Embodiment 1

[0031] Such as figure 1 , the observation car 13 is set on the vault template, the observation probe 12 is installed on the observation car 13, the guide rod 14 is installed at the left end of the observation car 13, and the guide rod 14 is connected to the placement room 15 provided at the end mold place, and the guide rod 14 can be controlled by the winch mechanism. Rod 15 advances or retreats, and can control dolly to retreat in the placement room 15 from the perfusion hole 3 at the farthest end, and placement room 15 is provided with valve, closes valve after dolly returns to placement room 15. The wheelbase of both sides rollers on the observation car 13 is greater than the diameter of the pouring hole 3 .

[0032] Drill holes in the top form of the lining trolley, and drill an observation hole at the highest longitudinal point of the vault formwork. The observation hole is located at the end closest to the lining of the upper ring, and drill 2-5 groups of grouting holes ...

Embodiment 2

[0037] As shown in the figure, an observation car 13 is set on the vault formwork, an observation probe 12 is installed on the observation car 13, a guide rod 14 is installed on the left end of the observation car 13, and the guide rod 14 is connected to the placement room 15 provided at the end mold, and can be moved by the winch mechanism. Control the guide rod 15 to advance or retreat, and the dolly can be controlled to retreat from the farthest filling hole 3 to the placement room 15. The placement room 15 is provided with a valve, and the valve is closed after the dolly returns to the placement room 15.

[0038] Drill holes in the top form of the lining trolley, and drill an observation hole at the highest longitudinal point of the vault formwork. The observation hole is located at the end closest to the lining of the upper ring, and drill 2-5 groups of grouting holes according to the number of pouring holes 3. There are two grouting holes for each group, which are symmetr...

Abstract

The invention discloses a tunnel cavity-free lining trolley capable of performing mobile shooting. The tunnel cavity-free lining trolley includes a lining trolley body and an end mold. The tunnel cavity-free lining trolley is characterized in that an observation hole and an observation tube (2) are arranged at one end, near an upper ring lining, of a top arch template, an observation vehicle (13)and an observation probe (12) are installed on the top arch template, one end of the observation vehicle (13) is connected with a guide rod (14), and the other end of the guide rod (14) is installed at a placement room (15) of the end mold. The tunnel cavity-free lining trolley uses the observation tube to monitor the condition of perfusion at the distal end during the perfusion of concrete, the observation vehicle is used for observing the condition of perfusion at the proximal end of the concrete at a close distance with no dead angle of observation, and cavities in the perfusion process canbe promptly found.

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...
