Typhoon high-incidence area large-clearance heavy-load liftable navigation hole trestle
The invention discloses a typhoon high-incidence area large-clearance heavy-load liftable navigation hole trestle which comprises a supporting system, a bridge span system, a lifting system, an anti-collision system, a common trestle body and a counter-pulling device. Bailey beams with the length of 51 m are adopted in the bridge span structure, and 18 pieces of Bailey beams are arranged side by side, the bailey beams are constructed to be of a three-span continuous structure by arranging refined steel rolling counter-pulling points on the side spans, the maximum sagging moment in the mid-span is reduced, the bearing capacity of the bridge span structure is improved, and therefore the requirements for large span and heavy loads of the bridge span structure are met, the lifting system is provided with a guiding device, and the guiding and shaking preventing effects are achieved; the supporting steel pipe piles and the auxiliary steel pipe piles are arranged in a triangular shape, the wind resistance of the lifting frame is improved, and therefore the requirements for high lifting height and high wind resistance are met, and the problems that a liftable navigation hole trestle in a typhoon high-incidence area is large in span, high in lifting height, large in traffic load, high in anti-collision and wind-resistant requirements and the like are solved.
本发明公开了一种台风高发区大净空重载荷可升降通航孔栈桥，包括支撑系统、桥跨系统、升降系统、防撞系统、普通栈桥、反拉装置，桥跨结构采用贝雷梁51m长，贝雷梁采用18片贝雷并排布置，并通过在边跨设置精轧钢反拉点将贝雷梁构造为三跨连续结构，降低中跨跨中的最大正弯矩，提高桥跨结构承载能力，从而，满足桥跨结构大跨度、重载荷的要求，升降系统设置导向装置，起到导向和防止晃动的作用，支撑钢管桩和辅助钢管桩按三角形布置，提高升降架的抗风能力，从而满足提升高度高，抗风要求高的要求，解决台风高发区可升降通航孔栈桥跨度大、提升高度高，通行荷载大及防撞、抗风要求高等难题。
