Geosynthetic material

Abstract

The invention discloses a geosynthetic material. The geosynthetic material is characterized by being prepared in accordance with the following formula comprising raw materials in parts by weight as follows: 30-60 parts of cement, 10-50 parts of synthetic fibers, 2-8 parts of an activator, 2-5 parts of slaked lime, 0-10 parts of calcium chloride, 0-5 parts of a water reducing agent and 20-60 parts of water. The fibers are adopted as the main material and adopt a filament needle-punched nonwoven fabric structure, so that the materials are cluttered to form a net, the strength is very high, the difference between the longitudinal strength and the transverse strength is small, effects of locking soil and reducing soil erosion can be realized, and the material is suitable for soil with loose structure.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a geosynthetic material. Background technique [0002] Geosynthetics is a new type of geotechnical engineering material with great vitality and high application value. Non-woven geotextiles are widely used in engineering, and the amount is increasing year by year. Especially in water conservancy projects, the largest amount is used to replace sand and stone as reverse filter layers. Secondly, it is also used in different degrees in various projects such as electric power, highways, railways, reclamation, environmental protection, airports, etc., mainly based on reverse filtration. At the same time, it can also play the role of isolation and drainage. [0003] The publication number is CN1458106, which reports a lightweight geosynthetic material "made with fly ash and foamed plastics as the main components, supplemented with active ingredients and stirred with water". The material i...

Problems solved by technology

[0004] Although the above-mentioned invention can effectively strengthen the stability of soft clay, as in the northwest, the soil is loose in structure and poor in impact and corrosion resistance, and the above-mentioned materials cannot achieve the purpose of soil consolidation at all.
