A porous secant pile drilling rig and construction technology thereof are disclosed. The porous secant pile drilling rig comprises a body weight (1) , a main winch and one power head (3); multiple drill pipes (5) and multiple drilling buckets (7) are installed on the power head (3); multiple drill pipes (5) and multiple drilling buckets (7) are one-to-one; the distance between two adjacent drilling buckets of multiple drilling buckets (7) is less than the maximum distance between two points in each drill hole corresponding to each drilling bucket respectively; both the body weight (1) and the tension of the main winch adjust to the power head (3), multiple drill pipes (5) and multiple drilling buckets (7). Otherwise, the porous secant pile drilling rig also comprises a support frame (9) and multiple power heads (3'), and at least one drill pipe (5') and at least one drilling bucket (7') are installed on each power head; the distance between two adjacent drilling buckets of drilling buckets (7') on multiple power heads(3') is less than the maximum distance between two points in each drill hole corresponding to each drilling bucket respectively; both the body weight (1) and the tension of the main winch adjust to multiple power heads, at least one drill pipe and at least one drilling bucket. The drilling rig can effectively improve construction efficiency.
Description
technical field [0001] The invention relates to the field of drilling rigs, in particular to a porous occlusal pile drilling rig and a construction process thereof. Background technique [0002] With the vigorous development of my country's infrastructure construction, multi-storey basements are often designed in high-rise buildings or subway stations to be used as parking garages, air-conditioning refrigeration and heating machine rooms, and civil air defense projects. At the same time, the large amount of earth excavated to build the basement can also reduce the vertical pressure of the entire building on the foundation and foundation. During construction, the excavation of the multi-storey basement forms the deep foundation pit of the building. Various damages often occur in deep foundation pits, such as landslides, landslides, water seepage, and even cause accidents such as the collapse of surrounding buildings, which leads to the current hot project - foundation pit su...
