Second, the user according to the provided basic design drawings, combined with on-site geological conditions, and then carry out construction design. Three issues must be specially addressed in the construction design:
(1) The basic soil carrying capacity (ground endurance) requirement is not less than 20t/m2. If the on-site geological conditions do not meet this requirement, reinforcement must be done.
(2) Foundation excavation must be excavated below the local frozen soil line.
(3) For shallow foundation pits, drainage channels must be designed. The foundation pit-free foundation should also consider the surrounding drainage problem to ensure that the truck scale will not be flooded into the water due to rain.
Third, the basic concrete longitudinal and horizontal reinforcement mesh requires that more than 50% of the intersections be bundled with 16# iron wire, and be connected to the iron baseplates with steel bars (used as the load cell ground wire).
IV. Pre-embedded parts (iron floor, anchor bolts, angle guard, etc.) in the foundation construction shall be provided by the user. During the construction, measures must be taken to ensure the correct position of the anchor bolts and the iron floor. For this reason, it is recommended to adopt the method of secondary irrigation to locate, and it must be ensured that no void is formed between the iron floor and the concrete. The construction must ensure that the level and elevation of each iron floor meet the basic design requirements. The difference in the height of the center of each iron floor should be less than 2mm, the horizontal inclination of the iron floor should be less than 1/500, and the diagonal deviation of the center distance of each iron floor should be less than 2mm.
Fifth, after the completion of the foundation construction, care must be taken. In order to shorten the construction period and maintenance time, it is allowed to add "early strength agent" to the concrete during construction. The scale platform shall not be installed when the concrete has not reached the design strength.
6. The pound room design of the electronic truck scale is determined by the user according to actual needs: A pound ground wire and a 220V power supply must be set up in the pound room for use by the weighing control instrument. The pound room must be close to the weighing platform. Special circumstances need to be informed in advance with our company.
7. Users in northern regions should consider the issue of heating in winter. Conditional users are advised to use air conditioning or heating, and coal stoves must not be installed in pound rooms.
8. The signal cable from the weighing platform is led out from the weighing platform and enters the pound room through the metal pipe. It is recommended to use a metal pipe and put on the iron lead of the cable at the same time.
First, the basic structure of electronic truck scale (floor scale) is divided into two kinds: shallow pit and no pit. Our company provides design drawings for users according to the needs of users.
