摘要： The present invention discloses a rainfall sensing two-component high-polymer grouting device and a manufacturing method therefor, and belongs to the technical field of soil protection. The present invention includes an iron box and a water bucket. The water bucket is slidably fitted in the iron box. An inner bottom of the iron box is provided with a pair of lever upturning apparatuses symmetrically distributed about an axis center of the iron box. A lower surface of the iron box is provided with a curing agent ejector and a resin ejector. An end of two lever upturning apparatuses is slidably connected to a low surface of the water bucket. The switches of the curing agent ejector and the resin ejector are respectively connected to the other end of a lever upturning apparatus. A peripheral surface of the water bucket is provided with a permeable hole, and a permeable head is installed on the permeable hole. The present invention utilizes the lever principle of natural gravity and the spring-assisted method to realize the function of high-polymer grouting slope protection, and belongs to an ingenious mechanical structure apparatus. There is no need to stimulate and excite from the external energy, which is environmentally friendly and does not waste the resources and energy.

摘要： 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.
