Description

Technical Field

[0001] The embodiments of this utility model belong to the field of basement drainage technology, and more specifically, relate to a basement drainage structure based on BIM. Background Technology

[0002] As a critical underground space, the basement's waterproofing directly impacts building safety, functionality, and lifespan. From a structural safety perspective, continuous groundwater infiltration erodes reinforced concrete, leading to steel corrosion, concrete carbonization and weakening, reducing structural load-bearing capacity, and potentially causing wall cracks and foundation settlement. From a usability perspective, leaks cause water accumulation on the basement floor and mold growth on the walls, rendering storage, parking, and equipment rooms unusable and creating health hazards due to the proliferation of mold and other microorganisms. From an economic cost perspective, repairs to leaks caused by initial waterproofing deficiencies require structural excavation and re-insulation, often resulting in a loss of the original structural integrity.

[0003] Among existing waterproofing technologies, rigid waterproofing lacks sufficient crack resistance, and waterproof concrete is prone to honeycomb-like pitting or cracks due to temperature shrinkage and insufficient vibration during construction. Cement-based penetrating crystalline materials have strict requirements for the dryness of the substrate, and their effectiveness is significantly reduced in humid environments. Flexible waterproofing is highly dependent on construction; the membrane is prone to improper installation at pile heads, corners, and other joints, and its adhesion to the substrate is easily affected by moisture in the subbase, leading to hollow areas. Backfilling operations may also cause damage to the membrane. After the rigid structure cracks, the flexible waterproofing layer often tears due to excessive tensile strength; and the poor compatibility between the sealing material and the main waterproofing layer easily creates leakage channels at the joints. Utility Model Content

[0004] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a BIM-based basement drainage structure. It uses waterproof membrane to waterproof the connection between the side walls and the base plate, and collects rainwater through external drainage ditches. This prevents the waterproof membrane on the side walls from being constantly exposed to alternating wet and dry conditions, thus avoiding a decrease in its service life and waterproofing effectiveness.

[0005] To achieve the above objectives, this utility model provides a BIM-based basement drainage structure, including a basement floor and side walls, with a base plate at the bottom of the floor and side walls, and a waterproof membrane at the connection between the side walls and the base plate. The waterproof membrane extends to the side end of the substrate and the top of the side wall at both ends, with its bottom end extending to the edge of the substrate and its top end extending above the ground. The waterproof membrane has a drainage ditch around its outer side, and a water collection well is provided outside the drainage ditch. The bottom end of the drainage ditch is connected to the water collection well.

[0006] Furthermore, the waterproof membrane has a staggered joint at the connection between the substrate and the side wall, and an arc at the corner. A gap is reserved between the arc and the connection corner between the substrate and the side wall, and an arc-shaped elastic plate is provided between the gap. The waterproof membrane is tightly attached to the surface of the elastic plate. The substrate is provided with a first baffle, the side wall is provided with a second baffle, and the spring plate is located between the first baffle and the second baffle to provide a limit.

[0007] Furthermore, the edge of the substrate is beveled so that the waterproof membrane is inclined at the connection between the substrate and the side wall; A rubber block is provided between the connection angle of the elastic plate and the base plate and the side wall.

[0008] Furthermore, a connecting groove is provided on the side wall at the position corresponding to the end of the waterproof membrane, and the waterproof membrane is placed in the connecting groove. A pressure strip is provided in the connecting groove of the side wall, and the waterproof membrane is pressed into the connecting groove by the pressure strip. The connecting groove also has an upward-sloping extension groove, which is inclined upwards, and the end of the waterproof membrane is fixed in the extension groove.

[0009] Furthermore, the inner side of the pressure strip is provided with a first rib and a second rib. The first rib is a long strip-shaped protrusion, which is centrally located along the length of the pressure strip. The second rib is provided in multiples, arranged in a figure-eight shape on both sides of the first rib. The pressure strip presses the waterproof membrane tightly against the inner wall of the connecting groove through the first and second ribs.

[0010] Furthermore, the rounded corners of the waterproof membrane are filled with a filler layer, which is a lightweight cement filler. The drainage ditch is located at the top of the filling layer, with its top opening at the ground level and inclined guide plates on both sides of the opening. The bottom of the drainage ditch is inclined toward the water collection well, and a water inlet pipe is provided on the side closest to the water collection well, through which the water inlet pipe is connected to the water collection well.

[0011] Furthermore, the bottom end of the guide plate of the drainage ditch is provided with a horizontal suspension platform, and the top end of the drainage ditch is provided with a cover plate, which is located between the inclined guide plates on both sides of the top end of the drainage ditch.

[0012] Furthermore, the cover plate includes a bottom drain plate and an arc-shaped drain plate.

[0013] Furthermore, the bottom drain plate includes a recessed portion in the middle, a suspension portion on both sides of the recessed portion, and a limiting portion on one side of the suspension portion; The concave portion is narrower than the drainage ditch, and its bottom is a flat plate with multiple regularly arranged circular filter holes forming a filter hole array. The suspension portion is connected to the concave portion by an inclined plate and is mounted on a suspension platform. The limiting portion is inclined and fits against the surface of the guide plate.

[0014] Furthermore, the arc-shaped filter plate has an arc-shaped cross-section and is inverted between the two limiting parts of the bottom filter plate to achieve lateral limiting of the arc-shaped filter plate. The surface of the arc-shaped filter plate is provided with multiple regularly arranged strip-shaped water filter grooves to form a water filter groove array.

[0015] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects: 1. The basement drainage structure of this utility model provides waterproofing at the connection between the side wall and the base plate through waterproof membrane, and collects rainwater on rainy days through the external drainage ditch, so as to avoid the waterproof membrane on the side wall being in a state of alternating dry and wet for a long time, which would affect the service life of the waterproof membrane and prevent its waterproof effect from weakening.

[0016] 2. The basement drainage structure of this utility model uses the elasticity and curvature of the spring plate to fix the waterproof membrane at right angles at corners, which is optimized into a rounded corner elastic connection. This avoids damage or hidden damage to the waterproof membrane due to excessive bending, thus ensuring the waterproof performance of the waterproof membrane.

[0017] 3. In the basement drainage structure of this utility model, when it rains, rainwater flows along the guide plate to the cover plate. Because the arc-shaped drain plate has a smooth upper surface, debris such as leaves and paper scraps in the rainwater are washed into the recessed areas formed between the sides of the arc-shaped drain plate and the bottom drain plate, preventing blockage of the filter channels on the arc-shaped drain plate, thus completing the initial screening of the rainwater. Furthermore, the debris is collected on both sides of the arc-shaped drain plate, and subsequent cleaning only requires shoveling it up with a tool, reducing the burden of subsequent debris removal. The rainwater may still contain smaller debris after the initial screening, which falls onto the bottom drain plate and undergoes fine filtration through the filter holes on the bottom drain plate. Subsequently, the arc-shaped drain plate can be periodically opened to clean the filtered impurities on the bottom drain plate.

[0018] 4. The basement drainage structure of this utility model uses two-stage filtration to prevent impurities from entering the water collection well, which would cause bacteria and viruses to grow and emit odors that affect environmental hygiene if soaked for a long time. In addition, the impurities after the two-stage filtration can be quickly cleaned up and are not prone to clogging. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figure 1-3 As shown, this utility model embodiment provides a BIM-based basement drainage structure, including a basement floor 3 and side walls 4. A base plate 2 is provided at the bottom of the floor 3 and side walls 4. A waterproof membrane 5 is provided at the connection between the side walls 4 and the base plate 2. The two ends of the waterproof membrane 5 extend towards the side end of the base plate 2 and the top of the side wall 4, respectively, with the bottom end extending to the edge of the base plate 2 and the top end extending above the ground. A drainage ditch 10 is provided around the outside of the waterproof membrane 5, and a collection well 12 is also provided outside the drainage ditch 10, with the bottom end of the drainage ditch 10 connected to the collection well 12. The waterproof membrane 5 provides waterproofing at the connection between the side walls 4 and the base plate 2, and the drainage ditch 10 collects rainwater, preventing the waterproof membrane 5 on the side walls 4 from being constantly exposed to alternating wet and dry conditions, thus avoiding a decrease in its service life and waterproofing effect.

[0023] The waterproof membrane 5 has a staggered joint at the connection between the substrate 2 and the side wall 4, and an arc at the corner. A gap is reserved between the arc and the connection angle between the substrate 2 and the side wall 4, and an arc-shaped elastic plate 6 is provided between the gaps. The waterproof membrane 5 is tightly attached to the surface of the elastic plate 6. A first baffle 201 is provided on the substrate 2, and a second baffle 401 is provided on the side wall 4. The elastic plate 6 is located between the first baffle 201 and the second baffle 401 to provide a limit. Through the elasticity and curvature of the elastic plate 6, the right-angle fixed connection of the waterproof membrane 5 at the corner is optimized into a rounded corner elastic connection, avoiding damage or hidden scratches caused by excessive bending of the waterproof membrane 5, and ensuring the waterproof performance of the waterproof membrane 5.

[0024] The edge of the substrate 2 is set as a slope so that the waterproof membrane 5 is inclined at the connection between the substrate 2 and the side wall 4, so that the water on the waterproof membrane 5 flows away along the slope towards the far end of the edge of the substrate 2, avoiding water accumulation at the corner of the waterproof membrane 5.

[0025] A rubber block 7 is provided between the connection angle of the elastic plate 6 and the base plate 2 and the side wall 4. The rubber block 7 is made of elastic rubber to fill the gap between the elastic plate 6, the base plate 2 and the side wall 4, and to provide support for the elastic plate 6.

[0026] The rounded corners of the waterproof membrane 5 are also filled with a filling layer 8, which is a lightweight cement filler, so as to compact the waterproof membrane 5 at its rounded corners.

[0027] A connecting groove is formed on the side wall 4 at a position corresponding to the end of the waterproof membrane 5. The waterproof membrane 5 is placed in the connecting groove, and a pressure strip 9 is provided in the connecting groove of the side wall 4 to press the waterproof membrane 5 tightly into the connecting groove. An upward-sloping extension groove is also provided in the connecting groove, and the end of the waterproof membrane 5 is fixed in the extension groove. The inclined extension and fixation of the top end of the waterproof membrane 5 prevents rainwater from entering the side wall 4 along the gaps, achieving a better waterproof effect.

[0028] like Figure 4 As shown, the inner side of the pressure strip 9 is provided with a first protruding rib 901 and a second protruding rib 902. The first protruding rib 901 is an elongated protrusion, which is centrally located along the length of the pressure strip 9. Multiple second protruding ribs 902 are provided, arranged in a V-shape on both sides of the first protruding rib 901. The pressure strip 9 presses the waterproof membrane 5 tightly against the inner wall of the connecting groove through the first protruding ribs 901 and the second protruding ribs 902, so as to make it tightly connected with the side wall 4 and achieve a better waterproof effect.

[0029] The drainage ditch 10 is located at the top of the filling layer 8, with its top opening at ground level. Inclined guide plates are provided on both sides of the opening to allow rainwater to flow smoothly into the drainage ditch 10. The bottom of the drainage ditch 10 slopes towards the collection well 12, and a water inlet pipe is provided on the side closest to the collection well 12, connecting the ditch to the collection well 12. Rainwater entering the drainage ditch 10 flows into the collection well 12 for storage through the water inlet pipe.

[0030] A drainage pump 13 is installed on the ground above the collection well 12. The input end of the drainage pump 13 is connected to the collection well 12 via a drainage pipe, which is connected to the bottom of the collection well 12. After the rain stops, the drainage pump 13 pumps the rainwater stored in the collection well 12 to the ground. It can be understood that the rainwater collected in the collection well 12 during rainy weather can be stored and pumped out by the drainage pump 13 to irrigate green plants during dry weather.

[0031] like Figure 5 As shown, the bottom of the guide plate of the drainage ditch 10 is provided with a horizontal suspension platform, and the top of the drainage ditch 10 is provided with a cover plate 11, which is located between the inclined guide plates on both sides of the top of the drainage ditch 10. The cover plate 11 includes a bottom drain plate 111 and an arc-shaped drain plate 112. The bottom drain plate 111 includes a concave portion in the middle, a suspension portion on both sides of the concave portion, and a limiting portion on one side of the suspension portion. The width of the concave portion is smaller than the width of the drainage ditch 10, and its bottom is a flat plate structure with multiple regularly arranged circular filter holes forming a filter hole array. The suspension portion is connected to the concave portion by an inclined plate and is located on the suspension platform. The limiting portion is inclined and fits against the surface of the guide plate. The arc-shaped filter plate 112 has an arc-shaped cross section and is inverted between the two limiting parts of the bottom filter plate 111 to achieve lateral limiting of the arc-shaped filter plate 112. The surface of the arc-shaped filter plate 112 is provided with multiple regularly arranged strip-shaped water filter grooves to form a water filter groove array.

[0032] Understandably, when it rains, rainwater flows along the guide plate onto the cover plate 11. Because the arc-shaped drain plate 112 has an arc-shaped cross-section and a smooth upper surface, debris such as leaves and paper scraps in the rainwater are washed into the recessed areas formed between the sides of the arc-shaped drain plate 112 and the bottom drain plate 111, preventing blockage of the filter channels on the arc-shaped drain plate 112 and thus completing the initial screening of the rainwater. Furthermore, the debris is collected on both sides of the arc-shaped drain plate 112, and subsequent cleaning can be done simply by shoveling it up with a tool, reducing the burden of subsequent debris removal. After the initial screening, the rainwater may still contain smaller debris, which falls onto the bottom drain plate 111. The rainwater undergoes fine filtration through the filter holes on the bottom drain plate 111. Subsequently, the arc-shaped drain plate 112 can be periodically opened to clean the filtered impurities on the bottom drain plate 111. The two-stage filtration system prevents impurities from entering the water collection well 12, which would otherwise cause bacteria and viruses to grow and emit foul odors, affecting environmental hygiene. Furthermore, the impurities filtered through both stages can be quickly cleaned up, preventing clogging.

[0033] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
