Abstract
The utility model patent relates to a kind of double-deck anti-pressure geogrid.The vertical rib of this geo-grid and cross rib form by two-layer geo-grid overlap, be a hollow cylindrical pressure-resistent ring, be inside filled with rubber grain in the lap-joint of vertical rib and cross rib.Enhance the anti-pressure ability of grid.There is good engineer applied be worth and economic benefit, be particularly useful for side slope and retaining wall preventive works.
Description
Technical field
The utility model relates to a kind of double-deck anti-pressure geogrid, and the longitudinal and transverse rib of this double-deck anti-pressure geogrid is pair of lamina Soil test grid band, significantly can strengthen resistance to compression effect and antidetonation effect fruit of geo-grid, be specially adapted to side slope and Retaining Wall Engineering.
Background technology
Geo-grid is a kind of reinforcement material, plays reinforcing humidification in soil body engineering, and network is to be that geo-grid fully contacts with soil, increases the globality of the soil body and the intensity that meets with stresses.Current domestic widely used geo-grid, its performance and specification are substantially identical, soft and do not have rigidity, can not carry out blowing, back-up sand soil at once, and anti-pressure ability is poor.
Summary of the invention
The utility model object is to provide a kind of double-deck anti-pressure geogrid, main with in slope earth-retaining wall engineering, significantly can strengthen resistance to compression effect and antidetonation effect fruit of geo-grid.
A kind of double-deck anti-pressure geogrid, forms by falling cross rib, vertical rib and pressure-resistent ring, it is characterized in that the longitudinal and transverse rib that grid moulded by described steel forms by double-deck geo-grid band, forms double-deck anti-pressure geogrid with the pressure-resistent ring of Nodes.In use, the space between Soil test refills full sandy soil, increases the anti-pressure ability of geo-grid; Meanwhile, the rubber grain of pressure-resistent ring hollow and filling can produce enough large elasticity under pressure, has cushioning effect.
As improvement, cross rib and vertical rib form by double-deck geo-grid band, and the thickness of single Soil test is 1mm ~ 3mm, wide 25mm ~ 30mm.
As improvement, at a distance of 15mm ~ 20mm between two-layer Soil test.
As improvement, the grid size that cross rib and vertical rib form is 10mm × 10mm ~ 14mm × 14mm
As improvement, the external diameter of pressure-resistent ring is 20mm ~ 25mm, and internal diameter is 18mm ~ 22mm, and pressure-resistent ring height is 15mm ~ 20mm.
As improvement, pressure-resistent ring hollow, is inside filled with rubber grain.
The beneficial effects of the utility model are: double-deck geo-grid and pressure-resistent ring significantly enhance resistance to compression and the shock resistance of geo-grid, and structure is simple, and cost of production is low.

Detailed description of the invention
See Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of double-deck anti-pressure geogrid, be made up of double-deck cross rib 2, double-deck vertical rib 1 and pressure-resistent ring 3, it is characterized in that vertical rib 1 and the cross rib 2 of described grid are made up of two-layer geo-grid band, and be formed by connecting by pressure-resistent ring 3 in the lap-joint of vertical rib 1 and cross rib 2.In use, the space between Soil test refills full sandy soil, increases the anti-pressure ability of geo-grid; Meanwhile, the rubber grain 5 of pressure-resistent ring 3 hollow and filling can produce enough large elasticity under pressure, has cushioning effect.Double-deck anti-pressure geogrid laying step is identical with common geo-grid, and back fill course carries out mechanical ramming after exceeding vertical rib 1 or cross rib 2 height 2 ~ 3 times.
As improvement, cross rib 2 and vertical rib 1 form by double-deck geo-grid band, and the thickness of single Soil test is 1mm ~ 3mm, wide 25mm ~ 30mm.
As improvement, at a distance of 15mm ~ 20mm between two-layer Soil test.
As improvement, the grid size that cross rib and vertical rib form is 10mm × 10mm ~ 14mm × 14mm.
As improvement, the external diameter of pressure-resistent ring 3 is 20mm ~ 25mm, and internal diameter is 18mm ~ 22mm, and pressure-resistent ring 3 is highly 15mm ~ 20mm.
As improvement, pressure-resistent ring 3 hollow, is inside filled with rubber grain 5.
