Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a foundation pile cap for preventing water seepage at the joint of pile heads. Background Art

[0002] A foundation pile cap refers to a reinforced concrete platform that is set at the top of a foundation pile to bear and distribute the load transmitted by the pier shaft. During the construction process, usually the pile head is built first, and then the bottom cushion and the foundation pile cap are poured, and the pile head is embedded into the foundation pile cap. Both the pile cap and the bottom cushion are poured after the pile head is formed, so there will be a construction joint between the pile head and the foundation pile cap, which causes groundwater to penetrate into the surface of the basement floor through the construction joint between the pile head and the foundation pile cap, affecting the construction quality. And over time, there will be ponding on the surface of the basement floor. When a vehicle passes by, the wheels will slip, and accidents are likely to occur.

[0003] Chinese Patent with Publication No. CN218521833U proposes a drainage device for a tower crane foundation pile cap, which discharges the water on the upper surface of the foundation pile cap by setting structures such as a drainage frame, a water collecting bucket and a drain pipe in the foundation pile cap. However, this device can only discharge the ponding on the upper surface of the foundation pile cap, and cannot handle the water seeping in from the connection between the pile head and the foundation pile cap. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to propose a foundation pile cap for preventing water seepage at the joint of pile heads to solve the above problems.

If the accumulated water in the installation groove fails to be discharged smoothly and there is too much accumulated water in the installation groove, then under the action of buoyancy, the floating plate rises, driving the push rod to rise. Until the push rod pushes the triggering mechanism, a closed circuit is formed among the triggering mechanism, the battery, and the warning light, and the warning light lights up to remind relevant personnel to solve the accumulated water problem in time. Therefore, this device effectively solves the problem of water seepage at the pile head joint, can timely discharge the accumulated water, prevent it from penetrating to the surface of the basement floor slab and causing water accumulation on the basement floor slab, thereby preventing the problem of wheel slippage when vehicles pass by.

[0018] As Figures 1 to 4 shown, a foundation cap for preventing water seepage at the joint of the pile head 1 proposed by the present invention is composed of a mounting seat 3, a drain pipe 5, a sliding rod, a floating plate 8, a push rod 9, a triggering mechanism, a warning light 10, a battery 11, etc. The mounting seat 3 is of a cylindrical structure and is installed on the bottom cushion layer 2. An installation groove 4 is provided in the mounting seat 3. The installation groove 4 is of a cylindrical structure and is arranged at the lower part of the mounting seat 3. The axis of the installation groove 4 and the axis of the mounting seat 3 are on the same straight line. The pile head 1 extends into the installation groove 4 from above the mounting seat 3, and the pile head 1 is fixedly connected to the mounting seat 3. A drain pipe 5 is arranged in the mounting seat 3. One end of the drain pipe 5 communicates with the installation groove 4, and the other end of the drain pipe 5 extends out of the mounting seat 3. The drain pipe 5 is connected to the bottom of the installation groove 4 and is used to drain the accumulated water flowing into the installation groove 4.

[0019] The sliding rod is composed of a main rod 6 and a limiting plate 7. One end of the main rod 6 is connected to the top surface of the installation groove 4, and the main rod 6 is perpendicular to the lower surface of the mounting seat 3. A floating plate 8 is slidably connected to the main rod 6, and a push rod 9 perpendicular to the floating plate 8 is connected to the upper surface of the floating plate 8. Preferably, the main rod 6 is of a cuboid structure to prevent the floating plate 8 from rotating relative to the main rod 6. The other end of the main rod 6 is connected to a limiting plate 7 to prevent the floating plate 8 from falling off.

[0020] The triggering mechanism is composed of a telescopic rod 12, a push plate 13, a first electrode pin 14, and a second electrode pin 15. An activity groove is provided at a position on the top surface of the installation groove 4 opposite to the top end of the push rod 9, and one end of the telescopic rod 12 is connected to the top surface of the activity groove. The other end of the telescopic rod 12 is connected to the push plate 13. The push plate 13 is arranged at the port of the activity groove and is parallel to the top surface of the installation groove 4. The telescopic rod 12 plays a role in connecting and guiding the push plate 13, and the number of telescopic rods 12 is greater than or equal to two. A first electrode pin 14 is connected to the top surface of the activity groove, and a second electrode pin 15 is connected to a position on the upper surface of the push plate 13 opposite to the first electrode pin 14. A warning light 10 is connected to the outer wall of the mounting seat 3. The first electrode pin 14 is connected to the warning light 10 through an electric wire, the warning light 10 is connected to the battery 11 through an electric wire, and the battery 11 is connected to the second electrode pin 15 through an electric wire. Thus, after the first electrode pin 14 contacts the second electrode pin 15, a closed circuit is formed, and the warning light 10 lights up.

[0021] A placement groove is provided on the upper surface of the mounting seat 3, and the battery 11 is placed in the placement groove. A cover plate 18 is provided at the port of the placement groove, and a limiting block is connected to the side of the cover plate 18. The limiting block is made of rubber. A limiting groove for cooperating with the limiting block is provided on the inner wall of the placement groove, so that the cover plate 18 is connected to the limiting groove to protect the battery 11. An extraction groove is provided on the cover plate 18, and a handle 19 is rotatably connected to the extraction groove. The cover plate 18 is opened by pulling the handle 19.

[0022] An annular sealing groove is provided at the outer edge of the lower surface of the mounting seat 3, and an annular sealing plate 16 is arranged in the annular sealing groove. A plurality of spring telescopic rods 1712 are evenly distributed in the annular sealing groove. One end of the spring telescopic rod 1712 is connected to the top surface of the annular sealing groove, and the other end of the spring telescopic rod 1712 is connected to the annular sealing plate 16. By providing the annular sealing plate 16, it is possible to effectively reduce the water flowing in from the edge where the mounting seat 3 is in contact with the bottom cushion 2.

[0023] Working process: After water enters from the construction joint between the pile head 1 and the mounting seat 3, it flows into the installation groove 4, and the accumulated water in the installation groove 4 is discharged from the drain pipe 5. If problems such as blockage occur in the drain pipe 5, causing the water in the installation groove 4 to not be discharged in time, the infiltrated water will remain in the installation groove 4. As the water level in the installation groove 4 rises, the floating plate 8 moves upward, driving the push rod 9 to move upward. Until the accumulated water in the installation groove 4 reaches a certain amount, the push rod 9 pushes the push plate 13, and the first electrode pin 14 contacts the second electrode pin 15, forming a closed circuit, and the warning light 10 lights up. At this time, the staff can discover it in time and deal with the accumulated water in the installation groove 4. Therefore, the present invention effectively solves the problem of water seepage at the joint of the pile head 1, can discharge the accumulated water in time, and avoids infiltrating to the surface of the basement floor to cause basement floor water accumulation, thereby preventing the problem of wheel slippage when vehicles pass by.
