[0117] Preferably, the annular cleaning and rock coring can be performed synchronously (or asynchronously). In their respective operation modes, the annular cleaning device 3 and the coring mechanism 4 have their respective crawling trolleys (carrying structures) installed at a certain distance and driven in the same direction at the same time, thereby avoiding interference caused by repeated travel areas when operating in the two modes.

[0118] As a further embodiment of the present invention, the specific process of using the above-mentioned TBM auxiliary equipment to perform circumferential cleaning operations is as follows:

[0119] After the annular sweeper 3 moves to the designated working area in the excavation (axis) direction relying on the annular beam 2, the support cylinder 302 drives the cleaning roller 305 (installed on the telescopic support 303) to stick to the hole, and the shield mounting seat 30305 compresses the spring 30303, so that the spring 30303 has a certain initial stroke compression amount, and then the driving motor 30102 drives the first crawling trolley 301 to perform circumferential movement on the annular beam 2 to perform circumferential cleaning of the hole wall;

[0120] The initial compression of the spring 30303 can make the cleaning roller 305 compress / elevate during the circumferential cleaning process to adapt to the cleaning of irregularly changing hole walls (diameters), improve the cleaning effect, and also avoid large rigid interference during the operation process that may cause damage to the equipment. The aerosol device 304 is arranged on both sides of the roller 305, which can throttle the water vapor passing through the pipeline to achieve spray cleaning of the hole wall (or switch to the atomized water vapor mode to reduce dust on the roller 305 when it is in the cleaning area).

[0121] As a further embodiment of the present invention, the specific process of using the above-mentioned TBM auxiliary equipment to perform rock coring operation is as follows:

[0122] The coring mechanism 4 moves to the designated operation area in the excavation (axis) direction by relying on the annular beam 2. Afterwards, the second crawling trolley 401 carries the swing motor 402 and the coring drill 403 thereon and performs circumferential movement on the annular beam 2 to reach the designated circumferential coring position. The radial rock entry angle of the coring drill 403 can be adjusted by the swing motor 402 to perform coring operation.

[0123] The coring drill 403 realizes the extension and retraction of the propulsion beam 40302 through the drilling rig propulsion cylinder 40305, thereby achieving the coring operation requirements within a certain range (hole wall diameter); the drill clamp 40306 can support the drill and stably clamp the drill during the drilling process, thereby achieving stable positioning during the drilling rig operation to replace the drill rod and realize coring operations in deeper rock formations.

[0124] As a further embodiment of the present invention, based on the fact that the TBM equipment needs to have two different functions, namely, coring the rock layer and cleaning the excavated hole wall in an annular direction, the specific requirements of each function need to be clarified:

[0125] Rock coring: realize the rock coring function at different rock entry angles and depths within the 240° range on the upper side (circumferential) of the excavation section; Circumferential cleaning: covers the cleaning and dust reduction functions of the tunnel wall within the 300° range on the upper side (circumferential) of the excavation section. Because both require the circumferential range of the section to operate, the two can be integrated (the main structure is shared) and equipped with a split structure design. This can improve the utilization rate of the equipment space and the integration of the equipment. The structural design and implementation methods are as follows:

[0126] In order to realize the circumferential operation range on the cross section, the circumferential beam 2 is used as the circumferential support and the functional equipment carrying device (circumferential) moving track, and the circumferential (driving) is realized by the gear on the carrying device meshing with the gear ring on the annular beam; at the same time, the moving wheel group 203 on the annular beam 2 cooperates with the walking track 1, so that the annular beam 2 also needs to have a certain range of travel movement in the axial direction of the excavation tunnel, which can improve the operation flexibility of the overall equipment;

[0127] The annular cleaning mechanism is mainly equipped with an aerosol device 304 and a cleaning roller 305 to realize the circumferential drive along the annular beam 2, and to adjust the aerosol effect and the cleaning roller adaptation range during the operation process to meet different environmental operation requirements;

[0128] The rock formation coring mechanism is mainly equipped with a coring drill 403 to realize circumferential drive along the annular beam 2, and to realize coring operations at different radial rock penetration angles and different depths through a swing motor 402 at different circumferential angular positions.

[0129] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
