Abstract

The invention discloses a drilling pile casing guide device provided with calibration mechanisms and a control method. The device comprises an upper support, a lower support, a plurality of supporting columns arranged between the upper support and the lower support, a controller, a digital level, a laser emitter, a laser receiver and a horn. The upper support comprises a rectangular frame, two transverse rods arranged in the rectangular frame, two longitudinal rods connected with the two ends of the two transverse rods correspondingly, the longitudinal calibration mechanisms and the transverse calibration mechanisms, wherein the longitudinal calibration mechanisms are arranged on the transverse rods and borders, corresponding to the transverse rods, of the rectangular frame, and the transverse calibration mechanisms are arranged on the longitudinal rods and borders, corresponding to the longitudinal rods, of the rectangular frame. The controller is electrically connected with the digital level, the laser emitter, the laser receiver and the horn. The lower support is identical with the upper support in structure. The device and the method have the characteristics of being capable of effectively controlling the perpendicularity of drilling pile casings and high in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of bored pile construction, in particular to a drilling casing guiding device provided with a calibration mechanism which can effectively control the verticality of the drilling casing and improve construction efficiency. Background technique [0002] Drilling casing insertion is an important process in the construction process of bored piles. At present, the mainstream drilling casing insertion is mainly controlled by two theodolites in two directions at a 90-degree right angle, and must be monitored throughout the insertion process. , very low efficacy. Even simple visual inspection and direct insertion can easily cause the verticality of the drilling casing to not meet the requirements, exceeding the 1% requirement of the specification, which may cause the drill bit to be stuck by the bottom of the casing. [0003] The lowering speed of the drilling casing is extremely slow, the efficiency is extremely l...
