1. The master measures the line. According to the design drawings, determine the position of the column head, and use lime along the two lines to position the frame.
2. The excavator digs the foundation. According to the position of the two lines, start digging the foundation. The depth and other issues will be determined according to the drawings and soil quality.
3. Insert the template. After the foundation is dug, the prepared formwork is put in.
4. Put in the steel bars. After the formwork is placed, the steel bars need to be placed, and the steel bars must be fixed according to the drawings.
5. Pour concrete into the formwork. Once the position of the steel formwork has been determined, concrete pouring begins to fix it.
6. After the concrete on the bottom formwork is dry, put in the second layer of formwork. Some deeper columns should be placed in three layers of formwork.
7. Pour concrete into the formwork.
8. Remove the template.
9. Soil backfill.
10. When making floor beams, tie the steel bars first and then nail the formwork. One of the most important materials for making floor beams is steel bars. A lot of steel bars are used, which tests the skills of workers. Tie the steel bars where the floor beams are to be, and then nail the formwork on both sides of the steel bars to fix them. After all the wooden boards are set, the formwork for the floor beams is ready.
11. Pour concrete into the formwork and spread it flat.
12. After the concrete is dry, remove the formwork and the floor beams are ready.
The construction process is generally as follows: site leveling → pile foundation positioning → mechanical entry → pile foundation construction → foundation excavation → foundation cap and ground beam construction → backfilling → superstructure construction
Expand knowledge;
The term civil engineering generally refers to civil engineering, which refers to the planning, construction and maintenance of all infrastructure related to water, soil and culture. Current general civil engineering projects include: housing, roads, waterworks, drainage, flood control projects and transportation, etc. In the past, all civil engineering projects with non-military purposes were classified into this category. However, as engineering science becomes increasingly broad, many contents that were originally within the scope of civil engineering have become independent subjects.
