[Abstract]:
The foundation is cast on site, the foundation pit is manually excavated, and the rock part that cannot be manually excavated can be shallow hole by wind or air gun.
1. The foundation is cast on site, the foundation pit is manually excavated, and the rock part that cannot be manually excavated can be shallow hole by wind or air gun.
 
2. The slope of the foundation pit excavation depends on the ground. Before installing the concrete foundation, it is necessary to check whether the size of the foundation pit is appropriate, the plane position and the flatness and compactness of the ground, and then carry out the foundation construction.
 
3 Filling foundation: Before the concrete, the foundation pit is inspected. The contents of the inspection are:
 
1 Base plane position, whether the elevation meets the requirements of the specification.
 
2 Whether the base soil meets the requirements of the specification.
 
3 Whether there is water in the foundation pit, debris, loose soil, whether it is cleaned up.
 
4. After the foundation concrete is poured into the pit, the concrete foundation should be poured as soon as possible. The foundation, the stability and the elevation should be ensured during the foundation pouring: the concrete foundation size of the column is 300mm*300mm*400mm
 
5. Construction method of metal fence mesh column. After the column is completed, the installation according to the basic construction conditions generally adopts secondary watering molding. Firstly, the secondary hole is reserved for the second watering. The size of the reserved hole depends on the diameter of the column. It is larger than the column diameter of 15-25mm and is used as a secondary watering.
 
6. Metal fence mesh construction method: according to the requirements of the foundation and column construction, and then the mesh installation and construction. The construction project is based on the principle of straight line, and at the same time, it is necessary to form a straight slope or oblique draping on the uneven terrain so that there is not too much undulation in the structure.
