Abstract
The invention discloses a method for paving non-woven geotechnical cloths in a refuse landfill. The method comprises the following steps: (1) clipping: clipping the non-woven geotechnical cloths to be proper sizes according to the terrain of a paving field; (2) thermally bonding and paving: splicing the two non-woven geotechnical cloths needed to be thermally bonded on the scene, and thermally bonding lapped parts; and (3) inspecting paving: inspecting the damaged parts of the non-woven geotechnical cloths, clipping the sections when the damaged parts are more than the width of the each clipped non-woven geotechnical cloth by 10%, and repaving. The method for paving non-woven geotechnical cloths in the refuse landfill is used for preventing landfill leachate to permeate soil, thermal bonding parts are smooth and unlikely to be torn, and maintenance cost can be reduced.
Description
Technical field
The present invention relates to a kind of in refuse landfill reservoir area and surrounding area lay the method for non-woven geotextile, belong to environmental technology field.
Background technology
Refuse landfill reservoir area is normally built on the acclive landform of tool, the terrain slope of reservoir area body exterior is that nature is downward, include seepage control system and guide system, seepage control system refer in the body of reservoir area and reservoir area around substrate soil upper berth establish impervious material, prevent the percolate secondary pollution that permeates the ground; Guide system refers to by laying two-layer pipeline, guide substrate soil gathers because build refuse landfill reservoir area respectively underground water and percolate.
Existing seepage control system is to lay geomembrane on substrate soil, but need on substrate soil, first lay one deck non-woven geotextile before laying geomembrane.Non-woven geotextile has good antiseepage, filtration and isolation effect, is the first barrier of refuse landfill reservoir area first protecting group subsoil earth.
The method that existing non-woven geotextile adopts on-the-spot overlap joint to paste is laid, this method location for paste there will be projection, out-of-flatness, solid not, the situation such as easily tear, above-mentioned situation causes the non-woven geotextile that existing laying completes need to often carry out maintenance overhaul, is occurring that breakage need to repair, wasting manpower and material resources, has improved operation cost.
Summary of the invention
The invention provides a kind of laying method of refuse landfill non-woven geotextile, heat bonding place is smooth, solid, is difficult for tearing, and reduces frequency of maintenance, greatly cost-saving.
The present invention realizes by following technical scheme:
A laying method for refuse landfill non-woven geotextile is to realize by following step:
(1) cut out, non-woven geotextile is cut out to suitable size according to laying on-the-spot landform;
(2) heat bonding is laid, and two non-woven geotextiles that need to carry out heat bonding carry out scene overlap joint, in lap-joint, carry out heat bonding;
(3) check and lay, check the damage part of the non-woven geotextile of laying, damage part and be greater than 10% of the every non-woven geotextile width of cutting out, this section is sheared, again lay.
In described step (2), heat bonding temperature is 100-150 ℃.
In described step (2), the lap width of two non-woven geotextiles of heat bonding is 20-30mm.
Beneficial effect of the present invention is:
1, heat bonding place stable connection of the present invention, smooth, firmly.
2, heat bonding place of the present invention is difficult for tearing, and not cracky reduces maintenance cost.
The specific embodiment
Below the present invention is illustrated.
The present invention realizes by following method:
1, cut out, first check that whether landform, the substrate soil of refuse landfill reservoir area and reservoir area substrate soil is around smooth, solid, have foreign matter appearance place, remove.Non-woven geotextile is carried out to cutting out of appropriate size according to reservoir area landform, after cutting out end, overlap, two of overlap joint lay on substrate soil, overlap joint position is between 20-30mm, due to before not carrying out heat bonding, the non-woven geotextile having overlapped need to be fixed, and the fixing anchor type that adopts, by the non-woven geotextile tension of whole reservoir area overlap joint.
2, heat bonding is laid, and heat bonding need to be heated two non-woven geotextiles of overlap joint, and wherein a kind of embodiment is to adopt the heat gun of 3000W power to heat welding, and lap-joint guarantees smooth welded seam.
3, check and lay, check the damage part of the non-woven geotextile of laying, damage part and be greater than 10% of the every non-woven geotextile width of cutting out, this section is sheared, again lay.
Claims (3)
1. a laying method for refuse landfill non-woven geotextile, it is characterized in that realizing by following step:
(1) cut out, non-woven geotextile is cut out to suitable size according to laying on-the-spot landform;
(2) heat bonding is laid, and two non-woven geotextiles that need to carry out heat bonding carry out scene overlap joint, in lap-joint, carry out heat bonding;
(3) check and lay, check the damage part of the non-woven geotextile of laying, damage part and be greater than 10% of the every non-woven geotextile width of cutting out, this section is sheared, again lay.
2. the laying method of refuse landfill non-woven geotextile as claimed in claim 1, is characterized in that in described step (2), heat bonding temperature is 100-150 ℃.
3. the laying method of refuse landfill non-woven geotextile as claimed in claim 1, is characterized in that the lap width of two non-woven geotextiles of heat bonding in described step (2) is 20-30mm.
