Perform Aerial Work

Monday, February 6th, 2017

Preparation of forest and scaffolding to perform work at height is of great importance both for the safety of high altitude, and for the safety of others. Therefore, preparations for the implementation of the work at height is carried out mainly engineer organization very carefully, allegedly an act of acceptance of forests. Learn more on the subject from Bernard Golden . Scaffolding height: more than 4m allowed the commission to design the act of acceptance; Up to 4m are allowed after acceptance by the head (master) works with the recording in the Journal of acceptance and inspection of forest. Verified: 1. linkages and fasteners for strength and stability, 2. If you are unsure how to proceed, check out Bill O’Grady. good working decks and fences, 3.

uprights 4. reliability of support sites; 5. an earth. Curvature of the struts permitted no more than 1,5 mm per 1m length. Before the crime to carry out work at height of the forest every day, with a break in service after exposure to extreme weather conditions or weather conditions, which adversely affect the integrity of the forest should be inspected by the manager or foreman of works, that is logged receipt and inspection of forest.

As a result of the inspection shall be established: the presence or absence of defects, strength and stability, the presence of barriers, the availability of forests in the future. Daily, and under certain high-altitude work leaves a lot of rubbish – as the accumulation of the winter snow and ice must be to clean floors and staircases. Assembly and disassembly of forests is carried out only on the plan of works subject to a sequence of workers who were specially instructed, failing to foreign territory. Only if all the conditions of high-altitude work will be qualitative, and security is guaranteed.

Parquet

Lags under the cover should be laid perpendicular to the direction of light from windows and in rooms with a definite direction of movement of people (eg, corridors) – perpendicular to the motion. Logs should be joined among themselves flush ends anywhere in the room with the displacement of joints in the adjacent joists not less than 0,5 m between the beams and walls (septa) must leave a gap width of 20-30 mm. In the floor to the ceiling surface of the lag should be lined with a layer of sand, tamping it with sound absorbing pads or lags across their width or length. Logs should address the soundproof layer slabs or sand leveling layer across the bottom surface, without gaps. You can not tamp wooden wedges or pads under the logs for their alignment shall not be permitted support log on wooden pads. Under logs, disposable on the posts in the floor on the ground should be stacked wooden strips on the two layers of roofing, the edges of which should be released from under the pads of 30-40 mm and fasten them with nails. Joints lag should be placed on the posts.

In the doorways of adjacent spaces should be establish an extended lag. It should advocate the partition of at least 50 mm on each side. Boards cover the plank, parquet board, connecting the side edges of a groove, and the parquet panels – with the help of dowels must be tightly pressed against each other.

Implement Construction

If you decide to make repairs in an apartment or house and live in a big city such as Moscow, you probably encounter a problem shopping, delivery and selection of building and finishing material. Because it is very not easy to figure out how to offer the broadest assortment of repair materials, and a huge number of firms, what they offer. How to start a repair – first need to acquire different glue, cement, dry mixture, including possible use in addition walling and roofing materials. A little later, will need to buy finishing materials for walls, ceilings and floors, for example, linoleum, laminate or parquet floor, ceramic tile, wallpaper for walls. Also do not forget that all construction and finishing materials to be delivered. There are two options for further developments. First choice: self-purchase and repair finishing materials, you'll have to go to dozens of organizations, which have to pay not only material, but also supply each of its kind. Second option: use the services of integrated logistics and supply construction and repair materials necessary to you address..

Investigations At Sites Draining

Hydrogeological work and geotechnical testing when shooting are conducted to the extent necessary to justify the reclamation activities and the building structure reclamation system. The total area shooting must be grounded in technical regulations or program of research. Allowed to increase the area of photography compared to the reclaimed area of the object is not more than 1,8 times. It is mandatory to hold Preliminary desk work to assess the materials research of past years, area of study with the objective of the program or technical requirements. Geotechnical and hydrogeological research and studies on the drainage facilities are conducted to determine the causes of waterlogging and temporary excessive moisture, type of water supply in order to select the design decisions on how to drainage area and regulation of water regime. To justify the design solutions for land-reclamation should be examined following the main features of the object: – geomorphology (the structure of floodplains, terraces, valleys, basins, troughs drain; shape and area ratio of low and elevated stations, communications excess moisture from the morphological characteristics of the microrelief, the impact of micro-and macrorelief on waterlogging areas); – geotechnical (lithology and physical and mechanical properties of soils, especially nutrients (peat, sapropel)); – the nature and distribution of geological and engineering-geological processes – hydrological (availability, distribution and depth of aquifers, the hydraulic connection between them and among themselves and with surface water, balance and groundwater regime, their chemical composition, the amplitude of the fluctuations in groundwater level).

Field work must begin with a reconnaissance survey, during which identifies wetlands and redundant, wetlands, examined outcrops, landslide areas, distribution of karst, subsidence and other phenomena, the outputs of groundwater, ravines, etc. Block observations are carried out in two perpendicular directions, taking into account Stretch the major forms of relief, as well as along the river beds, lake and other natural drainage elements. In the process of engineering-geological survey should establish morphogenetic type of relief to which timed swampy land (slope, valleys, plains, etc.), identify the hazardous geological processes. If there are bailing on the territory of the ground-pressure power allowed additional exploration work, the composition and volume of which is justified in each case the program works (technical requirements). Cross-sections perpendicular to the wells should be scheduled during the main geomorphological elements – from the elevated grades (slopes, terraces, etc.) to the receiving water (river, marsh, lake) – a position of extreme well drained outside of the array on the slopes or local watersheds.

The distance between cross-sections should be taken from 500 to 700 m. Well on the alignment should be located at a distance of 300 to 500 meters depending on the geomorphological and geological and hydrogeological conditions. Other distances should be justified in the program or report on research. In the presence of at drainage systems, heavy soils underlain by impermeable, the wells should be drilled on the wing at a depth of 5 m. The number of additional wells in the complex engineering and hydrogeological survey shall not exceed 1.8 observation points (workings) of 1 km2 array drainage for pre-design study, and 2.7 points per 1 km2 array drainage for architectural and construction projects. Well depth is taken as a function of depth aquitard and its power. In case of a pressurized part of the supply wells (40% of the total) should be opened on the roof of the second surface of the aquifer. Depth of the wells should not exceed 35 m.
