室内立管同层排水是一种新颖的设计和施工安装工艺，是在钢筋混凝土楼面完工之后，将体型扁薄的横排地漏和管网，在找平层内直接接入立管。坐便器采用后排水，或将分体水箱隐藏在管廊隔板内。为方便管网检修，在沐浴间内设置有防水的检修门。主人卫生间内，为浴缸排水管网水封有足够合理的安排，宜将浴缸底部升高至找平层以上。找平层的高度仅比传统楼面提高55mm。既解决了传统穿楼排水管网滴漏、清通影响邻居环境卫生问题，又比采用沉箱埋管节约投资。更换设备及管网维修方面与沉箱埋管方式比较，前者轻便，后者费时费力。发展同层排水其难度不在于技术，而是传统观念。2003年的《建筑给水排水设计规范》规定：地漏的水封深度，是根据国外规范条文制定的。50mm水封深度是确定重力流排水系统的通气管管径和排水管管径的基础。某些地区试图加设吸气阀，降低水封深度的做法是不妥的。其一吸气阀仅平衡负压，而不能消除正压波动。其二吸气阀阀瓣老化，功能丧失后引起室内环境污染。其三地漏减小水封深度势必减小水封水容积，容易蒸发干涸。吸气阀能消除负压，至虹吸抽失量近于零。正压无需靠阀件取消除，而是靠“倍增”结构原理，利用管网内能去推动水封增幅。吸气阀阀片老化问题，是技术突破中最为关键的部分，采用耐磨、防油、致密硅橡胶加抗老化剂等，提高技术性能，老化期达8~10年，更换势必家中换灯泡还容易。所以说，钟罩式地漏无论从静态或动态方面比较，都不存在优越性。因为后者设计是一低水封为指导思想，特意用少蒸发损耗和高回部的方式取得高性能，将高质量吸气阀设在隐蔽处，更能保证其独特效果。地漏采取水封保护，概念应予更新。

Floor drain and the suction valve safety issues Indoor riser the same floor drainage is a novel design and construction of the installation process, after the completion of the reinforced concrete floor, the body flat thin horizontal drain and pipe network, direct access to the riser in the leveling layer. Toilet after drainage, or split tank hidden in the partition of the pipe gallery. For the convenience of the pipe network maintenance, waterproof access door set in the shower rooms. The master bathroom, bathtub drainage network water seal, adequate and reasonable arrangements, should be increased to the bathtub at the bottom of the leveling layer above. The height of the leveling layer than the traditional floor only improve the 55mm. Resolve the drip of the traditional wear of floor drainage network, clear impact neighbors environmental health issues surpasses the caisson pipe saving investment. Replacement of equipment and pipe network maintenance and caisson pipe way, the former light, which is time-consuming. The development of the same layer of drainage of its difficulty does not lie in technology, but the traditional concept. Provisions of the 2003 "Water and Drainage Design specification: the depth of the water seal of floor drain, is developed in accordance with the provisions of the foreign standards. 50mm seal depth is the basis of the diameter of the ventilator to determine the gravity flow drainage system and drain pipe. Certain areas trying to installing the suction valve to reduce the seal depth approach is inappropriate. The first suction valve only to balance the negative pressure, but can not eliminate the positive pressure fluctuations. The second suction valve valve aging, loss of function caused by indoor environmental pollution. Third, omitted to reduce the water seal depth is bound to reduce the water seal water volume, easy to evaporate dry. Suction valve can eliminate the negative pressure to siphon pumping loss close to zero. Positive pressure do not need to rely on valves canceled in addition to, but by the principle of "double" structure, the use of the water seal to promote an increase in the pipe network. Valves of suction valve problem of aging is the most critical part of the technological breakthroughs of wear resistant, oil resistant, dense silicone rubber, anti-aging agent, to improve the technical performance of the aging period of 8 to 10 years, replacement is bound to change a light bulb at home also easy. So, the bell-type floor drain in terms of static or dynamic does not exist in the superiority of. Because the latter design is a low-water seal as the guiding ideology, specifically to use less the evaporation loss and Huibu of the obtained high-performance, high-quality suction valve located in the shelter, can guarantee its unique effect. The floor drain to take water seal protection, the concept should be updated.
