Abstract

The invention discloses an intelligent pile head breaking method and device. The method comprises the steps that setting out is conducted through a measuring instrument, and the elevation position of the top of a pile head is obtained and marked with a marking pen; the thickness of a pile foundation protective layer and positions of main steel bars of a reinforcement cage are detected by adoption of a reinforced protective layer tester; concrete is cut along a second annular rail through a cutting machine, and main steel bars of the reinforcement cage are protected against damage; a rotating hydraulic drill is controlled to perform drilling in positions away from the main steel bars of the reinforcement cage; after drilling forming is completed, a hydraulic splitting machine is adopted for pre-splitting the pile head; and the pre-split pile head is hoisted out of a foundation pit. The device comprises an operation room, a hoisting system, a power system, a hydraulic system, a detecting system, a drilling system, a pre-splitting system and an intelligent control system. The device provided by the invention is simple in structure and low in machining and manufacturing cost, intelligent operation is completely achieved, input for pile heads of a pile group in a large-area breaking operation procedure and site human resources is greatly reduced, the construction and production efficiency is improved, quality control is improved, and the intelligent pile head breaking method and device are safe and reliable.

Description

technical field

[0001] The invention relates to the technical field of one-time intelligent removal of overcast pile heads in bridge pile foundation engineering, in particular to a removal method and device integrating cutting, drilling and pre-cracking of pile heads. Background technique

[0002] In bridge pile foundation engineering, there are many advanced application technologies and mechanical equipment in the construction technology of removing pile heads at home and abroad. The most common construction methods and mechanical equipment are analyzed: what is seen at present is usually manual use of pneumatic picks to peel off pile heads After the reinforcement, the rest of the pile heads are hoisted away. Manual use of pneumatic picks to peel off pile heads can easily cause defects such as difficult operation, poor environment, and long time consumption, which greatly increases construction costs. It is only suitable for single-pile pile head removal construction of sma...
