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.
