Waterstop protection device and immersed tube tunnel structure comprising device
The invention relates to the technical field of sea bottom immersed tube tunnels, and provides a waterstop protection device. The waterstop protection device is arranged between joints of two sections of an immersed tube, and comprises a steel plate protection cover, wherein the steel plate protection cover is positioned at the outer side of the waterstop and is formed through splicing welding, the joint parts of adjacent steel plates of the steel plate protection cover adopt a seamless welding mode, and in addition, additional welding processing is carried out; sponge rubber is arranged in inner positions, near the two ends, of the steel plate protection cover. A seamless welding mode is adopted between the adjacent steel plates, and in addition, the additional welding processing is carried out, so that the connecting sealing performance between the steel plates and concrete immersed tube sections is improved, the whole waterstop protection device forms a more sealed space, the goal of isolating air, dust, water and the like is achieved, the problem of waterstop corrosion damage due to contact of the waterstop with the air and the water is effectively solved, and the service life of the immersed tube is ensured.
