Slope Support Features in Deep Foundation Pit Engineering

1. Support difficulty of slope support is large.

With continuous development of economy and society, the demand of buildings’ structures and quality is higher. At the same time, foundation pit engineering is developing in a direction of large span, great depth and large area, which will all increase slope support difficulty in deep foundation pit engineering.

2. Construction period of deep foundation pit slope support is long.

Compared with common construction project, slope construction of deep foundation pit is longer. It will cost several months from excavation to engineering completion and acceptance. During this period, many factors will influence on stability of deep foundation pit support, such as surrounding windrow, rainfall, mechanical vibration, etc.

3. Influence on surrounding environment is big.

Because of construction underground, slope support in deep foundation pit engineering has great influence on surroundings. Distance control and slope stability has high demand. If two deep foundation pit slope are constructed at the same time, the restraint and influence between each other are bigger and construction difficulty will be increased.

4. Construction regionalism of deep foundation pit slope support is strong.

Hydrology and geological condition in every area have large difference. So when designing and constructing, surrounding hydrology, geological condition and pipelines should be explored and checked carefully and then confirm supporting form and construction scheme.

5. Slope support has close relation with soil excavation.

Deep foundation pit engineering consists of design and construction of soil excavation and slope support system. Construction of soil excavation has great influence on support quality.

Self drilling bolt system products combine drilling, grouting and anchoring together, with high efficiency and convenience. They have small construction limit and can be operated in narrow area, bonding strength is good and supporting quality is high. So, self drilling bolt system has good supporting effect in deep foundation pit engineering.
