Tunnel Formwork

Products Introduction & Application:

● Keep suitable formwork strength, make the vault and side wall be smooth in the secondary lining operation.

● Limitedly analysis and calculate the stress to optimize the structure, which can guarantee the strength and stiffness, and also reduce the steel consumption and construction cost.

● Implement standardization renovation, use standard component, promote its versatility and improve repeated utilization factor.

Features:
①Good concrete quality
With full steel materials, high load bearing capacity and stiffness is achieved, that makes perfect concrete surface.
②High-speed of installation and removal of the form
The formwork is fully hydraulic, with hydraulic cylinder to prop & strip, and lock mechanically.
③Easy operation and safety

Projects:

Q:The tunnel lining is wood, how should support?: Small pipe or large, medium pipe shed is the advanced support for the broken rock area or into, out of the hole, of course, grouting, grouting without losing the significance of the implementation.

Q:I would like to ask the tunnel step method excavation, the height of each step is how to divide?: Tunnel excavation adopts mechanical construction, tunnel excavation using simple self assembling drilling trolley, millisecond detonator, in order to improve the effect of smooth blasting around the eyes, around the eye using special Nonel detonation. Tunnel outlet using muck loader, dump truck with transport ballast. Two tunnel lining concrete use of the length of integral pouring formwork trolley 12M, concrete mixing station in centralized mixing, concrete transport vehicle transport pump into the mold.

Q:I would like to know the safety awareness of the tunnel lining formwork trolley Prawns to help answer oh: No special requirements, not special equipmentFirst of all, it must be the track, the sleeper to the sleeper rail

Q:What is the first project of tunnel constructionNow to do some of the tunnel program, you need to be the first to list out, a total of what? I know that the first branch, two lining, inverted arch, tunnel, pavement these: Summary of construction of the first two tunnel lining

Q:The tunnel has the super big pipe shed and the lead small conduit, is carries on the blasting excavation first or carries on the advance support first, has the anchor rod in the tunnel, this between the construction craft order is any: Closed arch fill concrete pouring pouring arch fill fill arch wall waterproof plate arch wall steel reinforced concrete side wall chisel template trolley in the end of the work of the arch wall two lining concrete

Q:What is the simple calculation method of the tunnel excavation unit price: Fully integrated unit price = labor + material equipment + + + + + + + management fees

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. Thank you

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:How to put the positioning point is based on what is mainly based on my novice, do not: The next two large positioning along the side mode, re positioning of two small side mode along the point, then turn to check the center point and elevation, if not the positioning deviation is complete, then re adjust the positioning deviation! If you have time to measure the location of the site can be set up, then you do not nail this method, the five points directly to the elevation and mileage can be controlled for a long time

Q:Two tunnel lining reinforced concrete template to price behavior can be contracted: There is two times of lining concrete pouring, the normal price is within 100 yuan, this is the pure artificial price, does not contain steel trolley and various materials two tunnel lining.
