Description

Lowering reinforced concrete fastenings for mines, assembled by “3 finished rings, are already known.

In the proposed lowering reinforced concrete fastening, reinforced concrete rings are provided with double metal flanges: the cavities of which are filled with a solution or the like after connecting the flanges of adjacent rings in order to form my own waterproofing and fastening. To fill all the cavities of the flanges with a solution on top of the cavity, the double flanges communicate with each other by longitudinal channels in the walls of reinforced concrete rings. The flanges are formed from channel iron rings and are attached to the longitudinal reinforcement of reinforced concrete fastening rings.

In the schematic drawing of FIG. 1 shows a lowering reinforced concrete fastening for mines in a plan view, FIG. 2 - in the longitudinal and FIG. 3 - in a section along a - and FIG. one.

The proposed mount consists of individual rings 1 1.5-2 m high.

Reinforced concrete rings are equipped with double flanges 2 of .well LP. The fastening of the rings between themselves is carried out by bolts 3. Waterproofing at the points of joint of the flanges is achieved by means of waterproofing gaskets 4.

After the completion of the drilling of the mine, the barrel remains filled with clay mortar. Therefore, the assembly and lowering of the mount into the mine is made afloat. For this, the first ring of fastening is known to have a concrete bottom 5.

The skeleton of each ring is fastened, and consists of external and internal channel rings 6, connected by a reinforcement 7.

To create a solid reinforced concrete fastening to the entire depth of the mine, the space 8 between the upper and lower channels is filled with cement mortar. For this purpose, longitudinal channels 9 are provided.

After each ring is fastened from the top through these channels, the cement mortar is filled with a pressure sufficient to fill the space between the upper and lower channels of the fixture.

Before filling all openings close with traffic jams except

one, in K.oT (j.poe plant t is a cement hose pump and it is pumped out. To ensure that the cement mortar is filled with all of its annular space, the hose transfers the opposite hole n and leads through it, etc. all space will not be filled.

The result is a solid, simple to manufacture directly on the shaft, prefabricated reinforced concrete mount, mounted: on the surface and dyush, its water resistance is sufficient to submerge it.
