Underwater anchorage system auxiliary wooden stool structure platform and construction method thereof

Abstract

The invention relates to a stool platform assisting anchorage system in water and the construction method. The structure is that the upper end of support pile of steel pipe is fixed with the whole platform truss; anchor rope of anchorage system in water is fixed with the whole platform truss; the lower end of support pile of steel pipe is fixed with riverbed rock. The construction method is that the whole platform truss is assembled on assembling ship and anchorage system in water is set at the position of pier; the whole platform truss is transported to the pier position in floating and by using anchorage system in water the platform truss is located accurately; support piles of steel pipe are installed symmetrically; by using variety of water level the platform truss is fixed on the top of support pile to accomplish system transformation; by using anchor rod the support pile of steel pipe is fixed with the bedrock and by using prior anchorage system platform stability is increased. The invention is provided with simple structure, light weight, small water resistance surface and low cost. Simple and practical method is proposed for building basic construction platform under conditions of deep water, large flowing speed, strong tide, no covering layer for riverbed or less covering layer for riverbed.

Description

technical field [0001] The invention relates to a bench structure platform assisted by an anchorage system in the water of a bridge and a construction method thereof, which is suitable for bridge foundation construction under the conditions of deep water, high flow velocity, strong tide, and no or little covering layer on the river bed. When it is necessary to establish a construction platform above water, an integral platform with a bench structure assisted by an anchorage system in water is used. It belongs to the technical field of bridge construction. Background technique [0002] In the deep-water foundation construction of bridges, due to the depth of the foundation position, the water level changes frequently due to strong tides, and there is no or less covering layer on the river bed, it is difficult to build or maintain a stable construction platform. Generally, positioning piles are used to form the platform. , integral steel cofferdam platform or floating platfor...

Problems solved by technology

[0002] In the deep-water foundation construction of bridges, due to the depth of the foundation position, the water level changes frequently due to strong tides, and there is no or less covering layer on the river bed, it is difficult to build or maintain a stable construction platform. Generally, positioning piles are used to form the platform. , integral steel cofferdam platform or floating platform and other construction schemes, but in these schemes, positioning piles cannot be driven into the river bed or are inserted into the river bed too few to be stable, the overall steel cofferdam has a large amount of engineering, high requirements for hoisting equipment, and the floating platform is stable Poor performance and other problems have brought certain difficulties to the construction
