Problems solved by technology

[0003] Aiming at the problems of how to lay a stable foundation in sand and gravel in existing projects, a visual test device and method for coral sand breakage around piles with adjustable lateral stiffness are proposed. Under the limited pressure, the specific situation of coral sand breaking and displacement in the piling process, simulate the piling in the sand and gravel under actual conditions, the stress and damage of the sand and gravel, and then according to the data research, how to lay a stable foundation. conclusion of the question

Abstract

The invention provides a visual test device and method for crushing coral sand around a pile in a pile sinking process. The device comprises a cuboid test box. A top cover is fixed at the top of the cuboid test box. Two paired side walls of the cuboid test box are movable plates, jacks for applying pressure to the movable plates are arranged on the outer sides of the movable plates, windows are formed in the side walls of the movable plates, and cameras for recording the test process are arranged at different heights of the windows and the precast pile respectively. During a test, a precast pile is arranged in the cuboid test box, a plurality of coral sand layers are filled and laid in the cuboid test box, and pressure sensing pieces are arranged on the same plane of the coral sand layersat equal intervals in the transverse direction and the radial direction.

Description

technical field [0001] The invention relates to the technical field of broken coral sand around piles during pile sinking construction, and mainly relates to a visual test device and method for broken coral sand around piles during pile sinking. Background technique [0002] With the needs of national defense construction and the development and utilization of marine oil and gas, fishery, tourism and other resources, the number and scale of coral island and reef construction projects are increasing day by day, and the demand for piling in coral sand is also increasing. Pile sinking is a widely applicable way to strengthen the foundation on land, but it faces great difficulties in the construction of islands and reefs. The main components of coral reef foundations are coral sand, reef limestone, calcareous soil, and coral clastic soil. Among them, coral sand (also known as calcareous sand) has loose particles, high porosity, large apparent friction angle, and is easily broken...
