Rainwater and sewage diversion sleeve for buildings

Abstract

The invention belongs to the technical field of building construction, and particularly relates to a rainwater and sewage diversion sleeve for buildings. The rainwater and sewage diversion sleeve comprises a rainwater pipe and a sewage discharge pipe, the rainwater pipe is formed by fixedly sleeving a plurality of outer pipelines, outer tee joints and outer elbows, and the sewage discharge pipe is formed by fixedly sleeving a plurality of inner pipelines, inner tee joints and inner elbows. Supporting frames sleeve the outer sides of the inner pipelines at equal intervals in sequence, the outer tee joints and the inner tee joints are provided with outer connecting openings and inner connecting openings which fixedly sleeve connectors separately, the connectors comprise inner connectors and outer sealing plates, and rainwater pipe sealing heads fixedly sleeve the bottom end of the rainwater pipe and the bottom end of the sewage discharge pipe. The rainwater pipe is arranged on the outer side of the sewage discharge pipe to distribute rainwater and sewage, discharge of solid waste in the sewage discharge pipe is prevented from being affected, better practical value is achieved, the rainwater pipe and the sewage discharge pipe are convenient to install, stable in connection and low in cost, and the supporting frames play a role in absorbing water flow potential energy while playing a supporting role; and the sewage discharge pipe is prevented from shaking, impacting and being damaged in the rainwater pipe.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a rain and sewage diversion sleeve for buildings. Background technique [0002] Rain and sewage diversion is a drainage system, which refers to the separation of rainwater and sewage, each of which is transported by a pipeline for discharge or subsequent treatment. The rainwater is directly discharged to the river through the rainwater pipe network, and the sewage is collected through the sewage pipe network. , sent to the sewage treatment plant for treatment, to avoid sewage directly entering the river to cause pollution, and the collection and utilization of rainwater and centralized management and discharge can reduce the impact of water volume on the sewage treatment plant and ensure the treatment efficiency of the sewage treatment plant. [0003] Rainwater in existing buildings is collected by separate pipelines, and domestic sewage (washing machine sewage, kit...

AI Technical Summary

Problems solved by technology

[0003] Rainwater in existing buildings is collected by separate pipelines, and domestic sewage (washing machine sewage, kitchen sewage, etc.) is also collected by separate pipelines, which causes waste of pipeline resources to a certain extent and reduces construction efficiency. Patent No. The invention patent document of CN 108396844 A discloses a rain and sewage diversion sleeve for buildings, which includes an outer tube and an inner tube that are not connected to each other, and the inner tube is arranged in the outer tube and connected to the outer tube through a connecting piece; Among them, the inner pipe is used to collect rainwater, the upper end is provided with a rainwater collection port, and the tail end is provided with a rainwater discharge port; the outer pipe is used to collect sewage, the upper end is sealed with the inner pipe, and the tail end is provided with a sewage discharge port. Sewage collection inlet, put the rainwater pipeline into the domestic sewage pipeline, save the space occupied by the pipeline, and reduce the installation and construction process; During use, the connecting piece will seriously hinder the solid waste in the sewage collected and discharged in the outer pipe, such as feces, food residue, etc., which will easily cause the blockage of the pipeline. , The inner pipe plays the role of connection and fixation and has not been explained, so it has no actual use value
