[0004] However, in the centrifugal model test, the pile needs to be statically installed into the seabed soil at first. At present, the jack is usually used to press in directly. Experimental error, even if there are some devices that can control its verticality, it cannot be applied to the situation of different pile diameters

The invention discloses a pile verticality control penetrating device for pile foundation centrifugal test, which comprises a model pile, a loading penetrating system, a verticality control system and a centrifuge model box. The verticality control system includes a fixed upper plate and a fixed lower plate arranged in parallel, both of which are ring-shaped plates, and the model pile is located at the center of the ring-shaped plate; there are 4 holes in the radial direction on the fixed upper plate. There is also a guide groove on the corresponding position of the fixed lower plate and the fixed upper plate, which is used to provide constraints for the guide plate; the upper and lower ends of the guide plate are located in the guide groove, and can be moved along the diameter To adapt to the installation requirements of different pile diameters. Through this device, the pile foundation can be penetrated into the seabed soil, and the distance between the guide plates can be changed to suit the pressure piles of different pile diameters, and the verticality of the pressure piles can be guaranteed during the penetration process to meet the later test and test Require.
Description
technical field [0001] The invention belongs to the technical field of centrifugal tests, and in particular relates to a penetrating device for controlling verticality of piles used in centrifugal tests of pile foundations. Through this device, the pile foundation can be penetrated into the seabed soil, and the distance between the guide plates can be changed to suit the pressure piles of different pile diameters, and the verticality of the pressure piles can be ensured during the penetration process to meet the later test and test Require. Background technique [0002] As an important foundation type, offshore pile foundation is installed on the surface of the seabed by driving or static pressure penetration to support the upper structure, such as offshore wind turbines, fixed offshore oil and gas platforms, etc. At present, this foundation type occupies an important position in the foundation form of shallow ocean structures. [0003] In order to explore the bearing capa...
