案例分析计算某砖混结构住宅土方分部各分项工程的工程量。(Case study to calculate the quantity of each sub item of the earthwork division of a brick concrete structure house.)
Case study: to calculate the quantity of each sub item of the earthwork division of a brick concrete structure house.
First, key words: case analysis, calculation of earthwork division of each sub project works.
Two, Abstract: a masonry structure, reinforced concrete strip foundation, according to the requirements of meter and list pricing norms requirements, the project list segment respectively and calculate the earthwork quantity.
Three, related knowledge points:
In the earthwork, how to apply the quota items?
Dig and fill earthwork thickness within 300mm and leveling leveling apply within the item; trench bottom width is less than 3m, the long groove bottom is 3 times larger than the width of groove bottom of the excavation to dig trench geosyncline, sub; pit bottom in the area of 20 meters within the set of base pit digging; apply are digging party item above scope the.
How is the depth of excavation determined?
The depth of excavation is based on the elevation of the designed outdoor floor to the dimension of the bottom of the underlying cushion.
How to divide dry soil and wet soil?
Division of dry soil and wet soil should be based on the geological survey data as the standard, if there is no data to the underground water level above the water level as the standard, often for dry soil, water is wet soil, using artificial lowering underground water, soil water in dry wet partition prevail.
How to the meter, dig trench, medium trench backfill, backfill ground engineering calculation?
The construction of the site shall be based on the outer edge of the outer wall at the bottom of the building, with 2m added to each side and calculated in square meters.
The groove quantity is calculated by the slot length and the cross sectional area. Groove length: the exterior wall is calculated according to the length of the base cent
