Compaction and vibration compaction device for filling soil around inclinometer pipe and construction method of compaction and vibration compaction device

Abstract

The invention discloses a tamping and vibrating device for filling soil around an inclinometer pipe and a construction method of the tamping and vibrating device, relates to the technical field of engineering monitoring, and can solve the problems of pipeline offset in the construction process and foundation settlement in the operation and maintenance stage caused by substandard pipeline backfill compactness. The guide mechanism is connected with the tamping vibration mechanism and is used for driving the tamping vibration mechanism to move in the inclinometer pipe; the tamping vibration mechanism comprises a front carrier, a rear carrier, vibrators and a variable-joint assembly, the end of the front carrier and the end of the rear carrier are each provided with one vibrator, and the variable-joint assembly is arranged between the two vibrators and used for positioning the tamping vibration mechanism in a pipeline of the inclinometer. According to the device, sandy soil filled outside the pipeline can be vibrated and tamped in the pipeline, the tamping vibration mechanism can move along the interior of the pipeline, all the positions outside the pipeline are tamped in sequence, it is guaranteed that the sandy soil is compactly filled, and the tamping quality is improved.

Description

technical field [0001] The invention relates to the technical field of engineering monitoring, in particular to a compacting and vibrating device for filling soil around an inclinometer pipe and a construction method thereof. Background technique [0002] After the inclinometer pipe is drilled, the diameter of the drilled hole is larger than the outer diameter of the inclinometer pipe. In order to solve the situation that there are gaps or cavities in the process of pipeline backfilling, it is necessary to fill the gap between the hole and the outer wall of the pipeline with fillers such as fine sand And wait for the consolidation to be stable before measuring. During this period, the filler needs to be replenished many times, which takes a long time. [0003] In order to facilitate the tamping operation, an attached vibrator is usually installed on the outside of both ends of the pipeline, and the tamping effect is achieved through the vibrator. The vibrator that adopts ou...

AI Technical Summary

Problems solved by technology

The vibrator that adopts outside attachment type setting has following shortcoming: 1, the vibrator that outside attachment type setting is not suitable for space narrow position; As a result, some parts of the pipeline are not filled in place, and there is a gap between the pipeline and the drill hole. The cavity generated by the insufficient filling of fine sand will destroy the structural strength of the fine sand filling, which will easily lead to displacement of the pipeline, resulting in later settlement deformation

[0004] The hydraulic ramming method can also be used for filling in the existing methods, but the slope operation has problems such as inconvenient transportation, long time consumption, and safety.

In the case of insufficient backfilling and tamping of the pipeline, it is easy to cause the deviation of the pipeline construction process or the shaking of the pipe joint during the operation and maintenance stage, which is not conducive to monitoring and construction
