The invention provides a high pressure manifold device for carbon dioxide dry fracturing. Real-time pressure of a high pressure pipeline in a fracturing construction is monitored by arranging a pressure sensor on a tee joint. A 3-inch cock is used on each pipeline to carry out isolation and a 2-inch cock is used on each pipeline to carry out pressure relief, and therefore the problems of piercing-caused leakage of the pipelines and risks caused by dry ice formation and gasification of carbon dioxide in a part of pipelines are solved. A check valve is arranged on each pipeline to prevent liquid from backflow; two primary pipelines are connected to ensure that the liquid in the two primary pipelines is averagely distributed. The high pressure manifold device has the characteristics of safety, standardization, reasonability, convenience, reliability and the like. The pipeline connection time can be greatly shortened, the damage degree of valve components for high pressure pipelines is reduced, the labor intensity of personnel is reduced and the construction efficiency is improved. Aiming at the characteristics of carbon dioxide, the safety control devices, such as a plurality of cock valves, the check valves and the pressure sensors, are arranged on the high pressure pipelines, so that the risks in the carbon dioxide dry fracturing construction can be greatly reduced, and the HSE (Health and Safety Executive) operation requirements in a fracturing field and the normal field construction requirements are met.
