Detailed Description
The following is combined with the attached drawings. The utility model is further explained.
The utility model provides a wall body transformation structure suitable for old flood prevention wall is formed by 1 concatenation combinations of a plurality of L type breakwater, and stands on old flood prevention wall.
Wherein, the specific structure of the L-shaped water retaining wall 1 is as shown in fig. 1 and 2, two staggered structures 11 capable of being engaged with each other are respectively arranged at two ends of the wall body of the L-shaped water retaining wall 1, and two connecting holes 2 are reserved on the staggered surface of the staggered structures 11
The L-shaped water retaining wall 1 comprises a vertical surface and a horizontal surface. Wherein, two connecting holes 2 are vertically arranged on the vertical surface of the L-shaped water retaining wall 1 in parallel. Two adjacent L-shaped water retaining walls 1 are mutually meshed, combined and installed together and are fixedly connected together through connecting holes 2 by bolts 4.
In addition, in order to prevent water leakage between the joints of the two L-shaped water retaining walls 1, a water-stopping rubber strip 3 is arranged on the staggered structure 11, and the water-stopping rubber strip 3 can expand when meeting water, so that the gaps can be blocked.
