A water retaining structure is provided at the end of the first cable trench 2 close to the cable transfer well 1, and a water retaining structure is provided at the end of the second cable trench 3 close to the cable transfer well 1. The water retaining structure is used to prevent the accumulated water in the first cable trench 2 and the second cable trench 3 from entering the cable transfer well 1. The first cable trench 2 is connected to the drainage structure, and the accumulated water in the first cable trench 2 is drained through the drainage structure after being gathered, and the accumulated water in the second cable trench 3 is naturally drained due to its own slope after being gathered.
[0031] Furthermore, the width and depth of the cable transfer well 1 are larger than the first cable trench 2 and the second cable trench 3. To meet the needs of maintenance and installation, the bottom plate of the cable transfer well 1 is 1.5m to 2m lower than the bottom plate of the cable trench.
[0032] Furthermore, a groove 4 is provided on either side of the bottom plate of the first cable trench 2 and the second cable trench 3. Since the cover plates of the first cable trench 2 and the second cable trench 3 cannot be completely sealed, rainwater will enter the first cable trench 2 and the second cable trench 3. At this time, the groove 4 serves to collect and drain the accumulated water in the cable trench.
[0033] In some embodiments, the water retaining structure includes a retaining ridge 11, which is arranged in the cable trench near the cable transfer well 1. The retaining ridge 11 is cast with plain concrete. The width of the retaining ridge 11 is 10 cm to 20 cm, and the height of the retaining ridge 11 is 20 cm to 30 cm.
[0034] In some embodiments, the drainage structure includes a drainage pipe 6 and a drainage ditch 5 , wherein a first end of the drainage pipe 6 is connected to the first cable ditch 2 , and a second end of the drainage pipe 6 is connected to the drainage ditch 5 .
[0035] Furthermore, the length of the drain pipe 6 is controlled by the elevation of the end point of the drain pipe 6 being lower than the elevation of the bottom plate in the first cable trench 2, so that the accumulated water in the first cable trench 2 can flow to the drain ditch 5 through the drain pipe 6 and be further drained through the drain ditch 5. If the buried position of the first end of the drain pipe 6 is connected to the concave groove 4 of the first cable trench 2, the length of the drain pipe 6 is controlled by the elevation of the end point of the drain pipe 6 being lower than the elevation of the concave groove 4 in the bottom plate of the first cable trench 2.
[0036] Furthermore, grates 7 are installed at both ends of the drain pipe 6 to prevent the pipe from being blocked by debris. In this embodiment, the diameter of the drain pipe 6 is between 75 mm and 150 mm. Specifically, the number of drain pipes 6 is arranged as a single or multiple drain pipes 6 according to actual drainage needs.
[0037] In some embodiments, the permeable structure includes an infiltration pit 8, a coarse sand layer 9 and a pebble layer 10. The infiltration pit 8 is provided at the corner of the bottom plate in the cable transfer well 1, and the bottom plate of the cable transfer well 1 is sloped toward the infiltration pit 8 as a whole, so as to facilitate the collection of water. A coarse sand layer 9 is laid in the infiltration pit 8, and a pebble layer 10 is laid on the top of the side sand layer, and the good water permeability of coarse sand and pebbles is utilized to facilitate the water to infiltrate into the soil at the bottom.
[0038] Furthermore, in this embodiment, the plane size of the infiltration pit 8 is 50 cm to 80 cm, the depth of the infiltration pit 8 is 20 cm to 30 cm, the thickness of the coarse sand layer 9 is 20 cm to 30 cm, and the thickness of the pebble layer 10 is 10 cm to 20 cm.
[0039] Embodiment 2:
[0040] Combination Figures 1 to 3As shown, this embodiment is a drainage arrangement structure of a cable transfer well, including a cable transfer well 1, a water retaining structure, a drainage structure and a water permeable structure, wherein the drainage structure includes a drainage pipe 6 and a drainage ditch 5. Figure 1 As shown, in this embodiment, a cable trench is provided on one side of the road, and a drainage ditch 5 is provided on the other side of the road. The road, the cable trench and the drainage ditch 5 are all arranged in a slope. The cable transfer well 1 is provided in the middle of the cable trench. The cable trench on the upstream side of the cable transfer well 1 is the first cable trench 2, and the cable trench on the downstream side of the cable transfer well 1 is the second cable trench 3. A water retaining structure is provided at the end of the first cable trench 2 and the second cable trench 3 near the cable transfer well 1, and the water retaining structure is used to prevent the water accumulated in the first cable trench 2 and the second cable trench 3 from entering the cable transfer well 1. The first cable trench 2 is connected to the drainage ditch 5 through the drainage pipe 6, so that the water accumulated in the first cable trench 2 is guided to the drainage ditch 5 through the drainage pipe 6, and further drained through the drainage ditch 5, while the water accumulated in the second cable trench 3 can be drained by gravity due to its own slope. The permeable structure is provided at the inner bottom of the cable transfer well 1, and the permeable structure is used to make the water accumulated in the cable transfer well 1 seep into the bottom soil.
[0041] Furthermore, in this embodiment, the width and depth of the cable transfer well 1 are larger than the cable trench, and the bottom plate of the cable transfer well 1 is 1.5m to 2m lower than the bottom plate of the cable trench to meet the requirements of maintenance and installation. Specifically, the cable trench, drainage ditch 5 and cable transfer well 1 are all cast with concrete.
[0042] Furthermore, a concave groove 4 is provided on one side of the bottom plate of the first cable trench 2 and the second cable trench 3. Since the cable trench cover cannot be airtight, when rainwater enters the cable trench, the concave groove 4 is convenient for collecting and draining the rainwater in the cable trench. The water retaining structure includes a retaining sill 11, which is arranged in the cable trench near the cable transfer well 1. The retaining sill 11 can prevent rainwater in the cable trench from entering the cable transfer well 1. The retaining sill 11 is usually cast with plain concrete, and the width of the retaining sill 11 is 10cm to 20cm, and the height of the retaining sill 11 is 20cm to 30cm.
[0043] Furthermore, the arrangement of the drain pipe 6 is as follows: the drain pipe 6 is buried in the concave groove 4 of the first cable trench 2 to the drain ditch 5 on the other side of the road. In combination with the slope of the road itself, the length of the drain pipe 6 is controlled by making the elevation of the end point of the drain pipe 6 lower than the elevation of the concave groove 4 of the bottom plate of the first cable trench 2, so as to ensure that rainwater in the first cable trench 2 can flow through the drain pipe 6 to the drain ditch 5, and further drain through the drain ditch 5. Both ends of the drain pipe 6 are installed with grates 7, which can prevent the pipeline from being blocked by debris. The diameter of the drain pipe 6 is usually between 75 and 150 mm. The number of drain pipes 6 arranged can be combined with actual drainage needs, and can be arranged as a single or multiple drain pipes 6.
[0044] Furthermore, the permeable structure includes an infiltration pit 8, a coarse sand layer 9 and a pebble layer 10. An infiltration pit 8 is provided at the bottom of the cable transfer well 1. The infiltration pit 8 is located at a corner of the bottom plate of the cable transfer well 1. The bottom plate is sloped toward the infiltration pit 8 as a whole to facilitate the gathering of water. A coarse sand layer 9 is laid in the infiltration pit 8, and the thickness of the coarse sand layer 9 is 20cm to 30cm. A pebble layer 10 is laid on the surface layer, and the thickness of the pebble layer 10 is 10cm to 20cm. The coarse sand and pebbles both have good water permeability, so that the sporadic leakage water in the cable transfer well 1 can infiltrate into the soil at the bottom, thereby ensuring that there is no water accumulation in the cable transfer well 1, ensuring that the cable has good operating conditions, and also facilitating the staff to go down to the cable transfer well 1 for maintenance operations. Specifically, the plane size of the infiltration pit 8 is usually about 50cm to 80cm, and the depth size is about 20cm to 30cm.
