Description

Technical Field

[0001] The invention relates to the technical field of water transport engineering, and in particular to a quick pile clamping system and a construction method for pile cap foundation piles of an offshore wharf. Background Art

[0002] In the construction of high-pile docks, pile clamping is a key construction link, which is directly related to the quality and safety of the project. The design of the pile clamping must ensure sufficient strength and stability to withstand various horizontal loads such as strong winds and waves, large currents, etc. without causing the pile body to deviate.

[0003] The traditional pile clamping structure adopts a "calf leg + channel steel" well-shaped structure. First, the main beam channel steel is hoisted to the welded corbels on both sides of the steel pipe pile or the corbels attached to the hoop are fully welded, and then the secondary beam channel steel in the vertical direction is close to the two sides of the steel pipe pile to form a well-shaped overall force. There is also a method of directly welding two by two on the top of the steel pipe pile with steel sections to make the steel pipe pile form a whole. However, under the environmental conditions of high frequency of strong winds and waves at sea and large tidal range, the "calf leg + channel steel" well-shaped structure is adopted, and the pile clamping speed is slow; the method of directly welding two by two on the top of the steel pipe pile with steel sections lacks an operating platform and has a greater safety risk. If a ship is used as an operating platform, it is affected by the tidal range and the work efficiency is very low. After the pile is sunk, if the pile cannot be clamped quickly, it is very likely that the steel pipe pile has been deviated before the pile clamping is completed. Therefore, the above-mentioned pile clamping structure has the problems of complex pile clamping process, low work efficiency, and poor adaptability to offshore construction.

[0004] Chinese utility model patent CN220246920U (publication date: December 26, 2023) discloses a steel pipe pile clamping structure, the installation of the structural steel clamp can be performed immediately after the current pile is sunk, without delaying the subsequent pile sinking. Therefore, the construction process of the pile clamping part can be synchronized with the pile sinking, thereby improving construction efficiency.

[0005] Although the above patents have improved the construction efficiency to a certain extent, they have not solved the problems of complicated pile clamping technology and poor adaptability to offshore construction. Considering the large tidal range and frequent strong winds and waves at sea, an operating platform is needed to connect the steel pipe piles in pairs to form a whole to achieve rapid pile clamping. In view of this, the present invention innovatively provides a rapid pile clamping system and construction method for offshore wharf pile cap foundation piles. Summary of the invention

[0006] The purpose of the present invention is to overcome the problems of the existing pile clamping process being complicated, low in efficiency, and unable to work in an offshore environment with a large tidal range and frequent strong winds and waves, and to provide a rapid pile clamping system and construction method for offshore wharf pile cap foundation piles. The method can reduce the safety risks existing in the pile clamping construction, protect the steel pipe piles from being displaced in the offshore environment, and realize rapid pile clamping.

The frame system is erected above the corbel to bear the construction load and reduce the shaking amplitude of the top of the steel pipe pile, thereby reducing the occurrence of deviation. The corbel in the present application is different from the load-bearing corbel used in the general pile clamp system. The corbel in the present application only bears the gravity of the operating platform and the workers on the platform, and has a very small weight. It is a small and light corbel.

[0010] The clamp pile connection system connects a plurality of steel pipe piles in pairs into a whole.

[0011] Furthermore, the number of the hoops is equal to the number of steel pipe piles, and each hoop includes two semicircular steel plates and a fastener. The concave arc surfaces of the two semicircular steel plates are arranged opposite to each other and are located on the same outer peripheral surface of the steel pipe pile. The same end of the steel plate extends outward perpendicular to the end surface of the steel plate to form a corbel; the fastener is used to fix the two semicircular steel plates.

[0012] Furthermore, the frame system includes a frame and a plurality of connecting rods; the connecting rods are connected to the frame via bolts.

[0013] Furthermore, the pile clamp connection system has a plurality of support rods, which connect the steel pipe piles in pairs into a whole.

[0014] Furthermore, wooden boards are laid above the frame and the connecting rods.

[0015] Furthermore, a construction method of a rapid pile clamping system for an offshore wharf pile cap foundation pile is characterized by comprising the following steps:

[0016] S1. Make a hoop and fix it on the steel pipe pile with the corbel extending outward;

[0017] S2. Make a frame system: make a frame and a connecting rod, connect the frame and the connecting rod into one with bolts, and lay and fix the wooden board on the frame;

[0018] S3, erect the frame system on top of the corbel;

[0019] S4. The operator welds and fixes the support rods and steel pipe piles in pairs on the frame system;

[0020] S5. Remove the wooden boards, unscrew the bolts, take out the frame and connecting rods, and reuse them for other construction.
