Description

Technical Field

[0001] This utility model mainly relates to the field of basement structure technology, specifically a basement structure based on BIM technology. Background Technology

[0002] With the continuous development of the construction industry, the application of BIM technology is becoming more and more widespread. It combines architecture with computer-aided design, models the building before construction, and simulates feasible building plans by combining various building data. At the same time, it has a certain guiding role in the construction process.

[0003] Currently, basements simulated using BIM technology typically rely on laying waterproofing materials to prevent water seepage. However, using only waterproofing materials is insufficient and fails to fully utilize the visualization capabilities of BIM technology to monitor seepage at various locations within the basement, hindering subsequent management and repairs. Utility Model Content

[0004] The purpose of this utility model is to provide a basement structure based on BIM technology to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a basement structure based on BIM technology, comprising a bottom slab, a top slab, and side wall panels, wherein the side wall panels are located between the bottom slab and the top slab; The base plate includes a gravel blind drain layer, a concrete support layer and a surface decoration layer stacked from bottom to top. A perforated drainage pipe connected to an external pipeline is embedded in the gravel blind drain layer. Multiple vertical drainage channels are provided on the outer side of the side wall panel. A water guide pipe is connected between the vertical drainage channels and the gravel blind drain layer. The top slab is a segmented cast-in-place component. Humidity sensors are pre-embedded on both sides of the construction joint. The data from the humidity sensors is transmitted to the BIM operation and maintenance platform. Multiple inverted ribs are installed on the top slab, and a transverse drainage channel connected to the external pipeline is formed between adjacent inverted ribs.

[0006] Preferably, the side wall panel includes an inner concrete layer, a waterproof core layer, and an outer concrete layer stacked sequentially from the inside to the outside, and the vertical drainage channel is located on the outer concrete layer.

[0007] Furthermore, the inner and outer concrete layers are integrally cast with tenons, and the bottom and top plates have mortises pre-reserved on their inward-facing sides to fit the tenons. The connection between the tenons and the mortises is filled with butyl rubber sealant.

[0008] Preferably, the construction joint of the top slab is filled with a composite water-stop component, which is a triple-layer structure with a steel plate water-stop strip at the center and water-swellable rubber strips on both sides.

[0009] Furthermore, the base plate and side wall plate are also segmented cast-in-place components, and composite water-stopping components are installed in their construction joints. Humidity sensors are also pre-embedded on both sides of the construction joints.

[0010] Preferably, the top of the top plate slopes from the center to both sides along the direction of the transverse drainage channel to form a drainage slope.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model constructs an active drainage system through the coordinated use of a crushed stone blind ditch layer, perforated drainage pipes, water guide pipes, vertical drainage channels, and horizontal drainage channels. This effectively guides groundwater and rainwater outwards, reducing the risk of water seepage. At the same time, the tenon and mortise sealing connection and composite water-stop components enhance the waterproof performance at the structural joints, improving moisture resistance from the source.

[0012] This invention enables dynamic and visual monitoring of basement water seepage by pre-embedding humidity sensors in construction joints and connecting them to a BIM operation and maintenance platform. This facilitates accurate location of potential leakage points and, combined with BIM model guidance, provides real-time data for subsequent maintenance and repair, thereby improving management efficiency.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1 to 5 As shown, a basement structure based on BIM technology includes a bottom slab 1, a top slab 2, and side wall panels 3, with the side wall panels 3 located between the bottom slab 1 and the top slab 2. The base plate 1 includes a gravel blind drain layer 11, a concrete support layer 12 and a surface decoration layer 13 stacked from bottom to top. A perforated drainage pipe 14 connected to an external pipeline is embedded in the gravel blind drain layer 11. Multiple vertical drainage channels 5 are provided on the outer side of the side wall plate 3. A water guide pipe 15 connects the vertical drainage channels 5 and the gravel blind drain layer 11. The top slab 2 is a segmented cast-in-place component. Humidity sensors 9 are pre-embedded on both sides of the construction joint. The data of the humidity sensors 9 is transmitted to the BIM operation and maintenance platform. Multiple inverted ribs 4 are set on the top slab 2. A transverse drainage channel connected to the external pipeline is formed between adjacent inverted ribs 4.

[0019] The humidity sensor 9 in the top plate 2 is embedded in the backwater position, that is, the bottom of the top plate 2, so as to effectively monitor the water seeping into the cement from the outside to the inside and ensure the accuracy of the monitoring.

[0020] The surface decorative layer 13 is made of rubber, which has a large load-bearing capacity, is non-slip and safe, and can further improve the waterproof performance of the base plate 1 surface.

[0021] The side wall panel 3 includes an inner concrete layer 31, a waterproof core layer 32, and an outer concrete layer 33 stacked sequentially from the inside to the outside. The vertical drainage channel 5 is located on the outer concrete layer 33. A hydrophobic layer is provided on the surface of the vertical drainage channel 5. The spacing between adjacent vertical drainage channels 5 is the same, which uniformly guides the water on the surface of the outer concrete layer 33 to the position of the water guide pipe 15.

[0022] The inner concrete layer 31 and the outer concrete layer 33 are integrally cast with a tenon 6. The bottom plate 1 and the top plate 2 have a tenon groove 7 that fits the tenon 6 on their inner side. The connection between the tenon 6 and the tenon groove 7 is filled with butyl rubber sealant, thereby sealing the joint between the tenon 6 and the tenon groove 7 and improving the waterproof performance.

[0023] The construction joint of the top slab 2 is filled with a composite water-stop component 8. The composite water-stop component 8 has a triple-layer structure, with a steel plate water-stop strip 81 at the center and water-swellable rubber strips 82 on both sides, thereby sealing the construction joint and improving the waterproof performance.

[0024] The base plate 1 and the side wall plate 3 are also segmented cast-in-place components. Composite water-stopping components 8 are also installed in their construction joints, and humidity sensors 9 are also pre-embedded on both sides of the construction joints to monitor the water-permeable points of each plate.

[0025] Depending on construction needs, other structural joints (such as expansion joints) can also be set, and the remaining structural joints are also filled with composite water-stopping components.

[0026] The top of the top plate 2 slopes from the center to both sides along the direction of the transverse drainage channel to form a drainage slope, and the angle of the drainage slope is not less than 2°.

[0027] The implementation principle of this application embodiment is as follows: In the use of this structure, when water falls to the top plate 2, it flows along the drainage slope into the two ends of the transverse drainage channel between the inverted rib beams 4 and is directly discharged. If water seeps into the construction joint, the water-swellable rubber strip 82 of the composite water-stop component 8 expands to seal the micro gaps, and the steel plate water-stop strip 81 blocks longitudinal penetration. When water seeps through the composite water-stop component 8 at some points, the humidity sensor 9 embedded on the back side of the construction joint monitors the abnormality in real time and uploads the data to the BIM platform for alarm. When water adheres to the outer concrete layer 33 of the side wall panel 3, it is guided by the vertical drainage channel 5 and introduced into the gravel blind drain layer 11 of the bottom plate 1 through the water pipe 15. If water seeps into the gap between the inner concrete layer 31 and the outer concrete layer 33, the mechanical interlocking of the tenon 6 and the mortise 7 and the butyl rubber sealant block the lateral migration. The waterproof core layer 32 provides secondary barrier. Water seepage in the construction joint is sealed by the composite water-stop component 8, and the humidity sensor 9 triggers monitoring simultaneously. When groundwater surges to the bottom slab 1, the gravel blind drain layer 11 quickly guides the water to the perforated drainage pipe 14 for discharge. The residual water is blocked by the concrete support layer 12, and the rubber surface decorative layer 13 prevents internal dampness. The side wall seepage water entering through the water pipe 15 is simultaneously absorbed by the gravel blind drain layer 11 to avoid water accumulation.

[0028] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from its essential characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
