Underground bottom plate waterproof construction method
The invention relates to the field of underground engineering waterproofing, in particular to a waterproof construction method for an underground bottom plate. Comprising a spraying type pre-spraying anti-sticking waterproof coating and a double-layer composite non-asphalt-based polymer waterproof coiled material, and the spraying type pre-spraying anti-sticking waterproof coating is directly sprayed on the double-layer composite non-asphalt-based polymer waterproof coiled material which is laid on a cushion layer in an empty mode. The pre-spraying anti-sticking waterproof coating can be well bonded with the double-layer polymer waterproof coiled material, has flame retardance, prevents welding slag from damaging the waterproof coating, is high in peel strength with post-poured concrete, can form full adhesion with structural waterproof concrete, and achieves excellent waterproof and anti-water-channeling pre-spraying anti-sticking effects. The invention provides a construction method of an underground engineering bottom plate, which meets General Standard for Waterproof of Building and Municipal Engineering, and solves the problems that in the existing scheme, different types of materials are incompatible, hidden danger of water channeling exists in empty laying of a channel I and a channel II, the channel I is bonded with a cushion layer, and the waterproof effect is reduced and even water leaks due to the fact that the cushion layer is prone to cracking, hollowing, falling and the like.
本发明涉及地下工程防水领域，更具体的，涉及一种地下底板防水施工方法。包括喷涂型预喷反粘型防水涂料和双层复合非沥青基高分子防水卷材，其中喷涂型预喷反粘型防水涂料直接喷涂在空铺在垫层上的双层复合非沥青基高分子防水卷材，预喷反粘型防水涂料既可与双层高分子防水卷材粘接良好且有阻燃性，避免焊渣破坏防水涂层，又与后浇混凝土剥离强度高，可与结构防水混凝土形成满粘，达到防水及防窜水的优异预喷反粘效果。提供了一种满足《建筑与市政工程防水通用规范》的地下工程底板的施工工法，解决了现用方案中不同类型材料不相容、I道与II道空铺存在窜水隐患、I道与垫层粘接，因垫层易出现龟裂、空鼓、掉落等导致防水效果降低甚至漏水等问题。
