Description
Technical field
The utility model relates to tunnel construction technologies, the in particular to mechanical paving of earth water-proof plate and two lining longitudinal reinforcements
If using tunnel trolley.
Background technique
With the quickening of domestic high-speed rail construction speed, high-speed rail constructing tunnel facility demand sharp increase.In constructing tunnel
Tunnel-liner after the completion of need to carry out waterproof and consolidation process, including be laid with after splash guard carries out waterproof and be laid with two lined steel muscle
It carries out concrete pouring layer and forms second consolidation.Just Zhi Jinguan will be sprayed in tunnel, but the surface after its spraying still has
Rough and uneven in surface phenomenon.To avoid splash guard from being laid on scraggly surface, therefore, between splash guard and spray coating also
Geotextiles need to be set to form cushion.Two lined steel muscle include circumferential reinforcement and longitudinal reinforcement, in the prior art, in splash guard
After the completion of laying, it is first laid with the circumferential reinforcement being relatively large in diameter, re-lays longitudinal reinforcement, to utilize the steel hoop shape being relatively large in diameter
At the supporting member of longitudinal reinforcement, then second layer longitudinal reinforcement and circumferential reinforcement are laid with after the completion of longitudinal reinforcement is laid with, it is this
Paving mode such as presses original artificial paving mode, haves the shortcomings that labor intensity is big.
For high-speed rail tunnel, since running velocity is fast, tunnel cross-section is big.Therefore, it is necessarily required to big specification
The two lined steel muscle that geotextiles and splash guard and length and diameter dramatically increase.In addition, due to high-speed rail design specification and construction rule
Model requirement, two lined steel muscle outsides must have the cement layer protection of setting thickness.But in existing construction method, since reinforcing bar has
Elasticity, circumferential reinforcement both ends are not limited well, are easy to poke splash guard in process of deployment, are influenced waterproof effect；And
And the thickness requirement of cement layer protective layer also cannot be guaranteed.
Although present inventor has carried out larger improvement to these construction technologies before this, and from May, 2017
A series of patent applications are had submitted successively, and solve a large amount of technical problems above-mentioned.But inventor in actual application
It has also been found that needing further to solve the problems, such as.For this purpose, inventor proposes further improved technical solution to the problem of discovery.
Summary of the invention
The purpose of this utility model provides a kind of earth water-proof plate and two linings is longitudinal aiming at the deficiencies in the prior art
Mechanical be laid with of reinforcing bar uses tunnel trolley, which makes flexible drawing component by traction drive and flexible drawing component
