Description

one

The invention relates to construction and can be applied when sinking wells.

The purpose of the invention is to increase productivity when lowering the sill bolts by simplifying the process of moving the jacks along guide posts.

cut along one of the guide posts; figure 2 is the same, the view in the plan; on fig.Z - jacking device walking type; figure 4 - section aa in fig.Z.

A device for pushing into the ground the roof support 1 contains a monolithic reinforced concrete anchor with respect to C 2, along the perimeter of the inner surface of which metal racks 3 are arranged, reinforced in an anchor across CE 2 with anchors 4 and reinforced in the upper part with struts 5. Guides 3 They are equipped with a walking-type jacking device consisting of two parallel power cylinders 6 mounted on a guide post 3 connected at their ends by flanges 7, the lower one of which is equipped with a rigidly fixed console 8. The jacking device is moved along guide posts 3 with the help of two sets of toothed cone-shaped cheeks 9 alternately clamping guide post 3. The return stroke is performed under the action of hydraulic pressure or by means of steel springs 10 with which the power cylinders 6 are fitted.

The device is mounted in the following sequence. First, build 10

monolithic reinforced concrete anchors are pressed at from 2 with simultaneous installation; anchors 4 and struts 5 for subsequent fastening of metal guide posts 3 into them. Then, power cylinders 6, equipped with a cantilever 8 fixed on the bottom flange 7, are mounted on guide posts 3.

Crushing into the ground underlay support the proposed device sapl-. are as follows. Inside the monolithic reinforced concrete anchor belt 3, the next lowering lining ring 1 is mounted when the power cylinders 6 are raised to the extreme position (top). By turning on the power cylinders, the console 8 is pushed to the top of the lowered support ring and with the further movement of the power cylinders 6 by two sets of toothed cone-shaped cheeks 9, alternately clamping the guide post 3, pushing the ring 1 into the ground while simultaneously developing the soil inside the ring 1.

After the next ring is pressed down, the descending lining 1 of the power cylinders 6 is retracted (up), which is provided by the steel spring 10 of each cylinder 6, and the cycle of mounting and crushing is repeated.

After completion of the crushing into the ground support, the metal pillars 3, the power cylinders 6 with the consoles 8, the struts 5 and the anchor 4 are dismounted for reuse at another construction site.
