Through the technical scheme, the small end of the reducing pipe is smaller than the length of the short shaft of the cross section of the end part of the flat pipe, and the connecting part is in smooth transition, so that water flow can smoothly flow into the flat pipe from the reducing small end, large water flow impact cannot be generated on the joint position, and siltation of impurities in the water flow at the joint of the flat pipe is reduced.

Furthermore, a main pipe is arranged at a main pipe opening of the tee joint, and the length of the flat pipe is larger than the diameter of the main pipe.

Through above-mentioned technical scheme, flat tub of length is greater than and is responsible for the diameter, is in order that flat tub of can be in the person in charge below to support the person in charge of top, is responsible for and is connected with the tee bend person in charge mouth, and rivers flow from being responsible for, and the rivers that need intersect and the diversion then flow through bellows and flat tub of pipe.

The utility model has the advantages that:

1) Can make things convenient for pipeline intersection and rivers switching-over, reply the later stage do not have enough space to set up the pipeline that intersects, perhaps the pipeline bottom needs additionally pass the condition of pipeline. Flat pipe both ends are equipped with the reducing pipe, reducing pipe major possession and bellows threaded connection, reducing pipe minor possession is direct and flat tub of fixed connection, can make major diameter's bellows rivers flow in flat intraductal through reducing pipe major possession, make rivers widen, become the flat pipe by circular pipe, pass between two pipelines or pass from the pipeline bottom through the flat pipe, can reduce the distance between the pipeline greatly, the problem that the diversion is needed for a short time to the better reply distance between the pipeline

2) Can be freely stretched, and can bend the pipeline according to actual operation. The outer wall of the corrugated pipe is provided with a plurality of expansion joints, so that the corrugated pipe can be expanded and bent at a certain angle, and various complex pipeline conditions in actual work can be effectively responded.

3) Can realize the reposition of redundant personnel of trunk line and reduce the velocity of flow, be responsible for with the tee bend and be connected the mouth of pipe, rivers flow from being responsible for, are provided with the check valve between the tee bend branch pipe mouth and the bellows, need cross then through bellows and flat tub of outflow with the rivers of diversion, after rivers flowed into the bellows through the check valve from the tee bend branch pipe, rivers can not flow back to in the trunk, become the flat pipe by the circular pipe for rivers widen, the velocity of flow reduces.
