Products Introduction & Application:

● Keep suitable formwork strength, make the vault and side wall be smooth in the secondary lining operation.

● Limitedly analysis and calculate the stress to optimize the structure, which can guarantee the strength and stiffness, and    also reduce the steel consumption and construction cost.

● Implement standardization renovation, use standard component, promote its versatility and improve repeated utilization    factor.


Features:
①Good concrete quality
 With full steel materials, high load bearing capacity and stiffness is achieved, that makes perfect concrete surface.
②High-speed of installation and removal of the form
 The formwork is fully hydraulic, with hydraulic cylinder to prop & strip, and lock mechanically.
③Easy operation and safety


Projects:



Q:12 meters of the tunnel car, under normal circumstances, one of the two months to be able to cast a few models?
According to the normal situation, three days a lining cycle, a month to play at least 9 plates!
Q:1 tunnel lighting design steps, 2 teacher said to design a template, is not to create a tunnel, and then according to the numerical calculation of what?
When the light into the human eye increases, the pupil contraction, when the surrounding environment becomes dark; into the human eye when the light is reduced, the pupil increases.
Q:How many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?
And these kinds of excavation methods need to determine the number of excavated meters according to the grade of surrounding rock. Tunnel invert and floor is completed after the initial support (that is, shotcrete, a layer of concrete, in the excavation of rock on some hard rock without vertical spray arch thin, weak surrounding rock shall be sprayed on the vertical arch thickness in this special project map will show) for pouring 2 reinforced concrete lining when left in general is 6~12 meters
Q:The tunnel lining is wood, how should support?
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:What are the driving jobs in the tunnel
Outside control traverse 2) elevation control survey 3) in construction traverse
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?
Two lining concrete pouring mould capable of self walking
Q:How the tunnel template is calculated
According to the experience and the reuse rate of the template, the thickness of the single lane tunnel template is 10mm, the thickness of the single three lane template is 12mm, and the thickness of the one-way tunnel is 15mm. Consider the length of the template and the construction of the impact of general 10m, not more than 12 meters.
Q:When the tunnel fight, there is no provision to fight how many meters left, only by one of the construction
Fixed strip: the use of additional reinforcement fixation; special fixture fixed; the wire and the fixed template (Figure 2).
Q:I would like to know the safety awareness of the tunnel lining formwork trolley Prawns to help answer oh
Two during the 1 excavation of earthwork calculating boundary line is important??? 2 measuring points as far as the standard
Q:In the tunnel construction, the water stop belt and the water stop strip are respectively used in what place, the construction joint and the subsidence seam many meters set a, above all has any function
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.
