地下室防水的方案有哪些?

更新時間:2016-10-21 15:56:17點擊次數:1433次字號:T|T
外防外貼防水法,即在底板墊層上鋪設卷材防水層,并在圍護結構墻體施工完成后,再將立面卷材(防水層)直接鋪貼在圍護結構的外墻面,然后采取保護措施的地下室防水施工方法。這款地下室防水施工方案其優點是隨時間的推移,圍護結構墻體的混凝土將會逐漸干燥,能有效防止室內潮濕,但當基坑采取大開挖和板樁支護時,則需采取措施,以解決水平支撐部位影響地下室堵漏的問題。

 2地下室防水的方案——離壁式襯砌防水施工
該地下室防水施工方案除在圍護結構的混凝土墻體及其內表面采取防水措施外,為達到地下室堵漏施工要求,再在主墻內側增設1道離壁式內墻。該地下室防水設計方案雖屬多道設防并有利于排水,但存在造價高,圍護結構墻體不易得到充分干燥,以及較難確保柱、墻混凝土接縫部位的水密性等問題。

 3地下室防水的方案——外防內貼法施工

 外防內貼法是在底板墊層上先將保護墻全部砌完,再將卷材(防水層)鋪貼在保護墻和底板墊層上,待地下室防水層全部做完,最后澆筑圍護結構混凝土。這款地下室防水施工方案是在施工環境條件受到限制,難以實施外防外貼法而不得不采用的一種地下室堵漏施工方法。

 以上是小編對地下室防水的做法是什么有哪些方案呢的介紹,我們對地下室防水的做法是什么有哪些方案呢已經有了一個大概的了解,希望上面小編的介紹可以幫助到大家。
