In the field of water conservancy engineering, channel drainage is very important. It is not only related to the utilization of water resources, but also directly affects the safety and stability of the channel and its surrounding structure. Composite drainage network It is a material commonly used in channel drainage, so what are its specific applications in channel drainage?
1. Characteristics of composite drainage network
Composite drainage net is a new type of drainage geotechnical material composed of three-dimensional plastic net bonded with water-permeable geotextile on both sides. It has the following properties:
1、High drainage performance: The composite drainage network has extremely high drainage performance, which can quickly and effectively drain the accumulated water in the channel and keep the channel dry and stable.
2、Good tensile strength: It is composed of high-strength plastic net and geotextile. The composite drainage net has very good tensile strength and can withstand large loads without deformation or cracking.
3、Corrosion resistance and aging resistance: The materials used in the composite drainage net have very good corrosion resistance and aging resistance, and can be used for a long time under harsh environmental conditions without failure.
4、Easy construction: The composite drainage net is light in weight and flexible, making it easy to transport and construct. Its unique structure also makes the construction process simpler and faster, which can greatly shorten the construction period.
2. Application advantages of composite drainage network in channel drainage
1、Improve drainage efficiency: The high drainage performance of the composite drainage network can quickly discharge the accumulated water in the channel, which can avoid the erosion and damage of the channel and its surrounding structures caused by the accumulated water.
2、Enhance channel stability: Laying a composite drainage network can disperse the load at the bottom of the channel, enhance the stability of the channel, and prevent the channel from deforming or collapsing due to excessive load.
3、Extend service life: The corrosion resistance and aging resistance of the composite drainage net allow it to be used in channel drainage for a long time without failure, which can prolong the service life of the channel.
4、Reduce maintenance costs: The composite drainage network has very good drainage performance and stability, which can reduce the frequency and cost of channel maintenance and save a lot of money for water conservancy projects.
3. Construction points and matters needing attention
1、Construction preparation: Before construction, the channel should be thoroughly cleaned and leveled to ensure that the bottom of the channel is flat and free of debris. It is also necessary to cut a composite drainage network of appropriate size according to the design requirements and actual conditions of the channel.
2、Laying method: Lay the cut composite drainage net flat at the bottom of the channel, making sure it covers the entire drainage area. During the laying process, it is necessary to keep the composite drainage net flat and tightly fit the bottom of the channel.
3、Fixing method: In order to prevent the composite drainage net from moving or floating during the drainage process, an appropriate fixing method should be adopted. Commonly used fixing methods include nail fixation, layering fixation, etc.
4、Joint treatment: When multiple pieces of composite drainage net need to be spliced, ensure that the joints are tight and seamless. Joint treatment can be done using special glue or hot melt welding, etc. to ensure drainage effect.
