Pool construction conditions:

室内景园中的水池，一种是砌筑于地面以下，另一种是砌筑于楼层板之上。

The pool in the indoor garden is built below the ground and above the floor slab.

(1)砌筑于地面以下的水池，在室内地面未做好之前就应安排好供排水管道，排水管应接通在室外下水道上。

(1) For the pool built below the ground, the water supply and drainage pipes should be arranged before the indoor ground is completed, and the drainage pipes should be connected to the outdoor sewer.

(2)砌筑于楼面板上的水池，一般不易太深，而且往往将水池边作成阶梯式。其供排管道可藏于其中，并要巧妙地安排，使管道在不影响美观的前提下通向室外。

(2) The pool built on the floor is generally not too deep, and the pool edge is often made into a ladder type. The supply and discharge pipes can be hidden in them, and should be ingeniously arranged so that the pipes can lead to the outside without affecting the appearance.

(二)水池施工要点

（2） Key points of pool construction

1、水池的砌筑要求：

1. Masonry requirements for pool:

室内水池的砌筑，通常用混凝土浇筑，池边与池底浇筑为一整本，如水了深度大于500mm，应用钢筋混凝土砌筑。在地面以下砌筑水池时，水了下的土基部分应做密实。其混凝土厚度可为100--150mm。在楼板面上做水池时，水池的混凝土厚度为100mm左右，水池的深度不要大于400mm。

The masonry of indoor pool is usually poured with concrete. The pool side and bottom are poured as a whole. If the water depth is more than 500mm, the reinforced concrete shall be used for masonry. When building a pool below the ground, the underwater soil foundation shall be compacted. The concrete thickness can be 100-150mm. When making a pool on the floor, the concrete thickness of the pool is about 100mm, and the depth of the pool is not more than 400mm.

2、防渗防漏的处理方法：

2. Treatment methods for seepage prevention and leakage prevention:

(1)水池砌筑时的防漏方法：当水池基体砌筑完毕，并浇水保养24h后便可进行防漏施工。如果防水要求很高，也可在砌筑混凝土水池基体时，就在混凝土中加入防水剂。用于混凝土的防水材料通常为防水粉和避水剂。水池基体砌筑完后的防漏方法是采用防水砂浆抹面，抹面要分两次进行，每次抹面层厚10mm左右，待第二次防水砂浆初凝时，要将其面压实抹光。

(1) Leakage prevention method during pool masonry: after the pool base is built and watered for 24h, leakage prevention construction can be carried out. If the waterproof requirement is very high, the waterproof agent can also be added to the concrete when building the concrete pool base. The waterproof materials used for concrete are usually waterproof powder and water repellent. The leakage prevention method after the foundation of the pool is to use waterproof mortar plastering. The plastering shall be carried out in two times. The thickness of each plastering layer is about 10mm. When the second waterproof mortar is initially set, its surface shall be compacted and trowelled.

(2)防水混凝土的配制：在拌合防水混凝土时，先将按所需水泥重量百分之三左右的避水剂，倒入塑料桶内，再向桶加入水，边加水边搅拌，直至总量等于所需的水灰比用水量为止。然后用此浆水搅合水泥砂石。其防水混凝土的配合比为水泥:中砂:细石子=1:2:4。

(2) Preparation of waterproof concrete: when mixing waterproof concrete, pour about 3% of the required cement weight into the plastic bucket, then add water to the bucket, and mix while adding water until the total amount is equal to the required water cement ratio. Then use this grout to mix the cement sand and gravel. The mix ratio of waterproof concrete is cement: medium sand: fine stone=1:2:4.

(3)防水抹面层砂浆的配制：防水抹面砂浆配制，同样是先将避水剂与水先拌合，避水剂的用量为所需水泥量的百分之五左右。然后将拌合好的避水浆液掺入水泥和砂内搅拌，水泥:中砂=1:2，水泥标号为425号。

(3) Preparation of waterproof plastering mortar: the waterproof plastering mortar is also prepared by mixing the water repellent with water first. The amount of water repellent is about 5% of the required cement amount. Then mix the mixed water repellent grout into cement and sand, cement: medium sand=1:2, cement grade is 425.

应当注意的是，不是所有的防水剂、避水剂都能作为水池的混凝土基体和内面层砂浆的防水材料。因为有些牌号的防水剂，只能补漏而不能大面积承重。所以采用防水剂要了解清楚后再使用。

It should be noted that not all waterproof agents and water repellents can be used as waterproof materials for the concrete base of the pool and the mortar of the inner surface course. Because some brands of waterproof agent can only repair the leakage and cannot bear large area of load. Therefore, the waterproof agent shall be used after clear understanding.

(4)面层的防水涂层：为了使防水防漏更可靠，在水池基本和抹面防水砂浆完成后，再在水池内表面涂刷一层防水涂料，然后再进行饰面施工。通常采用的防水涂料有：“确保时”防水涂料、氯丁-1防水涂料、聚氨脂涂膜防水涂料、JM-811防水涂料。饰面的嵌缝防水材料有：塑料油膏、聚氯乙烯胶泥、水乳丙烯酸密封膏等。

(4) Waterproof coating of surface course: in order to make waterproof and leak proof more reliable, after the completion of the basic pool and plastering waterproof mortar, a layer of waterproof coating shall be applied on the inner surface of the pool, and then the finishing construction shall be carried out. The commonly used waterproof coatings are: "ensure time" waterproof coating, neoprene 1 waterproof coating, polyurethane film waterproof coating, JM-811 waterproof coating. The caulking waterproof materials for the facing are: plastic ointment, PVC mastic, water emulsion acrylic sealant, etc.

3、水池的饰面施工：

3. Finishing construction of pool:

水池的饰面关键在于水池边岸的施工。边岸饰面时应做工精致，不可粗制滥造马虎施工。当用小卵石贴砌池岸时，卵石应经过筛选，大小基本一致。贴砌矿石用白水泥砂浆铺底，然后把卵石洒铺在白水浆层上，再拍压卵石，使其镶嵌在白水泥砂浆中，但要露出卵石的光滑表面，卵石的布置要均匀。

The key to the finishing of the pool is the construction of the pool bank. The decoration of the side and bank shall be exquisite and shall not be constructed carelessly. When small pebbles are used to stick to the pool bank, the pebbles shall be screened and basically of the same size. Pave the ore with white cement mortar, then spread the pebbles on the white water slurry layer, and then pat and press the pebbles to inlay them in the white cement mortar, but the smooth surface of the pebbles shall be exposed, and the pebbles shall be evenly arranged.
 

大理石矿块嵌镶池岸时，往往要根据大理石的天然色彩和大小块来安排嵌铺，色彩与大小块的布置要均匀和协调。嵌铺方式又分为无缝铺和留缝铺两种。无缝铺就是在大理石碎块之间用白水尼填满缝隙，留缝铺就是大理石碎块之间不完全填满白水泥，使大理石碎块幝面上有凹下的纹路。但这两种方式嵌贴时，其大面一定要平整。

When the marble ore block is inlaid on the pool bank, the inlay is usually arranged according to the natural color and size of the marble, and the color and size of the block should be arranged evenly and harmoniously. The embedded paving method is divided into seamless paving and seam paving. Seamless paving is to fill the gap between the marble fragments with white water, while seam paving is to fill the gap between the marble fragments with white cement incompletely, so that there are concave lines on the surface of the marble fragments. However, when these two methods are applied, the large surface must be flat.

其它瓷砖饰面、大理石整板饰面、花岗岩整板饰面同普通地面施工。但在镶贴时可用防水砂浆来铺贴施工。

Other ceramic tile finishes, marble whole board finishes and granite whole board finishes are the same as those of ordinary floors. However, waterproof mortar can be used for paving construction.

4、喷水池、瀑布的回水方式：

4. Water return mode of fountain and waterfall:

喷水池、小瀑布的回水方式大都采用自循环式。即采用一个水泵，从池内吸水，并将水供至瀑布的源头处，瀑布水再回落至水池内，周而复始地循环。如果池内水变少时，可打开补水阀门，将新鲜自来水加入池内。

The backwater of the fountain and small waterfall is mostly self circulating. That is to say, a water pump is used to absorb water from the pool and supply the water to the source of the waterfall, and then the waterfall water falls back into the pool and circulates again and again. If there is less water in the pool, open the make-up valve and add fresh tap water into the pool.

当喷水池需在同一处位置，进行喷水和回水时，可用套管式方法进行，即将喷水装在回水内，两者既装在一起，但又互不影响。回水池可安置在小喷泉下，也可将其安排在室外，并可将几个小喷泉共用一个供水回水系统。

When the spray tank needs to be at the same location for water spraying and backwater, the casing method can be used, that is, the water spraying is installed in the backwater, both of which are installed together, but do not affect each other. The return pool can be placed under a small fountain or arranged outdoors, and several small fountains can share a water supply and return system.
