Problems solved by technology
[0002] Most of the existing waterproof blankets have two layers, the upper layer is a plastic flat wire woven geotextile layer, and the lower layer is a non-woven geotextile layer. The waterproof blanket with this structure has a short service life and poor anti-seepage and water-blocking effect, and cannot be used for a long time. Meet the requirements of use, prone to water seepage and water leakage accidents

Abstract
The invention relates to a novel composite waterproof carpet. The novel composite waterproof carpet comprises a waterproof carpet main body, wherein the waterproof carpet main body is divided into two layers; the upper layer is a non-woven cloth layer; the lower layer is a non-woven geotechnical cloth layer; a plurality of concave pits are formed on the surface of the non-woven geotechnical cloth layer and internally provided with water absorption dilatants; and the non-woven cloth layer is connected with the non-woven geotechnical cloth layer in a sewing manner. The novel composite waterproof carpet is simple in structure and low in production cost; non-woven cloth is arranged at the upper layer, so that the carpet is bright in color and attractive in appearance; non-woven geotechnical cloth is arranged at the lower layer, so that the carpet is good in abrasive resistance and long in service life, can be widely applied to industries of municipal engineering, water conservancy, gardens, families and the like, and is wide in application scope; when the carpet meets water, sodium bentonite particles absorb water and expand to form a compact gel structure, and water molecules cannot penetrate, so that the carpet has seepage control and water resistance effects, and the permeability coefficient of the carpet can reach as high as 10-9cm / s.
Description
technical field [0001] The invention relates to a novel composite waterproof blanket, in particular to a novel composite waterproof blanket. Background technique [0002] Most of the existing waterproof blankets have two layers, the upper layer is a plastic flat wire woven geotextile layer, and the lower layer is a non-woven geotextile layer. The waterproof blanket with this structure has a short service life and poor anti-seepage and water-blocking effect, and cannot be used for a long time. It meets the requirements of use, and it is prone to water seepage and water leakage accidents. Contents of the invention [0003] In order to solve the above problems, the present invention provides a novel composite waterproof blanket with simple structure, good waterproof effect and convenient use. [0004] The technical solution of the present invention is: comprising a waterproof blanket main body, the waterproof blanket main body is divided into two layers, the upper layer is a...
