Q:How to calculate the lining formwork trolley in tunnel construction
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 to arch the arch concrete pouring
Two concrete tunnel lining, template is used according to the size and shape of the tunnel design custom-made, I-beam welded frame, welded steel plate, known as the "two trolley liner" (hydraulic jack lifting and installation of steel wheel moving on the rail), is generally the length of 9~12m, concrete pouring pump concrete.
Q:What is the vault vault seal and seal
The arch support is an adjustable template or a small template
Q:Where is the B-B section of the tunnel invert reinforcement
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:How to put the concrete on the tunnel
Pouring should be set up before the template, the concrete template will be about 50mm*50mm of the pouring bin.After the excavation of the shield, the top arch and the top arch of the casting template are separated, so you can see the situation similar to the arc.
Q:Would you please tell me the difference between the concrete and shotcrete in the tunnel?
These two kinds of concrete construction method is actually the difference.Formwork concrete: after the formwork is good, the concrete is the concrete, such as the tunnel lining, the bridge pier and so on.
Q:Concrete construction technology of tunnel roof?
Concrete construction technology of tunnel roof:Due to the main roof, the floor of a large amount of concrete pouring, consider the construction period and other factors, the site is equipped with 2 sets of automotive pump or HBT60 pump and 300m Phi pipe and a variety of accessories.
Q:Who can give me detailed tunnel construction process
Tunnel construction process, the first branch is a temporary payment, two lining is a permanent support.1, the hole before the edge, the construction of the slope (including drainage, electricity, etc.);2, the construction of large pipe shed3, measurement positioning line;4, drilling, blasting;5, slag, playing anchor, steel, injection (including the initial spray and spray)6, ahead of the anchor (after the pipe section)7, measuring the line;
Q:How many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?
This time you need to see the construction unit of customized templates or make a template for a few meters, such as the 6 template pouring 6 meters, 12 meters is 12 meters, but not more than 12 meters or less than 6 meters, the pouring of inverted arch lining 2, or a concrete filling or the floor, according to your concrete filling or bottom layer below is conducted when a one-time pouring process is only a few meters a few meters. You can take a look at TZ204-2008 "railway tunnel construction technical guide" fifth "construction method" learning
Q:What grade of concrete used for tunnel cushion
Course (bed) refers to the structural layer below the base level. Its main function is to separate water, drainage, antifreeze in order to improve the working conditions of the base and foundation, and its water stability requirements.
