Description

A kind of ribbed lattice and application thereof

One) technical field

The present invention relates to civil engineering reinforcing rib field, especially a kind of ribbed lattice and application thereof.

Two) background technology

In civil engineering, some latticed reinforcing ribs of widespread usage, latticed reinforcing rib has two classes, one class is the plane ribbed lattice, 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, soil, stone grain are embedded, 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, transmit 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 in arbitrary deck of highway pavement and can prevent reflection crack, be laid on and be used to strengthen aspects such as tension, and reinforced earth bulkhead in the road gallet layer.

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, its effect major limitation is in the confined space up and down on plane; Even when granular material did not embed plane grid, planar the snap-in force of Chan Shenging was also very limited; 2, the loaded down with trivial details complexity of manufacturing process, the cost height: normally punching on plastic sheet of geo-grid, stretch orientation forms under heated condition again; Glass fiber grid often must be fiber bundle through weaving into net, and these complicated manufacturing process have all improved the cost of plane grid greatly.

Another kind of is the solid type ribbed lattice, 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, do not connect mutually each other, the material in the whole geotechnical grid layer is all isolated, causes the adhesion interlock action of material to can not get performance, and geotechnical grid must expend lot of materials, costs an arm and a leg.

Three) summary of the invention

The object of the present invention is to provide a kind of sphere of action big, action effect is remarkable, and manufacturing process is simple, and cost is low, and node is in conjunction with firm ribbed lattice.

The present invention seeks to realize like this: a kind of ribbed lattice is characterized in that: connect at interval discrete upright lattice tube by silk thread and become latticed.

As a kind of form of the present invention, described lattice tube can be polygon, and described lattice tube can be plastic barrel; Described lattice tube also can be circle, and described lattice tube also can be thick bamboo tube; Can also be porose on the described lattice tube sidewall; Described lattice tube can also be the stereoscopic grid tubular;

As another kind of form of the present invention, can be provided with the gelling thing in the described lattice tube; The gelling thing can be cement concrete in the described lattice tube.Can be provided with thin layer or clathrum under the grid silk thread between the described ribbed lattice lattice tube.

As a kind of application of ribbed lattice of the present invention, this ribbed lattice can be applicable to the civil engineering reinforcement, promptly be layed in the civil engineering soil body or other materials in or on the interface, to improve the soil body or structure intensity and non-deformability.

Another kind as ribbed lattice of the present invention is used, this ribbed lattice is applied in the hydraulic engineering as the ballast grid of making the interlock block soft fascine mattress, in ballast grid lattice tube, can insert rubble or insert cement concrete, can constitute the interlock block soft fascine mattress with the flexible cloth under the ballast grid, this ballast grid can be arranged at earlier on the soft raft, in the lattice tube, insert stone or casting cement concrete again, can save heavy carrying like this, raise the efficiency and quality.

Another kind as ribbed lattice of the present invention is used, this ribbed lattice can be used as a connection clump of piles and is applied to the ground processing, its process can be: set into each single pile body outer wall lattice tube underground earlier, when in the lattice tube, pouring into the gelling thing again to nearly top, connect each pile body with described silk thread by the through wires hole on the pile body outer wall lattice tube and become latticed, again lattice tube top end is filled up.

Owing to adopt above-mentioned ribbed lattice, when ribbed lattice 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 lattice tube, owing to be full of by the granular material of reinforcement or non-particulate material between the at interval discrete upright lattice tube, what thereby the power on the block again can be three-dimensional is delivered to by on the material of reinforcement, so not only overcome the plane grid interlocking and transmitted stress only in the defective of the confined space of planar range, and overcome the defective that the adhesion interlock action that is reinforced material layer that geotechnical grid causes can not get bringing into play, and the ability of this ribbed lattice interlocking particle or transmission stress is strengthened greatly, sphere of action increases in the space up and down of ribbed lattice greatly, and the soil body or structure intensity and non-deformability improve greatly; And the saving material, ribbed lattice manufacturing process of the present invention in addition is simple, cheap.

Below in conjunction with the drawings and specific embodiments ribbed lattice of the present invention and application thereof are described further.
