Description
Technical Field
The invention relates to the technical field of earthquake observation, in particular to an erection device for field earthquake monitoring shallow hole direct burial.
Background
Geoscience is a comprehensive discipline based on observations. The industrialized and urbanized development of the human society and the surface effect of the earth cause noise to be one of the main factors influencing the seismic observation quality, and the traditional ground seismic observation result is seriously interfered. In order to avoid ground noise interference as much as possible, improve the signal-to-noise ratio of seismic waveform records and obtain more seismic information, deep well seismic observation technology is increasingly applied to seismic observation.
However, at present, good records are difficult to obtain for the erection of most field flowing seismographs, and a field broadband seismograph shallow-hole direct-buried device which is strong in installation practicability, simple and fast in construction method, capable of effectively reducing environmental noise and avoiding the influence of factors such as temperature and airflow on the broadband seismograph is urgently needed, so that the field measurement seismic shallow-hole direct-buried device is arranged under the application number of 'CN201921582205. X', the specific structure of the field measurement seismic shallow-hole direct-buried device is shown in a figure 1, and the application process is as follows:
first, a shallow hole, which is usually a vertical hole of 0.5 to 2 m depth, is drilled to the bedrock by an electric shovel or a light drilling apparatus (such as an auger, a small drill, a screw pile apparatus, etc.), and the height of the round pipe is equal to or greater than the depth of the shallow hole. Such shallow holes typically have an internal diameter of 150 mm or more (typically a larger diameter) than the borehole to allow deployment of larger volume seismometers, and the use of PVC pipe capping for shallow wells minimises installation costs. The bottom of the shallow hole is leveled and then fixed by cement, and then is compacted to be horizontal to form a stable layer, so that the seismograph can be conveniently installed, and then a PVC circular tube is inserted into the shallow hole until the PVC circular tube contacts the stable layer (the cement layer).
And then, the seismograph is stably pulled by a steel wire to be put into the well at the bottom of the processed shallow hole, and after the level and the direction are adjusted, dry sand is slowly poured into the well, so that the seismograph is completely covered. The sand is filled around the whole seismograph, so that the seismograph is firmly fixed in the shallow hole, and a good combination is formed between the circular tube and the ground. The installation device of the shallow hole direct-buried seismograph can effectively eliminate air convection around the seismograph, and more importantly, the installation device can effectively couple the seismograph with bedrock to obtain optimal ground motion observation data.
However, the method is easy to cause the following inconvenience in the actual installation process: 1. the cement-based stable layer cannot guarantee the level in the actual forming process, mainly because the stable layer needs time to solidify in the forming process, and the cement is fluid and is easily influenced by gravity in the solidifying process, so that the level cannot be guaranteed; 2. after the seismograph is placed on the stable layer, the sandy material is introduced, but in the actual pouring process, due to the fact that the pouring directions are consistent, the position of the seismograph is easy to change in the pouring process of the sandy material, or the horizontality of the seismograph is easy to change, and the detection result can be influenced.
