Abstract:Based on the engineering practice, a construction technology of trenchless pipeline inspection well is introduced in detail. Compared with the traditional open caisson method and reverse construction method, this technology has less impact on the surrounding environment, faster construction speed and reusable support structure, which can greatly improve the construction efficiency and reduce the engineering cost. The theoretical calculation of fixed end arch and the engineering measurement analysis certify that this technology can meet the construction requirements and has the higher application value.
