Crack reinforcing method for subway tunnel construction
The invention discloses a crack reinforcing method for subway tunnel construction, and relates to the technical field of constructional engineering. The crack reinforcing method comprises the following operation steps that S1, a tunnel wall crack opening is excavated, the crack opening is excavated into a V-shaped groove with narrow inside and wide outside, and an included angle between two side walls of the V-shaped groove is between 60 degrees and 90 degrees; S2, a row of nail inserting holes are formed in each of the two side walls of the V-shaped groove, the distance between the two nail inserting holes in each row of nail inserting holes ranges from 0.2 m to 0.3 m, the nail inserting holes are parallel to the wall face of the tunnel wall, and the included angles between the nail inserting holes and the side walls of the V-shaped groove range from 30 degrees to 60 degrees; and S3, the interior of the V-shaped groove is cleaned with water, and the two side faces of the V-shaped groove are polished with steel wire balls while the interior of the V-shaped groove is cleaned with water. According to the crack reinforcing method for subway tunnel construction, the cracking force of the tunnel wall can be resisted, the phenomena of secondary cracking and water seepage of cracks after repairing are avoided, and the high-quality repairing and reinforcing effects are achieved.
本发明公开了一种地铁隧道施工用裂缝加固方法，涉及建筑工程技术领域，包括以下操作步骤：S1、开凿隧道墙体裂缝口，把裂缝口开凿成内窄外宽的V型凹槽，且V型凹槽的两侧壁之间的夹角在60度～90度之间；S2、在V型凹槽的两侧壁上均开设一排插钉孔，且每排插钉孔中的两个插钉孔之间的间距在0.2米～0.3米之间，所述插钉孔与隧道墙体的墙面相平行，所述插钉孔与V型凹槽的侧壁之间的夹角在30度～60度之间；S3、用水清洗V型凹槽的内部，在用水清洗的同时并用钢丝球打磨V型凹槽的两侧面。该一种地铁隧道施工用裂缝加固方法，能够抵抗隧道墙体的开裂力，避免裂缝在修补后再次开裂、渗水的现象，实现高质量的修补、加固效果。
