Description

Technical Field

[0001] The utility model relates to the technical field of dam inspection holes, in particular to an inspection hole grouting device. Background Art

[0002] The dam concrete inspection hole is a hole drilled during the construction or maintenance of the dam to check the quality of concrete or the integrity of other structural materials inside the dam. The inspection hole can be used for sampling, detecting cracks or other potential structural problems. After the inspection, grouting backfilling is required. Due to the low viscosity and good fluidity of chemical slurry, chemical slurry can effectively prevent leakage and improve the bearing capacity of the structure. However, the cost of chemical slurry is high. In the prior art, some fillers are often used to fill the borehole to save the use of chemical slurry, such as backfilling the borehole core sample (concrete or rock) and backfilling steel bars (also used as anchor bars), but there are certain shortcomings. When backfilling the borehole core sample, due to the short length of the core sample (usually within 50cm), the friction with the hole wall when filling the borehole is easy to get stuck in the middle of the borehole, making it difficult to fill the borehole; at the same time, it may squeeze or damage the pre-buried plastic grouting pipe and exhaust pipe, affecting the chemical grouting effect. When backfilling the steel bars, using leftover steel bars will have similar shortcomings as backfilling the drilled core samples. Using finished steel bars will result in material waste, and the connection and installation of the steel bars will be time-consuming and labor-intensive. Moreover, the steel bars that also serve as anchor bars may not be completely wrapped by the slurry, thus affecting the anchoring force, failing to achieve the expected effect, and making it more difficult to scan the hole again.

[0003] Therefore, a device is needed that can save chemical slurry while ensuring the backfill effect, ensuring the smoothness of the grouting pipeline, and ensuring the grouting quality. Utility Model Content

After the entire device is plugged in, the gap between the outer wall of the long through tube 206 and the inner wall of the multi-section pipe component 100 is filled with alternative slurry. After the device is extended into the bottom of the borehole, cement slurry and other alternative slurries are poured from the gap entrance between the outer wall of the upper long through tube 206 and the inner wall of the multi-section pipe component 100, saving costs and ensuring the filling quality.
