Problems solved by technology

Especially in the construction of small-space long-distance overlapping tunnels, after the excavation of the lower tunnel is completed, in order to ensure the safety of the formed tunnel structure during the tunnel excavation process, construction personnel are required to monitor and operate the supporting trolley on the lower tunnel. low, and because the light in the tunnel is dark, the construction personnel cannot fully grasp the situation in the tunnel, which not only poses a great safety hazard, but is also prone to mistakes

Embodiment 1

[0040] like Figure 1 to Figure 3 As shown, the present invention provides a visual automatic supporting walking trolley used in the construction of shield overlapping tunnels, comprising a supporting gantry 100, at least one supporting mechanism 200 arranged on the supporting gantry 100 and used for supporting the tunnel, The bottom beam 300 at the bottom of the supporting gantry 100, the rollers 400 provided on the bottom beam 300, and at least one monitoring mechanism 500 provided on the supporting gantry 100 and used for monitoring the running condition of the trolley. By installing the visual trolley in the overlapping lower tunnel, the construction of the shield machine in the upper tunnel is synchronized, and the support of the lower tunnel by the support mechanism 200 fully guarantees the stress safety of the lower tunnel structure, and the monitoring mechanism 500 monitors the inside of the tunnel. The actual situation of the tunnel is convenient for the technicians t...

Embodiment 2

[0054] A method for constructing overlapping shield tunnels, which adopts the aforementioned visual automatic support traveling trolley used in the construction of overlapping shield tunnels to support the overlapping shield tunnels, and specifically includes the following steps:

[0055] The S1PLC controller receives the instruction issued by the monitoring room of the shield machine to start the visual automatic supporting trolley;

[0056] The S2PLC controller starts the hoist 700, so that the hoist 700 drives the visual automatic support traveling trolley to move forward along the track 600; the hoist 700 provides forward power for the visual automatic support traveling trolley;

[0057] The S3 PLC controller starts the monitoring mechanism 500 to monitor at least one of the conditions in the tunnel, the operation of the hydraulic cylinder and the deformation of the supporting gantry 100; the PLC controller controls the connection between the first drive motor and the secon...

Abstract

The present invention relates to the technical field of tunnel construction, in particular to a visual automatic support walking trolley used in the construction of shield overlapping tunnels, including a support portal frame, which is arranged on the support portal frame and is used to support the tunnel. The bottom beam supporting the bottom of the mast, the rollers arranged on the bottom beam, and at least one monitoring mechanism arranged on the supporting mast and used for monitoring the running condition of the trolley. The invention realizes the synchronization with the construction of the upper tunnel shield machine by installing the visual automatic support walking trolley in the overlapping lower tunnel, fully guarantees the safety of the lower tunnel structure, and greatly reduces the manpower input of the construction personnel and reduces the The project cost is reduced, and the occurrence of personnel safety accidents is avoided. It is not necessary for construction personnel to enter the tunnel to fully understand the situation in the lower forming tunnel, and it can effectively keep the support of the lower tunnel and the excavation of the upper tunnel at the same time.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a visual automatic support traveling trolley and a construction method used in the construction of shield overlapping tunnels. Background technique [0002] The shield tunneling method has been widely used in urban rail construction. Due to the complexity of subway line planning, it often faces the problem of overlapping tunnel construction. Especially in the construction of small clear distance and long-distance overlapping tunnels, after the completion of the lower tunnel, in the process of the downward tunnel, in order to ensure the safety of the formed tunnel structure, it is necessary for the construction personnel to monitor and operate the lower tunnel support trolley on site, which is not only efficient In addition, due to the dark light in the tunnel, the construction personnel cannot fully grasp the situation in the tunnel, which not only poses a great safet...
