Description

The reinforcement net

One) technical field

The utility model relates to civil engineering reinforcement field, especially netted reinforcement body.

Two) background technology

At present, in civil engineering, some latticed reinforcing ribs of widespread usage, latticed reinforcing rib has two classes, and a class is the plane Reinforcement gridiron, as shown in Figure 1, as unidirectional geo-grid, two-way geo-grid, glass fiber grid etc., these grids have bigger eyelet and high strength and stiffness, and soil, stone grain are embedded, and produce snap-in force with soil or stone grain, thereby can spread the stress in soil or the stone grain, the displacement of restriction soil or stone grain is transmitted stress, the effect of reinforcing material tensile strength and isolation.For example as: be laid on the side slope firm side slope and can afforest, be laid on and form operation platform on the soft base wad layer and isolate tensile layer, being laid on end of the bridge bankets and strengthens the stretching resistance of banketing and prevent differential settlement, be laid on and can strengthen stretching resistance in arbitrary deck of highway pavement and prevent reflection crack, and aspect such as reinforced earth bulkhead.

Though above plane grid can play above effect, but have the following shortcoming: 1, sphere of action is very limited: because above only for the plane grid, only planar produce snap-in force with soil or stone grain, to such an extent as to make the stress in diffusion soil or the stone grain, the equal major limitation of effect such as the displacement of restriction soil or stone grain are in the confined space up and down on plane, and active force is little; Even when granular material did not embed plane grid, planar the snap-in force of Chan Shenging was more limited.

Another kind of is the solid type Reinforcement gridiron, as geotechnical grid, as shown in Figure 2.The shortcoming of geotechnical grid is that the material that will strengthen has been isolated in each little lattice is indoor, does not connect mutually each other, and the adhesion interlock action of the material that each lattice chamber and another lattice are indoor obtains destroying, and geotechnical grid must expend lot of materials, costs an arm and a leg.

Three) utility model content

The purpose of this utility model is to provide a kind of sphere of action big, makes full use of by the adhesion interlock action of reinforcement material, and manufacturing process is simple, the reinforcement net that cost is low.

The utility model purpose is achieved like this: be used for the reinforcement net that civil engineering improves the soil body or structure intensity and non-deformability, include grid, it is characterized in that: also include at interval discrete block, described grid covers and connects the discrete block in described interval and the matrix knot is arranged between at interval discrete block.

As a kind of form of the present utility model, described block at interval Discrete Distribution and has the matrix node of two-layer grid coverage combination between at interval discrete block between two-grid.

As another kind of form of the present utility model, between the described two-grid plane grid can also be arranged, block interval Discrete Distribution is in the checkerwork cell of this plane grid.

As another kind of form of the present utility model, described block can disperse at interval and be embedded in the checkerwork cell of a plane grid, another grid covers on this plane grid and the at interval discrete block, and between at interval discrete block the matrix node that combines with plane grid of grid coverage to some extent.

As another kind of form of the present utility model, Discrete Distribution is on thin film at interval for described block, and described grid covers on this discrete at interval block, and the matrix knot that has grid to combine with film between block; Described film edge can also be extended with the grid that coats at interval discrete block.

As another kind of form of the present utility model, described block both can also can be the cement concrete piece for stone.

As another kind of form of the present utility model, the edge of described reinforcement net can be provided with the plane grid.

Owing to adopt above-mentioned reinforcement net; when the reinforcement net is arranged in granular material or the non-particulate material; when being subjected to tensile stress or shear stress; power on the grid can be delivered on the block; owing to be full of granular material or the non-particulate material that is reinforced between the at interval discrete block; what thereby the power on the block again can be three-dimensional is delivered on the material that is reinforced; so not only overcome the plane grid interlocking and transmitted stress only in the confined space and the little defective of power transmission effect of planar range; and overcome the defective that the adhesion interlock action that is reinforced material that geotechnical grid causes can not get bringing into play; block in the reinforcement net of the present utility model can with produced better adhesion stress and interlock action by reinforcement material; thereby the ability of this reinforcement net interlocking particle or transmission stress is strengthened greatly; sphere of action is increased in the space up and down of reinforcement net greatly; and reinforcement net manufacturing process of the present utility model is simple, cheap.

Below in conjunction with the drawings and specific embodiments the utility model reinforcement net is described further.
