[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the present invention provides a permanent-temporary combined structure for building water supply, comprising:

[0034] Multiple water collection trenches 2 are all set in low-lying areas on the ground surface. Multiple first cover plates 26 are detachably installed at the top opening of the water collection trenches 2 to cover them. Multiple first filter holes are provided on the first cover plates 26.

[0035] The drainage ditch 1 has a plurality of second cover plates that can be detachably installed at its open top to cover it. The second cover plates are provided with a plurality of second filter holes. The drainage ditch 1 has a plurality of filter tanks 6 that are arranged and spliced ​​along its extension direction and are divided into a filter section 102 and a drainage section 101 arranged vertically. The filter section 102 is connected to the lowest end of each water collection ditch 2, and the drainage section 101 is connected to the water collection pool 3.

[0036] The temporary-permanent combined structure for building water supply provided by this technical solution mainly consists of a drainage ditch 1 and multiple collection ditches 2 connected to it. Each collection ditch 2 is located in a low-lying area on the ground surface. Multiple first cover plates 26 are detachably installed at the top opening of each collection ditch 2. These first cover plates 26 are assembled to cover the top opening of the collection ditch 2. Each first cover plate 26 has multiple first filter holes. The first cover plates 26 are used to intercept large particles such as sand and gravel in the water accumulated at the construction site, preventing them from entering the collection ditch 2. Multiple second cover plates are detachably installed at the top opening of the drainage ditch 1. These second cover plates are assembled to cover the top opening of the drainage ditch 1. Each second cover plate has multiple second filter holes. To intercept large particles of impurities flowing into the water from above the drainage ditch 1, the drainage ditch 1 is detachably equipped with multiple filter tanks 6 for filtering fine particles of impurities in the water. The filter tanks 6 are arranged and spliced ​​along the extension direction of the drainage ditch 1, dividing the drainage ditch 1 into a filter section 102 and a drainage section 101 arranged at the top and bottom. The filter section 102 is connected to the lowest end of each water collection ditch 2, and the drainage section 101 is connected to the water collection tank 3. After the water in the water collection ditch 2 flows to the filter section 102, it is filtered again by the filter tanks 6 and then flows to the drainage section 101, and then to the water collection tank 3. The water collection tank 3 is connected to a water pump through a connecting pipe extending to its bottom, and the water in the water collection tank 3 is transported to various places through the water pump and the drain pipe for use in construction, watering flowers, etc.

[0037] The drainage and water conveyance process of the building water conveyance permanent and temporary combined structure provided by this technical solution is as follows: rainwater and sewage at the construction site flow along the ground surface to the water collection ditch 2 in the low-lying area. Large particles such as sand and gravel are intercepted outside the water collection ditch 2 by the first cover plate 26. The water flows along the water collection ditch 2 to the filter section 102 of the drainage ditch 1. Fine particles are intercepted in the filter section 102 by the filter tank 6. The water flows to the drainage section 101 and flows along the drainage section 101 into the water collection pool 3.

[0038] The water in the collection tank 3 can be reused for construction, watering plants, and dust suppression. Construction workers can periodically open the first cover plate 26 and the second cover plate to inspect and clean the collection ditch 2 and the drainage ditch 1.

[0039] The present invention includes at least the following beneficial effects: A plurality of first cover plates 26 are provided at the top opening of the water collection ditch 2 to cover it; the first cover plates 26 are provided with a plurality of first filter holes; a plurality of filter tanks 6 arranged and spliced ​​along its extension direction are detachably provided in the drainage ditch 1, dividing it into a filter section 102 and a drainage section 101 arranged vertically; the filter section 102 is connected to the lowest end of the water collection ditch 2; the drainage section 101 is connected to the water collection tank 3; surface water flows to the water collection tank 3 through the first filter holes, the water collection ditch 2, the filter section 102, the filter tanks 6, and the drainage section 101. The drainage and water conveyance process does not require the use of a water pump. The water first passes through the first cover plate 26 to filter out large particles of sand and gravel, which can prevent the water collection ditch 2 from being blocked. Then, it passes through the filter tank 6 to filter out fine particles of impurities, making the water cleaner so that the water in the collection tank 3 can be reused. The first cover plate 26 is detachably installed at the top opening of the water collection ditch 2, and the second cover plate is detachably installed at the top opening of the drainage ditch 1, which facilitates the cleaning of the water collection ditch 2 and the cleaning and maintenance of the inside of the drainage ditch 1. The filter tank 6 is detachably installed inside the drainage ditch 1, which facilitates the disassembly and replacement of the filter tank 6.

[0040] In another technical solution, such as Figure 1 , Figure 3 As shown, the permanent-temporary combined structure for building water supply also includes: multiple water supply pipes 15, the top of each water supply pipe 15 being connected to the rainwater outlet 20 on the roof of the building 5, and the bottom being connected to its corresponding water collection ditch 2. After the building 5 is built, the accumulated water on the roof flows through the rainwater outlet 20 to the water supply pipes 15 and then to the water collection ditch 2 for collection and reuse, thus saving water resources. A net can be installed at the rainwater outlet 20 to intercept large particles of impurities. The water collection ditch 2 and the drainage ditch 1 can be used permanently from the start of construction, while the water supply pipes 15 are used after the building 5 is completed.

[0041] In another technical solution, such as Figure 1 , Figure 3 As shown, in the permanent-temporary combined structure for building water supply, the top of the water supply pipe 15 is funnel-shaped.

A third filter hole is provided on the top cover 4. The top cover 4 prevents debris from entering the water supply pipe 15. A spring 21 is clamped between the top cover 4 and the wall of the building 5 near the hinge point. One end of the spring 21 is connected to the wall, and the other end is a free end supporting the top cover 4. When rainwater drips onto the top cover 4, it vibrates under the elastic force of the spring 21, shaking off the debris adhering to the top cover 4. The top cover 4 can be opened to inspect the inside of the water supply pipe 15.

[0042] In another technical solution, such as Figure 3As shown, in the temporary and permanent combined structure for building water supply, a rotating shaft 18 coaxially mounted inside the water supply pipe 15 is rotatably mounted via a support 19. Multiple spirally arranged rotating blades 17 are provided around the rotating shaft 18, and a scraper 16 parallel to it is also mounted on the rotating shaft 18. The scraper 16 has bristles near its edge on the inner wall of the water supply pipe 15. Water flows into the water supply pipe 15 and falls onto the rotating blades 17, causing the rotating shaft 18 to rotate (similar to a windmill), which in turn drives the scraper 16 to rotate, allowing the bristles on the scraper 16 to clean the inner wall of the water supply pipe 15. Alternatively, the rotating shaft 18 can be manually rotated to agitate the water supply pipe 15 with the scraper 16 and bristles to prevent blockage.

[0043] In another technical solution, such as Figure 3 As shown, in the permanent-temporary combined structure for building water supply, a filter box 14 is provided between the water collection ditch 2 and the water supply pipe 15. A limiting cylinder is provided on the top of the filter box 14, and a water inlet is provided on the top wall of the filter box 14 inside the limiting cylinder. The bottom of the water supply pipe 15 is inserted into the limiting cylinder. A pull-out hole is provided on the side wall of the filter box 14, and a filter drawer 13 is inserted into the pull-out hole. A water outlet hole is provided at the bottom of the filter drawer 13, and a filter layer is provided inside the filter drawer 13. A water outlet hole is provided on the bottom wall of the filter box 14. The water supply pipe 15 can be connected to the wall of the building 5 via a fixing bracket. The limiting cylinder is used to connect and restrict the relative position of the water supply pipe 15 and the filter box 14. The filter drawer 13 is easily disassembled and installed via the pull-out hole. Water flowing from the roof flows into the filter box 14 after passing through the water supply pipe 15, and then flows into the water collection ditch 2 after being filtered by the filter drawer 13.

[0044] In another technical solution, such as Figure 3 , Figure 4 As shown, in the permanent-temporary combined structure for building water supply, the bottom of the water collection ditch 2 is provided with a water collection trough 22, and multiple sets of upper and lower spliced ​​support plates 24 are provided on the side wall. The top of the water collection trough 22 is provided with multiple first connecting slots. The top of the support plate 24 is provided with a second connecting slot, and the bottom is provided with a first connecting block 23. The bottom of the first cover plate 26 is provided with a second connecting block 25. The second connecting block 25 is inserted into the second connecting slot on the uppermost support plate 24. The first connecting block 23 of the uppermost support plate 24 is inserted into the second connecting slot on the support plate 24 below it. The first connecting block 23 of the lowermost support plate 24 is inserted into its corresponding first connecting slot. The water collection trough 22, multiple support plates 24, and multiple first cover plates 26 are assembled by inserts and slots to form the internal water conveyance structure of the water collection ditch 2. It is flexible to disassemble and assemble and adapts to water collection ditches 2 of different heights and lengths. The first cover plate 26 is provided with a storage groove, and a handle is hinged in the storage groove to accommodate it. Pulling the handle makes it easy to disassemble the cover plate.

[0045] In another technical solution, such as Figure 3 , Figure 5 As shown, in the permanent-temporary combined structure for building water supply, the filter tank 6 is U-shaped. Adjacent filter tanks 6 are connected by U-shaped connectors 28. Both ends of the connector 28 are provided with connecting grooves 27. Adjacent filter tanks 6 are respectively inserted into the two connecting grooves 27 of the same connector 28. The sidewall of the connecting groove 27 is locked to the filter tank 6 inside by screws and nuts 29. To facilitate the assembly and disassembly of the filter tanks 6, the distance between the two filter tanks 6 is such that when one filter tank 6 is inserted into the bottom of its corresponding connecting groove 27, the other filter tank 6 can be pulled out of its corresponding connecting groove 27.

[0046] In another technical solution, such as Figure 3 , Figure 5 As shown, in the permanent-temporary combined structure for building water supply, the top two sides of the filter tank 6 are provided with locking blocks 8, and the side wall of the drainage ditch 1 is provided with limiting blocks 7. The limiting blocks 7 are provided with multiple limiting grooves, and the locking blocks 8 are locked in their corresponding limiting grooves. This restricts the position of the filter tank 6 and installs the filter tank 6 in the drainage ditch 1. A protective layer, such as bricks, can be provided on the side wall of the drainage ditch 1 to prevent soil from falling off the side wall of the drainage ditch 1.

[0047] In another technical solution, such as Figure 3 As shown, in the aforementioned permanent-temporary combined structure for building water supply, the second cover plate includes:

[0048] A support frame 11 is disposed on the top of the water collection ditch 2, and a sliding groove perpendicular to the extending direction of the water collection ditch 2 is provided on the support frame 11.

When the slider 9 slides to the filter plate 12, the movable plate 10 is positioned directly above the filter plate 12 and tangent to its upper surface. Pushing or pulling the movable plate 10, while the slider 9 moves within the sliding groove, causes the stacked portion of the movable plate 10 and the filter plate 12 to overlap or unfold, opening or covering the top opening of the drainage ditch 1. Moving the movable plate 10 towards the filter plate 12 allows for the cleaning of debris from the filter plate 12.
