Problems solved by technology

[0009] The object of the present invention is to provide a device and method for radially implanting subsidence signal marks in boreholes in soft soil formations, which can use the extremely limited inner space of the wall sleeve to place each subsidence signal mark through the corresponding reserved hole for planting marks Implanted into the ground, the settlement mark can move freely and consistently with the surrounding soil, which solves the problem of difficulty in setting the settlement mark in layers of deep soil

Abstract

The invention provides a soft soil stratum drilling inner sedimentation signal beacon radial planting device and method. A beacon planting control box, a traction line and a beacon planting device areadopted and included. The beacon planting device is located in a wall protection sleeve. The wall protection sleeve is placed in a stratum in a following manner in the drilling, digging and cutting process, the beacon planting control box drives and draws the traction line to drive the beacon planting device to move up and down in the wall protection sleeve, the beacon planting device can be aligned with various beacon planting reserved hole positions of the wall protection sleeve, a series of beacon planting reserved holes are set in a sleeve body of the wall protection sleeve according to the vertical layering monitoring position requirement, and temporary seal holes are adopted in the beacon planting reserved holes. Through the beacon planting device, various sedimentation beacons canbe planted in the stratum through the corresponding beacon planting reserved holes by utilization of the limited sleeve interior space of the wall protection sleeve, the sedimentation beacons are independently arranged in the stratum and can freely and consistently move along with a surrounding soil body, and the problem about difficult layering arrangement of the sedimentation beacons in a deep-layer soil body is solved.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering monitoring, and in particular relates to a radial implantation device and method for a subsidence signal mark in a borehole of a soft ground layer. Background technique [0002] During the construction of rock and earth underground engineering, in order to ensure the safety of the project itself and effectively control the impact on the surrounding environment, it is necessary to grasp the deformation and trend of the surrounding stratum medium in time. Through settlement monitoring, the important data index of stratum settlement can be collected in real time. As the depth of underground space development continues to increase, the use of relatively simple surface settlement monitoring can no longer directly reflect the soil deformation around the construction work area. The implementation of deep soil settlement monitoring can provide more effective environmental impact quantitati...
