Embodiment Construction

[0059] Below in conjunction with the drawings and preferred embodiments, the steel hanging box system and construction technology for the construction of underwater high pile caps proposed according to the present invention are described in detail as follows.

[0060] see figure 1 , figure 2 As shown, the steel hanging box system for the construction of underwater high pile caps when the preferred embodiment of the present invention is above the normal water level consists of corbels 2, stressed beams 3, steel hanging boxes 4, and suspension systems 5 composed of:

[0061] The corbel 2 has four corbels 2 in total. The four corbels 2 are respectively arranged on the outer edges of the four bored pile steel casings 1 along the bridge direction that are positioned above the normal water level 12.

[0062] The stressed beam 3 is composed of two stressed beams 31 and a plurality of secondary stressed distribution beams 32 . Wherein, one stressed beam 31 is arranged on two corb...

Abstract

The invention relates to a steel hanging box system for underwater high-rise pile cap construction and a construction technology thereof. The steel hanging box system is composed of a load-bearing beam component, a steel hanging box, a suspension system and brackets. The first brackets are welded on the positions above a normal water level of four bored pile steel pile casings, and the first brackets are used for supporting to splice the steel hanging box. The steel hanging box is hung through the suspension system which is supported on the inner pile tops of the bored pile steel pile castings, the supporting first brackets are cut off, the steel hanging box is sunk to a designed elevation, a bottom seal concrete layer is poured in the steel hanging box, water in the steel hanging box is pumped completely, in the state of being free of water, the second brackets are welded to the four bored pile steel pile castings again, the load-bearing beam component, a bottom plate of the steel hanging box and the bottom seal concrete layer are fixedly combined with the second brackets through bolts and bear loads, and at last the concrete layer, a bearing platform and a bridge pier are leveled through construction. According to the steel hanging box system for the underwater high-rise pile cap construction and the construction technology thereof, loads of splicing, lifting and bearing of the steel hanging box are all transmitted to engineering bored piles, the number of auxiliary equipment is reduced, operating is convenient and simple, and cost is saved.

Description

technical field [0001] The invention relates to bridge foundation construction machinery and technology in the field of highway bridges, in particular to a steel suspension box system and construction technology for underwater high pile cap construction. Background technique [0002] With the vigorous development of my country's national economy, it has promoted the advanced development of road transportation infrastructure, especially in recent years, there are more and more underwater bridge construction projects across rivers and seas, and the foundations of bridges in water are changing with each passing day. Bored pile foundations, caisson foundations , caisson foundation, underground continuous beam foundation and various combination foundations are widely used. The method of surrounding water for foundation construction has been continuously innovated. Double-wall steel cofferdams, single-arm steel cofferdams, locking steel pipe pile cofferdams, steel sheet pile coffer...
