fix spring self and particle ferry

hello dear users
I want to use fix spring self for my walls in a flow simulation, but distance between the wall particles is larger than atomic diameter and my particles pass from the wall. how can I remove this problem?
thanks alot

I dont want to use wall reflect, Can I solve my problem by using bond between wall particles or some simplest way?
thanks alot
