Abstract
The utility model discloses a high-strength composite fiber geogrid, which is in a grid shape and formed by connecting longitudinal strips and transverse strips by means of hot melt welding according to certain longitudinal and transverse spacing. The high-strength composite fiber geogrid is characterized in that the longitudinal strips are tensile strips, the transverse strips are tensile strips or polythene strips, the width of each of the longitudinal strips and the transverse strips ranges from 1.5cm to 10cm. interlocking and meshing of reinforced bearing faces can be improved effectively, bearing capacity of a foundation is enhanced greatly, lateral shift of soil is limited effectively, and stability of the foundation is enhanced.
Description
Technical field
The utility model relates to geo-grid, is mainly used in the fields such as reinforced soft soil ground, barricade and road surface cracking resistance engineering of highway, railway, airport, harbour, dykes and dams, slag field etc.
Background technology
At present, in engineerings such as highway, railway, airport, harbour, dykes and dams, slag field, generally use geo-grid to carry out cracking resistance to reinforced soft soil ground and to barricade and road surface.Geo-grid is compared with other geosynthetics, and it has particular performances and effect.
Geo-grid is divided into the plastics geo-grid, steel is moulded geo-grid, earth grille and polyester geo-grid etc.
The plastics geo-grid is that directed simple tension or biaxial tension under heating condition again made grid-like after the polymer plate that extruding is made (raw material mostly is polypropylene or high density polyethylene (HDPE)) is gone up calking.
Earth grille is to be material with the glass fiber, adopts certain weaving to make net structure, the grid that the special coated treatment process of process forms.
The polyester fiber warp knitting geogrid is to be raw material with high-strength polyester fibers, adopts through compiling and editing to structure the grid that forms with high-intensity fiber long filament binding crosspoint.
It is with high tensile steel wire and polyethylene (PE) that steel is moulded geo-grid, and adds other auxiliary agents, makes it to become compound high-strength tension band by extruding, and, adopts and strengthens bonding interface point and the grid of moulding by certain longitudinal and transverse spacing establishment or clamping with this band.
Though above-mentioned geo-grid has superiority separately, can't satisfy the different demands of all kinds of civil engineerings.
Summary of the invention
The purpose of this utility model provides the high-strength compound fiber earthwork grid of a kind of high-modulus, low creep properties.This geo-grid comprises unidirectional tensile type and bidirectional stretch type.
A kind of high-strength compound fiber earthwork grid, be by longitudinal band and laterally band by certain longitudinal and transverse spacing sweat soldering form grid-like; It is characterized in that described longitudinal band is the tensile type band, described horizontal band is polyethylene band or tensile type band; The width of longitudinal band and horizontal band is 1.5-10cm.
Optimizing structure of above-mentioned tensile type band is to be coated with polyethylene at polyester fiber or glass fiber.
The geo-grid that horizontal band is the polyethylene band is called unidirectional tensile type.The geo-grid that horizontal band is the tensile type band is called the bidirectional stretch type.
In order to increase the frictional force with soil, described longitudinal band and laterally band or longitudinal band or laterally the Surface Machining of band be the pockmark shape.
Good effect of the present utility model is, because the tensile type band has adopted polyethylene to coat the structure of high-strength compound fiber, thereby form the directed linear structure of the macromolecule that is evenly distributed, tensile strength is big, creep properties is little, can effectively improve the interlocking, interlocking of reinforcement bearing surface, greatly the enhancing ground of degree bearing capacity, effectively retrain the lateral displacement of the soil body, strengthen the firm performance of ground.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the profile of tensile type band.
Marginal data: 1-longitudinal band, the horizontal band of 2-, 3-polyethylene layer, 4-polyester fiber.
The specific embodiment
Embodiment one: unidirectional tensile type high-strength compound fiber earthwork grid of the present utility model, be by longitudinal band 1 and laterally band 2 by certain longitudinal and transverse spacing sweat soldering form grid-like; Wherein longitudinal band 1 is the tensile type band, and the tensile type band is to be coated with the polyethylene (see figure 2) at polyester fiber 4; Laterally band 2 is polyethylene bands; The width a=1.5-10cm of longitudinal band 1 and horizontal band 2.
Embodiment two: bidirectional stretch type high-strength compound fiber earthwork cell structure of the present utility model and embodiment one are basic identical, different is that described longitudinal band 1 and horizontal band 2 all are tensile type bands, and the tensile type band is to be coated with the polyethylene (see figure 2) at polyester fiber.
In order to increase the frictional force with soil, described longitudinal band 1 and laterally band 2 or vertically bar 1 band or laterally the Surface Machining of band 2 be the pockmark shape.
The utility model tension band is not limited to that institute's act mode limits among the embodiment, and the high-strength compound tension band of any no material alterations of being done on the application basis is all within the application's protection domain.
