Technical Field

[0001] The utility model relates to the technical field of grouting, in particular to a wind pressure type drilling grouting equipment. Background Art

[0002] Tunnel engineering is affected by different strata and is prone to landslides, sand surges and other adverse engineering hazards. Measures must be taken in advance to reinforce the strata in order to ensure construction safety. Tunnel full-section grouting reinforcement technology includes small-duct grouting, sleeve valve pipe grouting, and other methods.

[0003] Among them, small-tube grouting and sleeve-valve tube grouting need to be inserted into the steel pipe and sealed after the drilling is completed. The sealing effect is generally difficult to meet the actual grouting needs in a short period of time, resulting in unsatisfactory grouting effect. Due to the limitations of construction technical conditions, the grouting length of small-tube grouting and sleeve-valve tube grouting is generally not more than 10m at a time, and the duration is relatively long.

[0004] Therefore, under the premise of ensuring construction safety, how to minimize the adverse effects that may occur due to different underground geology in the shortest time, speed up the construction progress, improve the grouting construction efficiency, and improve economic benefits are the problems we need to solve.
