Description

Technical Field

[0001] This utility model relates to the technical field of foundation pit support and water-blocking devices, specifically to construction foundation pit support and water-blocking devices. Background Technology

[0002] During building construction, it is necessary to excavate a foundation pit. In order to ensure the safety of underground structure construction and the surrounding environment of the foundation pit, a foundation pit excavation support structure is often required to support the foundation pit.

[0003] A patent database discloses a water-blocking device for foundation pit support in building construction (authorization announcement number CN221545647U), which includes a first base block; two symmetrical first grooves are formed at the upper end of the first base block about the center of the upper end face of the first base block, and a first fixing plate is fixedly connected to the center of the upper end of the first base block. In use, because the first threaded column is adjustable, the distance between the second base block and the first base block can be easily adjusted, ultimately pressing the support plate against the side wall of the foundation pit. By placing the rainproof plate on the upper end of the support block, rainwater falling on the rainproof plate will flow along the slope of the rainproof plate into the water collection trough, and then flow out through the third internal threaded cylinder. The third internal threaded cylinder can be connected to an external pipe to guide the water to a rainwater well or sewage well on a municipal road, thus facilitating the support and drainage of the foundation pit, and is easy to use.

[0004] The aforementioned support and water-blocking device for foundation pits has a fixed length at both ends of the rainproof plate during use, while the distance between the two support plates below can be adjusted according to actual needs. Therefore, when the distance between the two support plates is different, it is necessary to replace it with a rainproof plate of a suitable length. The aforementioned rainproof plate does not have an adjustment structure, which limits its use, reduces its applicability, and makes it relatively impractical. Utility Model Content

In this example, the adjustable distance component 1 2 consists of a threaded column, an internal threaded cylinder, and a bottom block. The adjustable distance component 2 3 consists of a fixed body, a threaded column, and a U-shaped block. The lengths of the adjustable distance component 1 2 and the adjustable distance component 2 3 can be adjusted as needed to support and fix the support plates 4 and change the distance between the two support plates 4. The installation component 5 consists of a fixed plate and a movable column. The specific structures of the adjustable distance component 1 2, the adjustable distance component 2 3, and the installation component 5 can be referred to the reference documents mentioned above.

In this example, the rainproof mechanism includes support rods 8, and there are several support rods 8 arranged in a rectangular pattern above the base 1. The lower end of the support rod 8 is inserted into a sliding groove 10 opened at the top of the base 1 and connected to a slider 9. Above the support rod 8, there is a rainproof plate 7 composed of a guide plate 11 and two symmetrically arranged guide plates 12. A water collection groove is opened at the top of the guide plate 12 on the side away from the guide plate 11.

Threaded cylinders 2 communicating with the water collection groove can also be detachably installed at symmetrical positions on the inner side wall of the guide plate 12. The threaded cylinders 2 are connected to the output end of the water pump 6 through a conduit. An adjustment groove is opened on the bottom surface of the guide plate 11. A slide block 15 is slidably installed in the adjustment groove. Several guide rods 14 are equidistantly arranged in the adjustment groove and pass through the slide block 15. Insert rods 23 are symmetrically arranged at the bottom of the slide block 15. The lower end of rod 23 is inserted into the slot at the top of support rod 8. Support rod 8 is connected to rod 23 via a fixing component. One side of slide 15 is fixedly connected to one end of guide plate 2 12, and the upper end of guide plate 2 12 is located at the bottom of guide plate 1 11. A chamber 22 is opened inside the middle part of slide 15. A push rod 16 is provided at the lower end of slide 15, and a baffle 17 is connected to the upper end of push rod 16 inside the chamber 22.

A slide rod 21 that passes through the two locking rods 20 is fixedly installed inside the chamber 22. Several locking slots that fit the locking rods 20 are symmetrically opened on the outer wall of guide rod 14 located in the middle. The rainproof mechanism allows the length of rainproof plate 7 to be adjusted according to actual use needs, making it more applicable, more convenient to use, and more practical. In this example, guide plate 11 and guide plate 2 are respectively provided with guide channel 1 and guide channel 2 on their tops. The bottom surface of guide channel 1 is arc-shaped, and guide channel 2 is connected to the water collection tank so that rainwater can be guided and collected into the water collection tank and then diverted to the rainwater well or sewage well on the municipal road through the threaded cylinder external pipe.In this example, the slide 15 has a T-shaped structure, the two ends of the connecting rod 19 are hinged to the baffle 17 and the locking rod 20 respectively, and the two ends of the spring 18 are fixedly connected to the baffle 17 and the inner wall of the chamber 22 respectively, so as to transmit power and drive the locking rod 20 to move.

[0022] In this example, the fixing component includes a fixing sleeve 25, which is fixedly installed on one side of the upper part of the support rod 8. A rotating cylinder 28 is rotatably installed inside the fixing sleeve 25. A limiting ring 26 and a torsion spring 27 are fitted inside the fixing sleeve 25 on the outer wall of the rotating cylinder 28. The limiting ring 26 is located on the side of the fixing sleeve 25 away from the support rod 8. The two ends of the torsion spring 27 are fixedly connected to the limiting ring 26 and the fixing sleeve 25, respectively. A fixing pin 24 is provided on one side of the support rod 8. The fixing pin 24 passes through the insert rod 23 and the support rod 8 and passes through the rotating cylinder 28. A limiting block 29 is symmetrically provided on the inner wall of the rotating cylinder 28 near the support rod 8. A rail groove 30 adapted to the limiting block 29 is symmetrically opened on the outer wall of the fixing pin 24. The fixing component facilitates the connection or disassembly of the rainproof plate 7 and the support rod 8, and facilitates their assembly. In this example, the limiting ring 26 is movably connected to the inner wall of the fixing sleeve 25, and the fixing pin 24 is L-shaped to guide and limit the limiting block 29.

[0023] The working principle of this utility model is as follows: In use, by adjusting the adjustment components 1 and 2 according to actual needs, the support plate 4 is adjusted to ensure that the support plate 4 is tightly fitted to the pit wall. Then, the lower end of the support rod 8 and the slider 9 can be slidably installed into the groove 10 on the base 1. After that, the combined length of the guide plate 11 and the two guide plates 2 is adjusted according to the distance between the two support plates 4. By pushing the push rod 16, the push rod 16 moves the baffle 17 upward and stretches the spring 18, causing the baffle 17 to push the connected connecting rod 19, thereby driving the two locking rods. Move the slider 20 outward along the slide bar 21, causing the locking rod 20 to move out of the slot on the guide rod 14. Then, drag the slide block 15 along the guide rod 14, causing the slide block 15 to drive the connected guide plate 12 to move synchronously to the appropriate position. Stop sliding the slide block 15, and then release the thrust applied to the push rod 16. Under the elastic force of the spring 18, the baffle 17 drives the push rod 16 to reset and move downward. The baffle 17 will drive the connecting rod 19 and the locking rod 20 to reset, so that the locking rod 20 can be locked into the corresponding slot on the outer wall of the guide rod 14 located in the middle position. This achieves the limiting and fixing of the slide block 15. Then, the rainproof plate 7 can be installed on top of the mounting assembly 5 between the two support plates 4, and the insertion rod 23 at the bottom of the slide block 15 can be inserted into the slot opened at the top of the support rod 8. Then, the rotating cylinder 28 is turned to drive the limiting block 29 to rotate 90 degrees. At the same time, the rotating cylinder 28 will drive the limiting ring 26 to torsion spring 27. Then, one end of the fixing pin 24 passes through the support rod 8 and the insertion rod 23, and the other end of the fixing pin 24 passes through the rotating cylinder 28, so that the limiting block 29 is inserted into the rail groove 30 opened on the outer wall of the fixing pin 24, until one end of the fixing pin 24 is in contact with the support rod 8. After assembly, the torque applied to the rotating drum 28 is released, causing the limiting ring 26 to drive the rotating drum 28 to reset and rotate under the torque of the torsion spring 27. This causes the rotating drum 28 to drive the connected limiting block 29 to reset and move within the rail groove 30, thereby achieving the restriction and fixation of the fixing pin 24. This completes the connection and fixation between the support rod 8 and the rainproof plate 7. When disassembling, repeat the above steps to twist the rotating drum 28, causing the rotating drum 28 to drive the limiting block 29 to rotate 90 degrees. Then, the fixing pin 24 is pulled out, and the rainproof plate 7 can be pulled up to separate the insert rod 23 from the support rod 8. This method is convenient to use and has greater practicality.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
