Building Bridge 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: Where is the B-B section of the tunnel invert reinforcement
- This part of the tunnel lining is generally the first pouring, pouring formwork trolley can be placed on the inverted arch concrete and support, to the construction of the tunnel arch wall concrete.
- Q: The periphery of the tunnel outline has been sealed with steel seal, and can be used as the external formwork when the concrete is poured. The 3 parts of the tunnel are divided into floor, side wall and roof. When pouring, the concrete can only be pumped in the tunnel, the outside of the tunnel is the Pearl River, and the construction can not be carried out outside the tunnel. The roof pouring, only from the bottom to the pump. Question: 1, the roof concrete pouring, how to discharge the air? How to tamper? 2, the tunnel width of 23 meters, you need to do the construction of the seam or after pouring it? Time is pressing, please reply as soon as possible. Good addition score. Thank you。 If you can't see the picture, click this link:
- Before pumping concrete, the water in the storage hopper is pumped out of the pipeline to achieve the purpose of wetting and cleaning pipes. And then added to the cement mortar and concrete mix proportion in the hopper (or 1:2 cement mortar), lubricating pipe can start pumping concrete; start pumping, pumping speed slow, hydraulic pressure in the acceptable range, to be pumping well, only with the normal speed of pump. Concrete pumping concrete for continuous operation, if not timely, need to reduce the pump speed, the pump is temporarily interrupted, don't stop stirring; pumping finished cleaning pipes, using air compressor driven cleaning ball, and then immediately wash the concrete pump and pipeline, pipeline disassembled according to different specifications of classification.
- 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: I would like to know the safety awareness of the tunnel lining formwork trolley Prawns to help answer oh
- No special requirements, not special equipmentFirst of all, it must be the track, the sleeper to the sleeper rail
- Q: What is the width of a ring in a tunnel
- Generally used in the tunnel as a two car lining template
- 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: In the tunnel construction, the water stop belt and the water stop strip are respectively used in what place, the construction joint and the subsidence seam many meters set a, above all has any function
- 5, the user should be based on the order of the project structure, design drawings to calculate the length of the product, the special-shaped structure should have drawings, as far as possible in the factory will be connected to the whole
- Q: What are the steps? If you build a template, how to fill in the concrete. The tunnel is to dig all the generalist pouring, or digging into the side. Simply say. Better picture. In addition, we have seen a video, the shield machine to dig up the tunnel after the installation of a number of prefabricated panels, but these prefabricated plate is curved. Do not have to fill in a semicircle tunnel?
- Two lining trolley consists of two parts, one is the erection and welding of steel trolley, and the other is pouring trolley.
- Q: When the tunnel fight, there is no provision to fight how many meters left, only by one of the construction
- Fixed strip: the use of additional reinforcement fixation; special fixture fixed; the wire and the fixed template (Figure 2).
