[0032] Please see the attached Figure 1 , Attachment Figure 2 and attached Figure 5The utility model provides an embodiment: an assembled anti-seepage prefabricated exterior wall, comprising a prefabricated column 1 and a prefabricated wall 3. The outer wall of the prefabricated column 1 is provided with a mounting groove 4. The outer wall of the prefabricated wall 3 is fixedly connected with a protrusion 5. The inner wall of the mounting groove 4 is engaged with the outer wall of the protrusion 5. The outer wall of the prefabricated wall 3 is fixedly connected with an L-shaped block 7 by a second screw 9. The outer wall of the prefabricated column 1 is fixedly connected to the L-shaped block 7 by a first screw 8. A grouting hole 6 is provided on the outer wall of the upper end of the prefabricated column 1. An exhaust hole 18 is provided at the upper end of the prefabricated column 1. A grouting mechanism 2 is provided at the upper end of the prefabricated column 1. The grouting mechanism 2 is used to grout the connection seam.

[0033] Specifically, the prefabricated column 1 serves as the supporting skeleton of the entire wall. Its design fully considers the balance between installation convenience and structural stability. The outer wall of the prefabricated column 1 is designed with a mounting groove 4, which also enhances the connection strength between the prefabricated wall 3 and the prefabricated column 1. The shape and size of the mounting groove 4 are engaged with the protrusion 5 on the outer wall of the prefabricated wall 3, forming a stable and sealed connection method, effectively avoiding the gaps that may appear in the traditional connection method, thereby greatly reducing the risk of leakage. On the outer wall of the prefabricated wall 3, L-shaped blocks 7 are firmly installed by screws 9. These L The L-shaped block 7 not only enhances the stability of the wall, but also becomes an important connecting bridge between the prefabricated column 1 and the prefabricated wall 3. The outer wall of the prefabricated column 1 is tightly fixed to the L-shaped block 7 by screws 8, which improves the overall rigidity and durability of the outer wall. A grouting hole 6 is set on the outer wall of the upper end of the prefabricated column 1, so that the grouting operation can be carried out more accurately and efficiently, ensuring the complete filling and sealing of the connection seam. In order to eliminate the gas that may be generated during the grouting process, an exhaust hole 18 is also opened at the upper end of the prefabricated column 1 to ensure the smooth progress of the grouting operation and the grouting effect.

[0034] Please see the attached Figure 4 The grouting mechanism 2 includes a connecting pipe 201, the outer wall of the connecting pipe 201 is in contact with the outer wall of the grouting hole 6, the top of the connecting pipe 201 is connected to the mortar bucket 202, the top of the mortar bucket 202 is rotatably connected to a V-shaped rod 203, and the bottom of the V-shaped rod 203 is rotatably connected to a U-shaped block 205 through a connecting rod, forming a multi-link linkage structure, which is an existing connection structure form and will not be described in detail. The bottom surface of the U-shaped block 205 is fixedly connected to a pressure plate 204, and the other end of the V-shaped rod 203 is fixedly connected to a pressure rod 206;

[0035] Specifically, the connecting pipe 201 transports the slurry in the mortar bucket 202 to the grouting hole 6. The outer wall of the connecting pipe 201 is tightly connected to the outer wall of the grouting hole 6, which effectively prevents the leakage of mortar during the transmission process and ensures the smooth progress of the grouting process. The mortar bucket 202 is located above the connecting pipe 201, so that the mortar can flow smoothly into the connecting pipe 201. A V-shaped rod 203 is installed on the top of the mortar bucket 202. One end of the V-shaped rod 203 is connected to the top of the mortar bucket 202. The first end is connected to the mortar barrel 202, and the other end is tightly connected to the pressure rod 206. When the pressure rod 206 is pressed down, the V-shaped rod 203 will rotate accordingly, and then drive the U-shaped block 205 and the pressure plate 204 below it to move up and down through the axial connecting rod. The pressure plate 204 will apply a certain pressure to the mortar in the mortar barrel 202. This pressure does not need to be very high to force the mortar through the connecting pipe 201 into the grouting hole 6. The pressure plate 204 fully considers the fluidity of the mortar and can ensure that the mortar flows out smoothly. In order to ensure the smooth downward movement of the pressure plate, a guide structure can be provided between the pressure plate and the mortar barrel.

Drainage trough 13 and drainage trough 2 14 are respectively provided on the outer walls of prefabricated column 1 and prefabricated wall 3. The drainage trough takes into account the flow path of rainwater, effectively guiding rainwater to drain quickly and preventing the erosion of building materials by accumulated water. The outer wall of the drainage trough is also specially provided with a hydrophobic coating 20. The coating has excellent waterproof properties, which can further enhance the drainage effect and extend the service life of the building. A sound insulation layer 15 is provided inside the prefabricated wall 3 to effectively isolate external noise. A reinforcing rib mesh 16 is also provided inside the prefabricated wall 3 to improve the compressive strength and seismic resistance of the wall, providing a strong guarantee for the safety performance of the building. The protective cover 17 plays a role in protecting the connection part from external damage. The U-shaped block 1 22 fixedly connected to the top surface of the mortar barrel 202 is also connected to the fixed column 10 at one end of the V-shaped rod 203 to achieve a rotational connection.
