The Study On The Factors Of The Bearing Capacity And The Quality Control On The Manual Hole Digging Pile(MHDP)

The overviews of general development conditions, advantages and shortcomings, and relative criterions of quality control and acceptance check of MHDP are given in the beginning of this paper. The loading mechanism of MHDP are discussed through the respectively deep analyses of load transfer of single pile, variation rules of sedimentation, factors that influence single pile's ultimate bearing capacity.The quality control and inspection of MHDP are analyzed mainly. Using the method of AHP theory knowledge and the calculation software, Analyzing the effect of artificial dig-hole pile quality factors. The quality assurance of MHDP are analyzed respectively based on prospecting assess conditions. The bearing capacity of pile tip soil are reflected intuitively by deep plate loading test. Then combined with prospecting data from construction site, issues that should be noted in construction quality control are summarized and summed up, then analyze the reasons, and proposed correlative control methods and measures. Low strain dynamic testing method is an important method in analyzing the integrity of the pile.Finally, by theory with practice, the quality control and inspection of MHDP are applied in real project. Taken construction site of Baoji Petroleum Steel Pipe Plant's residential area 6 for background, through the deep loading test and low strain dynamic testing method, and control the quality of construction site's MHDP effectively.
