1 前言所谓堤防锥探灌浆,就是利用锥孔机打孔,而后用泥浆泵把按要求拌制好的浆液,在一定的压力下将泥浆注入堤防土体中土颗粒的间隙内,使其扩散,胶凝或固化,以增加土体强度,降低渗透性,防止变形的一种加固技术。多年实践证明,锥探灌浆是处理堤防隐患,进行堤防加固的一种有效方法。但锥探灌浆工作技术性较强,如果灌浆保证不了质量,不但达不到预期效果,有时还会对堤防造成一定破坏,甚至造成新的隐患。
1 Preface The so-called embankment cone exploration grouting, is the use of tapping hole drilling machine, and then use the mud pump to prepare a good slurry as required, under certain pressure will be injected into the soil dike soil particles in the gap, so that it spread , Gelling or curing, in order to increase soil strength, reduce permeability, prevent deformation of a reinforcement technology. Years of practice proved that cone drilling grouting is an effective way to deal with the hidden dangers of embankments and reinforce the embankments. However, the technical work of geological exploration grouting is quite strong. If the grouting can not guarantee the quality, it will not only fail to achieve the expected results, but also cause some damage to embankments and may even cause new hidden dangers.
