Should be with van Z K series of empty Note grouting anchor rod should be extensively with fei not often. It was working party, not always easy to keep credit note Pulp full full, often by engineering technical personnel should be Use in public, iron road, tunnel and water The water power engineering, cavern under open to dig A guard.Recent years, many side slope engineering Small type anchor fixation is gathering large tons Empty in the anchor rod, anchor pile from the generation section Save large amount of work time and work process Price. 价 。 |
We mentionedIn large quantity engineering practice in the table, to crack gap than the article hair) of surrounding rock mass, the traditional sand pulp through anchor rod without method
Slurry injection pressure force to crack filled gap, to change a good surrounding rock and can effectively adjust the rock soil body since the body strong degree and the stability can force the mesh.In the
Empty slurry injection anchor rod has by in large quantity to open to dig engineering under protection, sweeping solutions to the engineering of side wall and arch, and
A set of upward Angle of the arch of slurry injection pressure force of anchor rod and anchor solid protection.By the labor security, had made the engineering quality, and the quantity.
Structure. Z K of air injection slurry under the anchor rod is designed for each class to solid around the rock engineering and design, table surface by international often empty with consecutive wave shape of spiral grain
Heart of anchor rod as the main body, set and the match with a horse, but the most big limit by slurry injection when sand slurry filling full filling, dense solid.The sand slurry
Can be in high for 10 kg of pressure force

By using the anchor rod in the empty hole filling slurry infiltration in circumference Rock crack gap.To manage to protect effect. Z K in empty slurry injection anchor rod by hang hang anchor, anchor head Rod body, check pulp plug, such as cushion plate, screw the mother group Into, mother can pass through screw plus one forecast should be appointed force Shi work method Z K since by-step slurry injection anchor rod Work fast express, fuck as simple. 1. The drill hole hole cleaning.Use or normal drilling machines Car type drilling machine to drill out and make use of anchor rod gauge a The anchor hole and hole cleaning. |
