Abstract

The invention discloses a sodium bentonite waterproof blanket and a construction method thereof. According to the sodium bentonite waterproof blank, a polygonal columnar flow guide groove is formed between fabric face cloth and fabric bottom cloth; a frame of the flow guide groove defines a cavity; a plurality of through water permeable holes are formed in the upper edge of the frame; a distance is reserved between the lower edge of the frame and the fabric bottom cloth; the frame is filled with quick set dry-mixed mortar; and the space between the fabric face cloth and the fabric bottom clothand the space defined by the flow guide groove are filled with sodium bentonite powder. When the sodium bentonite waterproof blanket is used, accumulated water on the surface of a water permeable concrete pavement or slope or the like can seep into the fabric face cloth of the sodium bentonite waterproof blanket, the through water preamble holes are formed between the fabric face cloth and the cavity of the flow guide groove, thus the seeped water can enter the cavity to drain away, and the problem that the accumulated water remaining between the sodium bentonite waterproof blanket and the concrete pavement or the slope causes soaking damage to the concrete pavement or slope is solved.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a sodium-based bentonite waterproof blanket and a construction method thereof. Background technique [0002] Bentonite waterproof blanket is a geosynthetic material specially used for anti-seepage in artificial lake water features, landfills, underground garages, roof gardens, pools, oil depots and chemical storage yards. It is made of highly expansive sodium-based bentonite filled between the special composite geotextile and non-woven fabric. The bentonite anti-seepage pad made by needle punching can form many small fiber spaces, so that the bentonite particles cannot flow and meet water. A uniform high-density colloidal waterproof layer is formed in the pad, which can effectively prevent water leakage. [0003] At present, according to the production process, bentonite waterproof blanket can be divided into: sodium bentonite waterproof blanket by acupuncture meth...
