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:
◆ 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: I would like to ask the tunnel step method excavation, the height of each step is how to divide?
- The side ditch construction using composite steel formwork. (1) the temporary facilities of tunnel construction plan layout: in the single ended due to tunnel entrance, temporary facilities of tunnel construction in tunnel exit to the right. The layout for the layout of wind mechanical equipment in the right side of the roadbed export based on the terrain conditions, reservoir located in the left side from the position of about 80m. In the mechanical approach immediately after the entrance of earth excavation construction, roof slope and drainage ditches slope anchor slope reinforcement, well hole digging for. (2): the excavation and reinforcement the mechanical construction, according to the construction method of Subgrade Earthwork excavation, dig to the rock when, in order to minimize the disturbance of the entrance slope and subgrade slope, must adopt the method of weak blasting and presplitting blasting for excavation. The entrance slope using hang net shotcrete reinforcement, to facilitate the safety hole (3). The excavation and support of the shallow section of the surrounding rock of the cave: the construction method adopts the step method, and the advanced grouting bolt is adopted on the stage
- Q: Ask, general highway tunnel measurement with the total station to measure which aspects? The more detailed the better
- Steel arch support and Lifang line checking, bottom excavation and invert excavation, lining template checking and lofting, invert pavement template checking, reinforced lofting and lining ditch school inspection, line and template checking
- Q: How the arch of the tunnel concrete pouring up, how to support before pouring, using I-beam is directly support the earth?
- Small pipe or large, medium pipe shed is the advanced support for the broken rock area or into, out of the hole, of course, grouting, grouting without losing the significance of the implementation.
- Q: The tunnel has the super big pipe shed and the lead small conduit, is carries on the blasting excavation first or carries on the advance support first, has the anchor rod in the tunnel, this between the construction craft order is any
- Measuring and setting out the drill hole charge blasting, ventilation, smoke exhaust, water spraying and dust removing, the top of the vertical arch, the anchor rod and the reinforcing steel net, the spraying concrete operation enters the next cycle, and the first branch is stabilized and then the two lining is applied
- Q: What are the reasons for the two lining concrete lining of the tunnel?
- (4) improper concrete mix, segregation, depending on the template part of the lack of slurry or template serious leakage;(5) no watering wood template wet, water bonding or early form removal, Chaimo missing edge off angle, resulting in reinforcement.
- Q: I would like to know the safety awareness of the tunnel lining formwork trolley Prawns to help answer oh
- Second, check the obstacles before starting, the process of attention to observe at any timeWire, wind
- Q: What is the role of the tunnel formwork trolley? What is the use of template trolley?
- The utility model is mainly composed of a simple lining trolley, a full hydraulic automatic walking lining trolley and a grid type lining trolley. Full hydraulic lining trolley can be divided into the side and roof arch, circular needle beam, bottom mold, full circle needle beam through type etc.. It is also widely used in the construction of hydraulic tunnel and bridge that the lifting sliding mode, the lifting sliding mode and the turning mode, etc..
- 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: What is the simple calculation method of the tunnel excavation unit price
- Parameter valuationThe valuation of parameter method is the method of calculating the multiplication coefficient according to a certain cardinal number or the custom formula. This method is simple and clear, but the biggest difficulty is the scientific formula, accuracy is difficult to grasp. This method is mainly applicable to the construction process must occur, but it is difficult to predict the specific items in the bidding, but can not separate the project content of the project measures. If the valuation night construction fees, two handling fee, rain during construction can be used in this method.
- 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
