Description

Technical Field

[0001] This invention belongs to the field of building waterproofing technology, specifically a waterproofing and leakage prevention structure for post-cast strips of basement floor slabs. Background Technology

[0002] The post-cast strip of the basement floor slab is a temporary construction joint set in the ultra-long or large-area basement structure. It is located in the concrete of the floor slab and is mainly used to solve the tensile stress caused by factors such as temperature changes and drying shrinkage in the concrete, prevent through cracks in the floor slab, and at the same time take into account the adjustment of differential settlement. It is a key structural measure to ensure the integrity, waterproofing and durability of the basement structure.

[0003] A patent with publication number CN115110583B discloses a waterproofing structure for post-cast strips in basement slabs. The key technical points are: it includes a base slab, a post-cast strip, a cushion layer, a thickened cushion layer under the post-cast strip, and a waterproof membrane. The post-cast strip connects the two sides of the base slab. The waterproof membrane is laid under the base slab and the post-cast strip. The cushion layer is located below the waterproof membrane. The thickened cushion layer under the post-cast strip is located below the cushion layer. It also includes a water-stop block, one end of which is located inside the base slab, and the other end is located inside the post-cast strip. The water-stop block has a cavity, and its bottom has a water-stop hole communicating with the cavity. A water-stop strip is inserted into the water-stop hole, and the water-stop strip simultaneously abuts against the base slab and the post-cast strip. The top of the water-stop block has several water-guiding holes communicating with the cavity. This application has the following effect: it can improve the waterproofing effect at the joint between the base slab and the post-cast strip.

[0004] However, the above technologies often have the following drawbacks: when the groundwater level fluctuates and the amount of water accumulation changes significantly, relying solely on the water diversion hole is relatively limited in its effectiveness and may lead to water blockage. Water blockage can cause rainwater leakage and makes it difficult to adjust the tilt angle of the diversion mechanism according to the actual rainfall, thereby adjusting the water diversion speed and reducing blockage.

[0005] Therefore, the present invention provides a waterproof and leak-proof structure for the post-cast strip of the basement floor slab. Summary of the Invention

[0015] The beneficial effects of this invention are as follows:

[0016] 1.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Reference Figure 1 - Figure 6 This invention provides two technical solutions: Example 1:

[0029] A waterproof and leak-proof structure for post-cast strip of basement floor includes a surface layer 1. A cover plate 2 is overlapped on the upper surface of the surface layer 1. Corrugated water diversion channels 3 and straight water diversion channels 4 are spaced apart on the upper surface of the cover plate 2. A multi-position lifting mechanism is provided inside the corrugated water diversion channels 3 and the straight water diversion channels 4. A sensor chip 5 is embedded in the inner sidewall of the corrugated water diversion channels 3 and the straight water diversion channels 4. A waterproof plate A 6 is fixedly connected inside the surface layer 1. A reinforcement mechanism is fixedly connected to the bottom of the waterproof plate A 6.

[0030] The multi-station lifting mechanism includes a frame 7, the surface of which is fixedly connected to the side of the cover plate 2. A miniature electric push rod 8 is fixedly connected to the side wall of the frame 7. One end of the miniature electric push rod 8 is fixedly connected to a pushing rod 9. Connecting blocks 10 are fixedly connected at intervals in the middle of the pushing rod 9. A connecting rod 11 is rotatably connected to the outer surface of the connecting block 10 via a rotating shaft A. One end of the connecting rod 11 is rotatably connected to a lifting rod 12 via a rotating shaft B. A connecting plate 13 is rotatably connected to the middle of the connecting rod 11 via a rotating shaft C. The top end of the connecting plate 13 is fixedly connected to the bottom of the frame 7. The lifting rod... One end of 12 is fixedly connected to a lifting plate 14. During rainfall or water accumulation, the tilt height of the diversion plate 18 is adjusted using a multi-position lifting mechanism according to the actual situation, so that the diversion path is always in the optimal flow state, improving drainage efficiency and diversion capacity, guiding water flow through weak points and potential water collection points of the waterproof layer, reducing the accumulation area of ​​leakage, and improving the overall waterproof continuity. In addition, when the rainfall increases, the effective drainage slope is increased by raising the angle of the diversion plate 18, reducing the impact of local water pressure on the bottom plate 27 and the waterproof interface, and reducing the risk of local leakage caused by water pressure peaks. Example 2:

[0031] An A regulating plate 15 is fixedly connected to one side of the lifting plate 14. A B regulating plate 17 is rotatably connected to the middle of the A regulating plate 15 via a rotating rod 16. A diversion plate 18 is fixedly connected to one end of the B regulating plate 17. A waterproof pad 19 is fixedly connected to the upper surface of the diversion plate 18. The fixed connection of the diversion plate 18 forms a controllable drainage channel in a specific area. Combined with the waterproof pad 19, the coupling optimization of diversion and waterproofing can be achieved, reducing the local impact of water pressure on the waterproof interface. The waterproof pad 19 provides a nearly continuous watertight surface, reducing the penetration path of water along the interface and reducing the chance of leakage.

[0032] The reinforcement mechanism includes a cover plate 20, the upper surface of which is fixedly connected to the bottom of waterproof membrane 6. A reinforcing steel bar 21 is fixedly connected to the bottom of the cover plate 20. The reinforcing steel bar 21 is arranged in a diamond shape at the bottom of the cover plate 20. A honeycomb cylinder 22 is fixedly connected to the central cavity of the reinforcing steel bar 21. A bearing plate 23 is fixedly connected to the bottom of the reinforcing steel bar 21. By reinforcing the post-pouring strip and its interface, the stress concentration of the waterproof layer caused by deformation is reduced, the adhesion and continuity of the waterproof layer and the structural interface are improved, the probability of leakage is reduced, and the points distributed in the crack-prone areas or weak zones can achieve local stress dispersion, alleviate stress concentration, and improve local and overall stability.

[0033] A monitoring sensor 24 is fixedly installed on the side of the cover plate 2. The monitoring sensor 24 is electrically connected to the sensing chip 5. The combined use of the sensing chip 5 and the monitoring sensor 24 can continuously collect information such as rainfall, water depth, and seepage rate, forming a real-time data stream to support rapid decision-making and send signals to the multi-station lifting mechanism to adjust the drainage flow in real time.

[0034] Both sides of the bearing plate 23 are fixedly connected to the ramp plate 25. The inner side wall of the ramp plate 25 is snapped with the trapezoidal plate 26. The inner side wall of the trapezoidal plate 26 is fixedly connected with the bottom plate 27. The ramp plate 25 and the surface layer 1 are snapped together by the cover plate 20 in a mortise and tenon manner. The mortise and tenon connection is a high-rigidity mechanical connection, which improves the rigidity of the boundary area, reduces the risk of local deformation and cracks, improves the waterproof effect, and reduces leakage.

[0035] Both sides of the surface layer 1 are fixedly connected to waterproof membrane 28. The surface of waterproof membrane 28 is coated with waterproof coating. As an additional waterproof barrier, the side waterproof membrane 28 can share the water pressure when the groundwater level fluctuates or rainwater seeps in, reduce the stress concentration on the internal waterproof layer, form a continuous waterproof barrier, reduce the path of water seepage from the side wall into the basement, and improve the overall waterproof level.

[0036] A drainage plate 29 is fixedly installed on the upper surface of the cover plate 2. The surface of the drainage plate 29 has several drainage grooves. As an additional waterproof barrier, the drainage plate 29 can prevent surface water from directly entering the lower structure, reducing the number and length of seepage paths. The drainage grooves can guide surface water to collect along a specific path to the drainage point, preventing water from accumulating on the surface of the cover plate 2 and forming a water accumulation area, thus reducing the pressure of seepage on the base layer.

[0037] Working principle: When precipitation or water accumulation occurs, water flows within the corrugated water inlet channel 3 and the straight water inlet channel 4. Together, these two channels form multiple drainage channels, automatically switching to another channel when one is blocked, improving overall drainage capacity and system redundancy. The corrugated structure promotes water flow dispersion and guidance, reducing scouring and localized wear caused by high-speed flow, while also helping to mitigate water flow impact. When rapid drainage and a stable drainage path are required, the straight channel provides a low-resistance, continuous guiding surface, improving drainage efficiency. The alternating arrangement of the two channel types allows water pressure to be distributed across different areas, reducing single-point water pressure peaks and minimizing localized stress concentration on the waterproofing layer and interface. By homogenizing drainage speed and water head distribution, leakage along the horizontal direction is reduced. The driving force extends, and then the flow rate is sensed by the sensing chip 5 in the corrugated water channel 3 and the straight water channel 4. The flow rate is monitored in real time by the monitoring sensor 24 and transmitted to the multi-station lifting mechanism. The micro electric push rod 8 is activated. When the micro electric push rod 8 extends and retracts, it drives the push rod 9 to move within the frame 7. When the push rod 9 moves, the connecting block 10 on its surface drives the connecting rod 11 to rotate. The connecting rod 11 rotates on the connecting plate 13 through the C-axis in the middle. When it rotates, the other end moves up and down. When it moves up and down, it drives the lifting rod 12 to rise and fall. When the lifting rod 12 rises and falls, it drives the A adjustment plate 15 to rotate through the lifting plate 14. The A adjustment plate 15 rotates on the B adjustment plate 17 through the rotating rod 16, so that the tilt angle of the A adjustment plate 15 and the B adjustment plate 17 is changed. When the A-adjustment plate 15 is adjusted, it moves the surface waterproof pad 19 together with it. Water flows over the waterproof pad 19. By changing the tilt angle, the flow rate of the water can be adjusted, ensuring that the drainage path is always in the optimal flow state, improving drainage efficiency and drainage capacity. This guides the water flow through weak points and potential water collection points in the impermeable layer, reducing areas of leakage accumulation and improving the overall waterproof continuity. In addition, when rainfall increases, the effective drainage slope is increased by raising the angle of the diversion plate 18, reducing the impact of local water pressure on the bottom plate 27 and the waterproof interface, and reducing the risk of local leakage caused by water pressure peaks. Subsequently, a B-waterproof plate 28 is installed on the side of the surface layer 1. The side B-waterproof plate 28 acts as an additional waterproof barrier, which can share the water pressure when the groundwater level fluctuates or rainwater seeps in, mitigating the impact. Stress concentration in the internal waterproofing layer creates a continuous waterproof barrier, reducing the path for water seepage from the side walls into the basement and improving the overall waterproofing level. During construction, a base slab 27 and a trapezoidal slab 26 are built inside the surface layer 1. The trapezoidal slab 26 enhances load-bearing capacity. A sloping slab 25 is added outside the trapezoidal slab 26. The cover plate 20 is then attached to the surface layer 1 using mortise and tenon joints. This high-rigidity mechanical connection increases the rigidity of the boundary area, reduces the risk of local deformation and cracking, improves waterproofing, and reduces leakage. Reinforcing steel bars 21 are added above the cover plate 20, arranged in a staggered diamond pattern. Honeycomb cylinders 22 are added in the gaps, forming an additional load-bearing mesh above the cover plate 20.It can better distribute vertical and horizontal loads, improving the overall bending, shear, and lateral displacement resistance. The staggered diamond arrangement helps to increase grid stiffness, reduce excessive bending and local deformation in the mid-span and edge areas, thereby reducing the probability of crack initiation. The addition of honeycomb cylinders 22 can provide near-equivalent local stiffening support in the void areas, improving damping and resistance to dynamic loads. Honeycomb cylinders 22 can form local sealing and drainage buffer zones in the voids, reducing moisture retention in the voids and improving durability.
