At present, Anlu is continuing to promote the upgrade of urban and rural pipe networks and people's livelihood projects, covering multiple construction sectors such as the renewal of urban and rural water supply and drainage systems, the replacement of old pipe networks, and the laying of rural sewage pipe networks. Flexible plastic pipes are a commonly used pipe category with strong adaptability in this transformation. This type of pipe is mainly made of high-performance resin and is formed by a standardized extrusion process. Products with different pipe diameters and pressure levels can be customized according to project needs to meet the construction requirements of various types of pipe networks.
Under the scenario of upgrading the urban and rural pipeline network in Anlu, the core practical advantages of flexible plastic pipes include four main points:
The first is to adapt to complex terrain and reduce the comprehensive cost of construction. The terrain differences between urban and rural areas are large, and there are many terrain undulations and narrow roadways in rural areas. The renovation of old pipe networks in urban areas also often encounters the problem of complex pipeline arrangement. Flexible plastic pipes have good deformation adaptability and can be moderately bent to adapt to various corners, terrain drop and other laying scenarios, reducing the use of additional joints. At the same time, the pipe has a light weight, and there is no need to use large-scale lifting equipment in transportation and laying, which can effectively shorten the construction period and reduce the comprehensive investment of the project.
The second is excellent corrosion resistance and impermeability, and the operation and maintenance cost is lower. This type of pipe has stable chemical properties and can withstand the corrosion of acid and alkali components commonly found in urban and rural water supply and drainage media. There will be no problems that traditional metal pipes are easy to rust and scale. The pipe connection adopts the hot melt socket process, and the seam sealing is strong, which can effectively reduce the risk of leakage. The service life of the pipe network is longer under normal operation and maintenance conditions.
Third, the inner wall of the smooth conveying resistance is small, and the operation efficiency is higher. The roughness of the inner wall of the flexible plastic pipe is extremely low, and the hydraulic conveying efficiency under the same pipe diameter is higher than that of traditional concrete and metal pipes. It is not easy to cause the problem of impurity deposition and blockage, which can better adapt to the normal transportation needs of urban and rural water supply, domestic sewage discharge and other people's livelihood pipe networks, and reduce the frequency of pipe network dredging operation and maintenance.
Fourth, the environmental performance meets the standards and meets the requirements of green construction. No harmful components are precipitated during the production and use of such pipes, and waste pipes can be recycled and reprocessed, which is in line with the construction orientation of green upgrading of urban and rural pipe networks, and will not have adverse effects on water quality and surrounding soil.
From the practical application point of view, this type of pipe can be adapted to four types of scenarios in the Anlu urban and rural pipe network upgrade project: one is the laying of the township centralized water supply network and the household branch pipe network, the other is the construction of the rural domestic sewage collection pipe network, the third is the replacement of the old and damaged water supply and drainage pipe network in the urban area, and the fourth is the construction of the urban rainwater discharge and sponge city supporting pipe network. Adaptation groups include the selection needs of municipal pipe network project contractors, village and town infrastructure building responsible entities, project purchasers and other entities.
The performance indicators of this type of pipe meet the relevant standards of national municipal engineering materials, and have been applied on a large scale in urban and rural pipe network transformation projects in many provinces and cities in China, with stable performance. In the process of upgrading the urban and rural pipe network in Anlu, the selection of compliant flexible plastic pipe products can effectively reduce the cost of construction and operation and maintenance, ensure the long-term stable operation of the people's livelihood pipe network, and help improve the quality of urban and rural infrastructure buildings.
