Pile tip and pile side hydration heat prediction and control method in static drilling root planting pile planting process
The invention relates to a pile end and pile side hydration heat prediction and control method in a static drilling root planting pile planting process, which comprises the following steps of: 1) calculating initial temperatures of all underground depths before construction according to readings of a surface temperature sensor and a ground temperature gradient measured by a ground survey; 2) collecting temperature change calculation parameters of the static drilling rooted pile; 3) calculating the temperature variation caused by hydration reaction at each numbered node of the pile end and the pile side; 4) according to the initial ground temperature and the temperature variation at each position, calculating the final temperature at each numbered node of the pile end and the pile side; 5) recording all pile end and pile side nodes exceeding 35 DEG C, and sending signals to the controller; and (6) the controller triggers the pile end or pile side hydration heat control system to adjust the temperature of the temperature abnormal node according to the node position. According to the method, the hydration heat of the pile end and the pile side in the pile planting process can be predicted in real time, local accurate control over the hydration heat is achieved, and therefore the stability and the bearing capacity of a pile foundation are guaranteed.
