Abstract
The invention discloses a turbulent flow energy-dissipating anti-scouring open caisson and a construction method thereof, and relates to the technical field of bridge deepwater open caisson foundations. The turbulent flow energy-dissipating anti-scouring open caisson comprises an open caisson body, a bottom-expanded stepwell, concrete cover plates and turbulent flow dimension stones, wherein the open caisson body comprises an open caisson bottom section and an open caisson upper section which are connected to each other, and a top cover plate is arranged on the open caisson upper section. Thebottom-expanded stepwell is arranged along the periphery of the open caisson bottom section and comprises a bottom-expanded stepwell outer wall plate and a bottom-expanded stepwell inner wall plate connected to the outer wall of the open caisson bottom section, the bottom-expanded stepwell inner wall plate divides the space between the bottom-expanded stepwell outer wall plate and the outer wall of the open caisson bottom section into a plurality of bottom-expanded stepwell units, the concrete cover plate is arranged in every bottom-expanded stepwell unit, flow guide brackets are arranged at the top of the bottom-expanded stepwell outer wall plate and positioned above the concrete cover plates, and the turbulent flow dimension stones are laid on the concrete cover plates. The turbulent flow energy-dissipating anti-scouring open caisson can dissipate energy of scouring waterflow to prevent an open caisson foundation from being destroyed by scouring, thereby being low in construction difficulty and highly economic.
Description
technical field [0001] The invention relates to the technical field of bridge deep-water caisson foundations, in particular to a flow-disturbing, energy-consuming, scour-proof caisson and a construction method. Background technique [0002] As the span of the bridge continues to increase, the scale of the deep water caisson foundation of the bridge is also increasing. With the increase of the plane size of the caisson foundation, the local scour of the foundation is intensified. In order to avoid the caisson foundation from being damaged by erosion, The existing technology generally adopts the following two methods: [0003] 1. Bury the base of the caisson foundation deeper; [0004] 2. Set up protective bodies on the riverbed around the caisson foundation to reduce erosion. [0005] However, the existing technology has the following problems: the base of the caisson foundation is buried deeper, which increases the difficulty and risk of caisson sinking construction; the s...
