Description
Technical Field
The invention relates to the technical field of layered settlement monitoring of a foundation soil surface layer and a deep part in geotechnical engineering, in particular to an automatic monitoring device for the layered settlement of the foundation surface layer and the deep part of a breakwater revetment.
Background
The method is very important for monitoring the foundation soil body settlement and the layered settlement of the deep soil body in the geotechnical engineering construction process and the operation period, and is also very common in application. In the offshore breakwater revetment construction process, the loading rate is controlled by monitoring the foundation settlement rate, the construction process safety is guaranteed, meanwhile, data support is provided for construction measurement, the soil layer consolidation condition is researched according to the settlement condition, the post-construction settlement is judged, the accuracy of theoretical calculation is verified, and the engineering design reserved height is guided.
The foundation soil body layered settlement monitoring is usually carried out by adopting an electromagnetic layered settlement instrument, the electromagnetic layered settlement instrument is designed according to the electromagnetic induction principle, the depth of a pre-buried settlement magnetic ring is measured by adopting a measuring ruler, the height of an orifice is measured every time, the height of the orifice is converted into the height change of the magnetic ring according to the depth of the magnetic ring, and the settlement amount of each soil layer is calculated. The layered settlement meter in the prior art is mostly used for detecting land soil layer settlement, and the method is manual monitoring, is influenced by personnel, weather and surrounding environment, and cannot ensure the measurement precision and the monitoring frequency.
At present, the automatic monitoring method for the layered settlement on land mainly comprises the following steps:
(1) displacement meter method: the multi-point displacement meters are buried in the monitoring positions in a drilling mode, the anchoring probes are buried in the layering positions in a burying mode, and when the soil layers are settled, the displacement meters are transmitted to the ground surface through the transmission rods to measure the settlement amount of the soil layers. The method is limited by the size of the drill hole, and when too many point positions are monitored simultaneously, the drill holes are required to be added and buried respectively; in addition, the position of the surface sensor needs to be measured by elevation.
(2) The improvement of the traditional electromagnetic type layered settlement meter is that a motor and a control program are additionally arranged on the electromagnetic type layered settlement meter, a measuring cable is regularly wound and unwound in a settlement pipe, and the depth of a magnetic ring is recorded. The method does not consider errors caused by sedimentation and bending deformation of the sedimentation pipe, needs to measure the elevation of the pipe orifice of the sedimentation pipe, is easy to clamp a cable, has high requirements on the surrounding environment, and is not suitable for the underwater environment.
(3) Before the present patent, a patent "layered settlement monitoring device for soil in deep water area" (publication number: CN 204418149U) discloses a layered settlement monitoring device for soil in deep water area, which is based on the principle that a reference pile is driven under the body, a plurality of magnetic displacement sensors are fixed in the reference pile, a magnetic ring is arranged on each measuring rod of the displacement sensors, and the settlement amount is monitored through the change of the magnetic ring. The method has the advantages that the reference pile is required to be stable, the settlement of the surface layer of the foundation cannot be monitored, a thick layer of stones or accumulated sand bags are thrown above the mud surface of the foundation of the breakwater revetment, and when loads are applied to the pile top of the reference pile, the reference pile is bound to be settled, so that the monitoring data are inaccurate.
In addition to the above problems, the breakwater revetment project has a difficulty completely different from land monitoring, for example, the breakwater revetment monitoring foundation is located underwater, and meanwhile, stone blocks or sand bags are required to be loaded above the foundation, so that the elevation of the settling pipe cannot be directly measured every time, and meanwhile, monitoring equipment is easily damaged in the upper load applying process. In addition, in the traditional breakwater bank protection monitoring, the surface layer settlement and the layered settlement are carried out separately, so that the burying workload is large, the instrument protection difficulty is large, and the like, and therefore the invention provides the automatic monitoring device for the surface layer and the layered settlement of the foundation, which is suitable for the characteristics of the breakwater bank protection, and has important significance.
