Problems solved by technology

[0003] However, for a long time, the manufacturing technology of pipe piles in my country's industrial and civil construction projects has been unsatisfactory. For places with high requirements for crack resistance and bending moment of piles, for those places with high requirements for crack resistance and bending moment, only the outer diameter of pipe piles can be increased, which will increase the manufacturing cost of pipe piles and reduce the production efficiency of pipe piles

Abstract

The invention relates to a formula for improving cracking bending moment of a concrete pipe pile and a preparation method thereof. The formula comprises the following components by mass percent: 12-16% of cement, 2-6% of admixture, 38-42% of sand, 27-32% of stones, 2-4% of water reducer, 3-4% of methanol, 3-4% of aluminum salt waterproof agent, and 4-6% of water. The concrete pipe pile prepared according to the formula and the preparation method disclosed by the invention has the advantages of being reasonable in material collocation, convenient to manufacture, low in cost and the like; the cracking bending moment of the pipe pile can be improved; the molding quality of the pipe pile is ensured; the energy consumption and the production-manufacturing cost are reduced.

Description

technical field [0001] The invention relates to the technical field of pipe pile manufacturing, in particular to a formula for improving the crack resistance bending moment of concrete pipe piles and a preparation method thereof. Background technique [0002] At present, with the rapid development of urban construction and the increasingly strong atmosphere of modernization, people use pipe piles more and more widely. The most common application is in construction docks, buildings, road facilities and industrial production rooms. The root cause is some characteristic factors of the pipe pile itself. The product structure of the pipe pile is relatively reasonable, and the specifications and varieties are complete, which can be effectively used in different industries. , has been favored and praised by many users. The strength of pipe pile concrete is also very high, with stable characteristics, safe and reliable during use, not easy to bend, and can penetrate dense sand laye...
