[0019] The present application discloses an integrated drainage device for pre-buried pipes in reinforced concrete retaining walls. A central pipe 2 is provided and pre-buried in a main body 1. An inlet pipe 3 is installed on the side of the central pipe 2 close to the wall back 14. A filter tube 6 is filled inside the inlet pipe 3. Accumulated water enters the drainage device through the inlet pipe 3, enters the central pipe 2 after being removed by the filter tube 6, and is then discharged from the retaining wall through the outlet ends of the drainage pipe 5 and the outlet pipe 4. A roof 7 and a protective net 71 are provided to reduce the possibility of foreign matter clogging the outlet of the outlet pipe 4.
[0020] In order to better understand the above technical solution, Figure 1-5 And specific implementation methods are used to describe the above technical solutions in detail.
[0021] refer to Figures 1 to 3The present application discloses an integrated drainage device for pre-buried pipes in reinforced concrete retaining walls, comprising a main body 1, a central pipe 2, an inlet pipe 3, an outlet pipe 4, and a drainage pipe 5. The main body 1 comprises a concrete layer 11. In the cross section of the concrete layer 11, the portion in direct contact with the supported soil is called the wall back 14; the portion facing the air opposite the wall back 14 is called the wall surface 15; the portion in direct contact with the foundation is called the base 13; and the top surface of the wall opposite the base 13 is called the wall top 12. A central pipe 2 is pre-buried within the concrete layer 11. The central pipe 2 extends from the position of the wall top 12 to the position of the base 13, and from the wall top 12 to the base 13, the radial line of the central pipe 2 gradually tilts toward the position of the wall surface 15. A drainage pipe 5 is fixedly mounted at the lower end of the central pipe 2. The inner wall of the connection between the drainage pipe 5 and the central pipe 2 is curved to improve the smoothness of the connection between the central pipe 2 and the drainage pipe 5. The inclination angle of the drain pipe 5 is greater than that of the central pipe 2, and the angle between the drain pipe 5 and the central pipe 2 is obtuse. The outlet end of the drain pipe 5 penetrates the concrete layer 11 toward the wall 15, and one end of the drain pipe 5 extends beyond the wall 15, connecting to the road drainage ditch. Several inlet pipes 3 are fixedly installed on the outside of the central pipe 2. These inlet pipes 3 are evenly distributed along the length of the central pipe 2 and located near the back of the wall 14. A filter tube 6 is inserted into the inlet pipe 3 to reduce the possibility of water flowing through the soil and entering the central pipe 2. Several outlet pipes 4 are fixedly installed on the outside of the central pipe 2 and opposite the inlet pipe 3. These outlet pipes 4 are also evenly distributed along the length of the central pipe 2, and the connection point between the outlet pipe 4 and the central pipe 2 is lower than the connection point between the inlet pipe 3 and the central pipe 2. The accumulated water enters the water inlet pipe 3 along the water inlet end of the water inlet pipe 3 from the wall back 14 of the main body 1. The filter tube 6 in the water inlet pipe 3 filters the fluid sediment mixed in the accumulated water to reduce the amount of sediment inside the central pipe 2. The accumulated water is preferentially discharged from the drainage pipe 5 at the bottom of the central pipe 2. When the water volume is large, the accumulated water can be discharged from the outlet pipe 4 above the drainage pipe 5. During the drainage process, the air intake cap 8 at the upper end of the central pipe 2 is connected to the external atmosphere of the main body 1 through the through groove 9. In the process of the central pipe 2 draining water outward, the air intake cap 8 intakes air into the interior of the central pipe 2 to balance the air pressure, making the drainage of the central pipe 2 smoother.
[0022] refer to Figure 2 、 Figure 4 and Figure 5The outlet end of the outlet pipe 4 is connected to a cover 7, which includes an insert pipe 75, an upper shield 72, a lower shield 73, side panels 74, and a protective net 71. The insert pipe 75 is threadedly connected to the outlet end of the outlet pipe 4. The end of the insert pipe 75 away from the outlet pipe 4 is provided with an upper shield 72. The lower end of the upper shield 72 is fixedly mounted with side panels 74 symmetrically distributed about the upper shield 72. The side panels 74 are perpendicular to the upper shield 72. The lower end of the side panels 74 is fixedly mounted with a lower shield 73. The area of the upper shield 72 is larger than that of the lower shield 73. The upper shield 72, lower shield 73, and two side panels 74 form a rectangular frame. The protective net 71 is fixedly mounted within the frame. The protective net 71 is fixed to the edge of the insert pipe 75 with bolts. The roof cover 7 is located at the water outlet end of the outlet pipe. After installation, the built-in protective net 71 can reduce the possibility of foreign matter entering the outlet pipe 4 and causing blockage of the outlet pipe 4, and can ensure the drainage effect of the outlet pipe 4. Since the wall 15 of the main body 1 is inclined, the protruding upper cover 72 can reduce foreign matter and water backflow into the outlet pipe 4.
[0023] The working principle of the embodiment of the present application is as follows: the accumulated water enters the water inlet pipe 3 from the water inlet at the position of the wall back 14, and the filter tube 6 in the water inlet pipe 3 filters the liquid sediment mixed in the accumulated water to reduce the amount of sediment inside the central pipe 2. The accumulated water is preferentially discharged from the drainage pipe 5 at the bottom of the central pipe 2. When the water volume is large, the accumulated water can be discharged synchronously from the water outlet pipe 4 above the drainage pipe 5. During the drainage process, the upper end of the central pipe 2 introduces external air into the pipe through the air intake cap 8, thereby reducing the pressure inside the pipe and making the drainage of the central pipe 2 and the water inlet pipe 3 smoother.
[0024] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
