Abstract
The invention provides an environmentally friendly plastic inspection well, and relates to the field of inspection wells. The environmentally friendly plastic inspection well comprises a well seat, a well cylinder and an opening contraction well ring. The upper end of the well seat is connected with the well cylinder. The upper end of the well cylinder is connected with the opening contraction well ring. The environmentally friendly plastic inspection well is characterized in that reinforcing ribs are arranged on the opening contraction well ring, both the well cylinder and the wall of the well seat are provided with annular reinforcing rings, a hollow-wall PVC pipe, an HDPE double-wall corrugated pipe, an HDPE winding pipe and an adjustable well cylinder body are adopted for the well cylinder, the well seat is formed through one-time injection molding or pouring molding or rotational molding, and pipe diameter changing and angle connection are achieved through reducing joints, sealing rings and other accessories. According to the environmentally friendly plastic inspection well, the ring stiffness and the bearing strength of the opening contraction well ring are improved, and the service life of the inspection well is prolonged.
Description
Technical field
The present invention relates to manhole field, be specifically related to a kind of environment-friendly type plastic manhole.
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 environment-friendly type plastic manhole.
Technical scheme of the present invention is as follows:
A kind of environment-friendly type plastic manhole, 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 environment-friendly type plastic manhole, 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.
