Underwater concrete void hole repairing equipment

Abstract

The invention relates to the technical field of river levee repairing equipment, in particular to underwater concrete void hole repairing equipment. The underwater concrete void hole repairing equipment comprises a vehicle body, a mechanical arm, a concrete ground pump, a water pump, an air pump, a sealing cover, a motor and a heating device. According to the underwater concrete void hole repairing equipment, river water is isolated from a hole through the sealing cover, the sealing performance of the sealing cover is improved through cooperation of a sealing air cushion and an elastic sealingcushion, river water is prevented from permeating during hole repairing, underwater holes can be effectively repaired, in addition, air bubble gaps existing in the repairing process are eliminated through pressurization of the air pump, so that cement and the holes have the good combination degree, the practical significance and popularization value are achieved, and it is expected that good economic benefits can be generated.

Description

technical field [0001] The invention relates to the technical field of river bank repairing equipment, in particular to an underwater concrete voiding hole repairing equipment. Background technique [0002] River embankments refer to water retaining structures built along rivers, channels, lakes, coasts or flood diversion areas, and on the edge of reclamation areas. Called flood control embankment, it is the most extensive form of flood control engineering at present. In addition, river embankments can also prevent river water from eroding soil through capillary action. Rigid materials such as mortar masonry or dry masonry stone, cast-in-place or prefabricated concrete are used for slope protection. This kind of slope protection form can well protect the slope of the river, realize the functions of flood discharge, drainage and soil and water conservation of the river, and has the advantages of good stability, land saving, and high degree of construction mechanization.

Problems solved by technology

[0003] Due to the defects existing in concrete pouring, such as air bubbles, holes, etc., these defects will be eroded by river water for a long time after soaking in water, and will gradually expand over time. The erosion rate will be accelerated, making the concrete prone to void areas, which will cause damage to the structure of the embankment

[0004] At present, there is no effective repair method for the holes in the embankment that are hollowed out underwater. The holes above the water level can be repaired by asphalt grouting, and the underwater repair needs to completely empty the water. This method will cause a huge loss of water resources. Waste, in case of dry season or cut-off will cause significant economic losses, if the development of a device that can solve the problem of underwater embankment hole repair will be of positive significance to solve the above problems
