Please refer to fig. 1, which is a schematic structural diagram of a soil mass layered settlement and horizontal displacement composite measuring device 10 according to a preferred embodiment of the present invention. The soil body layered settlement and horizontal displacement composite measuring device 10 comprises a cable 13 with scales, a composite reading instrument 12 and a composite probe 11. One end of a cable 13 with scales is connected with the composite probe 11, and the other end is connected with the composite reading instrument 12, so that the composite reading instrument is used for transmitting electric signals and is also used as a depth measuring ruler. The composite measuring device 10 is operated in the inclinometer and settler pipe 20 buried in the soil body in the axial direction (up-down direction) to perform soil body stratified settlement and horizontal displacement measurement, as shown in fig. 2.
The composite probe 11 has a probe cavity 111, a settlement gauge probe 112, an acceleration sensor 113, a bottom cushion 115, a pulley assembly 114 and an outside of the probe cavity 111 are arranged in the probe cavity 111. A settlement gauge probe 112, an acceleration sensor 113 and a bottom cushion 115 are located at the top, middle and bottom respectively within the composite probe 11. The pulley assembly 114 is disposed at the periphery of the probe cavity 111 and contacts the inner wall of the inclinometer and sedimentation tube 20 to assist the compound probe 11 in its travel. The composite probe 11 moves in a crisscross guide groove in the inclinometer and sedimentation tube 20, which serves as an up-and-down sliding track for the pulley assembly 114 outside the probe cavity 111.
A settlement gauge probe 112 is located at the top end of the probe cavity 111. When the composite probe 11 moves along the guide groove in the inclinometer and settling tube 20, when the settlement gauge measuring head 112 reaches the buried position of the settlement ring 30 in the soil layer, the magnet embedded in the inner side of the settlement ring 30 triggers the magnetic induction element in the settlement gauge probe 112, the formed electric signal is transmitted to the composite reading gauge 12 through the cable 13, the buzzer of the composite reading gauge 12 makes a sound, and at the moment, the position data of the settlement gauge measuring head 112 can be read through the corresponding scale on the cable 13, and the position data is also the position data of the settlement ring 30 observed at this time.
