Abstract

The invention discloses a precast pile sinking device and a construction method thereof. The pile sinking device comprises a movable equipment platform, wherein a pile planting device is mounted in the center of the equipment platform; a hoisting device and a drilling frame base are arranged on the equipment platform; a drilling frame platform is mounted on the drilling frame base; a main mast is vertically hinged to the drilling frame platform; two drilling machine main machines for driving a drilling rod to rotate are arranged on the main mast; a winch which is connected with the drilling machine main machines through steel wire ropes and is used for driving the drilling machine main machines to move up and down along the guide direction of the main mast and a power distribution box for distributing power to all power utilization units on the equipment are also mounted on the drilling frame platform; and the main mast is hinged to two main mast supports. The construction method of the precast pile sinking device comprises eight process steps. The precast pile sinking device is small in number of construction equipment, small in occupied area, high in construction efficiency and reliable in process, and can meet the process requirements of drilling and pile planting.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction, in particular to a prefabricated pile sinking equipment and a construction method thereof. Background technique [0002] Existing prefabricated pile planting process has two sets of large-scale construction equipment, a pile frame suspension drilling rig forms a pile machine system, carries out drilling and bottom expansion grouting, and an equipment carries out pile planting. There are currently two popular construction techniques for this type of equipment in the market, and the construction process is as follows: [0003] Process 1: The main mast of the drilling rig suspended by the pile frame is relatively low, and a drilling rig equipment is suspended from the main mast. The drilling rig is used for drilling. When the drilling depth is greater than the length of the drill pipe, the drill pipe needs to be spliced ​​and disassembled. Because the main mast is low, the dept...
