Problems solved by technology

[0003] The mass per unit area of ​​conventional waterproof blanket is 4800g / ㎡. If it is used on the side wall and arch of the tunnel, the weight of the waterproof blanket itself is relatively heavy and it is not easy to fix it. The water-absorbing material in the waterproof blanket is easy to move and cause uneven thickness, which increases the difficulty of construction. , also reduces the waterproof effect of the waterproof blanket

Abstract

The invention relates to a natural sodium-lithium base bentonite waterproof blanket, and the blanket comprises a woven cloth layer; an antibacterial breathable layer is arranged below the woven cloth layer, a first water storage layer is arranged below the antibacterial breathable layer, a breathable layer is arranged below the first water storage layer, a second water storage layer is arranged below the breathable layer, and an anti-skid bottom layer is arranged below the second water storage layer; a plurality of uniform thin distribution layers are uniformly distributed among the woven cloth layer, the antibacterial breathable layer, the first water storage layer, the breathable layer, the second water storage layer and the bottom layer. The invention has the advantages of air permeability, high-strength water absorption capacity and uniform thickness, and can be conveniently mounted on any object.

Description

technical field [0001] The invention relates to the technical field of waterproof blankets, in particular to a natural sodium-lithium-based bentonite waterproof blanket. Background technique [0002] As a new type of environmentally friendly and ecological composite anti-seepage material, sodium-based bentonite waterproof blanket has been widely used in civil engineering such as water conservancy, environmental protection, transportation, railway, and civil aviation due to its unique anti-leakage performance. Foundation treatment and capping of landfills, anti-seepage of artificial lakes, reservoirs, channels, rivers, roof gardens, anti-seepage of underground buildings such as basements, subways, tunnels, and underground passages. [0003] The mass per unit area of ​​conventional waterproof blanket is 4800g / ㎡. If it is used on the side wall and arch of the tunnel, the weight of the waterproof blanket itself is relatively heavy and it is not easy to fix it. The water-absorbin...
