南面沟泵站施工导流的方案比选

泵站施工导流与水文条件、地质条件、交通条件、工程布置和建筑材料等密切相关,常规导流方案一般通过新建临时建筑物来进行导流,利用导流明渠和围堰相结合的方式来保证干场作业,但是新建临时建筑物会增加工程占地与工程投资,对工程的进度造成不利影响。以海南省南面沟泵站为例,提出临时建筑物与永久建筑物相结合的导流方案,与常规方案进行比较,从而选择最佳导流方案。

The Scheme Comparison of the Nanmiangou Pumping Station Construction Diversion

Pumping station construction diversion is closely related to hydrologic condition,geologic condition,traffic condition,project layout and building materials,etc. In conventional diversion scheme,generally,new temporary buildings are usually used for diversion. To ensure the dry operation,the mode of the combination of cofferdam and diversion open channel are used,but the new temporary buildings will increase the project area and the engineering investment. It can cause the adverse effect on the progress of the projects. In this paper,taking the Nanmiangou pumping station of Hainan province as an example,the diversion scheme of the temporary buildings combined with permanent buildings was proposed,which compared with conventional scheme,to choose the best diversion scheme.
