Description

Technical Field

[0001] The present invention relates to the technical field of pipeline fixing, and in particular to a fixing device for a leachate lifting inclined pipe and a construction method thereof. Background Art

[0002] Leachate is the product of gravity flow of liquid in a solid waste landfill, mainly derived from precipitation and liquid contained in solid waste. The leachate lifting inclined pipe is located on the dam body and the base slope. The leachate lifting inclined pipe consists of an inclined section and a horizontal section connected to each other at the ends. The upper end of the inclined section extends upward along the slope of the base, and the horizontal section is placed in the collection pit between the dam body and the base slope.

[0003] Most of the existing technologies place the leachate lifting inclined pipe naturally on the slope of the flexible landfill. When the leachate lifting inclined pipe is placed naturally on the slope of the flexible landfill, there are problems such as easy slippage and deformation. Patent 108273822A discloses a leachate lifting inclined pipe well, specifically including a PE pipe and a dam body, a collection pit formed between the dam body and the base slope, the PE pipe consisting of an inclined section and a horizontal section connected to each other at the ends, the upper end of the inclined section extends upward along the slope of the base, and the horizontal section is placed in the collection pit, a matching guide rail is installed in the PE pipe, a pump truck is slidably set on the guide rail, a submersible sewage pump is provided on the pump truck, a traction chain is provided on the pump truck, one end of the delivery pipe is connected to the output end of the submersible sewage pump, and the other end of the delivery pipe extends outward from the inside of the PE pipe, when the accumulation of leachate in the PE pipe reaches a certain level, the submersible sewage pump and the delivery pipe are used to directly discharge the accumulated leachate from the collection pit, thereby eliminating the need to discharge the leachate through the dam by gravity drainage, that is, no special welding points are added to the HDPE geomembrane, thereby eliminating the damage of the geomembrane due to the design process, ensuring the anti-seepage performance of the landfill, but the PE pipe in this solution has the problem of easy slippage and deformation.

[0030] Reference Figure 1 , a fixing device for a leachate lifting inclined pipe, comprising:

[0031] The flange 1 is fixed to the first end of the leachate lifting inclined pipe 2.

[0032] Among them, the flange 1 is sleeved on the leachate lifting inclined pipe 2. The leachate lifting inclined pipe 2 and the flange 1 are both made of high-density polyethylene (HDPE). The connection methods of the leachate lifting inclined pipe 2 and the flange 1 include welding, one-piece molding, etc. The flange 1 is fixed on one end of the leachate lifting inclined pipe 2 located at the top of the base slope.

[0033] The clamp 3 is sleeved on the leachate lifting inclined pipe 2 and is located on the side of the flange 1 away from the first end. The leachate lifting inclined pipe 2 is located on the base slope 4.

[0034] Among them, the material of the hoop 3 is also high-density polyethylene (HDPE), which can be a whole circular ring, which is sleeved on the outer wall of the leachate lifting inclined pipe 2, and two outward-protruding threaded holes are provided on the outer wall of the circular ring, and a bolt is connected in each threaded hole. The hoop 3 can also be composed of two semi-circular rings buckled on the outer wall of the leachate lifting inclined pipe 2, and both ends of the two semi-circular rings are provided with protrusions. The two protrusions when buckled are detachably connected by bolts and nuts on both sides. The two second ends of the traction device 5 are detachably connected to the two sides of the hoop 3 respectively. When the bolts are tightened, the traction transposition is also tightened with the hoop 3, thereby pulling the leachate lifting inclined pipe 2 to prevent it from slipping and deformation during sliding.

[0035] The two traction devices 5 have two first ends on the same side that are detachably connected to the anchoring platform 6 of the garbage dam, and the two second ends on the same side of the two traction devices 5 are detachably connected to the two sides of the clamp 3 respectively. The two traction devices are used to tighten the leachate lifting inclined pipe.

[0036] During traction, the ends of the two traction devices 5 on the same side can be detachably connected on the anchoring platform 6 of the garbage dam, wherein the detachable connection includes anchoring, threaded connection, etc.

[0037] In a possible embodiment, two fixing columns are fixed on the anchoring platform 6 of the garbage dam. The two fixing columns include precast concrete piles 7 with a conical bottom. The two precast concrete piles 7 are detachably connected to the two first ends on the same side of the two traction devices 5.

[0038] In this embodiment, the anchoring platform 6 of the garbage dam is located at the top of the base slope 4, two precast concrete piles 7 are located on both sides of the center line of the leachate lifting inclined pipe 2, and the precast concrete piles 7 are connected to the clamp 3 located at the top of the leachate lifting inclined pipe 2 through a traction device 5.

[0039] In a possible embodiment, most of the two precast concrete piles 7 are buried on the anchoring platform 6 of the garbage dam, and two connecting blocks 7-1 are fixed on the top of the two precast concrete piles 7 respectively. Corner blocks 7-2 are fixed on the top of the two connecting blocks 7-1, and through holes 7-3 are provided on the two corner blocks 7-2.

[0040] In this embodiment, see Figure 2 Each connecting block 7-1 is a horizontal metal block, which is fixedly connected to the precast concrete pile 7 by bolts. The corner block 7-2 is a vertical irregular metal block, the bottom of which is welded to the horizontal metal block, and a through hole 7-3 is provided on the side wall of the irregular metal block. The metal block has high rigidity and can withstand large traction.

[0041] In a possible embodiment, each traction device 5 includes:

[0042] The steel wire rope 5-6 has an annular knot 5-1 at one end, and the annular knot 5-1 is passed through the through hole 7-3. The other end of the steel wire rope 5-6 is arranged in one end of the first connecting sleeve 5-2. The other end of the first connecting sleeve 5-2 is detachably connected to one end of the connecting column 5-3. The other end of the connecting column 5-3 is detachably connected to one end of the second connecting sleeve 5-4. The other end of the second connecting sleeve 5-4 is detachably connected to the bottom of the U-shaped fork 5-5. The U-shaped hole of the U-shaped fork 5-5 is fastened to the bolt of the clamp 3.

[0043] In this embodiment, see Figure 3The second connecting sleeve 5-4 is connected to the fork handle at the bottom of the U-shaped fork 5-5 by a threaded connection. The width of the U-shaped hole at the top of the U-shaped fork 5-5 is equivalent to the width of the bolt, and the bolt is clamped on both sides of the U-shaped hole of the U-shaped fork 5-5 when tightened, thereby fixing the other end of the traction device 5. In addition to being used for disassembling and replacing the wire rope 5-6 and the U-shaped fork 5-5, the second connecting sleeve 5-4 can also fine-tune the tightness of the wire rope 5-6.

[0044] In a possible embodiment, the angle formed by each traction device 5 and the leachate lifting inclined pipe 2 on the same side ranges from 15 degrees to 30 degrees.

[0045] In this embodiment, the angle formed between each traction device 5 and the leachate lifting inclined pipe 2 on the same side is in the range of 15 degrees.

[0046] A construction method for fixing a leachate lifting inclined pipe, referring to Figure 4 , methods include:

[0047] Step 101: Install a flange 1 on the top of the leachate lifting inclined pipe 2 near one end of the anchoring platform 6;
