Abstract

The invention provides a recoverable and modular deep foundation pit construction process, a recoverable module and a deep foundation pit support and belongs to the technical field of deep foundation pit excavation and supporting. The process comprises the following steps that a foundation pit is dug down; a first anchor cable hole is formed, a first anchor cable is put in, and a grouting stop plug is installed for grouting; a second anchor cable hole is formed, a second anchor cable is put in, and a grouting stop plug is installed for grouting; modules and connecting fasteners are installed; a prestressing force is exerted to the first anchor cable and the second anchor cable to for a first layer of supporting; the operations are repeated to form multiple layers of supporting; modules, anchor cables and connecting fasteners of the last layer of supporting are recovered, soil is backfilled to the bottom surface of the second layer of supporting till the first layer of supporting is recovered. A soil body surrounding a deep foundation pit is supported and retained by adopting the modules and anchor cables jointly, the modules can be recycled, and materials waste and construction cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of deep foundation pit excavation and support, and more specifically relates to a recyclable modular deep foundation pit construction technology, a recyclable module used in the construction technology and deep foundation pit support. Background technique [0002] In construction projects, due to the depth of buildings and the use of underground garages, equipment rooms, and underground space, it is often necessary to excavate the soil. In order to ensure the construction of surrounding buildings, roads, pipelines, and foundation pits during excavation In order to ensure the safety of the foundation pit, it is necessary to support the soil outside the excavation range to ensure the safety of the foundation pit. At present, most of the support and retaining systems use disposable piles, soil nail walls or a combination of the two. After the foundation pit is backfilled, it loses its function. Because it is no...
