新型便携式防渗堵漏灌浆设备及其工程应用
发布时间：2019-03-17 08:49
【摘要】：引黄入洛工程隧洞部分衬砌段需要进行防渗堵漏灌浆处理,由于隧洞埋深大、灌浆部位与地面灌浆设备距离长、防渗堵漏需要的灌浆量不大,因此常规的灌浆设备体型大、操作复杂,在此使用效率低、灌浆浪费大。为解决现有灌浆设备用于小范围、间隙式、少浆量防渗堵漏等灌浆施工的技术局限性,研发了便携式灌浆设备。该设备由加压接口、储浆筒、进料口、密封机构及出浆接口构成,通过动力源将加压气体注入密封储浆筒中形成高压气体,通过高压气体将储浆筒中的浆体注入缝隙或空隙进行封堵防渗。利用隧洞内的空压机等动力源作为高压空气源,直接在灌浆部位附近拌制灌浆液,可以进行单液、双液或多液灌浆,结构简单、体积小、质量轻、制作经济、操作简单,使用和维修成本低,可随意移动,已成功应用于隧洞工程的防水堵漏灌浆施工。工程实践表明,该灌浆设备能有效地降低施工成本,效率高、效果好,工程适用性很强,具有推广应用价值。
[Abstract]:Due to the large buried depth of the tunnel, the distance between the grouting site and the ground grouting equipment is long, the grouting quantity required for the seepage prevention and leakage blocking is not large, so the conventional grouting equipment is large, and the grouting equipment is large because of the large buried depth of the tunnel and the long distance between the grouting site and the ground grouting equipment. The operation is complex, the use efficiency is low, and the grouting waste is large. In order to solve the technical limitation of the existing grouting equipment used in the grouting construction, such as small scope, gap type and less grouting quantity, the portable grouting equipment has been developed. The equipment is composed of a pressure interface, a pulp storage tube, a feed port, a sealing mechanism and a slurry outlet. The pressurized gas is injected into the sealed slurry storage tube through the power source to form a high pressure gas. Through the high pressure gas, the slurry in the storage tube is injected into the gap or gap to seal the anti-seepage. Using the air compressor and other power sources in the tunnel as the high pressure air source, mixing the grouting fluid directly near the grouting site, it can be used for single-liquid, double-liquid or multi-liquid grouting. The structure is simple, the volume is small, the weight is light, the manufacture is economical, and the operation is simple. With low cost and free movement, it has been successfully used in waterproofing and leakage grouting construction of tunnel engineering. The engineering practice shows that the grouting equipment can effectively reduce the construction cost, high efficiency, good effect, strong applicability of the project, and has the value of popularization and application.
