Reinforced type plastic inspection well
The invention discloses a reinforced type plastic inspection well, and relates to the field of inspection wells. The reinforced type plastic inspection well comprises a well base, a well shaft and a close-up walling crib, wherein the well shaft is connected at the upper end of the well base; and the close-up walling crib is connected at the upper end of the well shaft. The reinforced type plastic inspection well is characterized in that reinforcing ribsare arranged on the close-up walling crib; ring-shaped reinforcing rings are arranged on the walls of the well shaft and the well base; the well shaft adopts a hollow-wall PVC (polyvinyl chloride) pipe, an HDPE (high-density polyethylene) double-wall corrugated pipe, an HDPE winding pipe oran adjustable well shaft; the well base is formed by once injection-molding, pouring or rotational molding; andpipe-diameter variable and angle variable connection of the wall shaft and the wall base is realizedby virtue of parts such as a reducing joint, a sealing ring and the like. According to the reinforced type plastic inspection well, the ring stiffness and the bearing strength of the close-up well ring are increased, so that the service life of the inspection well is prolonged.
