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: Highway bridge template needs, probably with the thickness of both the construction requirements can be met, and more cost-effective?
- Hello, highways, bridges, tunnels, dams, railways and other projects, are generally used in bridge plate 12/15/18MM specifications
- Q: How to put the positioning point is based on what is mainly based on my novice, do not
- 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: What is the role of the tunnel formwork trolley? What is the use of template trolley?
- The use of full circle wear line; side and roof arch lining are most commonly used, two concrete lining construction commonly used in highway, railway tunnel and underground cavern.
- 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: 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
- 5, the user should be based on the order of the project structure, design drawings to calculate the length of the product, the special-shaped structure should have drawings, as far as possible in the factory will be connected to the whole
- Q: What are the steps? If you build a template, how to fill in the concrete. The tunnel is to dig all the generalist pouring, or digging into the side. Simply say. Better picture. In addition, we have seen a video, the shield machine to dig up the tunnel after the installation of a number of prefabricated panels, but these prefabricated plate is curved. Do not have to fill in a semicircle tunnel?
- Pouring should be set up before the template, the concrete template will be about 50mm*50mm of the pouring bin.After the excavation of the shield, the top arch and the top arch of the casting template are separated, so you can see the situation similar to the arc.
- Q: What is the concrete construction of the tunnel invert
- As the name implies, concrete is the concrete that needs to be supportedv
- 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: 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: How many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?
- 6 excavation methods of tunnel1, full section method2 step method3, three steps of the 7 step excavation method4, septal wall method (CD method)5, the intersection of the next door method (CRD method)6, double side drift method
