Coring device and method for cement mixing pile test detection

Abstract

The invention discloses a coring device and method for cement mixing pile test detection. The coring device comprises an upward pulling part, a penetration part and a moving part, wherein the upper pulling part consists of a hydraulic motor, a rolling wheel, a fixed steel frame, a support frame, a steel wire rope and a lock catch, the penetration part consists of a hydraulic device, a core barrel,a coring drill barrel and an alloy steel drill bit, the moving part is composed of a crawler belt, a bottom frame body and a hand-held handle; the hydraulic device is adopted to guide the coring drill barrel with an alloy steel drill bit at a lower part of the core barrel to perform cement mixing pile coring operation, stability of the coring process can be ensured, the underground pile foundation can be effectively drilled for coring operation, the hydraulic motor is used for driving the rolling wheel, the coring drilling barrel is pulled out through the steel wire rope and the lock catch, the coring speed can be greatly increased, and a crawler-type device is used for driving a machine body to move for drilling operation. The coring device is advantaged in that the coring machine is convenient to operate, fast in on-site movement, high in operation efficiency and the like and is an ideal device for on-site cement mixing pile coring.

Description

technical field [0001] The invention relates to the technical field of building construction, and more specifically, to a coring device and method for testing and detecting cement mixing piles. Background technique [0002] The detection of cement mixing piles generally adopts the coring method, that is, a core sample is drilled on the pile body with a drilling rig, and the core sample is intercepted to make a test block to detect the length of the cement mixing pile, pile body defects, pile body strength, uniformity and continuity. , so as to determine the quality of the pile body. Among the coring equipment for cement mixing piles, the coring method currently used in China is usually to use an auger bit to drill holes, and when the drill bit reaches the specified depth, press into the ring cutter for sampling. The coring efficiency of this method is low, especially in the construction of large-scale cement-soil mixing piles, the coring of this kind of equipment is too slo...
