[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. "Buildings" specifically refer to structures with roofs, beams, columns, walls, foundations, and internal spaces that meet people's needs for production, residence, study, and public activities. During their use, buildings are exposed to the outdoors and are subject to environmental damage, leading to cracks, peeling, and other issues. Therefore, regular maintenance is necessary; crack grouting is one such routine maintenance method.

A fixed frame 57 is fixedly connected to the bottom end of the rotating rod 55. The fixed frame 57 is fixedly connected to the interior of the fixed cylinder 1. Cement slurry is fed into the fixed cylinder 1 through the slurry delivery pipe 3. When the conveying assembly 5 is working, the worm gear 53 and the turbine 54 cooperate with the conveying blade 56 to deliver the cement slurry to the conveying pipe 81. Then, the crack is filled through the slurry outlet pipe 83, making the cement slurry delivery more stable and convenient.

[0029] Furthermore, the adjustment assembly 8 includes a conveying pipe 81, which is fixedly connected inside the fixed cylinder 1 and below the fixed frame 57. A fixed plate 6 is fixedly connected inside the fixed cylinder 1 near its bottom. The lower end of the conveying pipe 81 passes through the fixed plate 6 and is fixedly connected to a connector 82. There are several adjustment assemblies 8, which are arranged in a circular array inside the rotating block 4. A slurry outlet pipe 83 is slidably connected inside the rotating block 4.

A knob 84 is fixedly connected below the rotating block 4. The rotating part 85 is snapped into the connector 82. The rotating block 4 is rotated by the sliding ring 10 so that the scale on the main grout pipe 83 is aligned with the scale on the fixed cylinder 1.

[0031] In this embodiment, before using the device, the rotating block 4 is rotated by the sliding ring 10 to align the scale on the main grout pipe 83 with the scale on the fixed cylinder 1. When the spring 72 pushes the positioning block 73 to cooperate with the positioning groove 11, the upper pressure adjustment component 8 causes the rotating part 85 to enter the connector 82. Rotating the knob 84 causes the connector 82 to engage with the rotating part 85.
