Abstract: A new technology of constructing ultra-thin antiseepage walls by polymer injection has been developing. The mechanism of polymer expanding and filling the slot formed by the direct pushing method is studied in this paper. ...

Abstract: The establishment of a cement concrete dielectric constant model is the basic and key technique for applying the electromagnetic wave technology to concrete structure quality testing and internal damage detection. Based ...

Abstract: Polymers play a crucial role in modern construction, particularly in the context of underground engineering structures. Foamable polymer (FP) is commonly used for grouting to remediate civil engineering construction. The ...

Abstract: Considering foam’s expansive characteristics and using programming language, the level set method was used to simulate the polymer injection process that forms a thin wall; the influencing factors of the wall formation ...

Abstract: This research presents a practice for quick treatment of voids in airport concrete pavements. Through combining two nondestructive test technologies, heavy weight deflectometry and ground penetrating radar, and polymer ...

Abstract: In order to overcome the disadvantages of high computational complexity and inconvenience when forecasting deformations of surrounding rock by using support vector machine of standard form (Vapnik SVM), a new deformation ...

Abstract: Polyurethane grouting can be used for antiseepage and reinforcement in underground construction. Understanding the diffusion characteristics of polyurethane grout is critical for good grouting design. However, the influence ...

Abstract: Polyurethane grouting technology has been applied in the maintenance and reinforcement of transportation infrastructure such as airports, expressways, and high-speed railways. For rigid pavements with voids underneath ...
