Description

Technical Field

[0001] This application relates to the technical field of anti-leakage treatment for garbage pits, and in particular to a main anti-leakage structure for a garbage pit and the garbage pit itself. Background Technology

[0002] Currently, the main structure of garbage pits for corrosion prevention and leakage prevention is mostly a frame shear wall structure, which is made of C40P8 impermeable concrete. The inner side of the main wall of the garbage pit is coated with epoxy glass flake coating and cement-based penetrating crystalline coating. The epoxy glass flake coating is used for corrosion prevention, and the cement-based penetrating crystalline coating is used for leakage prevention.

[0003] However, during the construction of the main body of the waste disposal site, cracks are prone to appear in the concrete shear walls, and during operation, the epoxy glass flake coating + cement-based penetrating crystalline coating is easily damaged by impacts from the waste crane. This can easily lead to structural cracks and damage to the anti-corrosion and anti-seepage layers, resulting in leakage problems during operation and negatively impacting the air quality of the surrounding production workshops. Utility Model Content

[0004] To ensure the structural integrity of the waste disposal site and improve its resistance to seepage, corrosion, and impact, this application proposes a new seepage-proof, corrosion-proof, and impact-resistant structural design. This design replaces the conventional frame-shear wall structure used for the main body of the waste disposal site.

[0005] Specifically, this application provides a main leak-proof structural design for a waste pit, including:

[0006] The embedded part includes an anchoring claw and an exposed surface, wherein the anchoring claw is located inside the main body of the waste pool, and the exposed surface protrudes from the main body of the waste pool;

[0007] HDPE membrane is disposed on the main surface of the waste pit, and the HDPE membrane is welded and fixed to the exposed surface of the embedded part;

[0008] A protective layer, wherein the protective layer is a concrete layer containing iron filings, the concrete layer being disposed on the surface of the HDPE membrane; and

[0009] Tool bolt assembly connects the main body of the waste pit, the HDPE membrane, and the protective layer.

[0010] As a preferred embodiment, the tool bolt assembly includes:

[0011] A first tool bolt, one end of which is disposed within the main body of the waste pool;

[0012] A plug component is disposed within the protective layer, and the other end of the first tool bolt is disposed within the plug component;

[0013] A second tool bolt, one end of which is disposed within the plug member, and the other end of which is located outside the protective layer; and

[0014] The kit is mounted on the first tool bolt and is located within the protective layer. The kit is welded and fixed to the HDPE membrane.

[0015] As a preferred embodiment, the plug component is a tapered plug component with internal threads, and the long bottom surface of the tapered plug component is located on the surface of the protective layer.

[0016] As a preferred embodiment, the horizontal and vertical spacing of the tool bolt assembly is 300-600mm; the length of the first tool bolt is greater than the length of the second tool bolt; the other end of the first tool bolt is provided with a first thread that engages with the thread of the tapered plug component; one end of the second tool bolt is provided with a second thread that engages with the thread of the tapered plug component, and the other end of the second tool bolt is provided with a third thread.

[0017] As a preferred embodiment, the exposed surface is welded to the HDPE film using an extrusion welding gun; the HDPE film is welded to the kit using an extrusion welding gun.

[0018] As a preferred embodiment, the embedded part is an E-type lock embedded part, which includes three anchoring claws and an exposed surface; multiple E-type lock embedded parts are arranged circumferentially along the main body of the garbage pit in the horizontal direction, and the vertical arrangement spacing is 500-1000mm.

[0019] As a preferred embodiment, the concrete layer includes a steel mesh made of φ6mm ordinary hot-rolled round steel arranged in a single layer in two directions at @150×150mm, and the steel mesh is connected to the tool bolt assembly.

[0020] In addition, this application also provides a garbage pit, including a garbage pit body and a main body anti-leakage structure of the garbage pit as described above disposed on the garbage pit body.

[0021] Compared with the prior art, this application has the following beneficial effects:

[0022] The structural impermeable and corrosion-resistant layer of this application uses a high-density polyethylene (HDPE) membrane, while the impact-resistant protective layer of the HDPE membrane uses cast-in-place iron filings and fine aggregate concrete. This fully utilizes the advantages of HDPE membrane, such as its high impermeability coefficient, good chemical stability, good aging resistance, and environmental friendliness and non-toxicity. The iron filings-containing concrete is used for the protective layer, which fully utilizes the advantages of iron filings, such as increasing the strength and wear resistance of the concrete, improving its load-bearing capacity and durability, and its low cost.

[0023] The combined system of the main wall self-waterproof structure of the garbage pit, HDPE membrane anti-seepage and anti-corrosion layer, and iron filings concrete anti-collision protection layer in this application plays a positive role in improving the anti-seepage and anti-corrosion capabilities of the garbage pit and resisting the impact of garbage crane collisions on the anti-seepage and anti-corrosion layers of the garbage pit wall.

[0035] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] In some embodiments, such as Figure 1 As shown, this application provides a garbage pit and a main anti-leakage structure 1 of the garbage pit. Specifically, the main anti-leakage structure of the garbage pit includes an embedded part 11, an HDPE membrane 12, a protective layer 13, and a tool bolt assembly 14.

[0037] Specifically, such as Figure 2As shown, in some embodiments, the embedded part can be an E-type lock embedded part, including three anchoring claws 111 and an exposed surface 112; multiple E-type lock embedded parts are arranged circumferentially along the horizontal direction of the main body of the waste pool, and the vertical arrangement spacing is 500-1000mm. The anchoring claws 111 are located inside the main body 10 of the waste pool, and the exposed surface 112 protrudes from the main body 10 of the waste pool. Specifically, the E-type lock embedded part can be made of HDPE material, the width of the exposed surface 112 is 100mm, and the length of the anchoring claws 111 can be 50mm. The E-type lock embedded part is used to fix and connect the HDPE membrane 12 to the main body 10 of the waste pool, and the E-type lock embedded part is pre-embedded during the construction of the main body of the waste pool. The installation requirement of the E-type lock embedded part is that it must be closely attached to the inner surface of the cast-in-place concrete pouring formwork, which is beneficial to improving the welding area and welding quality between the HDPE membrane 12 and the E-type lock embedded part.

[0038] HDPE membrane 12 is disposed on the surface of the main body 10 of the waste pit, and the HDPE membrane 12 is welded and fixed to the exposed surface 112 of the embedded part 11. Specifically, the exposed surface 112 and the HDPE membrane 12 can be welded using an extrusion welding gun. The thickness of the HDPE membrane 12 can be 0.5mm, and double-seam hot-melt welding is preferred at the joints. The HDPE membrane 12 is positioned at the part that directly contacts the waste, i.e., below the elevation of the waste inlet platform.

[0039] The protective layer 13 is a concrete layer containing iron filings, which is disposed on the surface of the HDPE membrane 12. Specifically, the concrete layer may include a steel mesh made of φ6mm ordinary hot-rolled round steel arranged in a single layer at @150×150mm, and the steel mesh is connected to the tool bolt assembly. The thickness of the concrete layer containing iron filings can be 100mm. The cast-in-place fine aggregate concrete containing iron filings with an embedded single-layer bidirectional steel mesh serves as a crack-resistant structure for the protective layer. Round steel is preferred, as it facilitates uniform distribution of iron filings during the pouring of the protective layer 13. Using cast-in-place fine aggregate concrete containing iron filings helps protect the HDPE membrane 12, allowing it to maintain its integrity over a long period. Adding iron filings to the concrete helps improve its strength and wear resistance.

[0040] The tool bolt assembly 14 connects the main body 10 of the waste pool, the HDPE membrane 12, and the protective layer 13.

[0041] In some embodiments, such as Figure 3 and Figure 4 As shown, as a preferred embodiment, the tool bolt assembly 14 includes a first tool bolt 141, a plug member 142, a second tool bolt 143, and a kit 144.

[0042] Specifically, one end of the first tool bolt 141 is disposed inside the main body 10 of the garbage pit; the other end of the first tool bolt 141 is disposed inside the plug member 142.

[0043] The plug component 142 is disposed within the protective layer 13.

[0044] One end of the second tool bolt 143 is disposed inside the plug member 142, and the other end of the second tool bolt 143 is located outside the protective layer 13.

[0045] The kit 144 is mounted on the first tool bolt 141 and is located within the protective layer 13. The kit 144 is welded and fixed to the HDPE film 12. Specifically, the HDPE film 12 and the kit 144 can be welded using an extrusion welding gun.

[0046] In some embodiments, the plug member 142 is a tapered plug member with internal threads, and the long bottom surface of the tapered plug member is located on the surface of the protective layer 13.

[0047] In some embodiments, the horizontal and vertical spacing of the tool bolt assemblies is 300-600mm; the length of the first tool bolt 141 is greater than the length of the second tool bolt 143; the other end of the first tool bolt 141 is provided with a first thread that engages with the thread of the tapered plug member; one end of the second tool bolt 143 is provided with a second thread that engages with the thread of the tapered plug member, and the other end of the second tool bolt 143 is provided with a third thread.

[0048] Specifically, the tool bolt assembly 14 of this application may be a two-stage pull-bar tool bolt composed of a first tool bolt 141 and a second tool bolt 143, the kit 144 is an HDPE heat shrink sleeve, and the plug member 142 is a tapered plug member with internal threads.

[0049] The first tool bolt 141 and the second tool bolt 143 are preferably made of HRB400 steel bars with a diameter ≥12mm. The spacing can be calculated based on the lateral pressure borne by the formwork during the single pouring height of the protective layer, with a horizontal and vertical spacing of generally 300-600mm. The first tool bolt 141 is a 280mm long anchor rod for the protective layer; the second tool bolt 143 is 220mm long and is used as a temporary component for formwork reinforcement during the protective layer construction stage. The first tool bolt 141 and the second tool bolt 143 are connected by a tapered plug component with internal threads. The first thread is 30mm long and is used to connect with the tapered plug component with internal threads. The remaining 250mm of the first tool bolt 141 is unthreaded, of which 200mm is used for anchoring to the main body 10 of the waste pit, 20mm is used for bonding the HDPE heat shrink sleeve, and 30mm is used for bonding to the protective layer 13. The second tool bolt 143 is 220mm long and has threads at both ends. One end is 30mm long and is used to connect with the conical plug component with internal threads. The other end is 40mm long and is used to tighten the nut to fix the template to resist the lateral pressure on the concrete pouring template during the pouring of the protective layer concrete. The middle 150mm length has no threads and is used to pass through the template and its back rib reinforcement system, such as timber and scaffolding pipes. The HDPE heat shrink sleeve is 20mm long and is welded to the HDPE membrane 12 using an extrusion welding gun. It is used for seepage prevention at the connection node between the first tool bolt 141 and the HDPE membrane 12. The conical plug component with internal threads is 40mm long. During installation, the end with the larger diameter should face outwards for easy removal after the template of the protective layer 13 is removed. The conical groove is sealed with a micro-expansion, easily compacted, and sufficiently strong material.

[0050] In this application, the protective layer 13 is preferably connected to the main body 10 of the waste pit using a steel mesh and anchor bolts. The steel mesh is made of φ6mm ordinary hot-rolled round steel, which helps to form a single reinforced concrete structure for the protective layer. The anchor bolts are two-stage tie rods. The first tie rod 141 is used for anchoring to the main body 10 of the waste pit, which facilitates a reliable connection between the protective layer 13 and the main body 10 of the waste pit. It can be embedded in advance during the construction of the pit or after the formwork is removed, which improves the operability of embedding the first tie rod 141 into the main body of the waste pit. The second tie rod 143 is used to resist the lateral pressure borne by the cast-in-place concrete protective layer formwork. The steel mesh and the first tie rod 141 are preferably connected by binding, which is beneficial for the protection of the finished HDPE membrane 12. The HDPE membrane 12 is preferably connected to the first tie rod 141 by inserting an HDPE heat shrink sleeve at a local position of the first tie rod 141. The HDPE membrane 12 and the heat shrink sleeve are welded using an extrusion welding gun, which is beneficial for the seepage prevention effect at the connection node between the first tie rod 141 and the HDPE membrane.
