Construction Technology of Waterproof Engineering
在结构混凝土浇筑完成之后，需要对混凝土的基面进行处理，主要是在顶板上使用木抹子，这样才能对水分进行吸收，对于凹凸不平或者蜂窝、裂缝等现象，需要保证清洁性，不出现渗水现象。在涂料施工之前，采用1：2．5的水泥浆进行倒角处理。基层验收合格后，需要在阴阳角或者施工缝中涂抹加强层，其厚度在1 mn'l左右，在完成防水加强层的涂抹之后，涂抹增强层，然后再涂抹防水层。在大面积的涂抹防水施工中，防水层需要采用多道涂刷，施工时要保证涂刷方向的垂直性，须到涂抹固化之后，再进行下一道涂抹工序。顶板采用粘土以及灰土进行回填，其回填的厚度要小于600mm，其中在回填土时不能含有石块、碎石等M】。人工夯实的每层厚度需要大于250 mm，机械夯实的每层厚度需要大于300 mm，在夯实时候要避免对防水层产生损坏。在对其进行回填时，厚度需要保持在500mm以下，回填施工采取机械回填的方式。
After the completion of concrete pouring, it is necessary to treat the base of concrete, mainly using wooden plaster on the roof, so as to absorb water. For uneven or honeycomb, cracks and other phenomena, it is necessary to ensure cleanliness without seepage. Before coating construction, 1:2.5 cement slurry is used for chamfering treatment. After passing the acceptance of the basic level, it is necessary to apply the strengthening layer in the Yinyang angle or construction joints. Its thickness is about 1 mn'l. tuoshuiji.75ix.com   tuoshuijiw.75ix.com   wushuizhili.75ix.com

In large-scale waterproofing construction, the waterproofing layer needs to be multi-channel brushing, to ensure the perpendicularity of the direction of the brushing, it must be solidified after the painting, and then the next painting process. The roof is backfilled with clay and lime soil, and the backfill thickness is less than 600 mm. The backfill should not contain stones, gravel and other M uuuuuuuuuuuu The thickness of each layer of manual tamping should be greater than 250 mm, and the thickness of each layer of mechanical tamping should be greater than 300 mm. Damage to waterproof layer should be avoided in real-time tamping. When backfilling, the thickness should be kept below 500 mm, and mechanical backfilling should be adopted in backfilling construction.
