Abstract

The invention discloses a self-vibrating jet grouting bolt integrated construction equipment and method, which is composed of a self-vibrating jet grouting bolt, a high-pressure rotary grout mixer, a grouting device, and a hydraulic drive device. The self-vibrating jet grouting anchor rod is a hollow rod body with a helicoidal stirring plate, a self-vibration generator is arranged at the front end of the anchor rod, and the self-vibration generator is connected to a drill bit. The upper part of the high-pressure rotary mixer is provided with a feed inlet, the bottom is provided with a rotating leg that can be lifted and rotated freely, the front part is provided with a jet nozzle, the inner cavity is provided with a rotating shaft, and the front end of the rotating shaft is provided with a connecting plug. It is matched and connected with the self-vibrating jet grouting bolt connection slot, the rear end is provided with bearings, and both ends are provided with high-pressure sealing boxes. The grouting device adjusts the grouting volume and grouting pressure at any time, and the hydraulic drive device provides rotation power. The invention will be widely used in support and reinforcement projects in engineering fields such as mines, transportation, water conservancy and the like, and has broad application prospects and remarkable economic benefits.

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. ...
