Abstract
The utility model relates to an earth work grid chamber on slopes, which is composed of a main part of the grid chamber and a side wall reinforcing plate, wherein the main part of the grid chamber is formed by welding a group of plastic sheets face to face, and every two plastic sheets are crossed. Honeycomb-shaped stereo grid structure is formed when the main part is stretched along a direction which is vertical to the surfaces of the plastic pieces. The side wall reinforcing plate is compounded by macromolecule sheets with one layer or multiple layers and holes and water filtering fabric, the macromolecule sheets have various colors, and connecting pieces corresponding to the main part of the grid chamber are arranged on the side wall reinforcing plate at intervals. When the utility model is used, the main part of the grid chamber is spread out, and the side wall reinforcing plate and the main part of the grid chamber are connected then. The earth work grid chamber can effectively solve the problems that when earth work grid chambers are spread out along the directions of the axial cords of the grid chambers, the capacity of the outmost sides of the grid chambers for resisting outer force is poor, filling earth of the earth work grid chambers can be carried away by the drainage process of a free face, and the earth work grid chambers have single colors. The utility model is especially suitable for reinforcing and protecting steep slopes and has strong practicability.
Description
Technical field
The utility model relates to a kind of geotechnical grid, particularly a kind of stereo grid shaped plastic geocell.
Background technology
Have three-dimensional cellular geotechnological reinforcement material and originate from the forties, the wooden and iron material of many at that time uses enters the seventies, and is along with the generally use of plane geosynthetics in developed country engineering field, more and more higher to the requirement of its engineering property; For further improving and improve the engineering property of geosynthetics, the engineer of U.S. army with the plastic sheet on plane through connecting, form three-dimensional cellular structure system, through a large amount of desert roads, the engineering test of temporary road, its engineering effort is satisfactory, and China's engineering circle is referred to as geotechnical grid.
Geotechnical grid under specific geological condition, has outstanding engineering usefulness with its unique stereochemical structure and novel engineering mechanism; In routine is used, also than conventional construction method have the more performance price than and the characteristics such as simple and easy of constructing.
No matter be natural slight slope, or the railway that manually fills, highway embankment and retaining earth dam, soil, its side slope regular meeting runs into and need make steeper side slope, and for natural slope, more spaces can be abdicated for engineering construction in the abrupt slope; For artificial slope, the earth fill amount is reduced on the abrupt slope on the one hand, can save occupation of land simultaneously.Common abrupt slope engineering need be carried out slope protection, the mode that adopts has the protection of stone-laying sheet, the flexible abrupt slope protection that the employing geosynthetics of concrete slope protection and rising in recent years is done, be that reinforcement is reinforced during the geotechnical grid on the preventive works of abrupt slope, used, the need direction that intensity is big should be perpendicular to domatic, because geotechnical grid weld bond intensity is less than sheet strength, therefore general geotechnical grid is when axis direction launches, the geotechnical grid weld bond of side ftractures easily, simultaneously domatic layer (being the free face of geotechnical grid) is being born the outer function of decorating and externally sluicing of retaining wall, and existing geotechnical grid can not meet the demands well, the applicant has applied for a utility model patent in 97 years, application number: 97221293.0, name is called: compound fabric type perforate plastic sheet geotechnical grid, this utility model is the synthetic textiles that is compounded with one deck porous at the porose frosting of forming the lattice chamber, again with the staggered in twos Face to face welding of this sheet material, when stretching, can form the boxwork structure, exist one-sided stressed big in use, make the avris solder joint that cracking phenomena be arranged, the free face of side is ornamental not strong, influences attractive in appearance.
We design a novel geotechnical grid to consider above-mentioned situation.
Summary of the invention
The utility model can provide a kind of geotechnical grid that the slope reinforces that is used for, solving geotechnical grid is applied to when domatic, the solder joint of lateral surface is because of stressed bigger, the phenomenon of easy cracking, satisfy the slope reinforce the big direction of reinforcement material intensity should vertically domatic requirement, effectively strengthen domatic layer and resist the ability of external force, and have the function of cosmetic treatment, sluicing guarantor soil.The technical solution of the utility model is:
With the stereo grid shaped geotechnical grid of existing plastic sheet as lattice chamber main part, on this basis, main body side face free face is provided with the flexible sidewall gusset plate in the lattice chamber, gusset plate dative chamber main body wall links to each other at interval, the sidewall gusset plate is various by one deck or multiple layer color, porose macromolecular sheet material is formed, or porose macromolecular sheet material and water filtering textile composition, main body corresponding connector in dative chamber is set on the sidewall gusset plate at interval, the geotechnical grid main body is general to be adopted by aspectant staggered in twos being welded of a retable tablet, when stretching with direction perpendicular to plastic cover, form a cellular stereoscopic grid structure, the sidewall gusset plate adopts split to be connected with geotechnical grid product main body, lattice chamber main body and sidewall gusset plate two parts during production for separating, during use, lattice chamber main body is linking together with the sidewall gusset plate after launching, for construction and production provide method more flexibly.
The advantage of the utility model and prior art is:
1. the retaining wall that adopts stacked geotechnical grid to form can satisfy the needs of abrupt slope preventive works.Existing geotechnical grid is applied to the abrupt slope when reinforcing, should vertically domatic requirement for satisfying the big direction of reinforcement material intensity, because geotechnical grid weld bond intensity is less than sheet strength, so the geotechnical grid need launch along the road axis direction.But domatic is that single face is stressed, and this moment, the geotechnical grid outermost point was a weld bond, and the ability of resisting external force is relatively poor.The utility model has been acquired the flexible sidewall gusset plate because of in the outside of original geotechnical grid, has effectively strengthened the intensity of the outermost point of geotechnical grid, solves former geotechnical grid side free face solder joint cracking phenomena.
2. in the stabilization works of abrupt slope, need between the geotechnical grid group water in the reinforcement layer is got rid of, therefore need form hydrophobic channel in the plate face punching of geotechnical grid product.But the drainage procedure of free face also can be taken away banketing of geotechnical grid, and the sidewall gusset plate in the utility model adopts cavernous structure water can be got rid of, and banketing of geotechnical grid can be stayed again, thereby guarantee the stable of geotechnical grid reinforcement bed course.
3. general geotechnical grid product is generally solid color, mostly be black, free face as the abrupt slope stabilization works, often needing have certain requirement to color and luster, to coordinate consistent with surrounding environment, shows the requirement that stress and environment color and luster were manufactured and can't be satisfied simultaneously to product, after increasing the sidewall gusset plate, because of lattice chamber main body and sidewall gusset plate for dividing a body structure, can make different colors according to requirement of engineering, can effectively address this problem.
Be further described below in conjunction with drawings and Examples:
