Building tunnel formwork

Q:What is the vault vault seal and dead seal please give a detailed drawing of the drawing bar do not know how to do?: The hole in the template above people standing on the head of I welded pipe, connected with concrete pump.

Q:The arch and the arch of the tunnel: This part of the tunnel lining is generally the first pouring, pouring formwork trolley can be placed on the inverted arch concrete and support, to the construction of the tunnel arch wall concrete.

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:When the two lining of the tunnel is used as the lining concrete of the two, how to lay the trolley? Please kindly explain steps.: The first measurement group with total station will be five points (template center, 2 large side mode along the point, 2 small side mode along the projection point) in lofting invert, with nails into the inverted arch concrete as a symbol, and note the nail surface elevation. The trolley positioning, the first to the two lining trolley running mileage, and positioning, positioning process will have been completed two off the top two tight lining lining, free end positioning first center point positioning control of elevation and with a plumb line (top surface elevation is equal to the length of the plumb line + if the mileage of two the center point of elevation can be lining)

Q:12 meters of the tunnel car, under normal circumstances, one of the two months to be able to cast a few models?: According to the normal situation, three days a lining cycle, a month to play at least 9 plates!

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 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:What is the width of a ring in a tunnel: Of course, the assembly of the tunnel, such as subway shield tunnel, a ring is the length of the shield segment, there are 1.0m, 1.2m, 1.5m, 2.0m.

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: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)
