一、穿過屋頂防水層的管道、預埋件、設備基礎等均應在屋頂防水層施工前埋設和安裝完畢;
First, through the pipeline, the waterproof layer and equipment foundation shall be embedded in the construction of waterproof layer and buried before installation;
二、下層排水坡度應符合設計要求;
Two, the grass roots drainage slope should meet the design requirements;
三、管道與結構之前的縫隙應用細石混凝土或聚合物屋頂防水砂漿堵嚴;
Three, the gap between the pipe and the structure before the application of fine stone concrete or polymer waterproof mortar blocking;
四、對當天施工的基面進行清理,下層要堅固、無酥松、起砂與凹凸不平,要求基面干凈,可以潮濕,但不得有明水、油污、雜物和其他可能破壞屋頂防水層的材料,下層外觀顯明凹凸不平時宜先用水泥砂漿找平;
Four, to clean up the base day construction, basic to strong, crisp, no sand and uneven surface, require clean, can be wet, but can not have water, oil, and other debris may destroy the waterproof layer material, the surface of the base is obviously uneven advisable to use cement mortar;
五、雨水口、施工縫、陰陽轉角、管根、設備基礎等必要進行局部增強處理的,應用手刮式液體橡膠屋頂防水涂料浸涂70-80g/m2短纖維針刺無紡布粘貼。
Five, rain mouth, construction joints, and the Yin and Yang corner, Guan Gen, equipment foundation, etc. need to be locally reinforced treatment, the application of hand scraping liquid rubber waterproof coating dip coating 70-80g/m2 short fiber.
步驟Step;
雙組分(噴涂型)其A組分(液料)與B組分(液料)是由專用噴涂速凝設備,按設定好的比例、壓力等進行噴涂作業不銹鋼閘閥,3-5s固結成膜。適用于暗挖隧道拱頂等未便于涂抹施工的部位及大面積屋頂防水施工。
Two component (spray type) of its A component (liquid material) and B component (liquid material) is by special spray quick setting equipment, according to set a good proportion, pressure and other spraying operations, 3-5s consolidation into a film. Applicable to the roof of the tunnel excavation is not easy to smear the construction site and the large area of waterproof construction.
在大面積噴涂前應等到附加層悉數成膜后進行,先檢查噴涂機的完備性、噴涂機的噴槍是否清潔以及質料傳輸管、濾網、閥門,并檢查噴涂機是否可以正常工作。噴涂作業應分區施工并預先做好遮擋工作。調整好噴嘴與基面距離、角度及噴涂設備壓力以求達到噴涂后的材料外觀夾帶,不露底且薄厚均勻。
In the large area before spraying should wait until after the film all the additional layer, first check the integrity of the spraying machine, spraying machine gun is clean as well as the raw material transmission tube, filter, valve, and check whether the spraying machine can work normally. Spray work should be partition construction and pre do block work. Adjust the distance and angle of the nozzle and the base pressure and spraying equipment in order to achieve the material surface entrainment after spraying, and do not show uniform thickness.
