The common use of cement grouting and technical details

Cementation filling cracks or gap in soil and rock, and infiltrate the coarse granular soil to form the cementing quality. Hayward Baker's low headroom compact rig, minimize the disturbance to the normal facilities operation. Common use 1, 2, set obstacles for groundwater flow support mining support base 3, 4, stability, and strengthen the granular soil technical details 1, cement grouting, also known as the slurry or liquid grouting, grouting filling pore of granular soil or rock/soil voids, fluid particles of grouting. Must be appropriate matching grout size and gap size, so that the slurry infiltration. According to the specific situation, Portland cement or subtle slurry at strategic locations by stand-up or multi-port pipe injection under pressure. The grouting material has increased strength, stiffness and lower permeability. 2, cement grouting for alternative methods ( Removed and replaced or pile driving, for instance) Support of the application of economic advantage, and can be difficult to enter and under the condition of limited space. Due to the effectiveness of cement grouting to the connection structure, so the technology is easy to adapt to the existing basis, and often can not interrupt normal operation under the condition of complete facilities. 3, all can be real-time monitoring in the process of cement grouting parameters. The operator can adjust the parameters according to the real-time acquisition data of drilling and grouting ( Mixed type, for example, the velocity, pressure and volume limit) , at the same time the structure of the monitoring near the ground or any mobile or deflection. Data collected during the drilling and grouting record in the generated grouting report server, and describes a visual representation of work completed CAD drawings. The use of this advanced monitoring system can improve the accuracy of the cement grout, efficiency and quality control.
