description The invention discloses a water-rich tunnel construction method based on desert sand concrete, and relates to the technical field of water-rich tunnel construction. The water-rich tunnel construction method based on the desert sand concrete comprises the following steps that tunnel primary supporting is conducted, and arrangement of a tunnel primary supporting structure is completed; constructing a tunnel secondary lining arranged on the inner side of the tunnel primary support structure by using desert sand concrete; and when the inverted arch of the tunnel secondary lining is constructed, desert sand concrete is used for pouring. The desert sand is used as the concrete of the fine aggregate, and the desert sand concrete has the advantages of being low in rebound rate, easy to compact, high in early strength, small in later strength loss and small in fine particle and concrete separation, so that the structural strength and stability of the water-rich tunnel easy to support at the initial stage are improved
