Foundation works, according to the authoritative definition of the National Scientific and Technical Terminology Validation Committee, refers to the use of engineering measures to change or improve the natural conditions of the foundation to meet the design requirements.
Foundation construction process:
Positioning→ paying review (including axis, coordinates), → pile machine (selection) in place→ piling → pile detection→ excavation of foundation trenches→ pile breaking→ leveling→ pouring concrete cushion → axis leading→ platform formwork and beam bottom formwork installation→ steel bar safety → bearing side formwork and foundation beam side formwork installation→ foundation formwork, steel bar acceptance→ pouring foundation concrete → maintenance→ foundation brick masonry→ backfill
Three links and one level refer to the prerequisites for the start of capital construction projects, specifically referring to: water, electricity, road and site leveling. Water pass (specifically refers to water supply); Dentsu (refers to the construction of electricity connected to the construction site to meet the construction conditions); Road access (refers to the off-site road has been paved to the entrance around the construction site to meet the vehicle access conditions); Site leveling (refers to the proposed building and conditions site is basically flat, no mechanical leveling, manual simple leveling can enter the state of construction), referred to as three links and one level.
