Construction method of glass fiber grid
1, nail fixation method of glass fiber geogrid, the first end is fixed on the lower structure has been spreading viscous layer of asphalt with fixed iron and nail, nail available hammer or a nail gun into the grille of longitudinal tensioned and sectional fixing each segment length of 2-5 meters, the cement concrete pavement. According to the shrinkage joint spacing section. The position of the steel nail is located at the joint. When the grid is tensioned, the vertical and horizontal direction of the steel bar is in a straight and tight state.2, the grid lap distance: longitudinal joint lap distance of not less than 20 cm, the transverse overlap distance of not less than 15 cm, longitudinal lap should be according to the asphalt paving direction, will be on the top of the previous one.
At present, the commonly used glass fiber geogrid has two kinds of self adhesive and no self adhesive. The adhesive tape can be directly laid on the flat base. The materials needed for nail fixation:I. 40 x 40 x 0.3 mm of fixed iron, the requirements of flat angleIi. 2 inch steel nails (high quality cement nails)
2, road surface conditionPavement must be clean, clean, dry, temperature at 5 degrees Celsius -60 degrees celsius.3, product preparationSelf adhesive fiberglass geogrid shall not be stored in a dry environment on the site to keep the viscosity.4, matters needing attention(1) workers must wear gloves when contacting self adhesive fiberglass grille.(2) when the self adhesive glass fiber grating is used for passing through obstacles, it is necessary to use a knife to cut off the geogrid.(3) it is not allowed to fold when laying self adhesive fiberglass grille, so there must be enough tension in the course of laying.(4) the overlap of the end part is 75-150 mm, which ensures that the overlap is along the laying direction.(5) overlapping parts on both sides of 25-50 mm.(6) only the construction vehicle or the emergency vehicle shall be allowed to walk on the ground after being laid and rolled down, but it shall be ensured that the damage of the geogrid shall not be caused by the turning or braking of the vehicle.
3, can not be nailed on the glass fiber grille, can not be directly hit the glass fiber grating with a hammer, after fixing, if the nail is broken or loose iron, you need to be fixed.4, after the completion of the glass fiber grille is fixed, must use roller roller roller stability. So that the grid and the surface of the road is firmly adhered to strictly control the delivery of vehicles mixed in the grid layer on the car to prohibit the emergency steering, emergency braking and pouring of mixed material, in order to prevent damage to the construction of fiberglass grille. 1, preparation work:Complete all of the filling, filling pit, foundation reinforcement and leveling layer laying.
