[0039] As one of the most important anti-seepage facilities in the foundation engineering of earth-rock dams, the cut-off wall plays an important role in ensuring the safety of the dam and reducing leakage in the reservoir area. In the construction of the cut-off wall, since the joint pipe method is the current advanced technology for the joint treatment of the concrete cut-off wall construction, it has the unparalleled advantages of other joint connection technologies: first, the joint hole construction by the joint pipe method is of better quality , The hole wall is smooth, and it is not easy to form thick mud at the hole end. At the same time, because of its arc specification, it is also easy to brush the joint without leaving dead corners, which can ensure the joint quality of the joint. Secondly, due to the lower setting of the joint pipe, the time for setting the joint concrete is saved, and the work efficiency is improved, which plays a very important role in shortening t...
