Soil pressure sensor mounting, loading and testing device, and operating method thereof

Abstract

The invention discloses a soil pressure sensor mounting, loading and testing device, and an operating method thereof. A punching mechanism and an embedding mechanism are not required to excavate a tunnel for embedding a sensor in advance, and are only required to downwards drill a hole for placing the soil pressure sensor along a certain angle; the excavated tunnel is prevented from influencing a boundary effect of a testing point for embedding the soil pressure sensor; the disturbance and the damage to a structural state of in-situ soil can be reduced to the greatest extent; the labor intensity of embedding the soil pressure sensor is reduced; a loading and testing mechanism is controlled by a hydraulic drive which is stable in loading speed and accurate in control; and the transmission condition of stress in a soil body is reflected by a loading load and loading stress measured by the soil pressure sensor embedded in the soil body, so that a compaction and stress process of farmland soil can be reflected more accurately. The soil pressure sensor mounting, loading and testing device is simple in structure, low in cost, convenient to use and accurate in measurement, is widely applicable to testing the compaction condition of the farmland soil, and is suitable for popularization and using.

Description

technical field [0001] The invention relates to the technical field of farmland soil monitoring, in particular to an earth pressure sensor installation loading test device for monitoring the compaction process of farmland soil and an operation method thereof. Background technique [0002] The compaction of farmland soil by field work tools reduces land productivity, and monitoring the compaction process of various field work tools to soil is the basic work to effectively avoid excessive soil compaction. Using soil pressure sensors to monitor the soil compaction process is an efficient method in the field soil compaction test method, but the current monitoring process is cumbersome to operate, and there is no complete and standardized operation method. The current method first needs to excavate a tunnel at the site to be measured, then drill horizontal holes at different depths on the side wall of the tunnel, and finally install the earth pressure sensor in the horizontal ho...

Problems solved by technology

[0003] The purpose of the present invention is to provide a novel soil pressure sensor installation and loading test device for field soil compaction testing in view of the lack of suitable equipment, time-consuming and labor-intensive testing process, and the lack of standardized operation methods in the current soil pressure sensor testing process of farmland soil compaction and how it works
