Description

The invention relates to the field engineering, tunneling, in particular to yctpoi. Vam for sinking underground vans, |, - There are known devices for sinking under excavations, including a transverse frame, equipped with double-acting power glasses and supporting it; team (installed from the watermark of autonomous perekascheni elemsitspaishpuntin) outer shell. t Such devices allow the i 5 temporary fastening of the contour of the developed ..Kf as it penetrates, mixing the elements of the outer shell of the outer casing with forceful double-acting dramas of double action, mounted on a 11frame frame, can not be independently mixed forward. following, aa penetration, since the transverse frame is only a support frame. This complicates the entire i technological cycle of penetration, as the Macro needs to be moved forward with the use of pre-singing mechanisms. (The purpose of the invention is to simplify the completion of the work.);.:: -:.;:.,:.,.;

This is compounded by the fact that it is transverse | frame, vpo; n, the device is a composite of the support and, the tunnel frame, between which; Viewed by the power force of the double action, with the frame being fitted with stop bolts, fitted. ; mi with the ability to move in paaa, j imbricated in elements shtguitinvh, kwzh, of which are made along the length of the composition-

4 double action. The frame 2 and the tunnel frame 3 are supported by the elements of ajnyiiTHiibi 5, which form a tight shell of the YP in the frame. Each of the episodes ishuit

5 is made along the length of the composite and has a front section 6 with a pointed 7 and. One thicker section 8 is smaller than j in front of section 6. Section 6 and in Lemite-Ilpuntin 5 are connected together by means of a hinged bolt 9i

Roaming Roma 3 is equipped with resistant boptrm .10, installed with the possibility of placement in the grooves C, formed in x-hapuntins 5. 5. The bolt 1.0 L1szh "t was made by a non-uniform and has a tooth 12 on the KONIR ynopmiift, Device LP 1) :) The mine workings are working as follows.

By means of power and hydrophores 4 npo-j, the ppmu 3 place: go to it, they will rewind forward to the supporting ppme 2. At the same time, thanks to the aggravation of the movement, elm1ttiujnyrirHH i 5 Frames 3. It is necessary for this implementation of the force of the reaction of the sclots to the cylinders 4 nepeariiorca through the supports (row 2 of the moving elements of the spuditstlm 5 are replicated by the forces of friction arising between the fixed element-bogs 5

Then the cycle of work is repeated until all the elements of the shuntina 5 are moved forward by the value of the year of the power cylinders 4.

After that, the support frame 2 is moved forward by the stroke of the power 1H linlf 4, the quality of the quality | into the supports of the tunnel frame 3, for which the flap 19 is inserted in the hook with a tongue 2 I elemegg-chipuntiyy 5.

Inside the space bounded by the rear section 8 of the sheet piling 5, an external metal lining 22 can be mounted, allowing the Yusha to perform a device 110 in the lateral lining 23, for example concrete, some paccTojfiujH from the bottomhole zone. For the operation of the inner lining 23, formwork 24 is used, the torin of which closes the flade-K 25.
