Abstract

The invention discloses a pressing type drilling technology based on negative feedback temperature adjustment. A machine body and two supporting columns symmetrically and fixedly connected to the left end and the right end of the bottom end of the machine body are included; and a first cavity is formed in the machine body. According to the pressing type drilling technology based on negative feedback temperature adjustment, the equipment structure is simple, operation is convenient, automatic ground drilling is achieved, all procedures are matched with one another and do not affect one another, the temperature is detected in real time through a negative feedback adjusting system, then a drill bit can be continuously cooled in the drilling process, drilled dust can be removed, the practical performance and efficiency of a device are improved, waste of manpower and material resources is effectively avoided, and therefore cost is greatly reduced.

Description

technical field

[0001] The invention relates to the related field of drilling equipment, in particular to a pressure-down drilling process for adjusting temperature based on negative feedback. Background technique

[0002] Drilling equipment has many advantages such as high degree of mechanization, strong stratum adaptability, flexible and fast construction, etc., and is currently the most common and effective technical measure adopted in the deep foundation pit enclosure structure in the upper soil and lower rock strata. The basic parameters of hole pile drilling, along with the whole process of borehole drilling, drilling in the upper soil and lower rock formations with significant differences in physical and mechanical characteristics, the drill bit enters the rock formation from the soil layer, and the torque and speed of the drill pipe will show Significant mutation characteristics, the machine will produce temperature differences during operation, making the operation ...
