High-end Tunnel Formwork

Q:What is the vault vault seal and dead seal please give a detailed drawing of the drawing bar do not know how to do?: The arch support is an adjustable template or a small template

Q:I would like to ask the tunnel step method excavation, the height of each step is how to divide?: On the circular arc heading cutting method, the excavation of each cyclicfootage and steel frame with same interval, after the excavation will be used in the initial support, the excavation behind the steps of 8~10m, after the excavation construction of initial support and invert, and then the middle rock pillar grouting reinforcement. (4) of excavation the surrounding rock and the surrounding rock in deep buried section IV and supporting: IV rock by step excavation method, step up the steps behind 8~10m, up and down the steps of primary support construction must follow with the excavation. Rock class take the whole section excavation method. (5) are the simple types of rock excavation self assembling drilling trolley, with dump truck shipment mucking loader. In order to ensure the safety and stability of tunnel construction in soft rock section, the construction must follow the "weak blasting, little disturbance, short excavation, strong support and frequent measurement, tight lining", in the application of The following measures shall be taken

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:When the tunnel fight, there is no provision to fight how many meters left, only by one of the construction: Electric heating plate can be used for bonding or cold bonding (rubber water seal) or welding (plastic water stop) method, such as user connections are difficult, I can send technical personnel on-site guidance.

Q:What is the first project of tunnel constructionNow to do some of the tunnel program, you need to be the first to list out, a total of what? I know that the first branch, two lining, inverted arch, tunnel, pavement these: The YK24 + 300 ~ YK24 + is located in the silty clay, the whole weathered rock, the strong weathered rock distribution area, the soil is soft, the rock is broken, the pore is big, the stability is bad easy to collapse. Groundwater is mainly pore water and rock fissure water, rain water is large, easy deformation collapse

Q:There are no recycling tunnel templates: Tunnel template, as far as I understand, is the tunnel two lining template

Q:Highway bridge template needs, probably with the thickness of both the construction requirements can be met, and more cost-effective?: It is best to use the high turnover times, can also be used as the use of the beam die, more cost-effective

Q:I would like to ask the high-speed rail tunnel invert small side wall and arch with the small side of the wall of the hanging formwork of what a good method?: The pouring of inverted arch and the pouring of the short side wall, do not step in place, install the side die on the invert

Q:Two tunnel lining reinforced concrete template to price behavior can be contracted: There is two times of lining concrete pouring, the normal price is within 100 yuan, this is the pure artificial price, does not contain steel trolley and various materials two tunnel lining.

Q:Tunnel steel arch behind the steel mesh after a layer of fine iron wire mesh what effect is there?: 2, ingate construction shaft sealing, to get rid of advanced small pipe grouting reinforced concrete, and supported the upper ingate upper grille steel frame, injection, get rid of the upper concrete lower reinforced concrete, erecting of ingate to spray the concrete lower grille steel frame.
