Abstract
The utility model discloses a new plastic grid which is mainly used for highways and urban road engineering. The utility model has a network structure which is composed of net ribs and nodes. The utility model has the advantages of no corrosion, shock resistance, low cost, convenient operation, etc.
Description
The utility model relates to a kind of grid that is used for the earthwork engineering field, particularly is applied to highway and urban road engineering.
Grid of the prior art is to be worked out by the wire of different size, makes complicated.Not shock-resistant, time one long easy deformation and corrosion, cost height.General only limit is applied to fence, can't use in highway and urban road engineering.
Task of the present utility model provides a kind of geo-grid that is mainly used in highway and urban road engineering aspect.
The utility model is achieved in that a kind of geo-grid, is characterised in that: by being that net rib 1 and the node 2 that raw material is made formed the open cell mesh lattice structure with the thermoplasticity resin.
Its network is shaped as rhombus or square.
The utility model is compared with prior art has good dimensional stability, shock-resistant, do not corrode, cost is low, light weight, easy for operation, be mainly used in highway and urban road engineering, also can be used for the bank protection and the maintenance at fence, railway, water conservancy, harbour, administer fields such as desert and geotechnical engineering.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structure chart of carpenter's grid.
Fig. 2 is the A-A sectional view of carpenter's grid.
Embodiment of the present utility model as shown in Figure 1 and Figure 2, the open cell mesh lattice structure of forming by net rib 1, node 2.It is that masterbatch adds various additives by high-density polyethylene mainly, adopts the plain net extrusion equipment, through the high temperature heating, melt extrudes, and dissects, batches etc. that explained hereafter comes out again through traction.The mesh shape of building grid is a rhombus, also can be designed to square.The utility model is used for highway, when the urban road surfaces reinforcement is mated formation, can mats formation in the pitch bottom, in asphaltum concrete cover-layer bottom or the bitumen layer.The soil and the interlocking in eyelet that gathers materials, the effect of each net rib is equivalent to an independently anchor point.Its tensile strength in road surface structare layer is improved, tensile stress is evenly distributed in than in the large tracts of land scope, alleviate the creep effects that the bituminous texture layer produces greatly, finally reach the purpose that prevents the flexible pavement cracking, effectively overcome ubiquitous in the present asphalt concrete pavement " cold cracking " and high temperature rut obvious defects.
Claims (2)
1, a kind of geo-grid is characterised in that: by with the thermoplasticity resin being the open cell mesh lattice structure that the net rib [1] made of raw material and node [2] are formed.
2, geo-grid according to claim 1 is characterized in that: its network is shaped as rhombus or square.
