Abstract
The utility model discloses a coating consolidation type glass-plastic composite geogrid which comprises longitudinal strips that are distributed separately. Transverse strips and the longitudinal strips are intercrossed at intersections for forming rectangular grid units which are connected continuously. Each strip has a certain width and thickness. Each strip coats glass fiber yarns, and the coating consolidation type glass-plastic composite geogrid is characterized in that a consolidation point is coated at each intersection of the geogrid. Compared with the prior art, the coating consolidation type glass-plastic composite geogrid has the following advantages: high strength, high corrosion resistance, etc.
Description
Technical field
The utility model relates to a kind of geo-grid---be coated with the geo-grid of glass fiber in especially a kind of
Background technology
It is at present domestic that to be used for soil body reinforcement or reinforcement material (being generally called geotechnological material) that geotechnical engineering builds various in style, its functional performance characteristics, and conforming, each is variant.As: simple tension plastics geo-grid, biaxial tension plastics geo-grid, three-dimensional stretched plastic geo-grid, steel is moulded compound geogrid etc.
The physicochemical properties that plastic tensile class grid is subject to raw materials for plastics production influence its intensity reduction, elongation at break height 〉=10%; Creep-resistant property is poor, and thermal stability is poor, easily causes engineering cracks and fracture, causes the engineering failure, causes damage.
It is carbon spring steel wires (GB4357-89) that steel is moulded the used reinforcement material of compound geogrid, though intensity is big, but be vulnerable to the corrosion of adverse circumstances such as acid, alkali, salt, especially for deep ocean work, bank strengthening, because of being subjected to the seawater erosion to cause intensity low for a long time, poor corrosion resistance has shortened application life, therefore can not satisfy the permanent work requirements on Construction fully.
To sum up, there is following defective in the existing geotechnological material in domestic market at present:
Tensile strength low≤50 KN/m (biaxial tension plastics geo-grid, three-dimensional stretched plastic geo-grid);
2. elongation at break height≤10%;
3. acid and alkali resistance, salt chemistry aggressivity is poor;
The interlocking ability of gathering materials (place is little because of mesh node) causes frictional force to reduce, so be restricted in the engineering scope of application
Summary of the invention
At the problems referred to above, the utility model provides a kind of glass to mould compound geogrid, has the tensile strength height.
For achieving the above object, the technical scheme that the utility model adopted is as follows:
The fixed formula glass of a kind of coating is moulded compound geogrid, comprise longitudinal band spaced apart and longitudinal band, laterally band and longitudinal band are in square-grid unit that the interlaced formation of joint is connected continuously, described band has certain generous and thickness, be coated with glass fiber yarn in it, the joint place of described geo-grid is coated with anchoring point.
Above-mentioned glass is moulded compound geogrid, described longitudinal band and horizontal band joint position overlap joint; Described longitudinal band and the horizontal mutual interlacing of band joint.
Above-mentioned glass is moulded compound geogrid, and band is pressed with annular knurl outward.
Above-mentioned glass is moulded compound geogrid, and described glass fiber yarn is a net structure; Described glass fiber yarn is the parallel fibers bundle.
The beneficial effects of the utility model show:
Increased glass fiber material and replace other reinforcement materials in band, for example steel wire etc. makes the biaxial tension breaking strength of this product can reach more than the 120KN/m; Elongation at break≤3% can be resisted all kinds of physical abrasion and chemical erosion, can also resist bioerosion and climate change, guarantees that its performance is unaffected.
Increase annular knurl, increased intensity on the one hand, on the other hand, it is more firm that the annular knurl of increase makes that glass fiber contacts with plastic layer.
Mesh node has adopted the coating crowing technique, node is increased strengthen, and the antistripping tearing strength is greatly improved, and the soil body is had stronger interlocking, and interlock ability, frictional force have improved more than 2 times.
With Shooting Technique whole node is got up with plastic overmold, make node firmly seamless on every side, increased the tearing toughness of node, the height of node (thickness) increases, and gives full play to the interlock action of grid to the soil body, has improved friction factor.Stability to engineering has had reliable guarantee.
To sum up, the utlity model has following beneficial effect:
It is to be to be main material with the glass fiber that high-tensile, low elongation---glass are moulded compound geogrid, has very high non-deformability, and ultimate tensile strength reaches 300MPa, fracture elongation≤3%;
No long-term creep---because of the band extexine adopts high-density polyethylene material, the ability that possesses resistance to deformation under the situation of long duration load, promptly creep-resistant property is very important, two kinds of materials unite two into one, its performance advantage is replenished mutually, guarantees that product can keep performance for a long time.
The fusion temperature of heat stability---glass fiber is more than 1000 ℃, and this has guaranteed that glass moulds compound geogrid bears heat in different thermal environments stability.
Physical and chemical stability---handle through the special process prescription, glass is moulded compound geogrid can resist all kinds of physical abrasion and chemical erosion, can also resist bioerosion and harsh weather and change, and guarantees that its performance is unaffected.
Interlocking gathers materials---because glass is moulded compound geogrid is net structure, and vertical, horizontal crossbar contact height (thick) has so just formed mechanical interlocking.This restriction has hindered the motion of gathering materials, and makes bituminous mixture be subjected to can to reach better compaction state under the situation of load, higher weight capacity, better Load Transfer performance and less distortion.
It is a kind of light weight that application property---glass is moulded compound geogrid, possesses the Plastic Flat veil material of certain flexibility, is easy to on-the-spot cutting and continuous, also can overlappingly overlap, and easy construction does not need special construction machinery and professional and technical personnel.

Five: the specific embodiment:
Be described in detail with the integrated structure schematic diagram with to the utility model below:
The fixed formula glass of a kind of coating is moulded compound geogrid, comprise longitudinal band spaced apart and longitudinal band, laterally band and longitudinal band are in square-grid unit that the interlaced formation of joint is connected continuously, described band as shown in Figure 1, it has certain generous and thickness, be coated with glass fiber yarn in the band, band is pressed with annular knurl outward.
Described glass fiber yarn can adopt side by side and along the glass fiber bundle that strip direction is extended, also glass fiber can be formed net structure, and net structure can layering or intersected mutually as required, as shown in Figure 2.
Realize following dual mode according to the joint of longitudinal band and horizontal band is different:
Mode one: overlap joint
Laterally band and longitudinal band are positioned at two planes, and promptly laterally band is positioned at a plane, and longitudinal band is positioned at another plane, and two planes join, and overlapping formed rectangular element can select as required.
Mode two: braiding
