How large should the holes reserved for equipment be? What is the basis?
The key is to determine what purpose the reserved hole is intended for. If it is a hole reserved for the equipment foundation, it must meet the requirements of the civil engineering foundation design. If it is a hole reserved for the equipment itself, then the dimensions of the equipment and its installation requirements are crucial, as these factors determine whether the hole meets the needs for equipment installation, lifting, and maintenance.
The key lies in the purpose of this reserved hole. If it is intended for the foundation of equipment, then it must meet the requirements of civil engineering foundations. If it is a reserved hole for the equipment itself, then the relevant factors include the equipment’s dimensions, installation requirements, and manufacturing conditions, all of which must satisfy the needs of equipment installation, lifting, and maintenance
The size of the holes to be left is determined based on the size of the equipment and the way it is installed. For smaller devices, an addition of 200 to their outer diameter is generally sufficient. For larger devices, if they are installed in an upright position, the same principle applies as for smaller devices. If the device needs to be turned over at the installation site, then the calculation should take the device’s height into account; otherwise, the beams can simply be pre-arranged accordingly
Firstly, it is necessary to ensure that the equipment can be lifted and placed into the pre-designed hole; attention must also be paid to the insulation thickness of the equipment. Generally, the diameter of a circular pre-designed hole should be 200 mm larger than the diameter of the equipment, while for holes of irregular shapes, an additional 100 mm is sufficient on each side.
Considering the various conditions of the equipment, ensuring that it can be placed there is the key
