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: 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: 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 vault vault seal and dead seal please give a detailed drawing of the drawing bar do not know how to do?
- Directly in the template hole, make a steel plate bolt
- Q: How to put the positioning point is based on what is mainly based on my novice, do not
- 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: The tunnel lining is wood, how should support?
- The excavation of the tunnel face, slag, to the primary support system, first hit the bolt, then use steel or steel made of steel, installation support in tunnel contour, and then sprayed concrete (poor surrounding rock hanging steel mesh, then sprayed fiber concrete).
- 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: What is the role of the tunnel formwork trolley? What is the use of template trolley?
- The use of full circle wear line; side and roof arch lining are most commonly used, two concrete lining construction commonly used in highway, railway tunnel and underground cavern.
- Q: A detailed method is introduced
- 1 overall construction planUsing the new Austrian tunneling method, the construction principle is "less disturbance, early spray anchor, ground measurement, tight closure". The rock excavation method of construction; rock class micro bench excavation, pre splitting blasting; IV surrounding rock by construction method (Section IV surrounding rock under the partial, the construction step method), smooth blasting technique; fault fracture zone by middle wall construction method.The ballast is unloaded by the side unloading loader.Two lining the rail trolley, concrete mixing truck to transport concrete, pumping concrete, lining after decoration engineering construction.It is necessary to strengthen the geological prediction in the fault fracture zone and water rich zone, and provide the basis for the construction.
- 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: In the process of tunnel construction, two kinds of formwork system should be adopted in the construction of the two lining concrete. Q: what is the template trolley?
- Generally, a plurality of arc and straight steel die!Normal lining trolley
