Slurry formula of shield tunnel and grouting construction method
The invention discloses a slurry formula of a shield tunnel and a grouting construction method.The slurry formula changes along with different grouting distances of the shield tunnel, and the grouting construction method comprises the steps that a horizontal cement tank, a first mortar tank, a stirring tank and a ground grouting machine are sequentially arranged on the ground, and a second mortar tank is arranged on a tunnel portal wall platform; a third mortar tank is arranged at the position of a shield tunnel portal, grouting pumps are arranged at the positions, 900 m and 1800 m away from the portal, of the portal, and grouting machines are arranged at tunnel leakage points; a grout formula is adjusted according to different grouting distances, grout is conveyed to a stirring tank, a ground grouting machine, a second mortar tank, a third mortar tank, a grouting pump and a grouting machine, and grouting is conducted on leakage points; and the steps are repeated, and grouting is conducted on different leakage points. The formula of the slurry can be used for grouting of a high-water-head, large-burial-depth and long-distance shield tunnel, the construction method can uninterruptedly block leakage points within 24 hours, and the slurry is high in efficiency, low in cost, high in safety and good in application prospect.
本发明公开了一种盾构隧道的浆液配方及注浆施工方法，浆液配方随盾构隧道注浆距离的不同而变化，注浆施工方法包括将卧式水泥罐、第一砂浆罐、搅拌罐、地面注浆机依次设于地面上，将第二砂浆罐设于洞门墙平台上，将第三砂浆罐设于盾构隧道洞口处，在洞口、距洞口900m、1800m处设注浆泵，在隧道渗漏点设注浆机；根据不同注浆距离调节浆液配方，将浆液输送至搅拌罐、地面注浆机、第二砂浆罐、第三砂浆罐、注浆泵直至注浆机，对渗漏点注浆；重复前述步骤，对不同渗漏点注浆。本发明的浆料配方可用于高水头大埋深长距离盾构隧道的注浆，施工方法可24小时不间断对渗漏点进行封堵，效率高，成本低，且安全性高，具有很好的应用前景。
