Abstract

The invention relates to a construction method for combining a river channel crossing a site with a permanent drainage pipeline, firstly, adopting earthwork slope excavation to measure the trend and the slope of the river channel crossing the site, paying off and positioning; secondly, adopting a concrete box culvert structure with a transverse cross section in a shape like a Chinese character 'pin', along with river construction, adding a secondary recovery pool structure at water points in the field to meet the water demand in the field, and finally backfilling and compacting earthwork and hardening the pavement after the construction of the structure is finished. The cross section of the invention can be backfilled and hardened after the construction of the transverse cross section 'V' -shaped concrete box culvert structure is completed, thereby improving the river crossing commute efficiency and reducing the risk of personnel falling into the river.
