Problems solved by technology

[0003] However, the existing OMEGA waterstop protective cover has the following defects: although the first wooden protective cover can well isolate air and water, it has serious rot and short life due to sinking in the sea for a long time; The cover ensures that the waterstop will not be damaged in the subsequent construction and will not rot for a long time; but it does not have the effect of sealing and waterproofing

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of subsea immersed tube tunnels, in particular to a waterstop protection device and an immersed tube tunnel structure including the device. Background technique [0002] The subsea tunnel immersed tube of the Hong Kong-Zhuhai-Macao Bridge Island Tunnel Project adopts the cross-section form of two holes and one pipe gallery, with a width of 3795cm, a height of 1140cm, a thickness of the bottom plate of 150cm, a thickness of the side web and top plate of 150cm, and a thickness of the middle web of 80cm; each standard pipe section consists of eight It consists of a segment with a length of 22.5m. The waterproof performance of prefabricated immersed pipe construction technology is one of the main indicators for inspecting the quality of pipe joints. Among them, we use OMEGA waterstops for waterproof treatment between each adjacent segment and adjacent pipe sections, so the waterproof performance of OMEGA waters...
