The invention relates to a road structure and a construction method thereof. The road structure comprises a sidewalk and a blind lane arranged in the middle of the sidewalk; floor tiles are laid on the sidewalk; blind bricks are laid on the blind lane; protective fences are correspondingly arranged on the two sides of the width direction of the blind lane; the protective fences comprise a plurality of supporting frames and protective pipes, wherein the supporting frames are mounted on the ground, and the protective pipes are inserted in the supporting frames; concrete lanes are arranged between the floor tiles and the blind bricks; a plurality of mounting pipes are fixed in the concrete lanes; the interiors of the mounting pipes are hollow and provided with internal threads; and supportingframes are arranged above the mounting pipes, and fastening bolts matched with the threads of the mounting pipes are arranged on the supporting frames in a penetrating manner. The road structure hasthe effects that the occupation of outside sundries to the blind lane is reduced, and the running safeties of blind people are guaranteed.

The invention discloses a mechanical anti-theft lock applied to a well lid, an unlocking device and the well lid. The mechanical anti-theft lock applied to the well lid comprises a lock shell. A rotatable lock cylinder is arranged in the lock shell in a penetrating manner. The lock cylinder is fixedly connected with a spring bolt. The lock shell is provided with a first opening and a second opening, wherein a set included angle is formed between the first opening and the second opening. The spring bolt is driven by the lock cylinder to rotate to the first opening to be clamped and stopped, and then locking is completed. The spring bolt is driven by the lock cylinder to rotate to the second opening to be clamped and stopped, and then unlocking is completed. The top of the lock cylinder is a convex face. The lock cylinder is provided with at least one convex block in the radial direction around the convex face. The mechanical anti-theft lock applied to the well lid is provided with the two openings, locking and unlocking are completed at the two openings correspondingly, the locking manner is easy to operate, and the locked state or unlocked state is stable. According to the mechanical anti-theft lock applied to the well lid, the top of the lock cylinder driving the spring bolt to conduct unlocking or locking is set to be the convex face, and the convex blocks are arranged around the convex face; and in this way, common tools cannot be matched with the lock cylinder, so that a lock body cannot be unlocked through the common tools, and therefore the anti-theft effect is effectively achieved.

The invention relates to the technical field of building windows, and discloses a theft-proof plastic steel window. The window comprises a plastic steel window frame, a movable groove is formed in thebottom of the plastic steel window frame, and a sliding groove penetrating through the upper end of the inner wall of the plastic steel window frame and communicated with the movable groove is formedin the upper surface of the inner wall of the plastic steel window frame; a first bearing is fixedly connected to the upper surface of the inner wall of the movable groove, a first round rod is fixedly connected with the inner wall of the first bearing, and the surface of the first round rod is movably connected with the inner wall of the sliding groove, and a first plastic steel window is fixedly connected with the upper surface of the first round rod. According to the theft-proof plastic steel window, a connecting block is pushed to make the first plastic steel window rotate by taking a second round rod as the circle center, the first plastic steel window cooperates with a second plastic steel window by taking a third round rod as the circle center to rotate so that the first plastic steel window and the second plastic steel window can be folded, and therefore the purposes of thievery prevention and large ventilating areas are achieved.
