Abstract

The invention provides an annular plate support foundation pit supporting structure and a construction method thereof, and relates to the technical field of underground engineering. The annular platesupport foundation pit supporting structure comprises a first supporting pile, a second supporting pile, a ring crown beam and an annular plate support; lateral water and soil pressure at the periphery of a foundation pit is transferred to the annular plate support and the ring crown beam through the first supporting pile and the second supporting pile, and is converted to axial pressure of the annular plate support and the ring crown beam, so that the deformation of the foundation pit is controlled, and the pressure resistance of concrete is fully exerted; the shear force and the bending moment in the annular support plate and the ring crown beam are both lower, so that the stress form is more scientific; and the annular plate support and the ring crown beam annularly arranged around thefoundation pit have no need to reserve space for inner supports and stand columns thereof, so that an earthwork excavation working surface and a soil outlet channel of the foundation pit are arrangedon a plane and a vertical surface more easily, and the technical problem of a supporting structure in the prior art incapable of meeting the foundation pit operation demands under soft soil environments is relieved.

Description

technical field [0001] The invention relates to the technical field of underground engineering, in particular to an annular slab support foundation pit support structure and a construction method thereof, in particular to a support structure applied in a foundation pit under a soft soil environment and a construction method thereof. Background technique [0002] In recent years, with the rapid development of China's economy and the continuous advancement of urbanization, more and more land has been developed, and the underground space of buildings has been more and more widely used. The excavation of deep foundation pits in the city not only needs to ensure its own safety, but also requires ensuring that it does not cause harm to the surrounding environment. [0003] However, in the soft soil environment, the soil layer has the characteristics of high compressibility, large void ratio, and water saturation. It is difficult for single support technologies such as underground ...
