Only by laying a good foundation can we build the wall up, and a good foundation can withstand high floors, so the foundation and foundation engineering to build the foundation is particularly important in the construction project. But as the basic engineering of the building, everyone does not know about the foundation and foundation engineering, then the following Xingye Haoda Xiaobian will introduce the foundation and foundation engineering from three aspects such as content, construction technology and process, and then we will understand it together.

1. Foundation and foundation engineering mainly includes the following:

1. No support earthwork

2. There is a supporting earthwork

3. Foundation treatment

4. Pile foundation

5. Underground waterproofing

7. Concrete foundation

8. Masonry foundation

9. Jingang (pipe) concrete

2. Introduction to foundation and foundation engineering construction technology:

1. Concrete chute construction technology - the advantages of this technology: (1) Chute pouring concrete belongs to the non-pumping category, which can greatly reduce the concrete slump, reduce the unit water consumption, and avoid the phenomenon of concrete shrinkage. (2) The use of chute pouring concrete is more conducive to the heat dissipation of large-volume concrete in summer construction, and reduces the temperature and hydration heat of molding. (3) The pouring of concrete in the chute can avoid the blockage of the conventional construction pump pipe, and the ergonomics are higher, which can ensure the continuous pouring of large-volume concrete.

2. Basement roof post-pouring with pre-sealing technology - the advantages of this technology: in order to backfill the basement roof in advance, provide construction sites and roads.

3. Cancel the post-pouring belt construction technology - the advantages of this technology: (1) Improve the quality. (2) Shorten the construction period. (3) Cost saving.

4. Different forms of tower crane foundation design and construction technology - the advantages of this technology: improve the bearing capacity of the pile, shorten the length of the pile, reduce the cost and accelerate the construction progress.

5. Selection and application of water-stop curtain form - the advantages of this technology: short construction period and low requirements for construction conditions.

3. Introduction to the construction process of foundation and foundation engineering:

Positioning and paying, a review (including axis, coordinates), a pile machine (selection) in place→ piling → pile measurement→ excavation of foundation groove→ pile breaking, pile head 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 accept→ance, pouring foundation concrete one maintenance→ foundation brick masonry→ backfill.

The above is a detailed introduction to the content of foundation and foundation engineering, construction technology and construction process, after reading these contents, everyone has a general understanding of foundation and foundation engineering.
