Tunnel lining formwork instructions

Tunnel lining formwork is a non-standard product specially designed and manufactured for concrete linings of various tunnels, culverts and other sections. It has the functions of vertical mold and demoulding function, high surface finish of lining and fast lining speed.

The working process of Tunnel lining formwork is as follows:

First,Check whether the tunnel construction conditions meet the design requirements of the template trolley

since the template trolley belongs to non-standard equipment, the use conditions must meet the design requirements before lining.

  1. Check whether the road surface elevation and road surface condition meet the design requirements, the road surface elevation +; road surface condition: concrete road surface.
  2. Check whether the grounding screw support position meets the design requirements, and the ground screw support position: as shown in the figure.
  3. Check whether the sleepers and rails meet the design requirements;
  4. Check whether the height of the short side wall meets the design requirements;
  5. Check whether the outer surface of the steel formwork is coated with a release agent.

Lining trolley electrical parts

1. It is necessary to introduce a three-phase four-wire power supply, otherwise the leakage circuit breaker will not function as a leakage protection trip.
2. The green indicator on the panel of the power distribution box is the power indicator.
3. Oil pump motor thermal relay setting current: 11.6A.

Analysis of common faults in electrical parts

Fault phenomenon Reason Approach
The motor does not start properly 1.The circuit fuse is broken

2.The thermal relay normally closed contact JR is not reset

3.Normally closed contact bad contact

4.Poor contact or break between the start and stop buttons

 1. Replace the fuse

2. Reset the contact to close it

3. Repair contacts

4. Connect the line, repair button point
One of the positive and negative buttons can control the motor and the other cannot control the motor. 1. There is a button contact in the anti-control button.

2. There is an interlocking normally closed contact in the positive and negative control buttons.

 1. Repair contacts

2. Repair the contacts, make it closed
No positive or negative buttons can be activated 1. The reverse contactor coil is damaged.

2. The thermal relay normally closed contact is not reset.

3. Check if the power supply and plug are loose.

4. Check if the stop button is damaged or if its line is connected.

 1. Replace the contactor coil

2. Reset pad relay normally closed contact

3. Inspection, replacement

4. Inspection, replacement

Hydraulic system installation, use, maintenance instructions

  • 1. Inventory all parts and match the packing list.

  • 2. Check if the fuel tank is clean, cover the fuel tank cap, and add 115 liters of clean YA-N46 hydraulic oil from the tank air filter.

  • 3, according to the requirements of the cylinder layout
    (1) Before welding the pipe, the burr of the pipe head should be removed, (with a round file), and the high-pressure wind blows the debris inside the pipe.
    (2) The welded pipe should be aligned, welded, and not allowed to leak oil.
    (3) Pipe the pipe according to the requirements of the pipe, install all the gaskets, rings, and clean the debris in the pipe.
    (4) Connect the multi-way reversing valve and cylinder to the pipeline (the mechanical lock cylinder must be connected to the left and right valves of the multi-way reversing valve).
    Note: There are no 1, 2 hoses.

  • 4. Jog the motor to check the motor steering and start the oil pump to test the various cylinders (the pressure has been adjusted at the factory). If the system pressure is not established (the cylinder does not move), first check whether the joints of the pipes are leaking oil, and if necessary, exclude them. Then adjust the relief valve to see the pressure from the pressure gauge is 12MP. After adjusting, close the pressure gauge switch and pay attention to the oil level.

  • 5, often clean the filter element, remove the filter debris, should be replaced when blocked.

  • 6. After the first refueling, replace the new oil in three cycles, and then change the hydraulic oil condition irregularly. It is recommended to replace the new oil in 30 cycles.

Lining trolley maintenance

Note:

1. Full hydraulic tunnel lining formwork design reference book:
(1) “Code for Design of Steel Structures”
(2) “Technical Rules for Construction of Railway Bridge Tunnels and Lining Works”;
2. Most parts of the trolley are non-standard parts.
3. The walking distance of the whole machine is short and the speed is slow. In the tunnel construction, if the deformation of the steel structural parts does not occur, no overhaul is required.

Level 1 maintenance once a day

Project Technical requirements and instructions
Walking system Drive chain and grease
Various bolts There should be no looseness or slippery phenomenon
Various jacks, cylinders Should be in the working size position when working
Grouting port, working window No leakage
Plug board When working, there should be no leakage and work well.
Walking mechanism (when walking) Smooth transmission, no abnormalities
Check the joystick (no load) It should be easy to operate, accurate in position and reliable in positioning
Steel formwork outer surface It should be kept clean after demolding, remove the concrete that may adhere to it, and apply the release agent evenly and comprehensively.
Electrical control system According to the electrical instructions
Hydraulic system
