However, it has been found that such three-dimensional geotextile mats are too loose and soft, have insufficient tensile strength, and are prone to collapse, deform and break after being washed by flood or heavy rain, thus damaging vegetation and soil filled therein. Therefore, in view of the above situation, it is necessary to develop a geotechnical pad with stable structure to overcome the disadvantages of the current practical application.

Detailed Description

The invention will now be further described with reference to the accompanying drawings, in which:

the first embodiment is as follows:

please refer to fig. 1, a novel composite geotechnical pad, comprising a plastic wire mesh 13 and a cloth layer 14, wherein the plastic wire mesh 13 is laid above the cloth layer 14, the novel composite geotechnical pad further comprises a vertical grid layer 11 and a reinforcement layer 12, the vertical grid layer 11 is provided with three-dimensional grids which are continuously arranged and distributed, the three-dimensional grids are in a hexagonal honeycomb structure and are arranged in a hollow manner, the reinforcement layer 12 is provided with a plurality of ribs, the ribs are mutually connected in a staggered manner to form a planar mesh structure, the vertical grid layer 11 and the reinforcement layer 12 are arranged on the top surface of the plastic wire mesh 13, and the vertical grid layer 11 and the reinforcement layer 12 are integrally formed.

Based on the principle that the hexagonal structure can obtain the maximum utilization space by using the least materials, and the hexagonal structure is higher in relative stability, the composite geotechnical pad adopts the hexagonal honeycomb structure, so that the materials are saved, and the production cost is reduced; meanwhile, the structural stability is kept, the bearing capacity of the geotechnical mat is higher, the geotechnical mat is not easy to collapse and deform after being subjected to the action of external force, the soil storage and the vegetation are more durable, and the rapid rooting growth of the vegetation is facilitated.

The reinforcing rib layer 12 is used for reinforcing the vertical grid layer 11 stably, so that the strength and the firmness of the vertical grid layer 11 are further improved, and the vertical grid layer 11 is prevented from being broken and the three-dimensional grids are prevented from collapsing. In the embodiment, the vertical grid layer 11 and the reinforcement layer 12 are made of polypropylene and are formed by hot melting and integral molding through an injection mold. The polypropylene has the advantages of no toxicity, corrosion resistance, high toughness, high wear resistance and the like.

Elastic fibers 23 are arranged on one surface, close to the plastic silk screen 13, of the reinforced layer 12, and the elastic fibers 23 are in a barbed shape and distributed on the whole surface. The hook-thorn-shaped elastic fibers 23 are used for being connected with the bottom layer plastic wire mesh 13, and the plastic wire mesh 13 is provided with irregular pores, so that the reinforced layer 12 can be adhered to the plastic wire mesh 13 through the elastic fibers 23, the integral assembly of the composite geotechnical pad is facilitated, the integral adhering effect is firm, and the separation is not easy. In this embodiment, the elastic fiber 23 is made of nylon. The nylon is not easy to burn and belongs to an environment-friendly material.

The plastic wire net 13 is used for draining water and enabling the vegetation rhizome to penetrate through the fine hole and be firmly combined with the vegetation rhizome, so that the rooting growth of the vegetation is facilitated.

The cloth layer 14 is used for protecting sediment at the bottom and preventing the sediment from being washed and eroded by flood or rainwater. In this embodiment, the fabric layer 14 is a non-woven fabric, and the non-woven fabric is made of polypropylene staple fibers.

In order to ensure that the three-dimensional grid has enough space to enable vegetation to grow and avoid the phenomenon that soil, gravels and stones are easily washed and lost due to overlarge space, the aperture of the three-dimensional grid is E, and E is more than or equal to 5mm and less than or equal to 20 mm.

Example two:

referring to fig. 2, the difference between the first embodiment and the second embodiment is that a pin 22 is disposed at a node connected to the ribs of the rib-adding layer 12, and the direction of the pin 22 is consistent and downward. The pin 22 and the reinforced layer 12 are integrally formed, and the pin 22 is used for connecting the plastic wire mesh 13 and the cloth layer 14, so that the composite geotechnical pad is integrally fixed on the surface of soil or a slope. In addition, because the pins 22 and the reinforced layer 12 are integrally formed, the use of additional connecting pieces is reduced, and the material cost is reduced.
