Definition and working principle of high-pressure jet grouting piles
High-pressure jet grouting piles are a commonly used foundation reinforcement method, usually used to deal with loose soil, unstable foundation or foundation that needs to be reinforced. This method forms a reinforced pile body by rotating the drill rod and spraying materials such as concrete into the soil at high pressure. High-pressure jet grouting piles can not only reinforce the foundation, but also play a role in waterproofing and soil improvement.
How to calculate the depth by drill rod
During the construction process of high-pressure jet grouting piles, the drill rod plays an important role. When measuring the depth, you first need to determine the length of the drill rod and insert it into the reinforcement material. Next, mark the drill rod with a level ruler, then pull out the drill rod and measure the distance from the mark to the ground to determine the depth of the reinforced pile.
It should be noted that the length of the drill rod may vary in different situations, so the drill rod should be calibrated before construction. In addition, in order to ensure the reinforcement effect, the depth measurement should be as accurate as possible to avoid deviations.
Applicable scenarios of high-pressure jet grouting piles
High-pressure jet grouting piles are suitable for many different types of foundations, including but not limited to the following situations:
1. The soil is loose or unstable and needs to be reinforced.
2. The foundation needs to calculate the bearing capacity to ensure the safety of the building.
3. The foundation needs to be waterproof, such as in flood control projects.
4. The land needs to be improved, such as in road or railway construction.
In short, high-pressure jet grouting piles are an efficient and reliable foundation reinforcement method. It sprays reinforcement materials such as concrete into the ground by rotating the drill rod to form a reinforced pile body. During the construction process, measuring the depth through the drill rod is one of the important steps to determine the reinforcement effect.
