What are the key points to consider when establishing a mineral warehouse on the coast of Nigeria?

👉 Project location: Nigerian coast 👉 Project type: Mine warehouse (span 100 metres, length 125 metres) 1. Structural Design  Span and Length:  The mine warehouse has a span of 100 metres and a length of 125 metres, employing a large-span steel structure design to ensure structural stability and load-bearing capacity.  It is recommended to use a steel truss structure or space frame structure to meet the large-span requirements and optimise material usage.  The structural design must consider wind loads, seismic loads, and dynamic loads during the operation of the bucket wheel excavator. Foundation Design:  Since the project is located by the sea, the foundation may be relatively soft. It is recommended to use deep foundation design (such as pile foundations) to ensure structural stability.  Foundation construction must consider the impact of groundwater levels and saline-alkali environments, and foundation reinforcement should be carried out when necessa...

The ground assembly method can be divided into several construction methods:

a. On-site assembly and overall jacking

The space frame is assembled on the ground, and the fulcrum is set at the position of the column, so there is no need to stagger it, and then the space frame is raised to the design level with a jack.

b. On-site assembly and overall improvement

The space frame is fully assembled on the ground, and then the space frame is raised to the design level by using the plate lifter or the sliding form lifting machine.

c. On-site assembly, overall hoisting, and high-altitude displacement

This method is to stagger the grid support from the position of the support column when assembling on the ground (when individual rods affect the lifting, they can not be assembled, but should be properly reinforced). Then use the hoist to lift the space frame, and then move the space frame after it exceeds the top of the column, so that the support of the space frame moves to the top of the column and then it is in place.
