Building Bridge&Tunnel Formwork:

A compositional steel formwork system mainly used in the building which has regular structure

without beams, the excellent formwork system can make the integral pouring for the wall & slab

easily achieved.


Characteristics:

◆ No assembling, easy operation with formed formwork.

◆ High stiffness, make perfect shape for concrete.

◆ Repeatedly turnover is available.

◆ Widely applied range, such as building, bridge, tunnel, etc.

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:When the two lining of the tunnel is used as the lining concrete of the two, how to lay out the trolley
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:Loess tunnel construction quality control points
3) arch filled with rubble concrete should meet the requirements of the relevant regulations.4) concrete or rubble concrete arch above the back should reach the design strength of concrete arch in the back 70% after construction.
Q:What is the concrete construction of the tunnel invert
As the name implies, concrete is the concrete that needs to be supportedv
Q:12 meters of the tunnel car, under normal circumstances, one of the two months to be able to cast a few models?
Seven hours after the maintenance of formwork, pouring a every day is no problem, that is to say a month to about fifteen die casting.
Q:What is the specific structure of the tunnel model
The tunnel model is a kind of tool form template which is used for pouring concrete wall and floor at the same time.Total tunnel mode tunnel mode and half tunnel mode two, the basic unit of the tunnel mode is a complete tunnel template, half tunnel is composed of a plurality of unit angle die, and then use the 2.5 tunnel mode to fight and become a complete tunnel mode.
Q:Tunnel lighting design steps, 2 teachers said to design a template
When the light into the human eye increases, the pupil contraction, when the surrounding environment becomes dark; into the human eye when the light is reduced, the pupil increases.
Q:How to remove the template of the two lining trolley moving outside the tunnel
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:I would like to ask the tunnel step method excavation, the height of each step is how to divide?
The side ditch construction using composite steel formwork. (1) the temporary facilities of tunnel construction plan layout: in the single ended due to tunnel entrance, temporary facilities of tunnel construction in tunnel exit to the right. The layout for the layout of wind mechanical equipment in the right side of the roadbed export based on the terrain conditions, reservoir located in the left side from the position of about 80m. In the mechanical approach immediately after the entrance of earth excavation construction, roof slope and drainage ditches slope anchor slope reinforcement, well hole digging for. (2): the excavation and reinforcement the mechanical construction, according to the construction method of Subgrade Earthwork excavation, dig to the rock when, in order to minimize the disturbance of the entrance slope and subgrade slope, must adopt the method of weak blasting and presplitting blasting for excavation. The entrance slope using hang net shotcrete reinforcement, to facilitate the safety hole (3). The excavation and support of the shallow section of the surrounding rock of the cave: the construction method adopts the step method, and the advanced grouting bolt is adopted on the stage
Q:What are the reasons for the two lining concrete lining of the tunnel?
(1) the steel frame is put aside, there is no reinforcement pad or pad number is not enough, the position is not correct, resulting in the reinforcement close to the template and exposed.(2) the coarse aggregate size is greater than the reinforcement spacing, or the debris is placed in the steel frame, while the concrete leakage, forming a serious honeycomb and holes and exposing the reinforcement.
