Problems solved by technology

The reason is that the attention paid to repairing damaged markings is too low, and no maintenance concepts and regulations have been formed that are consistent with road maintenance. They rely more on manual experience or conservative methods, regardless of the degree of damage. Dominant hot-melt marking paint, but lack of scientific theoretical basis

Embodiment 1

[0024] A rapid detection device for the degree of damage to marking lines, see Figure 1-5 The rapid detection device for the degree of damage of the marking line includes standard sand, a filling device 4, a collecting device 3, a leveling device and a loading device, and the filling device 4 is an internal hollow square movable detachable frame with openings at both ends, The collecting device 3 is a collecting piece horizontally surrounding the filling device 4, which is used to collect redundant standard sand in the process of filling and leveling. The leveling device has the same size as the inner frame of the filling device 4 and has a grip The flat plate of 6, the upper surface of the leveling device and the two sides of the handle 6 are the loading area 7, the loading device is a plurality of stainless steel blocks, the inside of the filling device 4 frame is filled with standard sand, and the leveling device is used to level the filling device 4 Inner standard sand, t...

Embodiment 2

[0032] The same as embodiment 1, the difference lies in that the horizontal base surface in this embodiment is a complete marking base surface, and the frame of the filling device 4 is screwed together by screws 2 . The standard sand is quartz sand with a particle size of 0.1-0.4 mm. The filling device 4 is a stainless steel metal frame, the collecting device 3 is a stainless steel metal sheet, and the leveling device is a stainless steel metal plate.

Embodiment 3

[0034] With embodiment 2, the difference is that in this embodiment, the length of the outer frame of the filling device 4 is 20 cm, the width is 15 cm, the thickness between the inner frame and the outer frame is 2 cm, and the height of the frame is 5 cm. The frame body is divided into four pieces, and the pieces are screwed together by screws 2, and the screws 2 are M8 screws.

[0035]The collection device is a stainless steel metal collection sheet horizontally surrounded by four isosceles trapezoidal plates spliced ​​around the filling device, and the inner short side size of the two isosceles trapezoidal plates connected to the long side of the outer frame of the filling device is 20 cm. The outer long side measures 46.7 cm and the height is 10 cm; the inner short side of the two isosceles trapezoidal plates connected to the short side of the filling device frame measures 15 cm, the outer long side measures 35.5 cm, and the height is 13.3 cm. The thickness of the collecti...

Abstract

A device and method for quickly detecting the degree of damage to marking lines, including standard sand, a filling device, a collecting device, a leveling device and a loading device, the filling device is an internal hollow square removable frame with openings at both ends, and the collecting device is The collecting piece horizontally surrounds the filling device. The leveling device is a flat plate with the same size as the inner frame of the filling device and a handle on the upper surface. The loading device is a number of stainless steel blocks. The filling device frame is filled with standard sand and leveled. The device is used to level the standard sand in the filling device, and the loading device is movable on the upper surface of the leveling device. The invention can realize the detection of different damage types of marking lines, such as drop, crack and so on. Through the analysis and research on the damage degree of the markings, it can provide reference and decision-making for the maintenance plan of the subsequent markings, realize the scientific selection of the maintenance plan of the markings, and maximize the utilization of the markings. Marking line maintenance costs.

Description

technical field [0001] The invention relates to the technical field of road markings, in particular to a device and method for quickly detecting the degree of damage of markings. Background technique [0002] As a part of traffic safety facilities, marking lines are regarded as "lifelines" and have great safety value. The damage of its area seriously affects the quality of markings, such as retroreflective brightness coefficient, appearance, durability, etc. At the same time, the current market share of hot-melt road markings is dominant, and the maintenance problems it faces are also severe. Because hot-melt road markings are not only in terms of cleaning process or cleaning cost, the damage to the road surface is also Larger and more expensive. In this environment, it is extremely important to choose the appropriate maintenance method. [0003] If the degree of damage to the markings is high, if you choose to spray water-based road markings or spray two-component road m...
