Q:Tunnel lighting design steps, 2 teachers said to design a template
When the light into the human eye increases, the pupil contraction, when the surrounding environment becomes dark; into the human eye when the light is reduced, the pupil increases.
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:When the two lining of the tunnel is used as the lining concrete of the two, how to lay out the trolley
The next two large positioning along the side mode, re positioning of two small side mode along the point, then turn to check the center point and elevation, if not the positioning deviation is complete, then re adjust the positioning deviation! If you have time to measure the location of the site can be set up, then you do not nail this method, the five points directly to the elevation and mileage can be controlled for a long time
Q:The small side wall of the small side wall and inverted arch in the high speed tunnel
The self - made invert sliding formwork trolley is used to fix the side plate directly on the trolley. This is the best way
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:How many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?
6 excavation methods of tunnel1, full section method2 step method3, three steps of the 7 step excavation method4, septal wall method (CD method)5, the intersection of the next door method (CRD method)6, double side drift method
Q:What are the reasons for the two lining concrete lining of the tunnel?
(1) the steel frame is put aside, there is no reinforcement pad or pad number is not enough, the position is not correct, resulting in the reinforcement close to the template and exposed.(2) the coarse aggregate size is greater than the reinforcement spacing, or the debris is placed in the steel frame, while the concrete leakage, forming a serious honeycomb and holes and exposing the reinforcement.
Q:Concrete construction technology of tunnel roof?
Concrete construction technology of tunnel roof:Due to the main roof, the floor of a large amount of concrete pouring, consider the construction period and other factors, the site is equipped with 2 sets of automotive pump or HBT60 pump and 300m Phi pipe and a variety of accessories.
Q:On the interpretation of the specialized words in tunnel
