​Unattended electronic floor scale foundation construction technical requirements

1. Vehicle number identification system

 1.1 the antenna and power supply of vehicle number identification system are installed on the beam inside the awning. A threading pipe is reserved beside the awning column near the pound house, exposing the height of 1500mm. A traction wire is pre-threaded in the tube to prepare for threading and to avoid dead bends as much as possible.

 2. Pound room, car gear and signal light

 2.1 the length, width and height of the pound room are determined by the user.

 2.2 two car stop and light is 600 x 600 concrete foundation, the minimum depth of 400 mm, highly customised (chassis height 1050 mm) by the user, the reserved  210 x 210 Ø 18 hole 4, intermediate for embedded threading pipe, through the car stop at one end and lamp base plate center, above height 100 mm, one end connected to the operation room, can not have water and debris into the tube wear a traction steel wire, used for threading, at the same time try to avoid death.

 2.3 the relative position between the two floor scales and the operation room shall be determined independently by the user according to the site and project situation.

 2.4 the car gear shall be lifted to a height of 2.5  meters. If installed in the awning, space shall be reserved.

 3. Weighbridge foundation

 3.1 cable conduit users can choose 2# polyethylene tubing according to the position given in the foundation, and should try to reduce the bending, and wear a 2mm diameter steel wire, in case of the cable as a lead. Pounds of room power supply ground wire must be provided, sensors, instrumentation and computer such as independent grounding, grounding resistance less than 4 Ω.

 3.2 the length of the slope in the figure is 3000 and 8000 as the reference size. Users can make their own decisions according to the site conditions, but the applicable ones shall prevail.

 3.3 foundation drawing is the basis for user design. The user can determine according to the local soil pressure resistance, freezing layer, water level and building requirements, etc. The thickness of reinforced concrete and the diameter, spacing and quantity of reinforcement are only for reference.

 3.4 the front and rear ramp approach shall be constructed separately from the main foundation. After each key load is borne, ensure that its subsidence is less than 2mm. The foundation shall be paved with gravel and lime, and the following shall be compacted with plain soil.

 3.5 8 single load of load-bearing embedded parts shall be greater than 25000kg, single block foundation shall not have cracks in use, and the horizontal degree of bearing embedded parts in 8 parts shall be less than 3mm, and the load shall be borne by the user himself.

 3.6 Up with eight of bearing installation area should be set aside to leave a hole, for the convenience of secondary grouting, bearing up with center can be appropriately drilling, to leave a hole size 400 * 400 * 350 site construction can be appropriately enlarge, foundation after concrete setting again for a second grouting, grouting concrete cement ratio increases, and ensure the filling and filling, are not allowed to appear porosity, air bubble and inclusion, all solidify rear can use.
