Chapter IV, the main project construction methods and technical measures
I, foundation engineering
1, construction process
Site leveling → positioning and placing lines → trench excavation → supporting formwork → pouring concrete bar foundation → inspection and acceptance → removal of the formwork → backfill → moisture-proof layer → acceptance of the foundation structure.
①Wherein: earth excavation process is as follows:
Positioning measurement--Burying axial lead pile--Spreading out excavation line--Manual excavation --Foundation trench inspection --Foundation abnormality treatment --Entering the next process.
2, construction points
1) The amount of soil in the process of earth excavation, in the vicinity of the site near the pile, in order to be used for backfilling.
2) In the process of excavation, the surveyor readily leveled and nailed elevation control piles on the pit wall to keep track of the excavation depth and prevent over-excavation.
3) When digging, the distribution of underground pipelines should be explored in advance and properly handled.
4) In earthwork construction, attention should be paid to the safe use of construction machinery and overhaul before entering the site. Excavators are not allowed to carry out other operations within the scope of work when excavating, when loading soil, the driver of the car should leave the cab, and it is strictly prohibited to load soil when there are people in the trunk.
②This project is C20 concrete.
To be based on the axial dimensions, the base elevation acceptance after the hidden inspection procedures, survey and put the personnel in a timely manner to mark the 400mm thick concrete on the skin of the elevation control line. Before pouring the concrete, check whether the size and shape of the bedding layer is correct and whether the template support is firm. When pouring the bedding concrete, send a person to randomly check the quality of commercial concrete at any time. The surface of the concrete is scraped with a scraper, and then rubbed and calendared with a wooden trowel, and samples should be taken in time during the construction process, and test blocks should be retained.
3 earth backfill
After the completion of the foundation project, after the quality inspection station acceptance, then the earth backfill.
1) Process
Basic cleaning → inspection of soil quality → layered paving, raking → tamping and compacting → inspection of compactness → repair and leveling → acceptance.
2) Construction method
The bottom of the base trench should be cleaned of garbage and other debris before filling. Before backfilling the foundation, it must be cleaned up to the elevation of the bottom of the foundation, and the loose garbage, mortar, stones and other debris falling back should be cleaned up.
Check the backfill soil with or without debris, whether the particle size is in accordance with the provisions of the water content is within the scope of control. If the water content is high, can be used to turn loose, drying and uniform mixing of dry soil and other measures; in case of backfill soil water content is low, can be used in advance sprinkler wetting and other measures.
After all the filling is completed, the surface should be leveled, and the place over the design elevation should be shoveled in time according to the line, and the place lower than the design elevation should be made up with the soil and compacted.
3) Quality standard
Main control items: the permissible value of elevation deviation -30mm, compaction coefficient of layering in accordance with the design requirements.
General items: backfill soil material, must be in accordance with the provisions of the design or construction specifications, layering thickness and moisture content in accordance with the provisions of the design or construction specifications, the permissible deviation of the surface flatness is not more than 20mm.
Two, fence project
Laying out the line→supporting the mold→pouring concrete base→maintenance, mold removal→laying brick columns→installing and fixing the iron railing
( 1）Foundation bedding concrete
Foundation concrete construction must be the concrete bedding and the surface clean, no water, no soil falling into the groove, the side of the template support in the pit wall need to pay attention to the stability of the reinforcement, shall not be the template support bar directly supported in the soil wall, support the lower mouth must be added pads support in the dense soil layer, in order to prevent the pouring of concrete due to the support of the mold run. Foundation beam template, can use diagonal bracing plus buttresses way to reinforce, beam upper mouth specially made bayonet steel or angle should be limited to its width.
When the foundation concrete is poured, no construction joints are left.
(2) brick foundation
Brick foundation construction before the foundation beam side backfill, should avoid the soil scattered in the foundation beam, such as the foundation beam should be cleaned up the mouth of the foundation beam, popping out the brick foundation of the center line and side lines, on a layer of cement mortar, the foundation beam on the upper mouth of the wall parts of the local unevenness of the place to leveling, and then laying bricks to lay the wall. Can also be brick foundation masonry is completed, and then backfill, keep the brick foundation masonry stage of the original concrete surface clean, so that the quality of masonry to get further guarantee.
Three, the main structure project
