Injection lances, also known as soil injection lances or soil stabilization lances, are specialized tools used for the injection of stabilizing materials into soil or ground to improve its engineering properties.
The key features and applications of soil lances include:
1. Purpose:
– Soil lances are designed specifically for the injection of grout, cement-based slurries, chemical additives, or other stabilizing materials into the ground.
– The goal is to improve soil strength, reduce permeability, mitigate settlement, or address other geotechnical issues through the injection process.
2. Construction:
– Soil lances typically have a long, slender, and hollow design, allowing for the injection of the stabilizing material through the center of the lance.
– The tip of the lance may be pointed or equipped with specialized features to facilitate penetration into the soil.
– Some soil lances are designed with interchangeable tips or accessories to accommodate different soil conditions or injection materials.
3. Injection Process:
– Soil lances are inserted into the ground, either manually or using specialized equipment, to the desired depth or injection point.
– The stabilizing material is then pumped or injected through the lance, dispersing it into the surrounding soil.
– The injection process is carefully controlled to ensure even distribution and effective soil stabilization.
4. Applications:
– Soil stabilization and ground improvement projects, such as foundation support, slope stabilization, and soil remediation.
– Grouting and sealing of soil voids or underground cavities.
– Injection of chemical additives or grouts for soil remediation or environmental treatment.
– Installation of soil nails, anchors, or other ground reinforcement systems.
5. Specialized Equipment:
– Soil lances are often used in conjunction with specialized injection equipment, such as grout pumps, mixing units, and computer-controlled injection systems.
– This ensures the precise delivery and monitoring of the stabilizing materials during the injection process.
Soil lances are an essential tool in geotechnical engineering and construction, allowing for the targeted and controlled injection of materials into the ground to improve soil properties and address various ground-related challenges.
