Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following examples.

[0031] A vacuum joint filling device for pavement cracks, comprising a joint filling machine 1, a vacuum pump 2, a glue filling nozzle 3, a vacuum nozzle 4, a vacuum pad 6, and two pore-blocking pipes 5.

[0032] The glue filling nozzle is connected to the seam filling machine through the glue filling pipe 11. The front end of the glue filling nozzle is provided with a glue outlet head bent at 90 degrees. The glue outlet head is conical and is provided with a glue outlet 31 and a screw thread. The glue outlet is located on the outside of the glue head ( image 3 to the right of the ). The vacuum nozzle is connected to the vacuum pump through a vacuum tube 21. The front end of the vacuum nozzle is provided with a suction head bent at 90 degrees. The suction head is conical and the suction head is provi...

Abstract

The invention belongs to the field of highway and urban road asphalt pavement crack curing, and aims to provide a pavement crack vacuum pouring method. The method has the characteristics of simplicity in operation, no secondary damage and good pouring effect. The invention also provides a pavement crack vacuum pouring apparatus. The apparatus has the characteristics of simple structure, adaption to various cracks, and good pouring effect. The pavement crack vacuum pouring method comprises the following steps: 1) making preparations; 2) cleaning cracks; 3) arranging a vacuum facility and a glue pouring facility; 4) pouring the cracks; and 5) curing. The pavement crack vacuum pouring apparatus is characterized in that the apparatus comprises a crack pouring machine (1), a vacuum pump (2), a glue pouring nozzle (3) connected with the crack pouring machine through a glue pouring tube (11), a vacuum nozzle (4) connected with the vacuum pump through a vacuum tube (21), and a vacuum pad (6) for keeping the vacuum degree of the cracks.

Description

technical field [0001] The invention belongs to the field of maintenance of asphalt pavement cracks of highways and urban roads, and in particular relates to a crack filling method and equipment for early cracks such as small cracks and micro cracks and irregularly shaped cracks. Background technique [0002] At present, the commonly used asphalt pavement joint filling technology is divided into two types: non-grooving method and grooved method. [0003] The non-grooving method is divided into hot operation method and cold operation method. The thermal operation method generally heats ordinary asphalt or modified asphalt to a certain temperature and then fills the cracks in the asphalt pavement. Ordinary hot asphalt joints are prone to high temperature oil flooding and being carried away by vehicles, and low temperature is easy to crack and fall off. Modified hot asphalt has high viscosity and poor flow and permeability, so it cannot fill the cracks full and dense. The fil...
