As a further aspect of the present invention: the upper bottom of the sleeve joint seat is evenly provided with bevel teeth.
As a further aspect of the present invention: and a settlement monitoring device is arranged at the right side position on the steel beam fixing seat on the right side.
As a further aspect of the present invention: the settlement monitoring device comprises a graduated scale arranged on the right bearing seat, a fixed block is connected to the position, close to the bottom, of the steel beam fixing seat on the right side, a connecting rod is installed on the fixed block, a pointer is installed on the connecting rod, and the pointer is opposite to the graduated scale.
Compared with the prior art, the utility model has the advantages of following several aspects:
the utility model discloses in, will go up the girder steel through setting up the bearing seat and erect unsettledly with girder steel down, when tunnel ground construction concreting, with the bearing seat setting at both ends, pour concrete from built on stilts position, personnel's operation equipment all passes through from the girder steel after pouring the completion, has avoided causing destruction to the concrete of pouring, and simultaneously when the ground clearance of girder steel is adjusted to needs, the hydraulic stem realize the lift of girder steel fixing base can, promote the use flexibility ratio.
The utility model discloses in, when appearing that ground is harder or be stained with water and easily slide, will cup joint the seat and install the awl tooth that cup joints the seat bottom in slope steelframe bottom and tightly imbed ground, increase frictional force, promote stability through the bolt.
The utility model discloses in, through setting up settlement monitoring device on the girder steel, adopt the cooperation of pointer and scale, simple structure easily observes the use, judges subsiding of girder steel through observing the displacement of pointer on the scale to this judges whether hydraulic stem work is normal, needs the maintenance to change, avoids the chronic reduction of hydraulic stem hydraulic pressure ability and can not in time discover, and the condition that influences the operation safety takes place.
