Mix Spray Application Of Waterproof Curtain Piles

Precipitation under construction in Beijing's policy limit demand for LAITAI building projects Levin too deep pit, high water table, water is very large, sealing foundation conducted research and program optimization technology to determine the use of spray mix waterproof curtain construction of pile technology.Discussion group in the construction process perfected the combination of engineering technology and exceptional circumstances supporting the sealing processing measures; of mixing spray pile design and construction of curtain sealing the existing problems and carry out the necessary tests; explore the mixing jet pile seal curtain of the cost and quality conditions, conduct pilot project, and technical and economic analysis, efforts to control project cost.The technology combines the high-pressure jet grouting pile of jet mixing effects and the advantages of a continuous dense, so waterproof curtain Piles and foundation piling for the full bite, stable quality, low cost single pile, and the construction does not produce a large number of The drilling mud, cement waste reduction and environmental pollution.The project mix waterproof curtain to avoid the jet piles pile or mixing jet set form a continuous curtain separate the waste, with additional solid, high strength, reinforcing the quality of uniform, plus solid shape control, lower costs and better effects, etc., is a more advanced and scientific construction technology, now being promoted has become more available, efficient methods of foundation treatment, is currently the reliable cut-off wall construction technologies.The technology's applications in engineering, to ensure that the construction period, the quality, safety and other goals, meet the national green, environmental protection, energy saving Li Nian, and achieved good economic and social benefits.
