Embodiment 1
[0020] Such as figure 1 , figure 2 As shown, a hydraulic jacking correction system in the final sinking stage of caissons, the construction steps are as follows:
[0021] 1) Before the prefabrication of the well body 1, the cast-in-situ piles 2 are first constructed on the four inner sides of the well wall, the elevation of the pile top is controlled to 0.5 meters below the bottom of the final sinking shaft, and the steel lattice columns 3 are inserted, and the steel lattice columns 3 are inserted into the pouring Pile 2 is 2 meters inside and 1 meter outside;
[0022] 2) Prefabricated caissons in sections, a cast-in-place corbel 13 is installed at the bottom of the inner side of the first shaft 1, excavation is carried out when the strength of the cast-in-place pile 2 in the lower part meets the requirements, and the caisson operation is carried out;
[0023] 3) When the well body 1 sinks to near the final sinking elevation, first weld the steel lattice column 3 and the pr...
Embodiment 2
[0029] Such as figure 1 , figure 2 As shown, a hydraulic jacking correction system in the final sinking stage of caissons, the construction steps are as follows:
[0030] 1) Before the prefabrication of the well body 1, the cast-in-situ piles 2 are first constructed on the four inner sides of the well wall, the elevation of the pile top is controlled to 0.5 meters below the bottom of the final sinking shaft, and the steel lattice columns 3 are inserted, and the steel lattice columns 3 are inserted into the pouring Pile 2 is 2 meters inside and 1 meter outside;
[0031] 2) Prefabricated caissons in sections, a cast-in-place corbel 13 is installed at the bottom of the inner side of the first shaft 1, excavation is carried out when the strength of the cast-in-place pile 2 in the lower part meets the requirements, and the caisson operation is carried out;
[0032] 3) When the well body 1 sinks to near the final sinking elevation, first weld the steel lattice column 3 and the pr...
