Product Description:

Building 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:

◆ High stiffness, make perfect shape for concrete.

◆ Easy operation, save labor and force.

◆ Fast forming, repeatedly turnover.

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 are the driving jobs in the tunnel
The face, each step, invert, two lining, template positioning surveying
Q:Demolition of tunnel bearing formwork for several days
The removal time of concrete wall and beam column pouring template is determined according to the strength of concrete, different situations: different removal time of concrete strength of the bottom die and the bracket removal should meet the following requirements:
Q:I would like to ask the tunnel step method excavation, the height of each step is how to divide?
Tunnel excavation adopts mechanical construction, tunnel excavation using simple self assembling drilling trolley, millisecond detonator, in order to improve the effect of smooth blasting around the eyes, around the eye using special Nonel detonation. Tunnel outlet using muck loader, dump truck with transport ballast. Two tunnel lining concrete use of the length of integral pouring formwork trolley 12M, concrete mixing station in centralized mixing, concrete transport vehicle transport pump into the mold.
Q:Tunnel construction technology and method
5) the construction of open cut tunnel reinforced concrete structure construction is divided into two parts: first, the construction of inverted arch and wall foundation of reinforced concrete, to be part of the concrete reaches certain strength, stripping, cutting hair construction joints, and construction of the upper side wall and arch of reinforced concrete. The inverted arch and wall part of the composite steel formwork, artificial pouring, side wall and arch concrete construction formwork for the internal mold, and molded with combined steel formwork, formwork and external bracing to ensure stable, symmetrical pouring concrete, steel processing plant in processing molding, binding site. The concrete is produced by the automatic metering concrete mixing station, the concrete transport vehicle transportation, the concrete pump into the mold, the insertion type tamping device is compacted, and the arch wall concrete is completed once.6) water proof construction, laying waterproof layer, tunnel construction on the surface of concrete repair chisel flat uneven place to prevent damage of waterproof board. The weld quality of the waterproof board shall meet the requirements. If there is any defect, corrective action must be taken to meet the requirements.7) arch backfilling: Myeongdong vault above maximum backfill height 2m, compaction degree '93% fill in the top-level clay layer of water, the backfill surface of turf.Back fill both sides of the symmetry at the same time, the bottom of the wall filled with 0.5m ~ 1m thick gravel and compacted, and then the use of artificial layered backfill, layer by layer compaction. Careful protection of the waterproof layer during backfilling is not destroyed.The water layer of clay and the side, the slope of the lap is good, close to prevent surface water leakage.
Q:How to set the location of the tunnel trolley,
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: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:How to fill in the tunnel template
Plane position and elevation meet the design requirements
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 are the safety awareness of the tunnel lining formwork trolley?
Second, check the obstacles before starting, the process of attention to observe at any timeWire, wind
