Foundation pit supporting construction in Shanghai

The main forms of foundation pit supporting construction in Shanghai area are as follows: 1. Steel sheet pile Steel sheet pile is one of the most widely used deep foundation pit supporting structures in Shanghai soft soil base area. Larsen steel sheet piles are commonly used for hot rolled U-section, which can be used to excavate foundation pits with a depth of 5 ~ 10 meters. Because the one-time investment is larger, it is more rented in the form of lease, after use, pull out and return. The types of steel sheet piles used by each construction unit combined with the characteristics of the project are as follows:

Prevention and control measures for quality problems of long auger bored pile

1) Hole wall collapse: hole wall collapse due to poor soil quality of pile position or groundwater seepage. Before excavation, the site soil should be excavated in staggered pile positions, shorten the height of each section and observe the soil looseness at any time. If necessary, the slump hole can be blocked with brick, steel sheet pile and wood pile. The operation process should be compact, leaving no spacing and avoiding slump.
