Embodiment 1

[0044] Such as Figure 1-7 The excavation and depth protection structure shown in the foundation pit includes two symmetrical support columns 2 fixedly connected to the inner wall of the bottom of the foundation pit 1 by bolts. Guard plate 3, the top of support column 2 is fixedly connected with cross bar 4 by bolt, and the top of cross bar 4 is connected with drive motor 5 by bolt, and the top of cross bar 4 is connected with protective cover 37 by bolt, and drive motor 5 Located in the protective cover 37, the drive motor 5 can be protected by the protective cover 37 to avoid damage to the drive motor 5 in the construction process. The horizontal bar 4 is longitudinally rotated and connected with a rotating shaft 7, and the outer wall of the rotating shaft 7 is fixed. The sleeve is provided with a first The bevel gear 8, the output shaft of the drive motor 5 extends into the cross bar 4 and is fixedly connected with the top of the rotating shaft 7 through a coupling. The cro...

Embodiment 2

[0052] This embodiment is a further improvement of the previous embodiment, such as Figure 1-9 As shown, a foundation pit enclosure structure that can be excavated while maintaining depth includes two symmetrical support columns 2 that are fixedly connected to the inner wall of the bottom of the foundation pit 1 by bolts. Guard plate 3, the top of support column 2 is fixedly connected with cross bar 4 by bolt, and the top of cross bar 4 is connected with drive motor 5 by bolt, and the top of cross bar 4 is connected with protective cover 37 by bolt, and drive motor 5 Located in the protective cover 37, the drive motor 5 can be protected by the protective cover 37 to avoid damage to the drive motor 5 in the construction process. The horizontal bar 4 is longitudinally rotated and connected with a rotating shaft 7, and the outer wall of the rotating shaft 7 is fixed. The sleeve is provided with a first The bevel gear 8, the output shaft of the drive motor 5 extends into the cros...

Abstract

The foundation pit support structure comprises two symmetrical supporting columns fixedly connected to the inner wall of the bottom of a foundation pit, support plates are arranged on the inner walls of the sides, away from each other, of the foundation pit, a transverse rod is fixedly connected to the tops of the supporting columns through bolts, and a driving motor is fixedly connected to the top of the transverse rod; a first bevel gear fixedly sleeves the outer wall of the rotating shaft in the transverse rod, an output shaft of the driving motor extends into the transverse rod and is fixedly connected with the top end of the rotating shaft, two first enclosure assemblies used for enclosing a foundation pit are arranged in the transverse rod, a rectangular through hole is formed in the top end of the supporting column, and a circular ring is fixedly embedded in the inner wall of the bottom of the transverse rod; the bottom end of the rotating shaft rotationally penetrates through the circular ring and is fixedly connected with a straight gear, and two second enclosure assemblies used for enclosing the foundation pit are arranged at the bottom of the transverse rod. The problems that in the prior art, an enclosure structure is poor in recoverability, supporting cannot be conducted according to deformation of a foundation pit, and the deformation degree of the foundation pit cannot be monitored in real time are solved.

Description

technical field [0001] The invention belongs to the technical field of foundation pit enclosure, and relates to a deep foundation pit enclosure structure and a support method thereof. Background technique [0002] In urban centers with dense buildings, the excavation of deep foundation pits has become an important subject in geotechnical engineering. The foundation pit enclosure system is an organic body that interacts with soil and support structures. Due to the constraints of surrounding buildings and underground pipelines, there are higher requirements for the safety of the foundation pit enclosure system. The enclosure of the foundation pit not only ensures the stability of the foundation pit and the safety and convenience of the operation in the pit, but also controls the displacement of the soil at the bottom of the pit and outside the pit within a certain range to ensure the normal use of adjacent buildings and municipal facilities. [0003] The foundation pit enclos...
