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: I would like to ask the tunnel step method excavation, the height of each step is how to divide?
- On the circular arc heading cutting method, the excavation of each cyclicfootage and steel frame with same interval, after the excavation will be used in the initial support, the excavation behind the steps of 8~10m, after the excavation construction of initial support and invert, and then the middle rock pillar grouting reinforcement. (4) of excavation the surrounding rock and the surrounding rock in deep buried section IV and supporting: IV rock by step excavation method, step up the steps behind 8~10m, up and down the steps of primary support construction must follow with the excavation. Rock class take the whole section excavation method. (5) are the simple types of rock excavation self assembling drilling trolley, with dump truck shipment mucking loader. In order to ensure the safety and stability of tunnel construction in soft rock section, the construction must follow the "weak blasting, little disturbance, short excavation, strong support and frequent measurement, tight lining", in the application of The following measures shall be taken
- Q: How the tunnel template is calculated
- The construction specification requires that the main hole should adopt the full section lining formwork trolley, and the other cars can be connected, the man and the equipment can be assembled.At present, the construction of the tunnel in our country basically uses the steel formwork trolley, many provinces and cities have set the minimum thickness of the template.
- 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: The tunnel lining is wood, how should support?
- The excavation of the tunnel face, slag, to the primary support system, first hit the bolt, then use steel or steel made of steel, installation support in tunnel contour, and then sprayed concrete (poor surrounding rock hanging steel mesh, then sprayed fiber concrete).
- 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: Tunnel steel arch behind the steel mesh after a layer of fine iron wire mesh what effect is there?
- 2, ingate construction shaft sealing, to get rid of advanced small pipe grouting reinforced concrete, and supported the upper 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: 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: I would like to know the safety awareness of the tunnel lining formwork trolley Prawns to help answer oh
- Second, check the obstacles before starting, the process of attention to observe at any timeWire, wind
- Q: What is the role of the tunnel formwork trolley? What is the use of template trolley?
- The car is often used in the construction of hydraulic tunnel, the tunnel is not allowed to have concrete construction longitudinal joints, in the hydraulic tunnel span is large
- Q: How to calculate the lining formwork trolley in the tunnel construction, is the fixed assets or the turnover materials?
- 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.
