Description

Technical Field

[0001] This application relates to the technical field of foundation pit support, and in particular to a support structure for deep foundation pit construction of subway stations. Background Technology

[0002] A subway station is an underground urban rapid transit system. It's a mode of transportation that utilizes underground roads and operates on a track-separated system, aiming to provide efficient, fast, and convenient urban transportation services. The standard construction sequence for the open-cut method is to construct the subbase, sidewalls, and roof slab after excavating to the predetermined depth; this is the standard construction method for the open-cut method.

[0003] Deep foundation pit engineering is characterized by complex soil conditions, poor slope stability, complex underground facilities, tight construction schedules, limited construction sites, high engineering risks, and stringent environmental protection requirements. Existing support structures for deep foundation pits typically employ methods such as diaphragm walls and pile banks, lacking reinforcement of the internal support structure. Therefore, to address these issues, this application provides a support structure for deep foundation pit construction in subway stations. Utility Model Content

[0004] To address the aforementioned problems, this application provides a support structure for deep foundation pit construction in subway stations.

[0005] This application provides a support structure for the construction of deep foundation pits in subway stations, including a support plate. A side beam is fixedly installed on one side of the support plate inside the foundation pit, and a crossbeam is installed between the side beams. An adjustment component is installed between the two crossbeams to apply prestress to the position of the crossbeam.

[0006] By setting side beams on the inner side of the support plate and vertically installing crossbeams on the side beams, and setting adjustment components between the crossbeams to adjust the prestress, a good support effect for the foundation pit can be achieved.

[0007] Preferably, angle iron brackets are installed on the side walls of the support plate, and the angle iron brackets and the side beams are bolted together.

[0008] Preferably, the crossbeams are provided in two sets, and each set of crossbeams is provided with two beams, with the two beams in each set connected by an adjusting component.

[0009] Preferably, the adjusting component is a jack.

[0010] Preferably, each of the crossbeams and side beams is provided with a diagonal bracing beam, and the diagonal bracing beams are fixedly connected to the crossbeams and side beams by bolts.

[0011] Preferably, a connecting beam is provided between each of the two sets of crossbeams.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By setting side beams on the inner side of the support plate and vertically installing crossbeams on the side beams, and setting adjustment components between the crossbeams to adjust the prestress, a good support effect for the foundation pit can be achieved. Attached Figure Description
