Movable Prefabricated Cylinder Gravity Hybrid Foundation

Abstract

The invention discloses a movable prefabricated cylindrical gravity hybrid foundation, which comprises a cylindrical foundation, a foundation cap is fixedly connected to the center of the upper surface of the cylindrical foundation, and the upper surface of the cylindrical foundation is coaxial An upper cylindrical structure with an upward opening is fixedly connected, and the interior of the upper cylindrical structure is divided into multiple chambers by reinforcing ribs arranged between its cylinder wall and the foundation cap; the interior of the cylindrical foundation It is divided into multiple chambers through the reinforcing ribs provided under the cylinder cover. Each chamber of the cylinder foundation is provided with a switchable reserved through hole on the cylinder cover of the cylinder foundation. The upper cylinder Each chamber of the structure is filled with a weight. The invention does not require a large transport ship for transportation, and does not require a large hoisting ship for on-site installation; the positioning sinking equipment is simple, the construction is simple, the sinking speed is fast, the deflection is easy to control, and the vacuum preloading and heavy object filling preload the foundation reinforcement. The effect is outstanding, and the comprehensive engineering cost is low.

Description

technical field [0001] The invention relates to a foundation in port, ocean, water conservancy and bridge engineering, in particular to a movable prefabricated cylindrical gravity mixed foundation. Background technique [0002] At present, in port, marine, water conservancy and bridge projects, the foundations on soft soil foundations are mainly pile foundations, which require complex construction equipment, high costs, and high requirements for natural conditions. When the environmental loads such as wind, wave and current are complex, especially in river courses, estuaries and sea areas with high tidal currents, the requirements for displacement and positioning of piling equipment are very high, and the piling efficiency is relatively low. At the same time, on the muddy soft soil foundation, the design depth of the pile will increase, and the cost will also increase immediately. Contents of the invention [0003] In order to solve the technical problems existing in the ...

[0002] At present, in port, marine, water conservancy and bridge projects, the foundations on soft soil foundations are mainly pile foundations, which require complex construction equipment, high costs, and high requirements for natural conditions

When the environmental loads such as wind, wave and current are complex, especially in river courses, estuaries and sea areas with high tidal currents, the requirements for displacement and positioning of piling equipment are very high, and the piling efficiency is relatively low

At the same time, on the muddy soft soil foundation, the design depth of the pile will increase, and the cost will also increase accordingly.
