Description

Technical Field

[0001] The utility model relates to the technical field of sluice pressure measuring tube dredging, in particular to a sluice pressure measuring tube dredging device which is easy to install. Background Art

[0002] Monitoring and analyzing sluice uplift pressure is a key component of sluice safety monitoring and a key indicator for measuring sluice facility safety. Currently, sluice uplift pressure monitoring typically relies on buried piezores to monitor the water level within the pipe. However, even in sluices currently in operation, it's common for piezores to not meet regulatory requirements. For example, some sluices were designed with pre-buried piezores, while others experienced blockages due to inadequate protective measures during construction, resulting in concrete falling into the pipes. Furthermore, some piezores may have lost caps during operation, causing sediment and other debris to enter and cause blockages. Heavy rainfall may also cause gravel and soil to wash into the pipes, leading to blockages.

[0003] For cleaning and repairing piezometric tubes in water conservancy projects, large-scale projects often use a combination of high-lift, low-flow submersible pumps, air compressors, and pipe dredging machines. However, during the cleaning process, concrete often falls into the piezometric tubes, causing blockages. Existing equipment often relies on drilling fixation, which can easily damage the sluice structure. Furthermore, after construction is completed, most fixings are left on the sluice, causing waste. Therefore, improvements to existing sluice piezometric tube dredging devices are still needed.

[0004] To address the above issues, the applicant previously applied for a Chinese utility model patent (application number: 202422014749.3, title: A water gate pressure gauge tube repair device for small working areas). The pressure gauge tube repair technology proposed in this application is mainly applicable to gate pier scenarios with guardrails. Its core idea is to fix the device by pressing the clamping plate to the bottom of the guardrail, and then press the supporting piles against the gate pier to achieve zero drilling fixation and reduce damage to the gate pier.

[0005] This repair method mainly relies on the guardrails of the gate piers themselves and is not applicable to gate piers without guardrails. Therefore, it is urgent to propose a piezometer pipe dredging and repair technology suitable for gate piers without guardrails. Summary of the Invention

[0031] refer to Figures 1-8 In order to solve the problem that drilling and fixing will damage the sluice structure, this embodiment proposes a sluice pressure measuring pipe dredging device that is easy to install, which is used to dredge the pressure measuring pipe on the gate pier B11. A pipe cap B2 is provided at the pipe opening on the top of the pressure measuring pipe. The pipe cap B2 is fixed to the gate pier B11 by an expansion bolt B3. When dredging the pressure measuring pipe, it is necessary to loosen the expansion bolt B3 and remove the pipe cap B2. At this time, the loosened expansion bolt B3 can be used as a fixing part to fix the dredging device; the dredging device includes: a vertically arranged support foot Pile B4: The bottom end of support pile B4 is connected to base B43, which is connected to pier B11 via a fixed assembly. Mounting block B5 is slidably connected to support pile B4 and can slide vertically on support pile B4. Mounting block B5 has a vertical through-hole B54, into which a drive gear B51 is rotatably connected. A vertical rack B41 is fixedly connected to the side wall of support pile B4. Drive gear B51 and vertical rack B41 cooperate to drive mounting block B5 to slide vertically along support pile B4. A guide slide block B52 is fixedly connected to the inner wall of mounting block B5. Slide block B52 can slide vertically within a slot B42, which is defined in the side wall of support pile B4. Drive gear B51 is connected to a rotating handle B53; rotating the handle B53 rotates drive gear B51. The drilling rig body B6 is connected to the mounting base B5; the drilling rig body B6 is driven and connected to a drill rod B7 for clearing the pressure measuring tube. The drill rod B7 includes several drill rod units B71, and adjacent drill rod units B71 are threadedly connected; a drill bit B10 or a wire cleaning head B11 for cleaning after clearing is completed is threadedly connected to the bottom of the drill rod B7 as needed.

[0032] The fixing assembly includes a fixing bracket B8, which fits over the pressure measuring tube and is secured to the gate pier B11 using expansion bolts B3 attached to the fixing cap. A jacking bolt B9 is threaded onto the fixing bracket B8, securing the base B43 to the gate pier B11. The base B43 has a positioning hole B44, and a baffle B91 is fixed to the center of the jacking bolt B9. The bottom of the jacking bolt B9 engages with the positioning hole B44, compressing the base B43 through the baffle B91.

[0033] The fixing frame B8 includes a bottom plate B81, a top plate B87 and a side plate B84 connecting the bottom plate B81 and the top plate; a pressure measuring tube hole B82 is respectively opened on the bottom plate B81 and the top plate B87, and a number of fixing holes B83 are opened around the pressure measuring tube hole B82 of the bottom plate B81 corresponding to the expansion bolts B3, and the expansion bolts B3 are installed on the fixing holes B83, and the expansion bolts B3 are fixed on the gate pier B11; an installation groove B85 is opened on the top plate B87, and the supporting foot pile B4 can slide in the installation groove B85, and one end of the installation groove B85 is connected to the pressure measuring tube hole B82; at least two threaded tightening holes B86 are opened on the top plate, and tightening bolts B9 are installed on the threaded tightening holes B86.

[0034] Directions:

[0035] First, install the drill rod unit B71 and drill bit B10 according to the depth of the piezometric tube. After installation, loosen the expansion bolt B3, remove the piezometric tube cap B2, put the fixing frame B8 on the piezometric tube mouth, and tighten the expansion bolt B3 to fix the fixing frame B8 on the gate pier B11; then push the dredging device along the installation groove B85, so that the drill rod B7 is concentric with the piezometric tube, turn the rotating handle B53, lower the drill rod B7, and wait until the bottom of the drill bit B10 contacts the concrete block, start the drilling rig, and dredge the piezometric tube.

[0036] Steps for unclogging the pressure tube:

[0037] 1. Check the sluice gate design drawings: According to the construction drawings, clarify the design requirements of the pressure measuring tube, such as: pressure measuring tube structure, layout of water inlet and water diversion sections, pipe depth, pressure measuring tube manufacturing materials and filter materials, etc.

[0038] 2. Measuring the depth of the pressure tube: Use a depth sounder to measure the actual depth of the pressure tube, and then compare it with the construction design depth to preliminarily determine the siltation depth.

[0039] 3. Cleaning of pressure measuring tube: Use a submersible pump with large lift and small flow, an air compressor and a pipe dredging machine in combination.

[0040] ① The water pump (h ≥ 150m, Q ≥ 3m3 / h) is connected to the D20 galvanized steel pipe through a high-pressure hose. A φ6mm water-permeable hole is drilled in the 500mm lower section of the galvanized steel pipe. There are 6 holes around the circumference with a spacing of 50mm, staggered in a plum blossom shape. The bottom of the galvanized steel pipe is pressed into a "duckbill" shape with a 5mm opening.

[0041] ② The 1.6MPa air compressor is connected to a high-pressure soft air pipe. The air pipe is slightly shorter than the galvanized steel pipe by 300mm and is fixed on the surface of the galvanized steel pipe. The pressure of the air supply pipe depends on the siltation in the pipe and is generally controlled at 0.005~0.010MPa.

[0042] ③ Insert the steel pipe directly into the piezometric tube, keeping the bottom of the pipe approximately 0.3m from the siltation surface to ensure the overflow velocity and safety of the piezometric tube. After turning on the pump, pump the pipe up and down, directing high-pressure water from the pipe's "duckbill" to impact the silt within the piezometric tube. The outlet at the bottom of the pipe ejects high-pressure water, impacting the silt at the piezometric tube's inlet. If the pipe encounters hard objects or severely compacted silt, forcefully lift the galvanized steel pipe downward to break up or loosen the hard objects and silt, allowing them to be flushed out of the pipe opening. Once water is supplied to a certain volume, the air compressor increases air flow from low to high, directing auxiliary water flow upward through the obstruction and overflowing from the piezometric tube opening, bringing mud, sand, and small rocks within the pipe with it.

[0043] ④ After flushing with pressure until clear water overflows for a period of time, measure the pipe depth again. If it has not reached the designed construction depth, it means that there are still debris such as stones. Use a pipe dredging machine and a special steel dredging head to break up or loosen hard objects and sediment. Then use pressure water flushing to flush hard objects such as gravel and sediment out of the pipe until the pipe depth reaches the designed depth.

[0044] 4. Cleaning the water inlet: After the cleaning depth reaches the designed depth, clean the water inlet of the piezometric tube (straight tube). Replace the dedicated wire cleaning head B11 and use the high-speed rotating wire cleaning head B11 to clear the "scaling" and other blockages in the water inlet of the piezometric tube's permeable section. Then flush with pressurized water to restore the piezometric tube's permeability.

[0045] 5. Piezometric Tube Unclogging: If the piezometric tube still fails to reach the designed depth after well flushing, this indicates a blockage caused by concrete falling into the tube during construction. Depending on the diameter of the piezometric tube, a conveniently installed sluice piezometric tube unclogging device (described in this embodiment) can be used to remove the trapped concrete. Once the designed depth is reached, the dedicated wire cleaning head B11 is replaced and used at high speed to clear the blockage at the water inlet of the horizontal section of the segmented piezometric tube or the water inlet hole of the permeable section of the straight piezometric tube. The tube is then flushed with pressurized water to restore the permeability of the piezometric tube.

[0046] 6. Piezometric tube modification: The middle piezometric tube of most sluice gates is a straight tube structure. Once concrete falls into the tube during construction, it causes "blockage". Usually, the water inlet hole of the water inlet section is also "blocked". If the water permeability of the piezometric tube cannot be restored through the above steps, the original piezometric tube needs to be modified. A sluice piezometric tube dredging device that is easy to install in this embodiment is used to penetrate the "sealing cap" at the bottom of the original piezometric tube and penetrate 500mm into the stratum. Then, according to the design requirements of the piezometric tube, a new piezometric tube is made and inserted, and 5-8m of washed medium sand is backfilled. Then, concrete is poured to seal the tube mouth.

Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without expending creative work are still within the scope of protection of the utility model.
