Description

TECHNICAL FIELD

[0001] The utility model belongs to dam pipe gushing plugging technical field, specifically relates to a dam pipe gushing rapid plugging device. BACKGROUND

[0002] Dam pipe gushing is a common dam danger, which refers to the phenomenon that fine particles in cohesionless soil move or are carried out by water flow through the pores formed by coarse particles under the action of seepage force. This phenomenon may lead to the formation of cavities or channels inside the dam, which may cause serious consequences such as dam collapse. Therefore, timely and effective plugging of pipe gushing channels is the key to ensuring the safe operation of the dam and the safety of people's lives and property in the downstream area.

[0003] Chinese patent publication No. CN220335828U discloses a dam pipe gushing plugging device, which adds expansion balls to the delivery cylinder through the lateral feeding pipe, so that the delivery cylinder does not need to be pulled out of the pipe gushing channel when the expansion balls are supplemented, and the sealing of the plug and the bottom block is improved by inflating the air bag. However, the feeding pipe and the feeding bin cannot store expansion balls. If there are expansion balls in the feeding pipe, the expansion balls in the feeding pipe will move above the first piston during the process of the first piston extruding the expansion balls, affecting the lifting of the pressure rod and the first piston. Therefore, expansion balls need to be manually added to the device every time the delivery cylinder is supplemented with expansion balls, which consumes a lot of time and results in insufficient plugging efficiency. In addition, after the plug is close to the bottom block by manually rotating the rotating ring, the air bag needs to be inflated manually to seal the connection between the plug and the bottom block, which has many operation steps and affects the plugging efficiency.
