Description
Technical field
The present invention relates to a kind of geotechnological building materials, the geotechnical grid that particularly a kind of honeybee lattice are stable.
Background technology
Geotechnical grid is a kind of purposes earth working material widely, geotechnical grid is by the multiple layer polymer sheet band being referred to as lattice room sheet, or the whole folding some layer of band, alternately adjacent two layers lattice room sheet is connected by certain rule, the spatial lattice structure formed after launching, single grid sections generally has similar round, hexagon, rhombus and triangle etc., is referred to as honeybee lattice.
Geotechnical grid is delivered to junction by lattice room sheet by stressed, then is delivered on adjacent lattice room sheet by this junction, and then makes lattice room entirety play side limit, reinforced action.Keep the relatively stable most important of honeybee lattice shape in the process, otherwise will cause local buckling or sedimentation, whether honeybee lattice shape is relatively stable depends on junction, lattice room intensity.
Present geotechnical grid, mainly contains two classes: first kind tradition geotechnical grid is welded by unstretched polymer sheet, and Equations of The Second Kind is formed by grafting, riveted joint by stretched polymer sheet, is referred to as unidirectional High strength geogrid.
The common drawback of this two classes geotechnical grid is that the junction of lattice room sheet is weaker.Tradition geotechnical grid is because sheet material is without stretching, and intensity is very low, and pad loosely; 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 be connected by the mechanical system such as grafting, riveted joint, such connected mode does not reach junction in welding method respectively to the homogeny of intensity, the bonding strength in a direction can only be ensured, it is very low that namely the bonding strength of its orthogonal direction detaches intensity, actual measurement detach 10% of the general not enough peel strength (shear strength) of intensity level.
In engineering practice, after geotechnical grid is laid, when lattice room sheet is subject to uneven load, particularly circulation dynamic loading, the not stressed difference of apposition room sheet, if geotechnical grid junction comprehensive strength is too low, such as very lowly detach intensity, geotechnical grid junction can be made to destroy, cause the limit effect of geotechnical grid side to lose efficacy, produce engineering accident; The phenomenon of lattice room sheet lodging is such as also there is when geotechnical grid bankets and rolls.
How to improve the tensile strength of geotechnical grid, the peel strength (shear strength) of junction and junction detach intensity, reaching optimum proportioning, make geotechnical grid play maximum function in engineering practice, is the research topic of this area engineers and technicians.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly has high bonding strength, the particularly high geotechnical grid detaching 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 room sheet peel strength.
For solving the problems of the technologies described above, technical scheme of the present invention is: the geotechnical grid that a kind of honeybee lattice are stable, comprise the lattice room sheet that polymer sheet is stretched, described lattice room sheet surface be provided with parallel to each other, equidistant along lattice room sheet width, dative room sheet width is isometric, the damping block on outstanding sheet surface, lattice room, the synchronous disposable lattice room sheet being suppressed into the band damping block be combined as a whole with equidistant damping block continuously of damping block dative room sheet; View picture geotechnical grid adopts sheet stacked or whole lattice room sheet in two panels above lattice room to fold; Whole lattice room sheet fold be by the lattice room sheet of band damping block along its length folding two-layer more than, the damping block on the sheet of adjacent two layers lattice room is relative between two, connects every group, forms connecting sewing, and after launching, honeybee lattice shape is rhombus, makes geotechnical grid.
Described damping block is relative between two, comprises welding every group connection, bondingly or U-shaped fastens grafting.Described damping block protrudes from one or two surfaces of lattice room sheet, and the height of damping block is 0.3-40 times of lattice room sheet thickness, and the width of damping block is 1-100 times of lattice room sheet thickness.The shape in described damping block cross section includes but not limited to 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, one is adopt stretched polymer sheet, and lattice room sheet intensity is high, and two is that sheet junction, lattice room is provided with damping block, and sheet junction, adjacent two layers lattice room damping block between two relatively and connect.Damping block method of attachment guarantees junction respectively to the homogeny of intensity, brings up to detach intensity equal with peel strength, overcomes the unidirectional High strength geogrid of Equations of The Second Kind described in background technology and detaches the low-down deficiency of intensity.The connection of damping block comprises welding, bonding, because damping block facing each other has larger contact surface, welding or bond area large, connecting sewing is firm, and two damping block bonding strengths are high.
2, because damping block has certain height and width, the flexural strength of lattice room sheet can be strengthened, particularly strengthen the compressive strength of junction, lattice room, roll during constructability.
3, lattice room entirety of impelling the damping block that single or double gives prominence to sheet surface, lattice room plays side limit, reinforced action, keeps the relatively stable of honeybee lattice shape.
4, geotechnical grid of the present invention, before there is good work, construction period, work rear stability, 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. can be applied to.Particularly because its honeybee lattice are stablized, resistance to circulation dynamic load, anti-instantaneous stress is strong, control differential settlement effective, be more suitable for earthquake-prone region engineering, road base layer, railway foundation bed floor and those can not adopt the load bearing of existing lattice room.
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 not usually to be suitable for the filler of load bearing application of basic unit, subbase and roadbed, and 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 manufacture slag and their mixture.
