Q:Highway bridge template needs, probably with the thickness of both the construction requirements can be met, and more cost-effective?

It is best to use the high turnover times, can also be used as the use of the beam die, more cost-effective

Q:Loess tunnel construction quality control points

3) arch filled with rubble concrete should meet the requirements of the relevant regulations.4) concrete or rubble concrete arch above the back should reach the design strength of concrete arch in the back 70% after construction.

Q:Ask, general highway tunnel measurement with the total station to measure which aspects? The more detailed the better

The first instrument identification, according to the drawings issued by the tunnel portal design to determine, determine the portal after the slope portal to lofting, tunnel excavation and excavation contour checking (i.e. overexcavation measurement)

Q:How the tunnel template is calculated

The man's answer is analysis procedure of tunnel structure analysis of finite element modeling.The design of tunnel lining formwork and support must have enough strength, rigidity and stability. The utility model has the advantages of no convex concave, no deviation, no distortion, and the appearance of the concrete is regular and beautiful.

Q:What are the steps? If you build a template, how to fill in the concrete. The tunnel is to dig all the generalist pouring, or digging into the side. Simply say. Better picture. In addition, we have seen a video, the shield machine to dig up the tunnel after the installation of a number of prefabricated panels, but these prefabricated plate is curved. Do not have to fill in a semicircle tunnel?

Tunnel concrete is completed by the way of edge excavation and lining. After the excavation, the shotcrete is used as the initial support, and then the reinforcing steel mesh is set up. Only after the two lining.

Q:The arch and the arch of the tunnel

Tunnel invert refers to the bottom of the tunnel (anti arch, so called inverted arch)

Q:In the process of tunnel construction, two kinds of formwork system should be adopted in the construction of the two lining concrete. Q: what is the template trolley?

Tunnel two lining concrete pouring mould! Template trolley!

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 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?

The pouring of inverted arch and the pouring of the short side wall, do not step in place, install the side die on the invert

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.
