Plastic inspection well
The invention provides a plastic inspection well, and relates to the field of inspection wells. The plastic inspection well comprises a well seat, a shaft and a closing-in well ring, wherein the upper end of the well seat is connected with the shaft; and the upper end of the shaft is connected with the closing-in well ring. The plastic inspection well is characterized in that reinforcing ribs are arranged on the closing-in well ring; annular reinforcing rings are respectively arranged on the shaft and the wall of the well seat; the shaft consists of a hollow-wall PVC (polyvinyl chloride) tube, an HDPE (high-density polyethylene) double-wall corrugated tube and an HDPE winding tube and is adjustable; the well seat is subjected to one-step injection molding, pouring molding or rotational molding; and tube diameters and angles can be changed through accessories such as a reducing joint and a sealing ring. The ring stiffness and the pressure bearing strength of the closing-in well ring are improved, and the service life of the inspection well is prolonged.
