Description
Technical Field
The invention relates to the technical field of settlement monitoring, in particular to a settlement monitoring device and a settlement monitoring method.
Background
In high filling projects such as airports, embankments and earth and rockfill dams, in order to predict the sedimentation development trend of filled soil and foundation soil, judging the stability of the projects, it is generally required to monitor the settlement of the filled soil and foundation soil in a layered manner, master the settlement of the soil at different depths and different periods, and related soil layered settlement monitoring methods comprise a deep punctuation level method, an electromagnetic settlement magnetic ring method and the like.
The deep mark leveling method is to adopt a drilling machine to form a hole at a preset position, firmly connect an observation rod with a bottom settlement mark, then sink the observation rod to the position of the preset monitoring point in the hole, protect the observation rod body by adopting a PVC sleeve, and then draw the observation rod body to a certain height above the ground, then measure by adopting a traditional manual leveling height measuring method, but usually only one hole can be used for arranging one monitoring point, if a plurality of soil bodies need to be monitored, a plurality of holes are needed, the drilling engineering quantity is large, and the method is generally only used for the conditions of hard soil bodies and fewer monitoring points and has limited precision.
The method for settling magnetic ring includes vertically forming holes in soil to be measured by drilling machine, sleeving magnetic ring on settling tube at intervals according to the depth of soil to be measured, opening claw-shaped spring piece on magnetic ring after magnetic ring is placed in hole together with settling tube at preset depth, clamping in peripheral soil body to make magnetic ring and peripheral soil body settle synchronously, placing layered settlement instrument probe in settling tube when observing, measuring initial position and settled position of each magnetic ring sequentially, comparing them to calculate layered settlement quantity of soil body. The settlement magnetic ring method is the most commonly used layered measurement technology of engineering, has wider application range than the deep punctuation level method, and has the key and difficult points that the magnetic ring is tightly attached to the surrounding soil body and the settlement is synchronous, and has two main defects in the specific implementation process: firstly, the claw-shaped spring piece on the magnetic ring has limited anchoring force, so that soil on the hole wall is difficult to effectively grip, and the soil filled between the sedimentation pipe and the magnetic ring has larger resistance to the magnetic ring, so that the magnetic ring is difficult to synchronously sediment along with surrounding soil; secondly, in the process of placing the sedimentation pipe and the magnetic ring in the hole, friction is easily formed between the magnetic ring and the inner wall of the monitoring hole, and at the moment, the magnetic ring is easily deviated due to friction, so that the monitoring result is influenced.
