Embodiment 1

[0029] Such as figure 1 As shown, an asphalt repair vehicle for underwater crack repair of concrete embankments includes a movable vehicle body 1, an adjusting arm 3 that is rotatably arranged on the movable vehicle body 1 and has a telescopic function, and is attached to the adjusting arm 3 The transmission main pipe 2 is provided with balance support cylinders 101 at the four corners of the bottom of the movable vehicle body 1, and the movable vehicle body 1 is stabilized by adjusting the four balance support cylinders 101, and the free end of the adjustment arm 3 is provided with The defect repair cover 4, the defect repair cover 4 includes a circular case with an opening at the bottom to cover the defect of the concrete embankment, the end of the transmission main pipe 2 communicates with the inside of the case, so that the asphalt provided in the transmission main pipe 2 can be transported The pipe 6 extends into the casing, and the asphalt delivery pipe 6 is connected wi...

Embodiment 2

[0032] This embodiment is a further improvement made on the basis of Embodiment 1, as figure 2 and 3 As shown, the asphalt conveying pipe 6 is provided with an asphalt auxiliary conveying mechanism, which includes an air compressor 7 for generating compressed air and a three-way valve 702, which is arranged on the asphalt pump 104 and On the bitumen delivery pipe 6 between the defect repair covers 4, the remaining interface is connected with the compressed air outlet of the air compressor 7, so as to use the compressed air to assist the asphalt delivery in the bitumen delivery pipe 6; The asphalt conveying pipe 6 includes a fluorine rubber inner tube, and a layer of flexible insulation layer 601 is wrapped outside the fluorine rubber inner tube. The flexible insulation layer 601 can be selected from existing insulation materials, and it is required to be flexible so as not to affect the fluorine rubber. The bending of the inner pipe is appropriate; an electric heating wire i...

Embodiment 3

[0034] This embodiment is a further improvement made on the basis of Embodiment 1, as figure 1 , 2 , 4, 5 and 6, the transmission main pipe 2 is also provided with a compressed gas inlet pipe 201 and a fluid discharge pipe 204, wherein one end of the compressed gas inlet pipe 201 communicates with an air compressor 7, and the other end extends into Inside the casing: the fluid discharge pipe 204 communicates the space inside the casing with the outside atmosphere, the compressed air generated by the air compressor 7 is sent into the casing through the compressed air inlet pipe 201, and the water in the casing is The fluid is discharged out of the enclosure through the fluid discharge pipe 204, thereby forming a dry working space within the enclosure.

Abstract

An asphalt repair vehicle for underwater crack repair of concrete embankments, including a movable vehicle body, an adjusting arm that is rotatably arranged on the movable vehicle body and has a telescopic function, and a transmission main pipe attached to the adjusting arm. The free end of the free end is provided with a defect repair cover. The defect repair cover includes a circular case with an opening at the bottom to cover the defect of the concrete embankment. The delivery pipe extends into the casing. The invention uses the telescopic rotation and adjustment function of the adjusting arm to make the defect repair cover cover in the position to be repaired, and then use the asphalt conveying pipe in the transmission main pipe to send asphalt repair material into the defect repair cover to repair the cracks and holes in the concrete embankment. Filling and repairing has realized real-time underwater repairing operations, and can be repaired in time when cracks and holes are found in the embankment, preventing the expansion of cracks and holes, and avoiding potential safety hazards in the embankment.

Description

technical field [0001] The invention relates to concrete embankments in water conservancy facilities, in particular to an asphalt repair vehicle used for underwater crack repair of concrete embankments. Background technique [0002] Water conservancy facilities such as river embankments in the prior art are generally built with cement concrete. Due to some defects in the concrete pouring, such as cracks and holes, these defects will be soaked in water for a long time, which will cause the gap between these cracks and holes. Classes are eroded by water and then enlarged, resulting in surface defects in river embankments and other facilities. Moreover, if a large part of these cracks and holes are underwater for a long time, if they are not repaired in time, the erosion rate will accelerate rapidly under the infiltration of water and the parasitism of algae and underwater microorganisms, causing harm to river embankments and dams. [0003] In order to avoid the occurrence of ...
