Repair construction method of hardened road surface and house roof crack

Abstract

The invention relates to a hardened pavement and house roof crack restoration apparatus and a construction method thereof. The apparatus comprises a vacuum pump, the gas inlet or gas outlet of the vacuum pump is provided with a gas guide tube, and the tail end of the gas guide tube is provided with a gas guide nozzle; during construction, the gas guide tube is installed at the gas outlet of the vacuum pump, and is inserted to a crack to be cleaned, the vacuum pump is started, and a compressed gas discharged through the vacuum pump cleans dusts in the crack; the cleaned crack is covered with a sealing film to make the sealing film completely cover the crack; and the gas guide tube is installed at the gas inlet of the vacuum pump, the gas guide nozzle at the tail end of the gas guide tube is inserted into one end of the crack, the vacuum pump is started to extract air, waterproof glue is slowly injected to the crack from the other end of the crack, and the waterproof glue flows into the crack under the action of vacuum suction to fill up the crack. The apparatus has the advantages of simple structure, use and operation convenience, long life after restoration and low restoration energy consumption.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a repairing device for repairing cracks in hardened road surfaces and house roofs, which is simple in structure, convenient to use and operate, long in service life after repair, and low in energy consumption. Construction method. Background technique [0002] The current hardened road surface is generally asphalt road surface and cement road surface. Once cracks appear in use, the water on the road surface will seep into the soil foundation under the road surface through the cracks, which will reduce the compressive strength of the foundation and harden the road surface under gravity rolling. be damaged. The damage to the hardened pavement we see is caused by cracks. Therefore, early repair of pavement cracks is an economical, fast and effective way to protect the hardened pavement. At present, the method of hot asphalt liquid pouring is mostly used to repair ...

AI Technical Summary

Problems solved by technology

[0003] Repair, but because the interface between the pothole and the original road surface is difficult to handle, it is easy to seep water, causing secondary damage to the roadbed and road surface; in addition, the roofs of existing houses are mostly concrete structures, and cracks will appear after long-term use , resulting in water seepage in the house. At present, the method of pouring hot asphalt liquid is mostly used to repair the cracks of the roof of the house, which consumes a lot of energy. In this way, there is also air in the cracks. It is difficult for the asphalt liquid to fill the cracks during pouring. On the skin, the gaps inside the cracks still exist, so that secondary cracks will appear shortly after being put into use, and the effect is very poor. Such repeated repairs not only take time and effort, but also cause high maintenance costs; Paste waterproof stickers, but the construction of this method is more complicated, and the cost of repair is higher
