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 external energy, which is environmentally friendly and does not waste the resources and energy.
