大湾水电站调压井设计方案为底坡i＝13％，断面6m ×6m城门洞形螺旋式，洞身长310m。为合理节约投资、节省工期，调压井底板混凝土浇筑后，即作为压力钢管安装运输通道使用。安装单位根据洞身变径、螺旋式特点，巧妙地运用卸车天锚、导向地锚配合卷扬机、滑车系统，顺利完成安装任务，解决了该工程压力钢管运输难题。其经验可为其他类似工程参考。
大灣水電站調壓井設計方案為底坡i＝13％，斷麵6m ×6m城門洞形螺鏇式，洞身長310m。為閤理節約投資、節省工期，調壓井底闆混凝土澆築後，即作為壓力鋼管安裝運輸通道使用。安裝單位根據洞身變徑、螺鏇式特點，巧妙地運用卸車天錨、導嚮地錨配閤捲颺機、滑車繫統，順利完成安裝任務，解決瞭該工程壓力鋼管運輸難題。其經驗可為其他類似工程參攷。
