The invention relates to the technical field of urban construction, in particular to a kerb and tile visual grabbing control system. A kerb and tile visual grabbing control system comprises a visual identification module, a system control module and a six-axis mechanical arm module, the six-axis mechanical arm module comprises a mechanical arm main body and an auxiliary control assembly, the mechanical arm main body is used for grabbing and laying kerbs and tiles, and the auxiliary control assembly is used for controlling the mechanical arm main body. The mechanical arm body comprises a supporting arm, a lifting arm, a swing arm and a mechanical claw which are sequentially and rotationally connected, and the auxiliary control assembly is connected between the front end of the supporting arm and the front end of the swing arm and used for supporting the mechanical arm body and reducing the equipment load. According to the mechanical arm, the torque generated to the front end of the swing arm when the mechanical claw grabs a heavy object can be effectively shared, the load of each joint motor is greatly reduced, and therefore the structural rigidity and the movement stability of the whole mechanical arm under the heavy-load and large-arm-span working conditions are enhanced, and the precision and stability of the laying action are ensured.

The invention provides a telescopic bridge transition slab structure adapting to fault dislocation and a construction method, and relates to the technical field of bridge engineering.The telescopic bridge transition slab structure comprises a bridgehead transition slab arranged on a fill stratum between a bridge abutment and a roadbed, and the bridgehead transition slab is composed of an upper transition slab and a lower transition slab which are movably connected through a multi-stage energy dissipation type telescopic mechanism; the end, close to the bridge abutment, of the upper butt strap is connected with the bridge abutment through a first hinge anchoring mechanism, and the end, close to the roadbed, of the lower butt strap is connected with the roadbed through a second hinge anchoring mechanism. Through multi-stage energy consumption and hinge release, destructive damage of the structure can be avoided, the basic traffic capacity is maintained, that is, the synergistic effect of all subsystems jointly ensures that after large permanent dislocation is caused by an earthquake, the butt strap structure can still keep the basic form and the supporting function, and the safety of the butt strap structure is guaranteed. And a solid guarantee is provided for critical post-earthquake emergency traffic, and remarkable social and economic benefits are achieved.

This application discloses a sealing structure for seepage paths around a dewatering well, relating to the field of waterproofing technology for construction sites. The structure includes a concrete base slab and a well casing embedded therein. The well casing is cut off from the lower end of the concrete base slab upwards to form a replacement section, which is fixedly connected to the upper opening of the cut-off well casing. The lower end of the replacement section is provided with a lower annular water-stopping wing ring with a water-swellable rubber strip, and the upper end is provided with an upper annular water-stopping wing ring. The upper surface of the upper annular water-stopping wing ring is provided with a cover plate with grouting holes and vent holes. This application, through the cooperation of the replacement section and the upper and lower annular water-stopping wing rings, combined with the water-swellable rubber strip and grouting system, effectively isolates groundwater seepage paths, improves the stability and seepage prevention performance of the well sealing, and protects the waterproofing quality of the main structure.
