Technical Field
[0001] The utility model relates to the technical field of pressure-resistant water pipes, in particular to an underground pressure-resistant water pipe. Background Art
[0002] In modern infrastructure construction, buried pressure-resistant water pipes play a vital role. Buried pressure-resistant water pipes need to have excellent performance to cope with complex underground environments. First of all, they should have excellent pressure resistance, be able to withstand the weight of the soil and various pressures that may be applied on the ground, and ensure that they will not be deformed or damaged by external pressure during long-term use. When selecting buried pressure-resistant water pipes, many factors need to be considered comprehensively. Including the specific needs of the project, geological conditions, use environment, cost budget, etc. At the same time, it is also necessary to ensure the standardization and rigor of the installation process to give full play to the performance of the water pipe. In short, buried pressure-resistant water pipes are an indispensable part of infrastructure construction, and their quality and performance are directly related to the stable and reliable operation of the entire system. We must attach great importance to the selection and application of buried pressure-resistant water pipes to ensure the normal operation and development of society.
[0003] At present, most of the underground pressure-resistant water pipes are made of high-density PE material. By taking advantage of the good pressure resistance and impact resistance of high-density PE, the underground pressure-resistant water pipes can be buried deep underground for use. However, relying solely on the strength of the high-density PE material itself, the underground pressure-resistant water pipes can only be used in shallow underground layers. When used in deeper underground layers, the high-density PE will deform due to pressure. At the same time, the conventional underground pressure-resistant water pipes made of high-density PE material do not have thermal insulation properties, which is inconvenient to use.
