Abstract

The utility model discloses a prefabricated plastics drainage switching well of integration, include: a well cover; the well body is formed by concentrically injecting a shaft and a well seat; the upper end of the well seat is provided with a conical hopper, and the lower end of the conical hopper is provided with an elbow connected with the service outlet pipe; the bottom of the shaft is connected with the upper end of the conical hopper. This application changes traditional chute form at switching well seat bottom trompil, discharges sewage from the bottom, thoroughly solves well casing siltation, blocks up the problem to and avoided the sewage refluence that the upper and lower stream arouses because the elevation problem. Meanwhile, in combination with the actual construction site conditions, because the discharge pipes are connected out from the lower part of the well seat, the shaft part can be connected into a plurality of indoor discharge pipes in multiple directions.

Description

Integrated prefabricated plastic drainage switching well

Technical Field

The utility model belongs to building and district sewage engineering field, more specifically say, be a prefabricated plastic drainage switching well of integration that is used for district to bury the indoor sewage discharge pipe of underground sewage system initiating terminal building and outdoor buried sewage system and is connected.

Background

In the sewage engineering of buildings and residential areas, the vertical building pipes are required to be combed sometimes, and the sewage outlet pipes of the buildings are turned over or newly built from the outer walls of the buildings. Because the outlet pipe of the original building is a PVC pipe, according to the experience of the previous engineering, if the indoor sewage discharge pipe and the outdoor buried sewage pipe are directly connected by adopting modes such as hoops, the joint is uneven, tools are often clamped at the joint when the indoor sewage discharge pipe and the outdoor buried sewage pipe are cleared, and inconvenience is brought to daily maintenance work. At present, a straight cylinder type plastic inspection well is arranged between an indoor sewage discharge pipe and an outdoor buried sewage pipe, and during specific implementation, the method occupies small space and cannot meet the requirement of connecting pipes of a plurality of household pipes; and the inspection well adopts a trough form, so that the problems of residue deposition, unsmooth drainage and slope falling exist.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a prefabricated plastics drainage switching well of integration, the problem that the takeover that adopts the plastics inspection shaft to lead to can't satisfy many service pipes among its aim at overcome prior art requires and the drainage is not smooth, the adverse slope.

In order to achieve the technical purpose, the following technical scheme is adopted in the application:

prefabricated plastics drainage switching well of integration includes: a well cover; the well body is formed by concentrically injecting a shaft and a well seat; the upper end of the well seat is provided with a conical hopper, and the lower end of the conical hopper is provided with an elbow connected with the service outlet pipe; the bottom of the shaft is connected with the upper end of the conical hopper.

Preferably, the side wall of the shaft is provided with a plurality of discharge pipe joints.

Preferably, the elbow is a 90 ° constant diameter elbow.

Preferably, the well lid is provided with a handle.

Preferably, the well body is injection molded from PP.

Owing to adopt above-mentioned technical scheme, this application changes traditional chute form at switching well seat bottom trompil, discharges sewage from the bottom, thoroughly solves well casing siltation, jam problem to and avoided the sewage refluence that the upper and lower stream arouses because the elevation problem. Meanwhile, in combination with the actual construction site conditions, because the discharge pipes are connected out from the lower part of the well seat, the shaft part can be connected into a plurality of indoor discharge pipes in multiple directions.

FIG. 1 is a cross-sectional view of an embodiment of the present application;

fig. 2 is a perspective view of the embodiment of fig. 1.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Referring to fig. 1 and 2, the integrated prefabricated plastic drainage transit well mainly comprises a well cover 1 and a well body consisting of a well shaft 2 and a well base 3.

In this embodiment, well lid 1 adopts phi 320's prefabricated plastics well lid, and is 80mm thick. The manhole cover 1 is provided with a handle 11.

Referring to fig. 1, the well body is formed by one-time concentric injection molding of a PP raw material. The shaft 2 and the well seat 3 are concentric reducing structures, the shaft 2 is large, the well seat is small, and the shaft can be perforated and connected in multiple directions. The outer diameter of the shaft 2 is phi 315, and the inner diameter is phi 295; the outer diameter of the well seat 3 is phi 200, a conical hopper 4 and a 90-degree elbow 5 are arranged in the well seat, and the total length of the shaft 2 and the well seat 3 is 530 mm; the diameter of the upper circle of the conical hopper 4 is the inner diameter of the shaft 2, and the diameter of the lower circle is the inner diameter of the service pipe 7; the 90-degree elbow 5 is an equal-diameter elbow, and the diameter of the 90-degree elbow is the inner diameter of the service outlet pipe 7; the house outlet pipe 7 is an outdoor buried sewage pipe of the building, and the outer diameter is phi 160. The well seat adopts a cone bucket type, sewage is connected in from a well shaft and is connected out from the well bottom through the cone bucket and an elbow.

When the method is implemented on site, the shaft 2 is perforated and connected on site according to the actual pipe diameter and elevation of the indoor sewage discharge pipe 6 of the building. When multiple sewage discharge pipes 6 are laid adjacent to or around the transfer well, multiple openings can be made in the shaft 2. The outlet pipe 7 is connected with the newly-built pipe section of the outdoor outlet pipe of the building in a socket-and-spigot manner, wherein the newly-built outdoor buried sewage pipeline adopts a dn160 standard pipe. Sewage in the building enters the novel switching well through the discharge pipe 6, then enters the newly-built dn160 standard pipeline through the conical hopper 4 and the 90-degree elbow 5, and finally is connected into the newly-built dn160 standard pipeline through the household outlet pipe 7, so that good connection between the indoor sewage discharge pipe of the building and outdoor buried sewage is achieved.

The utility model discloses at switching well seat bottom trompil, change traditional chute form, discharge sewage from the bottom, thoroughly solve the well casing siltation, block up the problem to and avoided the sewage refluence that the upper and lower stream arouses because the elevation problem. Meanwhile, in combination with the actual construction site conditions, because the discharge pipes are connected out from the lower part of the well seat, the shaft part can be connected into a plurality of indoor discharge pipes in multiple directions. The one-time injection molding structure has good tightness, can be produced in a factory in a large scale, and has the advantages of wide applicable area, flexible and efficient construction, convenient construction process, small occupied area, convenient maintenance and management and the like.

The above-described embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Those skilled in the art will recognize that changes and modifications can be made in the invention as described herein without departing from the scope of the invention as defined by the appended claims.
