Abstract

Abstract:

A new technology for dismantling of the concrete waling of deep foundation pits is adopted in order to protect the surrounding environment, to guarantee the safety of the nearby buildings and labors and to control the deformation of the foundation pits after waling dismantling. The practice shows that the core drilling method used in the dismantling of the concrete waling can improve the safety and reliability of the dismantling operation, can reduce the dismantling cost and can improve the dismantling efficiency.

Key words: deep foundation pit, intercity rail transit, cutandcover tunnel, underground station, concrete waling, core drill, dismantling
