| 1 .确定防水堵漏方案： 1. to determine the waterproof 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. 2.材料性能特点： 2. properties of material: 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. 3.灌浆孔的设计和布孔： 3. the design and perforation 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，缝隙小则孔距小点击免费下载海量工程资料。 (2) hole principle: the position and number of grouting holes, need reasonable arrangement according to different Water Leakage, Water Leakage to export for the purpose of the focus at Water Leakage cloth hole, crack, water flow, hole distance, the gap is small hole distance and small massive engineering data for free download. 4、打孔 4. Punching 可视施工条件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 used for visual construction, usually by manual drilling and mechanical drilling. 5、检查灌浆设备和管路运转情况 5. Check the operation of the grouting equipment and pipeline 检查固结浆嘴的强度，疏通裂缝，进一步设定好灌浆参数（如凝胶时间、灌浆压力和配浆量等）。 The strength of the consolidated slurry nozzle is checked, the cracks are dredged, and the grouting parameters (such as gel time, grouting pressure and slurry amount, etc.) are set up. 6、灌浆 6. Grouting 灌浆是整个化学灌浆的中心环节，须待一切准备工作完成后进行。灌浆前有组织的进行分工，固定岗位，尤其需要有专职熟练的人员进行操作。 The grouting is the central link of the whole chemical grouting, and it must be done after all the preparatory work is completed. Before the grouting, there are organized division of labor, fixed positions, especially the need for full-time and skilled personnel to operate. （1）灌浆前对整个系统进行全面的检查，在灌浆机具运转正常，管路畅通的情况下，方可灌浆。 (1) a comprehensive inspection of the whole system before the grouting is carried out. In the case of the normal operation of the grouting equipment and the smooth flow of the pipes, the grouting can be made. （2）对于垂直缝一般自下而上灌浆，水平缝由一端向另一端或从两头向中间灌浆；对集中漏水应先对漏水量最大的孔洞进行灌浆。 (2) for vertical joints, grouting is usually done from bottom to top, and horizontal joints are grouted from one end to the other or from two sides to the middle. For centralized leaking, we should first fill the holes with the largest leakage. 7、结束灌浆： 7, end grouting: 在压力比较稳定的情况下，再继续灌1-2分钟既可结束灌浆，拆卸管路准备清洗。 In the case of stable pressure, 1-2 minutes of continuous irrigation can not only end the grouting, but also remove the pipe for cleaning. 8、封孔： 8. Sealing the hole: 经检查无漏水现象时，卸下灌浆头，用水泥砂浆等材料将孔补平抹光。 When the water leakage phenomenon is checked, the grouting head is unloaded and the hole is smoothed with cement mortar and other materials. 9、注意事项： 9. Note: （1）输浆管必须有足够的强度，装拆方便点击免费下载海量工程资料。 (1) the slurry pipe must have sufficient strength and convenient loading and dismantling for free download of mass engineering data. （2）所有操作人员必须穿戴必要的劳动保护用品。 (2) all operators must wear the necessary labor protection supplies. （3）灌浆时，操作泵的人员应时刻注意浆液的灌入量，同时观察压力变化情况。一般压力突然升高可能由于浆液凝固、管路堵塞或由于浆液逐渐充填沉降缝，此时立即停止灌浆。压力稳定上升，但仍在一定压力之内，此时是正常的。有时出现压力下降情况，这可能是由于孔隙被冲开，浆液大量进入沉降缝深部所致，此时可持续灌浆。随着大量浆液进入缝隙，压力会逐渐上升并稳定。压力降低的另一个原因是由于封缝或管道接头漏浆造成的，需及时停止灌浆，进行处理。有时由于泵压力增大，将浆液压入沉降缝深处，使大量浆液流失，这时可调节浆液固结时间，使之缩短凝结时间或采用间歇灌浆的方法来减少浆液损失。 (3) at the time of grouting, the personnel of the pump should always pay attention to the size of the slurry and observe the change of the pressure. The sudden increase in pressure may be due to the solidification of the slurry, the blockage of the pipeline, or the gradual filling of the settlement seam due to the slurry, and the grouting is stopped immediately. The pressure rises steadily, but it is still within a certain pressure, and it is normal at this time. Sometimes the pressure drop, which may be due to the pore open and poured into the deep slurry settlement caused by the sustainable grouting. As a large number of slurry enters the gap, the pressure will gradually increase and stabilize. Another reason for the reduction of pressure is due to the slit or the leakage of the pipe joint. It is necessary to stop the grouting in time and carry out the treatment. Sometimes, because of the increase of pump pressure, the slurry is hydraulically poured into the deep part of the settlement joint, resulting in the loss of a large number of slurry. At this time, the consolidation time of slurry can be adjusted to shorten the setting time or to reduce the loss of slurry by intermittent grouting. （4）灌浆所用的设备、管路和料桶必须分别标明。 (4) the equipment, pipes and barrels used for grouting must be marked separately. （5）灌浆前应准备水泥、水玻璃等快速堵漏材料，以便及时处理漏浆跑浆情况。 (5) the rapid plugging material such as cement and water glass should be prepared before grouting so as to deal with slurry running in time. （6）每次灌浆结束后，必须及时清洗所有设备和管道，灌浆结束后应用1：2水泥砂浆封闭灌浆孔。 (6) after the end of each grouting, all the equipment and pipes must be cleaned in time. After the grouting, 1:2 cement mortar is used to seal the grouting holes. |
