Construction method for blocking underground river by pouring concrete
The invention discloses a construction method for blocking an underground river by pouring concrete, which comprises the following steps: S1, preliminarily determining the position of the underground river: drilling a hole in a bottom plate of a curtain grouting gallery, and preliminarily determining the position of the underground river through the position of the drilled hole; s2, a to-be-reinforced range is explored, wherein an underwater sonar is lowered through a probe hole, and the to-be-reinforced range of the curtain grouting gallery above the underground river is explored; s3, grouting holes are formed, specifically, the grouting holes are formed in the to-be-reinforced range of the curtain grouting gallery; and S4, grouting and plugging are conducted, specifically, underwater non-dispersible concrete is poured into the grouting holes. The construction method for blocking the underground river by pouring the concrete does not need the forced drainage problem, construction is convenient, the construction difficulty is low, and the construction efficiency and quality can be improved.
本发明公开了一种灌注混凝土封堵暗河的施工方法，包括如下步骤：S1、初步确定暗河位置：在帷幕灌浆廊道的底板上钻探孔，通过钻出探孔的位置，初步确定暗河位置；S2、勘探出待加固范围：通过探孔下放水下声呐，勘探出暗河上方的帷幕灌浆廊道的待加固范围；S3、布置灌浆孔：在帷幕灌浆廊道的待加固范围内布置灌浆孔；S4、灌浆封堵：在灌浆孔内灌注水下不分散混凝土。本灌注混凝土封堵暗河的施工方法无需面临强制排水问题，施工方便，施工难度低，能够提高施工效率和质量。
