According to the current situation of the facilities under the municipal roads in China, different pipelines such as electric power, communication, coal gas, water supply, drainage pipelines and the like are generally arranged, and the drainage pipelines take measures of rainwater and sewage diversion into consideration, namely rainwater is generally discharged into rivers nearby, and sewage is discharged into a sewage treatment plant, so the drainage pipelines comprise two pipelines of rainwater and sewage. At present, three types of pipes are commonly used in drainage engineering, namely a reinforced concrete pipe which is large in rigidity, low in manufacturing cost, various in connector form and wide in application range, but has a rough inner wall, large friction resistance and poor corrosion resistance, and a plastic pipe which is smooth in inner wall, small in friction resistance coefficient, good in corrosion resistance and sealing performance, long in service life, but low in rigidity and low in external pressure resistance; and thirdly, the glass fiber reinforced plastic pipeline has excellent corrosion resistance, long service life, lower rigidity and low external pressure resistance. Although the concrete pipe in the drainage pipe of patent No. CN200820078633.4 is lined with a polyvinyl chloride pipe, because of the property characteristics of polyvinyl chloride, even if the polyvinyl chloride pipe is lined in the concrete pipe, the polyvinyl chloride pipe has a large expansion coefficient, and when the polyvinyl chloride pipe is used in long-distance drainage engineering, temperature compensation needs to be considered, and in the patent, multiple sections of pipelines are connected only by sealing paste, and the influence of pressure generated during pipeline jacking construction on a connection structure is not considered, and jacking construction is not applicable.
