This invention relates to a pile foundation positioning and anti-deviation structure for pile foundation engineering, belonging to the field of pile foundation positioning technology. It includes a base, with mounting columns symmetrically connected to the four corners of the base. A support seat is connected to a fixed seat above each mounting column. The outer protrusion of the mounting column is fixed to the fixed seat. A support seat is installed above the fixed seat, and a platform is installed above the support seat. A movable sleeve is installed at the central opening of the platform's internal cavity. Through the cooperation of the platform, the spherical movable sleeve, and the guide tube, gravity is used to adaptively keep the guide tube vertical, allowing for rapid adaptation to uneven ground. Simultaneously, an oil adjustment and fixing component is included. The oil is pushed according to the pile column diameter to adjust the meshing position of the transmission gear, adapting and adjusting the transmission speed of the gear, thereby adjusting the drilling depth of the screw groove column. A larger diameter results in deeper drilling, further improving the pile foundation positioning accuracy.

This invention discloses a vibration data acquisition device and event identification method for deep-earth drilling rigs. The device includes an interface board, a connection board, and a main control board connected in sequence; the interface board is also connected to a power supply and sensors respectively. This invention provides a vibration data acquisition device and identification method that enables synchronous acquisition of multi-point vibration data and real-time fault state classification. Through GPS+OCXO time synchronization, magnetic coupling isolation, and multi-channel RS-485 digital sensor access, event identification is based on the coupling relationship of three-axis vibration data from the same channel, performing joint dimensionality reduction and feature extraction to form a fused representation before LSTM inference. This avoids false alarms and missed alarms caused by single-axis thresholds / single-axis features, improving the reliability of identifying abnormal events under complex working conditions.

This invention relates to a method for predicting mudstone expansion and blockage in deep boreholes and optimizing borehole operation scheduling. The method divides boreholes into sections based on depth and assigns a risk budget item to each section, including at least one of the following: the number of precursor windows, the duration of a phase, and the number of invertible events. Within a sliding time window, at least two of the following parameters are collected: torque, pump pressure, returned material parameters, and mechanical drilling rate. These parameters are compared with a baseline to form primary evidence, which is then combined with exclusionary evidence to identify precursor windows. When a precursor window occurs consecutively for a set number of times, the blockage phase is advanced and a predetermined exploratory action is performed. If the pump pressure or torque does not recover to the baseline's allowable range within a set time limit, it is determined to be an invertible event. The corresponding budget is deducted based on the number of precursor windows, phase duration, and number of invertible events. When any budget is exhausted, a borehole operation deadline and urgency level for that section are generated. The borehole operation needs of multiple sections are prioritized by deadline. When the difference in deadlines is not greater than a threshold, a scheduling plan is generated by combining urgency level and scheduling constraints.
