Description

DEVICES FOR TAMPING LOOSE SOIL SURROUNDING
BOREHOLE
BACKGROUND OF THE INVENTION
I. Field of the Invention [0001]The invention relates to the field of landslide monitoring, and particularly to devices for tamping loose soil surrounding a borehole to realize the goal of the borehole reinforcement.

2. Description of Related Art [0002] Displacement is an important object of landslide monitoring, and particularly the deep horizontal displacement of landslides. As an important technique for monitoring the deep horizontal cumulative displacement of landslides, the inclinometer technology is the most recognized among the existing methods for its high accuracy and good reliability. When an inclinometer pipe is buried, measurement errors might occur due to the insufficient contact between the inclinometer pipe and soils around the pipe. The insufficient contact is caused by two reasons: 1) In the vertical direction of the sliding mass, the rebound amount of the soil at different depths along the radial direction of the borehole is different due to the change of strata; 2) Some sand layers collapse when the inclinometer pipe is buried.
Similar materials filled around the inclinometer pipe cannot fully fill the space between the inclinometer pipe and the borehole. When the sliding mass is deformed, inaccurate relative displacement is generated at each depth measurement point of the inclinometer pipe, which results in abnormal measurement results. Therefore, a method of tamping and strengthening the walls of a borehole before embedding the inclinometer pipe is proposed.

[0003] The existing reinforcement methods for underground drilling structures mainly include two types, one type is grouting reinforcement and the other type is mechanical method. Grouting reinforcement mainly achieves the purpose of drilling structures reinforcement by spraying cement slurry in the borehole to improve the strength of the soil on the side wall of the drilling structures. Chinese patents CN101603414B, CN104912515A elaborate on this. Such methods have limitations in their use as they alter the strength of the soil around the borehole and are not suitable for the monitoring methods through borehole. The mechanical method is a design protection device (European patent EP0726383B2), drill hole reinforcement (Chinese patent CN201218073Y), ring protection structure (US Patent US7416770B2), pneumatic compression method (Chinese patent CN205839724, CN101749005B, US patent US
2011/ 0086942 A 1 ), etc., to achieve local or integral reinforcement or protection of the borehole. At present, there is no mechanical reinforcement method for the design of the inclined drilling. Therefore, a device for tamping vertical geological borehole wall and reinforcing the borehole wall is needed to be proposed, which can solve the coordinate deformation problem of the inclinometer pipe and the slip mass and the reinforcement problem of the borehole wall at the same time, has important practical significance for engineering applications in the field of geological hazard monitoring and prevention.
