- cleaning of soil from the pile mouth and loading of drilled soil into the dump truck;
- installation of reinforcement frame in the well and concreting of BNS;
- processes related to quality check of works.
Characteristics of the working conditions.
The works shall be performed in accordance with the working drawings and SP 45.13330.2017, SP 501022003, SNiP 12032001, SNiP 12042002.
This JI provides for work performance in summer time in two shifts.
4.1.2 Organization and technology of the construction process.
Instructions for preparation of construction site and requirements for readiness of previous works.
All works of the preparatory period, including fencing of the territory of the construction site, arrangement of temporary office premises and provision of sanitary and household needs of the workers, shall be performed at the construction site prior to the start of BNS construction works.
During construction, the pit should be opened to the design level and the exit to the pit should be made.
The required process equipment, accessories and accessories shall be delivered to the construction site.
Methods and sequence of work execution.
BNS fabrication is performed in the following sequence.
Drilling machine is installed on BNS manufacturing point. During penetration of the first 3 m of the well, soil to the surface is supplied by the working tool of the drilling rig 1BA15N.01. The drilled soil is loaded by a forklift truck into vehicles and taken out of the construction site.
In the process of drilling wells for piles, tool failures should be noted. When fixing a failure, it is necessary to stop the work and inform the author's supervision.
Well bottomhole during drilling shall be brought to design elevations. If the obstacles encountered during drilling above the design level of its bottomhole cannot be overcome, the decision on the possibility of using wells for piling should be made by the design organization.
Upon completion of drilling it is necessary to check compliance with design of actual sizes of wells, elevation of their wellhead, bottomhole and location of each well in plan, and also to establish compliance of soil of base with data of engineering and geological surveys (if necessary with the help of geologist). Scan results are recorded in the working log.
Prior to installation of the reinforcement frame and after its installation, the well shall be inspected for loose soil in the bottomhole, showers, dislocations, water and sludge.
Pile concreting is permitted only after inspection and execution of concealed drilling and reinforcement acts.
Pile concreting shall be carried out not later than 24 hours after completion of drilling. If concreting is impossible within the specified terms, drilling of wells should not be started, and those already started should be stopped, without bringing them by bottomhole by 1-2 m to the design level.
BNS concreting is performed by the method of vertically movable pipe (NRMM) and consists of the following operations:
- Reinforcement frame with fixators of well pile position is installed in the finished well for guaranteed creation of protective layer of concrete with thickness of 5060mm on pile shaft.
- Concrete mixture is laid in the well by the NRMM method. For concreting, a receiving hopper with a concrete cast pipe with a diameter of 250325 mm is used. The volume of the hopper shall not be less than the internal volume of the concrete-cast pipe. Joints of concrete-cast pipe sections shall be sealed. If there is (before concreting) water in the well with a layer of more than 20 cm, the concrete-cast pipe shall be equipped with a check valve.
Concrete mixture is fed into receiving funnel of concrete-cast pipe by means of non-rotating hopper with capacity of 1.0m supplied to place of concrete laying by car crane. As the well is filled with concrete, the concrete pipe is removed from the well. Compaction of concrete mixture in well is performed by means of vibrators fixed on concrete-cast pipes. The distance between the bottom of the well and the lower end of the concrete pipe at the beginning of concreting should not exceed 30 cm. During concreting, the concrete pipe should be lifted. At the same time, the lower end must be permanently buried under the level of concrete mixture by at least 1 m.
During concreting the concreting pipe shall be permanently filled with concrete mixture. Interruptions in the supply of individual portions of concrete mixture shall not exceed the setting period established by the laboratory at this cement grade and ambient temperature
Concrete mixture should be fed into the well until clean (without sludge) concrete mixture comes to the surface and finished with removal of contaminated layer of concrete mixture.

SNiP 12042002. Labor safety in construction. Part 2. Construction production.
4.2.3 Construction Process Organization and Technology
Readiness of works preceding the foundation arrangement,
In accordance with the requirements of SNiPA 12012004 for the organization of construction, the following works were carried out before the construction of the foundations:
fenced the territory of the construction site with a fence 2m high;
surface water removal from the pit is organized;
access roads and roads are arranged;
household premises are arranged;
2 trips for equipment are arranged;
concrete preparation for foundations has been performed;
reinforcement nets and formwork sets were introduced in an amount that ensures uninterrupted operation for at least two shifts;
acts of foundation foundation acceptance are drawn up in accordance with the executive diagram;
welding devices are connected;
geodetic breakdown of axes and marking of foundation position in accordance with design; hairlines fixing the position of the working plane of the formwork panels are applied to the surface of concrete preparation with paint.
Earthworks are made in the form of solid pit. The natural slope is 2.6 m. The excavation depth is 3.45 m. The calculation is carried out in accordance with the requirements of SNiP 12042002.
The soil moves along the construction site and is laid in the embankment, for the possibility of backfilling. The soil is placed so that it does not interfere with the complex mechanization of the work on the construction of foundations.
Storage and stock of materials.
Shields and fasteners are delivered in accordance with the application. It is drawn up on the basis of the table indicated on the sheet for the first two captures. They are unloaded and stored in the area of the assembly site. The assembly site is a planned and packed section. It is located next to the first two grips so that the assembled enlarged panels and volume blocks can be immediately installed by crane at the place of their concreting.
Rebar grids for the first two and all other grips are started and stacked in sets on each gripper. They are stored on the concrete of the underlying layer. It is desirable to deliver the required formwork and reinforcement in preparation for operation. At the same time, for unloading and storage, the crane selected in item 5 for assembly and rearrangement of the formwork can be used.
4.2.4 Methods and sequence of works execution.
This section discusses the characteristics of the work and imposes basic decisions on the means and methods of its execution.
Installation processes and concreting occur in one shift. First, the formwork is mounted and its reinforcement takes place on the first grip. The next day, it is concreted in one shift.
The next morning, the structures are expanded, and the enlarged formwork shields are transferred to the second grip, waterproofing is applied. On the fourth working day (see Work Schedule), on the first gripping, the railway foundations are installed and the foundations-pillars are arranged for 3 days, side coating waterproofing is applied, while on the second gripping installation processes are started, etc.
Formwork arrangement and reinforcement of foundations.
The basis for the decision is the study of the material in paragraphs 2-5 of the annex and paragraph 2.2. the main part.
Start by dividing the building into grabs and assigning them numbers in the order of work. The gripping plan is shown on sheet 1. The procedure for the capture works is of great importance.
As previously noted in item 2.2, the assembly of formwork and panels up to 1m2 must be carried out on the assembly site. Full assembly of formwork sets is performed in the following sequence:
horizontal grid C-1 is set to the design position;
assembly and installation of lower stage of formwork;
the 2nd degree of formwork is collected;
S2 volumetric frame is installed in the lower formwork box on the pre-installed C-1 grid;
All operations for movement of formwork boards and rebar grids are performed by crane. The crane adopted by the parameters should provide such an opportunity. After assembling and installing all the foundations of the first and second grips, the entire stock of grids, fasteners and shields imported for them is exhausted and the need for an assembly site disappears.
After concreting the foundations of the first grip and holding the concrete, the formwork on each of the foundations is disassembled by large blocks using a crane, cleaned, lubricated, rearranged to the next grip and reassembled here. For the first grip, the next is the second, for the second - the fourth, for the third - the fifth, etc. This means that in order to allow the crane to rearrange the formwork from the gripper to the gripper at the selected departure and lifting capacity of the crane, the third gripper must be in the gripper plan next to the first, the second near the fourth, etc., that is, within the crane range.
In places where the crane booms are not enough to move the formwork from the grip to the grip, it is transported by transport with loading and unloading by a selected crane.
The crane installing the formwork immediately performs reinforcement of the foundations with nets introduced and laid in advance by separate units on the construction site. Since the C-2 nets are welded into a three-dimensional frame on each grip, when the crane is relocated, the welding transformer must move with it and the cable must be dragged to connect it.
Concreting of foundations.
The general plan of the foundations shows the path of concrete laying equipment, parking, places of example concrete, etc. Also the sections with characteristic moments of works are presented.
First portions of concrete mix enter lower stage along perimeter. The mixture is then fed through a receiving hopper and link hobs slowly and even intermittently in 11.5 hours. The mixture is subjected to vibration compaction by internal vibrators immersing them in the mixture through open faces of the lower stage and repositioning them along the perimeter of the stage towards the center of the foundation. Vibration compaction of the second stage concrete is carried out similarly, after which they are smoothed. Concrete mixture can be laid in pylons immediately after completion of laying in stages. Mixture in columns is compacted by internal vibrators lowering them from above.
In the course of keeping take care for concrete which provides: maintenance of the temperaturnovlazhnostny mode, prevention of considerable temperaturnousadochny deformations and formation of cracks, protection of the hardening concrete from blows, concussions, and other undesirable influences.
In summer, concrete on ordinary Portland cements is watered for 7 days. At air temperature above + 15 ° C during 3 day, watering is carried out every 3 hours and once at night, and in subsequent days - at least three times a day.
4.2.5 Work schedule.
The work schedule was drawn up on the basis of the in-line performance of work, calculations and decisions made on the turnover of the formwork, the schedule is located on sheet No. 6.
4.2.6 Methods and methods of labor of workers
Formwork arrangement.
The formwork is installed from shields, which are connected before installation in rectangular boxes by means of wire ties and spacers. Two bridges are laid on the lower stage box on the width of the next stage.
Boxes of the second and overlying stages have elongated lower boards, by means of which they rest on underlying boxes.
To reduce the adhesion of the formwork to concrete, the front surface of the installed formwork is covered with lubricant - lime milk, an aqueous solution of fatty clay, treated with mineral oils. The cladding of the formwork shall be lubricated prior to installation of the fittings. Accuracy of formwork installation is checked taking into account permissible deviations from nominal dimensions.
