Protection strengthening method for blocking wall structure
The invention provides a protection strengthening method for a blocking wall structure. The blocking wall structure is located above a tunnel. The blocking wall structure comprises a blocking wall foundation and a blocking wall spliced with the blocking wall foundation. The protection strengthening method for the blocking wall structure includes the steps that a supporting frame is erected on a blocking wall; multiple first positioning holes are formed in structural steel; the structural steel with the multiple first positioning holes is placed on the supporting frame, and multiple second positioning holes are drilled in the blocking wall in a one-to-one corresponding manner based on the positions of the multiple first positioning holes; the relative positions between the first positioningholes in the structural steel and the corresponding second positioning holes are corrected; expansion bolts penetrate the first positioning holes and the second positioning holes and then are used for firmly fixing the structural steel on the blocking wall; and two sections of structural steel at the corners of the blocking wall are welded through a steel plate. By means of the technical scheme,the problem that when a blocking wall in the prior art is settled or bulged, cracking or sinking is likely to happen is solved effectively.
本发明提供了一种挡墙结构的防护加固方法，挡墙结构位于隧道的上方，挡墙结构包括挡墙基础和与挡墙基础拼接的挡墙，挡墙结构的防护加固方法包括：在挡墙上搭建支撑架；在型钢上形成多个第一定位孔；将带有多个第一定位孔的型钢放置在支撑架上，利用多个第一定位孔的位置，在挡墙上一一对应地钻出多个第二定位孔；校正型钢上的第一定位孔与对应的第二定位孔的之间的相对位置；膨胀螺栓穿过第一定位孔和第二定位孔后将型钢紧固在挡墙上；挡墙的转角处的两段型钢通过钢板进行焊接。本申请的技术方案有效地解决了相关技术中的挡墙沉降或隆起时容易产生的开裂或者沉陷的问题。
