Building Bridge Tunnel Formwork and scaffolding system

Q: I would like to ask the tunnel step method excavation, the height of each step is how to divide?: Tunnel excavation adopts mechanical construction, tunnel excavation using simple self assembling drilling trolley, millisecond detonator, in order to improve the effect of smooth blasting around the eyes, around the eye using special Nonel detonation. Tunnel outlet using muck loader, dump truck with transport ballast. Two tunnel lining concrete use of the length of integral pouring formwork trolley 12M, concrete mixing station in centralized mixing, concrete transport vehicle transport pump into the mold.

Q: The tunnel structure of plastic mould: In the use of the whole tunnel mode is not as flexible as semi tunnel mode, the lifting equipment requirements are higher, it is gradually being semi tunnelMode substitution.

Q: What is the vault vault seal and dead seal please give a detailed drawing of the drawing bar do not know how to do?: The arch support is an adjustable template or a small template

Q: I would like to ask the tunnel hydraulic trolley steel template design is the use of what software: Tunnel lining trolley design software is CAD, the use of the software for the design of the structure

Q: The tunnel has the super big pipe shed and the lead small conduit, is carries on the blasting excavation first or carries on the advance support first, has the anchor rod in the tunnel, this between the construction craft order is any: Measuring and setting out the drill hole charge blasting, ventilation, smoke exhaust, water spraying and dust removing, the top of the vertical arch, the anchor rod and the reinforcing steel net, the spraying concrete operation enters the next cycle, and the first branch is stabilized and then the two lining is applied

Q: What is the width of a ring in a tunnel: Of course, the assembly of the tunnel, such as subway shield tunnel, a ring is the length of the shield segment, there are 1.0m, 1.2m, 1.5m, 2.0m.

Q: Tunnel two lining car moving outside the template after the demolition of how the car is similar to the nature of the sliding movement and concrete off: No, the car is a mechanical structure, the first car on the template brush oil release agent or diesel oil, to prevent sticking

Q: What is the concrete construction of the tunnel invert: The construction of concrete is related to the non - construction concrete

Q: What is the first project of tunnel constructionNow to do some of the tunnel program, you need to be the first to list out, a total of what? I know that the first branch, two lining, inverted arch, tunnel, pavement these: The first project of concrete lining of this section as I bid the tunnel project, on the next two plays a role model leading lining construction, so the various factors must be considered in detail, before the construction plan, reasonable arrangement, strict control of construction process, construction timely summary, finally reached the first the United States, the project entity information is true and complete, the project finished good target

Q: I would like to ask the high-speed rail tunnel invert small side wall and arch with the small side of the wall of the hanging formwork of what a good method?: Die casting. Install the inverted L hanger on the side wall.
