[0002] In slope buildings, one or more sides are often adjacent to the soil, so it is necessary to set up a retaining wall on the outside of the building. When designing a retaining wall, if the retaining wall and the main building are an integrated structure, the main building and the retaining wall system are relatively complex, and the overall design parameters are difficult to control. Therefore, a separate structure can be used between the retaining wall and the main building to reduce the difficulty of design.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0030] Example
[0031] Refer to the attached drawings of the specification, such as Figure 1-Figure 7 As shown, a retaining wall pressure relief structure separated from the main body of the building, the main body of the building 1 includes a top plate 12, a frame beam 13, a frame column 14 and a second chassis 15. The frame column 14 is vertically arranged, the frame column 14 is located below the top plate 12, the top surface of the frame column 14 is in contact with the bottom surface of the top plate 12, and the bottom of the frame column 14 passes through the second chassis 15. A frame beam 13 is arranged at the contact position between the frame column 14 and the top plate 12, and the frame beam 13 is arranged horizontally. The frame beam 13 can be connected to the frame column 14 and the top plate 12 respectively by mortise and tenon connection, so that the frame column 14 and the top plate 12 are fixedly connected.
[0032] The retaining wall 2 includes a first chassis 21 and a side wall 22. The cross-sectional shape of the retaining wall 2 is "L" or "T", such as Figure 1 , Figure 2As shown. Specifically, when the retaining wall 2 is in a "T" shape, part of the first chassis 21 is located below the second chassis 15, and the first chassis 21 extends rightward to the outside of the building body 1; when the retaining wall 2 is in an "L" shape, the first chassis 21 is completely located below the second chassis 15, and the edge of the first chassis 21 is flush with the edge of the side wall 22. Based on this, the bottom of the frame column 14 continues to extend to the first chassis 21 after passing through the second chassis 15, and is fixedly connected to the first chassis 21. The side wall 22 is located below the edge of the top plate 12, as shown in FIG. Figure 4 As shown, a filling layer 16 is provided at the connection between the top plate 12 and the side wall 22. Specifically, the material of the filling layer 16 can be asphalt hemp.
[0033] Based on the above structure of the building body 1 and the retaining wall 2, a filter layer 3 is provided on the outdoor side of the retaining wall 2. Figure 3 As shown, a filter layer 4 is provided at the bottom of the filter layer 3, a water collecting pipe 5 is provided in the filter layer 4, and a T-tube 6 is embedded in the water collecting pipe 5. Specifically, the filter layer 3 includes a filter cloth 31 and a filter material 32 wrapped by the filter cloth 31, and the filter material can be one or more of pebbles, sand or crushed stones. The construction process of the retaining wall 2 and the filter layer 3 is a prior art known to those skilled in the art. The cross-sectional shape of the filter layer 4 is a right-angled trapezoid that is wide at the top and narrow at the bottom, and its bottom width is greater than the width of the filter layer 3, so that the water passing through the filter layer 3 completely flows into the filter layer 4. The material of the filter layer 4 is crushed stone. By setting the filter layer 3 and the filter layer 4, the silt and soil received by the retaining wall 2 on one side of the slope during the rainy season are filtered, and only rainwater is discharged, and the rainwater is discharged through the water collecting pipe 5. The material of the water collecting pipe 5 can be a plastic pipe or a stainless steel pipe, and the material of the T-tube 6 is a stainless steel pipe.
[0034] At the same time, a drainage ditch 11 is arranged at the bottom of the inner side of the building main body 1, and the middle end of the T-shaped pipe 6 extends through the retaining wall 2 into the drainage ditch 11. When the rainfall is too heavy, the rainwater collected by the water collecting pipe 5 can be discharged through the drainage ditch 11 through the T-shaped pipe 6, thereby achieving pressure relief inside and outside the retaining wall 2 and ensuring the safety of the building main body 1. The opening and closing of the T-shaped pipe 6 is controlled by the control switch 7 located in the drainage ditch 11. Figure 5-Figure 7 As shown, the control switch 7 includes a manual switch 71 and an automatic switch 72, wherein the automatic switch 72 can be a pressure difference type switch. The opening and closing of the T-tube 6 is controlled by the pressure difference on both sides of the switch to achieve automatic pressure relief of the retaining wall 2. An upper cover 111 is arranged above the drainage ditch 11, and the upper cover 111 is detachably connected to the drainage ditch 11, or is only in contact with it.
[0035] In addition, if Figure 3 As shown, a blind ditch 8 is arranged below the water filter layer 4 , and the water collecting pipe 5 can be arranged at the connection between the water filter layer 4 and the blind ditch 8 .
[0036] Based on the above structure, this application has the following advantages:
[0037] 1. The filter layer 3 is arranged outside the retaining wall 2 to avoid occupying the usable space inside the building body 1; a water collecting pipe 5 is arranged on the water filter layer 4, and the water is guided to the water collecting pipe 5 through the filter layer 3, and then guided to the outdoors through the water collecting pipe 5 for drainage.
[0038] 2. A drainage ditch 11 is set in the building body 1, and a T-tube 6 is embedded in the water collecting pipe 5. The T-tube 6 can be controlled by a manual switch 71 and / or an automatic switch 72; the automatic switch 72, such as a pressure difference type switch, can be used to control the opening and closing of the T-tube 6 by setting a pressure difference safety value, so that the water in the water collecting pipe 5 can be discharged through the drainage ditch 11, thereby achieving the purpose of pressure relief and improving the safety of the building.
