Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of geotechnical fixation, and particularly relates to a hand-held homogenate grouting barrel for collapsible loess foundation and a grouting machine. BACKGROUND

[0002] The collapsibility of a collapsible loess foundation can cause different degrees of harm to structures, and can cause the structures to settle, crack and tilt greatly, and even seriously affect the safety and use of the structures. Therefore, when structures such as bridges and culverts are built in loess areas, a reliable determination method and comprehensive understanding of the collapsible loess foundation should be obtained, and correct engineering measures should be taken to prevent or eliminate the collapsibility of the collapsible loess foundation. The grouting machine is a commonly used device, and the existing grouting machines are fed through hoppers. During use, the operator needs to pay attention to the amount of remaining material in the hopper and replenish the material at appropriate times, which results in poor convenience of use.

[0003] Cement slurry pressure grouting is increasingly applied to the foundation reinforcement of existing buildings on collapsible loess foundations. By mixing water glass into cement, the setting time is shortened, and the additional settlement of the building caused by grouting is reduced. The existing grouting technology mixes cement slurry and water glass in a certain proportion in a stirring barrel, and then uniformly punches into the loess. This pre-mixing can cause the slurry to set prematurely and block the grouting pipe. Another technology uses a double-liquid grouting pump. Two kinds of liquid are pumped to the top of the grouting steel pipe through two grouting pipes, and then merged into one grouting pipe. This technology cannot control the proportion of the two kinds of slurry, and cannot achieve the required proportion.

[0004] Some patents of cement grouting devices are disclosed in the prior art. The utility model patent with the publication number CN212001121U discloses a cement grouting device, which comprises a storage barrel, a vertical pipe arranged at the lower end of the storage barrel, a rotating shaft penetrating the storage barrel and the vertical pipe, a spiral blade arranged at the lower end of the rotating shaft, a driving motor driving the rotating shaft, and a plurality of stirring paddles arranged at the upper end of the rotating shaft. The stirring paddles are arranged in the storage barrel. The horizontal position of the pipe opening of the vertical pipe is lower than the bottom end of the rotating shaft. The top end of the storage barrel is provided with a grouting port. The pipe opening of the vertical pipe is provided with a grouting nozzle. The grouting nozzle is provided with an anti-backflow assembly. Although the cement grouting device solves the problem that the grouting speed is difficult to control, which causes the cement slurry to be unable to be uniformly grouted into the cracks, the problem of the storage of the pre-mixed slurry setting before grouting still exists. In addition, the device has the problem of insufficient sealing, which cannot guarantee the storage of the internal pressure during stamping.

[0005] Therefore, the inventor has conducted in-depth research on this demand, and thus the present case is produced. UTILITY MODEL CONTENTS
