Construction method for enabling pipe pile of shortcut steel trestle to enter rock
The invention relates to the field of road and bridge engineering, in particular to a road steel trestle pipe pile rock-entering construction method which is simple in operation procedure, efficient and reliable and comprises the following steps that a, first-time initial inserting and driving are carried out, and a steel pipe pile enters a river bed rock layer to be fixed; b, secondly, a percussion drill is used for impacting a riverbed rock layer from the interior of the steel pipe pile to form a hole channel till the designed rock entering depth is reached, and slag is removed; c, secondary inserting and driving of the steel pipe pile are conducted, and it is ensured that the bottom of the steel pipe pile reaches the bottom elevation position of the guide hole channel; d, the steel pipe pile is filled with graded broken stone through a funnel, the filled graded broken stone is impacted, extruded and compacted through an impact hammer, pile bodies and hole positions are compactly filled, and the stability of a steel pipe pile foundation is ensured; and e, structural construction of a steel pipe pile connecting rod system, a steel pipe pile top bearing beam, a supporting cross beam, a bailey beam supporting frame, a formed bridge deck slab and a handrail is conducted on the steel pipe piles. And the device is particularly suitable for the construction of the steel trestle pipe pile entering rock.
本发明涉及道路桥梁工程领域，尤其是操作工序简单、高效、可靠的便道钢栈桥管桩入岩施工方法，包括如下步骤：a、首先，实施第一次初插打，让钢管桩进入江河床岩石层中固定；b、其次，利用冲击钻机从钢管桩内部对江河床岩石层进行冲击成孔道，直至设计的入岩深度、并清渣；c、进行钢管桩的二次插打，确保钢管桩底部达到引孔道的底部标高位置；d、利用漏斗从钢管桩内部采用级配碎石进行填充，用冲击锤对所填级配碎石进行冲击挤压密实，使桩身和孔位填充密实，确保钢管桩基础的稳定性；e、在所述的钢管桩上进行钢管桩连接杆系、钢管桩顶承重梁、支撑横梁、贝雷梁支撑架、成型桥面板、栏杆的结构施工。尤其适用于便道钢栈桥管桩入岩施工之中。
