Abstract

The invention discloses construction equipment based on synchronous drilling and precast pile splicing and a construction method thereof. The equipment comprises an equipment main platform provided with drilling and pile planting holes, and a lifting device and a main mast are arranged on the equipment main platform; six track plates are arranged on the main mast, one drilling machine is arranged on each of the first track plate and the second track plate, and two pile clamping devices are arranged on each of the third track plate and the fourth track plate; the two pile clamping devices on the third track plate are the first pile clamping device and the second pile clamping device, and the two pile clamping devices on the fourth track plate are the third pile clamping device and the fourth pile clamping device; the third section of precast pile and the fourth section of precast pile are spliced on the fourth track plate while the drilling machine on the second track plate drives a drill rod to drill holes; and the first precast pile section and the second precast pile section are spliced on the third track plate while the drilling machine on the first track plate drives the drill rod to drill holes. The equipment construction method is simple and efficient, and the pile planting quality can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction, in particular to construction equipment and a construction method based on synchronous drilling and splicing of prefabricated piles. 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 disassemble...
