- 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 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: Tunnel two lining car moving outside the template after the demolition of how the car is similar to the nature of the sliding movement and concrete off
- In addition there is a template on the trolley Jack and hydraulic cylinder electric control, can be extended to shrink, when the formwork is to open the template of the trolley, when the contraction of template removal
- 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
