A lining method suitable for a corbel lining section of a loading and unloading zone of an underground cave depot is based on the lining trolley, and further comprises the following steps:
the first step is as follows: the embedded bolt positioning device 14 is installed on the side wall bracket template 12, the embedded bolts are positioned at the design positions through the upper and lower fastening bolts 14e and the front and rear fastening bolts 14f, then the side wall bracket trolley is driven to move to the construction position through the side wall travelling assembly 2, the side wall lifting assembly 3 upwards lifts the side wall template supporting assembly 1 and the side wall bracket template 12 to the design positions, and finally concrete is poured.
Because each side wall bracket trolley is used for constructing the single side of the underground cave depot, the side walls on the left side and the right side are constructed simultaneously for saving time during specific construction. When pouring, the concrete is vibrated by the vibrating rod or the flat vibrator, so that transition bubbles are prevented from being generated in pouring, the compactness of the concrete is influenced, and after pouring is finished, strip-mold maintenance is required.
The second step is that: after the concrete poured in the first step reaches the demolding condition, the upper fastening bolt 14e, the lower fastening bolt 14e, the front fastening bolt 14f and the rear fastening bolt 14f are unscrewed, then the embedded bolt positioning device is lifted upwards, after the embedded bolts are leaked out, the side wall lifting assembly 3 drives the side wall formwork supporting assembly 1 to descend, then the side wall walking assembly 2 drives the side wall bracket trolley to transversely move away from the side wall, the side wall bracket formwork 12 is made to leave the concrete surface, finally the side wall walking assembly 2 drives the side wall bracket trolley to move to the next construction position, and the operation is repeated until the construction of side wall and bracket lining concrete is completed.
Because side wall walking subassembly 2 adopts the walking wheel that can change the walking direction, consequently when changing the moving direction of side wall bracket platform truck, need make universal traveling wheel leave ground through 3 work of side wall lifting unit earlier, then change the direction, change the completion back, make universal traveling wheel fall to the ground. In order to facilitate the movement of the side wall bracket trolley, the side wall bracket trolley can move with the assistance of a loader and other walking machines.
The third step: install arch portion template 13 on the arch portion platform truck, after the side wall bracket concrete intensity reached the requirement, remove whole platform truck to lining cutting position department through arch portion walking subassembly 5, make arch portion template 13 move to the design position through arch portion lifting unit 6 and arch portion sideslip subassembly 7, then pour the concrete, when pouring, carry out the vibration processing through vibrating rod or flat vibrator to the concrete, prevent to produce the transition bubble in pouring, thereby influence the quality of concrete, after accomplishing to pour, need carry out the area mould maintenance. When the arch is poured, construction can be carried out only after the strength of the concrete of the side wall corbels meets the requirement, and the construction can be carried out without waiting for the completion of the pouring of the concrete of all the side wall corbels.
The fourth step: and after the concrete poured in the third step reaches the demolding strength, the vertical side plates are rotated to leave the concrete surface through the side plate horizontal moving assembly, the whole arch part trolley is driven to descend through the arch part lifting assembly 6, the whole arch part template 13 is enabled to leave the concrete surface, then the arch part walking assembly 5 drives the arch part trolley to move to the next construction position for repeated construction, and the construction of arch part lining concrete is completed. In order to facilitate the movement of the arch trolley, the movement can be assisted by a walking machine such as a loader. The side plate horizontal moving assembly can be a telescopic oil cylinder or a screw nut structure. After the arch part is lined with concrete, the track of the bracket crane is installed on the embedded bolt 15.

A lining method for a corbel lining section in a loading and unloading zone of an underground cavern as claimed in claim 6, wherein: before pouring in the S1, installing embedded bolts (15) at positions, where the track of the bracket crane needs to be installed, on the bracket through embedded bolt positioning devices (14); in S2, the embedded bolt positioning device is taken out upwards, so that the embedded bolt (15) is exposed out of the concrete surface, and then the side wall template supporting assembly (1) descends under the action of the side wall lifting assembly (3); and in S4, after the arch part is lined with concrete, installing the track of the bracket crane on the embedded bolt (15).
8. A lining method for a corbel lining section in a loading and unloading zone of an underground cavern as claimed in claim 6, wherein: in S1 and S3, during pouring, the concrete is vibrated by a vibrating rod or a flat vibrator, and after the pouring is finished, the curing with a mold is carried out.
9. A lining method for a corbel lining section in a loading and unloading zone of an underground cavern as claimed in claim 6, wherein: in S1, two side wall corbel trolleys are constructed on two sides of the underground cave depot at the same time, when the width of the section of the underground cave depot is enough, the two side wall corbel trolleys are constructed side by side, and when the width of the section of the underground cave depot is limited, the two side wall corbel trolleys are constructed in a staggered mode; in S2, when the side wall walking assembly (2) below each side wall bracket trolley changes the moving direction, the moving direction of the side wall walking assembly (2) is changed after the whole side wall bracket trolley is jacked up through the side wall lifting assembly (3).
