The technological card was developed for the installation of precast concrete foundations of a glass type F 21.9-3, f 15.9-2, F 12.9-2, F 18.9-3.
The work of the work under consideration includes: setting the foundations of a glass type.
Adopted in the map The direction of installation of foundations, breakdowns on the captures and the movement of the crane are shown in the graphic part of the project.
4.5.2 Work Performance Technology
Prior to the start of construction and assembly (including preparatory) works at the facility, the general contractor is obliged to obtain permission from the Customer to carry out installation work. The basis for the start of the work is the act of intermediate acceptance of earthworks.
Prior to the start of installation of foundations, all preparatory work must be fully fulfilled, including:
Construction of temporary roads and entrances;
Separated the pit under the foundations;
The centering axes of the building are determined and secured;
Reperen are installed;
Selected constructions that have passed input control;
The required designs are imported and decomposed in the crane area;
Planned and prepared platforms for storage of prefabricated structures;
Delivered to the installation zone the necessary mounting agents, fixtures and tools.
Acceptance of an object for installation should be carried out by employees of the assembly organization on the act.
The warehousing zones are separated by cross-cutting passages with a width of at least 1 m every two stacks in the longitudinal direction and in 25 m in the transverse one. For the passage to the ends of the products between the stacks, the gaps are arranged, equal to 0.7 m.
Before mounting blocks of foundations, you must perform the following work:
Smash their installation places;
Apply in four faces at the level of the upper plane foundations of the risks of the installation axes in accordance with the project;
Apply the risks of installation longitudinal axes on lateral faces at the bottom level of the foundation block.
To break down the installation places of the foundations around the perimeter of the building or only at its corners, it is set to pick up, stretch the wire indicating the position of the axes, and with the help of the plugs, they carry the points of their intersection to the bottom of the pit, where they are fixed by pegs clogged into the ground.
Figure 4.4 - Geodesic breakdown of installation sites foundations

From the points measure the design position of the outer face of blocks. Additional and intermediate axes are placed with a metal tape measure.
Figure 4.5 - Breakdown of Foundation Blocks
On the foundations of the glass type, they define the middle of the side faces of the glass and apply axial risks on the upper face. Risks are applied with a pencil or marker. When lowering the foundation block, it is controlled by risks.
The design position of the base marks is installed using a level. So that the blocks of foundations do not hide from the sandy pillow, the width of it is made by 200-300 mm more soles of the soles of foundations.
The base prepared for the installation of the foundation should be made on the act of examining hidden work.
The foundation blocks are installed on the sand layer aligned to the project mark immediately into the design position to avoid impaired surface layer of the base. Installing blocks of foundations on water-covered or snow is not allowed. Bands of foundations and reference surfaces must be protected from contamination.
Installation technology. Sets the foundation unit on the prepared base of the link of the installers in the composition of three people. The installers of the 4th and 3rd discharges, being in the pit, purify and level the base under the foundation. At this time, the installer of the 2nd category prepares the foundation for the laying, checks the size of the glass and the mounting screens, and if necessary, replaces them with scrap or hammer. Then the 3rd discharge assembly, fixing the four-track sling on the block, moves to a safe distance, supplies a crane machine to a preliminary lifting of the block by 0.2-0.3 m above the ground. After making sure the reliability of the sling, serves as a crane driver to the lifting. The raised block inspects and cleans (its lower plane) from the nagwed soil. Then the craneker moves the block to the place of its installation. At an altitude of 0.2-0.3 m above the base, two other workers take the block, centen it at risks on the side of the side and by pegs on the base, and then smoothly lowered into place. With stretched slaps, installers rhytize it with lomits, combining risks on a block with benchmarks on the base. Accurately installing the block of the link gives the signal to weaken the slings, after which they are removed. The crane moves around the middle of the span of the building and from one parking sets several elements.
The position of the foundation unit in height is seorating with a level, controlling the bottom of the glass. The position of the block in the plan is checked with unauthorized lines by combining rice (installation and centering axes) in two mutually perpendicular axes, a small deviation is eliminated by moving the unit by mounting lomik. At the end of the installation of the foundation blocks, they carry out geodesic surveys of their position - altitudinal and in terms of. According to the results, the shooting is the executive scheme, which indicates the possible offset of the blocks.

1 - mounted blocks of foundations, 2 - Mounting scrap, 3 - mortar shovel, 4 - Mounted block, 5 - drawer with hand tool, 6 - Wooden rail.
The preparation of the block to installation and its feed is doing a rigger. It rages the block, checks the correctness of the hook, clears from the dirt and the influx of concrete, and making sure that the unit is ready for installation, sends it to the installation site.
The installers are preparing a block installation location: Using wooden stakes as a landmark, pre-clogged on the design mark of the base of the block, shovels align the base. Then the installers receive a block at an altitude of 200 ... 300 mm from the surface of the base, orient it in the right direction and allow the crane to be resolved to the prepared bed.
In the correctness of the installation, you make sure using axial wire, stretched on the pickup (this wire fixes the edge line of the block). Using a plumb, check whether the position of the mounted block is the project. When deviating, the block is rich using the assembly scrap.
Allowable deviations, mm
Disassemble the unit installers if necessary. They will throw the block, after its lift inspect the quality of the lines, clean the block from sand and soil, then allow the block to move to the storage area, where it takes the installer, places on the lining and removes the slings.

2. A worker performing installation work, a senior in the link and a worker, performing installation works withdraw hooks from the mounting loop of the block.
When preparing the basis it is important to work out the process of self-control. A worker performing installation work, the senior in the link periodically applies the rail to the upper end of the stakes of the stakes or the risks applied to them. The bottom of the rails fixes the level of the sand base, the quality of which is determined by the deviation from the horizontal. Since the rake occupies a horizontal position, it is necessary to measure the gap between the lower rear edge and the base surface at several points. These points must determine the students by challenge them at first visually.
If the gap between the lower edge of the applied rail and the base exceeds 5 mm or the rack length will be more than three deviations exceeding 3 mm, the base is unsuitable for installation of structures. The accumulation of a certain amount of deviations leads to a decrease in the quality of work. If inaccuracies are less than the norm, then work is considered satisfactory. This manifests itself the law of transition of quantity in quality.
Limit deviations:
From the combination of the installation orientation of the blocks of walls with the risks of the center axes - not more than 12 mm;
From the vertical of the top of the planes of wall blocks - 12 mm.
The solution march must match the project.
The mobility of the solution for the device bed must be 5-7 cm.
Installation of wall blocks should be performed with ligation.
Not allowed:
The use of the solution, the process of setting which has already begun, as well as the restoration of its plasticity by adding water;
Contamination of support surfaces.

Control of the accuracy of the device of precast tape foundations
Before starting construction work on foundation blocks, risks that determine the axis should be applied. In the presence of rice products, it is necessary to clarify their position. With proper geometric form of the block for the longitudinal and transverse axis, they take lines connecting two points of intersection of the diagonals of the side walls (Fig. 15).
Fig.15. Axis and risks of the block:
1 - longitudinal axis; 2 - transverse axis; 3 - metal plates; 4 - Risks
The axes are denoted on the edges as traces of crossing the planes spent through the transverse and longitudinal axes perpendicular to the upper face. At the same time, not all shown in Fig. 15 risks, but those that are needed to install the block are applied.
In the planned position, the blocks are installed using mechanical center, if the method of the sheer line is used, or by theodolitis, if the method of the vertical plane is used.
To install and verify the foundation blocks in height, you must have two additional repex on the bottom of the bottom with the levels of the foundation of the foundation.
The sequence of control measurements in the course of the device of prefabricated base foundations may be like this:
1) pour the leveling layer, for example, from sand, a thickness of about 10 cm and a 20 cm wide more than the pillow size (Fig.16).
2) Locked with studs or stakes the position of angular and lighthouse blocks at the bottom of the pit.
3) installed with the outer side of the studs or stakes on the sandy pillow frame or boards with labels of block axes and impose their planned position.
4) Determine the altitude position of the frames or boards on the level and install them on the project mark.
5) tamper and align the sand pillow to the frame level or boards.
6) Install on the prepared base blocks so that their basic tags coincide with the marks of the frames or boards.
7) Check the position of angular and light-air blocks on the level (in this case, the countdown on the railway standing on the block must be less than the rail point in the reference point on the thickness of the block).
8) produce control planning measurements of the parties and diagonals in sections, limited by corner and early blocks, and compare them with design dimensions;
9) Tensioning at the level of the upper outer edge of the angular and light-air blocks or between the loaf blocks the part and it controls the installation of other blocks, filling the gap.
Fig.16. Monitoring the accuracy of the installation of the pillow by center marks:
a - general view; b - section
When the foundation device, you need to break holes for skipping underground communications. The planned position of the inputs is determined by a precursor from the main axes, and the altitude - from the references. The breakdown of inputs should be carried out before assembling blocks.
