Product Description:

TUNNEL FORMWORK

The automatic hydraulic tunnel formwork is the equipment to make
the concrete lining for the tunnel in one time.The empty gantry allows the
transport vehicles to pass. The motor gearbox is adopted to drive
the whole equipment, the formwork is fully hydraulic, with hydraulic
cylinder to prop & strip, and lock mechanically

◆  Good concreting quality

◆  High-speed of installation and removal of the form

◆  Easy operation and safety

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:In the tunnel construction, the water stop strip and the water stop strip are used in what place
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.
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: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: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: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
Q:Main diseases and prevention of tunnel
Main diseases and prevention of tunnel1 over excavation in tunnel excavationPhenomenon: in tunnel excavation, the upper, lower, left and right contours are exceeded.The reason analysis: the measurement is not allowed, the deviation is big; the hole position deviation is bigger; the hole in the hole drilling process does not have the straight hole to have the slanting hole to exceed the limit; the blasting parameter choice is wrong, the charge quantity is too much or unreasonable.Preventive measures: to ensure the measurement work turnover review system; accurate calculation of blasting parameters, the formal process test before entering the tunnel, timely adjust the parameters change of geological condition; hole position and direction control in drilling process.
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: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: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.
