冬季降水很少，導致很多河道水量很低，有的甚干涸了，為進一步改善河道生態環境，增強來年春季防洪排澇能力，成都市派出多臺挖掘機加長臂對城區部分河道將開展清淤施工，而且為保障施工和效率，施工期間錦江部分水閘將短期停止平壩運行，部分水域可能限流，挖掘機加長臂只需站在岸邊伸長手臂就可輕松完成清淤任務。
There is little precipitation in winter, resulting in low water volume in many rivers, some of which even dried up. In order to further improve the river ecological environment and enhance the flood control and drainage capacity in the spring of next year, Chengdu has sent several excavators and long arms to carry out dredging construction on some rivers in the central urban area. In addition, to ensure the safety and efficiency of construction, some of the Jinjiang locks will stop leveling operation for a short time during the construction period, and some waters may be restricted, The excavator can easily complete the dredging task by standing on the shore and extending the arm.
挖掘機加長臂適用范圍：
Scope of application of excavator extension arm:
（1）加長臂挖掘機拆除高層建筑物。
(1) Long-arm excavator can safely demolish high-rise buildings.
（2）深坑、陡坡挖掘的土方工程，河堤，坡面修整工程。
(2) Earthworks for deep pit and steep slope excavation, river embankment and slope surface finishing works.
（3）市政管網，埋管作業工程，修地鐵、挖隧道遠距離挖掘。
(3) Municipal pipe network, buried pipe work, subway construction, tunnel excavation and long-distance excavation.
（4）溝渠清淤，河道疏通，水電站尾水清淤，較深河道淤泥、碎石的清理。
(4) Dredging of ditches, dredging of river channels, dredging of tailwater of hydropower stations, and cleaning of sludge and gravel in deeper river channels.
（5）拔鋼板樁、水泥樁。
(5) Pull out steel sheet piles and cement piles.
（6）其他對深度、寬度、高度有特別要求的特殊工況。
(6) Other special working conditions with special requirements for depth, width and height.
都知道挖掘機加長臂是河道清理常用的挖掘機機械，靈活操作又效率高，保障好水環境，又能將施工對水環境和景觀的影響降到，挖掘機加長臂真是超乎想象的率。成都市強力推進建設踐行新發展理念的公園城市示范區，持續推進錦江水生態治理提質增效，不斷擦亮公園城市底色，將進一步提升市民的幸福感。
We all know that the excavator extension arm is a commonly used excavator machine for river cleaning. It is flexible and efficient, and can protect the water environment and minimize the impact of construction on the water environment and landscape. The excavator extension arm is really beyond imagination. Chengdu will vigorously promote the construction of a park city demonstration area practicing the new development concept, continue to promote the improvement of quality and efficiency of Jinjiang water ecological management, and constantly polish the background of the park city, which will further enhance the happiness of citizens.
