Izvest1 N ycipoiicTBa lining elements for laying in underground structures arch chamber wall naprimbr, mine type camera ispolzuyuschies for erecting tunnel lining monolitnop ,, comprising sektsiennuyu formwork with a hinge between a crestal soediiennymn and wall element and a movable portal and bolt mechanisms for gripping and displacement of protein elements established on the ground.

Such a device would allow the floor to be molded, disassembled and transsorted the entire section of the formwork, providing the possibility of mechanized paging of the section of the old part or the place of its removal to the place of the new installation. It can also be successfully applied for laying the lining elements into the arch and walls of the underground structure when replacing the arch: i wall formwork elements are appropriate for the arch and wall lining elements.

However, the known device does not allow for the possibility of laying the lining of the lining into the vault and the walls of the chamber, 1, it is different in height, and the arch does not have a zo.m. / chnost;

The aim of the invention is that in e.tc the improvement of the feasibility of laying lining elements in chambers having different heights.

To do this, in the proposed device, the guides are made outwardly and secured, on the arch, which are installed on the girder with the possibility of vertical movement, for example, by means of the T-block system.

FIG. 1 shows the device in the operating pollutions; in fig. 2 - the same: 5 transport position.

The device includes a portal /, consisting of a bolt 2 and two racks 3, supported on carts 4, having the ability to move along the rail 5; arch 6 with adjustable supports 7 and mechanisms 8 (pa.pri1mer, tal) D. for gripping and displacing the side chamber lining elements mounted on the rail -9, which have the ability to slide out with fixing clamps 10 along the roller supports 11, fixed on the clamp of the 12th arch 6.

The arch 6 is fixed on the rod 13, which is vertically mounted in the sleeve 14 of the crossbar 2. The rod 13 ends with a crosspiece 15 with eyelets 16, to which the lower blocks 17 of polyslasts 18 are fixed. The upper blocks 19 are fixed to the eyes 20 of crossbar 2. The corresponding threads 21 of the polisnasts 18 through the tap-off units 22 are connected to the hoist winch drum 23. Otvodnp: blocks 22 1 drum 23 mounted PA) 1 floor of the outer beams 24 of the portal /.

Laying of lining elements into the roof and walls of the chamber of an underground structure is produced as follows.

With a fully lowered roof 6, extended along Katkov supports 11 and fixed by fixers 10 in the extreme position of the guides 9 at the loading point of the device, the lower parts 25 of wall elements are suspended to mechanisms 8 (for example, tal m). Moving along the rails 5 the entire device, the lower parts 25 of the mounting elements in a suspended state are transported to the installation site and are installed in the design position.

Then, moving the entire device along the rails 5, returning it to the place of loading, install the roof element 26 on the driving gadfly 6, and to the mechanisms, mothers 8 hang the upper parts 27 of the wall elements. At that, mechanisms 8 with suspended upper parts 27 of wall elements are moved along guides 9 to the axis of the chamber so that the lower ends of the suspended upper parts 27 of the standing elements do not prevent the device from moving along the chamber (see Fig. 2).

3-atem, moving along the rails 5 the whole device with the roof element 26 and the upper parts 27 of the base elements, serves it to the place of installation. At the place of laying, the roof 6 is lifted upward by means of the cable-blocking system to the rod 13 to the up position and the gadfly element 26 is set to the design position. After that, moving along the rails 9 of the mechanism, we 8, with the upper parts of the 27 steel elements suspended from them, set the latter into the design position; prefixing the joints 28 between the lining elements, leaving the windows where the inciting 9 pass (see Fig. 1). Then

release the mechanisms 8, slide the camera axis in direction and fix the guides 10 with locks 10, perform the final sealing of the joints 28, lower the roof 6 into the lower position and feed the entire device

to the place of loading.

Next, the lining cycle is repeated.

Subject and title

A device for placing lining elements into the arch and walls of the chamber of an underground structure, including a movable portal with a bolt, arch with adjustable olors and gripping mechanisms and a pair of side elements mounted on rails, characterized in that, in order to provide the possibility of laying lining elements with chambers having different heights, guides made retractable and fastened to the arch, which is mounted on the girder with the possibility of vertical movement, which are the means of the ESR troso-block system.
