AI Technical Summary

Technical Problem

In deep foundation pit projects, it is difficult to quickly meet the requirements of the bearing capacity of the construction elevator foundation after earthwork is backfilled, resulting in impact on the construction progress and uneven settlement of the elevator foundation, causing safety hazards.

Method used

Design a foundation support structure for the construction of a deep foundation pit, including setting up support ox legs on the basement exterior wall and setting up support frames in the deep foundation pit. The foundation of the construction elevator is supported on the support ox legs and support frames to form effective rigid support.

Benefits of technology

It has achieved the requirement of meeting the foundation bearing capacity required for construction elevators in a short time, avoiding safety hazards caused by uneven settlement, and ensuring construction progress and safety.

Abstract

A deep foundation pit construction elevator foundation supporting structure comprises a basement outer wall, a deep foundation pit excavated on the outer side of the basement outer wall and a construction elevator foundation horizontally arranged, and is characterized in that a supporting bracket is arranged on the basement outer wall, a supporting frame is arranged in the deep foundation pit, and the construction elevator foundation is supported on the supporting bracket and the supporting frame; the supporting bracket is close to the inner end of the construction elevator foundation, the supporting frame is close to the outer end of the construction elevator foundation, and the supporting bracket and the supporting frame are arranged in parallel in the length direction of the construction elevator foundation. The requirement for the foundation bearing capacity needed by the construction elevator is met in a short time, it can be guaranteed that rapid construction can be achieved after earthwork backfilling, the construction progress is not affected, potential safety hazards caused by differential settlement of a construction elevator foundation can be avoided, safety and practicability are achieved, and the use safety of the construction elevator is improved.
