Description
Technical field
The present invention relates to landfill yard HDPE film and lay field, especially the sanction of deep camber side slope HDPE film connects method.
Background technology
Southern area landfill yard mostly is mountain valley-type, it is built by the mountain, reservoir area is built usually Harmony with site and is utilized existing chevron through simply showing clearly, repaiies slope and form, the waste burying built maintains the topography and geomorphology of original massif substantially, storehouse basin presents the taper of wide narrow base suitable for reading, just what platform slope has built for anchoring impervious material.Be illustrated in figure 1 the floor map of typical Valley Type Landfill Site 100, the geomorphologic characteristics replaced due to former massif ridge col as seen from the figure and make anchored platform present cranky looks, occur the curve side slope that multiple curvature differs.The laying of landfill slope HDPE film should be parallel to grade of side slope line, ensures that HDPE film is perpendicular to leg wire of slope as far as possible.In curve side slope section, curvature difference due to upper and lower anchored platform can cause line length poor, paved surface is fan-shaped, therefore just there will be when carrying out monoblock HDPE film and laying and lays angle (laying the angle of line and grade line), affect the construction quality of antiseepage film.Occur should revising in time when laying angle, make laying line be parallel to grade line as far as possible, this is an important content of landfill site seepage prevention film construction.
The sanction of curved batter HDPE film connects mode directly affects speed of application and spillage of material, closely related with construction cost.In the big-and-middle-sized Valley Type Landfill Site with Slope with multi-step, often there is more deep camber curved batter (encircled as in Fig. 1), the correcting mode that HDPE film lays angle is just particularly evident on the impact of construction cost.Therefore, in the laying construction process of HDPE, in the construction of especially multistage deep camber side slope, choose a kind of mode that connects of reasonably cutting out just extremely important for quickening speed of application, saving material.
At present, it is " overall cut-off method " that the routine that correction HDPE film laying angle adopts cuts mode.Namely, as shown in Figure 2, lay HDPE film 300 between upper mounting plate anchor line 201 and lower platform anchor line 202 after, produce between the longitudinal edge of HDPE film 300 and grade line 101 and lay angle theta, HDPE film 300 is cut along the cutting line 303 being parallel to grade line 101 bottom HDPE film 300 longitudinal edge, thus cut out and cut diaphragm 302, and retain the longitudinal edges parallel of diaphragm 301 in grade line 101, thus eliminate and lay angle theta.The method has the following disadvantages:
(1) during Valley Type Landfill Site Seepage, limit by orographic condition, the carrying of impervious material often cannot use machinery and have to rely on inefficient a dead lift, costly.Revise and lay angle and cut the residue diaphragm got off and will migrate out stockyard outside the venue, add extra transhipment operation and construction cost.
(2) in irregular curve landform, cut the reason that the diaphragm that gets off differs due to diaphragm length and diaphragm angle theta, be difficult to match the consistent recycling position of specification, be applied to the position compared with small-sized after can only being repaiied by further sanction, this will waste portion of material; And if it is little to cut the diaphragm specification of getting off, recycling will be difficult to and become discarded leftover pieces, and causing all material to waste.
(3) when recycling cuts diaphragm, first will carry out scene to the position occurring laying angle and measure, then select the immediate diaphragm of specification to stockyard, the scene that is finally transported to is carried out sanction and is repaiied installation recycling.Construction sequence is complicated, effort of taking a lot of work, and increases construction cost.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of effective utilization and cuts the sanction that the HDPE film that gets off eliminates the deep camber side slope HDPE film laying angle and connect method.
In order to solve the problems of the technologies described above, the sanction that the invention provides a kind of deep camber side slope HDPE film connects method, to be laid in side slope and the grade line of longitudinal edge and side slope exists the HDPE film laying angle, to comprise the following steps for cutting:
A, determine mid point by the longitudinal edge of HDPE film and be parallel to the mid point cutting line of grade line;
B, mid point cutting line are decided to be actual cutting line after HDPE center membrane direction translational offsets distance, and described actual cutting line is through the longitudinal edge of described HDPE film;
C, cut HDPE film along actual cutting line, cut out and cut diaphragm, residue diaphragm is retained in side slope, and residue the cut longitudinal edge one of diaphragm after cutting is parallel to grade line, and the longitudinal edge one that do not cut remaining diaphragm still exists with grade line and lays angle;
D, the described diaphragm that cuts is rotated 180 °, make to cut diaphragm do not cut that longitudinal edge two is overlapped on residue diaphragm do not cut on longitudinal edge one, make to cut simultaneously diaphragm cut that longitudinal edge two aligns residue diaphragm cut longitudinal edge one, make that the transverse edge two cutting diaphragm aligns residue diaphragm with transverse edge one that is that do not cut longitudinal edge one and be connected simultaneously;
E, welding cut diaphragm cut longitudinal edge two and residue diaphragm cut overlapping part overlap of longitudinal edge one, residue diaphragm and cut the complete longitudinal edge parallel with grade line of the rear formation of diaphragm welding, thus elimination laying angle.
Preferably, described offset distance is 5cm.
Preferably, described HDPE film is laid in the side slope between parallel upper mounting plate anchor line and lower platform anchor line.
Preferably, it is characterized in that: in step e, welded by double track hot-melt welding machine during welding.
Compared with prior art, first the present invention finds out the mid point cutting line through HDPE film longitudinal edge mid point, then mid point cutting line is obtained actual cutting line to center translation, cut out along actual cutting line and cut diaphragm, and remain diaphragm and form area at the diagonal position cutting diaphragm and be less than and cut diaphragm and the vee similar to cutting diaphragm, to cut after diaphragm rotates 180 ° splices at this breach, make to cut diaphragm do not cut that longitudinal edge two is overlapped on residue diaphragm do not cut on longitudinal edge one, make to cut simultaneously diaphragm cut longitudinal edge two and transverse edge two respectively with residue diaphragm cut longitudinal edge one and transverse edge one aligns.After cutting diaphragm welding, the cropped diaphragm of the residue original vee of diaphragm is completely supplementary, and forms the complete longitudinal edge parallel with grade line after remaining diaphragm and cutting diaphragm welding, thus eliminates laying angle.The present invention does not have HDPE film waste material to produce, and improves HDPE film utilization rate; Meanwhile, owing to being the correction realizing laying angle by the cutting of this block HDPE film self, constructing fast and convenient, avoid original construction cost and a dead lift cost.
