An offshore foundation support structure and its construction method

Abstract

The invention relates to a marine foundation supporting structure which comprises a tubular pile, a precast concrete platform and a piling guide frame, wherein the tubular pile is sleeved with the interior of the piling guide frame and is fixedly connected with the piling guide frame, the precast concrete platform is fixedly at the upper part of the tubular pile, and the precast concrete platform locates on the piling guide frame. The invention further relates to a construction method of the supporting structure, which comprises the following step: sleeving the tubular pile into the guide pipe of the piling guide frame and piling into bottom of the sea; injecting binder into a seam between the guiding pipe and the tubular pile and adjusting the horizontality of the piling guide frame before incomplete solidification; sleeving the precast concrete platform onto the tubular pile and locating the precast concrete platform onto the piling guide frame and enabling the precast concrete platform and the piling guide frame to be connected through a prestress high-strength rod or a high strength steel bar; pouring concrete into a gap between the precast concrete platform and the outer wall of the tubular pile as well as the gap between the precast concrete platform and the prestress high-strength rod or the high strength steel bar; and exerting prestressing force onto the prestress high-strength rod, and if the high strength steel bar is used, omitting the step. The marine foundation supporting structure provided by the invention has a stable structure and is convenient to construct.

Description

technical field [0001] The invention relates to the field of support structures, in particular to an offshore foundation support structure and a construction method thereof. Background technique [0002] In the 21st century, facing the pressure of the depletion of conventional energy sources and the deterioration of the environment, and at the same time facing the tasks of energy conservation, emission reduction, and economic development, it is imminent to find alternative green new energy sources. Tidal current power generation is a power generation method that uses tidal kinetic energy. The energy generated by the flow of seawater drives the turbine to rotate to drive the generator to generate electricity. As a kind of green energy, tidal current energy has become the object of research and development by countries all over the world because of its advantages such as good renewability, strong predictability, cleanness and environmental protection, and abundant reserves. ...
