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.

Strong foundation construction technology of TRD Equal thickness cement-soil mixing diaphragm wall technology (TRD construction method)

The TRD method is to insert the cutting box with cutting chain and cutter head into the ground to the designed depth, and inject cement slurry into the soil while cutting vertically and pushing laterally into the groove, so that the cement slurry can be cut and stirred with the original soil to form the continuous wall under the cement soil with equal thickness, which is suitable for clay, sand and other soil layers.

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.

Strong foundation interpretation ground treatment knowledge point: dynamic consolidation method

Dynamic compaction method is one of the more common ground treatment methods, it is to use a few tons to dozens of tons of heavy hammer falling from height, repeatedly ramming the ground for many times, the foundation for strong tamping. This powerful ramming force in the foundation middle vivid stress and vibration, from the ramming point sent out longitudinal wave and transverse wave, to the depth of the foundation direction propagation, so that the foundation shallow and deep layer of different degrees of reinforcement.
