Embodiment 1

[0032] like figure 1 and figure 2 As shown, a layered sedimentation monitoring device includes a sedimentation tube 1, at least one sedimentation magnetic ring 2 and at least one displacement sensor 3;

[0033] The sedimentation magnetic ring 2 is arranged outside the sedimentation tube 1 so as to slide along the axis of the sedimentation tube 1, and the sedimentation magnetic ring 2 is fixed in the layer to be monitored; and when the layer to be monitored settles, the sedimentation magnetic ring 2 follows the layer to be monitored. synchronized movement;

[0034] The displacement sensor 3 is arranged in the sedimentation tube 1, and the monitoring end 6 of the displacement sensor 3 is connected to the sedimentation magnetic ring 2 in a non-contact manner; when the sedimentation magnetic ring 2 moves, the monitoring end 6 of the displacement sensor 3 is connected to the magnetic sedimentation ring 2. The subsidence magnetic ring 2 moves synchronously, and the displacement s...

Embodiment 2

[0052] The difference between this embodiment and Embodiment 1 is that the sensor body 4 is fixed in the settling tube 1 through the first connector, and the sensor body 4 is communicatively connected to the collector through a wireless transmission module. Wherein, the first connector can be but not limited to a steel rope, one end of the steel rope is fixed on the top of the sensor body 4, and the other end is extended to the outside of the settling tube 1 to be fixed; the connection between the sensor body 4 and the collector can be but not limited to Communicate via WIFI / 5G / 4G.

Embodiment 3

[0054] This embodiment is a construction process of the layered settlement monitoring device described in Embodiment 1 or Embodiment 2, including the following steps:

[0055] S10. Drilling the monitoring hole 11: Drill the monitoring hole 11 according to the designed depth, and flush the dirt in the monitoring hole 11 after drilling; the depth of the monitoring hole 11 should extend 1m below the actual rock surface line. The rinsing time is 20-40min, preferably 30min. If the hole is not formed and is easy to collapse, the mud wall can be used or the casing can be placed on the hole wall.

[0056] S20. Settlement tube 1 pipeline installation: put the monitoring hole 11 in the order of the bottom of the tube, the settling tube 1 and the top cover of the tube; after the settling tube 1 is in place, select the corresponding number of 6 settling magnetic rings according to the number of 6 measuring points 2; Install 6 subsidence magnetic rings 2 to the measuring points in sequenc...

Abstract

The invention discloses a layered settlement monitoring device. The layered settlement monitoring device comprises a settlement pipe, at least one settlement magnetic ring and at least one displacement sensor, the displacement sensor is arranged in the settlement pipe, and the monitoring end of the displacement sensor is in non-contact connection with the settlement magnetic ring; the invention further discloses a construction technology of the layered settlement monitoring device. The construction technology comprises the steps of monitoring hole drilling, settlement pipe pipeline installation, displacement sensor installation and the like. Non-contact linkage between the settlement magnetic ring and the monitoring end is realized through magnetic force, the settlement pipe does not need to be perforated and linkage between the settlement magnetic ring and the monitoring end is realized through a connecting piece during settlement monitoring, the sealing performance of the settlement pipe can be effectively ensured, and the monitoring hole does not seep into the settlement pipe; the service life of electronic components in the settlement pipe is effectively guaranteed, and the settlement pipe can be buried in a soil layer / rock stratum for a long time for monitoring.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering monitoring, in particular to a layered settlement monitoring device and a construction process thereof. Background technique [0002] Soil layer settlement monitoring is mainly to monitor the settlement of soil at different depths and layers. The whole monitoring system consists of sedimentation instrument, sedimentation tube, sedimentation ring and other supporting equipment. Among them, the subsidence instrument is the core equipment for monitoring the soil stratified settlement. According to the different principles of monitoring methods, it is divided into: deep punctuation level method, magnetic ring settlement instrument method, fixed rod method and serial layered settlement measurement and other monitoring methods. In the monitoring of soil stratified settlement, the rod-type multi-point displacement and settlement instrument was initially used as the main monitoring inst...
