开口型钢灌浆加固隧道的施工方法
摘要：
本发明提供了一种开口型钢灌浆加固隧道的施工方法，包括如下步骤：(1)首先对隧道变形情况进行测量，根据测量结果，制作多个开口型钢单元，开口型钢单元的形状与盾构管片待加固的内弧面相吻合；(2)在盾构管片待加固的内弧面上安装开口型钢：依序将多个开口型钢单元相互固定串接，以形成开口型钢，开口型钢内部形成中空的一圆弧管通道；(3)提供多个固定连接件，以分别将各个开口型钢单元固定在盾构管片待加固的内弧面上；(4)在开口型钢上设置填充孔，通过填充孔灌注入填充物。在对原隧道结构进行加固处理时具有加固效果好、成本低、工期短、随型性高等特点。
摘要（英）：

The invention provides a construction method for opening section steel grouting to reinforce a tunnel. The method comprises the following steps: (1) firstly, measuring tunnel deformation conditions, according to a measurement result, manufacturing a plurality of opening section steel units, the shapes of the opening section steel units being matched with a to-be-reinforced intrados of a shield segment; (2) installing the opening section steel on the to-be-reinforced intrados of the shield segment; fixing and connecting the plurality of opening section steel units in series in sequence to form the opening section steel, a hollow circular arc pipe channel being formed in the opening section steel; (3) providing a plurality of fixing connecting pieces to respectively fix the opening section steel units on the to-be-reinforced intrados of the shield segment; (4) and arranging filling holes on the opening section steel, and injecting filler through the filling holes. The method is characterized by good reinforcing effect, low cost, short construction period, and high shape forming property in reinforcing processing on an original tunnel structure.
