Detailed Description

The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

as shown in fig. 1, the symbols 1-9 in the figure are respectively expressed as: the water retaining wall comprises a retaining wall 1, a pebble reverse filtering layer 2, an interlayer sealing layer 3, a drainage groove 4, a water retaining platform 5, a reinforcing rib 6, a vertical water drain pipe 7, a transverse water drain pipe 8 and a terrace 9.

Example (b): as shown in fig. 1, the gravity retaining wall for reducing running water erosion in the present embodiment includes a retaining wall 1 and a pebble reverse filter layer 2, wherein the retaining wall 1 serves as a retaining structure for rock and soil mass to bear the pressure of the rock and soil mass at the rear side, and the pebble reverse filter layer 2 is disposed at the rear side of the retaining wall 1 for filtering water in the rock and soil mass. An isolation layer 3 for isolating the pebble reverse filtration layer 2 is arranged at the top of the pebble reverse filtration layer 2, and the top surface of the isolation layer 3 is flush with the wall top of the retaining wall 1 so as to ensure that the structure is consistent.

As shown in fig. 1, a drainage groove 4 is provided at the top of the retaining wall 1, and the drainage groove 4 is a groove structure recessed in the wall top of the retaining wall 1 and used for collecting surface water. Survey in drainage groove 4 and be provided with retaining platform 5, change retaining platform 5 and be used for blockking the surface water, avoid the surface water along the inboard wall laminar flow of barricade 1 under.

In this embodiment, the water blocking platform 5 is internally provided with the reinforcing rib 6, one part of the reinforcing rib 6 is of a hook-shaped structure and matched with the structural form of the water blocking platform 5, and the other part of the reinforcing rib is embedded in the wall body of the retaining wall 1, so that the connection performance between the water blocking platform 5 and the retaining wall 1 is enhanced, and the damage of water flow to the water blocking platform 5 is reduced.

As shown in fig. 1, a vertical drain pipe 7 and two horizontal drain pipes 8 are embedded in the retaining wall 1. Wherein, a horizontal drain pipe 8 is arranged at the terrace 9, one end opening thereof is connected with the pebble reverse filtration layer 2, and the other end opening thereof is exposed out of the inner wall surface layer of the retaining wall 1, thereby leading and discharging water discharged by the pebble reverse filtration layer 2. Vertical water drain pipe 7 is connected between drainage groove 4 and this horizontal water drain pipe that is located terrace 9 department, realizes leading of the surface water that assembles in drainage groove 4 and arranges. The other transverse drain pipe 8 is arranged in the middle of the pebble inverted filter layer 2, an opening at one end of the transverse drain pipe is connected with the pebble inverted filter layer 2, an opening at the other end of the transverse drain pipe is connected with the vertical drain pipe 7, and water discharged by the pebble inverted filter layer 2 is further guided and discharged.
