Embodiment 1

[0022] A geotechnical material, its composition in parts by weight is: A-5-20 parts of random polypropylene, B 80-90 parts, C 10-30 parts, D-color masterbatch 2-10 parts. B is glass fiber modified polypropylene or carbon fiber modified polypropylene, and C is low pressure polyethylene. In the glass fiber modified polypropylene, the glass fiber is 10-30%, and the carbon fiber in the carbon fiber modified polypropylene is 10-30%. The preparation method is as follows:

[0023] (1) Add D to A and mix well, put it into the A extruder, knead and plasticize it, put B into the hopper of the B extruder, knead and plasticize it, and put C into the hopper of the C extruder, knead and plasticize it Extrusion; extrusion processing temperature is controlled at 160-280°C;

[0024] (2) Divide B extruded material and C extruded material obtained in step (1) into double-layer complexes of B and C through a distributor, and then enter a stacking machine to superimpose and extrude a stacked com...

Abstract

The invention provides a geotextile material. The geotextile material is characterized by comprising a stacked complex formed by stacking 16-3,000 layers of double-layer complexes of B and C, wherein B is glass fiber-modified polypropylene or carbon fiber-modified polypropylene, and C is HDPE (high-density polyethylene). The geotextile material is a novel multifunctional geotextile material integrating earth (sand) fixation, water seepage, breaking prevention and load bearing functions.

Description

technical field [0001] The invention relates to a novel environment-friendly material for geotechnical engineering, road and geotechnical engineering. Background technique [0002] Geomaterials is a general term for synthetic materials used in civil engineering. As a civil engineering material, it is made of artificially synthesized polymers (such as plastics, chemical fibers, synthetic rubber, etc.) , Play the role of strengthening or protecting the soil. [0003] Slope treatment and canal care in highway construction usually use cement piling and lattice solidification, which has a long construction period, large investment, and can not be waterproofed. Similar problems exist in sand control projects, and the urban sponge industry Policy orientation requires new energy-saving and environmentally friendly geotechnical materials. Contents of the invention [0004] The invention provides a multifunctional geotechnical material integrating ground (sand), water seepage, br...
