The Cement Powder Ash From Stove Crushed Stones Stake (CFG) Compound Foundation Construction And Monitor Technique Research

Deepens day by day along with the reform and open policy, international energy day by day scarce, causes the fuel depot construction development to be rapid. The fuel depot development tendency and the characteristic are the reserves big, process unit advanced, the automat city is high. In order to enhance the land utilization ratio, increases the fuel depot reserves, reduces the construction cost, constructs the large capacity pot is the only outlet. The large capacity pot characteristic is the diameter is big, the shell of tank is high, to the tank support request, in particular in the shell of tank differential settlement aspect, has the quite strict limit. Invests in a big way for the effective addressing, the time limit for a project is long, the pot base earlier period and the later period distorts questions and so on monitor difficulty, to the large-scale tank support ground bearing capacity and the distortion research and the monitor, as well as study and use the advanced oil pot ground reinforcement construction technology to have the vital practical significance.In this topic studies (the CFG pile) reinforces the ground construction technology with the cement pulverized coal ash garrulous stone marker is develops in recent years carries on whole reinforcement processing to the large-scale tank support ground the effect extremely ideal one kind of new technology.From the development, the CFG pile application scope more and more is until now widespread, not only it can enhance the ground greatly the security, reduces the construction time limit for a project, may save the project construction cost greatly, but also may periphery prevent the ground appears the submersion, is one kind has the development future and the promoted value weak sub grade reinforcement technology very much. This article unifies the project example, through to CFG pile compound ground design main determination 5 design variable, namely pile long, pile diameter, pile spacing, pile body intensity, mattress level thickness and material analysis and research, proposed the design procedure; To vibrates settling tube non-platoon earth Cheng Zhan and must pushes the earth type to become the hole to attack the pile two kind of different CFG piles to become the hole construction craft, has carried on the CFG pile blend material character and the mixture ratio design calculation;In view of the different construction craft, proposed including the cupping speed, the pile is apart from the determination, executes hits the order, the blend slump and the guard stake long and so on each link different construction quality control measure; Through carries on the entire journey scene monitor to the job location CFG pile single pile supporting capacity and the distortion, thus obtains the CFG pile compound ground supporting capacity determination and the distortion computation mechanism. This article source in project, also is higher than the project, through the discussion and the research from a deeper level knew and has grasped the CFG pile compound ground design theory, the construction and the examination technology, had achieved better the goal which serves for the modern project construction.
