Description

Technical Field

[0001] This utility model belongs to the field of jet grouting technology, and in particular relates to an intelligent pressure regulating and flow regulating high-pressure jet grouting construction device. Background Technology

[0002] Jet grouting (also known as jet grouting reinforcement technology) is a commonly used foundation treatment technology, mainly used to improve the bearing capacity of soil or reinforce unstable geological conditions. Its basic principle is to inject cement grout or other solidification materials into the ground by rotating the drill rod to form a pile, so as to enhance soil strength, improve foundation bearing capacity, and limit settlement.

[0003] In jet grouting pile construction, flow velocity and pressure are two crucial factors that directly affect pile quality, reinforcement effect, and construction efficiency. Regarding flow velocity, excessively high flow rates can lead to uneven cement grout distribution, failing to fully fill pores and impacting pile strength and stability. Conversely, excessively slow flow rates can result in low construction efficiency, increasing construction time and costs. As for pressure, higher pressure helps the cement grout penetrate deeper soil layers, improving soil amendment effects, especially in denser or harder soil layers. Insufficient pressure may prevent the grout from fully penetrating or breaking down harder soil layers, leading to unsatisfactory reinforcement results.

[0004] Most existing jet grouting piles cannot adjust pressure and flow rate, which affects construction. In response, this application proposes an intelligent pressure and flow regulating high-pressure jet grouting pile construction device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
