Problems solved by technology
[0002] In the prior art, the construction of steel pipe piles for offshore trestle bridges requires different construction methods according to the different geological conditions of the seabed. For areas with overburden layers, the pile driving hammer hammer pile method or the vibration pile sinking method is generally used. Areas in the area are generally stabilized by group piles. Steel pipe piles sit directly on the bedrock or a combination of bored piles and steel pipe piles is used. There is no mature construction method in areas with long lines

Embodiment Construction
[0022] Such as Figure 1 to Figure 4 As shown, the anchoring method of trestle steel pipe piles on the exposed seabed rock landform includes the following steps: A. Make the auxiliary platform for steel pipe piles and initially support the steel pipe piles. The support and positioning of steel pipe piles in the sea needs to be completed with the aid of the auxiliary positioning platform , the auxiliary positioning platform 1 can be leveled to be suitable for the ups and downs of the seabed, and the leveling is realized by telescopic outriggers. After the auxiliary positioning platform 1 is leveled, the limit pin on the small steel pipe is stuck on the clamping plate of the large steel pipe, thereby limiting the jumping of the small steel pipe and keeping the auxiliary positioning platform level. The steel pipe pile is hoisted by the crane for positioning and support. After the positioning is completed, it will be paralleled with other steel pipe piles that have been supported....

The invention discloses a method for anchoring trestle steel pipe piles on a seabed rock bare landform. The method includes the following steps that first, a steel pipe pile assisting platform is manufactured and steel pipe piles are preliminarily erected; second, concrete is poured in steel pipes underwater; third, holes are drilled in the concrete in the steel pipes, and the concrete is drilled through till a preset depth below the bed rock face is reached; fourth, anchor rods are placed in the drilled holes, and mortar is pressed in the drilled holes. The method for anchoring trestle steel pipe piles on the seabed rock bare landform solves the problem that steel pipe piles cannot be driven in the seabed rock bare landform through traditional hammering or vibration, achieves stable connection between the steel pipe piles and rock and has the advantages of being easy to operate, little in material consumption, stable, reliable and high in economic benefit.
Description
technical field [0001] The invention relates to an anchoring method for trestle steel pipe piles on exposed seabed rock landforms. Background technique [0002] In the prior art, the construction of steel pipe piles for offshore trestle bridges requires different construction methods according to the different geological conditions of the seabed. For areas with overburden layers, the pile driving hammer hammer pile method or the vibration pile sinking method is generally used. Areas in the area are generally stabilized by group piles. Steel pipe piles sit directly on the bedrock or a combination of bored piles and steel pipe piles is used. There is no mature construction method in areas with long lines. Contents of the invention [0003] The purpose of the present invention is to provide a method for anchoring steel pipe piles of trestle bridges on exposed seabed rock landforms. [0004] The technical solution adopted by the present invention to achieve the above object ...
