Installation device and method for in-situ lateral earth pressure cell of manual hole digging pile

The invention discloses a manual hole digging pile in-situ lateral earth pressure cell installation device and method.The manual hole digging pile in-situ lateral earth pressure cell installation device comprises a pressure cell installation mechanism for fixing an earth pressure cell and a threading pipe, the threading pipe comprises a C-shaped inner pipe and a C-shaped outer pipe, the C-shaped inner pipe can rotate in the C-shaped outer pipe, and the C-shaped inner pipe and the C-shaped outer pipe are matched with a clearance; wire notches are correspondingly formed in the C-shaped inner pipe and the C-shaped outer pipe; and a plurality of fixed clamping seats are arranged outside the C-shaped outer pipe. The method comprises the steps of S1 to S6 and the like. The pressure box mounting mechanism can effectively fix the position and the stress direction of the soil pressure box, and the validity of detection data is ensured. The earth pressure box lead is led to the ground through the threading pipe, and th
