The invention provides a construction method of a soft soil layer foundation pit slope top tower crane foundation. The construction method comprises the steps that constructing support piles and a waterproof curtain; reinforcing the soil body on the periphery of the tower crane foundation; constructing a tower crane pile foundation; constructing crown beams and anchor cables or constructing crownbeams and supporting beams; constructing a tower crane foundation bearing platform on the foundation pit slope top and installing a tower crane body on the tower crane foundation bearing platform. Compared with the prior art, the construction method of the soft soil layer foundation pit slope top tower crane foundation has the beneficial effects that settlement deformation and horizontal displacement of the foundation can be effectively controlled, the construction speed is rapid, operation is convenient, standard components can be rapidly installed, and construction efficiency is greatly improved.
Description
Technical field [0001] The invention relates to the technical field of construction engineering, in particular, to a construction method of a tower crane foundation on a slope top of a foundation pit in a soft soil layer. Background technique [0002] At present, in areas with deep soft soils in rivers and coastal alluvial areas, the construction of deep foundation pits and basements in urban construction projects often requires the cooperation of tower cranes to provide construction efficiency and progress. The tower crane foundation of a deep foundation pit is usually set in the basement structure area of the foundation pit, or the tower crane foundation is set on the basement floor at the bottom of the foundation pit, or the tower crane foundation is set on the ground by using pile foundations and steel lattice column members. Therefore, in order to speed up the progress of the project and coordinate with the horizontal and vertical transportation of the project, it is often...
