Problems solved by technology

However, under heavy rainfall conditions, a barrier of capillary air bubbles is often formed on the surface of the reinforced soil inner fabric layer, preventing rainwater from infiltrating, resulting in an increase in pore water pressure on the slope surface, resulting in slope instability or landslides.

Embodiment Construction

[0016] A breathable sap-coated composite material that prevents slope infiltration. Its overall structure includes three parts: sap-coated honeycomb grid, three-dimensional separation layer, and reinforced permeable layer.

[0017] The sap coated honeycomb grid in the structure 1) is formed by spraying sap superabsorbent resin material on each inner surface of the honeycomb plastic grid. When encountering moisture, the sap superabsorbent resin expands and blocks the honeycomb channel Closed, unable to pass water, when the environment is dry, sap super absorbent resin shrinks, sap coated honeycomb grid 1) opens the water passage;

[0018] The three-dimensional separation layer 2) in the structure is a plastic grid structure with a certain thickness, which separates two adjacent sap-coated honeycomb grids 1);

[0019] The reinforced permeable layer 3) in the structure is a square grid structure, made of plastic with tensile strength, and the warp and weft are interlaced to form ...

Abstract

The invention provides a breathable super absorbent polymer (sap) coating composite material for preventing slope surface infiltration and a manufacturing method thereof. The sap coating composite material is sandwiched by a sap coating honeycomb grille, a three-dimensional partition layer, and a reinforced permeable layer, the sap coating composite material is used in slope embankment filling surface waterproofing engineering and is particularly suitable for slope embankment filling engineering in areas with more rain in the south, seepage failure caused by infiltration of rainwater to the slope embankment can be significantly reduced or eliminated, drainage of rainwater from the surface of the slope embankment is accelerated, seepage flowing down the slope surface is reduced, soil body seepage damage is avoided, when the weather is fine, the sap coating composite material can shrink so that honeycomb ventilation holes are opened, and excessive moisture in the slope embankment is drained; and at the same time, according to the sap coating composite material, the anti-sliding performance of the slope soil body can be further improved, and the risk of landslides is lowered.

Description

technical field [0001] The invention relates to an air-permeable SAP coating composite material for preventing slope infiltration and a manufacturing method thereof. The sap-coated composite material is composed of a sap-coated honeycomb grid, a three-dimensional separation layer, and a reinforced permeable layer. The sap coating composite material is used in the surface waterproofing project of slope embankment filling, especially suitable for slope embankment filling projects in areas with a lot of rain in the south, which can significantly reduce or eliminate the infiltration of seepage rainwater on the slope embankment Destruction, speed up the discharge of rainwater from the surface of the slope embankment, reduce the downward seepage along the slope, and avoid soil seepage damage. In fine weather, the sap coating composite material can also shrink and open the honeycomb ventilation holes to discharge the rainwater in the slope embankment Excess moisture. At the same ti...
