Embodiment Construction
[0061] Such as figure 1 Shown, a kind of caisson sinking construction method of the present invention comprises the steps:
[0062] (1) Foundation Pit Excavation
[0063] Such as figure 2 Shown is the schematic diagram of the structure of the foundation pit,
[0064] (1) In order to reduce the engineering quantity of caisson sinking, the foundation pit is excavated at the caisson fabrication site. The excavation depth of the foundation pit is determined according to the site soil quality and environmental conditions, so as to ensure that the caisson is 1m above the groundwater level during caisson fabrication. The size of the outer edge of the foundation pit is larger than that of the caisson to ensure that sufficient space for construction operations is reserved, such as the erection range of external scaffolding, some material storage yards and handling channels, crane and pump truck erection positions, etc.
[0065] (2) Drainage ditches and water collection wells are dug ...
