Abstract: The present application relates to a test structure and a test method for implementing an on-site dry-wet cycle of a large-grain-size rock-soil body. The solution includes: a test site evenly paved with a test material; a test tank arranged in the test site, where two ends of each test tank in a width direction are separated from soil bodies of other test sites by steel plates, and each test tank is provided with a plurality of water permeable holes. The present application can implement an on-site dry-wet cycle test of a large-grain-size rock-soil body, and is suitable for engineering practice.

Abstract: A construction method of fast-setting polymer grouting for rapid control of slope erosion and landslide. This solution includes a landslide control method and a slope erosion control method: sorting out an operation platform; drilling and grouting of polymer high-pressure jet grouting piles on the diseased slope; drilling a row of grouting water interception holes densely on the rear edge of the diseased slope; drilling, on the operation platform, a plurality of anchor holes on the diseased slope; inserting a ground anchor into each anchor hole and performing polymer grouting to form a polymer anchorage body; laying a steel wire gauze on the surface of the diseased slope, and connecting and fixing the steel wire gauze with the tail end of each ground anchor; spraying a two-component expandable polymer grouting material onto the steel wire gauze to form a polymer anti-scour layer; drilling a plurality of planting holes on the diseased slope with a backpack drill through meshes of the steel wire gauze; and filling each planting hole with grass seed mixed nutrient soil. The present invention has the advantages of short construction period, ecological and environmental protection, convenient construction, high strength and strong scour resistance.
