Shield construction preparation device for underneath passing existing tunnel and construction method of shield construction preparation device
The shield construction preparation device comprises a workbench detachably arranged on a foundation, an avoiding hole is formed in the middle of the workbench, a steel pile is arranged in the avoiding hole in a penetrating mode, and the structural strength of the foundation is improved by inserting the steel pile into the foundation; four position control assemblies are oppositely arranged on the upper side of the workbench, a drill bit assembly is arranged on the lower portion of the steel pile, a liquid containing cavity is formed in the drill bit assembly, a liquid injection assembly is arranged on the outer side of the steel pile, the lower portion of the liquid injection assembly extends into the liquid containing cavity, and the position control assemblies are used for making the liquid injection assembly abut against the outer side wall of the steel pile. The design is ingenious, the overall construction efficiency is greatly improved, it is guaranteed that the construction economy is high, the construction effect is good, and good economic benefits are achieved.
本发明提供一种下穿既有隧道的盾构施工准备装置及其施工方法，包括可拆卸设置在地基上的工作台，工作台的中部设有避让孔，避让孔内穿设有钢桩，通过钢桩插打入地基中提高地基的结构强度，工作台的上侧分别相对设置有四个控位组件，钢桩的下部设有钻头组件，钻头组件内设有容液腔，钢桩的外侧设有注液组件，注液组件的下部伸入容液腔内，控位组件用于将注液组件抵靠在钢桩的外侧壁。本发明设计巧妙，大幅度提高整体的施工效率，保证了施工经济性高效果好，具有良好的经济效益。
