Road crack pouring device for municipal engineering

Abstract

The invention relates to the technical field of municipal engineering, and discloses a road crack pouring device for municipal engineering, through cooperative use of a negative pressure chamber, a negative pressure fan, a dust suction pipe and dirt shoveling teeth, dirt in cracks is automatically shoveled away before crack pouring, and after the dirt is shoveled away, negative pressure generated by the negative pressure chamber is used for automatic adsorption, so that the cleanliness of the cracks is improved, through cooperative use of a push rod, a limiting plate, a first gear, a moving plate and a liquid storage tank, quantitative discharging is performed during crack filling, through cooperative use of a compaction plate, a vertical rod, a moving block, a pinion and a large gear, during crack filling, the compaction plate is finally used for automatically beating and compacting raw materials subjected to crack filling, slurry is in close contact with a crack conveniently, through cooperative use of the supporting plate, the limiting wheel, the threaded rod and the shell, the limiting wheel is utilized to move along a crack during crack filling, the crack filling can be achieved only by pushing along an approximate position, and deviation of the position of the liquid outlet is avoided.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a road joint filling device for municipal engineering. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. In municipal road construction projects, regardless of whether the cement pavement or asphalt pavement is open to traffic for a period of time, various damages, deformations and other defects will appear one after another. Cracks are the various damages in the road surface. It is one of the most common, most prone and earliest pavement diseases. The appearance of cracks on the pavement not only affects the appearance of the road and the comfort of driving, but also easily expands to cause structural damage to the pavement and shortens the service life of the pavement. Therefore, after cracks appear on the pavement, they should be sealed and repaired in time, otherwise rainwater and other sundries will enter t...

AI Technical Summary

Problems solved by technology

The appearance of cracks on the pavement not only affects the appearance of the road and the comfort of driving, but also easily expands to cause structural damage to the pavement and shorten the service life of the pavement.

Therefore, after cracks appear on the pavement, they should be sealed and repaired in time, otherwise rainwater and other sundries will enter the surface structure and subgrade along the cracks, resulting in a decrease in the bearing capacity of the pavement and accelerated local or piece-by-piece damage to the pavement

[0003] Earlier, the road construction and municipal facilities maintenance departments usually filled the cracks on the asphalt pavement and the expansion joints reserved on the cement pavement by hand pouring. Undoubtedly, this operation method has low work efficiency and workers’ fatigue. The labor intensity is high, the quality of joint filling varies with the experience and responsibility of the constructors, and wastes materials

Although with the advancement of science and technology, there are joint filling machines on the market instead of manual joint filling, but the existing joint filling machines are relatively simple to set up, and the slurry and the gap cannot be compacted during the joint filling process. The quality is affected, and when filling the joints, because the direction of the cracks is not regular, it is usually necessary to manually lift the liquid pipe out to avoid the position of the filling joints from shifting, which is time-consuming and laborious

[0004] Aiming at the deficiencies of the prior art, the present invention provides a road joint filling device for municipal engineering, which has the advantages of accurate filling position and automatic compaction, solves the problem that the existing joint filling device is relatively simple to set up, and ensures the use When the device is in operation, it can quantitatively fill the joints, and during the process of filling the joints, the slurry can be automatically beaten and compacted to improve the effect of joint filling, and avoid the deviation of the slurry from the cracks, and improve the intelligence of the device when it is used
