Abstract
The present invention provides the W type immersed tube tunnel secondary waterproof joint of a kind of improvement, belongs to engineering test and technical field of measurement and test. Comprise GINA waterstop, A type end box hat, Type B end box hat, W type waterstop, GINA waterstop pressing plate, sealing steel disc, W type waterstop pressing plate and compressing tablet. A type end box hat, Type B end box hat and top board or underplate concrete consolidation, GINA waterstop one section is fixed on Type B end box hat. GINA waterstop pressing plate and A type end box hat connect admittedly, the other end of compacting GINA waterstop. Sealing steel disc embeds in concrete, is connected with A type end box hat and Type B end box hat. Threaded stud is through W type waterstop pressing plate and is fixed, and W type waterstop relies on compressing tablet to be fixed on W type waterstop pressing plate. The invention enables the flexible joint of immersed tube tunnel to have good stagnant water effect, effective minimizing is because the damage to flexible joint that axial, vertical, the transversal displacement amount that produce are brought is runed in tunnel for a long time.
Description
Technical field
The invention belongs to engineering test and technical field of measurement and test, it relates to the W type immersed tube tunnel secondary waterproof joint of a kind of improvement.
Background technology
The tunnel joint in immersed tube tunnel is the significant points in immersed tube tunnel, is also weak part simultaneously. Watertightness is one of the factor to be considered of flexible joint, is also one of the most important influence factor simultaneously. The watertightness design of flexible joint, general employing hydraulic pressure connection forms initial closing, and namely adopts GINA rubber fastening band as first waterproof. Then, in the immersed segment forming watertightness, each joint is installed OMEGA rubber fastening band. OMEGA rubber fastening band is the second Lock gate of flexible joint. It is after Guan Jie displays docking, takes out the water between two end-plates, it is achieved crimping under water is formed after watertightness again installs in tunnel pipe.
The axis produced is runed for a long time owing to this waterstop mainly bears tunnel, vertical, transversal displacement amount so that aging, Seepage problems easily occurs in this waterstop.
Summary of the invention
The present invention proposes the W type immersed tube tunnel secondary waterproof joint of a kind of improvement, by this kind of watertightness design, effectively improve the barrier properties of immersed tube tunnel flexible joint, add the work-ing life of flexible joint.
A W type immersed tube tunnel secondary waterproof joint for improvement, comprises GINA waterstop, A type end box hat, Type B end box hat, W type waterstop, GINA waterstop pressing plate, W type waterstop pressing plate, threaded stud, compressing tablet and sealing steel disc. A type end box hat, Type B end box hat respectively with tunnel roof and tunnel underplate concrete consolidation, GINA waterstop one end is fixed on Type B end box hat. GINA waterstop pressing plate and A type end box hat connect admittedly, compacting GINA waterstop. Sealing steel disc embeds in the concrete of tunnel roof and tunnel base plate, is connected with A type end box hat and Type B end box hat. Threaded stud is through W type waterstop pressing plate and is fixed, and W type waterstop is fixed on W type waterstop pressing plate by compressing tablet. Two ends and the threaded stud of W type waterstop are directly fitted, and do not stay gap so that W type waterstop is when being out of shape, compacter.
The useful effect of the present invention is: make the flexible joint of immersed tube tunnel have good stagnant water effect, and can effectively reduce because the damage to flexible joint that axial, vertical, the transversal displacement amount that produce are brought is runed in tunnel for a long time.

In figure: 1, GINA waterstop; 2, GINA waterstop pressing plate; 3, sealing steel disc; 4, Type B end box hat; 5, A type end box hat; 6, W type waterstop pressing plate; 7, W type waterstop; 8, threaded stud; 9, compressing tablet.
Embodiment
Below in conjunction with accompanying drawing and technical scheme, the specific embodiment of the present invention is described further.
As shown in Figure 1, the present invention proposes the W type immersed tube tunnel secondary waterproof joint of a kind of improvement. Comprise GINA waterstop, A type end box hat, Type B end box hat, W type waterstop, GINA waterstop pressing plate, sealing steel disc, W type waterstop pressing plate, threaded stud, compressing tablet. A type end box hat, Type B end box hat and top board (base plate) concrete consolidation, GINA waterstop one section is fixed on Type B end box hat. GINA waterstop pressing plate and A type end box hat connect admittedly, the other end of compacting GINA waterstop. Sealing steel disc embeds in concrete, is connected with A type end box hat and Type B end box hat. Threaded stud is through W type waterstop pressing plate and is fixed, and W type waterstop relies on compressing tablet to be fixed on W waterstop pressing plate.
