屋面的屋面構造中針對剛性屋頂防水易裂縫而發生滲漏的情況，采取了下列措施來削減裂縫。
In the roof structure of the roof for the rigid waterproof easy to crack and leakage of the situation, to take the following measures to reduce the cracks.
倒置屋面。用煤渣80mm、耕作層80mm、植被10mm’保護剛性屋頂防水層，可以有用地減緩溫度變形裂縫。
Upside down roofing. Cinder 80mm, tillage layer 80mm, vegetation protection 10mm’ rigid waterproof layer, can effectively reduce the temperature deformation cracks.
行使植被保護，可使屋頂防水層處于濕潤狀況（網站seo優化），防止混凝土收縮變形。
With the vegetation protection, the waterproof layer can be in a moist state, and prevent the concrete from being deformed.
行使預埋在結構層中的排水管孔作為變形預設縫，防止裂縫開展。
The use of pre buried in the structural layer of the drainage pipe hole as a deformation of the default seam to prevent the development of cracks.
在結構中貫徹以排為主及上下無壓差的思路（河南人事考試中心），設置了兩級排水體系及上下互通式排汽管路。
In the structure to carry out the main and up and down without pressure on the idea, set up two drainage system and the upper and lower exchange of steam pipeline.
復合排汽排水屋面的好處如下。
The advantages of composite drainage and drainage roof are as follows.
增長城市綠地，美化環境。
Increase urban green space, beautify the environment.
進步了房屋的保溫隔熱結果。
Improve the thermal insulation effect of housing.
有利于植被生長。
Conducive to vegetation growth.
便于維修。
Easy maintenance.
