Abstract
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 ex…
