Description

Technical Field

[0001] This utility model relates to the field of grouting technology, specifically to a grouting filler for sleeve grouting. Background Technology

[0002] A grouting sleeve is an assembly consisting of a specially processed sleeve, matching grouting material, and reinforcing bars. When connecting the reinforcing bars, a fast-hardening, non-shrink grouting material is injected, relying on the bonding and interlocking action between the materials to connect the reinforcing bars and the sleeve. Grouting sleeve joints offer advantages such as reliable performance, wide applicability, and easy installation.

[0003] According to patent authorization announcement number CN114150873B, a grouting device and method for sleeve grouting are disclosed. The grouting device includes a grouting pump and a booster pipe. The grouting pump includes a grouting cylinder, a controller, a fluctuating pressure pump, and a grouting pipe. The controller controls the pumping pressure of the fluctuating pressure pump during grouting, so that the fluctuating pressure pump generates wave-shaped pumping pressures with different amplitudes and / or different frequencies at least three time periods during the grouting process. One end of the grouting pipe is connected to the fluctuating pressure pump, and the other end is connected to the grouting hole of the sleeve, for conveying the grouting material mixture into the sleeve. The booster pipe includes a semi-rigid section, a rigid section, and a support bracket. This invention has the advantages of simple grouting operation and high construction efficiency. By using fluctuating pumping pressure to cause the grouting material mixture to move up and down within the sleeve, vibration is generated, thereby achieving compaction of the grouting material mixture, squeezing out air bubbles, and effectively ensuring the density of the grout.

[0004] However, existing slurry feeders have a mixing mechanism installed inside the slurry tank in order to mix the slurry. The mixing mechanism is mostly fixed, making it difficult to mix and stir at any position inside the slurry tank. Moreover, if the mixing device is set up in a more complex way, it will occupy the internal area of ​​the slurry tank. At the same time, the length of the slurry feeder's delivery pipe is mostly fixed, making it difficult to perform slurry feeding work at different positions. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model connects a motor shaft to the upper end of a telescopic rod and a hanging block to the lower end. The hanging block connects the mixing rod and the mixing block, which facilitates the rotation of the telescopic rod by the rotation of the motor shaft, and then the rotation of the telescopic rod drives the rotation of the mixing rod and the mixing block. It also facilitates the up and down movement of the mixing rod and the mixing block by the telescopic rod, thus facilitating mixing at different locations. In addition, the mixing rod makes left and right contact to scrape the material on the inner wall of the grouting box, which is convenient for cleaning and scraping mud, avoiding waste and avoiding the need for a more complex mixing mechanism that would occupy the internal usable area of ​​the grouting box.

[0015] 2. This utility model connects the lower reinforcing sleeve and the upper reinforcing sleeve by setting a threaded sleeve. When the connecting block is pulled, the threaded sleeve is stretched, which facilitates grouting work at different positions. Moreover, it automatically shrinks when not in use, avoiding the inconvenience of storing a long delivery pipe. Attached Figure Description
