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:On the measurement of total station
Steel arch support and Lifang line checking, bottom excavation and invert excavation, lining template checking and lofting, invert pavement template checking, reinforced lofting and lining ditch school inspection, line and template checking
Q:Tunnel steel arch behind the steel mesh after a layer of fine iron wire mesh what effect is there?
3, advance small catheter grouting small catheter with diameter of phi 32-50mm steel pipe, the tip of the tube and tube holes for special processing. The first row with drill drilling pipe. Row spacing is 30cm, fan shape, elevation of 5 degrees to about 8 degrees. The length is 2.25m, a single fluid grouting (cement) or double grout (cement water glass slurry). Adjust the grouting pressure according to the soil.
Q:What grade of concrete used for tunnel cushion
Now the actual project is basically C15, if the economy is less than C15.
Q:What is the role of the grid steel frame and steel mesh in the power tunnel
The production of the grid steel frame component production and installation grid steel frame component is suitable for the production of the steel frame of the initial lining and the support of the digging tunnel. 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 are the reasons for the two lining concrete lining of the tunnel?
(3) the concrete pump tube, vibration rod and other mechanical repeated impact, workers trample or vibrator touch bar, caused by displacement and deformation of steel exposed.
Q:What is the simple calculation method of the tunnel excavation unit price
Comprehensive unit price = labor cost + material equipment fee + mechanical + management fee + profit
Q:How to put the concrete on the tunnel
Tunnel concrete is completed by the way of edge excavation and lining. After the excavation, the shotcrete is used as the initial support, and then the reinforcing steel mesh is set up. Only after the two lining.
Q:When the two lining of the tunnel is used as the lining concrete of the two, how to lay out the trolley
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: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.
Q:Two lining concrete pouring should adopt the combination of steel formwork system and formwork trolley two template system.
Generally, a plurality of arc and straight steel die!Normal lining trolley
