Abstract

The invention discloses a self-preloading dock entrance supporting system and a construction method thereof, and belongs to the technical field of engineering supporting. According to the technical scheme, a steel pipe main support, a steel enclosing purlin and a latticed column form an assembly type frame structure, one end of the steel pipe main support is a fixed end, the other end of the steel pipe main support is a movable end, the movable end uses an intelligent pressurization node, and a sliding type support and an automatic prestress applying system are integrated. The sliding support achieves axial telescopic adjustment through a sliding guide rod and a limiting device, and the automatic prestress applying system comprises an intelligent control unit, a hydraulic module and a stress sensing system. The construction method comprises the steps of concrete support pouring, steel enclosing purlin and latticed column mounting, prefabricated support unit hoisting, prestress applying and monitoring, multi-layer support arrangement and the like. The temporary supporting device has the beneficial effects of being reasonable in structure, convenient to install, safe, efficient and suitable for temporary supporting in complex environments such as dry docks and foundation pits, and the construction efficiency and the structural safety are improved.
