thermobonding three layer drainage: It is a three-dimensional polypropylene mesh pad that forms a w-shaped longitudinal full-section drainage channel through special extrusion and two layers of needle-punched and heat-treated non-woven geotextiles to form anti-filtration, drainage, and protection through thermal bonding. thermobonding three layer drainage structure, where the unit area mass of the drainage core material is 420g / ㎡ (tolerance ± 10%), the unit area mass of the reverse filter layer is 105g / ㎡ (tolerance ± 15%), the longitudinal tensile strength is 14kn / m, 50kpa, hydraulic When the gradient i = 1, the plane water flow is 1.5x10-³㎡ / s, 100kpa. When the hydraulic gradient i = 1, the plane water flow is 1.3x10-³㎡ / s.

When the hydraulic gradient i = 1, the plane water flow is 1.3x10-³㎡ / s.
A microphone drainage pad is arranged on the inner slope of the retaining wall. The three-dimensional polypropylene mesh pad formed by special extrusion to form a "W" -shaped longitudinal full-section drainage channel and two layers of non-woven geotextile form thermal filtration, drainage, and drainage. Protected three-dimensional drainage mat.
The outer slope of the retaining wall is reinforced by spraying greening. The height of the 16m end of the retaining wall is relatively large, and a cone slope needs to be set. The cone slope is synchronized with the retaining wall to ensure the stability of the retaining wall.3. Φ8 steel bar is used to make U-shaped metal anchors. The microphone pad is fixed on the slope. The anchors are anchored to the ground through the wire mesh. Make an effort and keep the slope stable. Anchor trench For excavating a ditch 0.6-1m, 0.3m deep and 1m wide from the slope edge, anchor the Mike pad along the trench bottom. In general, simply folding the microphone pad along the slope can fix it to the slope.
