Underground engineering challenges of Philippine customers
The Philippine customer is an engineering company specializing in tunnel construction and foundation reinforcement. The recent subway expansion project requires deep grouting reinforcement under complex geological conditions. The project requires the drilling rig to have high torque, strong penetration, and adapt to humid and dusty environments.
Why did the customer choose the jet grouting drilling rig?
1. Project background requirements
The construction area’s geology consists mainly of clay and sand layers, and traditional drilling rigs are prone to hole collapse and uneven grouting. The customer needs a device that can stably penetrate the strata and accurately control the amount of grouting.
2. Application scenario adaptation
The customer plans to use the jet grout drilling rig to complete the pile foundation reinforcement with a diameter of 1.5 meters and a depth of 30 meters. The equipment needs to be compatible with high-pressure jetting technology to ensure uniform diffusion of the slurry and improve the bearing capacity of the foundation.
3. Feedback and results
The customer said, “The YG jet grouting rig is flexible to operate and maintains efficient operation even in a humid environment. The grouting effect far exceeded expectations, and the construction period was shortened by 20%.”
How does YG provide high-quality grouting rig solutions?
After understanding the needs, the YG team recommended the YG-800 jet grout drilling rig. The equipment is equipped with a high-power engine and an intelligent control system, which can automatically adjust the drilling speed and grouting pressure to adapt to different strata.
Equipment highlights
1. High efficiency: The maximum torque reaches 800Nm, and the propulsion force is 15 tons, which can easily cope with hard soil layers.
2. Durability: The all-steel structure, dustproof and waterproof design, is suitable for the hot and humid climate of the Philippines.
3. Intelligent operation: Equipped with an LCD, real-time monitoring of working status, and reduced human errors.
4. In addition, YG provides customized services, trains operators for customers, and promises 24-hour remote technical support. Customer feedback: “The YG team not only provides equipment but also follows up and debugs throughout the process to ensure smooth construction.”
Jet grouting rig customer feedback
After the project was completed, the customer highly praised the performance of the YGgrouting rig: “The equipment has excellent stability and solved the uneven grouting problem we have faced for a long time. We will continue to cooperate with YG in the future.”
