Construction equipment of highway well lid peripheral concrete anti-cracking device

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to construction equipment for a concrete anti-cracking device around a road manhole cover. Background technique [0002] Keeping the road smooth is the main task of pavement maintenance. Carrying out road renovation and recovery is not only an important measure for the convenience of pedestrians, but also a necessary measure to ensure the improvement of the quality of road maintenance throughout the year. Due to the repeated rolling of vehicles, the damage of road manhole covers has become the focus of everyone's attention. The manhole cover cutting machine is a road maintenance equipment specially used for circular cutting of cement concrete around manhole covers such as motor vehicle lanes in urban roads. [0003] However, the above-mentioned scheme still has certain defects. The inventor has found through research that the traditional manhole cover cutting machine only...

Problems solved by technology

[0003] However, the above-mentioned scheme still has certain defects. The inventor has found through research that the traditional manhole cover cutting machine only cuts the cylindrical concrete vertically, and the boss at the bottom of the groove and the inclined surface of the groove wall cannot be processed, while the bottom of the road manhole cover needs to be placed In the pits on the surface, it is necessary to quickly install and seal the slopes of the side walls of the pits, all of which require manual grinding and processing. Due to the uneven technical level of the construction workers, the impact force generated by grinding will crack the concrete, increasing the difficulty of road maintenance and reducing Quality of road maintenance
