The invention relates to high-strength concrete, a pipeline prepared by the high-strength concrete and a method for preparing the pipeline, and belongs to the field of concrete. The technical problem solved by the invention is to provide the concrete with high compressive strength. The high-strength concrete is prepared from the following raw materials in part by weight: 0.8 to 1.2 parts of cement, 1.0 to 1.2 parts of mixed sand, 2.9 to 3.4 parts of gravel with a crushing value of between 9.0 and 10.0 percent, 0.25 to 0.4 part of water, and a water reducing agent which accounts for 0.7 to 0.9percent of the total weight of the raw materials of the concrete, wherein the mixed sand is formed by mixing 40 to 60 percent of river sand and 60 to 40 percent of artificial sand. The high-strength concrete does not need to add the raw materials such as mineral powder, ground sand and the like additionally, which not only simplifies working procedures, but also reduces production cost; and the high-strength concrete has high compressive strength and good anti-permeability performance, can be used for the preparation of deep-buried concrete pipelines, provide a new selection for the field, and has broad application prospect.
