Description
Technical field
The present invention relates to a kind of geotechnological building materials, particularly the stable geotechnical grid of a kind of honeybee lattice.
Background technology
Geotechnical grid is a kind of purposes earth working material very widely, geotechnical grid is by the multiple layer polymer sheet band that is referred to as lattice chamber sheet, or the whole folding some layers of band, alternately connect adjacent two layers lattice chamber sheet by certain rule, the stereoscopic grid structure forming after launching, single grid sections generally has similar round, hexagon, rhombus and triangle etc., is referred to as honeybee lattice.
Geotechnical grid, then is delivered on adjacent lattice chamber sheet by this junction the stressed junction that is delivered to by lattice chamber sheet, and then makes lattice chamber entirety play side limit, reinforced action.In this process, keep the relatively stable most important of honeybee lattice shape, otherwise will cause local buckling or sedimentation, whether relatively stable junction, the lattice chamber intensity that depends on of honeybee lattice shape.
Present geotechnical grid, mainly contains two classes: first kind tradition geotechnical grid is to be welded by unstretched polymer sheet, and Equations of The Second Kind is to be formed by pegging graft, riveting by stretched polymer sheet, is referred to as unidirectional High strength geogrid.
The common shortcoming of this two classes geotechnical grid is that the junction of lattice chamber sheet is weaker.Tradition geotechnical grid is because sheet material is not stretched, and intensity is very low, and pad is not firm; Although the unidirectional High strength geogrid sheet strength of Equations of The Second Kind improves, but because method of attachment can not adopt welding after stretching, can only pass through the mechanical systems such as grafting, riveted joint connects, such connected mode does not reach junction in welding method respectively to the homogeny of intensity, can only ensure the bonding strength of a direction, it is very low that the bonding strength of its orthogonal direction detaches intensity, actual measurement detach 10% of the general not enough peel strength of intensity level (shear strength).
In engineering practice, after geotechnical grid is laid, lattice chamber sheet is subject to inhomogeneous load, while particularly circulating dynamic loading, the not stressed difference of apposition chamber sheet, if geotechnical grid junction comprehensive strength is too low, such as the very low intensity that detaches, can make geotechnical grid junction destroy, cause the effect of geotechnical grid side limit to lose efficacy, produce engineering accident; For example banket and also have the phenomenon of lattice chamber sheet lodging while rolling at geotechnical grid.
The intensity that detaches that how to improve the tensile strength of geotechnical grid, the peel strength of junction (shear strength) and junction, reaches best proportioning, makes geotechnical grid in engineering practice, bring into play maximum function, is this area engineers and technicians' research topic.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of have high bonding strength, the particularly high geotechnical grid that detaches intensity, solves the low and unidirectional High strength geogrid junction of traditional geotechnical grid intensity and detaches that intensity is low, the unmatched problem of dative chamber sheet peel strength.
For solving the problems of the technologies described above, technical scheme of the present invention is: the stable geotechnical grid of a kind of honeybee lattice, comprise the lattice chamber sheet that polymer sheet is stretched, that sheet surface, described lattice chamber is provided with is parallel to each other, equidistant along lattice chamber sheet width, dative chamber sheet width is isometric, the damping block on sheet surface, outstanding lattice chamber, the synchronous disposable lattice chamber sheet with damping block being combined as a whole with equidistant damping block that is suppressed into continuously of damping block dative chamber sheet; View picture geotechnical grid adopts sheet stacked or whole lattice chamber sheet in more than two lattice chamber folding; Whole lattice chamber sheet is folding be by the lattice chamber sheet with damping block along its length folding two-layer more than, the damping block on the sheet of adjacent two layers lattice chamber is relative between two, connects every group, forms connecting sewing, after launching, honeybee lattice are shaped as rhombus, make geotechnical grid.
Described damping block is relative between two, connects and comprises welding, bondingly or U-shaped fastens grafting every group.Described damping block protrudes from one or two surfaces of lattice chamber sheet, and the height of damping block is 0.3-40 times of lattice chamber sheet thickness, and the width of damping block is 1-100 times of lattice chamber sheet thickness.That the shape in described damping block cross section includes but not limited to is trapezoidal, square, rectangle, semicircle, semiellipse, triangle, and the shape of damping block longitudinal section outline line includes but not limited to straight line, broken line, curve.The surface of described damping block arranges decorative pattern or is light face.
The invention has the beneficial effects as follows:
1, the one, adopt stretched polymer sheet, lattice chamber sheet intensity is high, and the 2nd, sheet junction, lattice chamber is provided with damping block, and sheet junction, adjacent two layers lattice chamber damping block relatively also connects between two.Damping block method of attachment guarantees that junction is respectively to the homogeny of intensity, brings up to peel strength and equates detaching intensity, has overcome the unidirectional High strength geogrid of Equations of The Second Kind described in background technology and has detached the low-down deficiency of intensity.The connection of damping block comprises welding, bonding, and because damping block facing each other has larger contact surface, welding or bond area are large, and connecting sewing is firm, and two damping block bonding strengths are high.
2, because damping block has certain height and width, can strengthen the flexural strength of lattice chamber sheet, particularly strengthen the compressive strength of junction, lattice chamber, when constructability, roll.
3, the damping block on sheet surface, the outstanding lattice chamber of single or double impels lattice chamber entirety to play side limit, reinforced action, keeps the relatively stable of honeybee lattice shape.
4, geotechnical grid of the present invention, have before good work, construction period, work rear stability, can be applied to sidewalk, highway, railway, airport, the piece of smooth land, river course, power station, slope reinforcement greening, barricade, Hui Ba, check dam, mud-rock flow preventive works etc.Particularly because its honeybee lattice are stable, resistance to circulation dynamic load, anti-instantaneous stress is strong, controls differential settlement effective, is more suitable for earthquake-prone region engineering, road base layer, railway foundation bed floor and those and can not adopts the load bearing of existing lattice chamber.
5, geotechnical grid of the present invention, fills filler and can use soil, sand, gravel, rubble, ballast aggregate or its mixture.Particularly geotechnical grid of the present invention also can utilize those fillers that is not conventionally suitable for the load bearing application that basic unit, subbase and roadbed use, such as quarry waste, concrete waste material, regeneration asphalt, brickbat, debris from demolition and rubble, cullet, Power Plant Ash, flyash, coal ash, change iron blast furnace slag, slag, cement are manufactured slag and their mixture.
