Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit steel sheet piles, in particular to a supporting device for foundation pit steel sheet piles. Background Art

[0002] Foundation pits are very common in the construction field. Steel sheet piles are installed on the inner wall of the foundation pit. The steel sheet piles play a waterproof role. Since the foundation pit is lower than the ground, steel sheet piles are needed to prevent water from entering the foundation pit. In order to make the steel sheet piles more stable and not tilted, a support device is needed to support them. After searching, the patent document with the publication (announcement) number: CN217325399U provides a support device for foundation pit steel sheet piles, including a first maintenance plate, a second maintenance plate and a transverse support rod. The support plate is installed on the inner side of the first maintenance plate, and the second maintenance plate is symmetrically installed on one side of the first maintenance plate, and the inner side of the second maintenance plate is connected to one side of the support plate.

A mounting plate is installed inside the longitudinal support rod, and a telescopic spring is installed on one side of the mounting plate, and a limit plate is installed at one end of the telescopic spring. When the support rod is installed, the telescopic head will be retracted into the inside of the support rod under pressure, and the other end will be squeezed into another support groove through the installation head, so that the support device can be installed. If disassembly is required, impact force is applied to the support rod from bottom to top, which will cause the support rod to be disassembled, which is very convenient.
