The invention provides a large-caliber polyethylene (PE) plastic pipeline construction structure and a construction method. A pipeline passes through a riverway underground laying structure, a curingagent is adopted to cure sludge in a riverway, steel tube columns are arranged in the riverway for effecting a profile steel framework, an anti-sliding steel plate is laid on the profile steel framework as a temporary shortcut, and a precast concrete foundation is arranged shoreside to support the profile steel framework; steel plate columns are adopted in the riveryway for erecting a steel platepile cofferdam, geotechnical cloth, a grid mesh, bagged soil and a waterproof plate arranged on an upstream face of the steel plate pile cofferdam for reinforcing; the lower part of the pipeline is provided with a prefabricated base and a cushion layer, and the prefabricated base is fixed through a fixing screw and the cushion layer; and the top of the steel plate pile cofferdam is heightened by aheightening water baffle plate. For pipeline mounting on a roadbed, the pipeline passes through a roadbed underground laying structure to construct, and a pipeline passes through a bridge sidewalk underground laying structure to construct for pipeline mounting on a bridge, so that engineering cost is effectively reduced, and construction speed is increased.
Description
technical field [0001] The invention relates to the field of civil engineering, in particular to a large-diameter polyethylene (PE) plastic pipe installation structure and a construction method, which are suitable for the construction of the large-diameter polyethylene (PE) plastic pipe installation structure. Background technique [0002] With the development of social economy, the application of plastic pipes is more and more extensive. Polyethylene (PE) pipes have many excellent characteristics, such as low temperature resistance, good toughness, hardness and softness, etc., so they are used in some special purposes. In some fields, pipes made of traditional materials are not suitable, or they are expensive, and they cannot be used safely. Some pipes made of traditional materials are prone to problems such as corrosion and joint leakage. Polyethylene (PE) pipes have successfully solved these two problems. [0003] However, the following problems are prone to occur in co...
