Cement mixing pile later embedding press-grouting pile support structure and construction method
The invention provides a cement mixing pile later embedding press-grouting pile support structure and a construction method. The cement mixing pile later embedding press-grouting pile support structure comprises cement mixing piles and press-grouting piles, wherein the pressing-grouting piles are intersected with adjacent cement mixing piles. The cement mixing pile later embedding press-grouting pile support structure has the advantages that a support system occupies a small space, is suitable for projects close to red lines on basement outer walls, and has low influence on the peripheral environment; slurry discharge is avoided, and environment protection is facilitated; a good waterproofing effect is achieved, and wall bodies are in seamless connection; the support system occupies a small space, and is suitable for projects close to red lines on basement outer walls; the press-grouting piles have the advantages of high pile-forming efficiency, compact pile bodies, prevention of soil on pile sides, freeness from hole shrinkage and hole collapse, freeness from sediment at the pile bottoms, saving of water and electric power, high pile verticality, high steel bar positioning accuracy and the like; the process structure is simple, the cost is low, the construction period is shortened, and the labor cost is reduced.
