Grouting method for overlying deep loose sand layer near sea
The invention discloses a grouting method for a near-seaborne overlying deep loose sand layer, which comprises the following steps: a hole opening step: forming a molded hole in a stratum, the hole depth of the molded hole being greater than the distance from the earth surface to a bedrock; in the erecting step, a first grouting pipe and a second grouting pipe are both placed in the hole, a partition piece is arranged on the first grouting pipe, the second grouting pipe is located above the partition piece, the partition piece is located in the hole, the partition piece is located above bed rock, the partition piece divides the hole into an upper hole section and a lower hole section, and the upper hole section and the lower hole section are communicated with each other. The upper hole section and the lower hole section are in a non-communicated state; second grout is injected into the upper hole section through a second grouting pipe, after the upper hole section is filled with the second grout and the second grout is completely solidified, first grout is injected into the lower hole section through a first grouting pipe, and the volume of the injected first grout is larger than that of the lower hole section.
本申请公开了近海上覆深厚松散砂层用注桨方法，包括以下步骤，开孔步骤：在地层上开设型孔，且所述型孔的孔深大于地表到基岩的距离；架设步骤：将第一注浆管与第二注浆管均放置于型孔内，所述第一注浆管上设置有分隔件，所述第二注浆管位于分隔件的上方，所述分隔件位于型孔内，所述分隔件位于基岩的上方，分隔件将型孔分隔成了上孔段以及下孔段，所述上孔段与下孔段处于不连通的状态；注浆步骤：通过第二注浆管向上孔段内注入第二号浆液，待第二号浆液充满上孔段且第二号浆液完全凝固之后，再通过第一注浆管向下孔段内注入第一号浆液，且所注入的第一号浆液的体积大于下孔段的体积。
