Embodiment 1

[0020] Embodiment 1: a kind of sandwich sheet with skeleton material discretely distributed [such as figure 1 Shown) the manufacturing method and the geocell made of it.

[0021] Choose three PE fishing net wires (about 0.09mm in diameter) as the skeleton material, or one PE fishing net wire, one PP fishing net wire and one PET filament (all about 0.09mm in diameter) as the skeleton material; The plastic particles recovered from plastic film are non-skeleton materials and are co-extruded at the same extrusion head (the temperature of the extruder and the head is controlled at 80-100°C, and the three skeleton materials are evenly distributed at equal distances.) Co-extrusion, two different strengths Sandwich sheets.

[0022] Choose above-mentioned a kind of sandwich sheet, intercept length 9 meters as one section, intercept 20 section sandwich sheets altogether; The longitudinal direction in each section sandwich sheet is divided into 12 equal parts, then the both sides of the...

Embodiment 2

[0024] Embodiment two: a kind of sandwich sheet material (such as figure 2 Shown) the manufacturing method and the geocell made of it.

[0025] Weave one or several materials such as steel wire, glass fiber, carbon fiber, nylon wire, PET fiber wire or flat wire, PE fishing net wire or flat wire, PP fishing net wire or flat wire into a mesh structure as the skeleton material; Recycled plastic particles from waste agricultural mulching film are used as non-skeleton materials and heated and compounded on a composite machine to form a sandwich sheet with a network distribution of skeleton materials.

[0026] Alternatively, the network framework material is coated with a PVC paste resin, and then cured in a heating oven to obtain a sandwich sheet with a network distribution of the framework material.

[0027] A geocell is made by using the above-mentioned sandwich sheets distributed in a grid shape by the method of Example 1.

Embodiment 3

[0028] Embodiment three: a kind of sandwich sheet material (such as image 3 Shown) the manufacturing method and the geocell made of it.

[0029] Steel wire, glass fiber, carbon fiber, nylon wire, PET fiber wire or flat wire, PE fishing net wire or flat wire, PP fishing net wire or flat wire, etc. are used as discrete distribution skeleton materials; one or several of these materials are first woven into The mesh is used as a skeleton material for network distribution. Different combinations of these two types of skeleton materials are combined with materials with lower melting points, such as recycled plastic particles from waste agricultural mulch films or PVC paste resin, for thermal compounding or heating and curing, etc., to obtain sandwich sheets with discrete and network-like combinations of skeleton materials.

[0030] The above-mentioned sandwich sheet composed of skeleton materials discretely and reticularly distributed is made into a geocell by the method of Embodi...

Abstract

The invention discloses a method for manufacturing a sandwich sheet and a geocell manufactured through the sandwich sheet. The sandwich sheet is formed by high-strength high-melting-point materials serving as framework materials and low-melting-point thermoplasticity materials serving as non-framework materials through co-extrusion and thermal compounding or other machining methods; the framework materials can be composed of one or multiple materials; and the non-framework materials are the same homogeneous materials. Changing of strength of the sandwich sheet is achieved by changing the variety, specification, number and different combinations of the framework materials; and the high-strength geocell can be manufactured by the high-strength sandwich sheet and high-strength corrosion-resisting U-shaped nails through a weaving method.

Description

technical field [0001] The invention relates to a manufacturing method of a sandwich sheet and a geogrid made of it. This type of material is mainly used in the field of civil engineering. As a structural material, it can be used in projects such as reinforced retaining walls, embankment reinforcement, slope protection, and soft foundation treatment; to solve local subsidence, soil lateral movement, and slope slippage Engineering problems such as displacement, soil settlement, and insufficient bearing capacity. In order to achieve the purpose of improving the construction efficiency of the project and prolonging the service life of the project. Background technique [0002] Most of the sheets currently used to make plastic geocells are extruded from a certain material formula through an extruder, and then stretched or not stretched; to change the strength of plastic geocells is only Sheets with different strengths can be obtained by changing the production formula and thic...
