Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention will be further described:

[0024] Such as figure 1 , figure 2 and image 3 As shown, the tunnel secondary lining vault pouring construction device includes a flexible pipeline 1 , a pipeline retractable mechanism 2 and a pipeline conveying mechanism 3 . The pipeline delivery mechanism 3 includes a first guide wheel 301, a second guide wheel 302, and a third guide wheel 303. The second guide wheel 302 and the third guide wheel 303 are located on the same side of the flexible pipeline 1, and the first guide wheel 301 is located on the same side of the flexible pipeline 1. The other side of the flexible pipeline 1 is distributed on the three vertices of the triangle with the second guide wheel 302 and the third guide wheel 303 , and the three guide wheels all have grooves for accommodating the flexible pipeline 1 . The first guide wheel 301 is connected with the driven gear 304, the first hydraulic...

Abstract

The invention discloses a pouring construction device for a vault of a secondary lining of a tunnel and a corresponding construction method. The device comprises a flexible pipeline, a pipeline conveying mechanism and a pipeline retracting and releasing mechanism, wherein the pipeline conveying mechanism comprises a first guide wheel and a second guide wheel, the flexible pipeline is driven by thefirst guide wheel and the second guide wheel to move, and the pipeline retracting and releasing mechanism comprises a coiling block, can be coiled by the coiling block and can penetrate from the sidesurface of the coiling block with a steel pipeline connected to the flexible pipeline. By carrying out vault pouring by employing the device, concrete is poured to the vault from top to bottom, so that a jet grouting mode from bottom to top is avoided, generation of cavities, cracks and the like is reduced advantageously, and the pouring construction quality is improved.

Description

technical field [0001] The invention relates to a tunnel construction device and method, in particular to a construction device and construction method for vault pouring of secondary lining of tunnels. Background technique [0002] The secondary lining of the tunnel is relative to the initial support. It refers to the inner lining built with reinforced concrete and other materials under the condition of the initial support in the tunnel construction, so as to achieve reinforcement support, optimize the route waterproof and drainage system, Beautify the appearance and facilitate the setting of communication, lighting, monitoring and other facilities. In the secondary lining construction, the steel mesh is erected on the basis of the initial support, and then the arched formwork is supported, and then the concrete mortar is injected into the steel mesh outside the formwork layer by layer from the window on the formwork. Concrete mortar gradually rises from both sides of the a...
