[0023] In the specific implementation process, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the sand-draining structure 4 also includes a joint 42, a pipe 43, a sand-draining tube 44 and a waterproof pad 45. The joint 42 is fixed to the side walls of the connecting pipe 41 at both ends, the pipe 43 is fixedly connected to the bottom end of the connecting pipe 41, the sand-draining tube 44 is installed at the bottom end of the connecting pipe 41, and the waterproof pad 45 is fixed to the side wall of the sand-draining tube 44; the connecting pipe 41 is U-shaped, and the connecting pipe 41 and the drain pipe 33 are connected through the joint 42, and the displacement of the connecting pipe 41 is the same as that of the drain pipe 33; the pipe 43 is communicated with the interior of the connecting pipe 41, and the sand-draining tube 44 is threadedly connected to the pipe 43, and the waterproof pad 45 is clamped between the connection point of the pipe 43 and the sand-draining tube 44; the sand-draining tube 44 is communicated with the interior of the connecting pipe 41, and the sand-draining tube 44 is at the bottom end of the U-shaped vertical pipe at both ends of the connecting pipe 41.

[0024] It is convenient to connect multiple sections of the drainage pipe 33 together through the connecting pipe 41, and the water flowing through the connecting pipe 41 can be settled according to its curved section, so that the mud and sand mixed in the book can fall into the inside of the sand discharge tube 44, thereby preventing the mud and sand from being discharged into the underground drainage channel with the water.

[0025] In the specific implementation process, Figure 1As shown, the bottom end of the wall connecting member 1 is fixed to the side wall at the center of the connecting pipe 41, and the connecting pipe 41 is fixedly connected to the bottom surface of the roof 2 through the wall connecting member.

[0026] This facilitates the connecting pipe 41 to be fixedly connected to the wall through the wall connecting member 1 , thereby fixing the position of the connecting pipe 41 .

[0028] The baffle plate 51 is convenient for blocking the silt in the water when the water flows through, so that the silt falls into the interior of the silt discharge tube 44 for collection.

[0029] The working principle of the siphon drainage pipe for buildings provided by the utility model is as follows:

[0030] When in use, first install the water pipe 32 at the drainage position of the roof 2, and fix the siphon drainage bucket 31 on the top of the water pipe 32 so that the siphon drainage bucket 31 is on the surface of the drainage position of the roof 2, and then connect the bottom end of the water pipe 32 to the drain pipe 33, fix the drain pipe 33 to the bottom surface of the roof 2 through the wall connecting member 1, fix the position of the drain pipe 33, and then connect the two adjacent drain pipes 33 through the connecting pipe 41, so that the joint 42 is fixed to the side wall of the connection point of the drain pipe 33 and the connecting pipe 41, and the connecting pipe 41 is also fixed to the bottom surface of the roof 2 through the wall connecting member 1, so that the water pipe 32, the drain pipe 33 and the The connecting pipes 41 are interconnected to form a drainage channel. When it rains, rainwater enters through the siphon drainage bucket 31. When flowing through the connecting pipe 41, it bends in a U shape, which can settle the sand and gravel mixed in the water, so that heavier objects such as sand and gravel can remain in the inside of the connecting pipe 41. The blocking plate 51 fixed inside one end will block other impurities mixed in the water when the water flows through, and prevent them from flowing into the underground drainage channel with the water. After the rain stops and the sky clears, the settled sand and gravel can be cleaned by removing the sand discharge tube 44 from the bottom end thread of the connecting pipe 41, thereby reducing the amount of debris discharged into the underground drainage channel. This device has the advantage of being able to filter fine sand and gravel flowing with the water to prevent them from being discharged into the drainage channel with the water.

[0031] Compared with the related art, the siphon drainage pipe for buildings provided by the utility model has the following beneficial effects:

The sand discharge structure 4 is U-shaped, so that the sand discharge structure 4 can settle the sand and gravel in the water when rainwater flows through, so that the sand and gravel can fall into the bottom end of the sand discharge structure 4 for storage, and the water flows through the bottom end of the sand discharge structure 4. When inside the sand discharge structure 4, since the bottom end of the sand discharge tube 44 is in a closed state, the water inside the sand discharge tube 44 will be in a static state, and the sand and gravel falling into the drainage tube will no longer flow with the water, so the sand and gravel can be stored very well. At the same time, the barrier structure 5 can intercept the water to a certain extent when the water flows, and can reduce the impact of the water while blocking some impurities, which is convenient for rainwater discharge and can greatly reduce the discharge of sand and gravel. This device has the advantage of being able to filter fine sand and gravel flowing with the water to prevent them from being discharged into the drainage ditch with the water.
