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

According to the actual situation of your project

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

The template is removed, the car generally has a fixed track, easy to move. What do not understand, you can secretly I hope to help you!

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

Summary of construction of the first two tunnel lining

Q:Two tunnel lining reinforced concrete template to price behavior can be contracted

This problem should belong to the industry confidential!If the two lining of the tunnel is pure manual, the normal price is between 800 and 650,

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:Design of lining concrete is C30, what should be used in the construction of concrete arch cushion concrete?

Course (bed) refers to the structural layer below the base level. Its main function is to separate water, drainage, antifreeze in order to improve the working conditions of the base and foundation, and its water stability requirements.

Q:What are the reasons for the two lining concrete lining of the tunnel?

(3) the concrete pump tube, vibration rod and other mechanical repeated impact, workers trample or vibrator touch bar, caused by displacement and deformation of steel exposed.

Q:Would you please tell me the difference between the concrete and shotcrete in the tunnel?

Characteristics of shotcrete:(1) the sprayed concrete has the characteristics of rapid growth, strong bonding force, high density and good impermeability. It can better fill the gap between the rock blocks, increase the integrity of the surrounding rock, prevent the free surface weathering and loosening, and work together with the surrounding rock.(2) the construction of shotcrete will transfer, pouring and tamping a few processes into one, and do not need a template, so the construction of fast, simple.(3) sprayed concrete can play an important role as early as possible.(4) compared with the concrete, the physical and mechanical properties of sprayed concrete are improved.

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:12 meters of the tunnel car, under normal circumstances, one of the two months to be able to cast a few models?

Seven hours after the maintenance of formwork, pouring a every day is no problem, that is to say a month to about fifteen die casting.
