FILLING MATERIAL AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/123141
Kind Code:
A1
Abstract:
A filling material and the use thereof. The material comprises a first component and a second component, wherein the first component comprises biogum, a first stabilizer and a second stabilizer, the biogum comprising guar gum, and the biogum further comprising at least one of xanthan gum, Arabic gum, carrageenan, mannan, locust bean gum, carboxymethyl cellulose and gellan gum; and the second component is a hydrolysate. When the material is used for building a permeable reactive barrier, a supporting force can be provided for a trench wall, such that the problem of falling off does not occur on the soil on a trench wall of the reactive barrier, the trench wall also does not collapse, and the built reactive barrier has a uniform shape and has no defects, such that the repair effect of the permeable reactive barrier on soil or underground water is ensured; and plate-shaped support and protection are not needed when the permeable reactive barrier is built, thereby reducing the production cost.
