一. Basic structure and performance of three-dimensional drainage network
1、The three-dimensional drainage net consists of a three-dimensional geonet core and two-sided needle-punched and perforated non-woven geotextile. The core part of the mesh has a thick vertical rib and an oblique rib at the top and bottom, forming a three-dimensional space structure. This structure not only increases the strength and rigidity of the drainage network, but also allows it to withstand high compressive loads, maintain a considerable thickness, and provide good hydraulic conductivity.
2、The three-dimensional drainage network can quickly discharge the groundwater of the road. Through its unique pore maintenance system, it blocks capillary water under high load, and can prevent the groundwater from accumulating and softening. Three-dimensional drainage network can also play the role of isolation and foundation reinforcement, limit the lateral movement of aggregate base layer, and improve the supporting capacity of foundation.
二. Influence of the shape of the stiffening sleeve on the performance of the three-dimensional drainage network
Stiffener sleeve is the key component that connects three-dimensional drainage network with foundation or other structures, and its shape has an important influence on the performance of drainage network.
1、Enhanced connection stability
The shape design of the stiffening sleeve should take into account the close fit with the foundation or other structures. A reasonable shape of the stiffening sleeve can ensure that the connection between the drainage net and the foundation is more stable, and prevent the drainage net from displacing or falling off when stressed. This stability is very important for the long-term operation of the drainage network and the stability of the foundation.
2、Optimize drainage effect
The shape of the fixing sleeve will also affect the drainage effect of the drainage net. If the design of the fixed stiffening sleeve is unreasonable, it may lead to poor drainage channels and affect the drainage speed and efficiency of the drainage network. On the contrary, a reasonable shape of the stiffening sleeve can ensure that the drainage channel is unimpeded, so that the drainage network can quickly discharge the accumulated water in the foundation, reduce the water content of the foundation, and improve the strength and stability of the foundation.
3、Improve construction efficiency
A reasonable shape of the stiffening sleeve can also improve the construction efficiency. The easy-to-install and disassemble shape of the fixed stiffening sleeve can reduce the difficulty and complexity in the construction process, shorten the construction period and reduce the construction cost.
三. Design principles of the shape of the fixed sleeve of the three-dimensional drainage network
1、Principle of close fit: The shape of the stiffening sleeve should match the shape of the foundation or other structures to ensure close fit and prevent displacement or falling off.
2、Principle of drainage efficiency: The design of the fixed stiffening sleeve should take into account the smoothness of the drainage channel to ensure that the drainage network can quickly discharge the accumulated water in the foundation.
3、Principle of convenient construction: The shape of the fixed stiffening sleeve should be easy to install and disassemble, which is convenient for construction personnel to operate and improve construction efficiency.
4、Durability principle: The material of the fixing sleeve must have very good corrosion resistance and anti-aging properties to ensure long-term stable operation.
It can be seen from the above that the shape of the stabilizer sleeve of the three-dimensional drainage network has an important influence on its performance. A reasonable shape of the stiffening sleeve can enhance the connection stability, optimize the drainage effect, improve the construction efficiency and meet the requirements of durability. In practical projects, it is necessary to carefully design the shape of the fixed stiffening sleeve according to the specific situation, so as to ensure that the performance of the drainage network can be fully exerted.
