secondly, respectively placing plugging components in the anti-blocking structure of the power pipeline at two ends of the pipeline, wherein a plugging part in the anti-blocking structure of the power pipeline containing a through hole faces to the pipe orifice, the distance between the end part of the plugging part at the outer side of the component and the pipe orifice is not less than 50mm, and simultaneously preventing a threaded shaft in the plugging component from extending out of the pipe orifice; rotating a threaded rod and a threaded shaft in the anti-blocking structure of the electric power pipeline to enable two opposite blocking parts to be close to each other, and enabling the spring to be compressed for a distance which is smaller than the limit compression distance of the spring; rotating the threaded shaft to enable the two moving parts to approach and respectively contact the plugging part; screwing out the threaded rod, and rotating the threaded shaft to enable the moving part to abut against the blocking part and be pre-tightened;
thirdly, installing a rubber cover on the pipe orifice; packing the end of the calandria; removing the mold and maintaining; removing the sealing soil when the cable is installed, and cleaning sludge impurities at the pipe orifice;
inserting the threaded rod into the blocking part and screwing the threaded rod into the through hole in the blocking part and the second threaded hole at one end of the threaded shaft, and rotating the threaded shaft to enable the moving parts to be away from each other; the threaded rod is rotated to compress the spring, the plugging component is pulled out by the threaded shaft and the threaded rod, and the power cable is put in.
9. The construction method of the anti-clogging structure for the power pipeline according to claim 8, characterized in that in the step (i), the cross-sectional shape of the foundation pit is divided into a trapezoidal cross-section and a rectangular cross-section according to the number or type of the required laid pipelines; a plurality of layers of pipelines are sequentially distributed in the foundation pit with the trapezoidal section from the bottom to the top; a plurality of layers of pipelines with the same number are distributed in the foundation pit with the rectangular section; and a reinforcing frame is arranged below each layer of pipeline in the foundation pit.
10. The construction method of the anti-clogging structure for the power pipeline according to claim 8, wherein in the second step, two ends of each pipeline are respectively provided with a plugging component, a threaded shaft in each plugging component is hollow, and the two plugging components are connected and tensioned with each other through a steel wire rope.
