Automatic detection device and detection method for deformation of narrow and long foundation pit

Abstract

The invention discloses an automatic detection device and detection method for deformation of a narrow and long foundation pit, and relates to the technical field of foundation pit construction. The automatic detection device comprises a to-be-detected foundation pit, guide pipes pre-buried at two sides of the to-be-detected foundation pit, and a monitoring mechanism arranged through the guide pipes; the device is characterized in that the monitoring mechanism comprises a traction rope installed in the guide pipe, an inclinometer installed on the traction rope and a recording and reading device, and a transmission wire is arranged at one end of the inclinometer; traction devices are arranged at the two ends of the guide pipe, one end of the traction rope is connected with the inclinometer, the other end of the traction rope is connected with one traction device, one end of the transmission wire is connected with the traction device away from one end of the traction rope, the inclinometer is pulled back and forth through the traction devices, repeated detection is achieved, and the traction rope does not need to be installed repeatedly. The detection efficiency is improved.
