Multilayer karst development zone pile foundation engineering construction method
The invention relates to the technical field of pile foundation engineering, in particular to a multilayer karst development zone pile foundation engineering construction method. The method comprises the steps that a calculation model and a calculation formula are firstly built based on the structural mechanics and geology theory to obtain karst zone pile foundation construction prospecting depth to determine prospecting depth and prospecting thoughts; bed rock characteristics are prospected to form a prospecting result according to the prospect thoughts; a geological fault zone distribution diagram and a proposed building and karst development zone relative position relational graph are drawn according to the prospecting result; then the construction sequence of ground pile foundations is determined with each proposed building as a unit, the construction sequence of the ground pile foundations of the proposed buildings is then divided on this basis, and different kinds of grouting pretreatment are carried out on the pile foundations in batch by different levels; and then grouting construction is carried out on the karst development zone foundation of each building. Construction is carried out according to the multilayer karst development zone pile foundation engineering construction method, and surface collapses, casualties and financial losses caused by construction can be effectively avoided.
