Section steel composite support is assembled on site by precast steel components. Compared with concrete support, it does not need to wait for concrete curing period, the construction period is shorter, and the demolition is convenient, and will not produce engineering waste, and the steel components are recycled again, and the cost is relatively lower.

Macau new townAareaB4Foundation pit supporting project

The project foundation pit circumference approx410m, with an area of about10698 ㎡, the maximum excavation depth is 15.45m. The project uses the innovative technology of Shanghai's strong foundation --Steel support technology for prestressed fish-belly foundation pit This is the first application of prestressed fish-belly foundation pit steel support technology in Macao. Compared with the local traditional steel support technology, the prestressed fish-belly foundation pit steel support technology adopts standard components and bolts for assembly and connection, which makes the technology have the following advantages:

(1To save time. The use of bolts on site assembly, avoid a lot of welding work, fast speed, short construction period;

(2(Green environmental protection. Component assembly, disassembly, no construction waste, component recovery rate is high;

(3There is plenty of room for digging
