天溝、檐溝是雨水最后流經的部位,被水流頻繁沖刷,容易積水,而且天溝、檐溝的結構較薄,變形較大,陰陽角多,基面不平整,因此應遵照多道設防、附加增強、節點密封的原則。首先在雨水口、陰陽角、整個溝底、側部作不同厚度要求的附加增強層。由于天溝、檐溝的基面轉角多,宜采用涂膜增強,在屋面與溝交接處宜采取空鋪方法,空鋪寬度不少于200mm,且涂膜收頭應用涂料多遍涂刷或密封材料密封。如天溝、檐溝采用卷材時,宜順溝鋪設,減少搭接縫,提高施工可靠率,并從溝底上翻至溝外檐頂部,卷材收頭應用水泥釘固定,并用密封材料封嚴。如果屋面層為剛性細石混凝土防水層時,在與檐溝、天溝交接處應留凹槽,填嵌密封材料。

Tiangou and eaves ditch are the last part of rainwater flow, which are frequently washed by water flow and easy to accumulate water. Moreover, the structure of Tiangou and eaves ditch is thin, the deformation is large, the Yin and Yang angles are many, and the base surface is not even. Therefore, the principles of multi-channel fortification, additional reinforcement and joint sealing should be followed. Firstly, additional reinforcement layers with different thickness requirements are made at rainwater outlet, Yinyang angle, whole ditch bottom and side. Because of the large turning angles of the base of the gutter and eaves, it is advisable to use film to strengthen the roof. The space-laying method should be adopted at the junction of the roof and gutter. The width of the space-laying is not less than 200 mm, and the end of the film should be coated with paint or sealed with sealing materials. For example, when coiled materials are used in Tiangou and eaves ditch, it is advisable to lay along ditches, reduce lap joints, improve construction reliability, and turn over from the bottom of ditches to the top of eaves. The end of coiled materials is fixed with cement nails and sealed with sealing materials. If the roof is a rigid fine stone concrete waterproof layer, the groove should be left at the junction with eaves and gutters, and the sealing material should be filled in.
