Abstract

The utility model relates to an anti-crack grid sheet for the reinforcement of roads. The utility model adopts a plastic grid sheet made of polymer material. The utility model can be arranged at the surfaces of roads, railways, road bases of roads, ground bases of buildings, etc. The grid structure of the utility model is favorable for the tight combination of material arrangement. The strength of a structure layer is enhanced, and the bearing ability of the structure layer is raised. When using on the surfaces of roads, the utility model can effectively prevent or reduce the phenomena of cracking of the surface layers of the roads, reflection characterized cracking and tire tracks on the surface layers. When using on the road bases and the ground bases, the utility model can prevent the phenomena of splits.

Description

Anticrack grid sheet for reinforcement of pavement

The utility model is a kind of pavement strengthening anticracking net sheet.Be mainly used in the whole compactness of strengthening road surfacing material.It can be applied to highway pavement, railway bed, highway subgrade, structure foundation etc. and locate.

In the field of building the road, be full of cracks and reflective crack ubiquity take place in highway pavement, even newly-built highway above-mentioned crack will occur less than 2 years formally being open to traffic, and defective such as sagging, uneven, the rut on road surface also often has generation, this all is because auxilliaryly establish the globality of material and intensity is relatively poor causes.Up to now, in prior art, yet there are no the good way that addresses the above problem.

The purpose of this utility model provides a kind of pavement strengthening anticracking net sheet, to strengthen the whole compactness of paver, improves the supporting capacity on road surface.

Solution of the present utility model is as follows: adopt polymeric material to make plastic deeping, the mesh length of net sheet is 50-60mm, and the mesh width of net sheet is 40-50mm, and mesh horizontal bar width is 4-6mm, the vertical muscle width of mesh is 4-6m, and net muscle thickness is 2-4mm.

Because net sheet itself adopts polymeric material, it have corrosion-resistant, high temperature resistant, tensile strength is high, the tension rigidity is big, the advantage of anti-song and good endurance.Therefore, be difficult for being damaged when it is applied in the paver, simultaneously, its net structure helps combining closely of paver, makes the total layer form overall structure, and has strengthened the intensity of deck.When deck was stressed, its horizontal force can high-speed transfer be given the net sheet, and its surperficial pressure can spread rapidly, has reduced deck impaired possibility when stressed effectively.

In the roadbed of Home Network sheet adding highway, railway or the ground of building, can improve the supporting capacity of roadbed or ground, prevent that the crack from producing.The Home Network sheet adds highway pavement, promptly join in the bituminous concrete paver on the semi-rigid type base, can improve the supporting capacity of supercrust, prevent or reduce the generation of road surface crack, reflective crack and road surface rutting effectively, prolonged more than three times the application life on road surface, reduced maintenance of surface and maintenance cost; Owing to the reinforcement of pavement strength, also can reduce the thickness of road surfacing simultaneously, save road surfacing material.

Describe in detail according to embodiment below.

Fig. 1, embodiment Facad structure figure.

Fig. 2, the A-A profile of Fig. 1.

Fig. 3, user mode figure.

Referring to Fig. 1, the mesh length of net sheet 4 is 54mm, and its mesh width is 46mm, and the width of the vertical muscle 5 of mesh is 6mm, and the width of mesh horizontal bar 6 is 4mm, and mesh horizontal bar 6 is circular arc.

Referring to Fig. 2, the thickness of mesh horizontal bar 6 is 4mm, and the thickness of the vertical muscle 5 of mesh is 2mm, and on net muscle thickness direction, vertical muscle is positioned at the horizontal bar middle part, respectively reserves 1mm up and down.

Referring to Fig. 1, the direction of mesh horizontal bar circular arc projection is the positive direction of net sheet again.During laying, the positive direction of net sheet is identical with direction of traffic.To lay highway is example, and referring to Fig. 3,1 is the asphalt concrete pavement layer, and 2 is ash bed, and 3 is the stone layer, 5 roadbeds for compacting, and net sheet 4 is laid on the ash bed.The instantaneous longitudinal impact force that the arc-shaped structure of above-mentioned mesh horizontal bar can make horizontal bar be subjected to is distributed to all the other each limits, is unlikely to have guaranteed the whole integrity of ground surface material because of putting the stressed horizontal bar that severs.Above-mentioned net sheet helps combining closely of road surface filler in the structure of thickness direction.

The utility model mainly adopts high-density polyethylene material to make, and wherein can add high temperature resistant and the rigidity additive, to strengthen the heat resistance and the tensile strength of major ingredient.

Claims (2)

1, pavement strengthening anticracking net sheet is characterized in that: adopt polymeric material to make plastic deeping, the mesh length of net sheet is 50-60mm, the mesh width of net sheet is 40-50mm, the vertical muscle width of mesh is 4-6mm, and mesh horizontal bar width is 4-6mm, and net muscle thickness is 2-4mm.

2, net sheet as claimed in claim 1 is characterized in that: described mesh horizontal bar is curved, and horizontal bar thickness is greater than vertical muscle thickness, and on net muscle thickness direction, vertical muscle is positioned at the horizontal bar middle part, respectively reserves uniformly-spaced vacant up and down.
