Self-vibrating flow-jetting and grouting anchor rod integrated construction equipment and method

Abstract

The invention discloses self-vibrating flow-jetting and grouting anchor rod integrated construction equipment and method. The equipment is composed of a self-vibrating flow-jetting and grouting anchor rod, a high-pressure rotary slurry mixing device, a grouting device and a hydraulic driving device. The self-vibrating flow-jetting and grouting anchor rod is a hollow rod body with a screw-edge stirring piece, and the front end of the anchor rod is provided with a vibration generator which is connected with a drill bit; the upper portion of the high-pressure rotary slurry mixing device is provided with a feed hole, the bottom of the high-pressure rotary slurry mixing device is provided with a rotary supporting leg which can freely lift and rotate, the front portion of the high-pressure rotary slurry mixing device is provided with a flow-jetting spray pipe, an inner cavity is provided with a rotating shaft, the front end of the rotating shaft is provided with a connection plug, the connection plug is cooperated and connected with a connection inserted groove of the self-vibrating flow-jetting and grouting anchor rod, the rear end of the rotating shaft is provided with a bearing, and the two ends of the rotating shaft are provided with high-pressure sealing boxes. The grouting device adjusts the grouting amount and the grouting pressure at any time, and the hydraulic driving device provides rotating power. The equipment and the method is widely used in support and reinforcement engineering in mines, transportation, water conservancy and other engineering fields, the application prospect is broad and the economic benefit is remarkable.

Description

technical field [0001] The invention relates to bolts used in the fields of mining, transportation, water conservancy and engineering. Background technique [0002] In the fields of mining engineering, geotechnical engineering, tunnel engineering, etc., in order to prevent the deformation or instability of the formation and surrounding rock and endanger the safety of the project, it is necessary to support and strengthen the surrounding rock of the formation, and the bolt support reinforcement technology is the most widely used a support technology. Bolt support can not only give full play to the stability of the rock and soil itself, but also has little disturbance to the original rock, fast construction speed, safe and reliable, and economical and effective. Therefore, it is used in mine support, tunnel support, slope support, large-scale It is widely used in the support of underground chambers, as well as anti-floating and anti-overturning projects of various buildings. ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to overcome the deficiencies of existing grouting bolts, provide a self-vibrating jet grouting bolt integrated construction equipment, and solve the problems of high rock fragmentation, crack development, and short self-stabilization time of surrounding rock in underground engineering. protection problems, as well as the low drilling efficiency, long construction period and complicated procedures caused by the hard rock at the bottom of the hole, it can be used as both permanent support and temporary support
