Embodiment Construction

[0036] Such as figure 1 As shown, a sensor embedding device includes a guide tube 1 and a compaction mechanism arranged in a drilling pit. A lifting drive mechanism is provided on the top of the drilling pit. The lifting drive mechanism includes a bracket 2 and a first fixed pulley arranged on the bracket 2. 3. One end of the first steel wire rope 4 is connected with the guide sheath 1, and the other end bypasses the first fixed pulley 3. The sensor 5 is arranged in the guide sheath 1. A compaction mechanism is arranged outside the guide sheath 1, and the top of the compaction mechanism There is a second steel wire rope 6, the end of the second steel wire rope 6 goes around the second fixed pulley 7, and the second fixed pulley 7 is arranged on the support 2.

[0037] By setting the guide tube 1 to make the sensor enter the drilling pit in a vertical state, the sensor can be protected to prevent the sensor from being damaged when it is buried. The backfill is compacted by setting...

Abstract

The invention provides a sensor embedding device and an embedding method thereof. A guiding protection barrel and a compaction mechanism are included and arranged in a drill pit. The top of the drillpit is provided with a lifting drive mechanism. The lifting drive mechanism comprises a support and first fixed pulleys arranged on the support. One end of a first steel wire rope is connected with the guiding protection barrel, and the other end of the first steel wire rope bypasses the first fixed pulleys. Sensors are arranged in the guiding protection barrel. The compaction mechanism is arranged on the outer side of the guiding protection barrel, a second steel wire rope is arranged on the top of the compaction mechanism, the end portion of the second steel wire rope bypasses second fixed pulleys, and the second fixed pulleys are arranged on the support. Through the device, it is guaranteed that the sensors are located in the same vertical plane, and the sensor embedding soil compactiondegree is improved.

Description

Technical field [0001] The invention relates to the field of soil sensor burying facilities, in particular to a sensor burying device and a burying method. Background technique [0002] In the field of geotechnical engineering technology, underground engineering construction or scientific research such as dams and slopes often need to monitor various physical and mechanical parameters within the soil and conduct multi-physical coupling analysis. Therefore, acquiring important physical quantities in rock and soil is an important prerequisite for studying geotechnical problems. [0003] The method of burying the sensor in the soil is usually the drilling method. Use the drill rod of the drilling rig to press into the designated design elevation, bury the sensor, and manually backfill and compact. As far as this scheme is concerned, the measured data are not necessarily in the same vertical plane and are not comparable; since the clay is always in block form, the soil is generally p...
