proposed to replace concrete foundation with prefabricated foundation, and introduced the advantages, construction technology and precautions of the prefabricated foundation. To overcome the defects of cast-in-place concrete foundation, Fan et al. The foundation can work repeatedly without installing, with low amortization cost, so it has certain engineering application value. studied the construction technology of prestressed cross polygona assembled fiber concrete tower crane foundation, which is a multi-purpose combination and suitable for different forms of tower foundations. Tan proposed a prefabricated steel structure tower crane foundation and conducted in-depth research. Zuo carried out in-depth research on the design, positioning and construction of steel lattice column tower crane foundation. Sun conducted research on the structural design and mechanical properties of cross-shaped mobile tower crane. īased on the application status and existing problems of tower crane foundation, Ji put forward some ideas and structures for foundation design. designed and calculated the square tower crane foundation with ANSYS three-dimensional analysis, VB reinforcement program and VB optimization program. After studying the basic construction technology of traditional fixed tower crane foundation, Jiang and Wan designed a 60T prefabricated cross-shaped steel tower crane foundation composed of cross-shaped steel, bottom steel plate, frame plate, etc., and verified its safety and reliability. Chen studied the theory and application of prefabricated cross-shaped steel tower crane foundation in detail. Su and Tan conducted a mechanical analysis of foundation beams. Later, cross-shaped cast-in-place concrete foundations were developed based on different geological conditions. For example, Zhao developed the prefabricated concrete tower crane foundation (Zhao Shi tower crane). To address the above-mentioned challenges, various forms of foundations were developed. Take the conventional QTZ40 tower crane foundation (4.5×4.5×1.2 m) as an example, its total costs, including construction costs (more than 30,000 yuan) and costs for demolition and garbage removal, reach up to 60,000 yuan, resulting in waste of resources and environmental pollution. Also, it is only for one-time use and costs a lot. The use of cast-in-place concrete foundation by traditional tower cranes has problems such as large size, long construction cycle, and the tower crane can be installed with concrete of specified design strength after it is maintained for more than 7d following concrete pouring.
