Self-propelled large-scale tunnel air bag plugging device
The invention discloses a self-propelled large-scale tunnel air bag plugging device which comprises an air bag body and propelling devices symmetrically arranged at the two ends of the air bag body, each propelling device comprises a mounting support, a first propeller and a second propeller, and the air bag body comprises an air bag layer and an air bag column. The underwater unmanned plugging device has the following beneficial effects that the propelling devices are arranged at the two ends of the airbag body, so that underwater unmanned plugging is achieved, and the safety can be greatly improved; the air bag body adopts a multi-layer and multi-chamber design, so that the rubber layer of the air bag has a pressing effect on a hole wall during air inflation so as to realize effective plugging, and a certain buffer time can be provided for evacuation of personnel and equipment during construction when the air bag leaks air; the inside of the air bag layer and the inside of the air bag column are the net-shaped reinforcing layers made of the high molecular weight polyethylene fibers or the aramid fibers, and the reinforcing layers can provide main strength support and provide enough bearing force for the air bag body to resist the pressure of a water head.
本发明公布了一种自推进式大尺度隧洞气囊封堵装置，包括气囊本体和对称设置在气囊本体两端的推进装置，推进装置包括安装支架、第一推进器和第二推进器，气囊本体包括气囊层和气囊柱，本发明的有益效果如下：在气囊本体的两端设置推进装置，从而实现水下无人封堵，可以极大的提高安全性；本发明中的气囊本体采用多层多室的设计，既实现气囊的橡胶层在充气时对洞壁的压紧作用而实现有效封堵，也可以保证在气囊漏气时，为施工中的人员与设备的撤离，提供一定的缓冲时间；将气囊层和气囊柱的内部为高分子量聚乙烯纤维或芳纶纤维制成的网状的增强层，增强层可以提供主要的强度支撑，并为气囊本体抵抗水头的压力提供足够的承载力。
