Steel pipe pile construction method for deepwater slope bare rock
The invention provides a steel pipe pile construction method for deepwater slope bare rock, and relates to the field of steel pipe pile trestle construction. Comprising the following steps that a buoyancy tank is positioned, specifically, the buoyancy tank is hoisted near a pile position and anchored to a nearby steel pipe pile or/and a temporary anchoring point arranged on the shoreside; slope leveling is conducted, specifically, a percussion drill is hoisted on the buoyancy tank, a first percussion hammer is installed at the percussion end of the percussion drill, and the first percussion hammer impacts the bare rock slope riverbed till a horizontal construction face is formed on the riverbed; the percussion drill is replaced with a second percussion hammer, the second percussion hammer impacts the horizontal construction face to form a pit with the depth of 50 cm, and the temporary steel casing is installed in the pit; hole guiding is conducted, specifically, the percussion drill is replaced with a third percussion hammer, and the third percussion hammer of the percussion drill impacts the pit in the temporary steel casing for hole guiding; a guide pipe is installed in the temporary steel casing to pour underwater concrete, and a steel pipe pile is inserted into the temporary steel casing. The problem that the buoyancy tank is difficult to fix is solved, and deepwater bare rock pile planting is achieved.
本发明提出了一种深水斜面裸岩的钢管桩施工方法，涉及钢管桩栈桥施工领域。包括以下步骤：浮箱定位：浮箱吊装在桩位位置附近，并锚固在附近的钢管桩或/和岸边设置的临时锚固点；斜坡找平:冲击钻机吊装在浮箱上，冲击钻机的冲击端安装冲击锤一，冲击锤一撞击裸岩斜坡河床，直至河床形成一个水平施工面；临时钢护筒定位：冲击钻机换用冲击锤二，冲击锤二撞击水平施工面，形成一个深度为50厘米的坑位，坑位中安装临时钢护筒；引孔：冲击钻机换用冲击锤三，使冲击钻的冲击锤三撞击临时钢护筒内的坑位进行引孔；植桩：在临时钢护筒内安装导管浇筑水下砼，临时钢护筒内插入钢管桩。本申请不仅解决了浮箱难以固定的情况，还实现了深水裸岩植桩。
