Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a basement floor anti-leakage and cracking structure. Background Art

[0002] A basement is a room where the ground is lower than the outdoor ground level by more than half of the room's net height. Multi-story and high-rise buildings require a deeper foundation. To take advantage of this height, a basement is built under the ground floor of the building, which can increase the usable area and save the backfill soil in the center of the house. At present, due to the high groundwater level in some areas, the strong water pressure can easily cause cracks and leakage in the basement floor. This is a quality problem that often occurs during the delivery and use of construction projects, especially in areas with abundant groundwater. The leakage rate in 28 cities in my country reached 57.51%. In some cities such as Chongqing and Wuxi, the leakage rate of underground buildings was 100%.

[0003] The commonly used treatment solutions for basement floor leakage and cracking are: drilling, installing needles, and pressure-injecting chemical materials. However, the above solutions have a long treatment cycle and are repetitive, and it is difficult to completely "cure" the problem. In addition, the treatment effect can only be tested after the base is completely dry, which is difficult to achieve due to the complex on-site conditions during the construction process.

[0032] The auxiliary drainage assembly includes a slide rod 14, the upper end of which is fixedly connected to the middle of the lower end of the inverted eight-shaped water collecting strip 10, and the lower end of which is slidably connected to the V-shaped water collecting strip 12 in the up and down directions. A drainage hole 15 is opened in the middle of the slide rod 14.

[0033] A first slope 16 is arranged between the left and right ends of the inner side of the inverted eight-shaped water-collecting strip 10 and the inner wall of the basement raft 1, a second slope 17 is fixedly connected between the inverted eight-shaped water-collecting strip 10 on the left front side and the inner front side of the bracket frame 9, and a second slope 17 is fixedly connected between the inverted eight-shaped water-collecting strip 10 on the rear side and the inner rear side of the bracket frame 9; during operation, through the setting of the first slope 16, the length of the lower port of the inverted eight-shaped water-collecting strip 10 can be made smaller than the length of the upper port of the V-shaped water-collecting strip 12, so that all the water in the inverted eight-shaped water-collecting strip 10 can flow into the V-shaped water-collecting strip 12; through the setting of the second slope 17, the water on the front and rear sides of the bracket frame 9 can flow into the inverted eight-shaped water-collecting strip 10.

[0037] The inverted figure-eight-shaped water collecting strip 10 is made of iron. During operation, the inverted figure-eight-shaped water collecting strip 10 is made of iron, so that the inverted figure-eight-shaped water collecting strip 10 can have a good condensation effect.

[0038] Working principle:

[0039] When the structure is in use, after the groundwater penetrates through the basement raft 1 to the surface of the basement raft 1, the water will flow into it along the drain plate 7; when the groundwater penetrates through the basement structure wall 2 and pours the upper surface of the floor 3, the water will first flow into the intercepting ditch 6, and then flow into the drainage ditch 4 through the drain plate 7; when the water flows into the drainage ditch 4, the floating block 13 will move upward under the buoyancy of the water, and the floating block 13 will push the sliding frame 11 upward through the connecting rod 19, and the sliding frame 11 will drive the V-shaped water collecting bar 12 and the limiting plate 18 to move upward. When the limiting plate 18 moves upward and touches the second slope 17, the height of the upper port of the V-shaped water collecting bar 12 just slightly exceeds the lower port of the inverted eight-shaped water collecting bar 10. After that, the water in the drainage ditch 4 forms moisture, and the moisture is easily condensed when it meets the iron inverted eight-shaped water collecting bar 10. The condensed water flows into the V-shaped water collecting bar 12 along the inclined wall of the inverted eight-shaped water collecting bar 10 until the V-shaped water collecting bar 12 is The water in the water strip 12 submerges the lower port of the inverted eight-shaped water-collecting strip 10, thereby forming a small-area water seal to prevent moisture in the drain ditch 4 from leaking out, while water from the outside can flow into the V-shaped water-collecting strip 12 through the inverted eight-shaped water-collecting strip 10, and then submerge the upper port of the V-shaped water-collecting strip 12 and flow into the drain ditch 4; when there is sewage in the drain ditch 4, the sliding frame 11 slides down to the bottom of the bracket frame 9 under the action of gravity, and the sliding frame 11 drives the V-shaped water-collecting strip 12 to move downward, causing the height of the upper port of the V-shaped water-collecting strip 12 to be lower than the lower port of the inverted eight-shaped water-collecting strip 10, and the upper end of the drainage hole 15 passes over the upper surface of the inner side of the V-shaped water-collecting strip 12, and the lower end of the drainage hole 15 is still located on the lower side of the V-shaped water-collecting strip 12, so that the water in the V-shaped water-collecting strip 12 flows out through the drainage hole 15, and the water spreads out in the drain ditch 4 and evaporates quickly, thereby keeping the drain ditch 4 and the basement outside the drain ditch 4 dry.

[0040] To sum up, the structure can transport the water that penetrates into the basement through the intercepting ditch 6 and the hydrophobic plate 7 to the drainage ditch 4, and flow into the water collection well on the basement raft 1 through the drainage ditch 4, so as to form a complete drainage system, prevent the formation of large-scale water accumulation on the basement surface, and at the same time reduce the pressure of the basement raft 1 on the groundwater, and prevent the basement raft 1 from cracking under the action of huge water pressure; when there is water in the drainage ditch 4, the device can form an area water seal at the upper end of the drainage ditch 4 through the moisture-proof cover mechanism, prevent the moisture in the drainage ditch 4 from leaking into the basement, thereby improving the dryness of the basement. If there is no infiltration in the basement for a long time, the moisture-proof cover mechanism will automatically release the water seal, so that the inside and outside of the drainage ditch 4 remain relatively dry.

[0041] The technical features disclosed above are not limited to the disclosed combinations with other features. Those skilled in the art may also make other combinations between the technical features according to the purpose of the utility model to achieve the purpose of the utility model.
