The application belongs to the technical field of
flood prevention, and discloses a modular assembled
flood prevention retaining wall device, which comprises a
retaining wall in the shape of "L" and hollow.The application is characterized in that a pressure bearing mechanism and an air bag are arranged in cooperation,
water flow impact on the pressure bearing cabin makes the rubber layer deform, the air inside the pressure bearing cabin pushes the air bag to expand outward into the sealing groove, sealing is realized, and the response speed of the air bag is improved, that is, the greater the
water pressure, the greater the force with which the air inside the pressure bearing cabin pushes the air bag to expand outward, and the better the sealing effect, since the air bag is soft as a whole, it can fill the sealing groove more completely, the poor sealing effect of the round corner part of the
retaining wall is avoided, the problem of structural
assembly deviation or insufficient production precision is adaptively compensated, irregular gaps generated after the deformation of the retaining wall due to
water pressure can be filled, the defect that the traditional sealing rubber strip cannot adjust with the change of the gap due to insufficient rigidity is compensated, and the continuous adhesion of the sealing interface is maintained.
