Abstract

The invention belongs to the technical field of foundation pit supporting, and discloses a construction method of a supporting structure in a large-span foundation pit. The problem that an existing anti-floating anchor rod is poor in bearing capacity on a soft stratum is solved. Compared with the prior art, the construction amount of supports in the large foundation pit can be saved on the premise that the stability of the large-span foundation pit support is guaranteed; meanwhile, according to the beneficial characteristics of the periphery of the foundation pit, a single large span is adopted for supporting, and later-period main structure construction is prevented from being affected; and the usage amount of concrete and steel bars is reduced, the construction period is shortened, the construction cost is reduced, and the development direction of green deep foundation pits is met.

Description

technical field [0001] The invention belongs to the technical field of foundation pit support, and in particular relates to a construction method for a support structure in a large-span foundation pit. Background technique [0002] A foundation pit is a space dug downward from the ground for the construction of the underground part of a building (structure). Usually, the surrounding environment of the foundation pit is relatively complex, such as adjacent to municipal roads, subways, high-rise buildings, etc., which need to be protected, so the deformation and stability during the excavation process of the foundation pit must be strictly controlled. [0003] Internal support is a support measure that can effectively control the deformation of the foundation pit in the foundation pit support, and is widely used in deep and large foundation pits that require deformation control. The main advantages of conventional internal support: ① Take advantage of the material. ②Speed ​​...
