Abstract

[0027] The following description is used to disclose the present disclosure so that those skilled in the art can implement the present disclosure. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations. The basic principles of the present disclosure defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present disclosure.

[0029] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0030] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0031] Figure 1 FIG. 9 is a schematic diagram of a building 900 according to an embodiment of the present disclosure connected to its underground water collection and drainage system. Figure 1 In the embodiment of the present disclosure, a building 900 such as a villa 91 or a basement 92 of a multi-storey residence is connected to a load-bearing column 82 below, and a load-bearing foundation 81 is provided below the load-bearing column 82 so that the building 900 is spaced above the load-bearing foundation 81.
[0032] The underground water collection and drainage system of the disclosed embodiment is provided between the load-bearing foundation 81 and the basement 92 of the building 900, and is used to drain the groundwater, thereby preventing the groundwater from spreading to the basement 92 of the building 900, thereby preventing the walls of the basement 92 from mildewing and water seepage.
[0033] Figure 2 Schematic diagram of the underground water collection and drainage system according to the embodiment of the present disclosure. Figure 1 and Figure 2 The underground water collection and drainage system of the disclosed embodiment includes a plurality of water collection parts 11. Each water collection part 11 includes a water collection cavity and a water inlet 1101 connected to the water collection cavity is formed on the wall surface. Thus, when the groundwater spreads to the height of the plane where the water collection layer 10 is located, the groundwater can enter the water collection cavity through the water inlet 1101, thereby making it difficult for the groundwater to spread upward.
[0034] Optionally, the water inlet 1101 is located on the upper surface of the water collecting member 11. Thus, when the groundwater spreads to the upper surface of the water collecting layer 10, i.e., the height at which the water inlet 1101 is located, the groundwater will flow into the water collecting cavity through the water inlet 1101 under the action of gravity, making it difficult for the groundwater to remain above the upper surface of the water collecting member 11.
[0035] Optionally, a plurality of water inlets 1101 are formed on the upper surface of each of the water collecting members 11, and the plurality of water inlets 1101 are spaced apart along the axial direction of the water collecting member 11. Specifically, the water inlets 1101 are circular, and the plurality of water inlets 1101 are evenly spaced apart at intervals of 2 m on the same straight line. Thus, the water collecting member 11 has a high water collecting efficiency, and even if one of the water inlets 1101 is blocked, the remaining water inlets 1101 can still collect water and can serve as backup for each other.
[0036] Optionally, a plurality of the water collecting members 11 are arranged horizontally in parallel to form a horizontally arranged water collecting layer 10. Specifically, the water collecting members 11 can be arranged horizontally in rows, or horizontally in columns, or cross-arranged or radially distributed around a center point, etc. All of the horizontal arrangements of the water collecting members 11 are within the protection scope of the present disclosure.
[0037] Of course, it is understandable that the water-collecting layer 10 can be multi-layered, that is, the multiple water-collecting parts 11 are at various heights to form a multi-layer water-collecting layer 10 with different heights. The height positions of the multiple water-collecting parts 11 can also be adjustable to form the water-collecting layers 10 with different heights as needed.
[0038] In some examples, the water collecting member 11 is arranged as a horizontally laid water collecting pipe, the hollow channel in the water collecting pipe is formed as the water collecting cavity, and the upper surface of each water collecting pipe forms a plurality of water inlets 1101. Optionally, the water collecting pipe can extend along a straight line, along a curve, or partially extend in a straight line and partially extend in a curve.
[0039] In some other examples of the present disclosure, the water collection layer 10 can be formed as a water collection trough body, the trough cavity of the water collection trough body is formed as the water collection cavity, and a plurality of water inlets 1101 are formed on the upper surface of the water collection trough body.
[0040] The plurality of water collecting members 11 are connected to the inlet of the drainage pipe 20 , and the outlet 2201 of the drainage pipe 20 is arranged corresponding to the drainage position.
[0041] Therefore, the groundwater collected by the water collection layer 10 can be discharged to the outside through the outlet 2201 of the drainage pipe 20, thereby draining the groundwater of the building 900. Moreover, since the weight of the building 900 is borne by the load-bearing columns 82, the pressure on the underground water collection and drainage system is small. Therefore, the underground water collection and drainage system is not easily damaged and has a long service life.
[0042] Optionally, see Figure 1 The underground water collection and drainage system further includes a water storage pipe 21, a monitor 31 and a pumping member 30. The water storage pipe 21 is respectively connected to the drainage pipe 20 and the plurality of water collection members 11. The monitor 31 is arranged at the connection between the water storage pipe 21 and the drainage pipe 20, and is used to monitor whether water reaches the drainage pipe 20. The pumping member 30 is connected to the drainage pipe 20, and is used to pump out water to drain water when water reaches the drainage pipe 20.
[0043] Therefore, after the groundwater comes out of the water collecting layer 10, the groundwater can enter the water storage pipe 21, and be stored in the water storage pipe 21 before being discharged from the drainage pipe 20, thereby preventing the groundwater from being polluted by the external environment on the ground and being able to automatically and timely pump out the groundwater.
[0044] Specifically, the pumping member 30 can be a pump with a water tank, so that when groundwater enters the drainage pipe 20 and is detected by the monitor 31, the pumping member 30 can be started accordingly according to the situation detected by the monitor 31, so that the pumping member 30 can timely pump out the water entering the drainage pipe 20. Therefore, the underground water collection and drainage system can effectively collect groundwater, which can be used to irrigate flowers and plants, and the entire system is more energy-saving and more environmentally friendly.
[0045] Figure 32 is a schematic diagram of the structure of the water storage pipe 21 according to the embodiment of the present disclosure. Figure 1 and Figure 3 The water storage pipe 21 includes a first water storage pipe 211, a second water storage pipe 212 and a connecting pipe 213. The first water storage pipe 211 extends vertically, and the upper end of the first water storage pipe 211 is connected to the drainage pipe 20. The monitor 31 is a water level monitor and is arranged at the upper end of the first water storage pipe 211. The second water storage pipe 212 extends vertically, and the upper end of the second water storage pipe 212 is connected to the plurality of water collecting parts 11. The connecting pipe 213 is connected to the lower ends of the first water storage pipe 211 and the second water storage pipe 212 respectively. Specifically, the water storage pipe 21 is configured as a U-shaped pipe, so that after the groundwater comes out of the water collecting layer 10, the groundwater will enter the second water storage pipe 212, the connecting pipe 213 and the first water storage pipe 211 in sequence until it reaches the upper end of the first water storage pipe 211. At this time, the water level monitor can timely monitor whether the groundwater reaches the drainage pipe 20.
[0046] Optionally, see Figure 2 The underground water collection and drainage system further includes a first filter layer 40. The first filter layer 40 is formed on the water collection layer 10. Thus, the groundwater that has passed through the water collection layer 10 can enter the water inlet 1101 after filtering impurities through the first filter layer 40, so that the impurities carried in the groundwater can be effectively intercepted by the first filter layer 40, and the water inlet 1101 is difficult to be blocked by the impurities carried in the groundwater during water collection.
[0047] Specifically, the first filter layer 40 includes a first fabric layer 41 and a second fabric layer 42. The first fabric layer 41 is laid on the water collection layer 10, and the second fabric layer 42 is laid on the first fabric layer 41. More specifically, the first fabric layer 41 and the second fabric layer 42 are both geotextiles. Thus, the groundwater that has passed through the water collection layer 10 can filter impurities through the first fabric layer 41 and the second fabric layer 42 in turn, and then enter the water inlet 1101, so that the impurities carried in the groundwater can be intercepted by the first fabric layer 41 and the second fabric layer 42 in turn, and the interception and filtration effect is good.
[0048] Optionally, the underground water collection and drainage system further includes a second filter layer 50. The second filter layer 50 is formed under the water collection layer 10. Thus, when the external conditions change, such as when the groundwater level rises due to rain, the second filter layer 50 can first filter the groundwater, so that the impurities carried in the groundwater can be intercepted by the second filter layer 50, and then the groundwater rising above the water collection layer 10 carries as few impurities as possible, which is conducive to preventing subsequent impurities from clogging the water inlet 1101.
[0049] Specifically, the second filter layer 50 is a filter cloth. More specifically, the filter cloth is a geotextile. Thus, when the groundwater level rises, the filter cloth can first filter the groundwater, so that the impurities carried by the groundwater can be intercepted by the filter cloth, thereby reducing the impurities carried by the groundwater that rises above the water collection layer 10.
[0050] Optionally, the load-bearing foundation 81 is a raft foundation (raft structure). There are multiple load-bearing columns 82, and the multiple load-bearing columns 82 are arranged at intervals on the load-bearing foundation 81. Therefore, due to the good integrity of the raft foundation, the raft foundation can disperse the relatively concentrated pressure borne by the load-bearing columns 82 and then allow the land below it to bear the pressure. Therefore, the system with the above-mentioned load-bearing columns 82 and the load-bearing foundation 81 is not prone to settlement and has good seismic resistance. Therefore, the present disclosure effectively combines the raft structure in the building structure with the underground water collection and drainage system, realizes the controllable rise and fall of the groundwater level, can avoid groundwater erosion of the building structure, and can also be used as a shallow groundwater collection system to realize the recycling of rainwater.
[0051] Optionally, the water-collecting layer 10 is arranged directly above the plurality of the bearing columns 82, and the bearing columns 82 pass upwardly out of the water-collecting layer 10, for example, the bearing columns 82 pass through the gaps between adjacent water-collecting members 11 and extend above the water-collecting members 11. Of course, it is understandable that the water-collecting layer 10 may also be arranged in a space enclosed by the plurality of bearing columns 82.
[0052] See 1 and Figure 2, the underground water collection and drainage system also includes a first soil layer 60. The first soil layer 60 is laid between the load-bearing foundation 81 and the water collection layer 10. Specifically, the first soil layer 60 is laid between the second filter layer 50 and the load-bearing foundation 81. As a result, the system is stable as a whole, and the load-bearing foundation 81 can penetrate a certain depth underground, so that the load borne by the load-bearing foundation 81 can be diffused and distributed in the deep soil underground, and the building can be stably and well supported. At the same time, when the groundwater level rises, the groundwater carries the soil up, and the soil is intercepted by the second filter layer 50, so that the groundwater rising above the water collection layer 10 carries as little soil as possible, and it is difficult for the subsequent soil to block the water inlet 1101.
[0053] Optionally, the underground water collection and drainage system also includes a second soil layer 70. The second soil layer 70 is laid between the water collection layer 10 and the building 900. Specifically, the second soil layer 70 is laid between the first filter layer 40 and the building 900. As a result, the system is stable as a whole, and the load-bearing foundation 81 can penetrate a certain depth underground, so that the load borne by the load-bearing foundation 81 can be diffused and distributed in the deep soil underground, and the building can be stably and well supported. At the same time, before the groundwater that crosses the water collection layer 10 carries the soil and flows downward into the water inlet 1101, the soil can be intercepted by the first filter layer 40, thereby making it difficult for the water inlet 1101 to be blocked by the carried soil during water collection.
[0054] See also Figure 1 and Figure 2 The construction process of the building 900 and the underground water collection and drainage system disclosed in the present invention may include the following steps:
[0055] S1: First, dig a foundation trench, build the load-bearing foundation 81 in the foundation trench, and build the load-bearing column 82 on the load-bearing foundation 81;
[0056] S2: pre-filling part of the soil and compacting it to form the first soil layer 60;
[0057] S3: laying a layer of geotextile on the first soil layer 60 to form the second filter layer 50;
[0058] S4: laying a plurality of water collecting members 11 arranged horizontally and in parallel above the second filter layer 50 to form the water collecting layer 10;
[0059] S5: Laying two layers of geotextile on the water collection layer 10 to form the first filter layer 40;
[0060] S6: Filling soil on the first filter layer 40 and compacting it to form the second soil layer 70;
[0061] S7: pouring a basement floor 83 above the second soil layer 70 and the load-bearing columns 82;
[0062] S8: constructing the building 900 on the base plate 83 .
[0063] Therefore, through the above analysis, it can be known that the present invention can not only bear the load of the building 900 well, but also drain the groundwater, making it difficult for the groundwater to spread to the building 900. Therefore, the bottom wall of the building 900, such as the wall of the basement 92, remains dry, is not prone to water seepage or mold, has good safety and long service life.

The advantages of the present disclosure have been fully and effectively realized.
