背景技术Background technique
随着浅海海上油田的不断开发,海底管缆和电缆已经成为重要的开发设施,由于浅海海域场区海洋动力、浅层工程地质、海底动力地貌条件十分复杂,在波流的反复冲刷下,海底软地基发生复杂变化,造成大量海底管道、海底管缆底部附近出现悬空现象,容易导致海底管道和海底管缆疲劳断裂。With the continuous development of shallow offshore oilfields, submarine umbilicals and cables have become important development facilities. Due to the complex marine dynamics, shallow engineering geology, and submarine dynamic geomorphology conditions in the shallow sea area, under the repeated erosion of waves and currents, the seabed will The complex changes in the soft foundation have caused a large number of submarine pipelines and submarine umbilicals to appear suspended near the bottom, which can easily lead to fatigue fractures of submarine pipelines and submarine umbilicals.
针对海底管道存在的安全隐患,目前,通常采用回填掩埋、回填后水泥或放生水草加固、桩支撑等方式进行隐患治理,但无论哪种方式,回填掩埋是不可或缺的方法。针对回填施工,现有的回填模式通常采用“人工投掷、潜水员进行二次整理”的方式,其不符合安全施工要求,且回填效率较低,回填量及回填有效性均无法控制。In view of the hidden safety hazards of submarine pipelines, at present, the hidden dangers are usually treated by backfilling, cementing or releasing aquatic plants after backfilling, and pile support, but no matter which method, backfilling is an indispensable method. For backfilling construction, the existing backfilling mode usually adopts the method of "manual throwing and secondary finishing by divers", which does not meet the safety construction requirements, and the backfilling efficiency is low, and the amount and effectiveness of backfilling cannot be controlled.
