Description

地下室防水构造及其施工方法Basement waterproof structure and its construction method

技术领域technical field

本发明属于建筑防水领域,尤其涉及一种地下室防水构造及其施工方法。The invention belongs to the field of building waterproofing, in particular to a basement waterproofing structure and a construction method thereof.

背景技术Background technique

随着建筑业的不断发展和城市化进程的加快,地下室的种类和数量不断加大,对地下室防水要求越来越高,地下室防水工作做不好将严重影响到地下室的正常使用,而且返修费用也非常昂贵。当前地下室防水的传统做法是在混凝土基层上铺设防水卷材或涂刷防水涂料,尽管各种防水材料的种类和质量在不断改进和提高,但由于混凝土热胀冷缩产生的裂纹、防水材料搭接处的处理不当和地下水压高低不同的影响,单一的刚性自防水和柔性防水结合的方式在防水要求较高的场合难以达到防水要求,不但难以竣工验收,也给返修带来困难。因此,地下室防水要根据地下室实际情况做到防排结合、因地制宜的原则,既要有合理的防水构造层次,也要把握好施工质量关,使地下室防水达到设计使用年限。With the continuous development of the construction industry and the acceleration of urbanization, the types and numbers of basements are increasing, and the requirements for basement waterproofing are getting higher and higher. If the basement waterproofing work is not done well, it will seriously affect the normal use of the basement, and the repair cost Also very expensive. The current traditional method of basement waterproofing is to lay waterproof membranes or paint waterproof coatings on the concrete base. Influenced by improper handling of joints and different levels of groundwater pressure, a single combination of rigid self-waterproofing and flexible waterproofing is difficult to meet the waterproofing requirements in places with high waterproofing requirements. It is not only difficult for completion acceptance, but also brings difficulties for repairs. Therefore, basement waterproofing should be based on the actual situation of the basement to achieve the principle of combining anti-drainage and adapting measures to local conditions. It must not only have a reasonable waterproof structure level, but also grasp the construction quality, so that the basement waterproof can reach the design service life.

针对目前部分地下室防水构造层次不够合理和防水等级较低的弊端,发明人设计一种地下室防水构造,从地下室种植顶板、侧墙和底板三个方面进行全面防护,其中:种植顶板包括由里到外的结构自防水混凝土顶板、聚合物防水浆料、防水卷材、蓄排水板、无纺布、种植土和植被层;侧墙包括由里到外的结构自防水混凝土侧墙、聚合物防水浆料、防水卷材、蓄排水板和回填土;底板包括由外到里的结构自防水混凝土底板、防水卷材、细石混凝土垫层和回填土。据此,发明人还建立了相应施工方法。与现有技术相比,本发明具有以下突出优势:Aiming at the shortcomings of unreasonable levels and low waterproof level of some basement waterproof structures, the inventor designed a basement waterproof structure, which provides comprehensive protection from three aspects: the planting roof, side walls and bottom plate of the basement, wherein: the planting roof includes from inside to External structural self-waterproof concrete roof, polymer waterproof slurry, waterproof membrane, storage and drainage board, non-woven fabric, planting soil and vegetation layer; side walls include structural self-waterproof concrete side walls from inside to outside, polymer waterproof Slurry, waterproof membrane, storage and drainage board and backfill soil; the base plate includes a structural self-waterproof concrete base plate from the outside to the inside, waterproof membrane material, fine stone concrete cushion and backfill soil. Accordingly, the inventor has also established a corresponding construction method. Compared with the prior art, the present invention has the following outstanding advantages:

1)结构自防水混凝土顶板采取抛丸或随浇随抹平方式施工,保证了基层强度,使防水层置于坚固结构之上;作为防水卷材粘结剂的聚合物防水浆料,具有良好的弹性、低收缩率,而且与基层混凝土粘结牢固,不脱落、不开裂,同时自身还具有优异的防水性能,能封闭结构微裂缝;地下室种植顶板构造中采用了蓄排水板和虹吸排水,既能保留适量水分满足植被需求,又可通过虹吸作用将多余水分排掉,保证植被根系不被腐化。1) The structural self-waterproof concrete top plate is constructed by shot blasting or pouring and troweling, which ensures the strength of the base layer and places the waterproof layer on a solid structure; the polymer waterproof slurry used as a waterproof membrane binder has good It has excellent elasticity and low shrinkage, and is firmly bonded to the base concrete without falling off or cracking. At the same time, it also has excellent waterproof performance and can seal micro-cracks in the structure; the basement planting roof structure adopts storage and drainage boards and siphon drainage. It can not only retain an appropriate amount of water to meet the needs of vegetation, but also drain excess water through siphon action to ensure that the root system of vegetation is not corroded.

2)地下室侧墙构造中,蓄排水板在防水层中起到软保护作用,蓄排水板凸点面朝外,贴上无纺布后形成滤水和透水作用,符合“排防结合”的防水原则;而且蓄排水板的软保护属永久性防水保护层,相对于聚苯板,造价合理,更环保节能,同时有利于减少地下室内结露水。2) In the structure of the side wall of the basement, the storage and drainage board plays a soft protective role in the waterproof layer. The convex point of the storage and drainage board faces outwards, and the non-woven fabric is pasted to form water filtration and water permeability, which is in line with the "combination of drainage and defense" Waterproof principle; moreover, the soft protection of the storage and drainage board is a permanent waterproof protective layer. Compared with polystyrene boards, the cost is reasonable, more environmentally friendly and energy-saving, and it is also conducive to reducing dew condensation in the basement.

3)地下室底板构造中防水卷材施工采用预铺反粘方法,防水层与底板防水混凝土水化热反应形成皮肤式防水层,彻底解决了窜水渗漏风险;同时可有效避免传统做法(防水层粘结于垫层上)因回填土下垮,造成垫层下沉开裂从而拉裂和破坏防水层,形成真正意义上的“正面防水”。3) The waterproof membrane construction in the basement floor structure adopts the pre-paved anti-adhesive method, and the waterproof layer reacts with the hydration heat of the floor waterproof concrete to form a skin-type waterproof layer, which completely solves the risk of water leakage; at the same time, it can effectively avoid the traditional method (waterproof Layer bonded to the cushion) due to the collapse of the backfill, the cushion sinks and cracks, thereby tearing and destroying the waterproof layer, forming a true "frontal waterproof".

总之,本发明的地下室防水构造由地下室种植顶板、侧墙和底板共同形成对整个地下室的“全外包”皮肤式防水,而且施工简单易行,综合造价低、防水性能好、性价比高,可满足建筑市场对综合性能理想的地下室防水的需求,适合广泛应用于地下室和其他地下建筑的防水。In a word, the basement waterproof structure of the present invention is composed of the basement planting roof, side walls and bottom plate to form a "full outsourcing" skin-type waterproofing for the entire basement, and the construction is simple and easy, with low overall cost, good waterproof performance, and high cost performance. The construction market needs basement waterproofing with ideal comprehensive performance, which is suitable for waterproofing of basements and other underground buildings.
