伊朗TALEGHAN水利枢纽厂房封闭帷幕灌浆施工

Closed Curtain Grouting Construction of Powerhouse of TALEGHAN Water Control Project in Iran

摘要:

伊朗TALEGHAN水利枢纽工程发电厂房位于库区左岸山体内，需要承受80 m深水头高度的渗透压力，对地下厂房的防渗要求极高，施工技术难度大。根据这一特点有针对性地对弱透水岩层采用了湿磨水泥进行灌注，取得了较好的灌浆效果。重点介绍了地下厂房四周封闭帷幕灌浆的施工方法，为类似工程的防渗灌浆施工提供了可借鉴的经验。

Abstract:

Powerhouse of TALEGHAN water control project of Iran is located in the mountains on the left bank of reservoir area. With high seepage pressure of 80m water head height, the construction was difficult because of extremely high requirements for seepage control on underground powerhouse. On this basis, targeted wet grinding cement grouting was applied in weak permeable layer with good effects. The paper mainly introduces the construction method of enclosed curtain grouting for underground powerhouse, which can be reference to the similar projects.
