Description

Pavement floor tile replacing and repairing device

Technical Field

The invention belongs to the technical field of urban infrastructure maintenance equipment, and particularly relates to a sidewalk floor tile replacing and repairing device.

Background

The brick pavement is made of cement and aggregate as main raw materials by pressurizing, vibrating and pressurizing or other forming processes, and is used for paving concrete pavements such as sidewalks, roadways, squares, warehouses and the like and blocks, plates and the like (hereinafter collectively referred to as pavement bricks) of subway engineering. The surface of the material can be natural or colorful with or without surface layer (material). The surface of the pavement brick has various colors, concave-convex lines or patterns, can be spliced into various patterns, and has higher breaking strength and frost resistance.

Sidewalks are important components of urban roads and are located on two sides of the cross section of the road for pedestrians to pass through. The paving of the sidewalk comprises the process flows of construction of a base layer, a cushion layer, face bricks and the like. Wherein, the mortar is paved before the face bricks are paved, the cleaned base layer is sprayed with water to be wet, then the mortar with the thickness of about 3cm is paved, and the leveling is used according to the virtual height. And then hanging a line according to the design elevation, paving a first row of the sample plate bricks, then fixing the longitudinal line, horizontally moving the transverse line, paving a second row of the sample plate bricks, and paving the second row of the sample plate bricks according to the line and the sample plate bricks in sequence. In the paving process, a special worker is required to continuously check the seam distance, the straightness and smoothness of the seam, the width and uniformity and the flatness of the road plate, and the special worker can adjust and replace the road plate in time when the road plate is unqualified.

The permeable brick for the sidewalk has good water permeability, is particularly suitable for rainy weather in the south, and rainwater is not reserved to permeate into the ground through the brick body. The water permeable bricks have rough surfaces and are anti-skid, and colorful patterns with different styles can be spliced by flexible and ingenious design of different specifications and colors. The floor is particularly suitable for being used in places with dense crowds, such as squares, sidewalks, pedestrian streets, supermarkets and the like, and is an ideal floor decoration material for modern city construction. The surface is rough, and the rainy day is difficult for slipping down, is favorable to people's rainy day trip safety, and reflection of light performance is poor, and the rainy day can prevent surface gathered water and the reflection of light at night, improves the travelling comfort and the security that the vehicle went and pedestrian walked.

However, at present, due to vehicle rolling, random excavation and the like, pavement tiles of a part of road sections in the urban area are frequently damaged. When the floor tile is damaged in rainy days, the floor tile is in 'dark current surge', and muddy water is splashed if a person steps on the floor tile carelessly. In urban areas, a lot of shops and units are parked by vehicles, and the degree of damage of the sidewalk floor tiles in front of the doors is higher.

The invention discloses a city pedestrian road renovating device, which takes the swaying floor tile through a clamping part, rotates a slurry spraying part to the original position of the floor tile to fill a substrate, and finally puts the floor tile back again, the invention leads the floor tile to be more attached to a base surface through refilling cement, solves the problems that the floor tile is easy to sway and accumulate water and brings inconvenience to pedestrians due to overlarge gaps of the floor tile, but has some defects, such as: the ground tile broken into blocks cannot be used, and the flatness of the ground tile after finishing cannot be well solved.
