Excavation of gravel layer retaining soil column Because of the high geological hardness of central gravel, mechanical drilling has not been effective, and the Jinmen geology is mostly granite rock formation. The construction plant is actively looking for new construction methods to solve the construction dilemma.
This study will analyze the efficiency of pneumatic drilling construction method with traditional excavation method and traditional machine tool method and manual excavation. The analysis content uses artificial retaining column and artificial well artificial excavation, rock layer blasting method and pneumatic drilling construction method. The cost and safety, construction rate, and noise measurement are analyzed, and the rate and integrity of the pre-dwelling pile method are compared.
This paper introduces the pneumatic drilling and excavation construction method to overcome the special underground gravel layer geology and Jinmen rock geology in some areas of Taiwan, and the special construction method of underground excavation of dredging and retaining pile foundation construction, which needs to be artificially deep underground, developed with rapid construction. Safety, energy saving work methods.
