确定防水堵漏方案

Water proof plugging scheme

堵漏前必须进行现场调查，摸清现场施工情况，分析渗漏水的原因，查清漏水部位、裂缝、裂纹或穿孔的宽度、长度、深度和贯穿情况，并了解雨天和晴天的漏水情况，测量漏水的流量与流速等，通过充分调查，正确拟定堵漏方案，做好各项准备工作。

Must conduct on-site investigation before plugging, to find out the site construction conditions, analysis of the causes of seepage Water Leakage, identify Water Leakage parts, crack, crack or perforation of the width, length, depth and penetration, and to understand the situation Water Leakage sunny and rainy days, the Water Leakage measurement of flow and velocity and so on, through the full investigation, plugging scheme is correct to do the preparatory work.

材料性能特点

Properties of materials

油性聚氨酯注浆材料与水即反应，由于水参与了反应，浆液不会被水稀释冲走，这是其他灌浆材料所不具备的优点，浆液在压力作用下，灌入混凝土缝隙或孔洞，同时向缝隙周围渗透，继续渗入混凝土缝隙，最终形成网状结构，成为密度小，含水的弹性体，有良好的适应变型能力，止水性好。

Oily polyurethane grouting materials and water reaction, because the water in the reaction, the slurry can not be diluted with water washed away, this is the advantage that other filling materials do not possess the slurry under pressure, pouring concrete cracks or holes, at the same time to penetrate the gap around, continue to penetrate into the concrete cracks, and ultimately the formation of network structure, a density a small, elastic body water, has a good ability to adapt to change, good waterproof.

灌浆孔的设计和布孔

The design and distribution hole of the grouting hole

灌浆孔的布孔有骑缝和斜孔两种形式，根据实际情况和需要加以选择，必要时两者并用。

The grouting hole hole perforation and inclined hole two forms to choose according to the actual situation and needs, and both when necessary.

（1）灌浆孔的设计：灌浆孔的位置，应使孔和漏水裂缝空隙相交，并选在漏水量最大处。

(1) the design of the grouting hole: the position of the grouting hole should make the hole intersected with the leakage gap and choose the maximum leakage.

（2）布孔原则：注浆孔眼的位置和数量，需根据不同漏水情况进行合理安排，以导出漏水为目的，在集中漏水处布孔，裂缝大、水流量大则孔距大，缝隙小则孔距小。

(2) the principle of hole placement: the location and quantity of grouting holes should be reasonably arranged according to the different water leakage conditions, so as to derive the aim of water leakage. There are holes in the concentrated water leakage, large cracks, large water flow, large distance between holes, small holes and small distance between holes.

采用手工和机械方法，一般是手工打孔和机械打孔并用。

Manual and mechanical methods are commonly used by manual drilling and mechanical drilling.
