Audited Supplier Small pipe grouting is a measure of shallow buried tunnel support. In the weak and broken strata, it is easy to collapse the hole after drilling, and it is difficult to apply the leading bolt or the structure section is large, the small leading pipe support should be adopted. Leading small pipe support must be used with steel arch. When conditions permit, advance grouting reinforcement can also be carried out on the ground; When there is a guide tunnel, radial grouting reinforcement can be carried out around the tunnel in the guide tunnel.
2. The general measurement of small pipe grouting support is as follows: the diameter of steel pipe is 30-50mm, the length of steel pipe is 3-5m, the distance between grouting holes drilled for steel pipe is 100-150mm, and the distance between circular arrangement of steel pipe along the arch is 300-500mm. The circumferential insertion Angle of the steel pipe along the arch is 10° -15 °, and the small pipe is the force rod, so the two rows of small pipes should have a certain lap length in the longitudinal direction, and the lap length of the steel pipe along the longitudinal direction of the tunnel is generally not less than 1m.
Before the installation of the pipe, the working face should be closed tightly and firmly, and cleaned up, and the position of the drill can be measured before construction.
3. In order to ensure the stability of the working face and the safety of excavation, the installation position of the small catheter should be correct and the effective length should be sufficient, and the drilling Angle of the small catheter should be strictly controlled. C, used as a small conduit, has a grouting hole for grouting reinforcement to the soil, which is also conducive to improving the stiffness and strength of the small conduit itself.
4 Small pipe grouting should use cement slurry or cement mortar. The grout must be filled with cavities and surrounding voids, and the amount and pressure of grouting should be determined by test.
In order to ensure grouting quality and prevent leakage, sealing holes should be set at the tail of small conduits during tunnel excavation.
