Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically to a deep foundation pit grouting device. Background Technology

[0002] In the construction of deep foundation pits in building projects, grouting is an important step, the purpose of which is to reinforce the soil and prevent leakage.

[0003] However, existing deep foundation pit grouting devices are difficult to position and fix during use. Under the complex geological conditions of deep foundation pits, the grouting pipes are prone to displacement, resulting in uneven grouting, affecting the grouting effect and the stability of the foundation pit. Furthermore, the grouting device does not control the grouting pressure and flow rate precisely enough, making it difficult to make flexible adjustments according to different geological conditions and grouting requirements. At the same time, during the grouting process, the grout is prone to sedimentation and blockage of the grouting pipes, requiring frequent cleaning and reducing construction efficiency. Therefore, we propose a deep foundation pit grouting device. Utility Model Content
