Description

technical field [0001] The invention relates to the technical field of pile foundation mechanical equipment control, in particular to a monitoring and control system and method for a core-core composite pile. Background technique [0002] The core composite pile (also known as the rigid composite pile) technology based on the unidirectional rotation mixing pile technology was introduced into my country from Japan, and it began to be used in the field of civil engineering at the beginning of this century. The core-core composite pile can solve the technical problems of the PHC pipe pile's construction soil squeezing effect and the inability to drive into dense sandy soil, hard plastic cohesive soil and weathered rock and soil layers. [0003] Over the years, the engineering application results of core-core composite piles show that the quality of its engineering depends on whether the engineering quality of deep mixing pile construction can be controlled, and whether the PHC ...

AI Technical Summary

Problems solved by technology

[0004] In the engineering construction of the core composite pile, the existing deep-layer mixing pile engineering technology relies on the unidirectional rotating mixing construction equipment and construction technology, which usually cannot effectively control the construction quality of the mixing pile, and the solidified soil pile body is often stirred unevenly. , The strength distribution is not uniform, and it is easy to cause the sticky drill to stick to the drill when constructing in the cohesive soil, and the serious engineering quality problem that the strength of the solidified soil pile body cannot meet the design requirements, and will lead to the bearing capacity of the core composite pile foundation. Engineering Safety Problems of Lowering and Settling Exceeding Standards

However, the existing construction quality control needs to be implemented by pile driver operators, thus introducing human factors

[0005] At present, the construction of mixing piles and PHC pipe piles is realized by manual operation of the pile machine by the machine operator; since there is no intelligent monitoring and control equipment on the pile machine, the machine hand cannot perceive the change of the ground during the drilling and mixing construction, and cannot accurately control it The lifting speed and rotation speed of the drilling tool cannot accurately control the amount of grout sprayed at each depth of the mixing pile, and all the manual control actions of the pile driver cannot be quantitatively implemented, which leads to a large number of construction quality accidents of the mixing pile and the core composite pile. and root causes of security incidents
