Construction method for underground diaphragm wall grooving
The invention discloses an underground diaphragm wall grooving construction method which comprises the steps that a groove body is excavated in a groove section where a guide wall is constructed, and slurry is introduced into the groove body; before the groove body is excavated, the groove body is sequentially divided into a first groove section, a second groove section and a third groove section in the length direction; the first groove section and the third groove section are excavated; when the first groove section and the third groove section are excavated to a preset distance from a rock stratum, drilling a guide hole with a preset length; the first groove section and the third groove section are excavated to form groove sections with preset depths; and the second groove section is excavated, and an underground diaphragm wall groove body is formed. According to the technical scheme, the hole guiding perpendicularity of the drilling equipment can be guaranteed, and then it is guaranteed that the groove wall of the groove body is perpendicular.
本发明公开一种地连墙成槽的施工方法，地连墙成槽的施工方法包括：在施工完导墙的槽段内开挖槽体，并在所述槽体内引入泥浆；在开挖所述槽体前，将所述槽体沿长度方向依次分成第一槽段、第二槽段和第三槽段；进行所述第一槽段和所述第三槽段的开挖；在所述第一槽段和所述第三槽段开挖至与岩层预设距离时，钻设预设长度的引孔；将所述第一槽段和所述第三槽段开挖形成预设深度的槽段；进行所述第二槽段的开挖，形成地下连续墙槽体。本发明技术方案可以保证钻孔设备引孔垂直度，进而确保槽体的槽壁垂直。
