Brief Introduction

The automatic hydraulic tunnel formwork is the equipment to make
the concrete lining for the tunnel in one time.The empty gantry allows the
transport vehicles to pass. The motor gearbox is adopted to drive
the whole equipment, the formwork is fully hydraulic, with hydraulic
cylinder to prop & strip, and lock mechanically

Advantage

◆ Good concreting quality

◆ High-speed of installation and removal of the form

◆ Easy operation and safety

Tunnel Steel Template with High-speed of Installation and Removal

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 hole in the template above people standing on the head of I welded pipe, connected with concrete pump.

Q:The tunnel structure of plastic mould: In the use of the whole tunnel mode is not as flexible as semi tunnel mode, the lifting equipment requirements are higher, it is gradually being semi tunnelMode substitution.

Q:The tunnel lining is wood, how should support?: Small pipe or large, medium pipe shed is the advanced support for the broken rock area or into, out of the hole, of course, grouting, grouting without losing the significance of the implementation.

Q:How to calculate the lining formwork trolley in the tunnel construction, is the fixed assets or the turnover materials?: In the construction of the tunnel lining template can belong to the low value consumables in accounting, purchasing back into low value, and share in the future cost of 50%, scrap reamortization into 50% of the cost of this method is of low value consumables 55 amortization method; fixed assets, equipment car belonging to the class the asset depreciation period of 10 years. The lining template trolley for a device, rather than separate accounting, and the template should be turnover materials? Added: I engaged in casting model in the low value consumable, car is of course equipment assets added: template is a collar with the repeated use of the low value consumables, which belongs to the class of tools, you can also be classified as turnover materials, but according to the use of reasonable cost sharing principle after ask: you the manufacture of accounting, and it is in the tunnel construction, the construction enterprise to buy trolley. I personally feel that the template should be separated from the car accounting, so more true and accurate. Thank you

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:Would you please tell me the difference between the concrete and shotcrete in the tunnel?: Jet coagulation: the construction method of spraying fine concrete with spray gun. It is often used to fill the lining of tunnel lining, wall, ceiling and other structures.

Q:What is the width of a ring in a tunnel: Of course, the assembly of the tunnel, such as subway shield tunnel, a ring is the length of the shield segment, there are 1.0m, 1.2m, 1.5m, 2.0m.

Q:Ask, general highway tunnel measurement with the total station to measure which aspects? The more detailed the better: The first instrument identification, according to the drawings issued by the tunnel portal design to determine, determine the portal after the slope portal to lofting, tunnel excavation and excavation contour checking (i.e. overexcavation measurement)

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:What are the steps? If you build a template, how to fill in the concrete. The tunnel is to dig all the generalist pouring, or digging into the side. Simply say. Better picture. In addition, we have seen a video, the shield machine to dig up the tunnel after the installation of a number of prefabricated panels, but these prefabricated plate is curved. Do not have to fill in a semicircle tunnel?: Tunnel concrete is completed by the way of edge excavation and lining. After the excavation, the shotcrete is used as the initial support, and then the reinforcing steel mesh is set up. Only after the two lining.
