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.

Examples

Embodiment 1

[0022] A geotechnical material, its composition in parts by weight is: 5-20 parts of A-random polypropylene, 80-90 parts of B, 10-30 parts of C, and 2-10 parts of D-color masterbatch. 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, mix well, and put it into the A extruder for kneading and plasticizing; B is put into the hopper of the B extruder for kneading and plasticizing; C is put into the hopper of the C extruder for kneading and plasticizing 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 superi...
