Accurate pile feeding method and system of pile driver

Abstract

The invention relates to the field of building construction, and discloses an accurate pile feeding method and system of a pile driver. The method comprises the steps: obtaining the elevation Ah of apreset pile top altitude point A; determining the position of a mark point B, wherein the position of the mark point B is higher than the pile top altitude point A; determining the position of a markpoint D; obtaining the elevation Dh of the mark point D, determining the height difference between the mark point D and the mark point B, and determining the elevation Bh of the mark point B through the Dh and the height difference; determining a pile rod marking position numerical value Lc according to the Ah and the Bh; determining a mark point C according to the Lc; and acquiring coincidence condition information of the mark point C and the mark point B, and determining whether pile feeding is completed or not according to the coincidence condition information. The system comprises an information input unit, a signal output unit, a signal acquisition unit, and a processing and storage unit. The method and the system have the effect of reducing deviation.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for accurately sending piles by a pile driver and a system thereof. Background technique [0002] At present, sending piles refers to driving prefabricated concrete pipe piles into the foundation until reaching the specified soil layer. [0003] In the existing pile sending process, the position of the last pile is manually judged. When the pile enters the soil, the worker measures the distance between the upper surface of the last pile and the ground to determine whether the pile has reached the ground. Book a spot. [0004] The above-mentioned existing technical solutions have the following defects: because it is difficult for the pile driver to send the pile to the predetermined position at one time, the workers need to measure the position of the pile multiple times, and the pile can be moved relatively quickly through the multiple pile sending operati...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: because it is difficult for the pile driver to send the pile to the predetermined position at one time, the workers need to measure the position of the pile multiple times, and the pile can be moved relatively quickly through the multiple pile sending operations of the pile driver. Accurately arrive at the predetermined position, but due to manual measurement, the measured value will inevitably have a certain deviation from the actual value, resulting in a certain deviation between the actual position of the pile and the predetermined position.
