The main factors influencing the service life of the tunnel and the construction period of the tunnel are determined by two procedures of excavation and lining. The two processes are simultaneously carried out in a narrow space of the tunnel, the construction quality is required, and the two processes cannot interfere with each other, so that extremely high requirements are provided for the construction method and the construction management.
The current construction method comprises the following steps: firstly, excavating operation is carried out in front of a tunnel; then, lining work is carried out at the rear.

The template adopted in the inverted arch formwork construction method has the following defects in any structure: 1, because the template covers the concrete, the vibration of the concrete needs to be carried out from a working window formed on the template, the vibration is limited by the structure of the template, the arrangement number of the working windows is limited, and the concrete surface needing vibration cannot be fully considered, so that the structural strength of the inverted arch concrete does not reach the standard due to insufficient vibration; 2, the process of opening and closing the working window is complicated, and the material distribution mechanism cannot be flexibly adjusted due to the position limitation of the working window during material distribution, so that the inverted arch pouring time is too long, the passage of a trestle is affected, and the tunnel excavation operation is seriously hindered; 3, the amount of steel used for the inverted arch template is large, so that large waste is caused to resources.
In order to solve the problems, the prior art explores and tests various methods, but all the methods have various defects so far and are difficult to popularize. For example: a needle beam arc-shaped transverse slip form trolley disclosed in CN102116158A, published as 2011.7.6, which adopts: the needle beam also comprises a longitudinal beam and a longitudinal beam jacking oil cylinder; the bottom of the needle beam is provided with a needle beam jacking oil cylinder and a needle beam supporting leg; the needle beams are arranged on the longitudinal beams, at least two arc frames are arranged at the lower parts of the longitudinal beams, at least three needle beam frames are arranged at the upper parts of the longitudinal beams, and the needle beam frames are connected by connecting beams; the arc frame is connected with the arc template by the initiative board, and the arc frame is connected with the arc template.

The structure and the use mode are as follows: 1. because the single arc-shaped track and the arc-shaped template are used for casting concrete for molding, only the concrete casting at the bottom of an inverted arch lining with a simple inverted arch molding curve, such as a circular tunnel, can be solved, and the tunnel construction with side walls and an inverted arch structure cannot be solved; 2. the driving plate is provided with the motor and the hydraulic injection motor, the driving plate slides on the arc-shaped track in the pouring process, and an electric wire connected with the motor or an oil pipe connected with the hydraulic injection motor moves along with the driving plate to be close to a concrete pouring surface, so that the arrangement of a circuit or a pipeline is difficult, the circuit or the pipeline is interfered with concrete distribution construction in the pouring process, and is easily polluted by splashed concrete, and the failure rate is high; 3. the requirement that concrete filling construction needs to be carried out on inverted arch concrete after inverted arch construction of the highway and the railway tunnel cannot be realized; 4. the tunnel traffic can be blocked after the tunnel is installed, and the requirements of keeping the tunnel to pass and simultaneously expanding all construction procedures of the tunnel cannot be met; 5. simple function, complex structure, heavy weight and high cost.
