the end portion that the second pipeline is close to first pipeline is provided with the section of necking down, and the outer wall evenly distributed of the section of necking down has a plurality of recesses, sets up the caulking groove on the first pipeline inner wall, is provided with in the recess to insert to locate in order to with the fan-shaped scalable stopper of first pipeline and second pipe connection, and the end wall of scalable stopper in the recess is provided with limit stop, be provided with the elastic component that compresses tightly scalable fixture block to the caulking groove direction in the recess.
Through above-mentioned technical scheme, when installing first pipeline in the second pipeline, scalable fixture block on the second pipeline can contract to the recess in, aim at with the caulking groove until scalable stopper, scalable stopper can stretch out the recess and inlay card in the caulking groove this moment.
The invention is further configured to: the first water pipe inner wall is provided with annular L type boss, and one edge of L type boss just distributes to the second pipeline, and the second pipeline just is provided with the annular to the tip of first pipeline, is provided with the skeleton oil blanket in the annular, just the L type boss just inlays in the skeleton oil blanket to the border inlay card of second pipeline.
Through above-mentioned technical scheme, the setting of L type boss can give water and play the effect of water conservancy diversion, reduces the phenomenon that the seepage appears in the gap department of the connection of water flow through first pipeline and second pipeline.
The invention is further configured to: the edge of the L-shaped boss close to the framework oil seal comprises a trapezoidal section connected with the other edge and a rectangular section installed in the framework oil seal, and the large end of the trapezoidal section faces to the water flow direction.
Through above-mentioned technical scheme, trapezoidal section can play the effect of water conservancy diversion, and the incline direction of trapezoidal section is towards rivers direction, then can guide rivers direction and rectangle section to have the contained angle, then the phenomenon of leaking appears in the skeleton oil blanket department in rivers just being difficult for appearing.
In summary, compared with the prior art, the beneficial effects of the invention are as follows:
1. the sewage draining pipeline is convenient to operate during installation and has good sealing performance.

Detailed Description
The present invention will be described in further detail with reference to examples.
A connecting structure of a municipal sewage pipeline comprises the sewage pipeline in embodiment 7, wherein the sewage pipeline comprises a first pipeline 1 and a second pipeline 2, wherein water flows sequentially pass through the first pipeline 1; the tip that second pipeline 2 is close first pipeline 1 is provided with the section of necking down 21, the outer wall evenly distributed of the section of necking down 21 has a plurality of recesses 22, set up caulking groove 11 on the 1 inner wall of first pipeline, be provided with in the recess 22 and can insert and locate the sectorial scalable stopper 23 of caulking groove 11 in order to be connected first pipeline 1 and second pipeline 2, scalable stopper 23 is provided with limit stop 24 in the end wall in recess 22, be provided with in the recess 22 with the elastic component 25 that scalable fixture block compressed tightly to caulking groove 11 direction.
When the pipeline is installed, the necking section 21 is installed at one section of the first pipeline 1, then the second pipeline 2 is pushed to continue to move, the telescopic limiting block 23 can be contracted in the groove 22 at the moment until the second pipeline 2 moves, the telescopic limiting block 23 is aligned to the caulking groove 11, the telescopic limiting block 23 can extend out of the groove 22, the caliper of the groove 22 is arranged in the caulking groove 11, and the telescopic limiting block 23 is tightly pressed in the caulking groove 11 by the tension of the spring.
In practical application, the whole system of the sewage discharge pipeline comprises a plurality of sewage discharge pipelines, so that when in connection, a necking section 21, a groove 22, a telescopic limiting block 23 and an elastic part 25 are usually arranged on the next pipeline through which water flows, and an embedded groove 11 is arranged on the previous pipeline for installing the subsequent sewage discharge pipeline.
After the sewage pipes are connected, a water leakage phenomenon may occur, so that an annular L-shaped boss 12 is arranged on the inner wall of the first pipe 1, one edge of the L-shaped boss 12 is opposite to the second pipe 2 and is distributed, an annular groove 26 is arranged at the end part of the second pipe 2 opposite to the first pipe 1, a framework oil seal 261 is arranged in the annular groove 26, and the edge of the L-shaped boss 12 opposite to the second pipe 2 is embedded in the framework oil seal 261 in a clamping manner; the edge of the L-shaped boss 12 close to the framework oil seal 261 comprises a trapezoidal section 121 connected with the other edge and a rectangular section 122 installed in the framework oil seal 261, and the large end of the trapezoidal section 121 faces the water flow direction.
