The application relates to the field of bridge construction, in particular to an assembly type steel tower assembling jig system, which comprises a plurality of jig bodies for supporting a steel tower, the jig body comprises at least two groups of fixed frames arranged side by side and adjusting frames for adjusting the distance between the fixed frames and the steel tower, a plurality of connecting assemblies for connecting the fixed frames and the adjusting frames are arranged between the adjusting frames and the fixed frames, a supporting frame for connecting the top ends of the plurality of adjusting frames is arranged between the adjusting frames, and the supporting frame is in abutment with the surface of the steel tower through the adjusting frames. The application has the effects of reducing the number of height measurements of the jig, simplifying the adjusting process between the jig and the steel tower, and improving the supporting precision of the jig on the steel tower.

The utility model relates to ophthalmic operation technical field discloses a kind of posterior sclera pad pressure implant, including silica gel piece, multiple suture holes are opened in both ends of silica gel piece, storage cavity is opened in silica gel piece, the silica gel piece located at the both sides in storage cavity is also opened and placed inlet, pressure block is movably installed in storage cavity, gasket is movably installed between the bottom of pressure block and storage cavity, the inboard of storage cavity is also coated with ion exchange coating.Place inlet design can place pressure block and gasket before suturing, convenient operation, and pressure block adopts hydrogel, can flexibly adapt to eye demand and cooperate with the silica gel material quality and limit protrusion of gasket, effectively limit pressure block movement, and reduce the pressure of pressure block to eye socket inside, simultaneously, the ion exchange coating in storage cavity, can accurately position hydrogel, improve support accuracy, near macular area Special arc-shaped structure and thickening design, enhanced the pertinence support to macular area, can effectively improve patient eye condition, improve operation effect.

This utility model discloses a steel pipe angle adjustment device for tunnel pipe roof construction, comprising a leveled ground, a tunnel pre-reinforcement zone, a steel pipe, a tunnel face, a steel pipe installation port, and an angle adjustment system foundation, a support system, and an adjustment system. The foundation includes fixing screws, washers, and nuts, with the support system connected to the top. The support system consists of an arc-shaped steel pipe and a transverse plate, which is movably embedded in a brake block. The adjustment system includes a fixing plate, a transverse movable shaft, etc., and the brake block has a fixing groove, etc. Precise adjustment and fixing of the steel pipe angle can be achieved through an angle scale, adapting to different steel pipes, facilitating installation and maintenance, improving construction accuracy and efficiency, reducing safety hazards, and is suitable for tunnel pipe roof construction.
