Single-side Bracket：
During single-sided concreting, the concrete pressure is transferred into the sub-structure by
means of the single-side bracket.
Characteristics:
◆ For concrete heights up to 8.0m and a fresh concrete pressure up to a maximum of 60KN/m2.
◆ Good standard performance and versatility.
◆ Fast element coupling, all units can be quickly connected.
◆ The finished wall is excellent and absolutely waterproof.
◆ Optimized sizes for transportation.
Design Principle:
There is no wall-through tie-rod in the single-side bracket system. The whole system is adjusted by
the anchor system and the regulator system.
The stress situation from the sketch above.F1 can resist the side pressure of the concrete and F2
can resist the rising force. R can not only bear the gravity force of the bracket, but also the side
pressure of the concrete. This stress system is simple, reasonable and also with convenience and
high safety.
- Q: Where is the B-B section of the tunnel invert reinforcement
- Tunnel arch wall refers to both sides of the tunnel wall and the top of the arch, the tunnel arch wall is generally the use of a template trolley.
- Q: How the tunnel template is calculated
- The man's answer is analysis procedure of tunnel structure analysis of finite element modeling.The design of tunnel lining formwork and support must have enough strength, rigidity and stability. The utility model has the advantages of no convex concave, no deviation, no distortion, and the appearance of the concrete is regular and beautiful.
- Q: Would you please tell me the difference between the concrete and shotcrete in the tunnel?
- Characteristics of shotcrete:(1) the sprayed concrete has the characteristics of rapid growth, strong bonding force, high density and good impermeability. It can better fill the gap between the rock blocks, increase the integrity of the surrounding rock, prevent the free surface weathering and loosening, and work together with the surrounding rock.(2) the construction of shotcrete will transfer, pouring and tamping a few processes into one, and do not need a template, so the construction of fast, simple.(3) sprayed concrete can play an important role as early as possible.(4) compared with the concrete, the physical and mechanical properties of sprayed concrete are improved.
- Q: I would like to ask the tunnel hydraulic trolley steel template design is the use of what software
- Tunnel lining trolley design software is CAD, the use of the software for the design of the structure
- Q: Who can give me detailed tunnel construction process
- On the inner side wall heading section is advanced, the footage was 0.7m immediately on the rock surface at the beginning of the spray, install the first layer of rock along Phi 8 steel mesh, and connected into a whole, set up active and temporary supporting steel arch, and the arch and a connected whole Phi 25 steel, drilling into the phi 25 hollow bolt and grouting, the installation of second layer steel mesh shotcrete layer to design contour line, pay attention to every compact trusses on the back of the footage, about 5~10m after the excavation under the heading section, and the lateral wall of drift can also present a ring section excavation footage was about 20 ~ 35m, support the arch excavation core soil upper arc heading, 3 ~ 5 after excavation footage and central support, under the section of tunnel bottom and the lower end of the previous about heading completely combined with closed loop, is divided into seven excavation, all operations must strictly follow the open Step by step, must be two inside the wall first, follow up the process step by step process. At the same time there must be monitoring data as the basis, redistribution of stress or conversion, will increase the support displacement, and strata subsidence and deformation, should strengthen the monitoring capacity before and after removal of the tunnel deformation and supporting force measurement,
- Q: Design of lining concrete is C30, what should be used in the construction of concrete arch cushion concrete?
- The thickness of the cushion should not be less than 70mm, and the concrete strength grade should not be less than C10;
- 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: What is the simple calculation method of the tunnel excavation unit price
- Fully integrated unit price = labor + material equipment + + + + + + + management fees
- 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: 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
