Raft equipment foundation settlement grouting reinforcement process
The invention discloses a raft equipment foundation settlement grouting reinforcement process, belongs to the technical field of raft foundation settlement reinforcement methods, and effectively solves the problem that an existing raft equipment foundation sinks due to long-term water immersion. Laying a grouting pipe; according to the method, the prepared grout is conveyed to the bottom of a raft equipment foundation through a grouting pump, grouting is stopped after the designed pressure is reached, and the effects of stably sinking and improving the bearing capacity of the foundation are achieved after standing maintenance. According to the method, the slurry is filled, permeated, compacted and the like to drive away moisture and air among soil particles or in rock fractures and then occupy the positions of the soil particles or the rock fractures, original loose soil particles or fractures are cemented into a whole, the composite foundation with high impermeability, stability and strength is formed, time is short, the effect is good, construction difficulty is small, cost is low, and the method is suitable for large-scale popularization and application. And continuous and stable production can be recovered in a production field within a short time.
本发明公开了一种筏板设备基础沉降注浆加固工艺，属于筏板基础沉降加固方法技术领域，有效解决了现有筏板设备基础由于长期浸水导致地基下沉的问题，包括地面钻孔至持力层；敷设注浆管；通过灌浆泵将配置好的浆液通过灌浆泵输送至筏板设备基础底部，达到设计压力之后停止注浆，经过静置养护后达到稳定下沉及提高地基承载能力的效果，其有益效果在于：通过将浆液均匀地注入地层中，使得浆液以充填、渗透和挤密等方式，赶走土颗粒间或岩石裂隙中的水分和空气后占据其位置，将原松散的土颗粒或裂隙胶结成一个整体，形成具有较高防渗性、稳定性及高强度的复合地基，时间短、效果好、施工难度小、成本低，能够在短时间内使生产现场恢复连续稳定生产。
