Abstract
The invention discloses the laying method of a kind of refuse landfill HDPE geomembrane, realized by below step: (1) is cut out and overlapped, and is cut out by HDPE geomembrane, overlaps around reservoir area and reservoir area；(2) sweat soldering, overlap joint upper slice and bottom sheet between blast compressed air, form compressed air channel, weld seam is formed at described compressed air channel the right and left, two panels HDPE geomembrane is carried out hot melt, docks rapidly after arriving temperature, and weld in described commissure；(3) checking and repair, the HDPE geomembrane after completing sweat soldering checks, in place of checking the damage of the HDPE geomembrane laid, more than more than the 10% of every HDPE geomembrane width in place of damage, then this section is sheared, again lays.Use in the middle of blasts compressed-air actuated method, be cut out tearing after laying completes excess stock time, do not have weld seam tear, reduce repair cost.
Description
Technical field
The present invention relates to a kind of method laying HDPE geomembrane in refuse landfill, belong to ring
Protect technical field.
Background technology
Refuse landfill reservoir area is typically to build to be had on acclive landform, and reservoir area is the most external
The terrain slope in portion is that nature is downward, includes seepage control system and guide system, and seepage control system is
Refer to that the substrate soil upper berth around this most internal and reservoir area, reservoir area sets impervious material, prevent rubbish from oozing
Filtrate permeates the ground secondary pollution；Guide system refers to by laying two-layer pipeline, guide respectively
Substrate soil is because building refuse landfill reservoir area and the subsoil water that gathers and percolate.
HDPE is high density polyethylene (HDPE), has high anti-seepage effect, and HDPE geomembrane is the most gradually
The more seepage control system for refuse landfill.After existing HDPE geomembrane overlaps,
Easily rupture at weld when finally shearing, cause the wasting of resources, and make for a long time
With rear, Seepage easily occur, construction cost is high, and follow-up maintenance cost is high.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides a kind of refuse landfill HDPE geomembrane
Laying method, weld consolidation not easy to leak, smooth welded seam, reduce later maintenance cost.
The present invention is to be realized by following technical scheme:
The laying method of a kind of refuse landfill HDPE geomembrane, is real by below step
Existing:
(1) cut out and overlap, HDPE geomembrane is cut out, around reservoir area and reservoir area
Overlap；
(2) sweat soldering, overlap joint upper slice and bottom sheet between blast compressed air, formed
Compressed air channel, forms weld seam at described compressed air channel the right and left, by two panels HDPE
Geomembrane carries out hot melt, docks rapidly, and weld in described commissure after arriving temperature
Connect；
(3) checking and repair, the HDPE geomembrane after completing sweat soldering checks,
In place of checking the damage of the HDPE geomembrane laid, more than every HDPE geomembrane in place of damage
More than the 10% of width, then shear this section, again lay.
Hot melting temperature in described step (2) is 100-150 DEG C.
Welding temperature in described step (2) is 450-480 DEG C.
The invention have the benefit that
1, weld of the present invention is smooth, not easy to leak, is difficult to tear；
2, frequency of maintenance of the present invention reduces, and maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is that refuse landfill HDPE geomembrane of the present invention lays welding schematic diagram
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
1, cut out and overlap, HDPE geomembrane is cut out, entering around reservoir area and reservoir area
Row overlap joint；
2, sweat soldering, such as Fig. 1, is that refuse landfill HDPE geomembrane of the present invention lays weldering
Connect schematic diagram, HDPE geomembrane upper slice 61 and bottom sheet 62 to overlap, overlap joint upper slice
And between bottom sheet, blast compressed air, form compressed air channel 17, in described compressed air
Passage the right and left forms weld seam 15 and 16, and two panels HDPE geomembrane carries out hot melt, heat
Melting temperatur is maintained at 100-150 DEG C, docks rapidly after arriving temperature, and at described weld seam
Welding at 15 and 16, welding temperature is 450-480 DEG C；
3, checking and repair, the HDPE geomembrane after completing sweat soldering checks, inspection
In place of the damage of the HDPE geomembrane that inspection of the beds at night sets, more than every HDPE geomembrane width in place of damage
More than the 10% of degree, then shear this section, again lay.
Claims (1)
1. the laying method of a refuse landfill HDPE geomembrane, it is characterised in that be real by below step
Existing: (1) is cut out and is overlapped, and is cut out by HDPE geomembrane, overlaps around reservoir area and reservoir area；
(2) sweat soldering, overlap joint upper slice and bottom sheet between blast compressed air, form compressed air channel,
Described compressed air channel the right and left forms weld seam, and two panels HDPE geomembrane carries out hot melt, arrives temperature
Dock rapidly after degree, and weld in described commissure；(3) check and repair, complete to sweat soldering
HDPE geomembrane after one-tenth checks, in place of checking the damage of the HDPE geomembrane laid, damages
This section more than more than the 10% of every HDPE geomembrane width, is then sheared, is again laid by part；
Hot melting temperature in described step (2) is 100-150 DEG C, and the welding temperature in described step (2) is 450-480 DEG C.
