2023-07-28

Composite drainage network is a drainage system that comprehensively utilizes various drainage technologies. It combines artificial drainage system and natural drainage system to form a complete drainage network. Its purpose is to solve urban drainage problems, reduce flood disasters, and improve water resource utilization efficiency in the process of urbanization.

The composite drainage network includes a variety of drainage methods, such as rainwater pipe network, sewage pipe network, landscape water system, etc. Among them, the rainwater pipe network is used to collect and discharge rainfall, the sewage pipe network is used to collect and treat urban sewage, and the landscape water system is used to collect and use rainwater for greening and landscape water. These different drainage systems are connected by pipe networks to form a complete drainage network.

The advantage of the composite drainage network is that it can flexibly combine and adjust various drainage systems according to different drainage needs. For example, in arid areas, the proportion of landscape water systems can be increased to improve the efficiency of rainwater use; while in rainy areas, the capacity of rainwater pipe networks can be increased to improve drainage capacity. Due to the complementary and coordinated relationship between different drainage systems, the composite drainage network can better adapt to different geographical and climatic conditions.

Composite drainage nets also have the advantage of saving energy and reducing emissions. The energy consumption and maintenance costs of drainage pumping stations can be reduced through rational configuration and operation of drainage systems. At the same time, through sewage treatment and rainwater utilization, the demand for natural water resources can be reduced, and the impact of sewage discharge on the water environment can be reduced.

However, composite drainage networks also face some challenges and problems. First of all, the construction and maintenance of different drainage systems require a lot of capital and technical support, and require the joint efforts of the government and society. Secondly, the design and operation of the composite drainage network requires professional knowledge and technical support, and requires the participation of relevant departments and professionals. Finally, the construction and operation of composite drainage networks need to be combined with urban planning and construction, and the needs of urban development and environmental protection need to be considered as a whole.

To sum up, the composite drainage network is a drainage system that comprehensively utilizes multiple drainage technologies, which can solve urban drainage problems, reduce flood disasters, and improve the utilization efficiency of water resources. However, the construction and operation of the composite drainage network requires the joint efforts of the government and the society, requires professional knowledge and technical support, and needs to be combined with urban planning and construction. Only through the cooperation and efforts of all parties can we build an efficient and sustainable composite drainage network and contribute to the sustainable development of the city.

What is the role of geomembrane?

Corrosion resistance, low temperature resistance, good cold resistance. The main mechanism is that the imperviousness of the plastic film intercepts the leakage channel of the earth dam, withstands the water pressure with greater tensile strength and elongation, and adapts to the deformation of the dam. Non-woven fabrics are also high-molecular staple fiber chemicals, which have high tensile strength and ductility through impregnation or thermal viscosity. Combining with plastic films not only increases the tensile strength and puncture resistance of plastic films, but also due to non-woven The surface of the cloth is rough, which increases the friction coefficient of the contact surface and contributes to the stability of the composite geomembrane and the protective layer. At the same time, they are highly corrosive to bacteria and chemicals, and are not afraid of acid, alkali, and salt erosion.

Rough surface HDPE geomembrane

Rough HDPE geomembrane, that is, high-density polyethylene geomembrane, is a kind of anti-seepage material commonly used in engineering construction. It has a certain rough texture, which can increase the friction with other materials and improve the stability and anti-slip performance of the geomembrane. The following will introduce the characteristics, application fields and construction precautions of the rough HDPE geomembrane.

Geocell

A geocell is an engineering structure used for soil improvement and soil and water conservation. It is usually composed of geotechnical materials, such as geotextiles, geonets and geomembranes. The main function of geocells is to increase the shear strength and stability of the soil and prevent geological disasters such as soil erosion and landslides. The characteristics, application and construction process of geocells will be introduced in detail below.
