1,Introduction

Composite Dimple geomembrane (also known as three-dimensional composite drainage network, drainage grid) is a new drainage geotextile material. High density polyethylene (HDPE) as raw material, processed by a special extrusion process is made with three special structure. Intermediate rib rigidity, longitudinally arranged to form a drain passage, the vertical arrangement of the cross ribs form a support to prevent the geotextile embedding drain passage, even at very high loads can be maintained high drainage performance. Double-sided adhesive seepage geotextile composite use, with "filtration - Drainage - breathable - Protection" overall performance, is the ideal drainage material.

2,Feature

(1) Drainage and strong (equivalent to one meter thick gravel drainage).

(2) high tensile strength.

(3) reduce the probability of geotextile embedded network core, to maintain long-term stability of the drainage.

(4) long withstand high pressure loads (about 3000Ka can withstand compressive load).

(5) corrosion, acid, and long service life.

(6) construction convenient, shorten the construction period and reduce costs.

3, the structure introduced

(1) three-dimensional composite drainage board is a synthetic non-woven geotextile and geonet core structure consisting of a layer of a different one or two layers, with a composite structure and drainage isolation function;

(2) composite drainage board used in underground garage roof planting, planting roofs, underground sidewall protection, drainage, floor drainage, tunnel waterproofing, drainage, road slope, saline desert planting, artificial lakes;

(3) composite drainage board application functionality can be bent construction, rapid drainage hydrostatic waterproof layer, HDPE geomembrane water, in a timely manner to reduce the load of the main structure, waterproofing and structural protection, to avoid being backfilled soil, plant thorn, pH , insects and micro-organisms, such as the destruction of underground waterproof layer.

4.Application

The primary composite drainage board used in underground garage roof planting, planting roofs, underground sidewall protection, drainage, floor drain, Tunnel waterproofing, drainage, soft foundation treatment, subgrade enhancement, road slope, saline desert planting, artificial lakes; For railways, highways, tunnels, municipal engineering, reservoir, slope protection and drainage works in effect is remarkable.
