Abstract: The high-strength prestressed concrete pile (PHC) with its high strength concrete pile, wide adaptability and good impact resistance, penetration, with high capacity, flexural cracking performance, construction of fast, convenient stable and reliable quality, durability, etc., and is widely used in high-rise building foundation. This paper discusses the technical measures in the pipe construction.
Key words: pile construction; technical operations; pile treatment
Introduction:Currently, high-strength prestressed concrete pipe has been applied to housing construction and bridges, piers and other projects. High-strength prestressed concrete pipe (PHC) with its high strength concrete pile, wide adaptability, good impact resistance, penetration, with high capacity, flexural cracking good performance, construction speed, convenience, quality reliability, durability and good, and is widely used in high-rise building foundation. Pipe is soil compaction piles, construction speed, a large number of injections in soft soil area, the soil pore water pressure, excavation without effective control, will cause partial piles, such as the quality of the broken pile accident . Therefore, we must for the quality characteristics of soft soil in the pipe construction, earth excavation techniques and adopt effective measures to guarantee the progress of pile foundation and excavation.


摘 要:高强度预应力混凝土管桩(PHC)以其桩身混凝土强度高,适应性广,耐冲击性能好,穿透力强,具有承载力高,抗弯抗裂性能好,施工快捷、方便,质量稳定可靠,耐久性好等优点,而被广泛应用于高层建筑基础。本文探讨了管桩施工中的技术措施。

引言:目前,高强度预应力混凝土管桩已被推广应用于房屋建筑和桥梁、码头等工程中。高强度预应力混凝土管桩(PHC)以其桩身混凝土强度高,适应性广,耐冲击性能好,穿透力强,具有承载力高,抗弯抗裂性能好,施工快捷、方便,质量稳定可靠,耐久性好等优点,而被广泛应用于高层建筑基础。管桩属挤土桩,施工速度快,软土地区大量施打后,土体超孔隙水压力较大,开挖时如未进行有效控制,将会引起偏桩、断桩等的质量事故发生。因此,必须针对软土地质特点,在管桩施工、土方开挖方面采取有效技术措施,保证桩基质量和挖土进度。
