Embodiment Construction

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] In this embodiment, an annular construction joint is used as an example for illustration, but of course, it can also be used for other types of construction joints, which will not be repeated here. see Figure 1-Figure 3 , In the mountain tunnel, the tunnel support lining structure includes primary support 1 and secondary lining 2, in which the secondary lining is poured in sections along the longitudinal direction of the tunne...

Abstract

The invention discloses a tunnel lining construction joint waterproof structure. A water stop strip hole way arranged along a construction joint is arranged at the position, positioned at the construction joint, in a tunnel secondary lining, a groove which is arranged along the construction joint and penetrates through the water stop strip hole way is formed in the position, positioned at the construction joint, of the external wall of the tunnel secondary lining. The water stop strip hole way is internally filled with water stop materials to form a water stop strip. The invention further discloses a waterproof method of a tunnel lining construction joint. A drainage channel for circulation of percolating water is formed between the water stop strip and the bottom of the groove, compared with an existing pre-buried type water stop structure, the percolating water can smoothly flow out from both sides of the water stop strip, and hydraulic pressure is not formed to cause invalidation ofthe water stop strip. In addition, the waterproof structure can be conveniently dismantled and replaced after the invalidation of the waterproof structure, and secondary damage is not caused to a tunnel lining.

Description

technical field [0001] The invention belongs to the field of tunnel construction, and in particular relates to a tunnel lining construction joint waterproof structure and a waterproof method. Background technique [0002] Leakage water is the most common disease in tunnel engineering. There is a saying in the industry that there are "nine leaks in ten tunnels", and more than 70% of the seepage water occurs at the lining construction joints. In severe cold areas, water seepage further causes freezing damage, causing structural cracks, lining with ice, and ice accumulation on the pavement, which seriously threatens driving safety. Eliminating the leakage and freezing damage of tunnel lining construction joints is an important subject in the field of tunnel engineering research and engineering practice. [0003] The reasons for the frequent leakage of water in the construction joints of tunnel lining include: (1) a large number of tunnels built in the early days did not have s...
