Building Bridge 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.

Bridge Formwork System and scaffolding system

Q: Where is the B-B section of the tunnel invert reinforcement: This part of the tunnel lining is generally the first pouring, pouring formwork trolley can be placed on the inverted arch concrete and support, to the construction of the tunnel arch wall concrete.

Q: What is the vault vault seal and dead seal please give a detailed drawing of the drawing bar do not know how to do?: Directly in the template hole, make a steel plate bolt

Q: Would you please tell me the difference between the concrete and shotcrete in the tunnel?: Jet coagulation: the construction method of spraying fine concrete with spray gun. It is often used to fill the lining of tunnel lining, wall, ceiling and other structures.

Q: Design of lining concrete is C30, what should be used in the construction of concrete arch cushion concrete?: Now the actual project is basically C15, if the economy is less than C15.

Q: When the two lining of the tunnel is used as the lining concrete of the two, how to lay the trolley? Please kindly explain steps.: If the template comparison rules, the design center line directly, that is, the center of the car can be, and then measured elevation and the design elevation of the introduction of the real distance from the real point of the vehicle

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 utility model is mainly composed of a simple lining trolley, a full hydraulic automatic walking lining trolley and a grid type lining trolley. Full hydraulic lining trolley can be divided into the side and roof arch, circular needle beam, bottom mold, full circle needle beam through type etc.. It is also widely used in the construction of hydraulic tunnel and bridge that the lifting sliding mode, the lifting sliding mode and the turning mode, etc..

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: Two tunnel lining reinforced concrete template to price behavior can be contracted: Specific price mainly depends on the length of the tunnel, which is the size of the project, and the geological conditions of tunnel is the tunnel construction is now the price of pure artificial price, the specific price or to the bidding price and the construction unit price guide, after all, the project is now basically is the lowest bid, the inevitable choice to compress all fees is the construction unit.If you need to complete the tunnel labor contract price and the cost of all, you can continue to ask questions, hope to adopt!

Q: I would like to ask the high-speed rail tunnel invert small side wall and arch with the small side of the wall of the hanging formwork of what a good method?: The self - made invert sliding formwork trolley is used to fix the side plate directly on the trolley. This is the best way
