Product Description:

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:

◆ High stiffness, make perfect shape for concrete.

◆ Easy operation, save labor and force.

◆ Fast forming, repeatedly turnover.

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:Main diseases and prevention of tunnel
Tunnel shotcretePhenomenon: the concrete spray layer and the rock surface is not bonded, concrete spray layer between the bond is not good.Cause analysis: the loose rock not clear spray surface; shotcreted rock debris is not scum washing or flushing thoroughly with wind pressure, water pressure; surface by spraying water, water, water concentration of untreated concrete spraying interval; before a layer of spray surface without wind, water washing scum. The air pressure is inconsistent with the spray distance.Preventive measures: remove the loose rock, clear surface by spraying of water, slag floating debris; water, concentrated water point of the surface by spraying with gouge, guide the drainage treatment of buried pipe; sprayed concrete before spray test, to determine the wind and spray distance coordination relationship between.
Q:The small side wall of the small side wall and inverted arch in the high speed tunnel
The self - made invert sliding formwork trolley is used to fix the side plate directly on the trolley. This is the best way
Q:How to remove the template of the two lining trolley moving outside the tunnel
No, the car is a mechanical structure, the first car on the template brush oil release agent or diesel oil, to prevent sticking
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:The arch and the arch of the tunnel
Tunnel arch wall refers to both sides of the tunnel wall and the top of the arch, the tunnel arch wall is generally the use of a template trolley.
Q:Tunnel lighting design steps, 2 teachers said to design a template
Hope to help you. If the human eye to adapt to different levels of illumination, the need to go through three processes, namely, changes in the size of the pupil, nervous system adaptation, cone and rod cells of the photochemical adaptation of pigment.
Q:I would like to ask the tunnel hydraulic trolley steel template design is the use of what software
You are talking about the design of the tunnel two lining car software.
Q:What is the role of the grid steel frame and steel mesh in the power tunnel
The back cover, shaft ingate construction, to get rid of the upper advanced small pipe grouting reinforced concrete, erecting of ingate upper grille steel frame, injection, get rid of the upper concrete lower reinforced concrete, erecting of ingate to spray the concrete lower grille steel frame.
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
