Method for dredging drainage pipeline through dry ice micro-explosion
The invention provides a method for dredging a drainage pipeline by adopting dry ice micro-explosion, which comprises the following steps: step 1, assembling and connecting a dry ice cleaning machine; step 2, lowering and walking the dry ice cleaning machine in the pipeline; step 3, carrying out dry ice micro-explosion cleaning on a to-be-dredged pipe section: controlling the dry ice cleaning machine to walk to a to-be-dredged part through a ground console, and carrying out dry ice micro-explosion cleaning on the to-be-dredged pipe section; the air compressor and the dry ice storage machine are started, dry ice particles enter the dry ice cleaning machine through the rubber hose and are sprayed to the inner surface of the pipeline through a dry ice nozzle of the dry ice cleaning machine, dry ice absorbs heat to generate micro-explosion, the micro-explosion force of the dry ice is utilized to enable deposits to be separated from the inner surface of the pipeline, and therefore the purpose of dredging is achieved. And the whole process is operated on the ground, operation is convenient, manual well descending is not needed, and the personal safety of workers is guaranteed.
本发明提供了一种采用干冰微爆进行排水管道清淤的方法，它包括以下步骤：步骤1，干冰清洗机的组装连接：步骤2，干冰清洗机在管道内部的下放和行走：步骤3，待清淤管段的干冰微爆清洗：通过地面控制台操纵干冰清洗机行走至待清淤部位，开启空气压缩机和干冰存储机，使得干冰颗粒通过橡胶软管进入干冰清洗机内，通过干冰清洗机的干冰喷嘴喷射到管道的内表面，干冰吸热产生微爆，利用干冰的微爆力使淤积物从管道内表面脱离，从而达到清淤的目的。而且实现了排水管道清淤自动化，整个过程均在地面操作，操作方便，无需人工下井，保证了工人的人身安全。
