Product Description:

TUNNEL FORMWORK

The automatic hydraulic tunnel formwork is the equipment to make
the concrete lining for the tunnel in one time.The empty gantry allows the
transport vehicles to pass. The motor gearbox is adopted to drive
the whole equipment, the formwork is fully hydraulic, with hydraulic
cylinder to prop & strip, and lock mechanically

◆  Good concreting quality

◆  High-speed of installation and removal of the form

◆  Easy operation and safety

Q:Loess tunnel construction quality control points
2) the invert, invert the filling layer and dry concrete construction should be concrete accurately, use the template, mechanical tamping compaction. The inverted arch concrete by pumping casting, should use the arch template ensure molding size meets design requirements. The construction of invert arch and filling layer should be completed according to the design of inverted arch concrete construction, the appropriate interval, and then change the proportion of concrete, filling layer of concrete construction;The construction of inverted arch and the cracks and deformation joints should be waterproof treatment according to design requirements, should be in accordance with the relevant provisions of this guide.Invert the overbreak in the allowable range, should be used with the same strength grade of concrete lining casting; overbreak exceeds, should according to the requirements of design and specification of the backfill, shall not use the random hole slag backfill, non intrusive rubble arch section.
Q:What is the role of the grid steel frame and steel mesh in the power tunnel
Function as follows:1, the construction of the shaft excavation of the power tunnel shaft structure is a permanent structure, the construction of the shaft using shotcrete + net structure steel frame + steel mesh support + waterproof film + cast-in-place reinforced concrete lining method.
Q:Tunnel lighting design steps, 2 teachers said to design a template
Hope to help you. If the human eye to adapt to different levels of illumination, the need to go through three processes, namely, changes in the size of the pupil, nervous system adaptation, cone and rod cells of the photochemical adaptation of pigment.
Q:What is the simple calculation method of the tunnel excavation unit price
Comprehensive unit price methodAs the calculation method of this method and the project of comprehensive unit price, is calculated according to the real need of engineering cost measures the amount of consumption and real price, applicable to the calculation of the amount of engineering projects, mainly refers to the number of entities are closely linked and engineering projects, such as concrete formwork, scaffolding, vertical transportation etc.. Different from the sub project, it is not required that the comprehensive unit price of each measure must include the labor cost, material cost, mechanical cost, management fee and profit.
Q:What is the first project of tunnel construction
YK24 + 300 ~ YK24 + + 288 as the first project of the tunnel engineering. There are many factors that affect the quality of the two lining construction, each link in the construction process must be strictly in accordance with the construction specifications
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.
Q:Demolition of tunnel bearing formwork for several days
The average temperature of 20 degrees, can be removed for 28 days. High temperature removal time is short, low temperature stripping time longer.
Q:I would like to ask the tunnel hydraulic trolley steel template design is the use of what software
According to the design requirements, draw the spare parts drawings, and then workers in accordance with the production drawings!
Q:On the interpretation of the specialized words in tunnel
Bias: refers to the formation of the tunnel, resulting in uneven pressure. To provide you with a few books you go to see the explanation. The site is easy to understand.
Q:Two lining concrete pouring should adopt the combination of steel formwork system and formwork trolley two template system.
Tunnel two lining concrete pouring mould! Template trolley!
