Repairing method for shot hole of submerged cable-stayed floating tunnel
The invention discloses a repairing method for a shot hole of a submerged cable-stayed floating tunnel. The repairing method comprises the following steps of: step 1, preparing a hoop, opening a pouring hole and an exhaust hole on the wall surface of the hoop, fixing a plurality of rubber pads in a spaced manner on the inner wall surface of the hoop, correspondingly fixing two rubber rings to thetwo ends of the hoop, fixedly inserting a grouting duct into the pouring hole of the hoop on land, fixedly inserting an exhaust pipe into the exhaust hole of the hoop, and then conveying the hoop to adamaged part of the tunnel by using a towboat to finish mooring; and step 2, carrying out repairing according to the following damage conditions of the tunnel: carrying out repairing by adopting a method of performing grouting at the outer side of the tunnel if concrete surface peeling off or nonpenetrative cracks are generated; carrying out repairing by adopting a method of tunnel outer side grouting plus tunnel inner side crack pressure grouting if penetrative cracks are generated; and carrying out repairing by adopting a method of tunnel outer side grouting plus tunnel inner hole repairing. The repairing method disclosed by the invention is simple in process, mature in technique, is small in amount of underwater work of divers and low in safety risk.
本发明公开了一种水下斜拉式悬浮隧道子弹孔的修补方法，包括以下步骤：步骤一，准备抱箍，抱箍的壁面上开设灌注孔和排气孔；抱箍的内壁面上间隔地固定若干橡胶垫，并且抱箍的两端各自固定一个橡胶圈；在陆上将灌浆导管固定插置在抱箍的灌注孔中，将排气管固定插置在抱箍的排气孔中，再用拖船将抱箍运至隧道的受损部位后完成系泊；步骤二，根据以下隧道受损情况进行修补：产生混凝土表面剥落或非贯穿裂缝，采用隧道外侧灌浆的方法进行修补；产生贯穿裂缝，采用隧道外侧灌浆+隧道内侧裂缝压力注浆的方法进行修补；产生喷水孔洞，采用隧道外侧灌浆+隧道内侧孔洞修复的方法进行修补。本发明工艺简单，技术成熟，潜水员水下作业量小，安全风险低。
