Sea foundation pile anti-drawing testing device and testing method thereof

Abstract

The invention relates to a sea foundation pile anti-drawing testing device and a testing method thereof. The sea foundation pile anti-drawing testing device comprises a foundation pile located in the middle and platform ships located on the two sides of the foundation pile, and the upper end of the foundation pile is movably connected with the middle position of a transversely-arranged counter-force beam; the two ends of the counter-force beam are hinged to the middle positions of large balance beams located below the counter-force beam, and the large balance beams are perpendicular to the counter-force beam; the two ends of each large balance beam are hinged to the middle positions of small balance beams below the large balance beam, and the small balance beams are perpendicular to the large balance beams; supporting bases are hinged to the two ends of each small balance beam; and a jack abutting against the supporting bases on the corresponding side is arranged on the corresponding platform ship. According to the sea foundation pile anti-drawing testing device and the testing method, the problems existing in operation platforms and the problem that a sea counter-force support is difficult to find are directly solved; the problems that a large amount of manpower, a large number of material resources and a large amount of time need to be spent in a sea large-diameter pile anti-drawing test and an anchor pile needs to be specially arranged are solved; and the on-site detecting efficiency and the economical efficiency are greatly improved.

Description

technical field [0001] The invention relates to an offshore foundation pile pullout test device and a test method thereof. Background technique [0002] Vertical uplift static load test of foundation pile is to use the test close to the actual working conditions of vertical uplift pile to determine the ultimate bearing capacity of single pile vertical uplift resistance. The main purpose of single pile vertical uplift static load test includes the following three aspects: [0003] 1. Determine the ultimate vertical bearing capacity of the single pile and the characteristic value of the vertical bearing capacity of the single pile; [0004] 2. Determine whether the vertical uplift bearing capacity meets the design requirements; [0005] 3. When the pile body stress and strain measuring elements are buried, the uplift friction resistance of each soil layer around the pile can be measured. [0006] The pull-out test needs to provide a reaction force device, and the reaction f...

AI Technical Summary

Problems solved by technology

[0009] 1. It is difficult to find the reaction force support required for the pull-out test of offshore foundation piles. If the anchor pile is specially designed for the test, this method is not only time-consuming and laborious, but also economical;

[0010] 2. A platform is required for operations at sea, and the lack of an operation platform brings certain difficulties to the construction
