周口市东新区引黄调蓄工程土方处置方案设计研究

Study on Design of Earthwork Disposal Scheme for the Yellow River Diversion and Storage Project in Dongxin District of Zhoukou City

调蓄工程能够解决需水来水过程不匹配、用水引水不协调的局面。在开挖调蓄水库的过程中往往存在大量的土方作业,如何有效处置好大量土方的开挖回填弃运等工作是决定调蓄工程设计成败的关键。基于此,本文以周口市东新区引黄调蓄工程为例,分析介绍合理经济的土方处置方案,通过比选,调蓄工程采用排水开挖方案进行成湖施工,弃土方案采用集中堆放与回填周边洼地相结合的处置方案。

The regulation and storage project can solve the problem of incompatible water supply process and incom. patible water diversion. In the process of excavation and storage of reservoirs, there are a lot of earthwork, how to deal with the excavation, backfilling and discarding of a large number of earthwork effectively and reasonably is the key to the success or failure of the project design. Therefore, this paper took the project of diversion and storage of the Yel. low River in Zhoukou Dongxin District as an example to analyze and introduce a reasonable and economical earth. work disposal scheme, through comparison, drainage excavation scheme was adopted for Lake construction, and cen. tralized stacking and backfilling of surrounding depressions were adopted for disposal of waste soil.
