一，波纹钢管整体圆管涵（螺旋波纹钢圆管） 
（1）检查波纹钢管的规格、长度和整衢州plane.
Seventh, the need for "cold tight" compensators, the pre-deformation of the auxiliary members should be installed after the pipeline can be removed.
Eight, it is forbidden to use the method of corrugated compensator deformation to adjust the installation of the pipeline, so as not to affect the normal function of the compensator, reduce the service life and increase the load of the pipe system, equipment, and supporting components.

体外观质量，不符合设计要求和管体损坏的不得使用。 
（2）检查涵管底部基础平整度、密实度、标高和预留拱度的设置，确定涵洞位置、中心轴线和中点。 
（3）在保证中心轴线和中点重合的前提下,管节排放从一侧起逐节排放,管节连接时端部对齐、法兰端面平行，旋转和平移管体对齐法兰螺栓孔，端面间置入弹性密封件，用配供的螺栓螺母均匀收紧,保证连接强度和密封。 
（4）每连接3～5节应检查涵管位置和管体姿态，可以用千斤顶或
