Description
本发明属于构造防水技术领域，具体涉及一种大放脚底板与侧墙不同防水材料的搭接方法。The invention belongs to the technical field of structural waterproofing, and in particular relates to a method for lap jointing a large foot soleplate and a side wall with different waterproof materials.
地下工程由于深埋在地下，时刻受到地下水的渗透作用，如防水问题处理不好，导致地下水渗透到建筑物内部或者建筑物体内，将会带来一系列问题：如影响人员的工作和生活；加快建筑物被腐蚀的速度，缩短使用寿命。Because underground engineering is deeply buried in the ground, it is always subject to the infiltration of groundwater. If the waterproof problem is not handled properly, the groundwater will infiltrate into the interior of the building or inside the building, which will bring a series of problems: such as affecting the work and life of people; Accelerates the rate at which buildings are corroded and shortens their service life.
根据国家规范《地下工程防水技术规范》GB50108-2008中描述对于单建式地下工程应采用全封闭、部分封闭的防排水设计，防水材料应从结构底板垫层铺设至顶板基面，并应在外围形成封闭的防水层。卷材接槎的搭接长度，高聚物改性沥青类卷材应为150mm，合成高分子类卷材应为100mm；当使用两层卷材时，卷材接缝应错开，上层卷材应盖过下层卷材。According to the national standard "Technical Specification for Waterproofing of Underground Engineering" GB50108-2008, a fully enclosed and partially enclosed waterproof and drainage design should be adopted for single-built underground projects. Forms a closed waterproof layer. The lap length of the coils should be 150mm for high polymer modified asphalt coils and 100mm for synthetic polymer coils; when two layers of coils are used, the joints of the coils should be staggered and the upper layer of coils Should cover the underlying coil.
然而对于大放脚底板防水卷材与侧墙防水涂料的搭接，传统的方法还是存在如下缺陷：①底板防水层的预留搭接部位由于后期的施工污染或者环境气候的影响，导致无法与侧墙防水层搭接形成封闭防水层；②底板防水层的预留搭接部位未做临时保护而被破坏，导致无法与侧墙防水层搭接形成封闭防水层。However, the traditional method still has the following defects for the lap joint of the bottom plate waterproofing membrane and the side wall waterproof coating: 1. The reserved overlapping part of the bottom plate waterproof layer cannot be connected to the joint due to the later construction pollution or the influence of the environmental climate. The side wall waterproof layer is overlapped to form a closed waterproof layer; ② the reserved overlapped part of the bottom plate waterproof layer is damaged without temporary protection, resulting in the inability to overlap with the side wall waterproof layer to form a closed waterproof layer.
为了提升大放脚底板与侧墙处的搭接部位的防水性能，专利中公开的方法有：如中国专利CN109537636A适用于大放脚的底板防水卷材与侧墙防水涂料的交圈方法，其包括：A、在砖胎膜顶部的底板防水卷材预留甩头；B、在与底板防水卷材的端部相距的预设距离处临时打多个水泥钉固定；C、在甩头部位的底板防水卷材的表面铺贴隔离膜；D、利用低标号水泥砂浆在隔离膜上砌筑灰砂砖临时保护；E、侧墙防水涂料施工至交圈部位时，拆除临时保护的灰砂砖和隔离膜，割除水泥钉；F、将水性环氧封底涂料辊涂于底板防水卷材的甩头部位表面；G、将侧墙防水涂料直接延伸施工至交圈部位与底板防水卷材交圈搭接。In order to improve the waterproof performance of the lap joint between the bottom plate and the side wall of the large foot, the methods disclosed in the patent are: such as the Chinese patent CN109537636A, which is suitable for the cross-loop method of the bottom waterproof membrane of the large foot and the side wall waterproof coating. Including: A. Reserve the head shake of the bottom plate waterproofing membrane on the top of the brick tire membrane; B. Temporarily hit a plurality of cement nails at a preset distance from the end of the bottom plate waterproofing membrane to fix; C. Place an isolation film on the surface of the bottom floor waterproofing membrane; D. Use low-grade cement mortar to build lime-sand bricks on the isolation film for temporary protection; E. When the side wall waterproof coating is applied to the intersection, remove the temporarily protected lime-sand Bricks and isolation film, cut off the cement nails; F. Roll the water-based epoxy primer coating on the surface of the head-flushing part of the bottom plate waterproofing membrane; G. Extend the side wall waterproofing coating directly to the intersection part and the bottom plate waterproofing membrane. Circle lap.
上述方法虽然能一定程度上提升大放脚与侧墙搭接处的防水，但还是存在以下不足：1)保护墙和基础底板的不均匀沉降导致防水材料搭接部位的破坏解决不了，还是会发生渗漏水的情况；2)用低标号砂浆砌筑临时保护墙还需用钉子固定卷材和再 次铺贴隔离层；3)虽然在甩头部位的底板防水卷材再次铺贴隔离层，但还是避免不了现场污染搭接部位的问题，达不到预期的形成封闭防水层的问题。Although the above method can improve the waterproof of the lap joint between the large foot and the side wall to a certain extent, it still has the following shortcomings: 1) The uneven settlement of the protective wall and the base plate leads to the damage of the lap joint of the waterproof material. In case of water leakage; 2) It is necessary to use nails to fix the coil and re-apply the isolation layer to build the temporary protective wall with low-grade mortar; 3) Although the bottom waterproofing membrane at the head-shake part is re-applied with the isolation layer However, the problem of on-site contamination of overlapping parts cannot be avoided, and the expected problem of forming a closed waterproof layer cannot be achieved.
