一种盾构隧道高聚物注浆方法及盾构隧道
摘要：
本发明公开了一种盾构隧道高聚物注浆方法及盾构隧道，一种盾构隧道高聚物注浆方法包括以下步骤：S1：建造隧道本体时，沿隧道本体周面预留出脱空区域，所述隧道本体内设有注浆孔，所述注浆孔从隧道本体内部延伸至脱空区域；S2：在注浆孔内放置注浆管，所述注浆管从隧道本体内部延伸至脱空区域；S3：注浆，通过注浆管将至少两种液态的高聚物注入脱空区域，各高聚物在脱空区域中反应后膨胀凝固成固态并将脱空区域填充满。采用多种高聚物反应膨胀并填充满脱空区域，能够对盾构隧道进行有效防震、防渗，后续的维护等都十分方便。本发明应用于隧道技术领域。
摘要（英）：

The invention discloses a shield tunnel high polymer grouting method and a shield tunnel and belongs to the technical field of tunnels. The shield tunnel high polymer grouting method includes the following steps that S1, when a tunnel body is constructed, a void area is reserved in the circumferential face of the tunnel body, grouting holes are formed in the tunnel body, and the grouting holes extend to the void area from the interior of the tunnel body; S2, grouting pipes are arranged in the grouting holes, and the grouting pipes extend in the void area from the interior of the tunnel body; and S3, grouting is conducted, at least two kinds of liquid high polymers are injected into the void area through the grouting pipes, all the high polymers are reacted and expand in the void area to bein a solid state, and the void area is filled. The various high polymers are reacted and expand so that the void area can be filled, and effective shock prevention and seepage prevention, subsequentmaintenance and the like can be conducted on the shield tunnel and are very convenient.
