济南防水http://www.tianyujian.com/分析根据地基加固要求,施工过程中应做好详细施工记录,并进行地面变形测量监控,施工结束后,请提供有关施工报告给设计单位,压密注浆施工需加强施工质量管理。
1、济南防水谈到压密注浆原理是通过注浆管将浆液均匀的注入地层中,浆液以填充、渗透和挤密等方式,赶走土颗粒间或岩土裂隙中的水份和空气后占据其位置,经人工控制一定时间后,浆液将原来松散的土粒或裂隙胶结成一个整体。因考虑到现场的实际情况,注浆量每米孔深注浆水泥用量暂定80kg,水泥浆采用P.O32.5普通硅酸盐水泥配置,水泥浆的水灰比0.5。
Jinan waterproof Speaking after compaction grouting works by injecting grouting pipe uniform slurry formation, slurry to fill, penetration and compaction, etc., off the rock fissures or between soil particles in the water and air to take its position, manual control after a certain time, the original slurry loose soil particles or cracks cemented as a whole. By taking into account the actual situation at the scene, per meter deep hole grouting cement grouting provisional 80kg, grout using ordinary portland cement P.O32.5 configuration, grout cement ratio 0.5.
2、济南防水分析单管静压注浆的压力宜采用低压渗透,注浆速度与注浆压力取值应以地表面冒浆为控制原则。
Jinan waterproof analyze single tube hydrostatic pressure grouting should adopt the low pressure penetration, speed and grouting grouting pressure value should take slurry to the surface control principle.
3、济南防水http://www.tianyujian.com/分析介绍注浆过程中有地下水冒出地面时,需在周围设置排水沟,安排人员用潜水泵排出施工场地;待浆液冒出后,须停止一小段时间后再注浆。
When analyzing Jinan waterproof grouting process describes groundwater out of the ground, set around drains, arrange the construction site with submersible pump discharge; After the slurry out, shall cease for a short time after grouting.
