Overwater steel pipe pile bearing capacity detection device and construction method

Abstract

The invention belongs to the technical field of civil engineering construction, and particularly relates to a construction method of an overwater steel pipe pile bearing capacity detection device. Theoverwater steel pipe pile bearing capacity detection device comprises at least three buoyancy air bags uniformly arranged around a steel pipe pile, a bearing platform is arranged on the buoyancy airbags, the bearing platform is higher than the top of the steel pipe pile, and a force transmission structure is arranged between the top of the steel pipe pile and the bearing platform. A dynamometeris arranged at the top of the force transmission structure. The overwater steel pipe pile bearing capacity detection device further comprises a displacement sensor, the actual bearing capacity calculated through the numerical value measured by the dynamometer is compared with the theoretically calculated ultimate bearing capacity standard value, and whether the steel pipe pile can be safely constructed or not is judged. The overwater steel pipe pile bearing capacity detection device is simple in structure, can visually perform detection, is simple and convenient in construction operation, andcan effectively detect the actual limit side friction resistance.

Description

technical field [0001] The invention belongs to the technical field of civil engineering construction, and in particular relates to a bearing capacity detection device and construction method of steel pipe piles on water. Background technique [0002] Pile side friction is used as the core problem of pile foundation design, and its bearing capacity is mainly borne by pile side friction. In existing designs, pile side friction is calculated. However, in practical applications, due to the environment The impact of pile side friction is obvious, especially the side friction of offshore steel pipe piles, which is difficult to obtain from theory. If it is only calculated, it will seriously affect the bearing force of the steel pipe pile, making the construction safety poor. Contents of the invention [0003] The object of the present invention is to provide a test device and construction method for the bearing capacity of steel pipe piles on water, so as to solve the problem t...
