Description

Strengthen grid and production mould and production method

One) technical field

The present invention relates to civil engineering and strengthen the field, especially latticed reinforcing rib and production thereof mould and production method.

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 that plane is strengthened grid, 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 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 there is the following shortcoming: when 1, grid is embedded in the soil, only have the tension of enhancing and buffer action, and sphere of action is very limited: since above only be 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; 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: geo-grid is punching on plastic sheet ability normally, and 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; 3, node is insecure: glass fiber grid particularly, at fiber bundle node in length and breadth, under complex loading conditions such as Construction of Civil Engineering and distortion, node easily comes off, thereby reinforced action is weakened greatly by the silk thread woollen yarn knitting.

Another kind of for solid type reinforcement grid, 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 can not get performance, and geotechnical grid must expend lot of materials, costs an arm and a leg.
