Basic knowledge of electronic vehicle weighbridge
1. The foundation drawing is the basis for the user to design the foundation. The user can determine it according to the local soil pressure resistance, frozen layer, water level and building requirements. The thickness, diameter, spacing and quantity of reinforced concrete are only for reference.
Note: 50cm space is reserved on both sides of the scale body (driving direction) for installation and commissioning.
2. The front and rear inclined approach roads shall be constructed separately from the main foundation. After each bearing the key load, ensure that the settlement is less than 2mm. The foundation shall be paved with crushed stone lime soil, and the following shall be compacted with plain soil.
3. The single load of 8 bearing embedded parts shall be more than 25000 kg, the single foundation in use shall be free of cracks, and the levelness of 8 bearing embedded parts shall be ≤ 3mm, and the bearing embedded parts shall be prepared by the user.
4. 8 bearing embedded parts shall be installed with reserved holes. In order to facilitate secondary grouting, the center of bearing embedded parts can be properly drilled with the reserved hole size of 400 × four hundred × 350 During site construction, it can be enlarged properly. After the foundation concrete is solidified, the secondary grouting shall be carried out. The cement proportion of the concrete for grouting shall be increased and full grouting shall be ensured. No air holes, bubbles and inclusions are allowed. The concrete can only be used after it is completely solidified.
5. Compaction of plain soil requires that the bearing capacity of the foundation R ≥ 1 × 105N/m2, 30-40cm thick crushed stone shall be paved on the top and compacted. The whole bottom plate shall be poured with concrete at one time. The concrete shall be mixed with 425 # or above Portland cement. The main load-bearing reinforcement in the beam shall be Grade II deformed steel, and the rest shall be Grade I, ≤ 90 × 10 The angle steel can be embedded only after welding and straightening, and the non straightness after embedding shall not be greater than 3mm.
6. The protective layer under the foundation beam is 35cm, and the protective layer in the slab is 20cm.
7. The user of cable conduit can select 2 # polyethylene pipe according to the position given in the foundation, and should try to reduce bending, and put a steel wire with a diameter of 2mm in order to be used as a lead when threading the cable. The power supply of the weighing room must be configured
The ground wire, sensor, instrument and computer are grounded independently, and the grounding resistance is less than 4 Ω.
8. The slope approach lengths of 3000 and 8000 are reference dimensions, which can be determined by the user according to the site conditions, but the applicable ones shall prevail.
9. The number in the reinforcement drawing is ② ④ ⑦ ⑨. The end face of the stirrup must be bent 90 °. The elbow length is about 5cm. The elbows of two adjacent stirrups must be staggered.
