Description
Technical Field
The utility model relates to a real standard field of bridge lower part combined test and simulation pile foundation in the experimental supporting facility of teaching.
Background
The comprehensive test training field for the bridge substructure is a construction task in construction projects of an exemplary training base for higher-duty education in Henan province and construction of exemplary colleges and universities of higher-duty education brands in Henan province, is perfect and supplementary of the experimental training function in schools, is also an important content for the construction of a bridge intelligent monitoring and safety early warning Henan engineering laboratory and a building structure reinforcing material Henan engineering laboratory, and more importantly is a production and research base of the Wuhan geotechnical research institute of Chinese academy of sciences. Through study, let site operation personnel know check out test set's use, know the common defect of pile foundation to can utilize corresponding check out test set to detect out the defect in the real pile foundation. The common defects of the prior pile foundation include cavities, segregation, mud and soil clamping, laitance, sediment, pile breakage, diameter shrinkage, diameter expansion, inclination of an acoustic pipe, pipe wrapping and the like. The reason for generating the void defect is that partial unqualified concrete in concrete pouring is seriously separated and loosened to form a void; the segregation defect is caused by that the concrete is not uniformly stirred, the transportation path is too long, the guide pipe leaks water, and the concrete is soaked by water to form segregation; the reason for the defect of mud inclusion is that during the pile filling process, mud blocks fall into the hole or the hole wall is unstable and falls into concrete to form the defect; the floating slurry defect is caused by that the water pressure of the concrete poured to the pile top position is low, so that the water content of the concrete at the pile top position is large and the compactness is low; the sediment defect is caused because the hole cleaning does not meet the standard requirement and the mud proportion is overlarge; the pile breakage defect is caused by that the buried depth of the guide pipe is calculated wrongly in the pile filling process, so that the buried depth of the guide pipe is too shallow or the guide pipe is pulled out and lifted to leak, or the guide pipe is blocked due to poor concrete segregation fluidity, so that the pile breakage is formed; the reason for the shrinkage defect is that the shrinkage is formed after the hole wall is unstable or the soft plastic soil expands when meeting water; the reason for the diameter expansion defect is that the hole wall is unstable and collapses to form diameter expansion; the inclination defect of the sounding pipe is caused by the fact that the sounding pipe is inclined due to the fact that the reinforcing cage is not standardized during manufacturing; the reason for the defect of the pipe is that the acoustic pipe is wrapped by mud blocks or foreign matters.
In the actual engineering, the general underground concealed engineering of pile foundation's reason, whole drilling to and the process of pouring into and mix the pore-forming concrete all go on under water, and all site operation personnel are limited to theoretical knowledge and construction experience to the foundation pile yet, are unfavorable for directly perceived teaching practice. Therefore, the defects of foundation pile construction and pile forming conditions including the later ultrasonic detection condition are completely displayed on the ground, and the overall visual display is more favorable for teaching training and skill training and examination.
