The technical scheme of the invention is realized as follows: the shielding device of the L1 area spraying and mixing equipment for the TBM comprises a frame formed by two semicircular mounting brackets, two mounting bracket supporting rods connected between the same side ends of the two mounting brackets, and a plurality of rubber apron plates which are connected between the two mounting brackets of the frame in an annular uniform distribution manner and are subjected to surface treatment by a spacer; the middle part of the support rod of the mounting bracket is provided with a notch for free access of the L1 automatic spraying and mixing equipment; a plurality of telescopic cylinders are uniformly hinged on the mounting bracket at one end of the frame, and a plurality of support cylinders are uniformly hinged on the mounting bracket at the other end of the frame; the ends of the rubber apron are connected with the mounting bracket through a plurality of telescopic springs, and the side parts of every two adjacent rubber apron are combined in a lap joint mode, so that all the rubber apron are integrally matched together in a fish scale shape.
Preferably, the mounting bracket support rod is of a telescopic structure.
Preferably, the telescopic oil cylinder is hinged on the inner side surface of the mounting bracket.
Preferably, the support cylinder is hinged on the intrados of the mounting bracket and is perpendicular to the arc of the mounting bracket.
Preferably, the whole positions between the telescopic oil cylinder and the supporting oil cylinder are symmetrically distributed.
Compared with the prior art, the invention has the following beneficial effects: the invention provides an effective combination of a rubber apron, an apron mounting rack, a telescopic spring, a pushing telescopic oil cylinder, a supporting oil cylinder and the like which are subjected to surface treatment. Can be in spouting the concrete that drops of effectively sheltering from in the equipment work of mixing to play the effect of protection L1 district not polluted, reduced the degree of difficulty of manual cleaning shotcrete promptly, can guarantee the cleanness of L1 again, improved L1's operational environment and work efficiency. The method is simple to operate, high in practicability and good in application prospect.

Detailed Description
The invention will be further described with reference to the drawings and the specific examples.
As shown in fig. 1 to 3, the blocking device of the L1 zone spraying and mixing equipment for TBM of the present invention comprises a frame composed of two semicircular mounting brackets 2 and two mounting bracket support bars 6 connected between the same side ends of the two mounting brackets 2, and a plurality of rubber panels 1 which are connected between the two mounting brackets of the frame in a ring-shaped uniform distribution manner and are subjected to surface treatment by a spacer; a notch for free access of the L1 automatic spraying and mixing equipment is formed in the middle of the mounting bracket supporting rod 6; three telescopic oil cylinders 4 are uniformly hinged on the mounting bracket 2 at one end of the frame, and three support oil cylinders 5 are uniformly hinged on the mounting bracket at the other end of the frame; the ends of the rubber scalps 1 are connected with the mounting bracket 2 through the telescopic springs 3, and the side parts of every two adjacent rubber scalps are combined in a lap joint mode, so that all the rubber scalps are integrally matched together in a fish scale shape; the telescopic oil cylinder 4 is hinged to the inner side surface of the mounting bracket 2; the support oil cylinder 5 is hinged on the inner cambered surface of the mounting bracket 2 and is perpendicular to the arc line of the mounting bracket; the whole position between the telescopic oil cylinder 4 and the supporting oil cylinder 5 is symmetrical.
In the embodiment, firstly, the device prepares a high-performance rubber apron, so that the rubber apron has higher strength and toughness so as to resist larger external force impact; secondly, the device designs a pair of parallel mounting brackets for mounting the rubber apron, and a certain number of telescopic springs are connected between the mounting brackets and the apron; furthermore, for the convenience of construction of being convenient for, the flexible hydro-cylinder of promotion of a certain quantity and support hydro-cylinder link to each other with rubber apron installing support have been installed under this device, and the shielding device that assembles can receive and release in the shield below when not using.
