One) technical field

The utility model relates to a kind of civil engineering and uses the lattice chamber.

Two) background technology

The lattice chamber is a kind of cellular stereoscopic grid structure, the lattice chamber is used more and more general in civil engineering protection, ground are handled, the geotechnical grid of prior art is a kind of of lattice chamber, geotechnical grid is the cellular stereoscopic grid structure of being made by macromolecular material, and the lattice chamber is meant the stereoscopic grid structure of being made by various materials, each lattice band of the lattice chamber of prior art is identical with the lattice band height h of other lattice chambers, each lattice band height h also is identical on this lattice strip length L direction, the lattice chamber of prior art is the equal altitudes type, as shown in Figure 1 and Figure 2.

This lattice chamber is when being used for reinforcement, and have following shortcoming: 1, distribution of material is unreasonable, causes lattice chamber waste of material: do not distinguish the difference in following main stress district of outer lotus effect and non-main stress district, cause the lattice chamber waste of material in non-main stress district; When increasing its enhancing reinforced action, no matter in the main stress district or in non-main stress district, the lattice chamber of prior art all is the lattice band height that increase whole lattice chamber, causes further waste of material; 2, discontinuous and cause stressed unreasonable between the deck of handling by the lattice chamber: especially when the foundation material below the indoor institute of lattice underfill material is different from the lattice chamber, perpendicular to lattice chamber lattice band short transverse with bonding surface ground be smooth plane, lattice chamber floor is connected defective tightness with ground, can not make the two-layer continuous state that is in, cause stressed unreasonable; 3, can not bring into play the adhesion interlock action that is reinforced material: because each lattice band of the formation lattice chamber of prior art is contour, it is indoor at each isolated lattice to be reinforced dispersion of materials, adhesion interlock action between the material is destroyed fully, thereby makes the due intensity of material itself can not get performance; 4, easily cause appearance interruption slippage between lattice chamber interlayer and other decks; When being especially in use in the slope protection, though equal altitudes type lattice chamber makes water erosion, the landslide of lattice chamber surface obtain stoping, but because each lattice band height of lattice chamber all is equal to, perpendicular to the lattice band is short transverse be and domatic parallel burnishing surface type with domatic bonding surface, like this under the effect of undercurrent, easily form whole slide plane, and will cause the failure of slope protection in the geotechnical grid bottom;

Three), utility model content

The purpose of this utility model is to provide a kind of stressed lattice chamber material, lattice chamber floor and compact Reinforced grid of substructure material of rationally, effectively utilizing.

The purpose of this utility model is achieved like this: a kind of Reinforced grid is the stereoscopic grid structure with a plurality of little lattice chamber that is made of vertical horizontal lattice belt, and it is characterized in that: the lattice band of this lattice chamber of described formation is not contour.

Described lattice band both can be the lattice band that constitutes each little lattice chamber of lattice chamber, also can be the vertical lattice band or the horizontal lattice band of a plurality of little lattice of the formation chamber of lattice chamber.

As a kind of form of the present utility model, each lattice band height of described formation Reinforced grid is identical on himself length direction, and has at least one grid band height and other lattice band height not to wait.

As another kind of form of the present utility model, there is at least one lattice band height on its length direction, to be not contour type in the lattice band of described formation Reinforced grid.

As another kind of form of the present utility model, vertical lattice band of described formation Reinforced grid and horizontal lattice band are in that each little lattice is indoor and present the lattice band that at least one side is a spill.

As another kind of form of the present utility model, vertical lattice band of described formation Reinforced grid and horizontal lattice band are in that each little lattice is indoor and present the lattice band that at least one side is a convex.

As another kind of form of the present utility model, in the not contour lattice band of described formation Reinforced grid, have that not contour lattice band height is corresponding with other not contour lattice band height not to be waited at least.

As another kind of form of the present utility model, the limit portion of described formation Reinforced grid is combined with the plane grid.

As another kind of form of the present utility model, the lattice band of described formation Reinforced grid both can also can be grid for plate.Described plate both can be that plastics are made, and also can be the lattice band that steel plate is made, and can also be the tabular lattice band that steel wire grid covers plastic layer outward; Described grid can be the latticed lattice band that steel wire grid or plastic grid constitute.

The utility model compared with prior art has the following advantages: because Reinforced grid lattice band height does not wait, perhaps on whole lattice strip length direction, be degree of uprising shape, like this perpendicular to Reinforced grid lattice band short transverse with ground or domatic bonding surface be non-burnishing surface type, main stress district lattice band height is increased and make stressed rationally, and can rationally utilize material, can make again on the other hand on the Reinforced grid dative chamber or under the deck contact be in continuous state, skid resistance is strengthened greatly, and also makes by the adhesion interlock action of reinforcement material and strengthened greatly.
