Description
Technical Field
The invention relates to the technical field of building construction, in particular to a novel cfg pile quality detection system.
Background
The CFG pile is an abbreviation of English Cement Fly-ash Gravel, and means a Cement Fly ash Gravel pile, which is a variable-strength pile with certain strength and is made by mixing Gravel, stone chips, sand and Fly ash with Cement and adding water and mixing the mixture by various pile forming machines. The CFG pile is a low-strength concrete pile, can fully utilize the combined action of bearing capacity of soil among the piles, can transmit load to a deep foundation and has better technical performance and economic effect.
Bond strength piles are representative of composite foundations, and are used in high-rise and super high-rise buildings. The CFG pile is a cement fly ash gravel pile for short (namely, cement fly ash gravel pile). It is a high-adhesion-strength pile formed by mixing cement, fly ash, broken stone, stone chips or sand with water, and a composite foundation formed by the pile, soil between piles and mattress layers. The CFG pile composite foundation is connected with the foundation through the mattress layer, and whether the pile end falls on a common soil layer or a hard soil layer, the soil between the piles can be guaranteed to participate in the work all the time. Because the strength and modulus of the pile body are larger than those of the soil between the piles, the stress of the pile top is larger than the surface stress of the soil between the piles under the action of load. The piles can transmit the borne load to a deeper soil layer and correspondingly reduce the load borne by soil among the piles. Therefore, the bearing capacity of the composite foundation is improved and the deformation is reduced under the action of the pile, and in addition, the CFG pile is not provided with ribs, and the pile body utilizes industrial waste fly ash as an admixture, so that the construction cost is greatly reduced.
The cfg pile plays a vital role in the building construction process, so the quality detection of the cfg pile is also an indispensable process, and a novel cfg pile quality detection system needs to be developed for detecting the quality of the cfg pile.
