INTRODUCTION The high arch dams are usually located in the narrow valley with steep terrain. The construction space of the storehouse is limited, the construction process is complicated, the construction methods are complex and the operations cross each other. Which makes difficult to layout construction equipment, reduce work efficiency, and even generate security risks. Therefore, how to scientifically formulate construction plans, avoid collisions and rework, and achieve efficient and safe construction of storehouse are the focuses by all parties. According to the research [1-3], the rationality plan is directly relate to the successful implementation of the construction process. In the research about construction of time-space collisions, Hu Zhenzhong [4-6] integrated BIM and 4D technology to build structural collisions and security collision detection system. Wu Hao [7] integrated GNSS/GIS to guide cable cranes safety monitoring platform to achieve the cable crane safety operation analysis. Li Xuefeng[8] etl built cable machine and tower crane operation anti-collision system for Long Kai Kou hydropower. Xiao Zhihuai [9] combine GPS, rotating decoder and high-speed data acquisition card technology to design a dam building equipment anti-collision system. Wu Binping [10] cable machine analysis the selection of randomness and uncertainty of cable cranes, based on the edge of the limited criteria and space collisions to simulation cable cranes for arch dam. Wang Renchao [11] using spatial analysis and collision identification technology proposed a variety of 796
