With the stricter and stricter environmental protection requirements of China, the hazardous waste disposal standard is continuously improved, and the rigid landfill is gradually the mainstream. Rigid landfills dispose of hazardous waste more safely and controllably than flexible landfills, so that intensive research into rigid landfills is necessary. The liner structure of the anti-seepage system of the rigid landfill is mainly composed of HDPE films and has the function of preventing the leakage of dangerous waste percolate from causing environmental pollution. The anchoring of the seepage-proofing system is a necessary engineering measure in the construction of the seepage-proofing system of the rigid landfill, effectively ensures that the HDPE film is stable and firm, and is closely attached to the wall of the rigid landfill pool. The commonly used anchor is fixed by a common hexagon nut expansion bolt.
However, the HDPE film is anchored by using the common hexagon nut expansion bolt, and the protruding nut and bolt of the HDPE film may damage the impermeable layer of the HDPE film in the later dangerous waste landfill process, so as to cause leachate leakage. Therefore, the anchoring of the HDPE film in the middle of the tank wall of the rigid landfill becomes a technical difficulty of the anti-seepage system engineering of the rigid landfill.
The utility model is provided based on the technical problems, and the anti-seepage structure anchoring related by the utility model can well solve the engineering problem of anchoring of an anti-seepage system of a rigid landfill.

The anti-seepage membrane on the pool wall is anchored by adopting a stainless steel pressing strip and an inner hexagonal flat-head expansion bolt, a hole with a corresponding size is drilled on the concrete pool wall through an electric drill, the inner hexagonal flat-head expansion bolt is arranged in the hole, and the HDPE anti-seepage membrane can be tightly anchored on the pool wall by screwing a nut. The chloroprene rubber plays a role in protecting the HDPE impermeable membrane. And a 50 cm-wide HDPE film is covered outside the stainless steel pressing strip, and the upper end and the lower end of the stainless steel pressing strip are connected and sealed with the main anti-seepage film on the tank wall by hot-melt extrusion welding. The structure has simple form, reliable quality and good anti-seepage effect.
Next, an impermeable structural anchoring according to an embodiment of the present invention is explained with reference to fig. 1 and 2.

In particular, the barrier anchoring provided by the present invention can be applied, for example, in the context of HDPE films in the middle of the tank walls of a rigid landfill for hazardous waste. The anchoring of the anti-seepage structure of the HDPE film can comprise a reinforced concrete landfill pool body, an HDPE film anti-seepage layer, chloroprene rubber, a stainless steel pressing strip, a hexagonal flat head expansion bolt and an anchoring-position HDPE film covering layer, wherein the anchoring-position HDPE film covering layer and the HDPE film anti-seepage layer are welded and fixed by adopting hot melting extrusion welding.
In some embodiments, the bolt anchors the impermeable layer to the landfill cell body through the gasket and the bead.
In some embodiments, the bolt is a hex head expansion bolt. Ordinary hexagon nut expansion bolts are used in conventional designs. Adopt ordinary hexagon nut expansion bolts anchor HDPE membrane, protruding nut and bolt can pierce through the HDPE membrane, cause the HDPE membrane to damage easily at the dangerous refuse landfill in-process of later stage, cause the filtration liquid seepage. The biggest difference between the anchoring of the inner hexagonal flat-head expansion bolt and the common hexagonal nut expansion bolt is that the exposed structure of the bolt is different, the exposed end of the inner hexagonal flat-head expansion bolt is a flat-head inner hexagonal head, the common hexagonal nut expansion bolt is exposed with longer bolts and nuts, and the raised bolts and nuts are easy to cause damage such as puncture and the like on an impermeable membrane.
In some embodiments, the cover layer covers the gasket, the bead, and the bolt.

The HDPE membrane covering layer at the anchoring part is used for protecting the anchoring structure, and meanwhile, the covering layer is welded on the main anti-seepage HDPE membrane by adopting extrusion welding, so that the anchoring part is sealed, and the seepage of percolate is prevented.
The design aims to consider that the vertical height of a rigid landfill is generally higher, the HDPE impermeable membrane can be torn due to self weight, and in addition, the HDPE membrane cannot be effectively attached to the pool wall. Through such design, can effectively prolong rigid landfill HDPE prevention of seepage membrane's life, can also effectively laminate HDPE membrane and pool wall in addition.
The assembly steps of the anti-seepage structure anchoring provided by the utility model are as follows: sequentially paving the HDPE film impermeable layers on the reinforced concrete landfill tank body; further, fixedly anchoring the HDPE membrane impermeable layer on the reinforced concrete landfill pool body through an inner hexagonal flat-head expansion bolt through a stainless steel pressing strip; further, the anchoring part HDPE film covering layer covers the chloroprene rubber, the stainless steel pressing strip and the inner hexagonal flat-head expansion bolt; and finally, fixedly connecting the HDPE film covering layer at the anchoring part with the HDPE film impermeable layer in a sealing manner by adopting hot-melt extrusion welding.
The anchoring mode of the HDPE film in the middle of the tank wall of the rigid landfill site is specifically realized by firstly paving an HDPE film impermeable layer 2 on a tank body 1 of the reinforced concrete landfill tank, then drilling a hole in the HDPE film impermeable layer 2, anchoring the HDPE film impermeable layer 2 on the reinforced concrete landfill tank body 1 by adopting an inner hexagonal flat-head expansion bolt 5 to penetrate through a chloroprene rubber gasket 3 and a stainless steel pressing strip 4, and finally covering the anchoring part by using an HDPE film 6 and connecting and fixing the HDPE film impermeable layer 2 by adopting hot-melt extrusion welding 7.
