Zusammenfassung: | The invention relates to a hydraulic retaining and protecting template for preventing a vertical shaft from generating water percolation. The hydraulic retaining and protecting template comprises two retaining and protecting wings which are symmetrically arranged, an anchor rod and a radial hydraulic lifting jack, wherein the two retaining and protecting wings are connected through the radial hydraulic lifting jack; the radial hydraulic lifting jack is connected on fixed supporting bases of the two retaining and protecting wings; the radial hydraulic lifting jack can be used for fixing the retaining and protecting wings onto a well wall. Each retaining and protecting wing consists of at least two segmented retaining and protecting templates, a transverse hydraulic lifting jack, an elastic water-plugging rubber layer and a fixed supporting base. The hydraulic retaining and protecting template can be used for plugging relatively large well-shaft water rushing, achieving a water plugging effect within a relatively short time, and avoiding possibility that a laneway is scrapped due to water percolation to a relatively great extent. The technology is obviously superior to an existing water plugging mode, the using process is simple, and the water plugging effect is timely and effective. |
