Prefabricated assembly type UHPC pipe network floating structure and construction method thereof

Abstract

The invention relates to a prefabricated assembly type UHPC pipe network floating structure and a construction method. The prefabricated assembly type UHPC pipe network floating structure is a UHPC pipe network framework obtained by assembling UHPC pipes and comprises the UHPC pipes and accessories used for connecting the UHPC pipes, and the UHPC pipes are connected and assembled through the accessories to form a UHPC pipe network framework structure. A UHPC pipe diameter, a pipe wall thickness, a pipe solid part density and a water density meet the following relation: R*rho w> 2*d*rho uhp, wherein R is the radius of the UHPC pipe, the d is the wall thickness of the pipe, the rho w is the density of water, and the rho uhp is the density of UHPC. The prefabricated assembly type UHPC pipe network floating structure is in a floating state. Organic unification of a buoyancy body and a structural body is achieved, self-weight of the structure is greatly reduced, and an effective load of thefloating structure is increased.

Description

technical field [0001] The invention belongs to the technical field of marine engineering facilities. More specifically, the present invention relates to a prefabricated UHPC pipe network floating structure and a construction method. Background technique [0002] With the implementation of my country's maritime power strategy, the demand for marine infrastructure is on the rise. In marine infrastructure, marine floating platforms are a very important category. Floating platforms play an important role in offshore construction, resource exploration, marine farming, yacht docks and military facilities. For a long time, the vast majority of various types of offshore platforms are made of steel materials, while offshore platforms built with other materials are very rare. Offshore platforms constructed of metal materials such as steel have their advantages, but the existing problems are also very prominent, that is, the structure is easily corroded, and frequent anti-corrosion ...

AI Technical Summary

Problems solved by technology

[0004] However, the large-scale UHPC box structure currently used has a structural composition including bottom plate, roof plate, partition plate, beam, column, stiffener, etc., and the local structure size changes greatly.

Considering various factors, relatively conservative and heavy dimensions are often used when designing UHPC structures, so that the potential advantages of UHPC materials cannot be fully utilized
