Main engineering construction methods and technical measures
A, basic engineering
1, construction technology
Site leveling → positioning and setting out → foundation trench excavation → formwork erection → pouring concrete strip foundation → inspection and acceptance → formwork removal → backfill soil → moistureproof layer → foundation acceptance.
① Among them, the earthwork excavation process is as follows:
Positioning survey-burying axial pile-spreading excavation line-manual digging-foundation trench inspection-foundation abnormality treatment-and entering the next process.
2. Key points of construction
1) The earthwork volume during earthwork excavation shall be piled up near the site for backfilling.
2) During excavation, surveyors should level the site at any time, and nail elevation control piles on the pit wall, so as to grasp the excavation depth at any time and prevent overbreak.
3) When excavating, find out the distribution of underground pipelines in advance and handle them properly.
4) During earthwork construction, attention should be paid to the safe use of construction machinery, and maintenance should be carried out before entering the site. During excavation, other operations are not allowed within the working scope of the excavator. When loading soil, the driver should leave the cab, and it is forbidden for anyone in the trunk to load soil.
② This project is C20 concrete.
After the foundation axis size and basement elevation are accepted, the measuring and setting-out personnel shall mark the elevation control line of 400mm thick concrete epithelium in time. Before concrete pouring, check whether the size and shape of cushion are correct and whether the formwork support is firm. When pouring cushion concrete, assign personnel to randomly check the quality of commercial concrete at any time. The concrete surface shall be leveled with a scraper, and then leveled with a wood trowel for calendering. During construction, samples shall be taken in time and test blocks shall be reserved.
③ Earthwork backfilling
After the foundation project is completed, earthwork backfilling shall be carried out after the acceptance of the quality inspection station.
1) process
Grassroots cleaning → soil quality inspection → layered soil spreading and harrowing → compaction → compactness inspection → trimming and leveling → acceptance.
2) Construction method
Before filling the soil, the garbage and other sundries at the bottom of the foundation trench should be cleaned up. Before backfilling the foundation, it must be cleaned to the elevation of the bottom surface of the foundation to remove loose garbage, mortar, stones and other sundries.
Check whether there are sundries in the backfill, whether the particle size meets the requirements and whether the water content is within the control range. If the water content is high, measures such as loosening soil, airing and mixing dry soil evenly can be taken; When the water content of backfill soil is low, measures such as watering and wetting in advance can be taken.
After the completion of filling, the surface shall be leveled by pulling wires, and the places exceeding the design elevation shall be leveled by lines in time, and the places below the design elevation shall be filled and compacted.
3) Quality standard
Main control items: the allowable value of elevation deviation is-30mm, and the layered compaction coefficient meets the design requirements.
General project: Backfill materials must comply with design or construction specifications, layered thickness and water content should comply with design or construction specifications, and the allowable deviation of surface flatness is not more than 20mm.
Second, the fence project
Pay-off → formwork support → cast-in-place concrete foundation → maintenance and formwork removal → bricklaying column → installation and fixation of wrought iron railings.

During the construction of foundation concrete, the concrete cushion and surface must be cleaned, and no water or soil can fall into the groove. When the side formwork is supported on the foundation pit wall, attention should be paid to the stability of reinforcement. The formwork support rod cannot be directly supported on the soil wall, and the support lower mouth must be supported on the dense soil layer with a cushion block to prevent the formwork from running off when pouring concrete. The formwork of foundation beam can be strengthened by diagonal bracing and opposite bracing, and the width of bayonet reinforcement or special angle steel at the upper mouth of beam body should be limited.
When pouring foundation concrete, no construction joints shall be left.
(2) Brick foundation
Before the construction of brick foundation, when backfilling the side of foundation beam, soil should be avoided from scattering on the foundation beam. If so, the foundation beam should be cleaned up, the center line and sideline of the brick foundation will pop up, a layer of cement mortar will be laid to level the local unevenness of the foundation beam upper wall, and then the brick wall will be built. It is also possible to fill the soil after the brick foundation is laid, so as to keep the original concrete surface clean during the brick foundation laying stage and further ensure the laying quality.
