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,fully hydraulic.With hydraulic
cylinder to prop & strip, and lock mechanically
◆ High-speed of installation and removal of the form
◆ Easy operation and safety.The empty gantry allows the
transport vehicles to pass.
- Q: The tunnel structure of plastic mould
- Tunnel construction, due to the wall and floor can be cast at the same time, therefore, the design of the building has the following requirements.(1) the width and height of the room should be relatively constant, and the thickness of the bearing wall should be consistent.(2) there are two longitudinal walls inside the corridor, and the upper and lower layers are thick enough to adjust the depth of the rooms on both sides.(3) the thickness of the floor should be kept constant.(4) the basic unit of the structure must be open on one side, and the large span can be opened on both sides.(5) the arrangement should be avoided in the plane.
- Q: How the tunnel template is calculated
- The construction specification requires that the main hole should adopt the full section lining formwork trolley, and the other cars can be connected, the man and the equipment can be assembled.At present, the construction of the tunnel in our country basically uses the steel formwork trolley, many provinces and cities have set the minimum thickness of the template.
- 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: Highway bridge template needs, probably with the thickness of both the construction requirements can be met, and more cost-effective?
- According to the actual situation of your project
- Q: What is the role of the grid steel frame and steel mesh in the power tunnel
- The production of the grid steel frame component production and installation grid steel frame component is suitable for the production of the steel frame of the initial lining and the support of the digging tunnel. The steel grid with steel and steel by welding is composed of steel frame, steel grille by assembling (bolting, welding) after the formation of the steel arch structure after initial support structure of sprayed concrete, which is applied in soft soil tunnel structure is the most effective measure.
- Q: What are the driving jobs in the tunnel
- Outside control traverse 2) elevation control survey 3) in construction traverse
- Q: A detailed method is introduced
- 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: What is the concrete construction of the tunnel invert
- The construction of concrete is related to the non - construction concrete
- Q: When the tunnel fight, there is no provision to fight how many meters left, only by one of the construction
- Electric heating plate can be used for bonding or cold bonding (rubber water seal) or welding (plastic water stop) method, such as user connections are difficult, I can send technical personnel on-site guidance.
- Q: There are no recycling tunnel templates
- If it is a tunnel two lining car template, and the use of the tunnel after the car can continue to use the value of such a tunnel lining car basically has a market of two, but also to be recycled. The specific recovery and continue to use, mainly to see the two lining of the tunnel and the old and new without modification.
