Description

Technical Field

[0001] The utility model relates to the field of concrete column reconstruction, in particular to a concrete column grouting device. Background Art

[0002] In the field of urban renewal and renovation of old buildings, the reinforcement and maintenance of concrete columns is a crucial project. In order to improve the safety of these buildings and extend their service life, it is usually necessary to reinforce the damaged concrete columns by grouting. Traditional grouting methods are often bulky, complicated to operate and inefficient, especially in indoor environments where construction space is limited and large mixing equipment is difficult to use, which seriously affects the construction progress and quality.

[0003] Although the existing concrete column grouting devices have solved some problems to a certain extent, there are still some shortcomings. Many devices are only equipped with a single mixing bucket and cannot achieve continuous operation, resulting in interruptions in the grouting process and low construction efficiency. In addition, the mixing and grouting functions of traditional equipment are often separated, requiring multiple transportation of mud, which increases labor intensity and the risk of material waste.

[0004] In response to the above problems, a new type of concrete column grouting device came into being. The device is exquisitely designed and suitable for indoor operation. It is not only equipped with multiple mixing barrels to achieve uninterrupted operation of grouting while stirring the mud, but also has a special grouting lifting frame, which greatly improves the accuracy and convenience of grouting. This design not only optimizes the construction process and reduces the investment of manpower and material resources, but also significantly improves the construction efficiency and quality.
