Steel-plastic the grid construction technology (1) First, accurate release the roadbed slope Line, in order to ensure the roadbed width on each side of the widened 0.5m, drying good basal soil leveling 25T vibratory roller static pressure twice, again 50T shock pressure of four times, uneven artificial leveling. (2) foreshadowing 0.3m thick (coarse) sand, artificial mechanical leveling, 25T the vibratory roller HIP twice. (3) the laying of geogrid geogrid laying underside should be smooth, dense, should generally be tiled, straightened, and must not overlap not curl, kink the adjacent two geogrid need lap 0.2m, and along the base every 1 meter horizontal on the lap portion of the geogrid No. 8 wire interspersed every 1.5-2m fixed to the ground with a U-shaped nails, and laying on the grill. (4) laid the first layer of geogrid, began to fill set up the second layer of 0.2m thick (coarse) sand, its method: auto transport sand to the site to unload on the embankment on one side, then in time to push forward with a bulldozer , the first roadbed on both sides within two meters of reclaimed 0.1m, the first layer of geogrid fold turned up then fill in the 0.1 m (coarse) sand is prohibited on both sides of filling to the middle and advancing to prohibit various kinds of mechanical geogrid without filling in the sand (coarse) traffic operations, this will ensure that the geogrid flat can not afford to drum, do not wrinkle, until the second layer (coarse) sand formation, horizontal measurement to prevent the filling of non-uniform thickness, to be copied level correct 25T vibratory roller static pressure twice. (5) a second layer of geogrid construction method is the same method with the first layer, and finally filling 0.3m in the sand (coarse), filling the same with the first layer, with a 25T compactor after hydrostatic twice, so subgrade reinforcement dealt. (6) in the third layer (coarse) sand compacted along the road longitudinal slope on both sides of each laying geogrid two lap 0.16m, and connected the same way, then start earthwork construction jobs laying geogrid slope protection, must be on each floor measuring laying edges, each side to ensure slope after renovation geogrid buried slope 0.10m. (7) slope geogrid filling each two-layer soil thickness of 0.8m when required on both sides at the same time laying a layer of geogrid, and so on until the shop to the hard shoulder under the surface of the soil. (8) Subgrade Slope renovations timely and stone protection to the foot of the slope of the dry puzzle piece into the roadbed except each side widened 0.3m and set aside 1.5% fall. Product Features 1, high-strength steel wire braided steel-plastic composite grille tension by Jingwei commitment to produce high tensile modulus at low strain capacity, aspect, give full play to the synergy of the rib grille insert lock role of soil . 2, steel-plastic composite grid aspect to the ribs of steel wire Jingwei woven into a network, the overwrap layer forming, wire overwrap coordinating role, undermining the very low elongation (not more than 3%). Steel-plastic composite geogrid main force unit for the wire, very low creep. Processing plastic surface through the production process, to suppress the rough pattern, in order to enhance the the grill surface roughness, increase the friction coefficient of the steel-plastic composite geogrid soil. 4, steel-plastic composite grille width up to 6m, and efficient, the reinforcing effect of the economy. 5, the steel-plastic composite grille with a high density polyethylene can ensure not affected by pH and salt solutions: at room temperature, or the erosion of the oils; against not be dissolved in water or a microorganism. Meanwhile, the properties of the polyethylene polymer is sufficient to resist ultraviolet radiation caused by aging. Grille vertical and horizontal ribs synergy force does not produce nodes crack or breakage. Practical engineering, compacted filler, so not subject to the erosion of the UV light and oxygen, and therefore fully meet the requirements of the construction of the permanent works. Uses steel-plastic grille applies to highways, railways, embankments, abutments, construction of access roads, docks, revetments, levees, dams, tidal flats governance, freight yard, residue field, airports, sports grounds, green construction, soft ground reinforcement, retaining wall , slope protection and road surface anti-the inferior civil engineering, various dams and embankment reinforcement, slope protection, wall reinforcement, One, Triple qi. Nine, One, the Triple One II. One, Ba Ba, Oriental sensitive. Large airport, parking lot, pier freight yard permanently hosted foundation reinforcement. Steel-plastic plastic grille is used to increase the carrying capacity of the road (ground) base to extend the service life of the base of the road (ground). Steel-plastic plastic grille is used to prevent the road (ground) surface subsidence or cracks, keeping the floor neat appearance. Steel-plastic plastic grille for convenient construction, saving time, effort and shorter cycle times, reduce maintenance costs. 4 steel-plastic plastic grille used for prevent culverts cracks. 5 steel-plastic plastic grille for enhanced soil slopes to prevent soil erosion. 6 steel-plastic plastic grille is used to reduce the cushion thickness and cost savings. 7 steel-plastic plastic grille for the stability of a green environment supporting slope grass mat. Convex node steel plastic grille product construction method: a. The geogrid laying surface should be relatively smooth, ply inspected and accepted, in order to prevent vertical skew phenomenon, first press the line width in ply draw white lines or hanging , to start laying, then end U-nailing grille (per meter wide nailing four uniform distance fixed); the b fixed grille end, pavers or artificial means grille slowly pull forward shop manual investigation once every shop ten meters long, until the roll grille Puwan holes under roll, long before the operation is the same; c. then shop: roll length as laying segment laying quality segment length should shop grille covered, and then the overall check, and then followed by the laying of the next paragraph, when laying the next paragraph, grille and grille to overlap a grid clear distance for the lap length, and tied with continue the line fixed forward direction Shop of the second paragraph. And so on, operating requirements with the former. Steel-plastic grille of the paved surface of the steel-plastic grille construction considerations should be relatively flat, paved layer inspected and accepted, in order to prevent vertical skew phenomenon press width paving layer draw a white line or hanging line, that is, may begin paving, then with nails fixed end portion of the grille (per m wide with nails 8, uniform distance fixed), the end portion of the fixed grille, pavers grille slowly pulled forward SHOP , every shop 10 meters long artificial tighten and tone straight until the roll grille Puwan holes volume operation with the former Puwan roll after 6T-10T road roller from the starting point to move forward to the direction of the RCC again, in the surface layer and the leveling layer (such as paving steel roller compactor appropriate; 2005 triple. wantonly, Ba II, Ba II.
