Description

Pile foundation construction hole depth measuring device Technical Field The utility model belongs to the technical field of measuring devices, and particularly relates to a pile foundation construction hole depth measuring device. Background When the pile foundation is constructed, pile foundation holes are required to be formed in advance, and the depth of the pile foundation holes directly influences the stability of pile foundation later-stage burying. In the related art (publication number is CN 218496002U) discloses a pile foundation hole depth measuring device for pile foundation construction, including ladle body and smooth bucket, the right side fixedly connected with horizon rule of ladle body, the upper end middle part fixedly connected with motor of ladle body, the outer wall fixedly connected with connecting rod of motor lower extreme drive end, connecting rod lower extreme fixedly connected with lifting ring, the inside threaded connection of lifting ring has the lifter plate, ladle body bottom middle part is provided with the sliding tray. The supporting leg is adjusted at first, can observe through the horizon rule, if unbalanced accessible knob adjusts and watches the horizon rule, adjusts always until the ladle body is in steady state, can not incline like this and lead to the inaccurate condition of reading, reduce the error, start the motor, motor pivoted in-process drive connecting rod and lifting ring rotate to the fixed scale plate of lifter plate go up and down, convenient operation has avoided taking time and energy with manual measurement, has promoted work efficiency.
