Embodiment 1
[0034] Embodiment 1: A certain oil exploration project—the drilling platform of the oil field on Coral Island. The working platform is located in the intertidal waters, submerged at high tide and exposed at low tide. It is directly attacked by wind, waves and current velocity in the open sea. The drilling construction is greatly disturbed and normal work cannot be carried out. The foundation on the coral island is mainly composed of coral debris and other marine biological debris. Long-term seawater cleared coral sand has the characteristics of large particle density, high water content, high porosity, low dry density, and high compressibility. High and high porosity. According to the actual situation of the foundation and the construction site, after topographical survey, research design, feasibility analysis, check calculation and demonstration, the fast embankment method on the coral island is adopted.
[0035] First, on the island The contour line of the embankment is d...
Embodiment 2
[0039] Example 2: A coral island project requires fast embankment. The embankment line of the project and the foundation of the wharf have passed routine surveys, divided soil layers and static load tests. The cemented coral reef clastic deposits the surface layer, which is a heterogeneous foundation. Moreover, it has the characteristics of high water content, large void ratio, low bearing capacity and shear strength, and high sensitivity. In the case of high bearing capacity, it is easy to be accompanied by inhomogeneity, which is a typical heterogeneous weak foundation.
[0040] The method adopted is basically the same as that of Embodiment 1, except that: (1) the prefabricated installation wharf adopts old containers as the hard shell structure of the wharf, and the single size of the container is: 12200mm×2440mm×2440mm. During processing, the inside of the container is reinforced by angle steel welding to prevent deformation of the container due to side pressure. The bott...
