Description

Technical Field

[0001] This invention relates to the field of engineering support devices, and in particular to the support structure for pump station foundation pits. Background Technology

[0002] Currently, the layout types of water intake pumping stations in water conservancy projects typically include surface type, semi-buried type, underground type, and other types. Nowadays, other types of pumping stations such as vertical shaft pumping stations, cable car pumping stations, floating pumping stations, and submersible pumping stations can be used. In actual application, it is necessary to select the appropriate pumping station layout type according to different terrain, geology, water level, and external stress conditions.

[0003] Pump station foundation pit support devices typically use a combination of pillars and concrete walls to comprehensively support the pit, preventing water leakage and the collapse of surrounding soil. When installing pillars, holes are first drilled in the foundation, and then the piles are inserted into these holes. Reinforcing steel and concrete are then used to seal and support the pit. However, reinforcing steel and concrete cannot be poured immediately after the piles are inserted. Therefore, it is not easy for construction workers to detect when a pile falls downwards. For this reason, a pump station foundation pit support structure is needed to provide early warning of pile falls and prevent the piles from extending beyond the specified length. Summary of the Invention

[0004] The purpose of this invention is to provide a pump station foundation pit support structure that overcomes the shortcomings of not providing early warning and protection against pile sinking.

[0005] The technical solution to achieve the above objectives is: a pump station foundation pit support structure, including a spillway plate and a surrounding plate, wherein the surrounding plate has multiple pile holes, an early warning mechanism is provided on the surrounding plate, a pile insertion mechanism is inserted into the pile holes, a starting mechanism is provided at the top of the pile insertion mechanism, a steel frame is connected to the inner side wall of the surrounding plate, and an opening is provided at the top of both the spillway plate and the surrounding plate.

[0006] Preferably, the warning mechanism includes a connecting groove, a push switch, and an alarm. The top of the enclosure has multiple connecting grooves, the inner sidewall of the connecting groove is connected to the push switch, and the top of the enclosure is connected to the alarm.

[0007] Preferably, the push switch and the alarm are electrically connected, and the two ends of the connecting groove are respectively connected to two adjacent insertion holes.

[0008] Preferably, the insertion mechanism includes a base tube, a first inner slot, a first insertion hole, an insertion tube, an extension tube, a slot, an insertion rod, an inner insertion plate, a second insertion hole, and a second inner slot. The bottom end of the base tube is connected to the insertion tube, the top end of the base tube has multiple first insertion holes, the top end of the inner sidewall of the base tube has a first inner slot, the top end of the extension tube has multiple slots, the bottom end of the slots has a second insertion hole, the top end of the inner sidewall of the extension tube has a second inner slot, the bottom end of the extension tube is connected to multiple insertion rods, and the bottom end of the inner sidewall of the extension tube is connected to an inner insertion plate.

[0009] Preferably, the diameter of the first inner slot is equal to the diameter of the second inner slot, the diameter of the extension tube is equal to the diameter of the bottom tube, and the upper end of the inner wall of the second insertion hole is provided with a threaded groove.

[0010] Preferably, the cannula is conical in shape, and the diameter of the bottom end of the cannula is smaller than the inner diameter of the bottom tube.

[0011] Preferably, the starting mechanism includes a mounting ring, a locking block, a round hole, a fixing block, a fixing pin, a connecting block, a limiting pin, and an adjusting rod. The bottom end of the side wall of the mounting ring is connected to multiple locking blocks. The side wall of the locking block has a round hole and is inserted into a locking groove. The side wall of the fixing block is threaded to the fixing pin. The side wall of the connecting block is threaded to the limiting pin. One end of the connecting block is threaded to an adjusting rod. The adjusting rod is located directly above the push switch, and the end of the connecting block near the adjusting rod is located inside the connecting groove.

[0012] Preferably, the height of the locking block is equal to the height of the mounting ring, the height of the mounting ring is equal to the depth of the second inner slot, and the sum of the heights of the fixing block and the locking block is equal to the depth of the slot.

[0013] The beneficial effects of this invention are:

[0014] 1) When the extension pipe and the bottom pipe are sinking, since the extension pipe at the top is connected to the connecting block and the mounting ring as a whole, the extension pipe drives the mounting ring to move downward, the mounting ring drives the connecting block to move downward, and the connecting block drives the adjusting rod to move downward, thereby pressing the press switch and activating the alarm to remind the workers that the pile pipe consisting of the extension pipe and the bottom pipe is sinking.

[0015] 2) Align the insert rod on the upper extension tube and insert it into the second insertion hole on the lower extension tube. At the same time, insert the inner insert plate on the upper extension tube into the second inner slot on the lower extension tube, and cover the inside of the slot. This completes the connection of the two extension tubes and achieves the extension connection effect of the insertion pipe, thereby matching the depth of the insertion hole.

[0016] 3) Insert the mounting ring into the second inner slot on the extension tube at the top. Simultaneously, align the locking block with the slot and the round hole with the second insertion hole. Insert the mounting ring into the second inner slot and the locking block into the slot. Insert the fixing block into part of the slot and align the fixing pin on the fixing block with the round hole. Pass the fixing pin through the round hole and thread it into the second insertion hole to clamp the locking block, thus connecting the mounting ring and the second extension tube as one unit. Then, insert the connecting block into one of the remaining slots. Connect the two ends of the connecting slot to two adjacent insertion holes, allowing the connecting block to be placed in the slot and the connecting slot. At this point, align the limiting pin with the second insertion hole, screw the limiting pin in and through the connecting block, and then screw the limiting pin into the second insertion hole. This connects the connecting block, mounting ring, and extension tube as one unit, achieving the effect of convenient installation of the starting mechanism. Attached Figure Description

[0038] The invention will now be further described with reference to the accompanying drawings.

[0039] Reference Appendix Figure 1-18The pump station foundation pit support structure includes a spillway plate 1 and a surrounding plate 2. Multiple pile holes 3 are provided on the surrounding plate 2, and an early warning mechanism 4 is installed on the surrounding plate 2. Pile insertion mechanisms 5 are inserted into the pile holes 3, and a starting mechanism 6 is installed at the top of the pile insertion mechanism 5. A steel frame 7 is connected to the inner side wall of the surrounding plate 2 to support the surrounding plate 2. The steel frame 7 is a square frame welded from perforated steel plates, with triangular corners to improve its stability. The steel frame 7 has two layers, connected together by steel rods. Openings 8 are provided at the top of both the spillway plate 1 and the surrounding plate 2 to facilitate earthwork excavation. Compared to conventional support structures, the conventional support at the cap beam is eliminated, and the support at the cap beam is moved down to the middle of the surrounding plate 2, increasing the amount of steel reinforcement in the steel frame 7 to improve the support and fixation effect.

[0040] Reference Appendix Figure 2-17 The insertion mechanism 5 includes a base tube 501, a first inner slot 502, a first insertion hole 503, an insertion tube 504, an extension tube 505, a slot 506, an insertion rod 507, an inner insertion plate 508, a second insertion hole 509, and a second inner slot 510.

The top end of the inner side wall of the base tube 501 has a first inner slot 502. The top end of the extension tube 505 has multiple slots 506. The bottom end of the slots 506 has a second insertion hole 509. The extension tube 505 has a second inner slot 510 at the top of its inner sidewall. The bottom of the extension tube 505 is connected to multiple insertion rods 507. The bottom of the inner sidewall of the extension tube 505 is connected to an inner insertion plate 508. The diameter of the first inner slot 502 is equal to the diameter of the second inner slot 510. The diameter of the extension tube 505 is equal to the diameter of the bottom tube 501. The upper end of the inner wall of the second insertion hole 509 is provided with a threaded groove. The insertion tube 504 is conical in shape. The bottom diameter of the insertion tube 504 is smaller than the inner diameter of the bottom tube 501. The inner insertion plate 508 is cylindrical in shape.

[0041] Insert the bottom tube 501 into the pile hole 3, so that the bottom tube 501 drives the insertion tube 504 into the ground. The cone shape of the insertion tube 504 makes it easy to make the bottom tube 501 stand upright in the pile hole 3. Then, align the insertion rod 507 on the extension tube 505 with the first insertion hole 503. Then, insert the insertion rod 507 into the first insertion hole 503 to make it easy to align the extension tube 505 with the bottom tube 501. At the same time, insert the inner plate 508 into the first inner slot 502 to complete the connection between the bottom tube 501 and the adjacent extension tube 505.

[0042] Next, align the insertion rod 507 on the upper extension tube 505 and insert it into the second insertion hole 509 on the lower extension tube 505. At the same time, insert the inner plate 508 on the upper extension tube 505 into the second inner slot 510 on the lower extension tube 505, thus covering the inside of the slot 506. This completes the connection of the two extension tubes 505, achieving the extension connection effect of the insertion pipe, thereby matching the depth of the insertion hole 3.

[0043] Reference Appendix Figure 10-16 The starting mechanism 6 includes a mounting ring 601, a locking block 602, a round hole 603, a fixing block 604, a fixing pin 605, a connecting block 606, a limiting pin 607, and an adjusting rod 608. Multiple locking blocks 602 are connected to the bottom end of the side wall of the mounting ring 601. The side wall of each locking block 602 has a round hole 603. The side wall of the locking block 602 is inserted into a locking groove 506. The side wall of the fixing block 604 is threadedly connected to the fixing pin 605. The side wall of the connecting block 606 is threadedly connected to the limiting pin 607. One end of the connecting block 606 is threadedly connected to the adjusting rod 608. The adjusting rod 608 is located at... Directly above the push switch 402, the end of the connecting block 606 near the adjusting rod 608 is located inside the connecting groove 401. The height of the locking block 602 is equal to the height of the mounting ring 601, and the height of the mounting ring 601 is equal to the depth of the second inner slot 510. The height of the fixing block 604 and the height of the locking block 602 are equal to the depth of the slot 506. Both the fixing block 604 and the connecting block 606 are provided with screw holes. The limit pin 607 and the adjusting rod 608 are threadedly connected to the connecting block 606 through the screw holes on the connecting block 606. The fixing pin 605 and the fixing block 604 are also threadedly connected through screw holes.

[0044] Insert the mounting ring 601 into the second inner slot 510 on the extension tube 505 at the top. Simultaneously, align the locking block 602 with the slot 506 and the round hole 603 with the second insertion hole 509, so that the mounting ring 601 is inserted into the second inner slot 510 and the locking block 602 is inserted into the slot 506. Insert the fixing block 604 into a portion of the slot 506, and align the fixing pin 605 on the fixing block 604 with the round hole 603, so that the fixing pin 605 passes through the round hole 603 and is threaded into the second insertion hole 509 to clamp and fix the locking block 602. This connects the mounting ring 601 and the second extension tube 505 into a single unit. Then, insert the connecting block 606 into the remaining slot. The slot 506 connects to two adjacent insertion holes 3 at both ends of the connecting slot 401, allowing the connecting block 606 to be placed in the slot 506 and the connecting slot 401. At this time, the limiting pin 607 is aligned with the second insertion hole 509, and the limiting pin 607 is screwed in and passes through the connecting block 606. Then, the limiting pin 607 is screwed into the second insertion hole 509, thereby connecting the connecting block 606, the mounting ring 601, and the extension tube 505 into one unit, achieving the effect of convenient installation of the starting mechanism 6. At the same time, reversing the above operation also facilitates the disassembly of the starting mechanism 6. At this time, rotating the adjusting rod 608 can adjust the distance between the bottom end of the adjusting rod 608 and the press switch 402, thereby achieving the effect of adjusting the sinking distance of the alarm trigger.
