Before the pouring of the secondary lining concrete of the tunnel, the trolley is locally reinforced and infirm in the positioning process of the trolley of the secondary lining trolley; and the concrete is unevenly distributed in the hopper in the pouring process, so that the left and right stresses of the tunnel secondary lining trolley are uneven, bias voltage is generated, and adverse effects are generated on the stability of the trolley structure.
Deformation of the two-lining trolley in the tunnel is mainly shown in distortion, the two-lining trolley lifts and falls by depending on the oil cylinder arranged on the trolley to be controlled, the oil cylinder is fixed on the longitudinal beam, the distortion of the trolley causes the longitudinal beam to be distorted, and then the axial force of the oil cylinder cannot be vertically acted on the longitudinal beam, and the trolley has collapse risks. Meanwhile, the ends of the trolley are not positioned on the same cross section due to the distortion deformation of the trolley in the tunnel, when the next slab is constructed in a second lining, the trolley cannot be uniformly overlapped with the ends of the second lining in the tunnel, the overlapping part of the short side wall is staggered, even the inverted arch and the construction seam of the second lining cannot be integrated into a double seam, and the secondary lining of the tunnel is cracked when the tunnel is unevenly settled, so that the overall stability of a concrete structure is influenced.

The device can monitor the state of the two-lining trolley in the tunnel after being positioned, so that the left and right stress of the two-lining trolley in the tunnel is uniform, and the generation of bias voltage and collapse risks are avoided. The two lining trolleys in the tunnel are arranged on the same cross section, when the next plate is constructed with two lining, the trolleys can be evenly overlapped with the ends of the two lining in the tunnel, the overlapping parts of the short side walls are not staggered, the double-joint integration of the construction joints of the inverted arch and the two lining is ensured, and the structural stability of the trolleys is ensured.
The purpose of the invention is realized by the following technical scheme: the deformation monitoring device for the tunnel secondary lining trolley comprises a base, a cylinder, a string, a spring, a dial, a hoop, a screw and a nut.

And the right end of the second string extends out of the cylinder and is externally arranged on a template at the junction of the tunnel secondary lining trolley arch wall template and the end template.
When the monitoring position of the tunnel secondary lining trolley is displaced, the spring generates telescopic deformation, the thin rope drives the dial scale, the dial scale rotates, and the deformation of the trolley can be determined according to the numbers on the dial scale.
Compared with the prior monitoring technology, the monitoring position of the tunnel secondary lining trolley has the advantages that:
1. the cost is low: compared with the deformation monitoring device of the optical measuring instrument tunnel secondary lining trolley, the cost is low, the investment cost of the engineering construction measuring instrument can be reduced, and meanwhile, the investment of measuring personnel is reduced;
2. accuracy of measured data: the deformation monitoring device for the tunnel secondary lining trolley can be mounted on the trolley at any angle, and the deformation generated by the trolley in the concrete pouring process can be measured more accurately.
3. The environmental applicability is strong: the deformation monitoring device for the tunnel secondary lining trolley is applicable to measuring the deformation of the relatively hidden part of the trolley. The optical measuring instrument is interfered by a complex structure of the tunnel secondary lining trolley, the limitation of a measuring part is large, and the monitoring device has stronger applicability relative to the complex structure of the tunnel secondary lining trolley and is not influenced by a tunnel driving vehicle.
4. The operation is convenient: the deformation monitoring device for the tunnel secondary lining trolley has the advantages that the steering of the dial can directly reflect the deformation direction of the trolley, the deformation value can be directly read, and the reading result is not influenced by environmental factors such as temperature, vibration and the like.
