Multifunctional trestle construction method suitable for thick pebble bed
The invention relates to the field of bridge construction, and particularly discloses a multifunctional trestle construction method suitable for a thick pebble bed, which comprises the following steps: after a steel pipe pile is vibrated to sink to the designed depth of a pipe pile, drilling a riverbed pebble bed in the steel pipe pile, lowering a reinforcement cage and pouring underwater concreteto form an anchor pile after drilling to the designed depth of an anchor hole; anchoring the lower part of the concrete anchor pile with riverbed bedrock, and anchoring the upper part of the concreteanchor pile with the steel pipe pile, so that the steel pipe pile is anchored with riverbed bedrock strata. According to the construction method, for trestle construction on bed rock covered with a thick pebble bed, anchor pile reinforcement is conducted on steel pipe piles, so that the problems that a trestle is difficult to construct on a pebble bed riverbed, the enough buried depth cannot be guaranteed due to the fact that steel pipe piles are difficult to insert and drive are solved, and the vertical bearing capacity and the transverse stability of a whole trestle are improved. The trestle has multiple functions of transportation, piling, drilling (anchoring piles) and the like, and can meet the requirements of various construction stages.
本发明涉及桥梁建设领域，具体公开了一种适用于厚卵石层的多功能栈桥施工方法，其通过在钢管桩振沉至管桩设计深度后，再在钢管桩内对河床卵石层进行钻孔，钻至锚孔设计深度后，下放钢筋笼并灌注水下混凝土形成锚桩，混凝土锚桩下部与河床基岩锚固，混凝土锚桩上部与钢管桩锚固，从而将钢管桩与河床基岩层锚固连接。该施工方法针对在覆厚卵石层的基岩上进行栈桥施工，通过对钢管桩进行锚桩加固，解决了卵石层河床栈桥施工困难和钢管桩插打困难不能保证足够入土深度等问题，增加了栈桥整体的竖向承载能力和横向稳定性。栈桥具有运输、打桩、钻孔(锚固桩)等多种功能，可满足各个施工阶段的需求。
