Research on the Design and Construction Technology of the Combination of Tower Crane Foundation and Deep Foundation Pit Supporting Structure

Taking the Luohu Food Building project as an example, the design and construction technology of combining the tower crane foundation with the deep foundation pit support system is proposed. The technology expounds a kind of not outside the scope of the existing internal support structure to set up a high pile cap tower crane foundation alone, make full use of the deep foundation pit support structure system, so that the tower crane foundation and the deep foundation pit support structure system are combined, and finally complete the design and construction of the tower crane foundation and the deep foundation pit support system. Compared with the traditional technology of setting up the tower crane foundation separately outside the scope of the inner support structure, this technology not only reduces the cost of setting up the tower crane foundation of the high pile cap alone, but also effectively solves the problem of difficult vertical transportation during the construction of the foundation pit support structure, and has achieved good economic benefits and has greater promotion value.
