An active drainage and pressure relief bridge construction water platform

Abstract

The invention discloses an active drainage pressure relief bridge construction overwater platform which structurally comprises flow-resisting platforms, connection platforms, a locking device, liftingrib columns, frames, bases and rotators. The flow-resisting platforms are horizontally mounted on left and right sides of the connection platforms, the bottoms of the connection platforms are nestedwith the locking device, shells are reinforced through bolts, each lifting rib column is vertically fixed at the bottom of the corresponding rotator and movably connected with the corresponding frame,each frame is vertically welded at the top of the corresponding base and forms an integral structure, and each rotator is nested with a rib head at the top of the corresponding lifting rib column. Tosum up, after improvement, ability of the flow-resisting platforms in cleaning floating objects is improved, so that damage caused to the platforms by the floating objects in severe environment is avoided; when in use, a drainage push plate has anticollision effect and certain floatability, thereby being of certain assistance in improving stability of the platforms.

Description

technical field [0001] The invention relates to a bridge construction water platform, in particular to an active water drainage and pressure relief bridge construction water platform. Background technique [0002] Bridges are widely used between municipal roads and river crossings. Due to topographical reasons, the technical difficulty of bridges crossing the water surface is more difficult. It is necessary to lay platforms on the river for auxiliary construction, so as to facilitate operations such as pouring cement in deep water areas, but Because the water flowing in the river will have a certain impact on the water surface construction platform: [0003] The water flow is affected by the turbulent vortex from the bottom, and the distribution of the flow velocity along the water depth is uneven. The flow velocity near the water surface is relatively high. In bad weather, the water flow will continuously impact the water platform, and some floating objects on the flow will...

[0002] Bridges are widely used in municipal roads and river crossings. Due to topographical reasons, it is more difficult to construct bridges across water surfaces. It is necessary to lay a platform on the river for auxiliary construction, so as to facilitate operations such as pouring cement in deep water areas. However, Because the water flowing in the river will have a certain impact on the water surface construction platform:

[0003] The water flow is affected by the turbulent vortex from the bottom, and the distribution of the flow velocity along the water depth is uneven. The flow velocity near the water surface is relatively high. In bad weather, the water flow will continuously impact the water platform, and some floating objects that flow will impact the surface of the platform, constantly Accumulation will cause the platform to be lifted, and subsequent cleaning of floating objects is more difficult
