Prestressed fish-belly steel bracing for foundation pitIt is a prefabricated steel support system using high strength steel as the main material and applying prestress. Suitable for general excavation depth, regular plane shape, long and narrow shape Foundation pit engineering.

Construction method:

Firstly, the positioning is measured, and the straightness of the positioning must be precisely controlled to ensure the axial compression of the steel support.

Before installation, the control points should be made on the enclosure body, and then the support embedment on the enclosure body is respectively guided to test;

The hoisting of steel support, from the perspective of reliable force, vertical and horizontal steel support generally does not use overlapping connection, and the same elevation connection with larger plane stiffness;

After the steel support is placed in place, the crane will put the hydraulic jack into the pressure position, connect the oil pipe and open the pump, apply the prestress step by step according to the design requirements, and then fix;

When the support is removed, the steel support in the foundation pit should be removed according to the construction process, and the prestress should be removed before the support is removed.
