Detailed Description

To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the attached drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention, and obviously, the described embodiments are part of the embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

A drainage pipe structure for high-rise buildings, comprising:

the building comprises a building body 1, wherein the building body 1 sequentially comprises a top layer part 11, a middle layer part 12 and a bottom layer part 13 from top to bottom, a plurality of exhaust ports are formed in the top layer part 11 at intervals, pipeline lock catches 221 are formed in the outer end surface of the middle layer part 12 at intervals, and concrete buttress is arranged on the bottom layer part;

the drainage pipe mechanism comprises a double-vertical-pipe drainage system 21 arranged inside the top layer part 11, the double-vertical-pipe drainage system 21 is communicated with the outside through the exhaust port, the lower end of the double-vertical-pipe drainage system 21 is connected with a single-vertical-pipe drainage system 22 arranged outside the middle layer part 12, and the lower end of the single-vertical-pipe drainage system 22 is connected with a sewage system 23 buried in the concrete buttress. By dividing the drainage system into a high-rise, a middle-rise and a low-rise drainage pipe structure, selecting a double-riser drainage system 21 in the high-rise range of the house body 1, and switching to a single-riser drainage system 22 in the middle-rise part 12, the installation of the pipeline is simplified. Besides, a plurality of air exhaust ports are arranged on the top layer part 11 of the house body 1 at intervals, and the double-riser drainage system 21 is communicated with the outside through the air exhaust ports, so that indoor water return caused by blockage of a single air exhaust port is avoided. Simultaneously, because the sewage in the drain pipe can produce a large amount of peculiar smell gas or even combustible gas, if can not in time discharge, can appear gas and be leaded to the pipeline impaired by the ignition when meeting with the naked light, a plurality of gas vents can be faster exchange pipeline internal gas and outside air.

As a further improvement, the dual-riser drainage system 21 specifically includes a drainage riser 214 and a ventilation riser 211, the ventilation riser 211 and the drainage riser 214 are communicated with the ventilation riser 211 through a three-way cyclone, and one end of the ventilation riser 211, which is far away from the three-way cyclone, penetrates through the exhaust port and is communicated with the outside. Generally, the three-way cyclone in a building is made of a PVC material, however, when the floor is high, the vanes inside the three-way cyclone made of the PVC material are easily damaged by water pressure, and the damaged vanes are difficult to take out from the pipeline to cause blockage, so it is preferable that the three-way cyclone is made of a PE material.

As a further improvement, a trash holding groove 213 is further provided on the outer end surface of the top layer 11, one end of the ventilation vertical pipe 211 extending out of the exhaust port is fixedly connected with a right-angled bent pipe 212, and one end of the right-angled bent pipe 212 far away from the exhaust port faces into the trash holding groove 213.
