Embodiment 1

[0031] An observation hole and a grouting hole are provided on the vault formwork of the lining trolley, and a fixed flange 4 is welded below the observation hole and the grouting hole. Bolts are welded on the fixed flange 4, and the positioning flange 5 is connected by bolts. There is a chute on the upper surface of the fixed flange 4, and an inserting plate 10 is set between the chute and the vault formwork. There is a positioning cylinder 6 in the center of the positioning flange 5, and a pin hole is opened on the cylinder wall, and the observation tube 2 is inserted into the positioning cylinder. 16 and stretch into the place near the tunnel waterproof board 11 through the observation hole. Install the grouting pipe 1 in the grouting hole again.

[0032] A section of observation window 18 is arranged at the top of observation tube 2, and observation window 18 is an annular transparent structure, and camera and lighting lamp, stepper motor and column 17 are installed in obs...

Embodiment 2

[0035] First, punch holes in the top form of the lining trolley, except for the second lining filling hole 3 of the vault, drill 3 vault grouting holes and 2 observation holes along the highest longitudinal position of the vault formwork, and 3 vault filling holes The holes are grouting holes, intermediate vent holes (spare grouting holes), and end die vent holes in sequence. Weld fixed flange 4 under the hole, fixed flange 4 upper surface offers chute, and flashboard 10 is installed in the chute, and flashboard 10 center has hole, can slide flashboard 10 to open or close observation hole. The fixed flange 4 is connected to the positioning flange 5 by bolts. One positioning flange 5 is used to install the grouting pipe 1, and the other positioning flange 5 is used to install the observation tube 2. The center of the positioning flange 5 has an observation tube 3 or The installation hole of grouting pipe 1 is used to install bottom cover 6 at the bottom of the installation hole...

Embodiment 3

[0039] Embodiment 3: This embodiment is to transform the existing trolley, and the transformation and construction steps are as follows:

[0040] (1) Mounting flange for the hole in the roof plate of the trolley

[0041]First, punch holes in the top mold of the lining trolley. Except for the second lining perfusion hole 3 of the vault, three vault perfusion holes and two observation holes are drilled along the highest longitudinal position of the vault formwork, and the three vault perfusion holes are sequentially drilled. It is the grouting hole, the middle vent hole (spare grouting hole), and the end die vent hole. Weld the fixed flange 4 under the five holes. The fixed flange 4 is connected to the positioning flange 5 by bolts. One positioning flange 5 is used to install the grouting pipe 1, and the other positioning flange 5 is used to install the observation tube 2. The center of the positioning flange 5 has an observation tube 3 or The mounting hole of the grouting pip...

Abstract

The invention discloses a tunnel hole-free lining trolley. The tunnel hole-free lining trolley comprises a lining trolley, wherein a top arch template of the trolley is provided with a concrete pouring hole (3) and a pre-buried grouting pipe (1), and observation pipes (2) are distributed on the top arch template. By adopting the tunnel hole-free lining trolley, the grouting situation of concrete in the molding plate is observed by utilizing an observation probe to stretch into an observation molding plate, so that the hole can be effectively prevented, and a plurality of observation pipes areinstalled on the template to realize all-around monitoring.

Description

technical field [0001] The invention relates to a tunnel lining trolley, in particular to a trolley vault lining structure. Background technique [0002] When the lining trolley is used for the secondary lining of the tunnel, there are cavities in the concrete, which will have a great impact on its strength. Generally, the lining trolley is easy to produce cavities in the top arch part, and it is not easy to find the cavity during the pouring process. The voids were only discovered when the lining trolley was demoulded; even after demoulding, the voids were not visible, but there were already voids inside the concrete. The main reasons are: (1) When the lining trolley pours the upper part of the roof arch, since there is no pouring window, only the pouring port, the pouring personnel cannot observe the pouring situation of the upper part of the roof arch as in the pouring window, that is, they cannot clearly Observe the perfusion in the upper part of the arch. (2) In the p...
