Embodiment Construction
[0046] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0047] An embodiment of the present invention provides a temporary support device for shaft excavation, such as figure 1 , figure 2 As shown, the support equipment includes:
[0048] A ring beam 1 with a closed frame structure, and a retaining beam 2 fixed on the outside of the ring beam 1; the length direction of the retaining beam 2 is arranged along the axial direction of the ring beam 1;
[0049] The ring beam 1 includes at least two end-to-end adjacent sub-beams 11 and an expansion-shrinkage assembly 12 connecting the ends of the adjacent sub-beams 11;
[0050] When the expansion-shrinking assembly 12 is extended, the distance between the ends of the adjacent sub-beams 11 increases, and the outer side of the retaining beam 2 ab...

The invention relates to the technical field of shaft sinking construction and discloses temporary supporting equipment for shaft sinking. The supporting equipment comprises a ring beam and side protecting beams fixed to the outer side of the ring beam, and the length direction of the side protecting beams is set along the axis of the ring beam. The ring beam comprises at least two end-to-end adjacent sub-beams and expansion-contraction components connected with ends of the adjacent sub-beams. When the expansion-contraction components extend, the distance between ends of the adjacent sub-beams is increased, and the outer sides of the side protecting beams are abutted against the side wall of a shaft; when the expansion-contraction components are shortened, the distance between ends of the adjacent sub-beams is decreased, and the outer sides of the side protecting beams are separated from the side wall of the shaft. By extension of the expansion-contraction components, the side protecting beams is closely abutted against the inner wall of the shaft to support the same, so that workers can continue cutting operation above or below the supporting equipment, supporting of the side wall of the shaft temporarily supported by the supporting equipment is realized, and project progress is accelerated due to synchronization of cutting and supporting.
Description
technical field [0001] The invention relates to the technical field of shaft excavation construction, in particular to a temporary support device for shaft excavation. Background technique [0002] In the construction of underground projects such as mine roadways and traffic tunnels, in order to ensure the smooth progress of construction, it is necessary to dig shafts for transporting materials and ventilation. The upper end of the shaft is connected to the ground, and the lower end of the shaft is connected to the roadway or tunnel. In shaft construction, shaft excavation is carried out through excavation operations, and the excavated shaft side walls are permanently supported through support operations. Among them, the support operation mainly includes: driving anchor rods into the side wall of the excavated shaft, fixing the metal mesh on the anchor rod, and then spraying concrete on the metal mesh, and forming permanent support for the side wall of the shaft after the c...
