Using above-mentioned technical proposal, after the completion of tunnel excavation, support meanss are installed, between curved baffle and tunnel Accommodating chamber is formed, then by placing concrete in accommodating chamber, waits concrete setting to dry, then control hydraulic stem to receive downwards Contracting, then supporting table is moved down, and second support inwardly pulls curved baffle so that support meanss can be de- with concrete layer From convenient to dismantle and mobile;Boss is stuck between the first curved baffle and the second curved baffle, forms a semi-circular shape, is risen While supporting role, the effect of the shaping of limitation concrete is also acted as.
Further limit, the first curved baffle lower end is provided with guide rail wheel, and the second curved baffle lower end is provided with leads Rail wheel, the hydraulic stem lower end is provided with guide rail wheel.
Fittable slackening device and dismounting Mobile support device when, can it is more laborsaving, operation more facilitate, shorten construction Cycle.
Further limit, the hydraulic stem and connecting rod junction are provided with screens projection, and the screens projection is looped around liquid Depression bar upper end, the screens projection upper surface is concordant with the inner wall end surface of stopper slot lower end.
Screens raised role is to form a torque more long with second support, is effectively increased second support The ability of pressure is born, while also add the service life of first rotating shaft.
Further limit, the journal stirrup end is circular shape.
It is convenient for assembly, it is also more beautiful.
Further limit, the guide rail wheel of the hydraulic stem lower end there are 2 rows.
Reliability gets a promotion.
Further limit, the thickness of the curved baffle is 3cm.
While proof strength, the weight of curved baffle is also effectively controlled.
The utility model compared to existing technology, controls simple and convenient, reliability high.
