Preferably, gaps are formed between the second straight pipe section and the inner wall of the main pipe, and the distance between the gaps is 4-8 mm. The distance between the gaps is the distance between the outer wall of the straight pipe section II and the inner wall of the main pipe, the main pipe is communicated with the drainage pipelines on the upper floor and the lower floor, the straight pipe section II extends into the bellmouth I, and the bellmouth I is connected with the drainage pipelines in a socket and spigot manner so as not to be influenced.
Preferably, the first socket and the second socket are both provided with chamfers. The chamfer has a guiding effect, and the three-way pipe is conveniently connected with the drainage pipeline in a socket joint mode.
Preferably, the bottoms of the first socket and the second socket are provided with steps. The inner diameter of the channel of the main pipe is slightly smaller than the nominal inner diameter of the first bellmouth, the connecting part of the first bellmouth and the main pipe, namely the bottom of the first bellmouth, can form the step.
Preferably, the main pipe and the branch pipe are integrally formed members. The integrated component ensures the connection strength of the main pipe and the branch pipe, and is convenient for production and processing.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. the bent pipe section and the straight pipe section II are added on the branch pipe, so that the possibility that drainage of the main pipe flows backwards at the branch pipe can be prevented, and the problems of moisture regain and odor development of a toilet are effectively avoided;
2. the arc-shaped outer wall of the bent pipe section can effectively reduce the probability of wall-hanging retention of dirt in the main pipe and reduce the negative influence of drainage of the main pipe on the structural strength of the bent pipe section;
3. the utility model discloses a three-way pipe can be on the main drainage pipe of upper and lower floor the less secondary drainage pipe of switching diameter, has good practicality in the application of caisson secondary drainage.
