AI Technical Summary
Existing EICP reinforcement technology has problems such as disturbing the soil, poor reaction targeting, and insufficient environmental protection. Especially in the reinforcement of soil around pipelines, traditional methods are prone to mechanical disturbance to pipelines and urease is easily lost, resulting in low reaction efficiency and poor reinforcement durability.
An EICP reinforcement device for the soil surrounding the pipeline is adopted, which uses precision slow-release capsules as the core unit. By embedding porous slow-release modules into the outer wall of the prefabricated pipeline body and filling them with biodegradable water-soluble slow-release capsules, the device uses low-pressure injection to achieve targeted delivery and uniform reaction of urease, generating calcium carbonate crystals to reinforce the soil.
It achieves long-term soil reinforcement without disturbance and in an environmentally friendly manner. It is easy to construct and suitable for new underground pipeline projects, extending the service life of pipelines. The material is biodegradable and does not pollute groundwater.
