The utility model discloses a cutting device for power cable processing, which comprises a working table, a first chute is arranged at the top of the working table in a penetrating manner, a driving assembly is arranged at the bottom of the working table, a first screw rod is arranged at the bottom of the working table through the driving assembly, and the surface of the first screw rod is rotatably connected with a fixing plate. The fixing plate is fixedly connected with the workbench, the surface of the first screw rod is in threaded connection with a first moving plate, a clamping assembly is arranged at the top of the first moving plate, an adjusting assembly is arranged at the top of the workbench, a moving frame is arranged at the top of the workbench through the adjusting assembly, and a lifting assembly is arranged at the top of the moving frame. A second moving plate is arranged in the moving frame through a lifting assembly, and a cutting assembly is arranged on the second moving plate. And the cable is cut after being tightened, so that the cable can be kept in a linear state, and the length measurement error caused by bending or loosening of the cable in the cutting process is avoided.

The utility model relates to a road surface thickness detection device for highway engineering, comprising a pedestal comprising a bottom plate and a top plate; a first radial flange is formed at the upper end of the first sleeve, and a plurality of through holes are formed in the first radial flange; the lantern ring is sleeved outside the first sleeve; a second radial flange is formed in the middle of the second sleeve, and a plurality of through holes vertically opposite to the through holes in the first radial flange are formed in the second radial flange; a handle is arranged on the outer wall of the radial flange II; the drilling machine is fixedly connected with the second sleeve, and a drill bit can penetrate out of a lower port of the first sleeve. Each supporting spring set comprises a guide sliding rod and a supporting spring which are matched in a one-to-one correspondence mode; the lower end of the guide sliding rod is fixedly connected with the lantern ring, and the upper end penetrates through each through hole and is provided with a nut; the supporting spring is sleeved on the guide slide bar and two ends of the supporting spring are arranged between the two radial flanges. According to the utility model, the perpendicularity of the drill bit relative to the road surface can be controlled in a labor-saving manner, and the inclination degree of the drill bit can be effectively inhibited.

The invention relates to the technical field of offshore photovoltaic platform foundation pile sinking construction, and discloses an offshore photovoltaic foundation hydraulic pile gripper which comprises a pile gripper body installed on a pile stabilizing platform; and the hydraulic pushing mechanism is arranged at the top end of the pile gripper body and comprises a plurality of hydraulic oil cylinder assemblies which are circumferentially distributed around the central axis of the pile gripper body. According to the offshore photovoltaic foundation hydraulic pile gripper, a hydraulic pushing mechanism arranged at the top end of the pile gripper is cooperatively matched with a limiting mechanism at the top end of the bottom of the pile gripper, a hydraulic oil cylinder body of the hydraulic pushing mechanism can flexibly stretch out and draw back to adapt to steel pipe piles with different pile diameters, and a limiting inserting plate can adjust the position in a limiting fixing base and is locked through a limiting plug pin; the hydraulic oil cylinder body and the limiting inserting plate do not need to be machined or replaced in advance, the hydraulic oil cylinder body and the limiting inserting plate can be rapidly matched with the steel pipe piles of multiple specifications by adjusting the positions of the hydraulic oil cylinder body and the limiting inserting plate, the pile gripper can be matched with the steel pipe piles of multiple different specifications, and the adjusting process is operated.

The invention discloses an assembling method for prefabricated well pieces of a rectangular assembly type open caisson. The rectangular assembly type open caisson comprises a plurality of annular well sections which are sequentially connected end to end in the length direction. Each circumferential well section comprises more than two prefabricated well pieces to form four splicing structures; the splicing process comprises the following steps that firstly, all the prefabricated well pieces are spliced into corresponding circumferential well sections; 2, blade foot ring well sections are assembled; and 3, the blade foot ring well sections are sunk, all the circumferential well sections are spliced on the blade foot ring well sections one by one, and sinking at the corresponding height is carried out after splicing of one circumferential well section is completed till sinking of all the circumferential well sections of the rectangular assembly type open caisson is completed. By means of the method, the rectangular assembly type open caisson can be flexibly disassembled, well piece lightweight transportation, positioning, reliable connection and efficient splicing are achieved, and the structural integrity and the construction quality of the open caisson are improved.
