[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work, any modifications, equivalent replacements, improvements, etc., should be included in the protection scope of the utility model.

[0027] like Figures 1 to 9 As shown, this embodiment discloses a rigid landfill structure for hazardous waste disposal, including a landfill shell 4, wherein 9 landfill shells 4 are provided and all 9 landfill shells 4 are supported and positioned by a frame assembly;

[0028] The frame assembly includes 16 columns 1, which are usually steel structures. The 16 columns 1 are distributed in a matrix shape. A fixing plate 2 is provided at the bottom end of the column 1 and is fixedly connected to the ground through fixing screw holes provided on the fixing plate 2. A reinforcement plate 3 is provided between adjacent columns 1. The two ends of the reinforcement plate 3 are bolted to two adjacent columns 1 through reinforcement screw holes 102 provided on the side walls of the column 1. During installation, the reinforcement plate 3 can be installed on one side of the column 1, or on both sides of the column 1.

[0029] The reinforcement plate can improve the stability of the connection structure between multiple columns, avoid the situation where the position of a certain column is tilted or offset, resulting in unstable placement of the landfill shell connected to the column, and ensure the stability of the installation structure of the entire rigid landfill.

[0030] The column 1 is a rectangular column structure, and support grooves 101 are provided at the four end corners of the upper end of the column 1, and the four support grooves 101 are symmetrically arranged in pairs; the support grooves 101 are in the shape of a rectangular column, and the height direction of the support grooves 101 is consistent with the height direction of the column 1. The top of the support groove 101 passes through the top end wall of the column 1, and the height of the support groove 101 is consistent with the height of the landfill shell 4; the height between the bottom end of the support groove 101 and the ground at the bottom end of the column 1 is 1 to 1.5 meters, which can not only ensure the stability of the rigid landfill, but also allow people to bend down and enter the visual inspection walking channel 6 for inspection work.

[0031] Among the 16 columns 1, a landfill shell 4 is disposed between every four adjacent columns 1 arranged in a square shape, and the landfill shell 4 is supported and positioned by the support grooves 101 on the four columns 1;

[0032] The landfill shell 4 is in the shape of a rectangular column shell with an open top, which is usually a concrete structure or a reinforced concrete mixed structure. The installation area of ​​the landfill shell 4 is formed between the support grooves 101 corresponding to the four adjacent columns 1 arranged in a square. The outer diameter of the installation area is adapted to the outer diameter of the landfill shell 4. The four peripheral edges and corners of the landfill shell 4 are respectively located in the support grooves 101 of the four columns 1 and can slide to the bottom end of the support grooves 101 along the height direction of the column 1, so as to support the bottom end corner position of the landfill shell 4 through the bottom end face of the support groove 101; when the landfill shell 4 is connected to the frame assembly, the top end face of the support groove 101 is flush with the top end face of the landfill shell 4. After the landfill shell 4 is installed, its end corner position is carried on the bottom end face of the support grooves 101 of the four columns 1, and the landfill shell 4 is in a suspended state. There is a visual inspection walking channel 6 between the bottom end face of the landfill shell 4 and the ground, which allows people to bend and walk, so that people can monitor and check the leakage condition of the landfill shell 4.

[0033] The design of the sliding connection structure between the landfill shell and the supporting groove improves the assembly efficiency of the rigid landfill and facilitates the repair and maintenance of the landfill shell in the future.

[0034] The top end of the landfill shell 4 is covered with a top cover 5, which is in the shape of a quadrangular pyramid. A lifting ring 502 is provided at the center of the top end of the top cover 5 for convenient lifting operations. The outer diameter of the top cover 5 is consistent with the outer diameter of the top end of the landfill shell 4; a limiting convex ring 501 is integrally formed at the bottom end of the top cover 5, and the outer diameter of the limiting convex ring 501 is adapted to the inner diameter of the top end of the landfill shell 4; when the top end of the landfill shell 4 is connected to the top cover 5, the limiting convex ring 501 is embedded in the inner side of the top end of the landfill shell 4, and the outer edge of the top cover 5 is flush with the outer edge of the top end of the landfill shell 4.

[0035] The nine landfill shells 4 are distributed in a matrix shape between the 16 columns 1; when the landfill shell 4 is connected to the column 1, since four supporting grooves 101 are set on the column 1, the top of the column forms a cross axis shape, and each side of the cross axis is located between the end corners of two adjacent landfill shells 4. The side lengths of two adjacent cross axes and the end walls of the adjacent landfill shells 4 together form a water flow gap 7, which can be used for rainwater drainage operations.

[0036] After the rigid landfill is assembled, garbage, waste, etc. are loaded into the landfill shell, and then the top cover is closed on the top of the landfill shell, which can block rainwater and prevent rainwater from entering the landfill shell and causing more leakage of liquid in the cavity of the landfill shell; at the same time, when rainwater falls on the top cover, it will directly flow along the inclined surface of the top cover to the water flow gap outside the edge of the landfill shell or the outside of the edge of the rigid landfill, and will not remain on the top cover, thus avoiding the long-term retention of rainwater and leakage to affect the landfill, further improving the use effect of the rigid landfill.

[0037] The utility model adopts a design in which a supporting groove is arranged at the upper end of the column and the four bottom end corners of the landfill shell are supported by the four supporting grooves, so that after the rigid landfill is assembled, the landfill shell will be supported by the columns to form a suspended structure, and there are only a plurality of columns between the bottom end of the landfill shell and the ground, and a visual inspection walking channel will be formed between adjacent columns. People can regularly patrol in the visual inspection walking channel to check whether there is leakage at the bottom end of the landfill shell, so as to judge whether there is leakage defect in the landfill shell; the visual inspection walking channel facilitates people's daily monitoring of the rigid landfill, so that leakage of the landfill shell can be discovered in time, and the situation that the leakage flows into the ground for a long time and pollutes the groundwater occurs; and when a leakage is found in a landfill shell, the landfill shell can be separately lifted from the frame assembly by lifting equipment for repair or replacement, so that leakage treatment and maintenance operations of the rigid landfill are realized conveniently and quickly, and the use effect of the rigid landfill is effectively improved;

[0038] On the other hand, when assembling the rigid landfill in the utility model, it is only necessary to fix the columns on the ground, and then use the lifting equipment to embed the landfill shell from the top of the four columns into the supporting grooves at the relative positions of the four columns, and slide longitudinally along the columns, so that the bottom ends of the four supporting grooves finally support the landfill shell; the outer peripheral edges of the landfill shell are supported and positioned by the supporting grooves of the four columns, so that a stable connection support structure is formed between the frame assembly and the landfill shell, ensuring that the garbage and waste landfill operations of the rigid landfill are not affected; at the same time, the entire assembly operation is convenient and fast, which effectively improves the assembly rate of the rigid landfill and further improves the use effect of the rigid landfill.
