Waterproof leaking stoppage connecting device for connecting channel and main line tunnel

The invention discloses a waterproof leaking stoppage connecting device for a connecting channel and a main line tunnel, and relates to the technical field of pipeline connection, and the waterproof leaking stoppage connecting device adopts a quick-setting inorganic leaking stoppage material and L-shaped angle steel as waterproof lines of a connecting port to prevent the problems of leakage and the like at the connecting port. Meanwhile, the sulphoaluminate micro-expansive concrete is adopted to fill the steel separation cavities, the structural strength and stability of the steel separation cavities are improved, the construction method is simple and easy to operate, the problem of connector leakage is avoided, the later maintenance rate is reduced, and comprehensive benefits are considerable. Project field practical verification shows that the method is feasible and has high safety and popularization and application value. 本发明公开了一种用于联络通道与主线隧道的防水堵漏连接装置，涉及管道连接技术领域，该装置采用速凝无机类堵漏材料和L型角钢作为连接口的一道道防水线，防止接口处出现渗漏等问题，
