The invention provides construction equipment of a highway well lid peripheral concrete anti-cracking device, and belongs to the technical field of highway construction. The construction equipment ofthe highway well lid peripheral concrete anti-cracking device comprises a rack main body, a rotating assembly, a horizontal assembly, an angle assembly and a drilling and milling assembly, and is characterized in that a power head provides main drilling and milling power, a rotary worktable is fed at a low speed, vibration generated by high-speed rotation of equipment is reduced, the impact on concrete is mitigated, the cracking is reduced, the angle assembly adjusts the milling angle, a well lid mounting pit groove side wall inclined plane and a pit slot bottom boss are synchronously processed, concrete cracking caused by later polishing of an inclined plane angle is reduced, a vertical milling cutter divides the road well lid mounting groove, damage to the well lid mounting groove causedby subsequent hollowing is avoided, the risk of concrete breaking is reduced, one-time clamping and synchronous machining are achieved, the machining efficiency of the well lid mounting groove is improved, the risk of cracking of concrete around a well lid is reduced at the same time, road maintenance is more convenient, and the road maintenance quality is higher.

The invention discloses highway maintenance construction equipment. The highway maintenance construction equipment comprises a shearing mechanism fixing frame and a fiber shearing mechanism, wherein a motor is fixed on a clutch transfer case; one end of a steel wire flexible shaft is connected with the clutch transfer case, and the other end of the steel wire flexible shaft is connected with a driving shaft on a driving rubber wheel; asphalt spraying beams are arranged on the front and rear sides of the fiber shearing mechanism; asphalt spraying control valves are arranged on each asphalt spraying beam and compressed vertically through nuts; the fiber shearing mechanism is fixedly connected to the shearing mechanism fixing frame through a bolt by using a fiber conveying guide pipe; the driving rubber wheel is fastened with the shearing mechanism fixing frame in a half-shaft fixing mode; an upper shielding fan cover and a lower shielding fan cover are respectively fixed on the asphalt spraying beams through bolts; one end of a tension spring is fixed on a fiber shearing mechanism fixing frame; and the other end of the tension spring pulls a shear blade fixing wheel. The reliability of a transmission system is effectively ensured, so the service life of the system is prolonged.
