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:Who can give me detailed tunnel construction process
In addition, after blasting excavation contour line must be used with artificial picks excavation, fill hole hole blasting is prohibited, should use the diamond, completes the construction of temporary drainage hole, the pump discharge hole, quartz, mica schist will accelerate the loss of self stability in water immersion, and will accelerate the development of the formation of rock joints, if the groundwater pressure too much damage to increase support.
Q:Tunnel steel arch behind the steel mesh after a layer of fine iron wire mesh what effect is there?
4, the production and installation of the grid steel frame components of the steel truss structure for the production of the tunnel excavation of the initial support of the steel frame. The steel grid with steel and steel by welding is composed of steel frame, steel grille by assembling (bolting, welding) after the formation of the steel arch structure after initial support structure of sprayed concrete, which is applied in soft soil tunnel structure is the most effective measure.
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: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:When the two lining of the tunnel is used as the lining concrete of the two, how to lay out the trolley
The next two large positioning along the side mode, re positioning of two small side mode along the point, then turn to check the center point and elevation, if not the positioning deviation is complete, then re adjust the positioning deviation! If you have time to measure the location of the site can be set up, then you do not nail this method, the five points directly to the elevation and mileage can be controlled for a long time
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 for the number of meters hit
Electric heating plate can be used for bonding or cold bonding (rubber water seal) or welding (plastic water stop) method, such as user connections are difficult, I can send technical personnel on-site guidance.
Q:The small side wall of the small side wall and inverted arch in the high speed tunnel
The pouring of inverted arch and the pouring of the short side wall, do not step in place, install the side die on the invert
Q:I would like to ask the tunnel hydraulic trolley steel template design is the use of what software
According to the design requirements, draw the spare parts drawings, and then workers in accordance with the production drawings!
Q:Two lining concrete pouring should adopt the combination of steel formwork system and formwork trolley two template system.
Tunnel two lining concrete pouring mould! Template trolley!
