Abstract

The invention provides a porous occlusive pile drilling machine and a construction technology thereof. The porous occlusive pile drilling machine comprises a vehicle body counterweight, a main winch, and a power head or a support and a plurality of power heads, wherein a plurality of drilling rods and a plurality of drilling buckets are arranged on the power head, the drilling rods correspond to the drilling buckets one by one, the distance between the two adjacent drilling buckets in the drilling buckets is shorter than the maximum distance between two points in a drilled hole corresponding to each drilling bucket, and the tensions of the vehicle body counterweight and the main winch are matched with the power head, the drilling rods and the drilling buckets; at least one drilling rod and at least one drilling bucket are arranged on each power head, and the distance between the two adjacent drilling buckets in the drilling buckets on the power heads is shorter than the maximum distance between two points in the drilled hole corresponding to each drilling bucket; and the tensions of the vehicle body counterweight and the main winch are matched with the power heads, at least one drilling rod and at least one drilling bucket. The construction efficiency of the drilling machine can be effectively improved.

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...
