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:

◆ No assembling, easy operation with formed formwork.

◆ High stiffness, make perfect shape for concrete.

◆ Repeatedly turnover is available.

◆ Widely applied range, such as building, bridge, tunnel, etc.

Q:In the tunnel construction, the water stop strip and the water stop strip are used in what place
If you need to connect in the field, you can use the electric heating plate vulcanization bonding or cold bonding (rubber water stop) or welding (plastic water stop) method, such as user connection is difficult, I can send technical personnel on-site guidance.
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: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:How to calculate the lining formwork trolley in tunnel construction
In the construction of the tunnel lining template can belong to the low value consumables in accounting, purchasing back into low value, and share in the future cost of 50%, scrap reamortization into 50% of the cost of this method is of low value consumables 55 amortization method; fixed assets, equipment car belonging to the class the asset depreciation period of 10 years. The lining template trolley for a device, rather than separate accounting, and the template should be turnover materials? Added: I engaged in casting model in the low value consumable, car is of course equipment assets added: template is a collar with the repeated use of the low value consumables, which belongs to the class of tools, you can also be classified as turnover materials, but according to the use of reasonable cost sharing principle after ask: you the manufacture of accounting, and it is in the tunnel construction, the construction enterprise to buy trolley. I personally feel that the template should be separated from the car accounting, so more true and accurate. Thank you
Q:The tunnel lining is wood, how should support?
The excavation of the tunnel face, slag, to the primary support system, first hit the bolt, then use steel or steel made of steel, installation support in tunnel contour, and then sprayed concrete (poor surrounding rock hanging steel mesh, then sprayed fiber concrete).
Q:Tunnel construction sequence What is the sequence of construction process
Closed arch fill concrete pouring pouring arch fill fill arch wall waterproof plate arch wall steel reinforced concrete side wall chisel template trolley in the end of the work of the arch wall two lining concrete
Q:What grade of concrete used for tunnel cushion
The thickness of the cushion should not be less than 70mm, and the concrete strength grade should not be less than C10;
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:Two lining concrete pouring should adopt the combination of steel formwork system and formwork trolley two template system.
Generally, a plurality of arc and straight steel die!Normal lining trolley
Q:When the tunnel fight, there is no provision for the number of meters hit
Fixed strip: the use of additional reinforcement fixation; special fixture fixed; the wire and the fixed template (Figure 2).
