Product Description

Product Description

Composite drainage network is a new type of drainage geotextile material, mainly composed of high-density polyethylene as raw material, processed through special extrusion molding technology, with a three-layer special structure. The middle reinforcement bar is rigid and longitudinally arranged to form a drainage channel. The cross arranged reinforcement bars form a support to prevent the geotextile from being embedded in the drainage channel, and can maintain high drainage performance even under high loads. The composite use of double-sided adhesive permeable geotextile has the comprehensive performance of "filtration drainage breathability protection" and is currently the drainage material.

The three-dimensional composite drainage network is a material produced by pressing, mainly using high-density polyethylene (HDPE) as the raw material. The overall structure is quite distinctive, with a three-layer structure, high rigidity, vertically arranged to form drainage channels, and has a certain support force, which can prevent situations where water cannot be discharged under stress. Even under pressure, being able to discharge water is something that many materials cannot achieve today.
 

The characteristics of three-dimensional composite drainage network:

In addition, this material also has an isolation effect, separating the aggregate layer and limiting its movement. Generally speaking, this material has better tensile strength than geogrids, providing support. After the road surface ages and cracks form, a large amount of rainwater enters the cross-section. In this regard, the three-dimensional composite drainage network will be directly laid under the road surface to replace the drainage foundation. This structure can extend the service life of both hard and flexible pavement systems.The characteristics of three-dimensional composite drainage network:

Installation Instructions

Before laying the composite drainage network, the foundation should be carried out. Firstly, the next layer should be leveled and compacted, with a flatness not exceeding 15mm and a density that meets the design requirements. The surface must not have hard and protruding objects such as gravel and gravel. Paving the natural environment; Outdoor temperature above 5 ºC, wind below level four, no rain or snow. In case of special circumstances, construction must be carried out in a natural environment and protective measures should be taken.

When paving the composite drainage network, it should be flat and level, and not crooked or stretched. Overlapping areas should be fixed with U-shaped nails or connectors. The direction of the main compressive strength of the reinforcement should be perpendicular to the direction of the dam foundation, and the length of each overlapping steel bar should be equivalent to the main compressive strength of the building steel bar. The overlap (vertical) should not be less than 15 centimeters, fixed with U-shaped nails or connectors at intervals of 1.0 meters. The length of the horizontal steel bars should be 30-90 centimeters, and the overlapping parts of the steel bars should be fixed with U-shaped nails or plastic ropes.
 

Subsequently, backfill soil was carried out to solve the problem. The filling material for the dam foundation within the scope of the composite drainage network should not exceed a larger diameter of 6cm. The first layer of the composite drainage network should use a lightweight excavator or front small shovel truck, and the road should be compacted along the embankment direction. The compacted thickness should exceed 60cm. After the raw materials of the composite drainage network are paved in a timely manner, filling materials should be added immediately to prevent prolonged exposure to the sun. The general time interval should not exceed two days.
