Description

Auxiliary stool structure platform and the job practices thereof of anchorage system in the water
Technical field
What the present invention relates to is auxiliary stool structure platform and the job practices thereof of anchorage system in a kind of bridge water, it is applicable under deep water, big flow velocity, strong tide, riverbed intectate or few covering layer condition carries out in the bridge foundation construction, in the time of need setting up the over-water construction platform, adopt the auxiliary stool structural entity platform of anchorage system in the water.Belong to technical field of bridge construction.
Background technology
In the construction of bridge deep water foundation, The water is deep and the current fast owing to base position, it is frequent to be subjected to strong tide to influence SEA LEVEL VARIATION, and intectate or few covering layer on the riverbed, operation platform is difficult to build or keeps stable, the general plug in guide pile of beating that adopts forms constructure scheme such as platform, whole steel cofferdam platform or floating platform, but these schemes exist guide pile can't squeeze into the riverbed respectively or to insert the riverbed few and be difficult to stablize, whole steel cofferdam engineering quantity is big, hanging device requires high, problems such as floating platform poor stability have been brought certain difficulty to construction.
Summary of the invention
The objective of the invention is to change frequent at The water is deep and the current fast, influenced by strong tide and above-mentioned unfavorable conditions bridge foundation construction difficulties down such as riverbed intectate or few covering layer, propose anchorage system is assisted in the water stool structural entity platform structure and job practices thereof.This platform structure forms the stool structure with space steel truss girder and supporting steel pipe stake, and the steel anchor rod by the steel pipe pile bottom forms the effectively fixed of steel pipe pile and basement rock, and with the auxiliary rock-steady structure of anchorage system after as platform building and formation.
Technical solution of the present invention: the auxiliary stool structure platform of anchorage system in the water, its structure is to comprise anchorage system in integral platform trusses, steel pipe supporting pile and the water, wherein steel pipe support column upper end is affixed with the integral platform trusses, at the bottom of the positioning steel tube supporting pile mouth form by anchor pole in the anchorage system in the water and riverbed basement rock fixed, and with anchorage facility waterborne as the supplementary structure of stablizing the stool structure platform.
The job practices of the stool structure platform that anchorage system is assisted in the water, the construction sequence of this method is divided into, one, assembly unit integral platform trusses on the spliced ship, and lay anchorage system in the water in the pier position, and the strand anchor arrangement, anchorage system comprises the concrete weight anchor in the described water, anchor chain, anchor line, anchor pole, described strand anchor arrangement comprises hoist engine, tackle pulley etc.; Two, integral platform trusses transportation by driving is to the pier position, anchor line in the anchorage system in the water is carried out the transition on the platform trusses, by the folding and unfolding anchor line and to every Bower Anchor rope pretension is set, come the platform trusses is accurately located, grasp the displacement rule of platform, utilize in the water concrete weight anchor in the anchorage system platform trusses position to be adjusted and accurate location with tide bulge and fall; Three, the left and right sides of stool structure platform symmetry installing and locating steel pipe supporting pile selects flow velocity symmetry hour in the platform fixed frame to insert some positioning steel tube supporting piles, and this moment, the platform trusses still can slide along the supporting pile easy on and off; Four, utilize tide water level to change the platform trusses is consolidated in positioning steel tube supporting pile top, realize the system conversion of stool structure platform, the system conversion of described stool structure platform is meant that the weight of integral platform trusses is by being converted to positioning steel tube supporting pile top on the spliced ship, when high-tide level platform trusses rises to positioning steel tube supporting pile top, rapidly that positioning steel tube supporting pile top is fixing with the welding of platform trusses, the platform trusses is converted on the steel pipe supporting pile when water level falls, the assembly unit iron barge is with drawdown, and withdraw from spliced ship, finish the system conversion; Five, utilize anchor pole with positioning steel tube supporting pile and riverbed basement rock anchoring, and the concrete weight anchor increase stool structure platform in the anchorage system is stable in the existing water of utilization, utilize jumbolter to overlap the brill anchor hole under water during concrete the construction, insert anchor pole and slip casing by pressure anchoring, pour into the high early-strength of 3m concrete under water during slack tide in the positioning steel tube supporting pile steel pipe, realize steel pipe supporting pile and basement rock anchoring.
Advantage of the present invention: this platform structure is simple, weight is light, the face that blocks water is little, with low cost, utilize tidal range implementation platform Fast Installation, utilize anchorage waterborne location and increase platform stable, the processing method of succinct practicality has been proposed for the foundation construction platform building of deep water, big flow velocity, strong tide, riverbed intectate or few covering layer condition in the bridge construction, through suitably improving, also can be applicable to building of other pier, have bigger promotional value.Effectively having overcome in the prior art existing positioning steel tube supporting pile, to insert the riverbed few and be difficult to stablize, whole steel cofferdam engineering quantity is big, hanging device require high, floating platform poor stability, defective such as difficulty of construction is big.
