Product Description:


Products Introduction & Application:

● Keep suitable formwork strength, make the vault and side wall be smooth in the secondary lining operation.

● Limitedly analysis and calculate the stress to optimize the structure, which can guarantee the strength and stiffness, and    also reduce the steel consumption and construction cost.

● Implement standardization renovation, use standard component, promote its versatility and improve repeated utilization    factor.


Features:
①Good concrete quality
 With full steel materials, high load bearing capacity and stiffness is achieved, that makes perfect concrete surface.
②High-speed of installation and removal of the form
 The formwork is fully hydraulic, with hydraulic cylinder to prop & strip, and lock mechanically.
③Easy operation and safety

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:How to fill in the tunnel template
The template is firm and smooth, there is no error, such as leakage
Q:On the measurement of total station
Slag road slope line, shotcrete receiver measurement, measurement of highway tunnel excavation section, the most important measure is the monitoring and measurement precision of total station but couldn't finish that much. Ha-ha
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:There are no recycling tunnel templates
Tunnel template, as far as I understand, is the tunnel two lining template
Q:What is the simple calculation method of the tunnel excavation unit price
Fully integrated unit price = labor + material equipment + + + + + + + management fees
Q:How to remove the template of the two lining trolley moving outside the tunnel
No, the car is a mechanical structure, the first car on the template brush oil release agent or diesel oil, to prevent sticking
Q:Tunnel construction procedure A cycle of steps
The construction and tunnel portalWith the support from top to bottom layered excavation hole slopes, and Myeong Dong, and permanent and temporary outside waterproof and drainage should be first, make the surface smooth water, avoid surface water erosion on slope. Is necessary to take artificial slope repair, prevent overbreak, reduce disturbance to the adjacent area; excavation slope will be used in the design of the door, reducing exposure to rock weathering, support to follow, within the jurisdiction for high slopes, if not timely, can not guarantee the safety, and many of the human condition waste,The lining must check and recheck side wall foundation Myeongdong geologic condition and the bearing capacity of the foundation, to meet the design requirements, measurement lofting, frame formwork support, assembling reinforcement, inside and outside the template, the first wall arch integral casting lining concrete, mixing pump into the mold, insert type vibrator with attached type vibrator tamping compaction device.For the construction of portal portal with cut bamboo, also for cutting bamboo cut, plane mounted wooden formwork according to the slope, the slope angle and side end die die fixed into a whole.The waterproof layer and backfillingAfter the completion of open cut tunnel lining strength up to 50% can be removed outside the mold, with a waterproof layer, each layer of backfill should be symmetrical on both sides of the height difference is not greater than 30cm, not more than 50cm, after re stratified backfill to the vault, filled to the completion of a good surface aquifuge.
Q:How to design the general layout of the tunnel construction organization design
The location and sketch map of explosive storehouse, spoil yard, office location, living area, entertainment area, temporary drainage ditch.
Q:What is the width of a ring in a tunnel
Generally used in the tunnel as a two car lining template
