| Abstract: | The construction technology of drilling and compression-type bladder-type branch piles is based on the original drilling or sinking of the hole into the pile foundation,make full use of the resistance of the soil along the pile set a number of branches to increase thepile side friction to improve the bearing capacity of concrete piles.This paper introduces the construction principle,technical characteristics and main points of the construction technology of the drilling and compression type compression pile,and provides some technical guidance for similar projects. |
