Device for monitoring deformation of steel plate pile surrounding structure in real time

Abstract

The invention belongs to the field of engineering design, and in particular, relates to a device for monitoring deformation of a steel plate pile surrounding structure in real time. The device comprises upper and lower parallel support steel pipes connected with a steel plate pile; a fixed pulley device is arranged below the upper support steel pipe, and includes a fixed pulley I and a fixed pulley II, wherein the fixed pulley I is mounted below the upper support steel pipe, and the fixed pulley II is mounted in the middle position below the upper support steel pipe; the fixed pulley I and the fixed pulley II are connected through a steel wire rope; a lifting hammer is connected below the steel wire rope bypassed through the fixed pulley II, and is put on a dial indicator; the dial indicator is connected with a data display instrument; the data display instrument is put on a support welded below the upper support steel pipe; the steel plate pile between the upper and lower parallel support steel pipes is welded with a reinforcement; and the steel wire rope bypassed through the fixed pulley I is fixed on the reinforcement. The device is simple in structure, can monitor the steel plate pile in real time, and guarantees the construction safety.

Description

technical field [0001] The invention belongs to the field of engineering design, in particular to a device for monitoring the deformation of a steel sheet pile enclosure structure. Background technique [0002] In the excavation and enclosure engineering of deep foundation pits, steel sheet piles are widely used in deep foundation pits due to their high strength, tight connection between piles, good water isolation effect, and reusable advantages. The steel sheet pile enclosure structure of deep foundation pit usually has multiple supports. The deformation of the steel sheet pile is relatively small at the supporting steel pipe, but the deformation of the steel sheet pile between the upper and lower supporting steel pipes is relatively large, and the phenomenon of "bulging belly" is prone to occur. Water leakage will lead to the overall instability and collapse of the steel sheet pile enclosure in severe cases, causing engineering accidents and threatening the personal saf...
