Once-sinking horse-riding type open caisson anti-super-sinking and anti-deformation construction method
The invention discloses a one-time sinking horse-riding type open caisson anti-super-sinking and anti-deformation construction method, and belongs to key technology research of open caisson and pipe jacking construction along river quicksand stratum.The method comprises the following steps that S1, grouting guide pipes are laid, specifically, the grouting guide pipes are laid at the four corners of an open caisson, and the pipes are firmly positioned at designed positions through positioning steel bars; the metal pipeline joints are connected by adopting sleeves, and the connecting sleeves are suitable for adopting similar pipelines with a larger diameter model and are tightly sealed and wrapped with the metal pipelines; after the pipeline is installed in place, through hole inspection should be conducted immediately, and dredging should be conducted in time when blockage is found. In the sinking process of the riding type open caisson, the purposes of controlling the sinking elevation of the open caisson and controlling the deformation of the riding groove are achieved by applying the pre-buried grouting guide pipe and the supporting piece, the construction quality of the open caisson and the stability and safety of the later period are ensured, and finally the purposes of ensuring the construction safety of a building, shortening the construction period, reducing the engineering cost and improving the construction efficiency are achieved. And the later maintenance cost is eliminated, and good social reputation is obtained.
本发明公开了一种一次下沉骑马式沉井防超沉防变形施工方法，属于沿河流沙地层沉井及顶管建造关键技术研究，包括以下步骤：S1注浆导管敷设：在沉井四角敷设注浆导管，管道采用定位钢筋牢固地定位于设计位置；金属管道接头应采用套管连接，连接套管宜采用大一个直径型号的同类管道，且应与金属管道封裹严密；管道安装就位后应立即通孔检查，发现堵塞应及时疏通。在骑马式沉井下沉过程中，通过对预埋注浆导管和支撑件的应用，达到控制沉井下沉标高和控制骑马槽变形的目的，确保沉井施工质量、后期的稳定性、安全性，最终达到保证构筑物施工安全，加快施工工期、降低了工程成本，消除了后期的维修费用，取得了良好地社会信誉。
