Real-time rubber waterstop monitoring method for immersed tunnel and rubber waterstop

Abstract

The invention discloses a real-time rubber waterstop monitoring method for an immersed tunnel. By acquiring operation data of the rubber waterstop in the immersed tunnel in real time and comparing the operation data with experiential data of the rubber waterstop so as to analyze real-time operation state of the rubber waterstop, real-time monitoring for the rubber waterstop is realized, faulted rubber waterstop can be maintained or replaced immediately when any abnormality is found, and practical significance is realized for safety operation of the tunnel. The invention further discloses the rubber waterstop which comprises a rubber body with a middle air bag, strengthening curtain cloth for increasing compressive strength of the rubber waterstop is arranged inside rubber of the middle air bag, an air nozzle is arranged on the middle air bag, and an air gauge is arranged outside the air nozzle; the middle air bag penetrates a waterstop body and is connected with the outside via the air nozzle which is provided with the digital-display air gauge, so that relative air exchange and quantified internal pressure adjustment can be performed, and quantified adjustment and control for compression amount of the rubber waterstop are achieved.

Description

technical field [0001] The invention relates to a real-time monitoring method for a rubber waterstop, in particular to a real-time monitoring method for a rubber waterstop for immersed tube tunnels and an inflatable rubber waterstop. Background technique [0002] At present, concrete usually has three water-stop systems according to the structure type of joint water-stop: water-stop at the bottom of the joint, water-stop in the middle of the joint, and water-stop at the surface of the joint. Generally, for the key parts of key projects, three waterstop systems are usually used at the same time, but many projects usually only set up a waterstop system in the middle of the joint; during the construction process, the structure of the deformation joint is complex, and the waterstop construction is set inside it. It is difficult, and at the same time, it is easy to displace and deform the installed waterstop during the construction process, making it difficult to ensure the insta...

Problems solved by technology

[0004] 1. The precision requirement is high, and quantitative control cannot be performed in the actual operation process. During the installation process, due to the high requirements for the sinking accuracy of the pipe joints of the immersed tunnel, the sinking cannot be achieved by adjusting the compression height of the GINA rubber waterstop. The alignment connection of pipe joints often causes skewing during installation, etc.

[0005] 2. The process function is relatively single, and it is impossible to quantitatively monitor the compression of the GINA rubber waterstop, and it is impossible to predict the waterstop operation of the GINA rubber waterstop in advance.

[0006] 3. Due to the existence of rubber slack, it is easy to cause the water-stop function to fail, and the conventional structure is not restorative, and the repair cannot be completed after the water-stop fails

[0007] 4. The cost of the GINA rubber waterstop with the same structure is relatively high, and the amount of material required is large, so a large amount of rubber must be used to fill the main part of the GINA rubber waterstop

The above two structures can realize the water-stop function of simple strip seams and flat seams, but neither has a fixed function, will cause floating, has high requirements on the installation surface, and the compression is relatively small, so it is not suitable for deep water fields and immersed tubes Waterproof function in the field of flexible joints for tunnels
