Movable prefabricated multi-barrel type gravity mixed foundation

Abstract

The invention discloses a movable prefabricated multi-barrel type gravity mixed foundation, comprising a plurality of barrel-type foundations which are axially arranged in parallel and share common surface on a barrel cover, wherein an upper barrel-type structure with an upward opening is coaxially and fixedly connected with the barrel-type foundation by the barrel cover thereon; a connecting bottom plate and rib plates which are connected into a whole with the barrel covers of the plurality of barrel-type foundations are used for connecting the upper barrel-type structures; the bottom surface of the connecting bottom plate has common surface with the bottom surface of the barrel cover of the barrel-type foundation; a foundation bearing platform positioned at the mixed foundation center is arranged on the connecting bottom plate; the barrel body of each upper barrel-type structure is filled with heavy objects; and the barrel cover of the barrel-type foundation is provided with reserved through hole capable of being opened and closed. The movable prefabricated barrel-type gravity mixed foundation does not need large transport ships when in transportation, and site installation doesnot need large hoisting ships; and the positioning and sinking equipment is simple, the construction is simple and convenient, the sinking speed is fast, the skewness is easily controlled, the vacuumpre-pressing and heavy objects filling have significant pre-pressing effect to foundation consolidation 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 multi-tube 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 k...

Problems solved by technology

[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.
