Product Description:

tunel formwork for tunel construction。


Specifications

1 Opening and closing by completely hydraulic system. 
2 Energy saving.


The fully automatic tunnel lining form is a molding equipment once for all for concrete lining of railway and highway tunnels. It is designed and manufactured according to the tunnel’s height and width of its gantry can guarantee the traffic of the rail and railless transport vehicles; the walking of the whole trolley is driven electrically-mechanically; the forms are operated fully hydraulically, the hydraulic cylinder is used for erecting and collecting the forms and then locking mechanically, the space is reserved between the upper part of the trolley rack and the form for the purpose of installing the tunnel ventilating duct, for lining the tunnel containing the gas, the product’s electrical system will be designed and installed according to the explosion-proof specifications for the gas tunnel so as to guarantee safe use.

Q:How to arch the arch concrete pouring
Small pipe or large, medium pipe shed is the advanced support for the broken rock area or into, out of the hole, of course, grouting, grouting without losing the significance of the implementation.
Q:There are no recycling tunnel templates
If you want another company for the recovery of tunnel two lining trolley, the specific type of price and the address of the template of the trolley that would be able to better the template of the trolley recovery, to play its due value template trolley.
Q:Tunnel steel arch behind the steel mesh after a layer of fine iron wire mesh what effect is there?
3, advance small catheter grouting small catheter with diameter of phi 32-50mm steel pipe, the tip of the tube and tube holes for special processing. The first row with drill drilling pipe. Row spacing is 30cm, fan shape, elevation of 5 degrees to about 8 degrees. The length is 2.25m, a single fluid grouting (cement) or double grout (cement water glass slurry). Adjust the grouting pressure according to the soil.
Q:What is the role of the grid steel frame and steel mesh in the power tunnel
Advanced small pipe grouting small catheter with a diameter of 32-50mm steel pipe, the pipe tip and tube holes for special processing. The first row with drill drilling pipe. Row spacing is 30cm, fan shape, elevation of 5 degrees to about 8 degrees. The length is 2.25m, a single fluid grouting (cement) or double grout (cement water glass slurry). Adjust the grouting pressure according to the soil.
Q:Tunnel construction technology and method
The construction methods and technical measures2.1 construction processTo measure the slope, slope protection, Boulder rolling, processing or drainage construction, earthwork excavation, slope protection, inverted arch and side wall foundation construction, liming cave mould, steel banding, liming mould, pouring concrete, concrete outside the health to release, waterproof layer construction, backfilling and protection engineering construction.2.2 construction methods1) Myongdong and a complete portal excavation, excavation with full width transverse dredging method once formed, the first slopes, put the line before the excavation, then drain.2) with earthwork excavating, the small rock blasting method, drill hole, millisecond electric detonator, mucking loaders, dump truck transport, blasting near the slopes, with smooth blasting, in order to ensure the stability of slope. Excavation from top to bottom, side of the construction side slope excavation and slope into the face of the protection works.3) the first tunnel excavation after 10 ~ 20m, and then open cut tunnel lining. When construction, pay attention to Myeongdong and at the joint of the dark hole, from the inside out.4, before entering the cave, complete all slope reinforcement and protection measures.
Q:How to set the location of the tunnel trolley,
The trolley positioning, the first to the two lining trolley running mileage, and positioning, positioning process will have been completed two off the top two tight lining lining, free end positioning first center point positioning control of elevation and with a plumb line (top surface elevation is equal to the length of the plumb line + if the mileage of two the center point of elevation can be lining),
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).
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:What is the specific structure of the tunnel model
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: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!
