit shaft adopts hollow wall PVC, HDPE double-wall corrugated pipe, HDPE wind pipe and adjustable pit shaft.
Described well seat adopts once injection moulding, builds shaping or rotation molding, reaches the connection changing caliber and angle with the accessory such as reducing joint and sealing ring.
The invention has the beneficial effects as follows the ring stiffness and bearing strength that increase closing in walling crib, extend the application life of manhole.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
With reference to Fig. 1, a kind of plastic inspection well, includes well seat 4, pit shaft 2, closing in walling crib 1, and well seat upper end connects pit shaft 2, and pit shaft upper end connects closing in walling crib 1, it is characterized in that described closing in walling crib 1 is provided with reinforcing rib 3.
Described pit shaft, well seat wall are all provided with annular stiffening ring 5.
Described pit shaft 2 adopts hollow wall PVC, HDPE double-wall corrugated pipe, HDPE wind pipe and adjustable pit shaft.
Described well seat 4 adopts once injection moulding, builds shaping or rotation molding, reaches the connection changing caliber and angle with the accessory such as reducing joint and sealing ring.
The invention has the beneficial effects as follows the ring stiffness and bearing strength that increase closing in walling crib, extend the application life of manhole.
