Building Bridge Tunnel formwork

Q:For example, lining, invert, bias and so on words,, to answer the full thank you: You haven't even touched the tunnel. Simply to say that the lining is the use of concrete or reinforced concrete tunnel inside the template pouring. The author is to stabilize the stability of the rock itself, followed by the tunnel in order to facilitate the application of.

Q:What are the driving jobs in the tunnel: Outside control traverse 2) elevation control survey 3) in construction traverse

Q:The tunnel structure of plastic mould: In the use of the whole tunnel mode is not as flexible as semi tunnel mode, the lifting equipment requirements are higher, it is gradually being semi tunnelMode substitution.

Q:What is the concrete construction of the tunnel invert: The construction of concrete is related to the non - construction concrete

Q:I would like to know the safety awareness of the tunnel lining formwork trolley Prawns to help answer oh: Two during the 1 excavation of earthwork calculating boundary line is important??? 2 measuring points as far as the standard

Q:When the tunnel fight, there is no provision to fight how many meters left, only by one of the construction: Fixed strip: the use of additional reinforcement fixation; special fixture fixed; the wire and the fixed template (Figure 2).

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: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.

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:Ask, general highway tunnel measurement with the total station to measure which aspects? The more detailed the better: The first instrument identification, according to the drawings issued by the tunnel portal design to determine, determine the portal after the slope portal to lofting, tunnel excavation and excavation contour checking (i.e. overexcavation measurement)
