预应力混凝土管桩在桥头路基段的应用

Application of prestressed concrete pipe pile in bridgehead subgrade section

在道路工程建设中,桥头路基段的地基处理效果对于减小桥头路基差异沉降具有重要意义。预应力混凝土管桩方案通常用于浙江省道路建设项目的桥头路基段的地基处理。在保证预应力混凝土管桩整体工程质量的前提下,在一定程度上提高工程施工效率的同时,具有较高的成桩质量。基于此,文章从科学的角度出发,结合宁波市某市政道路项目经验,探讨预应力混凝土管桩在桥头路基段地基中的应用。

In road engineering construction,the effect of foundation treatment of bridge head subgrade is of great significance to reduce the differential settlement of bridge head subgrade.The prestressed concrete pipe pile scheme is usually used in the foundation treatment of bridge head subgrade of road construction projects in Zhejiang Province.Under the premise of ensuring the overall engineering quality of prestressed concrete pipe pile,it can improve the construction eficiency to a certain extent and have a higher quality of pile formation.Based on this,from a scientific point of view,combined with the experience of a municipal road project in Ningbo City,this paper discusses the application of prestressed concrete pipe pile in the subgrade of bridge head.
