摘要

静压法施工是通过静力压桩机的压桩机构以压桩机自重和机架上的配重提供反力而将桩压入土中的沉桩工艺。由于这种方法具有无噪音、无振动、无冲击力等优点，适应今后岩土工程的要求；同时压桩桩型一般选用预应力管桩，该桩作基础具有工艺简明，质量可靠，造价低，检测方便的特性。随着静压管桩技术的广泛应用，以及对静压管桩的理论研究、设计和施工经验的不断积累，其应用的技术水平也会不断提高，在工程中也将发挥更好的经济效益。建设工程预应力混凝土管桩的应用较为广泛，因此，因此预应力混凝土管桩的施工质量问题也倍受关注。本文结合工程实际施工，对预应力管桩静压施工进行了论述，说明了管桩静压施工中质量控制要点，并结合测桩试验，对先张法预应力管桩静压施工质量提出控制方式、方法。

Abstract

The static pressure method construction is pile pressing mechanism through the static pile pressing machine with pressure balance pile machine weight and the rack with force and the pile soil pile sinking process. Because this method has advantages of no noise, no vibration, no impact force, adapt to the future of geotechnical engineering requirements; at the same time pressure pile is generally used in prestressed concrete pipe pile, the pile foundation is concise, reliable quality, low cost, convenient detection characteristics. With the wide application of static pile technology, and accumulated on the static theory research, design and construction experience, the application level of technology will continue to improve, in the project will also play a better economic benefit. Application of construction of prestressed concrete pipe pile is widely, therefore, the construction quality of the prestressed concrete pipe pile is also paid close attention to. In this paper, combined with the actual construction project, the construction of prestressed pipe pile static pressure are discussed, the key points of quality control in the construction of pile static pressure, and combined with the testing of pile test, the control mode, method of pretensioned prestressed pipe pile with static pressure construction quality.
