Pile sinking device and construction method thereof

Abstract

The invention relates to the field of foundation engineering construction, in particular to a pile sinking device. The pile sinking device comprises a construction platform connected with a walking mechanism, a pile sinking device body connected to the construction platform and an electricity box; a drilling device is arranged on the construction platform; a pile hanging unit which is suitable formoving a pile body to the pile sinking device body is arranged on one side of the pile sink device body; and the electricity box is connected with an external power source and provides electricity for the walking mechanism, the drilling device, the pile sinking device body and the pile hanging unit which are arranged on the construction platform. According to the pile sinking device, the structural design is reasonable, drilling equipment and pile sinking equipment are organically combined and improved and designed onto a same construction platform, and the problem that the mutual cooperatingefficiency of traditional two sets of equipment is low is solved; and the use is simple and convenient, the fault rate is low, the drilling-pile-pressing efficiency is effectively improved, meanwhile, an improved construction method is matched, the condition of hole collapse after a drilling rod is removed is avoided, the pile sinking success rate is greatly improved, efficient and sequential operation of pile pressing construction is ensured, and construction period delay caused by equipment fault is avoided.

Description

Technical field: [0001] The invention relates to the field of foundation engineering construction, in particular to a pile sinking device and a construction method thereof. Background technique: [0002] At present, when prefabricating piles at the construction site, the construction method of drilling first and then pressing piles is mostly used. However, this construction method often requires two sets of equipment to be used together. The drilling equipment is pre-drilled, and the equipment is moved after drilling. At the next drilling position, the pile driver cooperates with the movement to press the pile body into the drilling hole. The disassembly and transportation costs of the two sets of equipment are relatively high, and the construction space is occupied. During the construction process, due to the complex soil conditions, the drill pipe is prone to deflection and hysteresis when drilling. After the drill pipe is removed, the borehole is also prone to collapse, w...
