Description

Technical Field

[0001] The utility model relates to the technical field of grouting construction, in particular to a manual grouting gun with adjustable height. Background Art

[0002] In the installation process of precast concrete components, the grouting process is particularly important. The quality and fullness of the grouting determine the firmness of the connection of precast concrete components. Under the existing installation process conditions, large-scale grouting equipment is generally used for on-site grouting. This type of grouting equipment is relatively large in size and weight, and the construction operation is not very convenient. The grouting pipeline is long, and the uneven mixing of the grouting material is prone to pipe blockage, and flushing is inconvenient. At the same time, due to the high pressure itself, it is easy to cause a burst during the grouting process, which brings great trouble to the grouting construction. In addition, it is necessary to make a grouting sleeve joint specimen during the grouting construction. If the automatic device is used to punch the material too fast, the grouting material will be wasted. Based on this, it is imperative to develop a height-adjustable manual grouting gun that is small in size, easy to operate, can meet the grouting construction requirements and the production of grouting sleeve joint specimens, and will not cause a burst.

[0003] Prior art 202320292537.4 discloses a device for sealing a hole through an exterior wall, comprising an electric drill, a material guide trough, a spiral rod and a steel pipe. A material passing hole adapted to a material outlet of the material guide trough is opened on the steel pipe. The steel pipe is connected and fixed to the material guide trough through the material passing hole and the material outlet. One end of the steel pipe is in a sealed state. The spiral rod comprises a smooth section and a spiral section. The spiral rod is arranged in the steel pipe. The smooth section is rotatably connected to the sealing end of the steel pipe, and the smooth section is extended to the outside of the steel pipe for a certain length and then connected to the electric drill for transmission. Although the prior art avoids the use of large grouting equipment, the weight of the concrete is large. During the grouting process, if the handheld device is used, the workers have to bear too much strength. If the workers are physically exhausted after long-term use, the device may fall and injure people. Utility Model Content
