Technical Field
[0001] The utility model relates to the technical field of steel pipe lock buckles, in particular to a self-waterproof pipe curtain steel pipe lock buckle structure. Background Art
[0002] When an urban highway tunnel passes under an existing highway subgrade, in order not to interrupt the operation of the existing highway and to ensure that the settlement of the existing highway subgrade is controlled within strict standards, a tunnel excavation method under strong pre-support is often used to pass through the highway subgrade section. Among them, small-diameter pipe curtain support has gradually been widely used. The steel pipes of the pipe curtain are rigidly connected into a whole through lock buckles to improve the overall stiffness of the pipe curtain structure. The pipe curtain lock buckle device is particularly important in ensuring the overall stiffness of the pipe curtain. When the current pipe curtain steel pipe lock buckle is used, the pipe buckle needs to be grouted twice to stop water in order to achieve the purpose of waterproofing, which is not convenient to use.
