Grouting method for preventing settlement in cross tunnel construction
The invention relates to a grouting method for preventing settlement in cross tunnel construction, which belongs to the technical field of building construction, and comprises the following steps: S1, arranging grouting holes in the inverted arch and two side positions of the existing tunnel, and performing grouting reinforcement; s2, the newly-built tunnel is expanded outwards in the interval in the direction of the subway tunnel face, and pre-grouting reinforcement is conducted; and S3, the newly-built tunnel is excavated, and reinforcing grouting is carried out in the excavation process, when the newly-built tunnel is excavated, the stability of the existing tunnel is guaranteed, the existing tunnel is not prone to sedimentation, meanwhile, pre-grouting reinforcement is carried out on the newly-built tunnel, the newly-built tunnel is more stable, in the excavation process of the newly-built tunnel, the construction period is shortened, and the construction efficiency is improved. The condition of the existing tunnel can be observed at any time, if the existing tunnel settles, reinforcing grouting can be conducted in time, and the effect of preventing settlement is achieved.
本申请涉及一种交叉隧道施工预防沉降的注浆方法，属于建筑施工的技术领域，其包括以下步骤：S1、对既有隧道仰拱及两侧位置布置注浆孔，进行注浆加固；S2、对新建隧道沿着地铁掌子面方向区间外扩，进行预注浆加固；S3、对新建隧道进行开挖，在开挖的过程中同时进行补强注浆,本申请在开挖新建隧道时，保证既有隧道的稳定性，使既有隧道不易发生沉降，同时新建隧道进行预注浆加固，也使得新建隧道更加稳定，而且在新建隧道的开挖过程中，可以随时观测既有隧道的情况，若既有隧道发生沉降，可及时进行补强注浆，达到预防沉降的效果。
