水泥土复合管桩浅析

Analysis of Cement Soil Composite Pipe Pile

水泥土复合管桩是由高喷搅拌法形成的水泥土桩与同心植入的预应力管桩复合形成的获得国家专利的新型复合桩型。水泥土复合管桩不仅桩身材料强度高,还兼有侧阻力大的优点。既可作为基桩使用,也可将其用于复合地基。水泥土复合管桩充分利用原土,且施工时无噪音和污染,经济、环保,适用于粉土、粘性土、素填土、砂土等土层,特别适合软土地基。相比起纯粹的水泥土桩和预应力管桩,适用范围更广,发展前景更广阔,属于绿色建筑基础。

Cement soil composite pipe pile is a new type of composite pile which has obtained national patent and is formed by the combination of the soil-cement pile formed by high spray mixing method and the prestressed pipe pile implanted concentric.Cement soil composite pipe pile not only has the advantages of high material strength,but also has the advantages of large lateral resistance.It can be used as foundation pile or composite foundation.The cement soil composite pipe pile makes full use of the original soil and has no noise and pollution during construction.It is economical and environmental friendly.It is suitable for silt,cohesive soil,plain filling soil,sandy soil and other soil layers,especially for soft soil foundation.Compared with pure cement soil pile and prestressed pipe pile,it is applicable to a wider range and has a broader development prospect.It belongs to the foundation of green building.
