Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, the structure of the present invention includes a pool 1 , a wall 2 , a bottom plate 12 , a geotextile 3 , an HDPE anti-seepage membrane 4 , an anchoring bead 5 and an anchoring ditch 6 . The anchoring ditch 6 is arranged outside the pool 1 and has a rectangular cross-section. Its depth is close to the bottom width, and its depth is about 1 / 4 to 1 / 3 of the depth of the pool 1 . The geotextile 3 and the HDPE anti-seepage membrane 4 are laminated and laid on the bottom plate 12 and the wall 2 of the pool 1 as a whole. The anchoring layer 5 is used to fix the geotextile 3 and the HDPE anti-seepage membrane 4 on the wall 2 of the pool 1 . The anchor layer 5 is arranged around the pool 1 .

[0017] Look figure 2 The anchoring bead 5 includes an expansion bolt 8 driven into the wall 2 through the geotextile 3 ...

Abstract

The invention discloses a seepage prevention method and structure for a waste percolate collecting pool. According to the method, an HDPE seepage prevention film (4) and geotechnical cloth (3) are combined, and the geotechnical cloth (3) is laid between the HDPE seepage prevention film (4) and the inner wall of the pool (1); at least one anchoring press strip (5) surrounds the inner side wall of the pool (1) by one circle, and the HDPE seepage prevention film (4) and the geotechnical cloth (3) are pressed on the inner side wall of the pool (1) tightly. The geotechnical cloth (3) and the HDPE seepage prevention film (4) are adopted to form a composite seepage prevention system, the weight of the HDPE film and the weight of the geotechnical cloth are divided into two parts through the anchoring press strip, and the too large anchoring force born by an anchoring groove and the too large tensile stress of the HDPE film are reduced.

Description

technical field [0001] The invention relates to a film-laying anti-seepage method and structure of a vertical wall concrete pool for collecting waste leachate, belonging to the technical fields of chemical industry and municipal administration. Background technique [0002] Due to the limitation of terrain and geological conditions, the pools for collecting Class II general industrial waste or landfill leachate often need to be excavated and built into reinforced concrete structures, and the concrete walls are vertical (or the slope of the walls is very steep). In order to make the pool To reach a certain storage capacity, the pool wall is often high (greater than 10m). Class II general industrial waste or landfill leachate is often highly polluting and requires anti-seepage treatment for the pool. If the anti-seepage HDPE membrane is directly laid on the concrete wall of the pool, it is only done through the anchoring ditch. For anchoring, the anchoring force of the anchor...
