Construction method of lifting device of navigation temporary steel bridge under complex hydrogeological conditions
The invention relates to a construction method of a lifting device of a navigable temporary steel bridge under complex hydrogeological conditions. The construction method comprises steps that detection and lofting are conducted in advance, and the installation position is determined; steel pipe piles are constructed, steel pipe sections are machined and transported to a construction site, the steel pipe sections are lengthened to form the steel pipe piles, the steel pipe piles are driven and sunk on the two sides of the temporary steel bridge, and after sinking is completed, flat braces, brackets and in-pile stiffening plates are installed; height adjusting devices are installed, specifically, the height adjusting devices are installed on the steel pipe piles, then all the height adjusting devices are adjusted to enable the top faces of the height adjusting devices to be horizontal, and then reinforcing steel plates are welded to the height adjusting devices and the steel pipe piles; a bearing beam and a limiting device are installed, specifically, the bearing beam is hoisted to the position above the height adjusting device, the bearing beam is fixed to the height adjusting device, then the limiting device is installed between the two opposite steel pipe piles, and the limiting device is located below the bearing beam; a lifting device and a protection box are installed, a plurality of distribution beams are installed above the bearing beam, and after installation is completed, the lifting device and the protection box are installed on the distribution beams. The construction process is simple, and the period is short.
本申请涉及一种复杂水文地质条件下通航钢便桥的提升装置的施工方法，包括预先检测放样，确定安装位置；钢管桩施工，加工钢管段并运输至施工现场，将钢管段接长以构成钢管桩，将钢管桩打设沉放在钢便桥两侧，沉放完成后，安装平联、牛腿和桩内加劲板；调高装置安装，调高装置安装在钢管桩上，然后调节所有调高装置使其顶面水平，接着在调高装置与钢管桩上焊接加固钢板；承重梁及限位装置安装，吊装承重梁至调高装置上方，将承重梁固定在调高装置上，接着在相对的两个钢管桩之间安装限位装置，限位装置位于承重梁下方；提升装置和防护箱安装，在承重梁上方安装若干分配梁，完成后，将提升装置和防护箱安装在分配梁上。使得施工流程简单，周期短。
