Problems solved by technology

[0004] (1) The working space for welding construction around the 360-degree circumference of the dam-piercing pipe is not considered; the narrow working space makes it difficult to weld the side of the dam-piercing pipe close to the foundation cushion of the reservoir bottom, and the interface close to the foundation cushion of the reservoir bottom is often not welded firmly. In place, welding quality is difficult to guarantee
[0005] (2) The difference in shear force at the connection between the dam-piercing pipe and the leachate drainage main pipe at the bottom of the reservoir is not consid

Embodiment 1

[0037] a kind of like figure 1 The connection structure between the leachate guide and drain pipe of the solid waste treatment site and the dam piercing pipe shown in the present invention is that the liquid outlet of the leachate drain pipe 2 and the liquid inlet of the dam piercing pipe 3 are connected through a flexible connection. Docking; the top of the dam-piercing pipe 3 is covered with the anti-seepage film layer 5 of the slope of the solid waste treatment site; Both the anti-seepage film layer 5 and the anti-seepage film layer 4 at the bottom of the solid waste disposal site are hot-melt welded on the periphery of the dam-piercing pipe 3, and the area where the aforementioned hot-melt welding is located is also connected to the solid waste treatment site by at least one stainless steel hoop 6. The slope anti-seepage film layer 5 and the solid waste treatment plant bottom anti-seepage film layer 4 are tightly hooped on the outside of the dam-piercing pipe 3 .

Embodiment 2

[0044] a kind of like figure 2 , image 3 The connection structure between the leachate drainage pipe and the dam-piercing pipe of the solid waste disposal site of the present invention (this embodiment is a landfill) is shown, and the leachate drainage pipe 2 in this embodiment is the landfill reservoir The main leachate guide at the bottom mainly collects the landfill leachate produced in the solid waste treatment site, etc. The dam piercing pipe 3 in this embodiment is a connecting pipe connecting the leachate guide pipe 2 and the regulating tank 9, and its main The landfill leachate collected in the leachate drainage pipe 2 is exported to the regulating tank 9 outside the solid waste treatment site.

[0045] Such as figure 2 , image 3 As shown, the solid waste treatment site of this embodiment is laid with an anti-seepage film layer 4 at the bottom of the solid waste treatment site and an anti-seepage film layer 5 at the slope of the solid waste treatment site, and t...

Abstract

The invention discloses a connection structure for a percolate drainage pipe and a dam penetrating pipe of a solid waste disposal site and a construction method. According to the connection structure, the percolate drainage pipe and the dam penetrating pipe are in butt joint through a flexible connection manner; a side slope seepage-proof film layer and a bank bottom seepage-proof film layer of the solid waste disposal site cover the upper side and the lower side of the dam penetrating pipe; the seepage-proof film layers are hotly melted and welded at the periphery of the dam penetrating pipe, and a hotly-melted and welded region is used for tightly clamping the seepage-proof film layers on the outer side of the dam penetrating pipe by stainless steel hoop rings. The construction method comprises the following steps: firstly, utilizing a two-path monorail welding method, wherein a first path is used for hotly melting and welding the seepage-proof film layers on the dam penetrating pipe and a second path is used for covering a connector protective film on a first path of holt-melting and welding connector and fully welding one circle of a monorail; then, covering a flexible connection film on the holt-melting and welding connector of the dam penetrating pipe and hooping the two ends of the flexible connection film by the stainless steel hoop rings to complete construction. The connection structure and the construction method can guarantee the working stability of the percolate drainage pipe and the dam penetrating pipe, and the overhauling and maintenance can be conveniently carried out at a later period.

Description

technical field [0001] The invention belongs to the technical field of arrangement structure and construction of a solid waste treatment site, and in particular relates to a connection structure of a leachate guide pipe and a dam-piercing pipe and a construction method thereof. Background technique [0002] In recent years, in order to reduce the environmental pollution caused by municipal solid waste, cities above the county level have successively invested a large amount of funds in the construction of domestic waste sanitary landfills to replace the previous simple landfills. Among them, anti-seepage in the reservoir area, leachate collection and drainage system, and leachate treatment system are important components of the harmless municipal solid waste sanitary landfill, and the anti-seepage effect directly affects the harmless treatment effect of domestic solid waste. After a sampling survey, it was found that after more than 90% of the landfills were put into use, lea...
