Embodiment Construction
[0024] Such as Figure 1-3 A steel pipe anchoring construction device for deep water and shallow overburden is shown, including a steel pipe 2 inserted into hard rock 5, and holes are opened at 5 places where hard rock is exposed on the steel pipe 2, and angle steel 9 is arranged in the hole in order to reinforce the steel pipe 2. In the embodiment, each steel pipe 2 is provided with four holes equidistantly along the circumferential direction, and an angle steel 9 is arranged in each hole. The positional relationship of the four holes makes the four angle steels located at the four vertices of the square. A sandbag 1 is arranged around the hole on the steel pipe 2. The hard rock 5 has just been exposed in the hole. The sandbag 1 is thrown on the hard rock 5. The steel pipe 2 is poured with concrete 7. The steel pipe 2 is welded to a position above the low tide water level 4. The double channel steel 3 that lives hard rock 5, the top of steel pipe 2 is provided with operating...

The invention provides a deepwater shallow covering layer steel pipe anchoring construction device and method. The deepwater shallow covering layer steel pipe anchoring construction device comprises steel pipes inserted into hard rock, holes are formed in the positions, exposed out of the hard rock, of the steel pipes, angle steel is arranged in the holes, sandbags are arranged around the holes inthe steel pipes, the steel pipes are filled with concrete, double-spliced channel steel with one end abutting against the hard rock is welded to the position, above the low tide water level, of eachsteel pipe, and an operation platform is arranged at the top ends of the steel pipes. According to the deepwater shallow covering layer steel pipe anchoring construction device and method, the steel pipes are supported underwater through the double-spliced channel steel channel and the sandbags, the steel pipes are connected into a matrix through steel cables, then the steel pipe matrix is anchored in the underwater hard rock through concrete pouring, pipe pile anchoring is easy and convenient, meanwhile, the stability of the steel pipes is effectively controlled, the construction operation speed is increased, the quality is guaranteed, and the construction progress of a trestle is accelerated.
Description
technical field [0001] The invention belongs to the technical field of trestle construction over water, and more specifically relates to a construction device and method for anchoring steel pipes in deep water and shallow covering layers. Background technique [0002] During the construction of sea-crossing and river-crossing bridges, hard rock geology in deep water and shallow overburden is often encountered. During the construction of temporary steel trestle bridges, in order to ensure the bearing capacity and stability of steel pipe piles, methods such as full-section gravity, bench piles, and steel pipe ring cutting are mostly used. The full-section gravity type is to first link multiple steel pipes on the shore site by relying on the bottom concrete to form a whole, and then hoist them to the design position with lifting equipment, and provide stability to the steel pipe piles through the overall gravity; bench-type steel pipe piles Relying on hard rock to provide bear...
