Study On Composite Shaft Lining With Steel Skeleton And Steel Reinforced Concrete

With the rapid development of China's economic construction, energy demand growing, the growing problem of energy shortage, new energy, the energy needed to fully replace the traditional time. On the composition of our present view of energy, coal energy is still a major player. Therefore, a number of large new coal mine is the urgent task. However, with the depletion of shallow coal resources, to the deep excavation in the deep layer of the table land mines in the construction of the new building will be mine important issues need to be solved. With the increase of surface soil thickness, wall design appeared difficult to solve the problem, either the inner or outer shaft wall designIn considering the pressure and frost heave in the full pressure design wall thickness would appear too large or too high concrete strength. By freezing construction, wall thickness of the frozen layer increases greatly increased the radius of the construction is to extend the duration, resulting in substantial increase in project cost.In order to solve the Deep Overburden wall lining structure and design, first proposed steel reinforcing plate concrete support wall. This article from the following aspects, to the steel skeleton concrete retaining wall plate study.⑴wall construction method to conventional steel frame with steel reinforced concrete retaining wall construction methods are compared to explain the new support method's advantages in construction, and new ways to use the process may bring some of the construction questions and responses.⑵finite difference method are two cases to simulate the force on the wall. Obtained the same in the two wall thickness, steel reinforced concrete wall steel skeleton of steel consumption is a reinforced concrete wall of 1.49 times, 1.43 times the carrying capacity increased; to bear the same stress situation, concrete steel reinforcing plate composite wall of reinforced concrete shaft wall thickness is reduced more than 23.5% of the conclusions.⑶described steel framing steel concrete composite wall, in the freezing, driving, support the unique advantages such as.In this paper, the bottom wall 10 meters for the study, soil layer is relatively simple to come up with more targeted results, should be considered in a broader more and more elaborate.
