YTHG金属波纹管涵采用标准化设计,设计及生产过程简单,施工周期短。适应变形能力比较强,对地基的承载能力及平整度要求相对于普通桥涵结构较低,工程造价比同类跨径的桥涵低,在现代桥涵施工中,特别是在工期紧的项目中,YTHG金属波纹管涵是普通小型桥涵理想的替代结构形式。本文结合YTHG金属波纹管涵自身的特点,主要阐述其施工工艺及具体作业步骤,为实际施工提供指导。
YTHG metal bellows culvert with standardized design, design and production process is simple, short construction period. Adaptability to deformation is relatively strong, bearing capacity and flatness requirements of the foundation relative to the ordinary bridge and culvert structure is lower, the cost of the project is lower than that of similar span bridge and culvert, in the construction of modern bridges and culverts, especially in tight project schedule, YTHG metal Bellows culvert is an ideal alternative structure for ordinary small bridges and culverts. In this paper, YTHG metal bellows culvert own characteristics, mainly elaborated on its construction technology and specific operating steps, to provide guidance for the actual construction.
