Abstract

The invention provides a plastic inspection well, and relates to the field of inspection wells. The plastic inspection well comprises a well seat, a wellbore and a well ring with a shrink mouth, the upper end of the well seat is connected with the wellbore, and the upper end of the wellbore is connected with the well ring with the shrink mouth. The plastic inspection well is characterized in that reinforcing ribs are arranged on the well ring with the shrink mouth, annular reinforcing rings are arranged on the wellbore and the well seat wall respectively, a hollow-wall PVC pipe or an HDPE double-wall corrugated pipe or an HDPE winding pipe or an adjustable wellbore is adopted as the wellbore, the well seat adopts one-time injection molding or pouring molding or rotational molding, and pipe diameter changing and angle connecting are achieved through accessories such as a reducing joint and a seal ring. According to the plastic inspection well, the ring stiffness and the bearing strength of the well ring with the shrink mouth are improved, and the service life of the inspection well is prolonged.

Description

A kind of plastic inspection well

Technical field

The present invention relates to inspection shaft field, be specifically related to a kind of plastic inspection well.

Background technology

Inspection shaft is for rain sewage vent line and for maintainer people inspection, the attached construction of removing foreign body, is easy for making regular check on and dredging pipeline, prevents the necessary facility of line clogging.Inspection shaft is in use, pavement loading can act on around well by well lid, walling crib, well seat, the intensity of these parts each to inspection shaft has certain requirement, in each parts of existing inspection shaft, what intensity was relatively weak is closing in walling crib, want to extend the service life of inspection shaft, in addition it is also necessary to increase the intensity of closing in walling crib.

Summary of the invention

The present invention is to solve the problem existing for background technology, it is provided that a kind of plastic inspection well.

Technical scheme 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 characterised in that be provided with reinforcement in described closing in walling crib.

Annular stiffening ring it is both provided with on described pit shaft, well seat wall.

Described pit shaft uses hollow wall PVC, HDPE double-wall corrugated pipe, HDPE winding pipe and scalable pit shaft.

Described well seat uses once injection moulding, pours molding or rotation molding, reaches to change caliber and the connection of angle with the accessory such as reducing joint and sealing ring.

The invention has the beneficial effects as follows ring stiffness and the bearing strength increasing closing in walling crib, extend the service life of inspection shaft.

Accompanying drawing illustrates:

Fig. 1 is the structural representation of the present invention.

Detailed description of the invention

With reference to Fig. 1, a kind of plastic inspection well, include well seat 4, pit shaft 2, closing in walling crib 1, well seat upper end connects pit shaft 2, and pit shaft upper end connects closing in walling crib 1, it is characterised in that be provided with reinforcement 3 in described closing in walling crib 1.

Annular stiffening ring 5 it is both provided with on described pit shaft, well seat wall.

Described pit shaft 2 uses hollow wall PVC, HDPE double-wall corrugated pipe, HDPE winding pipe and scalable pit shaft.

Described well seat 4 uses once injection moulding, pours molding or rotation molding, reaches to change caliber and the connection of angle with the accessory such as reducing joint and sealing ring.
