Therefore, when performing pit-in-pit formwork concrete construction, the operator can evenly apply reaction force through the pile reaction force anti-floating device and transmit it to various parts of the formwork and the support frame as a whole, ensuring that the formwork and the support frame are not skewed, floated, or deformed. The invention solves the problems in the prior art of the pit-in-pit formwork construction method that the piled objects are easy to collapse and the formwork cannot be kept from deforming during the pouring process, resulting in poor molding quality, concrete joint defects and hidden dangers of water seepage, ensures the safety and quality of the construction, and avoids the construction inconvenience and cost increase caused by multiple layered pouring in the traditional method.

[0021] In a specific implementation, the distribution layer 30 is used to evenly transfer the reaction force generated by the pile reaction anti-floating device 40 to the template structure 10 and the support frame 20 .

[0022] Specifically, Figure 2As shown, the formwork structure 10 is arranged above the steel frame, including a horizontal bottom formwork 11 and a vertical side formwork 12; the horizontal bottom formwork 11 is composed of multiple pieces, which are laid along the top of the steel frame to form the bottom formwork of the elevator shaft; the vertical side formwork 12 is composed of multiple pieces, which are enclosed along the circumference of the horizontal bottom formwork 11 to form a closed structure to form the vertical side wall formwork of the elevator shaft, and the horizontal bottom formwork 11 and the vertical side formwork 12 are respectively strengthened and made into bending-resistant components for on-site assembly, so that the formwork is easy to disassemble and assemble, and during the concrete pouring process, the formwork structure 10 can effectively resist the effect of buoyancy and maintain the structural shape of the elevator shaft.
