基于疏浚土资源化利用技术的入库航道清淤工艺

Desilting process for inbound channel based on resource utilization technology for dredged soil

随着使用年限的增加,入库航道处淤积越来越严重,为提高灌溉供水能力、满足水质需要、增强纳洪防洪能力,需及时对入库航道进行清淤。由于入库航道清淤疏浚土不像河、海区域那样进行水运抛卸,需要转运上岸处理,因此疏浚土处理工艺繁杂、成本较大,且普遍存在堆存区有限、环境污染而无法满足工程清淤要求情况,影响航道清淤的正常推进。本文针对入库航道清淤疏浚土处理困难的问题,通过结合疏浚土资源利用技术、优化清淤工艺达到正常推进清淤施工的目的,该工艺既可推进入库航道清淤的正常实施,又可满足资源的合理化利用,因此,在入库航道清淤工程中可以广泛推广。

Siltation at inbound channels becomes increasingly serious as the service life of the channels increases. Improving the irrigation and water supply capacity of the channels, meeting the needs of water quality, and enhancing the flood absorption and flood control capacity necessitate the timely desilting of the inbound channels. Dredged soil produced by the desilting of the inbound channels defies transportation and unloading by water as in river and sea areas. Instead, it requires transportation onto the shore for treatment, resulting in complicated and costly treatment process for dredged soil. Moreover, failure to meet the desilting requirements of the projects due to limited stacking area and environmental pollution is common, which further affects the normal promotion of channel desilting. To address the problem of the difficult treatment of dredged soil during the desilting of inbound channels, this paper adopts the resource utilization technology for dredged soil and optimizes the desilting process to achieve the purpose of normally promoting desilting construction. This process can not only promote the normal implementation of the desilting of inbound channels but also meet the requirements of rational utilization of resources. Therefore, it deserves extensive popularization in the desilting projects for inbound channels.
