Points needing attention in the construction of weighbridge foundation
Points needing attention in the construction of weighbridge foundation
The foundation pit of the weighbridge has two conventional forms, one is without foundation pit, and the other is shallow foundation pit. Shallow foundation pit refers to the installation method in which the weighbridge is installed in the foundation pit, and the surface of the weighing platform is level with the ground. The weighbridge without foundation pit is installed above the ground, which can be cleaned frequently without water accumulation, and the cost is relatively cheap. Generally, the installation method of platform weighbridge without foundation pit is selected. The weighbridge foundation construction shall have good drainage channels, which will not flood the weighbridge due to rainstorm or mountain torrent. For shallow foundation pit, drainage channels shall be set. In addition, there must be a straight road with sufficient length at both ends of the weighbridge for vehicles to get on and off the platform, and the straight road at both ends must be at least equal to the length of the platform.
Pay attention to the construction of weighbridge foundation
The concrete foundation of the weighbridge must be poured. The foundation must be excavated below the local frozen soil line. During the construction, the concrete grade shall be guaranteed. When pouring the embedded parts, the levelness, location and other geometric dimensions shall be guaranteed. When pouring the concrete, the embedded parts shall not be displaced. After the foundation pouring is completed, it shall be cured according to the civil engineering specifications. Only when the concrete reaches the design strength index can the weighbridge be installed. If the curing period is to be shortened, it is allowed to take measures such as adding "early strength agent" under the guidance of professional technicians during construction. For lightning protection, you should set a grounding pile according to local conditions and ensure that the grounding resistance is less than 4 ohms. An iron pipe should be laid from the center of the scale platform to the weighing room for threading signal cables.
During the foundation construction, please refer to the foundation drawing of the weighbridge provided by Shanghai Yingheng Hengheng. The general construction period plus the foundation maintenance period takes about 10 days.
Weighbridge room:
The weighbridge room should be close to the weighbridge so that weighing instruments, computers, printers and other equipment can be placed. In addition, it should be ensured that the weighing clerk can also contact the driver, transfer the weighing list, ensure that cars are loaded on the scale, identify the license plate number and check the goods.
Weighbridge installation:
In most cases, the manufacturer is responsible for the installation and commissioning of the weighbridge, and the following things need to be prepared:
Two cranes and jacks (more than or equal to 5t).
After installation and commissioning, it can be officially put into use only after passing the verification and issuing the certificate of conformity.
