Description

Basalt fiber geogrid

Technical Field

The utility model relates to a basalt fiber geogrid among the building element technical field.

Background

In the engineering construction of roadbeds, dam dikes, slope protection lacing bars, retaining walls, soft soil foundations and the like, in order to ensure the engineering quality, the friction action generated by the reinforcement material and the soil body is usually adopted to be arranged in the soil body, and the stress is transmitted to the reinforcement material to form the filling of buildings such as reinforced earth lattice walls, reinforced earth foundations, reinforced earth abutment, reinforced earth cushion and the like.

The existing geogrid is disclosed as 'an improved basalt fiber geogrid' in Chinese patent CN207987448U, and the geogrid comprises a geogrid body woven by warp sheets and weft sheets, wherein the warp sheets are formed by basalt fiber bundles dried by asphalt treatment, and the weft sheets are formed by basalt fiber bundles dried by asphalt. This patent utilizes characteristics such as the environmental protection of basalt fiber material self, ageing resistance, long service life, has guaranteed geogrid's life and environmental protection characteristic, but it still has following problem: warp and weft that form are woven by the basalt fiber bundle, in the node position that intersects, warp and dimension can't form effectual effort, and then lead the time spent, corresponding soil matrix stretching resistance is not strong, and in addition, the connecting force between geogrid body and the soil matrix is also not enough.

Disclosure of Invention

An object of the utility model is to provide a can improve alternately node position effort, improve the basalt fiber geogrid of effort between geogrid body and the corresponding filler simultaneously.

In order to solve the technical problem, the utility model provides a technical scheme as follows:

the basalt fiber geogrid comprises a grid body, wherein the grid body comprises at least two lacing wire groups, each lacing wire group comprises at least two lacing wires which are arranged in parallel and are formed by basalt fiber bundles, the lacing wires of different lacing wire groups are intersected to form a plurality of intersection nodes, the periphery of each intersection node is provided with an upper side and a lower side which protrude out of a node forming bulge of the grid body, and the lacing wires of all the lacing wire groups at the intersection nodes are fixed together through the node forming bulges.

The node forming protrusions are vertically arranged cylindrical structures.

The lacing wire group has three, and the lacing wire of different lacing wire groups encloses into triangle-shaped grid structure.

One or at least two tie bar forming bulges which are arranged at intervals along the axial direction of the tie bar are arranged on the corresponding tie bar between two adjacent cross nodes.

The periphery of each lacing wire is wrapped with a wrapping adhesive layer which is integrally formed with the node forming bulge and the lacing wire forming bulge.

The periphery of each lacing wire is wrapped with a wrapping adhesive layer which is integrally formed with the node forming bulges.

The utility model has the advantages that: the utility model discloses in, state that the cross node periphery is equipped with the downside and all outstanding in the node shaping of grid body is protruding, and the lacing wire of each lacing wire group of cross node passes through the protruding fixed together of node shaping, the basalt tow through the node shaping arch with the cross node is fixed together, guarantees the engaging force of different lacing wire intergroup tows, simultaneously because the bellied existence of shaping, lie in that after the filler (say so that soil, pitch etc.) contact, form the retaining force between filler and the shaping arch, consequently improved the effort between filler and the geogrid body, improved the tensile strength of filler self.

Detailed Description

An embodiment 1 of the basalt fiber geogrid is shown in figures 1-2: including latticed grid body, the grid body includes two lacing wire groups, each lacing wire group all includes a plurality of parallel arrangement's the lacing wire that constitutes by the basalt fiber bundle, in this embodiment, the lacing wire of one of them lacing wire group is weft lacing wire 1, the lacing wire of another lacing wire group is warp lacing wire 2, the lacing wire of different lacing wire groups is arranged perpendicularly each other, the lacing wire of different lacing wire groups alternately forms a plurality of cross node 3, the peripheral parcel of each lacing wire has parcel glue film 7, parcel glue film 7 helps guaranteeing basalt fiber bundle's wholeness. The periphery of the crossed node is provided with a node forming bulge 5, the upper side and the lower side of the node forming bulge protrude out of the grid body, the lacing wires of each lacing wire group at the crossed node are fixed together through the node forming bulge 5, and the node forming bulge and the wrapping glue layer 7 are integrally formed. And a lacing wire forming bulge 6 is arranged on the corresponding lacing wire between the two adjacent cross nodes, and the lacing wire forming bulge and the wrapping glue layer 7 are integrally formed.

When the basalt fiber geogrid is used, the basalt fiber geogrid is paved in a filler, the filler refers to soil, asphalt and the like, the filler can be filled with the upper side and the lower side of the basalt fiber geogrid, and the filler can be filled between the node forming protrusions and the tie bar forming protrusions. The lacing wires of different groups at the crossed nodes are fixed together by the node forming bulges, when one lacing wire is stressed, the tensile force can be shared by other lacing wires, the tensile capacity of the geogrid body is improved, and the tensile capacity of a filling is further improved.

In other embodiments of the present invention, the number of the tie bar forming protrusions may be set as required, for example, two, three or other numbers, and certainly, the tie bar forming protrusions may not be provided; the node forming projections may also be of a square column structure or a spherical structure.

An example 2 of a basalt fiber geogrid is shown in fig. 3: embodiment 2 differs from embodiment 1 in that there are three tie bar sets, and the tie bars 8 of different tie bar sets intersect to form a triangular structure.
