AI Technical Summary
In bridge anchorage foundation pit operations, the excavation, excavation, concrete pouring, and installation of anchorage components for ultra-large and ultra-deep foundation pits present problems such as high cost, high labor intensity, and long construction period. In particular, the concrete pouring efficiency in deep and large foundation pits is low and the quality is difficult to guarantee, making it difficult to select crane equipment.
A cable-stayed crane system is adopted, including crane rails and cable cranes arranged in parallel on both sides of the foundation pit. A trolley is equipped on the sling, which consists of a positioning and moving part, a winding part and a lifting part. The earthwork development, concrete pouring and anchoring component lifting in the foundation pit are realized by the synchronous winding and unwinding of the sling. The bridge railing cableway and anti-sway part are combined to stabilize the lifting process.
It enables efficient earthwork excavation, concrete pouring, and anchoring component installation within the foundation pit, reducing equipment requirements, lowering costs, improving construction efficiency and quality, and is highly adaptable to various foundation pit shapes.
