高压注浆防水堵漏有用吗
Is high-pressure grouting waterproof and plugging useful
高压注浆的耐久性并没有保障，裂纹是会不断扩大的。高压注浆防水堵漏它的耐久性有20到30年。
The durability of high-pressure grouting is not guaranteed, and the crack will continue to expand. High pressure grouting waterproof plugging, its durability has 20 to 30 years.
1.了解渗漏位置
1. Understand the leakage location
补漏动工前，我们需要对即将进行补漏的部位进行实地勘察，了解清楚实际情况，找到漏水的原因，准确的了解漏水部位、裂纹或穿孔的长、宽和等情况，另外，还要了解雨天、晴天的漏水流量与流速等，综合所有情况正确制定高压注浆防水补漏施工方案，同时做好各项准备工作。
Before the construction of leakage repair, we need to conduct field investigation on the parts to be repaired to understand the actual situation, find out the causes of leakage, accurately understand the length, width and other conditions of leakage parts, cracks or perforations, in addition, we also need to understand the leakage flow and flow rate in rainy and sunny days, correctly formulate the construction scheme of high-pressure grouting waterproof leakage repair based on all conditions, and make various preparations at the same time.
2.材料性能特点
2. Material performance characteristics
油性聚氨酯材料遇水就会产生反应，所以浆液不会因为与水相融就被稀释，这也是别的灌浆材料所不具备的特性之一，在高压作用下，浆液被灌入缝隙或孔洞之中，同时向缝隙周围，较终形成网状结构，形成密度小的弹性体，从而实现了补漏的效果。
The oily polyurethane material will react with water, so the slurry will not be diluted because it melts with water, which is also one of the characteristics that other grouting materials do not have. Under the action of high pressure, the slurry is poured into the gap or hole, and finally forms a mesh structure around the gap to form an elastomer with low density, so as to realize the effect of leakage repair.
3.灌浆孔的设计和布孔
3. Design and layout of grouting holes
结合实际情况来选择灌浆孔的形式，通常有骑缝、斜孔这两种方式，必要时，有可能两种结合使用。值得注意的有两点，一是：灌浆孔的位置要让孔和漏水裂缝空隙相交，并选在漏水量的地方；二是：注浆孔眼的位置和数量，要依据漏水情况合理设计。
The form of grouting hole shall be selected according to the actual situation. There are usually two ways: cross joint and inclined hole. If necessary, the two methods may be used in combination. It is worth noting that there are two points: first, the position of grouting hole should make the hole intersect with the gap of water leakage crack, and select the place with water leakage; Second, the location and quantity of grouting holes should be reasonably designed according to the water leakage.
4.高压灌浆
4. High pressure grouting
灌浆过程其实是一个化学反应的过程，一切准备就绪之后，需对灌浆工作进行合理的分工，选择技术熟练的技术员准备操作，在确保灌浆机运转正常、管路之后可灌浆。防水补漏施工方案中的每一个步骤都至关重要，丝毫不能懈怠，如果没有严谨的对待工作，很有可能劳心费力白忙活一场，有保险的防水补漏服务才更靠谱。
The grouting process is actually a process of chemical reaction. After everything is ready, it is necessary to reasonably divide the grouting work, select skilled technicians to prepare for operation, and grout after ensuring the normal operation of the grouting machine and the pipeline. Every step in the waterproof and leak repair construction scheme is very important, and we can't slack off at all. If we don't treat the work strictly, we are likely to work hard for nothing, and the waterproof and leak repair service with insurance is more reliable.
