Anti-overturning construction method for existing tower crane under working condition of adjacent foundation piles
The invention relates to the technical field of building engineering design and construction crossing, in particular to an anti-overturning construction method for an existing tower crane under the working condition of adjacent foundation piles. The anti-overturning construction method for the existing tower crane under the working condition of adjacent foundation piles includes the following steps of firstly, calculating the counter force of a foundation of the tower crane; secondly, checking and calculating the bearing capacity of an H-shaped steel beam; thirdly, checking and calculating theuplift bearing capacity of a steel pipe pile; fourthly, checking and calculating the welding seam bearing capacity of the steel pipe pile; fifthly, welding the H-shaped steel beam and the steel pipepile; and sixthly, punching and grouting the steel pipe pile. The anti-overturning construction method for the existing tower crane under the working condition of adjacent foundation piles has good stress performance, is safe and convenient in construction, shortens the construction period, reduces the construction cost, solves the key technical problems of anti-overturning design and constructionof the existing tower crane under the working condition of adjacent foundation piles, meets the green construction requirement of high efficiency and energy conservation, and has great popularizationand application value.
