Abstract
Integral molded plastic manhole well seat, comprise manhole well seat, the perpendicular bellmouth of connecting well seat and horizontal bellmouth, it is characterized in that the above extremely perpendicular bellmouth oral area appearance of described horizontal bellmouth appearance and horizontal bellmouth central plane arranges pawl shape reinforcing ring, perpendicular bellmouth outer bottom arranges continuous circular shape and strengthens frustum, and perpendicular bellmouth inner bottom part arranges continuous circular shape supporting step.This programme arranges after pawl shape reinforcing ring to erecting bellmouth oral area appearance in horizontal bellmouth appearance and more than horizontal bellmouth central plane, has greatly increased the intensity of horizontal bellmouth, perpendicular bellmouth and well seat, increases the service life.The width of step should match with the size that requires of well seat socket wall thickness and bell and spigot rubber seal rings for seal, is beneficial to pit shaft, imports pipe and effuser sealing grafting.
Description
Technical field
The utility model relates to a kind of high-intensity integral molded plastic manhole well seat, is mainly used in one residential, municipal draining, blowdown.
Background technology
Plastic inspection well seat is divided into chute well and catch-basin, and design point is respectively divided into again initial well, straight-through well, 90 degree elbow wells, left three driftings, right three driftings, four-way well etc. according to tube connector for chute well and catch-basin.In former plastic inspection well seat, owing to being subject to the restriction of molding (injection mold) technology and cost of investment, between the pit shaft of some manhole well seats and tube connector, adopt edge to spell structure, inlay spelling place intensity difference and easily produce mass defect, and adopt rotational molding technique production efficiency low especially, because appearance the whole body is smooth without reinforcing rib, product strength is poor.The connection pit shaft bellmouth bottom of well seat and remittance pipe, the same tapering that is all designed in effuser bellmouth bottom, like this, the bellmouth bottom that connects pit shaft is subject to the vertical of pit shaft and produces cross component force, causes the connection pit shaft bellmouth bottom of well seat easily to be broken, and application life is low.When well seat is installed, affected by the impact force that imports pipe, effuser insertion, well seat easily moves built on the sand.In well seat, the position that crosses of pit shaft interface and pipe joint, without arc transition, is unfavorable for maintenance and the maintenance of pipeline.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, and a kind of good integral strength is provided, long product lifecycle, and production efficiency is high, is beneficial to the integral molded plastic manhole well seat of the installation of well seat and pipeline maintenance, maintenance.
The technical scheme of the utility model integral molded plastic manhole well seat is: comprise manhole well seat, the perpendicular bellmouth of connecting well seat and horizontal bellmouth, it is characterized in that the above extremely perpendicular bellmouth oral area appearance of described horizontal bellmouth appearance and horizontal bellmouth central plane arranges pawl shape reinforcing ring, perpendicular bellmouth outer bottom arranges continuous circular shape and strengthens frustum, and perpendicular bellmouth inner bottom part arranges continuous circular shape supporting step.
Integral molded plastic manhole well seat of the present utility model, described horizontal bellmouth appearance and horizontal bellmouth central plane are above arranges pawl shape reinforcing ring to erecting bellmouth oral area appearance, has greatly increased the intensity of horizontal bellmouth, perpendicular bellmouth and well seat, increases the service life; Perpendicular bellmouth outer bottom arranges continuous circular shape and strengthens frustum, has improved well seat axial load performance; Perpendicular bellmouth inner bottom part arranges continuous circular shape supporting step, and the width of step should match with the size that requires of well seat socket wall thickness and bell and spigot rubber seal rings for seal, is beneficial to pit shaft, remittance pipe and effuser sealing and pegs graft.
Integral molded plastic manhole well seat of the present utility model, described perpendicular bellmouth and the inwall bead of horizontal bellmouth arrange chamfering, and pit shaft, remittance pipe and effuser easily insert, easy for installation.Described well seat bottom arranges annular brace, ensures base plane degree, improves well seat stability, and annular brace is provided with several caulking grooves, and caulking groove can be settled round bar, is beneficial to when well seat is installed and is difficult for moving.In the middle of described well seat bottom, netted reinforcing rib is set, improves well seat bottom strength.Described well seat inwall arranges current deflecting curve, reduces resistance to water-flow, and current are more unobstructed.Between described perpendicular bellmouth and horizontal bellmouth, have transition arc, the radius r >=10mm of described transition arc, ensures that clear and coherent instrument discrepancy is smooth and easy, avoids current loss, reduces the probability of line clogging.
