Pulse type grouting machine and double-liquid grouting construction method
The invention provides a pulse type grouting machine and a double-liquid grouting construction method. The quincuncial pile type is adopted to arrange grouting holes; grouting is carried out on one point of a central area; grouting is dense without a dead angle, the grouting effect is excellent, the grouting pressure is low, and the grouting efficiency is high; and a cabin is unlikely to be blocked on the condition that the condensation rate of mixed slurry is higher. High and low pressure peak load shifting grouting of the pulse type grouting machine is used to realize premixing; secondary mixing in a mixing pipe and third-time in-depth mixing of a vibrator are realized; the grouting speed is controllable; and on the condition that the slurry is excellent in underwater dispersity resistance and high in cohesiveness, the mixing efficiency and the uniform degree are improved. A A-component single fluid and a B-component signal fluid are designed; the single fluid components can work fora long time; when the double fluid is mixed, the underwater dispersity resistance is high, the condensation and hardening rate is high, and the underwater rapid repairing demand of a railway tunnel foundation disengaging area is met; double-liquid grouting does not affect construction due to pipe blocking caused by excessively high condensation rate. The proportion of the component A and the component B can be controlled to adjust the working time of the mixed slurry.
本发明提供了一种脉冲式注浆机、一种双液注浆施工方法，采用梅花桩型布置注浆孔中间区域一点注浆的方式进行注浆，注浆密实无死角，注浆效果好，注浆压力小效率高，混合浆液凝结速度较快的情况下也不容易堵仓。使用脉冲式注浆机高低压错峰注浆实现预混，混合管二次混合，振动器三次深混，注浆速度可控，在浆体水下抗分散性好、粘聚性高的情况下，提高了混合效率和均匀程度。设计的A、B组分单液，单液组份可工作时间长，当双液混合后，水下抗分散性好，凝结硬化速度快，满足铁路隧道地基脱空区域水下快速修补的需求，且双液注浆不会因为凝结速度过快堵管而影响到施工。可通过控制A组分和B组分的比例可调整混合浆液的可工作时间。
