Blocks of walls of a cellar (stenovye blocks) or a technical underground start to mount after check of position of the laid base plates and the waterproofing device. Usually as isolation spread a layer of a solution in the thickness 20... 30мм on the cleared surface of the bases. It simultaneously serves as a levelling layer.
Stenovye mark blocks letters and in figures. For example, ФС4-24 or ФС4-4 where letters FS designate a block kind - base stenovoj; the first figure - nominal width, and the subsequent - length (all in decimeters). If the marking of axes is not made on the bases at drawing up of the executive scheme before installation stenovyh blocks mark the basic and intersection axes of a building and border of walls which fix on the bases corresponding risks. The marking is carried out by means of geodetic devices and wire axes by old clothes the same receptions, as at a marking of the bases. Further on an assembly diagramme mark on the bases position stenovyh blocks of the first (from the bases) a number, marking places of vertical seams.
Workplace Preparation consists that zvenevoj and the assembler bring to a place of installation a box with tools. They clear a surface of the bases of dust and establish a box with a solution on distance 2000... 2500мм from a wall so that it was possible, without rearranging it on a new place, to mount 3... 4 blocks.
Installation begin with installation majachnyh blocks on distance 20... 30м from each other in corners and places of crossing of walls. The block lifted for two loops, the crane submit to an installation site, develop in design position and lower on bed from a solution. Correctness of installation on axes majachnyh blocks check on axial risks, and on height - on vizirke. If position of the block after check has appeared wrong, the block again lift, clear the bottom side of a solution and restore rastvornuju bed, adding a solution at that party of bed in which the block has bent.
By preparation of bed a surface of blocks clear of dust and moisten with water, a solution submit and level a shovel. Better quality of bed turns out, when a solution level rejkoj on a framework, horizontal position of bed in this case is provided and its thickness is fixed.
After installation majachnyh blocks pull at level of their top and on distance 2... 3мм from a lateral side a cord-prichalku also fix it skobami 3 (fig. 132). Further ordinary blocks establish on a solution on a cord-prichalke. Lowering the block on a place, it direct, holding for slings or the top lateral edge. It is impossible to keep a hand for a block end face, near to earlier established block, - it is possible to press a hand mounted elements.

And - zadelka a vertical seam, - rihtovka the block at installation;
1 - a box with a solution, 2 - prichalka, 3 - skoba for fastening prichalki, 4 - a base plate, 5 - rastvornaja bed
Position of ordinary blocks supervise on a cord-prichalke 2, a plumb, vising on earlier established blocks and on razmetochnym to risks on the bases. If the block is established is inexact, its position correct assembly lomami, moving to the necessary direction.
Blocks of external walls of cellars level on a plane turned towards a cellar, internal walls - on one of planes. Having convinced by that the block is established correctly, assemblers rasstropovyvajut it, kelmoj cut off surpluses of the solution which has acted from a horizontal seam, and stack it in a well of a joint of blocks. A shovel add in a joint missing quantity of a solution and condense it.
For moving of blocks on rastvornoj beds use three basic methods: a paw of a breakage from itself, a paw aside and a paw on itself. In reception by a paw from itself (fig. 133, the delayed end of a breakage get under the block and wring out a breakage from itself on the block which thus rises a little and, sliding off a paw, moves ahead. In reception by a paw aside (fig. 133,) the delayed end of a breakage get under the block at an acute angle to its obverse side. Pressing then a breakage and turning it on a paw heel aside, raise the block and move it. The direction of movement of a breakage and the block is shown in drawing by arrows. In reception by a paw on itself (fig. 133,) the delayed end of a breakage get under the block and, pressing the breakage end, raise and move the block on itself. At the big thickness of a seam instead of reception by a paw from itself apply reception by the sharp end from itself. Movements at performance of these receptions the identical.

Following numbers of blocks mount in the same sequence, doing a marking of an apportion of blocks on underlaying to a number. First two numbers of blocks establish from the laid base plates, the subsequent - with inventory podmostej.
To Mark of a solution on which blocks should be mounted, specify in the project.
