Description

Technical Field

[0001] The invention belongs to the technical field of pollutant treatment engineering, and more specifically, relates to a vertical anti-seepage frame and a vertical anti-seepage wall construction method. Background Art

[0002] The vertical anti-seepage system of a solid waste landfill builds a sealing layer around the landfill, mainly utilizing the impermeable layer or weakly permeable layer under the landfill foundation, and constructs a vertical sealing layer on it, so as to control the landfill gas and waste leachate within the landfill, and also has the function of preventing the surrounding groundwater from flowing into the landfill; the vertical anti-seepage system of a landfill is based on the engineering and hydrogeological characteristics of the landfill, utilizing the independent hydrogeological units, impermeable or weakly permeable layers, etc. under the landfill foundation, and setting up vertical anti-seepage projects (such as anti-seepage walls, anti-seepage boards, grouting curtains, etc.) on one side or around the landfill, so as to seal the garbage leachate in the landfill for controlled discharge, prevent the leachate from penetrating into the surrounding area and polluting the groundwater and the uncontrolled release of landfill gas, and also has the function of preventing the surrounding groundwater from flowing into the landfill. Vertical anti-seepage is widely used in valley-type landfills.

[0003] GCL waterproof blanket, namely Sodium Bentonite Geosynthetic Clay Line, is a new type of waterproof material. It is made of natural sodium bentonite wrapped with two layers of geotextiles and reinforced with needle punching. Its anti-leakage mechanism is as follows: the sodium-based bentonite particles used in bentonite waterproof blanket can expand more than 24 times when exposed to water, forming a uniform colloid system with high viscosity and low filtration loss. Under the restriction of two layers of geotextiles, the bentonite changes from disorder to orderly expansion. The continuous water absorption and expansion result makes the bentonite layer itself dense, thus having a waterproof effect. When carrying out vertical anti-seepage construction, the hydraulic grab slot machine opens the slot and performs mud wall protection, and the GCL waterproof blanket is laid close to the outer slot wall. Finally, the underwater conduit of cement-bentonite wall material is poured, and finally a continuous GCL composite vertical flexible anti-seepage wall is formed. In the waterproofing method in which the GCL waterproof blanket is tightly attached to the side groove wall, the actual laying is difficult, and there will be gaps between the GCL waterproof blankets. When the GCL waterproof blankets are bonded only by adhesives, leakage gaps are likely to appear at the joints of the GCL waterproof blankets as the water pressure increases. Therefore, the actual anti-seepage effect is not high and the stability is insufficient.

[0004] After retrieval, patent CN218405316U discloses an anti-seepage treatment structure for danger removal and reinforcement of an earth-rock dam, which includes a support layer and an anti-seepage membrane layer arranged on the water-facing side of the support layer; the support layer includes a plurality of steel meshes, each steel mesh includes a frame body and a mesh body arranged in the hollow part of the frame body, and a splicing structure for splicing adjacent steel meshes is arranged on the frame body. This application has the effect of avoiding the over-stretching damage of the anti-seepage membrane caused by soil settlement, thereby avoiding the influence on the anti-seepage effect of the earth-rock dam.

[0006] However, due to the large size of the anti-seepage wall, the splicing between multiple GCL waterproof blankets needs to be realized, and the above patents cannot realize the adjustment of the size of the anti-seepage wall and the distance between multiple anti-seepage walls.

[0059] The following detailed description of exemplary embodiments of the present invention refers to the accompanying drawings, which form a part of the description, and in which exemplary embodiments of the present invention that can be implemented are shown as examples. Although these exemplary embodiments are described in sufficient detail to enable those skilled in the art to implement the present invention, it should be understood that other embodiments can be implemented and various changes can be made to the present invention without departing from the spirit and scope of the present invention. The following more detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but is only for the purpose of illustrating and not limiting the description of the characteristics and features of the present invention, so as to propose the best mode for performing the present invention and to enable those skilled in the art to implement the present invention. Therefore, the scope of the present invention is limited only by the appended claims.

[0060] It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0061] The following is combined with Figures 1 to 14 , the vertical anti-seepage frame of the present invention is described in detail:

[0062] Example

[0063] The following is combined with Figures 1 to 14 , the vertical anti-seepage frame and the vertical anti-seepage wall construction method of the present invention are described in detail:

[0064] In the existing anti-seepage treatment method, when treating a specific area, such as a dam or pollutant, there is generally a corresponding anti-seepage treatment barrier layer at the bottom of the specific area, and there will be a vertical anti-seepage layer around the specific area. As the service life increases, leakage will still occur at the vertical anti-seepage layer, so it is necessary to repair the vertical anti-seepage layer to prevent further leakage. During the repair of the vertical anti-seepage layer, a trench can generally be excavated on the periphery of the pre-prepared vertical anti-seepage layer, and then a waterproof blanket can be laid and filled with anti-seepage bentonite to achieve the purpose of anti-seepage. However, in the above-mentioned anti-seepage treatment process, it is easy to have gaps when simply laying waterproof blankets, and the overlapping positions between the waterproof blankets are bonded by adhesives, and the service life is relatively low. When the water pressure in the specific area is too high or the pressure of the pollutants is too high, it is easy to leak from the overlapping gaps of the waterproof blankets. Therefore, the existing anti-seepage treatment still has a large instability factor.

[0065] Based on this, the present invention proposes a vertical anti-seepage frame, which includes:

[0066] The inner frame body 10 is in the shape of a rectangular frame as a whole;

[0067] The outer frame body 20 is installed on one side of the inner frame body 10 and matches the contour of the inner frame body 10;

[0068] GCL waterproof blanket 30, installed in the gap between the outer frame body 20 and the inner frame body 10;

[0069] A spacing adjustment unit, used to adjust the spacing between the inner frame body 10 and the outer frame body 20;

[0070] The width adjustment unit is used to adjust the width of the outer frame body 20 and the inner frame body 10 .

[0071] like Figure 3 and Figure 4 As shown, in one embodiment, the inner frame body 10 and the outer frame body 20 are both made of rigid rust-proof metal materials, and the inner frame body 10 and the outer frame body 20 are both rectangular frame-shaped. A GCL waterproof blanket 30 is provided in the frame area between the inner frame body 10 and the outer frame body 20. The GCL waterproof blanket 30 and the inner frame body 10 and the outer frame body 20 form an integral wall panel structure, which can effectively block the leakage of liquid pollutants or water flow.

[0072] At least two layers of GCL waterproof blankets 30 spaced apart from each other are provided in the vertical anti-seepage frame. When the first layer of GCL waterproof blanket 30 comes into contact with water flow or pollutants, the first layer of GCL waterproof blanket 30 can form a dense blocking layer, and the second layer of GCL waterproof blanket 30 can play a stabilizing role, thereby basically preventing water flow from penetrating.

[0073] During the actual construction process, a vertical trench is opened in a designated area in advance by trenching equipment, and the trench wall and trench bottom are covered with mud by mud circulation equipment, and the trench wall and trench bottom are cleaned, and then a waterproof blanket is laid at the bottom of the trench, and the vertical anti-seepage frame is hoisted into the trench by hoisting equipment, so that the vertical anti-seepage frames are arranged at intervals along the length direction of the trench, and anti-seepage bentonite is filled in the gap between the trench and the vertical anti-seepage frame, and the anti-seepage bentonite is compacted, and then the spacing between the inner frame body 10 and the outer frame body 20 of the vertical anti-seepage frame is adjusted by the spacing adjustment unit, so that the inner frame body 10 and the outer frame body 20 of the vertical anti-seepage frame are in full contact and abutment with the compacted anti-seepage bentonite to further improve the anti-seepage effect, and the width of the outer frame body 20 and the inner frame body 10 is adjusted by the width adjustment unit, so that the vertical anti-seepage frames are close to each other and squeezed close to each other, which plays a further sealing role to prevent pollutants or water from leaking from the joint position.

[0074] The outer frame body 20 and the inner frame body 10 are provided with sealing units at their bottom sides, and the sealing units are used for sealingly combining with the bottom of the groove.

[0075] The sealing unit may be a flexible structure with a certain degree of deformation capability to ensure tight connection between the bottom sides of the outer frame 20 and the inner frame 10 and the laid waterproof blanket, thereby avoiding leakage at the bottom of the vertical anti-seepage frame and the bottom of the trench.

[0076] To ensure the tight connection between the outer frame body 20 and the bottom side of the inner frame body 10 and the waterproof blanket laid, as Fig.13 As shown, the sealing unit includes a flexible sealing sheet 40, on which at least two groups of card grooves 41 are arranged, and the card grooves 41 are arranged along the length direction of the flexible sealing sheet 40. The bottom sides of the outer frame body 20 and the inner frame body 10 are clamped in the card grooves 41, and the flexible sealing sheet 40 is provided with a first telescopic section 42, and the cross-section of the first telescopic section 42 is wavy or sawtooth-shaped.

[0077] In one embodiment, see Fig. 9 , Fig.10 and Fig.13The flexible sealing sheet 40 is a flexible rubber or a corrosion-resistant steel sheet. The bottom sides of the outer frame body 20 and the inner frame body 10 are respectively clamped in two groups of card grooves 41 to avoid leakage. The cross-section of the first telescopic section 42 is wavy, which can make the first telescopic section 42 as a whole present a spring-like structure. Materials such as steel wire are embedded in the first telescopic section 42, so that the first telescopic section 42 is in a tightened state under normal conditions. When the distance between the outer frame body 20 and the inner frame body 10 becomes larger, the first telescopic section 42 is in an expanded state, so that the first telescopic section 42 can adapt to the change in the distance between the outer frame body 20 and the inner frame body 10, avoiding the occurrence of a gap between the vertical anti-seepage frame and the anti-seepage bentonite, so that the outer frame body 20 and the inner frame body 10 are fully combined with the anti-seepage bentonite.

[0078] In order to ensure that the GCL waterproof blanket 30 can play a strict anti-seepage effect, a plurality of groups of snap-in grooves 411 are provided on the flexible sealing sheet 40. One end of the GCL waterproof blanket 30 extends into the snap-in groove 411. A clamping cover plate 412 is provided on the snap-in groove 411. The clamping cover plate 412 is snapped on both sides of the GCL waterproof blanket 30. Through the cooperation of bolts or wedges, the GCL waterproof blanket 30 is tightened and sealed to avoid gaps.

[0079] In one embodiment, the lower end of the GCL waterproof blanket 30 extends into the snap-in groove 411 and is covered by the clamping cover plate 412, thereby ensuring the effective combination of the GCL waterproof blanket 30 and the entire inner frame body 10 and the outer frame body 20 to ensure the anti-seepage effect.

[0080] In order to realize the sliding guidance between the inner frame body 10 and the outer frame body 20 of the vertical anti-seepage frame, a spacing adjustment unit is provided between the inner frame body 10 and the outer frame body 20, and the spacing adjustment unit includes a guide rod 11 arranged on the inner frame body 10, and the guide rod 11 is perpendicular to the inner frame body 10 and is arranged in an array on the inner frame body 10, and a conduit 21 corresponding to the guide rod 11 is provided on the outer frame body 20, and through tubes 31 arranged corresponding to the conduits 21 are provided on both sides of the GCL waterproof blanket 30, and gaskets 311 are provided at the tube ends of the through tubes 31, and the gaskets 311 are abutted against the GCL waterproof blanket 30, and the two groups of gaskets 31 of the through tubes 31 are fixed as a whole.

[0081] Specifically, the through tube 31 includes an inner tube 312 and an outer tube 313. The inner tube 312 is a sealing protrusion provided on the outer wall of the conduit 21, and is tightly fitted with the outer wall of the conduit 21. The outer tube 313 is a protrusion provided on the outer wall of the guide rod 11, and is sleeved on the outer wall of the guide rod 11. The outer tube 313 is sleeved on the inner tube 312, and the inner tube 312 and the outer tube 313 are sealed to form a sliding fit.

[0082] In one embodiment, the number and position of the guide rods 11 on the inner frame body 10 correspond to the conduits 21 on the outer frame body 20, and the whole is arranged in an array shape. The through tubes 31 are provided on both sides of the GCL waterproof blanket 30, and the positions of the through tubes 31 are arranged corresponding to the positions of the conduits 21. Therefore, the conduits 21 pass through the through tubes 31, which can make the GCL waterproof blanket 30 in a flattened state, and thus make the GCL waterproof blanket 30 present a flattened sheet structure. When the GCL waterproof blanket 30 is combined with liquid pollutants or water flow, the GCL waterproof blanket 30 can form a dense protective film. The GCL waterproof blanket 30 is spaced on both sides, so that the inner frame body 10 and the outer frame body 20 can form a stable frame structure, thereby achieving vertical anti-seepage.

[0083] When it is necessary to adjust the distance between the inner frame body 10 and the outer frame body 20, the sealing protrusion provided on the outer wall of the conduit 21 is sealed against the inner wall of the through tube 31, thereby ensuring that the GCL waterproof blanket 30 presents a whole and ensures the overall sealing. Similarly, the outer wall of the guide rod 11 is provided with a protrusion, which is sealed against the inner wall of the conduit 21 to prevent liquid contaminated water from leaking out of the conduit 21.

[0084] When the vertical anti-seepage frame is recycled, the GCL waterproof blanket 30 that has previously played its role can be replaced with a new one, which significantly reduces the actual use cost.

[0085] In order to adjust the distance between the inner frame body 10 and the outer frame body 20, the distance adjustment unit also includes a wedge block 22 arranged between the inner frame body 10 and the outer frame body 20, the wedge block 22 is provided with an inclined surface, and a top pressure arc piece 23 is provided on the wedge block 22, and the top pressure arc piece 23 is abutted against the inclined surface of the wedge block 22.

[0086] Specifically, the wedge block 22 presents an inclined surface which is narrow at the top and wide at the bottom, and the top pressure arc piece 23 is in the shape of a groove plate. The inclined surface of the groove plate cooperates with the inclined surface of the wedge block 22. When the two sets of vertical anti-seepage frames are installed, the top pressure arc piece 23 abuts against the inclined surface of the wedge block 22, so that the distance between the inner frame body 10 and the outer frame body 20 can be increased, so that the inner frame body 10 and the outer frame body 20 are tightly combined with the anti-seepage bentonite on the inner and outer sides to avoid leakage gaps.

[0087] When the vertical anti-seepage frame is hoisted into the trench, the lower end of the vertical anti-seepage frame is combined and abutted against the anti-seepage blanket, and the top pressure arc piece 23 is extended into the gap between the inner frame body 10 and the outer frame body 20 through external equipment, so that the top pressure arc piece 23 abuts against the inclined surface of the wedge block 22, thereby increasing the distance between the inner frame body 10 and the outer frame body 20, so that the inner frame body 10 and the outer frame body 20 are combined with the compacted bentonite to ensure the subsequent anti-seepage effect.

[0088] In order to ensure the sealing of the joint position of the vertical anti-seepage frames, a joint unit is provided on both sides of the outer frame body 20 and the inner frame body 10, and the joint unit is used to achieve a sealed joint between adjacent vertical anti-seepage frames.

[0089] The combining unit is preferably a flexible structure with a certain degree of deformation ability to ensure the tight connection between the outer frame body 20 and the inner frame body 10 at both sides of the combining position, and adapt to the displacement of the vertical anti-seepage frame along the length direction of the groove, thereby avoiding leakage problems at the combining position of the vertical anti-seepage frame.

[0090] The combining unit includes a combining flexible sheet 50, which is arranged on both sides of the outer frame body 20 and the inner frame body 10. At least two groups of combining grooves 51 are provided on the combining flexible sheet 50. The sides of the outer frame body 20 and the inner frame body 10 are respectively clamped in the combining grooves 51. The combining flexible sheet 50 is provided with a second telescopic section 52, and the second telescopic section 52 is wavy. The combining flexible sheets 50 at both sides are respectively provided with engaging protrusions 53 and engaging grooves 54. The engaging protrusions 53 between adjacent vertical anti-seepage frames are clamped in the engaging grooves 54. Both sides of the GCL waterproof blanket 30 extend out of the outer frame body 20, so that a section of the GCL waterproof blanket 30 is left at the engaging position. When the engaging protrusion 53 is clamped in the engaging groove 54, the extended GCL waterproof blanket 30 is conducive to improving the airtightness.

[0091] In one embodiment, the GCL waterproof blanket 30 has a relatively long extension at both sides, which can adapt to the width change of the outer frame body 20 and the inner frame body 10 and prevent the GCL waterproof blanket 30 from being torn.

[0092] The combined flexible sheet 50 may be made of flexible corrosion-resistant rubber. A steel wire is embedded in the second telescopic section 52 on the combined flexible sheet 50, so that the second telescopic section 52 is spring-shaped. Under normal conditions, the second telescopic section 52 is shortened, so that the outer frame body 20 and the inner frame body 10 are in a closed state. When the distance between the outer frame body 20 and the inner frame body 10 increases, the second telescopic section 52 is extended, so that the combined flexible sheet 50 can adapt to the change in the distance between the outer frame body 20 and the inner frame body 10.

[0093] A third telescopic section 55 is extended on the outer side of the combined flexible sheet 50, and the third telescopic section 55 is arranged along the width direction of the outer frame body 20. The cross-section of the third telescopic section 55 is wavy, and two groups of the third telescopic sections 55 are arranged in parallel and at intervals. The third telescopic section 55 and one side of the combined flexible sheet 50 form a rectangular box-shaped structure, and the engaging protrusion 53 is arranged on one side of the third telescopic section 55 and is connected to the extended end of the third telescopic section 55 as a whole. The width adjustment unit includes an adjusting wedge block 57 arranged on the outer side of the third telescopic section 55, and the adjusting wedge block 57 is provided with an inclined surface. An adjusting frame 56 is provided on the adjusting wedge block 57, and the adjusting frame 56 abuts against the inclined surface of the adjusting wedge block 57 and links the two groups of frames to move away.

[0094] Specifically, the adjusting wedge block 57 is provided with an inclined surface which is narrow at the top and wide at the bottom. The adjusting frame 56 is a groove-shaped steel plate. When the vertical anti-seepage frame is installed in the groove, the adjusting frame 56 is squeezed into the upper end of the adjacent vertical anti-seepage frame by using equipment, so that the steel plates on both sides of the adjusting frame 56 abut against the inclined surface of the adjusting wedge block 57, thereby making the engaging protrusions 53 and the engaging grooves 54 of the combined flexible sheet 50 on both sides of the vertical anti-seepage frame combined as a whole, and the combined Figure 3 , so that the GCL waterproof blanket 30 is located between the fitting protrusion 53 and the fitting groove 54 to achieve the purpose of anti-seepage.

[0095] A method for constructing a vertical anti-seepage wall using the anti-seepage frame comprises the following steps:

[0096] Step 1: Use a trenching machine to trench the surface to be constructed, and use mud pumping equipment to protect the formed trench wall;

[0097] Step 2: Clean the mud in the trench to ensure that the bottom of the trench is clean and flat to prevent stones or protruding foreign objects from piercing the GCL waterproof blanket;

[0098] Step 3: Lay the GCL waterproof blanket 30 on the bottom of the trench, so that the GCL waterproof blanket 30 is laid flat on the bottom of the trench;

[0099] Step 4: Use the lifting equipment to lift the upper end of the vertical anti-seepage frame, lift the vertical anti-seepage frame into the trench, and arrange it neatly along the length direction of the trench so that the bottom end of the vertical anti-seepage frame is close to the GCL waterproof blanket 30;

[0100] Step 5: Fill the outer frame and inner frame of the vertical anti-seepage frame with anti-seepage soil between the trench wall and the trench wall, and compact the filled anti-seepage soil by extrusion equipment, so that the outer frame and inner frame of the vertical anti-seepage frame are combined with the anti-seepage soil into one;

[0101] Step six: Use equipment to adjust the width of the vertical anti-seepage frame so that the sides of the vertical anti-seepage frame are sealed together, and adjust the spacing between the inner frame and the outer frame of the vertical anti-seepage frame so that the inner frame and the outer frame are combined with the anti-seepage soil to form a stable vertical anti-seepage wall in the trench.
