Embodiment

[0056] Embodiment: The paving process of the tunnel 27 geotextile waterproof cloth and the second lining steel bar 26 in this plan uses the geotextile waterproof cloth and the second lining steel bar 26 to lay the integrated platform 1, including the platform 1, which is used for hoisting and laying The arc-shaped container mechanism of the hoop steel bar 26, the arc-shaped slide rail 8 mechanism 4 for hoisting the longitudinal steel bar and laying waterproof cloth and geotextile, and the ejection mechanism for ejecting the hoop-to-steel bar 26.

[0057] The bottom of the stand 1 is equipped with a traveling mechanism 6, and track steel is installed under the traveling mechanism 6. The traveling mechanism 6 is driven by the motor 23 to realize the walking of the stand 1 on the track. A first hinge is welded on the excavation side of the platform 1 near the tunnel 27 , and the first hinge is located at the bottom of the platform 1 . The platform of platform 1 is longitudinally...

Abstract

The invention belongs to the field of tunnel secondary lining laying and relates to a secondary lining laying process ensuring the secondary lining strength, in particular to a tunnel geotextile, waterproof cloth and secondary lining steel bar laying process. The secondary lining strength is ensured by ensuring the thickness of a concrete protective layer.

Description

technical field [0001] The invention belongs to the field of tunnel secondary lining paving, in particular to a secondary lining paving process ensuring the strength of the secondary lining. Background technique [0002] In China's tunnel engineering construction, the precise positioning of the secondary lining reinforcement binding has always been a major problem that restricts the construction quality of the secondary lining. [0003] In the prior art, the binding of secondary lining steel bars is generally carried out with the help of a platform. The existing platform structure is very simple, and its function is only a movable scaffold. The steel bar binding is mainly done manually, and the steel bar welded on the ground (generally 22-25mm in diameter) is sent from the side of the platform to the arch, and the steel bar is formed into an arc shape on the outside of the platform by using the elasticity of the steel bar itself. And because the steel bars are elastic, the ...
