Description

technical field

[0001] The invention relates to the technical field of geological disaster prevention engineering, in particular to a hard organic framework filling material and a preparation method thereof. Background technique

[0002] Karst landforms are widely distributed in my country, and the distribution area of ​​karst areas in the country is about 1.3 million km 2 , the most prominent areas are Guangxi, Guangdong, Yunnan, Guizhou, Sichuan, Hubei, Hunan, etc., and the distribution area accounts for about 1 / 2 of the national distribution area. In the karst area, the lithology is carbonate, which is prone to dissolution to cause damage to the rock mass structure, resulting in a large number of underground runoff channels such as caves, fissures, and underground rivers. In the karst area, the surface water system is generally not developed, and the groundwater resources are abundant. Due to the years of groundwater runoff, the erosion effect will cause the underground ...

Examples

preparation example Construction

[0039] A method for preparing a hard organic framework filling material, comprising the steps of:
