Abstract
The invention discloses a method for manufacturing hot-melt integral geocells, which comprises the following steps: parallelly arranging strip polymer plates, wherein a node is arranged between two adjacent plates, the nodes between the plates in each layer are arranged in a staggered mode, and the position of the node is provided with a through hole; then, carrying out melt injection processing on the nodes, wherein an injected molten material passes through the through holes, and forms connecting blocks around the through holes, so that two adjacent plates are connected together; and finally, carrying out transverse drawing on the plates subjected to superimposition and melt injection processing so as to draw each strip polymer plate into a waved polymer plate, and carrying out butt jointing on the waved polymer plates at the nodes so as to form a 8-shaped geocell. According to the invention, through connecting adjacent plates together by way of melt injection, a high-node-strength integral geocell is formed, and the integral geocell is higher in node strength, plate strength and production efficiency, therefore, the integral geocell is an ideal substitute product of current common geocells.
Description
Technical field
The present invention relates to a kind of hot melten type monolithic devices geotechnical grid and preparation method thereof.Said material is mainly used in the civil engineering construction, as using in the engineerings such as structural material side slope protection, reinforced earth bulkhead, dykes and dams, subgrade processing; To solve domatic slippage, local collapse, the hypodynamic phenomenon of carrying.
Background technology
Geotechnical grid is indispensable in the current capital construction as a kind of novel civil engineering structure material.Its node structure form of present product and preparation method thereof is a lot; Generally all be that common extrusion board cuts into ribbon; Adopt ultrasonic welding machine to weld together node; Such geotechnical grid node intensity is very low, has only tens newton, is about 1/10th of the own intensity of material; The geotechnical grid that also has is the sheet material that adopts simple tension, and the punching back is fixed with metallic screw, and the node intensity of this product is very high; But metal gets rusty easily, and production efficiency is very low, and cost is very high; And sheet material is because simple tension; Sheet material is longitudinally torn easily and is caused the engineering failure, also is difficult to realize suitability for industrialized production, does not have real practical value; The geotechnical grid that also has adopts plug-in unit to fix node, and this product node is easy to slippage, does not have the fixedly effect of the soil body.
Summary of the invention
The object of the invention provides a kind of hot melten type monolithic devices geotechnical grid and preparation method thereof with regard to being to be directed against the defective of above-mentioned prior art, and it is as a whole that the node of the geotechnical grid that the present invention processes and base material sheet material are fused into, and both improved node intensity,
Can realize high strength through the sheet material that adopts unlike material again, also be easy to suitability for industrialized production, enable large tracts of land and promote the use of.
Its technical solution is following: a kind of preparation method of hot melten type monolithic devices geotechnical grid, and it is that the strip polymer plate is arranged side by side, has node between adjacent sheet metal; Node between every laminate material is crisscross arranged and gets through the hole at node location; Then node is carried out melt injection and handle, the melted material of injection passes through these holes, and around the hole, forms contiguous block; Adjacent two sheet materials are linked together; With sheet material cross directional stretch superimposed and that handle through melt injection, every strip polymer plate is drawn into waveform at last, and butt joint forms 8 font geotechnical grids to the waveform polymer plate at the node place.
Above-mentioned sheet material can be polymer such as polyethylene, polypropylene, also can be the composites of these polymer through high-strength materials formation such as interpolation glass, carbon fibres, also can be high-strength panel or the sheet materials that these polymer form through biaxial tensiones.
The shape of above-mentioned punching can be various geometries such as circular, square, comes finally to confirm with material property according to actual needs, makes the hole laterally be evenly distributed on sheet material.
The used material of melt injection is with the sheet material identical materials or with sheet material the non-same material of compatibility to be arranged.
length of both sides contiguous block is not more than the width of sheet material band, thickness generally between 0.5-5mm, the cylinder that the aperture melt injection on contiguous block and the sheet material band forms.
The present invention links together adjacent sheet metal through the melt injection mode, forms the monolithic devices geotechnical grid of high node intensity, has higher node intensity, higher timber intensity, higher production efficiency, is the desirable substitute products of current common geotechnical grid.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
The present invention is earlier with 1, the 2 superimposed placements of two strip polymer plates; And the punching 4 at node 3 places, then node 3 being carried out melt injection and handle, the melted material of injection is through these holes; And around the hole, form contiguous block 5; Superimposed successively more afterwards other strip polymer plates also carry out melt injection to the node place to be handled, and the node between every laminate material is crisscross arranged, at last will be superimposed and through the sheet material cross directional stretch of melt injection processing; Every strip polymer plate is drawn into waveform, and butt joint forms 8 font geotechnical grids to the waveform polymer plate at the node place.
OnState the waveform polymer plate that the whole geotechnical grid of hot melten type comprises adjacency, the node place of adjacent polymeric thing sheet material joint offers through hole, and melted material passes through these holes, and around the hole, forms contiguous block.
Above-mentioned sheet material can be polymer such as polyethylene, polypropylene, also can be the composites of these polymer through high-strength materials formation such as interpolation glass, carbon fibres, also can be high-strength panel or the sheet materials that these polymer form through biaxial tensiones.
The shape of above-mentioned punching can be various geometries such as circular, square, comes finally to confirm with material property according to actual needs, makes the hole laterally be evenly distributed on sheet material.
The used material of melt injection is with the sheet material identical materials or with sheet material the non-same material of compatibility to be arranged.
The length of above-mentioned contiguous block is not more than the width of sheet material band, thickness generally between 0.5-5mm, the cylinder that the aperture melt injection on contiguous block and the sheet material band forms.
Above-mentioned sheet material strip width can be 50mm, thickness 1mm, and the aperture 3mm that is beaten, pitch of holes 15mm, hole array pitch 200mm, contiguous block thickness 1mm is through becoming the hot melten type monolithic devices geotechnical grid of high node intensity as shown in Figure 1 behind the melt injection.
