Abstract
The utility model discloses a plastic earthwork grid chamber which is composed of bar-shaped plastic earthwork grid chamber material sheets after uniaxially stretching and connecting clamps. The connecting clamps have a double-side structure, and one end of each connecting clamp is connected with each other. One side of each connecting clamp is provided with a connecting hole, and the other side is provided with a positioning plug. Every two grid chamber material sheets in one group are placed crisscross, connection parts of the grid chamber material sheets are clamped by the connecting clamps, and positioning plugs are inserted into the connecting holes to fix the grid chamber material sheets, and then the connecting parts are welded. Thus, the grid chamber material sheets are connected together. When a group of bar-shaped plastic grid chamber material sheets connected well is expanded vertically along the vertical direction of the material sheets, a latticed solid grid chamber is formed. Because the stretched material sheets are used as the grid chamber material sheets, the rigidity and the creep resisting performance of the existing earthwork grid chamber is greatly enhanced. The utility model has the advantages that simple manufacture technique, less investment, low cost of raw materials, raw material saving, and high strength. The plastic earthwork grid chamber which is composed of a plurality of grid chamber material sheets in longitudinal connection has draining function because the gaps existing among the material sheets can serve as drainage gaps, and can manufacture super-high earthwork grid chamber material sheets, according to the requirement.
Description
Technical field: the utility model belongs to the geosynthetics technical field, is specifically related to a kind of plastic geocell.
Background technology: use three-dimensional Cellular Networks investigate things wooden and made of iron to be applied to engineering foundation and originate from the forties, enter after the middle nineteen seventies, macromolecule geotechnique material rises gradually, handle aspects such as bank protection, desert highway, wharf, airport construction, port and harbour construction in hag matter engineering and carried out a large amount of engineering tests, using this kind material in geotechnical engineering circle at present is the novel geosynthetics that rises rapidly behind geotextiles and plane grid.In recent years, the geotechnical grid that existing plastic sheet welding is made, the utility model patent of the applicant's application in 97 years, " compound fabric type perforate plastic sheet geotechnical grid " patent No.: 97221293, this geotechnical grid is formed the boxwork structure by plastic sheet, compound layer of non-woven fabric on the plastics slip, it can prevent flowing of institute's underfill material, has strengthened the stability of institute's underfill material.
General geotechnical grid is to extrude lattice chamber sheet material with macromolecule raw material at present, cut, form through ultrasonic bonding then, the performance of its product has different Practical Performances with raw material and processing method different, but any product all has the limitation of its use, prove by engineering experiment, traditional geotechnical grid is when handling deep layer soft soil foundation, show as the rigidity deficiency, creep-resistant property is poor, shortcomings such as the raw material use amount is many are difficult to make the geotechnical grid of wide yardstick, have restricted the scope of its application, we design a novel geotechnical grid to consider above-mentioned reason, to remedy the deficiency of existing geotechnical grid.
Summary of the invention: a kind of plastic geocell that the utility model provides, form with being connected to press from both sides by the bar plastic lattice chamber sheet material after the simple tension, connect folder and be bilateral structure, one end links together, one side is provided with connecting hole, another side is to there being pilot pin, one group of lattice chamber sheet material is staggeredly placed in twos, with connecting the connecting portion of clamping lattice chamber sheet material, pilot pin inserted in the connecting hole be welded to connect the position behind the sheet material of fixed grating chamber, so just lattice chamber sheet material is coupled together, one group of bar plastic lattice chamber sheet material that connects when lattice chamber sheet material vertical direction is launched, is formed latticed three-dimensional lattice chamber.
Lattice chamber sheet material is a high molecule plastic lattice chamber sheet material, the length and width of lattice chamber sheet material, thick can the selection as required, general single lattice chamber sheet material length is 1～6 meter, highly be 0.01～0.3 meter, thickness is 0.01～0.05 meter, can add modifier such as antioxidant, light stabilizer, the preferred high density poly propylene of lattice chamber sheet material, polythene material in the sheet material of lattice chamber.
Can be according to the requirement of product, the geotechnical grid of design different size, in order to increase the sluicing function of geotechnical grid, available connection folder vertically connects several lattice chamber sheet materials, increase the height of lattice chamber, can reserve the slit of different in width between the sheet material of lattice chamber as required, as the seam that sluices, generally between 1 centimetre-4 centimetres, optimum value is at 3.5 centimetres as the lattice chamber sheet width of sluicing type geotechnical grid.
Because of selecting for use along its length lattice chamber sheet material after stretching as lattice chamber sheet material, and with connecting clamping back welding surely, can improve the rigidity and the creep-resistant property of existing geotechnical grid greatly, it is simple to have production technology, small investment, do not increase the cost of raw material, raw material have been saved, increased intensity, sluicing plastic geotechnical grid when combining with a plurality of (generally using 2-10) lattice chamber sheet material owing to there is the seam that sluices between the sheet material of lattice chamber, has had the sluicing function again, and the height of lattice chamber can vertically be formed by connecting by a plurality of sheet materials as required, has overcome the restriction that single sheet material is made height.

The specific embodiment: below in conjunction with accompanying drawing the utility model is described further, but the utility model is not limited thereto.
Embodiment 1
As Fig. 2, Fig. 3, shown in Figure 4, plastic geocell by add antioxidant and light stabilizer and simple tension along its length after bar shaped high density polyethylene (HDPE) lattice chamber sheet material 1 and form with the connecting pin 2 of material, 4 meters of the length of lattice chamber sheet material 1, wide 0.15 meter, thick 0.002 meter, one group of lattice chamber sheet material is staggeredly placed in twos, clamp the connecting portion of lattice chamber sheet material with connecting folder 2, to be welded to connect the position behind the sheet materials of fixed grating chamber in the pilot pin 5 insertion connecting holes 4, so just lattice chamber sheet material is coupled together, one group of bar plastic lattice chamber sheet material that connects when lattice chamber sheet material vertical direction is launched, is formed latticed three-dimensional lattice chamber, as shown in Figure 1.
As shown in Figure 5, lattice chamber sheet material by add antioxidant and light stabilizer and simple tension along its length after bar shaped high density poly propylene lattice chamber sheet material 1 and form with the connecting pin 2 of material, lattice chamber sheet material Fig. 5, connection folder shown in Figure 6 vertically couples together lattice chamber sheet material, can form superelevation lattice chamber like this, slit between the lattice chamber sheet material 1 is promptly as the seam 3 that sluices, gap width is 0.01 meter, connect the same material of folder dative chamber sheet material, the width that connects folder 2 is 0.02 meter, so just lattice chamber sheet material is coupled together, one group of bar plastic lattice chamber sheet material that connects when lattice chamber sheet material vertical direction is launched, is formed latticed three-dimensional lattice chamber.
One group of geotechnical grid product main body that will connect during use is launched along axis direction, and then the suitable as required filler compactings such as sand, soil or rubble of filling out get final product.
