In the process of centralized drenching and soaking, the component of the impact force of the water flow sprayed onto the surface of the wall body 10 by the spray head 31 of the first water spraying pipe 3 is downward, the component of the impact force of the water flow sprayed onto the surface of the wall body 10 by the spray head 31 of the second water spraying pipe 4 is upward, namely the component of the impact force of the water flow sprayed onto the surface of the wall body 10 by the first water spraying pipe 3 restrains the upward diffusion of the water flow of the second water spraying pipe 4, so that the water flow of the second water spraying pipe 4 is forced to be accumulated at the superposed water spraying point as much as possible, the impact force of the water flow of the first water spraying pipe 3 and the impact force of the water flow of the second water spraying pipe 4 are balanced with each other, so as to ensure that the water flow of the first water spraying pipe 3 and the superposed water flow of the second water spraying pipe 4 are accumulated at the superposed water spraying point as much as possible, so as to ensure that enough water is enriched at the superposed water spraying point, thereby improving the permeation effect at the superposed water spraying point, and the enriched water is acted by the impact force, the pressure is a certain value, and the pressure further improves the effect of the enriched water permeating into the gaps of the wall body 10, thereby greatly shortening the detection period.
Through the synchronous rotation of bull stick 71 and second trickle 4 to ensure that baffle 73 removes along with the trickle point removal of second trickle 4, make baffle 73 can hold the trickle of second trickle 4 all the time and closely, this holding power has reaction force to the enriched water that closes trickle point department, thereby ensures that enriched water has certain pressure, thereby improves the effect in enriched water infiltration wall body 10 gap.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
