[0002] At present, rubble concrete gravity retaining walls are an important form of slope protection for mountain roads. The drainage holes naturally drain the water that seeps out of the soil behind the retaining wall, ensuring the stability of the earthwork, preventing the earthwork from being soaked in water for a long time and collapsing, and ensuring the safety of the retaining wall. Therefore, the positioning and installation of the drainage pipe is one of the key processes in the construction of the gravity retaining wall. The traditional drainage pipe positioning and reinforcement device usually has a circle of springs in the fixed hoop to compress the drainage pipe, and the reinforcement device is directly set up on the wall formwork. This method has the following problems: 1. The drainage pipe is obstructed and intercepted when passing through the ring with a spring, making the installation process difficult and inconvenient; 2. The drainage pipe is not installed firmly and the drainage slope cannot be guaranteed; 3. The drainage pipe will deviate when pouring concrete. Utility Model Content

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] See also Figures 1 to 4 The utility model discloses a positioning and reinforcing device for a drainage pipe of a rough stone concrete gravity retaining wall with an adjustable inclination angle, comprising a reinforcing device 3 mounted on a wall template 11 and a wall back template 12, a plurality of positioning devices 4 being threadedly connected perpendicularly to the reinforcing device 3, a drainage pipe 2 being inserted into a fixing hoop 44 in the plurality of positioning devices 4, and adjusting the position of the positioning device 4 on the reinforcing device 3 to realize the regulation of the vertical position of the drainage pipe 2, wherein the inner wall of the fixing hoop 44 is provided with a plurality of groups of springs 45, and the plurality of groups of springs 45 are arranged along the circumference of the fixing hoop 44. Distributed in a circle, this design can effectively alleviate the impact of the downward pressure of concrete on the drain pipe 2 during the concrete pouring process, buffer the drain pipe 2 in all directions, prevent the drain pipe 2 from shifting due to pressure, and have an all-round shock-absorbing effect, ensuring the stability and safety of the drain pipe 2. A fixing plate 46 is connected to the end of each group of springs 45, and a pull rope 47 is connected to the fixing plate 46. All the pull ropes 47 pass through the fixing hoop 44 and are connected to the annular card 48 arranged on the periphery of the fixing hoop 44.

[0022] Example 1

[0023] In Example 1, the annular card 48 and the fixing hoop 44 are connected by a threaded connection. The outer periphery of the fixing hoop 44 is provided with a larger pitch so as to cooperate with the thread of the annular card 48. By rotating the annular card 48, the pull rope 47 connected thereto can be pulled, thereby compressing the spring 45, thereby leaving a channel for the drainage pipe 2 to pass through. After the drainage pipe 2 successfully passes through the fixing hoop 44, the annular card 48 is rotated in the opposite direction to reset the annular card 48. At this time, the spring 45 will drive the pull rope 47 to reset, thereby causing the spring 45 to clamp the drainage pipe 2 to effectively prevent it from loosening.

[0024] Example 2

[0025] In Example 2, the annular card 48 is sleeved on the outer periphery of the fixing hoop 44, and downward pressure is applied to separate it from the fixing hoop 44. Subsequently, the pull rope 47 moves toward the fixing hoop 44, thereby compressing the spring 45 to provide necessary space for the drain pipe 2 to pass through the fixing hoop 44. Once the drain pipe 2 successfully passes through the fixing hoop 44, we put the annular card 48 back on the outside of the fixing hoop 44 to restore the spring 45 to its original state, ensuring that the end fixing plate 46 of the spring 45 is in close contact with the drain pipe 2, thereby firmly clamping the drain pipe 2 to prevent it from loosening.

[0026] In this embodiment, after the horizontal spacing between the positioning screws 41 is pre-set, the vertical adjustment nut 43 is threadedly connected to the reinforcement device 3 according to the preset horizontal spacing. The horizontal adjustment nut 42 and the vertical adjustment nut 43 are integrally formed and perpendicular to each other. The positioning screw 41 is threadedly connected to the horizontal adjustment nut 42. During the connection process, it is necessary to adjust the position of the positioning screw 41 in the vertical direction to ensure that it forms a uniform inclination angle with other positioning screws 41 as a whole. Then, the fixing hoop 44 is threadedly connected to the positioning screw 41. Finally, by adjusting the vertical distance of the positioning screw 41 on the reinforcement device 3, the up and down movement of the drain pipe 2 can be achieved to meet different installation requirements.

[0027] In this embodiment, the reinforcement device 3 includes a reinforcement nut 31, a reinforcement gasket 32 ​​and a reinforcement screw 33. The reinforcement screw 33 passes through the wall formwork 11 and the wall back formwork 12. The reinforcement gasket 32 ​​is sleeved on the reinforcement screw 33 and abuts against the wall formwork 11 and the wall back formwork 12 respectively, so that the connection between the reinforcement nut 31 and the wall formwork 11 and the wall back formwork 12 is more stable to prevent loosening, thereby reducing the impact force on the position of the drain pipe 2 during concrete pouring, and avoiding the position of the drain pipe 2 from being offset.

[0028] In this embodiment, the inner surface of the fixing plate 46 is provided with anti-slip textures to increase the friction between the fixing plate 46 and the drain pipe 2, further improve the stability of the drain pipe 2 in the positioning device 4, and prevent it from shifting during use.

[0029] The working principle of this utility model:

[0030] When in use, the vertical adjustment nut 43 is threadedly connected to the reinforcing screw 33, and then the positioning screw 41 is threadedly connected to the horizontal adjustment nut 42. During the process, the drain pipe 2 and the fixing hoop 44 are assembled, and the pull rope 47 is moved away from the fixing hoop 44 by pressing the annular card 48 downward or rotating the annular card 48 to compress the spring 45, thereby creating a space for the drain pipe 2 to pass through. The drain pipe 2 is passed through the fixing hoop 44, and the annular card 48 is reset to the periphery of the fixing hoop 44, so that the pull rope 47 is relaxed and the spring 45 passes through. Extrude it so that the fixed plate 46 connected to its end is in close contact with the drain pipe 2, and then the fixing hoop 44 equipped with the drain pipe 2 is threadedly connected to the positioning screw 41. During the connection process, it is necessary to adjust the position of the positioning screw 41 in the vertical direction to ensure that it forms a uniform inclination angle with other positioning screws 41 as a whole. Finally, the reinforcing gaskets 32 are passed through the two sides of the reinforcing screw 33 in turn, and ensure that the reinforcing gaskets 32 are located between the reinforcing nut 31 and the wall. After tightening the reinforcing nut 31, concrete is poured to ensure that the installation position of the drain pipe 2 is stable.

[0031] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
