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: 1 tunnel lighting design steps, 2 teacher said to design a template, is not to create a tunnel, and then according to the numerical calculation of what?
- The pupil is 5 times as fast as the increases, which makes the dark adaptation time to defend much longer. Cone cells can produce or reduce pigment in 10 ~ 12min, and the rod cells are almost 60min need to produce all of the pigment, which makes it very difficult for people to adapt to a very dark environment. How long does it take, depending on the extent of illumination.
- 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: 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?
- Course (bed) refers to the structural layer below the base level. Its main function is to separate water, drainage, antifreeze in order to improve the working conditions of the base and foundation, and its water stability requirements.
- Q: What is the width of a ring in a tunnel
- The car is generally long 9m can be a one-time pouring, a ring is a pouring two lining length
- 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: Tunnel two lining car moving outside the template after the demolition of how the car is similar to the nature of the sliding movement and concrete off
- No, the car is a mechanical structure, the first car on the template brush oil release agent or diesel oil, to prevent sticking
- Q: Two tunnel lining reinforced concrete template to price behavior can be contracted
- This problem should belong to the industry confidential!If the two lining of the tunnel is pure manual, the normal price is between 800 and 650,
- 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.
- Q: How many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?
- This time you need to see the construction unit of customized templates or make a template for a few meters, such as the 6 template pouring 6 meters, 12 meters is 12 meters, but not more than 12 meters or less than 6 meters, the pouring of inverted arch lining 2, or a concrete filling or the floor, according to your concrete filling or bottom layer below is conducted when a one-time pouring process is only a few meters a few meters. You can take a look at TZ204-2008 "railway tunnel construction technical guide" fifth "construction method" learning
