In reinforced concrete water retaining/excluding structures, a potential source of leakage or water ingress is the construction joint, and that is why water bars (also called water stops) must be provided whether there is a risk of groundwater or not. Water bars are barriers that are provided in the construction joint of concrete structures to prevent the egress or ingress of water into the structure.
在钢筋混凝土挡水/摒除结构中，渗漏或进水的潜在开首是施工接缝，这即是为什么岂论是否存在地下水风险，都必须缔造止水条（也称为止水带）。止水条是在混凝土结构的施工缝中缔造的樊篱，用于驻防水浸透或参加结构。
Constructions joints are usually created due to the difficulty in casting multiple members of a water retaining structure on the same day (such as casting tank base and walls on the same day). Apart from providing reinforcements to limit crack width to 0.2mm and providing water stops, good workmanship is important because inadequacies such as honeycombs, poor compaction, foreign materials in the concrete, poor installation of water bars, etc can compromise the entire effort.
施工缝的产生频频是由于很难在团结天浇筑挡水结构的多个构件（如在团结天浇筑水箱底座和墙壁）。除了提供钢筋以将症结宽度物化在0.2mm和提供止水带外，致密的施工工艺也很紧迫，因为蜂窝、压实不良、混凝土中的异物、止水条安装不妥等不及之处都会影响所有工程。
In the construction of tanks and swimming pools, the construction joint between the walls and the base is facilitated with the use of kickers, which are the best cast monolithically with the base slab. Kickers should be at least 150 mm thick and should incorporate water bars. Kickerless construction can be carried out by some contractors, but that will increase the risk of water penetration. However, hydrophilic (water-swellable) water bars can be used when there is no kicker, and this has performed well in construction from experience. Accurate positioning of the PVC water bar is important in this case.
在斥地储池塘和游池塘时，墙壁和底座之间的施工缝可通过使用踢脚板来齐备，踢脚板最佳与底座板举座浇筑。踢脚板的厚度至少应为 150 毫米，并应包含止水条。有些承包商不错接纳无踢脚的施工圭臬，但这会增多渗水的风险。不外，在莫得踢脚线的情况下，不错使用亲水（遇水推广）止水带，把柄陶冶，这种止水带在施工中证实致密。 在这种情况下，PVC 防水条的准笃定位十分紧迫。

Preformed strips are made of impermeable but durable materials which are embedded in the concrete during concreting. Typically they are installed at the construction joints to provide a watertight seal during movements within the joint. These are popularly called water bars. Water bars are usually made of flexible PVC material or steel, with the former being more popular. However, care must be taken during placement to ensure that the flexible PVC water bar does not collapse during the placement of concrete. This is the advantage that a steel water bar has over a PVC water bar. Steel water bar is usually made of 1.5 mm thick black steel or stainless steel, which by virtue of its stiffness remains permanently in place during concreting.
预制条带由不透水但耐用的材料制成，在浇筑混凝土时镶嵌混凝土中。频频，它们安装在施工接缝处，以便在接缝内迁顷刻提供防水密封。这些频频被称为止水条。止水条频频由柔性PVC材料或钢制成，前者更受迎接。然而，在扬弃经由中必须堤防，以确保柔性PVC止水条在混凝土扬弃经由中不会歪倒。这是钢制止水条联系于PVC止水条的上风。钢制止水条频频由1.5毫米厚的黑钢或不锈钢制成，由于其刚度，在混凝土浇筑经由中永久保握原位。
2. Hydrophilic/Swellable Water Stops 亲水/推广止水
These water stops are produced with hydrophilic material which swells and develops a sealing pressure when it comes in contact with water. They are usually bonded or nailed to the old concrete before the first pour of the new concrete and their use is limited to joints where the movement is low. Swellable water bars are popular in kickerless construction.
这些止水块由亲水材料制成，当它与水构兵时会推广并产生密封压力。它们频频在新混凝土第一次浇筑之前粘合或钉在旧混凝土上，它们的使用仅限于变形量较低的接缝。推广止水带在无踢脚板结构中很受迎接。
For swellable water bars to be effective, the strip must lie flush with the substrate (hardened concrete). Appropriate care must also be taken at the joints to ensure that there will be no room for water penetration.
为了使可推广的水条灵验，条带必须与基材（硬化混凝土）皆平。还必须在接缝处接纳符合的照拂秩序，以确保莫得渗水的空间。

博彩关键词
The water-stopping action of this material is from salt crystallization in the presence of water within the pores and capillaries of the concrete. They are prepared by mixing cement, fillers, and chemicals on site as slurry, which is then applied on the surface of the old concrete before pouring the new concrete. They are not suitable for use in expansion joints but in construction joints only.
这种材料的止水作用是在混凝土的孔隙和毛细管内存在水的情况下盐结晶。 它们是通过在现场搀杂水泥、填料和化学品算作浆料来制备的，然后在浇筑新混凝土之前将其涂在旧混凝土的名义上。它们不得当用于伸缩缝，而仅适用于建筑接缝。

With this method, resins or other proprietary fluid is injected under pressure through perforated or permeable hoses/tubes that have been preinstalled on the old concrete before the pour of the new concrete. This is done after temperature and shrinkage movements have stabilized sufficiently, and the resin flows out of the hose into cracks, fissures, or holes in the joint, thereby sealing the water paths in the joint. This is suitable for construction joints only.
接纳这种圭臬时，在浇注新混凝土之前，通过事前安装在旧混凝土上的穿孔或渗透软管/管，在压力下注入树脂或其他出奇流体。这是在温度和减轻明白充分结识后完成的，树脂从软管流出，参加讨论上的症结、症结或孔洞，从而密封讨论中的水路。这种圭臬仅适用于施工接缝。
