Description

Technical Field

[0001] This utility model relates to the field of construction sludge removal technology, specifically a non-excavation pipeline construction sludge removal device. Background Technology

[0002] Trenchless pipeline construction is a technology that allows for the laying, repair, or replacement of underground pipelines without extensive surface damage. Through methods such as horizontal directional drilling, pipe jacking, and pipe ramming, various underground pipeline projects can be completed without affecting surface traffic, buildings, or the surrounding environment. It is widely used in water supply and drainage, gas, and power industries. During construction, if the groundwater level is high or an aquifer is encountered, water mixes with the excavated soil to form mud. Improper subsequent mud treatment can lead to the separation of water and soil particles, causing the mud to settle and form silt, which may remain inside the pipeline or in the construction area.

[0003] Sludge and wastewater are discharged directly into the sewer pipes. The large solid particles such as gravel and sludge in the sludge can easily clog the pipes, affecting the normal operation of the sewer system, increasing pipe maintenance costs and the difficulty of unclogging. The muddy water that gushes out during construction is directly scattered on the construction site without treatment, making the ground dirty and messy, with gravel, sludge and other debris accumulating, affecting the subsequent construction, increasing the complexity and difficulty of construction, and reducing construction efficiency. Without filter boxes and settling boxes to intercept and filter impurities in the wastewater, workers have to spend a lot of time and energy cleaning up the muddy water and debris on the ground, increasing the difficulty and workload of subsequent garbage removal, and increasing the overall construction cost.

A handle is fixedly connected to the top of the closing plate, and a retaining seat is sleeved on the outer ring of the closing plate. The retaining seat is fixedly connected to the top of the processing box.

[0012] Preferably, the sealing assembly includes a bottom sealing plate, which is snapped into the bottom of the filter cake box and the settling box. A pull rod is fixedly connected to the front side of the bottom sealing plate, and a slot is opened below the pull rod at the bottom of the filter cake box and the settling box.

[0013] Preferably, the positioning component includes a fixed box, which is fixedly connected to the bottom front side of the filter cake box and the settling box. A slide cylinder is slidably connected inside the fixed box. A compression spring is fixedly connected inside the top of the slide cylinder.

The positioning rod passes downward through the filter cake box and the settling box and engages with the front side of the bottom sealing plate. A lever is fixedly connected inside the front side of the slide cylinder. The front sides of the filter cake box and the settling box have grooves corresponding to the positions of the levers.

[0014] Compared with the prior art, this utility model provides a non-excavation pipeline construction sludge cleaning device, which has the following beneficial effects:

[0015] 1. This trenchless pipeline construction sludge cleaning device, through its filter mechanism, allows for the initial filtration of the muddy water entering through the inlet pipe, intercepting large solid particles such as gravel in the muddy water flowing out during construction. Meanwhile, multiple settling tanks settle the mud in the wastewater. The liquid inlets and pipes on both sides are positioned at a high level, preventing the water flow from impacting the settling mud at the bottom. Simultaneously, the mud entering the settling tanks settles to the bottom under its own weight. The filter and settling tanks actively intercept and filter impurities in the wastewater, preventing it from scattering directly on the construction surface after it flows out, reducing the difficulty of subsequent waste cleanup. Furthermore, it prevents the discharged wastewater from clogging the underground pipelines, increasing the cleanliness of the work area during trenchless operations.

[0016] 2. This trenchless pipeline sludge cleaning device, through its bottom sealing mechanism, uses a sliding cylinder driven by a compression spring to move the positioning rod downwards and engage with the bottom sealing plate. This positioning prevents the bottom sealing plate from detaching from the filter cake box or settling box after installation, ensuring the sealing of the bottom of the filter cake box and settling box. This prevents debris from falling out of the filter cake box and settling box, facilitating the disassembly and assembly of the filter cake box and liquid inlet by workers. Workers can also easily disassemble the bottom sealing plate by simply moving the lever upwards and then pulling the lever forwards, making it convenient to clean the debris from the filter cake box and settling box.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] This utility model provides a technical solution:

[0028] Example 1

[0029] Combination Figures 1 to 5 A non-excavation pipeline construction sludge cleaning device includes a treatment box 3, an inlet pipe 31 fixedly connected to the top left side of the treatment box 3, an outlet pipe 32 fixedly connected to the bottom right side of the treatment box 3, a support leg 4 fixedly connected to the bottom of the treatment box 3, a sludge filter mechanism 1 installed inside the top of the treatment box 3, and a bottom sealing mechanism 2 installed inside the bottom of the sludge filter mechanism 1.

[0030] The filter cake mechanism 1 includes a filter cake assembly 11, a settling assembly 12, an isolation assembly 13, and a closing assembly 14. The filter cake assembly 11 is located on the left side of the top of the processing tank 3. The settling assembly 12 is located on the right side of the filter cake assembly 11 in the top of the processing tank 3. The isolation assembly 13 is located on the left and right sides of the filter cake assembly 11 and the settling assembly 12 in the processing tank 3. The closing assembly 14 is located on top of the filter cake assembly 11 and the settling assembly 12.

[0031] The filter cake assembly 11 includes a filter cake box 1101, which is snapped into the top left side of the processing tank 3. An inlet 1102 is provided on the left side of the filter cake box 1101 corresponding to the position of the inlet pipe 31. Screen grooves 1103 are provided on both the left and right sides of the filter cake box 1101. The settling assembly 12 includes a settling box 1201, which is snapped into the top of the processing tank 3 and located to the right of the filter cake box 1101. Exhaust ports 1202 are provided on the top of both the left and right sides of the settling box 1201. The isolation assembly 13 includes a hollow partition 1301, which is fixedly connected inside the processing tank 3 between the filter cake assembly 11 and the settling assembly 12. The inner side of the hollow partition 1301... A liquid inlet 1202 is fixedly connected to a liquid outlet 1302. A single-layer partition 1303 is provided on the right side of the hollow partition 1301. The single-layer partition 1303 is fixedly connected inside the treatment tank 3. The left side of the single-layer partition 1303 is attached to the right side of the rightmost settling tank 1201. A hole is opened on the top of the single-layer partition 1303 corresponding to the liquid outlet 1202. The closing assembly 14 includes a closing plate 1401. The closing plate 1401 is fixedly connected to the top of the filter cake box 1101 and the settling tank 1201. A handle 1402 is fixedly connected to the top of the closing plate 1401. A retainer 1403 is sleeved on the outer ring of the closing plate 1401. The retainer 1403 is fixedly connected to the top of the treatment tank 3.

[0032] Furthermore, when the device is in use, the filter box 1101 performs preliminary filtration of the mud and water entering through the inlet pipe 31, intercepting large solid particles such as gravel in the mud and water flowing out during the construction process. Meanwhile, the multiple settling boxes 1201 settle the mud in the sewage. The liquid outlets 1202 and liquid pipes 1302 on both sides are located at high positions, so that the water flow will not impact the mud settling at the bottom. At the same time, the mud entering the settling box 1201 can sink to the bottom of the settling box 1201 by its own weight. The filter box 1101 and the settling box 1201 actively intercept and filter impurities in the sewage, so that the sewage will not directly scatter on the construction ground after it flows out, reducing the difficulty of subsequent garbage cleaning. At the same time, it will prevent the sewage from flowing into the underground pipes and causing blockage of the sewer pipes, increasing the cleanliness of the working area during trenchless operations.

[0033] Example 2

[0034] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 Furthermore, based on Embodiment 1, the bottom sealing mechanism 2 includes a sealing component 21 and a positioning component 22. The sealing component 21 is disposed at the bottom of the filter cake assembly 11 and the settling assembly 12, and the positioning component 22 is disposed above the sealing component 21.

[0035] The sealing assembly 21 includes a bottom sealing plate 2101, which is snapped into the bottom of the filter cake box 1101 and the settling box 1201. A pull rod 2102 is fixedly connected to the front side of the bottom sealing plate 2101. A slot is formed below the pull rod 2102 at the bottom of the filter cake box 1101 and the settling box 1201. The positioning assembly 22 includes a fixing box 2201, which is fixedly connected to the front side of the bottom of the filter cake box 1101 and the settling box 1201. A sliding cylinder 2202 is slidably connected inside 01. A compression spring 2203 is fixedly connected inside the top of the sliding cylinder 2202. A positioning rod 2204 is fixedly connected to the bottom of the sliding cylinder 2202. The positioning rod 2204 passes downward through the filter cake box 1101 and the settling box 1201 and is engaged with the front side of the bottom sealing plate 2101. A lever 2205 is fixedly connected inside the front side of the sliding cylinder 2202. The front sides of the filter cake box 1101 and the settling box 1201 are provided with grooves corresponding to the positions of the lever 2205.

[0036] Furthermore: Under the action of the compression spring 2203, the slide cylinder 2202 drives the positioning rod 2204 to move downward and engage with the bottom sealing plate 2101 to position the bottom sealing plate 2101. This prevents the bottom sealing plate 2101 from detaching from the filter cake box 1101 or the settling box 1201 after installation, ensuring the sealing of the bottom of the filter cake box 1101 and the settling box 1201. This prevents the garbage entering the filter cake box 1101 and the settling box 1201 from falling out, making it easier for workers to disassemble and assemble the filter cake box 1101 and the liquid inlet 1102. At the same time, workers only need to push the lever 2205 upward and then pull the pull rod 2102 forward to complete the disassembly of the bottom sealing plate 2101, making it easier for workers to clean the garbage in the filter cake box 1101 and the settling box 1201.

[0037] In actual operation, when this device is used, the sewage generated during the trenchless construction process enters the treatment tank 3 through the inlet pipe 31. First, it enters the filter cake box 1101 through the inlet 1102. Then, the solid impurities in the sewage are intercepted and cannot leave the filter cake box 1101. The remaining mud and sewage continue to pass through the liquid pipe 1302 to the right and enter the settling tanks 1201 in sequence. The mud in the settling tank 1201 falls down and settles to the bottom of the settling tank 1201 by its own weight. After the remaining sewage is separated from the mud, it continues to pass through the single-layer partition 1303 to the right and is discharged into the sewer pipe through the outlet pipe 32.

[0038] When cleaning the waste and sludge intercepted inside the filter cake box 1101 or settling box 1201, the worker first pulls the handle 1402 upwards. The upward movement of the handle 1402 moves the filter cake box 1101 or settling box 1201 upwards, disengaging it from the processing box 3. Then, the worker moves the filter cake box 1101 or settling box 1201 above the waste processing or storage equipment. Next, the worker moves the lever 2205 on the front of the filter cake box 1101 or settling box 1201 upwards. The upward movement of the lever 2205 drives the fixed position via the slide cylinder 2202. Positioning lever 2204 moves upward and retracts into the fixed box 2201, disengaging from the bottom sealing plate 2101. Then, the worker pulls lever 2102 forward, which moves the bottom sealing plate 2101 forward, disengaging it from the filter cake box 1101 or settling box 1201 and releasing the seal on the bottom of the filter cake box 1101 or settling box 1201. At this point, the sludge in the filter cake box 1101 or settling box 1201 falls downward under gravity, thus completing the cleaning of the sludge in the filter cake box 1101 and settling box 1201.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
