Ground grouting construction technology
The invention relates to the technical field of ground surface grouting, in particular to a ground grouting construction technology. Comprising the following steps that S1, a pipeline radar is used for comprehensively detecting a construction area, and the pipeline position is marked on site according to a pipeline geophysical prospecting result; s2, first-stage grouting construction is conducted on the surface shallow hole uncompacted area; s3, after the first-stage grouting construction is completed, a geological radar is adopted for scanning, the non-compaction condition is detected, mechanical drilling coring is adopted, and the grouting result is verified; s4, second-stage earth surface deep hole stratum grouting reinforcement construction is carried out; s5, after the second-stage grouting construction is completed, mechanical drilling and coring are adopted, and the grouting result is verified; according to the method, the ground is grouted in two stages, the local cavity part below the road surface can be densely filled, the stratum above the pipeline can be reinforced, meanwhile, the soil layer which is possibly disengaged or not compact below the pipeline can be reinforced, the soil body below the pipeline is reinforced and hardened, and surface collapse is prevented.
本发明涉及地表注浆技术领域，具体地说，涉及一种地面注浆施工工艺；包括以下步骤：S1、先利用管线雷达对施工区域进行全面探测，根据管线物探结果在现场标识管线位置；S2、进行第一阶段地表浅孔不密实区域注浆施工；S3、第一阶段注浆施工完成后，采用地质雷达扫描，探测不密实情况，采用机械钻孔取芯，验证注浆结果；S4、进行第二阶段地表深孔地层注浆加固施工；S5、第二阶段注浆施工完成后，采用机械钻孔取芯，验证注浆结果；本发明采用两阶段对地面进行注浆，既能对路面下方存在局部空洞部位填充密实，对管线上方地层进行加固，同时也能对管道下方可能脱空或不密实土层进行加固，使管道下方土体进行加固硬化，防止地表塌陷。
