Product Description:

Building Tunnel Formwork

A compositional steel formwork system mainly used in the building which has regular structure

without beams, the excellent formwork system can make the integral pouring for the wall & slab

easily achieved.


Characteristics:

◆ High stiffness, make perfect shape for concrete.

◆ Easy operation, save labor and force.

◆ Fast forming, repeatedly turnover.

Q:How to fill in the tunnel template
The template is firm and smooth, there is no error, such as leakage
Q:What is the vault vault seal and seal
Directly in the template hole, make a steel plate bolt
Q:Two tunnel lining reinforced concrete template to price behavior can be contracted
Specific price mainly depends on the length of the tunnel, which is the size of the project, and the geological conditions of tunnel is the tunnel construction is now the price of pure artificial price, the specific price or to the bidding price and the construction unit price guide, after all, the project is now basically is the lowest bid, the inevitable choice to compress all fees is the construction unit.If you need to complete the tunnel labor contract price and the cost of all, you can continue to ask questions, hope to adopt!
Q:Tunnel construction procedure A cycle of steps
Excavation and support of shallow buried and broken section of V grade surrounding rock of portalHole wayThe thin covering layer, poor geological conditions, when the depth of excavation to the arch line, first into the hole wall and the guide pipe shed, the open cut tunnel lining after the completion of the long pipe shed is overlapped on the Dong, to form a fixed end of pipe roof support, opening into the inner wall in the protection of pipe roof under the heading of the two side wall to stagger the footage before and after (5 ~ 10m). If there is a small spacing must also be set prestressed anchor.
Q:What is the role of the tunnel formwork trolley? What is the use of template trolley?
The car is often used in the construction of hydraulic tunnel, the tunnel is not allowed to have concrete construction longitudinal joints, in the hydraulic tunnel span is large
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:Demolition of tunnel bearing formwork for several days
With the temperature, the need for concrete strength of 100% to remove the template
Q:How to design the general layout of the tunnel construction organization design
The location and sketch map of explosive storehouse, spoil yard, office location, living area, entertainment area, temporary drainage ditch.
Q:How to remove the template of the two lining trolley moving outside the tunnel
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 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.
