Strong foundation for you to explain the RCP strong composite foundation treatment technology

The RCP strong composite foundation treatment technology developed by Qiangqiang Foundation Company integrates the advantages of sand and stone pile, cement and soil rotary shotcrete mixing pile and rigid pile. According to the soil quality conditions and soft foundation treatment requirements, a variety of combination methods are adopted to optimize the pile diameter, pile length, ash content, aggregate grading and other parameters. It can give full play to the friction resistance and end resistance of the soil around the pile and match the strength of the pile material to produce high enough bearing capacity of a single pile.

The technology of drilling cast-in-place pile for construction of strong foundation pit retaining pile

The MUD wall protection hole filling pile is a pile that is replaced by underwater concrete pouring after the hole is formed by slowly drilling through the pile machine under the condition of mud wall protection, taking the drilling slag out with mud and protecting the hole wall from collapsing. Construction without vibration, no compaction, low noise, suitable for use in urban built-up areas and other advantages, widely used in foundation pit retaining pile.

Share the knowledge of static pile technology for strong foundation

Static pile pressing refers to the method of pressing precast piles into the soil one by one using static pressure (dead weight and counterweight of pile driving machine). This method saves reinforcement and concrete, reduces the project cost, and the strength grade of concrete can be reduced1~2Grade, the reinforcement is more economical than the hammer method, and the construction of no noise, no vibration, no pollution, small interference to the surrounding environment, suitable for soft soil areas, urban centers or densely built pile foundation engineering, as well as the expansion of precision factories.
