Description

Technical Field

[0001] The present invention relates to the technical field of municipal construction, and particularly to a pavement construction process and equipment for municipal road engineering. Background Art

[0002] The construction of concrete pavements usually involves multiple layers, mainly including subgrade, base course, cushion course and surface course. Among them, the surface course is the most critical part of the pavement structure, which is mainly composed of concrete materials. In order to ensure the durability and safety of the pavement, strict requirements are imposed on the concrete materials of the surface course, and these requirements include but are not limited to wear resistance, flatness, anti-slip performance and sufficient strength. After the concrete pavement construction is completed, it is necessary to wait for the concrete to completely solidify and then carry out joint cutting. The purpose of joint cutting is to effectively control the generation and expansion of cracks when the pavement is subjected to various stress actions, so as to avoid the damage and fracture phenomena of the pavement caused by stress concentration.

[0003] Since a large amount of dust will appear during the cutting of construction equipment, and the cutting equipment does not have components to suppress the flying of dust, it will pollute the nearby air. Therefore, it is very necessary to propose a pavement construction process and equipment for municipal road engineering. Summary of the Invention

The sliding block is movably connected to the sliding groove. Two ends of the second spring are respectively welded to the sliding block and one inner wall of the mounting frame.

[0010] A circular hole is provided on one inner wall of the mounting frame. A sealing ring is provided on the inner wall of the circular hole. The inner wall of the sealing ring is movably connected to the positioning rod.

[0011] The dust reduction structure includes a water storage tank for storage. A water outlet pipe is fixedly arranged at the bottom of the water storage tank. The other end of the water outlet pipe is fixedly provided with a water pump. The water pump is fixedly connected to the mounting plate. A drain pipe is fixedly arranged on one side of the water pump away from the water outlet pipe. The end of the drain pipe away from the water pump is fixedly provided with an atomizing nozzle.

Under the resilience of the second spring, the positioning rod resets and is inserted into the positioning hole, realizing the positioning of the connecting rod and completing the adjustment of the height of the motor. The third step: Start the motor and the water pump. The motor drives the cutting blade to cut the road surface.
