Drilling and Grouting, a Good Cure for Road Diseases
Has the era of "disemboweling" road diseases ended?
Traditional road maintenance often requires large-scale milling and resurfacing, which is not only expensive (70% higher cost), but also leads to long-term traffic interruption and increased risk of pipeline damage. Your problem is: how to cure the base layer voids and cracks without continuous traffic and structural damage?
Our solution - excavation and conversion of road grouting hole Drilling Rigs, combines the flexible chassis of the excavator with professional Drilling Rigs, and becomes Excavator Converted Drilling Rigs. Through the plum blossom-shaped hole arrangement to penetrate the pavement layer, high-pressure cement slurry is injected to make the loose base layer cemented into a "stone body" and restore the continuity of the structure. In actual application, Taiyuan Municipal Government completed the repair of 1,880 square meters of diseases in only 4 days, reducing 8 processes and opening traffic in 6 hours.
Core technology: a revolution of precision and efficiency
1. Flexible drilling: Equipment such as ZLJ-350 supports 0°-360° multi-angle drilling, up to 150 meters deep, and is suitable for Φ50-113mm drill bits, easily penetrating asphalt layers and roadbeds;
2. Intelligent grouting: The grouting pipe does not rotate during static pressure operation to prevent overflow pollution. The slurry ratio and pressure are adjustable, the empty area is accurately filled, and the setting time is controllable;
3. Efficient modification: Based on the rapid deployment of the excavator chassis, the hydraulic system drives the **Drilling And Splitting Machines** functional module to achieve drilling-grouting integration, and the construction efficiency is increased by 60%. Advantages that directly hit the pain points of the industry
Economical efficiency: The cost is more than 20% lower than that of traditional overlays, and the repair of a single crack on Lishui Expressway saves more than 1,000 yuan;
Less interference: Pukou District project verification, 15 minutes of slurry solidification, immediate opening of traffic;
Preventive treatment: 3D radar scanning locates hidden diseases, and the bending settlement value after grouting is restored to the standard, extending the life of the road surface by 5-8 years.
Product Features (Key Features)
1. 360° free drilling: vertical axis Drilling Rig realizes full-angle construction to cope with complex road conditions; 2. Hydraulic precision feeding: 8MPa pressure system stabilizes speed control to avoid secondary damage to the road surface;
3. Modular modification: retain the excavator's walking ability and switch drilling mode in 1 hour.
Construction Tips (Pro Tips)
1. Plum blossom hole layout: hole spacing 1m×1m cross layout to improve slurry coverage uniformity;
2. Radar pre-inspection: geological radar scans the empty area to avoid slurry waste caused by blind drilling;
3. Dynamic parameter adjustment: real-time adjustment of water-cement ratio and pressure during grouting to ensure "filling without overflowing".
Use minimally invasive techniques to treat road diseases - no need to break the road, no long waiting. When the slurry solidifies into rock deep in the roadbed, the traffic has already whizzed by. This is the smart answer to modern road maintenance.
