Problems solved by technology
The mobile platforms used in traditional offshore geological surveys are all pile-leg platforms, but when the shallow soil layer on the seabed is soft soil, the migration of the pile-leg platforms is inconvenient, and the cost of mobile platforms suitable for deep water areas is high
Simple fixed platform is less efficient and more expensive

Embodiment Construction
[0024] The present invention is described below in conjunction with accompanying drawing.
[0025] Such as figure 1 , figure 2 with image 3 As shown, an assembled cylindrical foundation offshore geological exploration platform structure consists of three foundation cylinders 1, three horizontal connecting rods 2, three vertical oblique connecting rods 3, an upper platform 4, a drilling casing 5 and a drilling casing The upper end of each base cylinder is provided with a top cover plate 6, and the lower end is open. On the top cover plate of each cylinder or on the upper end of the cylinder wall, there are ventilation and suction holes 7 with cut-off doors. On the top cover of each cylinder The middle part of the board is provided with a connecting joint 8; the horizontal connecting rod 3 and the vertical connecting rod 4 are round pipes with joints at both ends, and the three basic tubes 1 are arranged in an equilateral triangle, and three horizontal connecting rods are pa...

The invention discloses an assembled cylindrical foundation offshore geological exploration platform structure, which comprises foundation cylinders, horizontal connecting rods, vertical inclined connecting rods, an upper platform, a drilling protection cylinder and a drilling protection cylinder support member; the three foundation cylinders are in triangle arrangement and are connected by the three horizontal rods to form a whole; the drilling protection cylinder support member is connected to the tops of the foundation cylinders; the drilling protection cylinder is vertically erected on thedrilling protection cylinder support member; the upper platform is located at the top of the drilling protection cylinder; and the three vertical inclined connecting rods are used to connect the topsof the three foundation cylinders to the upper platform to form a whole. The structure disclosed by the invention has the beneficial effects that the platform structure can be detached and assembled,and the structure is convenient for long-distance transportation; and the wind-proof capability of the platform in use is strong, the platform is convenient to move, the construction and use costs are low, and the structure is suitable for deep waters.
Description
technical field [0001] The invention belongs to the field of facilities in the field of geological survey in coastal engineering, port engineering, offshore wind power engineering, offshore bridge and tunnel engineering, and in particular relates to an assembled cylindrical foundation platform structure that is convenient for assembly, disassembly and long-distance transportation, and is used for Offshore geological exploration. Background technique [0002] Offshore geological exploration usually uses ships or mobile platforms as working platforms. Ships will be affected by wind, waves and currents, and the working hours will be short. In the open sea, only mobile platforms or simple fixed platforms can be used in most cases. The traditional mobile platforms used in offshore geological surveys are pile-leg platforms, but when the shallow soil layer on the seabed is soft, the migration of the pile-leg platforms is inconvenient, and the mobile platforms suitable for deep wa...
