Underwater sinking pipe construction method
The invention relates to an underwater sinking pipe construction method. The method comprises the following steps: 1) construction preparation and survey setting-out; (2) excavating a foundation trench and pumping sand; 3) steel pipe assembly welding, pressure testing and corrosion prevention; 4) hoisting the river-crossing pipe to enter water; (5) pipe transverse and pipe sinking; 6) closing water and testing pressure of the pipeline; (7) pipe pressing and gravel backfilling; and 8) riverbed leveling and completion acceptance. The construction method has the advantages that the steps are clear, implementation is convenient, underwater pipe sinking method construction is convenient and fast, the requirement for the required construction site area is not high, a pipe sinking construction pipeline is a prefabricated pipeline, the structural quality is good, the construction efficiency is high, construction is safer under the condition of considerable water depth, no special requirement for a construction section exists, and the construction method is particularly suitable for construction of a wide river channel. The underwater sinking pipe construction method is adopted for pipeline river crossing, it is proved in practical application that normal navigation of ships is not affected, construction with complex geological conditions and difficult cofferdam construction can be met, good economic benefits and social benefits are generated, and reference is provided for similar engineering construction.
本发明涉及一种水下沉管施工方法，步骤包括：1)施工准备及测量放样；2)基槽开挖及抽砂；3)钢管组焊、试压、防腐；4)过河管吊装下水；5)横管及沉管；6)管道闭水试压；7)压管及砂石回填；8)河床整平、竣工验收。本发明优点在于：步骤清晰、实施方便，水下沉管法施工便捷，所需施工场地面积要求不高，且沉管施工管道为预制管道，结构质量好，施工效率高，在相当水深的条件下施工更安全，对施工断面也无特殊要求，特别适用于河道较宽河道施工。采用水下沉管施工法进行管道过河，在实际应用中证明了既可不影响船只正常通航，也能满足地质条件复杂、围堰施工困难的施工，产生了较好的经济效益和社会效益，为同类工程施工提供借鉴。
