In the construction of deep-water pile foundations, steel casings are required, and the two steel casings need to be docked. When the two steel casings are installed and docked, bolts are used to fix them, and the butt holes on the two steel casings need to be connected. Align the positions, and then install the bolts. Due to the large size of the steel casing, it is more troublesome to adjust the hole position, which leads to time-consuming and laborious for the user, and it is more troublesome to disassemble. In addition, when the existing part is installed and docked with the two steel casings , its butt joint seal is not good, resulting in poor butt joint effect

The invention discloses an assembly type clamping structure of a deepwater pile foundation construction steel casing. The assembly type clamping structure comprises a steel casing body, and a butt joint component is arranged on the steel casing body; the fixing mechanism comprises a fixing cylinder and a clamping part, the fixing cylinder is fixedly arranged on the outer surface of the steel casing body in a sleeving mode, the clamping part is arranged in the fixing cylinder, a fixing gear ring drives a connecting plate and a fixing rod to rotate by rotating a fixing handle, when the fixing rod rotates to a proper position, the steel casing body is in butt joint, the fixing rod is inserted into the fixing cylinder at the moment, and the steel casing body is fixed. Two first two-way threaded rods can rotate through transmission of a connecting synchronous wheel, two clamping rods get close to each other, a user can conveniently disassemble and assemble the steel casing bodies, meanwhile, alignment is facilitated, and therefore the two steel casing bodies can be in butt joint rapidly; therefore, the connecting effect of the connecting pipe and the butt joint pipe is improved, and the sealing performance is improved.
Description
technical field [0001] The invention belongs to the technical field of technical steel protective tube installation, in particular to an assembled clamping structure of a steel protective tube for deep-water pile foundation construction. Background technique [0002] Steel casing is in the process of manual digging of hole piles. Due to unstable soil conditions, it is difficult to construct reinforced concrete retaining walls. Therefore, steel retaining walls are used to protect the hole piles to prevent hole collapse and avoid affecting the construction progress and safety. The steel casing is a circular barrel with empty ends formed by iron sheets according to the size of the hole pile. The function of the steel casing is to stabilize the hole wall, prevent the hole from collapsing, and can also isolate the surface water, guide the drill bit, and fix it. Pile position, protect the original ground for operation, etc. [0003] In the construction of deep-water pile foundati...
