种植土土体与屋面防水的关系
[来源:来自网络] [作者:不详] [日期:22-08-03] [浏览次数:]

种植土土体与屋面防水的关系主要有以下几方面: 1)土体荷载对防水层的影响; 2)土体干湿度对防水层的影响; 3)土体酸碱度对防水层的影响; 4)土体的保温性能。 种植土堆的荷载越大,对结构屋面板的变形影响就越大;土体越厚,雨后土体的保水量就越大,干湿土质量差也越大,对结构变形就越不利。结构过量变形既有可能使结构板产生开裂,也有可能造成防水层的破坏。因此,屋面结构板既要保持足够的刚度,同时也要减少屋面结构的总质量,这对防水层是有利的。 种植屋面一方面要强调排水、另一方面也要强调蓄水保水,因为植物没水是不能生长的。因此,底部土体就可能永久性处于潮湿状态,也就意味着种植屋面防水层会长期处于潮湿或浸水状态,防水层的耐水性和耐霉变性、接缝可靠性也就成了选材的重要因素。 The relationship between planting soil and roof waterproofing is mainly in the following aspects: 1) the influence of soil load on waterproof layer; 2) the influence of dry and wet soil on the waterproof layer; 3) the influence of soil pH on the waterproof layer; 4) the thermal insulation performance of soil. The greater the load of planting soil pile, the greater the deformation of the roof slab. The thicker the soil is, the greater the water holding capacity of the soil will be, and the worse the dry and wet soil quality is, the more unfavorable the structural deformation will be. The excessive deformation of the structure can not only cause the cracking of the structural plate, but also may cause the damage of the waterproof layer. Therefore, the roof structure plate should not only maintain sufficient stiffness, but also reduce the total quality of the roof structure, which is beneficial to the waterproof layer. On the one hand, planting roofs should emphasize drainage, and on the other hand, water preservation should be emphasized because plants can not grow without water. Therefore, the bottom soil may be permanently wet, which means that the roof waterproofing layer will remain wet or soaked for a long time. The water resistance and mould resistance and joint reliability of the waterproof layer will also become an important factor for material
