Bridge pile foundation karst grouting pre-consolidation construction system and method
The invention provides a pre-consolidation construction system aiming at the grouting problem of a karst area of a bridge pile foundation. According to the system, the sleeve valve pipe, the rubber plug grouting valve and the double-liquid grouting pump are integrated, and accurate positioning and graded grouting of the karst cavity are achieved. Multiple sets of grouting holes are formed inside and outside the sleeve valve pipe, the sealing performance is ensured through the design of the rubber plug valve, grout conveying and pressure control are optimized through the three-way pipe and the pressurization module, and the grouting efficiency and quality are improved. The construction process covers accurate installation, intelligent grouting regulation and control and later effect evaluation, and the problems of incomplete grouting and unstable structure are effectively solved. According to the system, the construction safety and flexibility are improved, the system has a wide application prospect on bridge pile foundation reinforcement of karst geology, and the technical progress of bridge construction under complex geological conditions is remarkably promoted.
本发明针对桥梁桩基岩溶区注浆难题，提出一种预固结施工系统。该系统整合了袖阀管、胶塞注浆阀与双液注浆泵，实现岩溶空洞精确定位与分级注浆。袖阀管内外分设多组注浆孔，胶塞阀设计确保密封性，三通管与增压模块优化了浆液输送与压力控制，提升注浆效率与质量。施工流程涵盖精确安装、智能调控注浆，及后期效果评估，有效解决注浆不全、结构不稳定问题。该系统提高了施工安全性与灵活性，对岩溶地质的桥梁桩基加固具有广泛应用前景，显著推动了复杂地质条件下桥梁建设的技术进步。
