The application relates to an improved swelling soil and a preparation method and application thereof, the improved swelling soil comprising 0.4-0.8% of sugarcane residue fiber, 4-8% of biochar, 4% of cement, 0-1.25% of a pH value regulator and 85.95-91.60% of swelling soil to be improved. The application reinforces the soil structure by the sugarcane residue fiber, and restrains the deformation; the biochar is mixed to improve the water stability and structural stability of the soil; the cement is mixed to make the soil sandy and granulated, thereby improving the strength, compactness and stability of the soil; and the pH value regulator is mixed to adjust the acid-base environment of the soil, which is beneficial to subsequent ecological restoration. The application significantly improves the physical and mechanical properties of the swelling soil, effectively reduces the swelling and shrinking potential of the swelling soil, and can make the swelling soil reach an acid-base environment suitable for plant growth. Meanwhile, the solid waste is recycled, waste is turned into treasure, the preparation process is simple and feasible, and the application has good engineering application value.

This invention discloses a pretreatment method for ecological prevention and coordinated emergency response to colluvial deposits and landslide dams on riverbanks. It utilizes mature trees planted vertically at the slope toe, intersecting with horizontally planted mature trees on the slope surface to form a framework of living trees. Simultaneously, waterproof soil bags filled with rock and soil fragments are used to construct soil pillars or walls, providing support for the horizontally planted mature trees. The framework of living trees and the soil pillars or walls together form a retaining structure to prevent potential landslide impacts. The spaces between the soil pillars or walls create a drainage channel for the landslide dam, collectively providing ecological prevention and coordinated emergency response to colluvial deposits and landslide dams on riverbanks. This invention can replace the post-treatment technology of emergency excavation of spillways after landslide dam formation. By pre-constructing the drainage channel before the dam forms, it achieves ecological protection of riverbanks, reduces the risk of landslide damming, and is easy to construct.

This invention discloses a modular gradient purification rain garden system, its monitoring method, and its construction method. Existing rain garden systems generally suffer from non-standard structures and inconvenient assembly. This invention, from top to bottom, includes a permeable paving layer, a bioretention layer, a capillary drainage layer, and a water storage and reuse layer. Each functional layer uses standard modular units, which are connected by stainless steel tenon and mortise connectors. Waterproof rubber sealing rings and bentonite sealing strips are installed at the joints of the standard modular units. Each functional layer is equipped with an intelligent monitoring unit, which includes a turbidity sensor, a pH sensor, a water level sensor, and a temperature sensor. All sensors are connected to a wireless module, and the sensor data is uploaded to a cloud-based prediction platform for centralized processing via a network. This invention improves the flexibility and convenience of rain garden systems during construction, installation, and subsequent maintenance.
