Trenchless repair device and method for partial incomplete collapse of double-wall corrugated pipe
The invention relates to the technical field of trenchless repair equipment and method under the pipeline collapse deformation working condition, in particular to a trenchless repair device and methodfor partial incomplete collapse of a double-wall corrugated pipe. The repair device comprises a steel expansion ring, a steel expansion ring supporting device and a collapse opening device. The steelexpansion ring supporting device comprises a left end cover, a right end cover, a repair driving device and a pushing-away device, the steel expansion ring is arranged between the left end cover andthe right end cover, and the repair driving device is fixedly installed in the steel expansion ring. The repair method includes the steps that inspection well spaces at the two ends of a to-be-repaired pipeline are fully utilized, after an incomplete collapse pipe section is fully opened through expanding plates of the collapse opening device, the steel expansion ring is positioned on the incomplete collapse pipe section through the steel expansion ring supporting device, and partial repair of the small-pipe-diameter double-wall corrugated pipe is achieved under the condition that ground excavation is not needed. Time and labor are saved, the road surface is not damaged, and meanwhile the problems of safety accidents and environmental pollution caused by locking in the excavation process are avoided.
本发明涉及管道塌陷变形工况下的非开挖修复设备及修复方法技术领域，是一种双壁波纹管局部不完全塌陷的非开挖修复装置及修复方法；修复装置包括包括钢胀圈、钢胀圈支撑装置和塌陷撑开装置；钢胀圈支撑装置包括左端盖、右端盖、修复驱动装置和推开装置，在左端盖与右端盖之间设置有钢胀圈，在钢胀圈内固定安装有修复驱动装置，修复方法能够充分利用待修复管道两端的检查井空间，通过塌陷撑开装置的扩径板将不完全塌陷管段充分撑开后，再通过钢胀圈支撑装置将钢胀圈定位于不完全塌陷管段，实现在无需地面开挖条件下对小管径双壁波纹管的局部修复；不仅省时省力，而且不破坏路面，同时避免发生开挖过程中锁引发的安全事件和环境污染问题。
