Multi-pipe confluence inspection well with butt joint pipe top

Abstract

The invention relates to a multitube convergence inspection well with tube tops in flush joint. The multitube convergence inspection well comprises a well shaft, a well base, and a bell mouth which is arranged on the well base and connected with a main pipeline, wherein a well lid base and a well lid are arranged on the well shaft; at least two interfaces connected with branch pipelines are further arranged on the well base in parallel; each interface comprises a pipeline bell mouth integrated with the main pipeline; pipe joints of two or three pipe diameters in a small hole, a medium hole and a big hole are coaxially arranged on the well base; and central lines of the pipe joints are arranged above the central line of the well base. The multitube convergence inspection well disclosed by the invention is novel in conception, the pipe joints of the most three common specifications are coaxially arranged and can be machined on site according to actual needs in a construction site, the operation is simple and convenient, and the multitube convergence inspection well in such a structure is more beneficial to large-batch manufacture, so that the production cost is lowered and the production cycle is reduced; and the upper edge of the pipe joint with the maximal pipe diameter is parallel and level to the upper edge of the well base, so that falling is formed due to water level rise during pollution or water discharge, and thus, the flow rate of discharged pollution or water is increased and the problem of downstream backward flowing is solved.

Description

technical field [0001] The invention relates to the technical field of pipelines and inspection wells, in particular to a multi-pipe confluence inspection well with butt joint pipe tops. Background technique [0002] With the advancement of urbanization, the requirements for the reasonable laying of pipe networks for urban water supply and drainage and other fluid transportation are getting higher and higher. The plastic inspection well is made of high polymer resin as the raw material for one-time injection molding, and it is assembled in separate parts. It is easy to use and convenient for future repair and maintenance. It has become an indispensable unit for the construction of urban water supply and drainage pipe networks. In particular, the laying of urban rain and sewage drainage pipe network is more difficult, and a little unreasonable will bring many troubles to daily life in the future. A well-structured inspection well can bring a lot of convenience to daily life,...

Problems solved by technology

However, the diameters of the actual pipes used are different, and it is difficult to manufacture and process various pipes after statistics in advance. The manufacturing cycle is greatly prolonged, which is not conducive to mass production of products, and the cost is high.

It even appears that each inspection well is a non-standard part, and each needs to redesign the mold and reprocess, which is difficult, reduces efficiency, and keeps high costs
