Deep sludge geology open caisson construction method
The invention discloses a deep sludge geology open caisson construction method. The efficient and accurate construction process is achieved through five core steps. Firstly, a pre-assembled immersed tube is transferred to a construction position and gradually sinks into a sludge layer, and meanwhile a well mouth and a well interior platform are installed. And then, the sinking speed and stability of the immersed tube are controlled by excavating sludge through the in-well platform, and the well mouth platform is responsible for uniformly distributing the excavated sludge on the periphery of the immersed tube. In order to guarantee the perpendicularity of the immersed tube, deviation adjustment is carried out through differentiated operation of a wellhead and a platform in the well. Along with sinking of the sinking pipe, the wellhead platform regulates and controls the in-well platform to ascend and descend so as to adapt to different depths, and construction continuity is kept. And finally, after the immersed tube reaches the preset depth, the platform moves upwards, a new immersed tube is in butt joint, and the steps are repeated till completion. According to the method, the construction precision and efficiency are greatly improved, the environmental influence is remarkably reduced, and the method has remarkable practical value and popularization significance for large infrastructure construction under the deep sludge geology.
本发明公开了一种深层淤泥地质沉井施工方法，通过五个核心步骤实现高效、精确的施工过程。首先，预装配的沉管被转移到施工位置并逐步沉入淤泥层，同时安装井口和井内平台。接下来，通过井内平台采挖淤泥控制沉管的下沉速度和稳定性，井口平台则负责将挖出的淤泥均匀分布于沉管外围。为保证沉管垂直度，通过井口和井内平台的差异化操作进行调偏。随着沉管的下沉，井口平台调控井内平台升降以适应不同深度，保持施工连续性。最后，当沉管达到预定深度后，平台上移，对接新沉管并重复以上步骤直至完成。该方法不仅大幅提升了施工精度与效率，还显著降低了环境影响，对于深层淤泥地质下的大型基础设施建设具有显著的实践价值和推广意义。
