Description

Dark continuously shop geomembrane device

Technical field:

The utility model relates to a kind of dark continuously shop geomembrane device, is used for granular soil layer seepage control project, as the antiseepage treatment project in fields such as water conservancy dykes and dams, old soot and urban construction.

Background technology:

The geomembrane that uses in the antiseepage of water conservancy dykes and dams, old soot and urban construction etc. is handled is 0.2-2mm thick polyethylene, igelite antiseepage film and composite geo-membrane (polyethylene film, polychloroethylene film and polyester-type nonwoven or the non-woven fabric compounded body of polypropylene type) at present.Commonly used is polyvinyl chloride (PVC) geomembrane and polyvinyl chloride composite geo-membrane, polyethylene (PE) geomembrane and polyethylene composite geo-membrane.

These geomembranes all are the waterproof rolls of plant produced, therefore in the waterproof, seepage control engineering construction, must connect every volume joint.The common at present method that adopts mutual overlap joint or the interface gluing is bonded together.Directly the geomembrane of overlap joint is difficult to be adjacent to densification at interface, seeps water easily and mortar, and anti-seepage effect is bad; The gluing bonding method need hang behind the joint gluing, thereby speed of application is slow, particularly in humidity than under the overall situation, adhesive effect is undesirable.Two kinds of jointing methods all can butt joint antiseepage quality cause totally unfavorable influence, thereby influence the antiseepage quality and the working life of whole engineering.

Present construction equipment still can not be realized breaking ground continuously and spreading film, and work efficiency is lower; And the shop film degree of depth can only reach in underground 10 meters, can not satisfy the actual needs in above-mentioned engineering field.

Summary of the invention:

The purpose of this utility model is to provide a kind of dark continuously shop geomembrane device, it is the sinking of can breaking ground voluntarily, cut the device of native grooving, deslagging, shop film and waste residue backfill groove more continuously, the joint of geomembrane twines tight in junction block and carry out grouting reinforcement in junction block, make the connection between the geomembrane fastening firm, its shop film degree of depth can reach 40 meters.

The technical solution of the utility model is achieved in that continuously dark shop geomembrane device, wherein on bottom girder, be connected with pylon, an end that is connected the wire rope on the pulley of pylon is fixed on the soil-cutter, the other end is connected with hydraulical impact mechanism and is fixed on the winch, and bottom girder is provided with opening so that promote and transfer soil-cutter; Be fixed with the return slag pipe on the next door of soil-cutter, and link to each other, on soil-cutter, be connected with feed pipe and link to each other, the geomembrane case is set and casing is connected on the bottom girder in return slag pipe one side with supply-water pump with gravel pump; The junction, top of rolling up geomembrane in the end and the back one of last volume geomembrane is the geomembrane piecing devices fixedly; Have groove on the body of geomembrane piecing devices.

Good effect of the present utility model is: it is for breaking ground sinking voluntarily, cut the device of native grooving, deslagging, shop film and waste residue backfill groove more continuously, the termination of geomembrane is twined in junction block closely and carry out grouting reinforcement in junction block, makes the connection between the geomembrane fastening firm; Its shop film degree of depth can reach 40 meters.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

1, the end of last volume geomembrane; 2, geomembrane piecing devices; 3, the top of back one volume geomembrane; 4, geomembrane case; 5, return slag pipe; 6, soil-cutter; 7, pylon; 8, supply-water pump; 9, gravel pump; 10, hydraulic impact mechanism; 11, bottom girder and walking mechanism; 12, winch;

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described, as shown in Figure 1, dark continuously shop geomembrane device, wherein on bottom girder 11, be connected with pylon 7, an end that is connected the wire rope on the pulley of pylon 7 is fixed on the soil-cutter 6, the other end is connected with hydraulical impact mechanism 10 and is fixed on the winch 12, has the opening of lifting and decline soil-cutter 6 on the bottom girder 11; Be fixed with return slag pipe 5 on the next door of soil-cutter 6, the return slag pipe links to each other with gravel pump 9, is connected with feed pipe and links to each other with supply-water pump 8 on soil-cutter 6, geomembrane case 4 is set and casing is connected on the bottom girder 11 in return slag pipe 5 one sides; Be connected and fixed at the end 1 of last volume geomembrane and the top 3 usefulness geomembrane piecing devices 2 of back one volume geomembrane; Have groove on the body of geomembrane piecing devices 2.

The film construction of antiseepage shop comprises two processes: sinking pore-forming and fluting shop film.At first adopt and impact and water jetting sinking pore-forming, drive wire rope with winch then and soil-cutter 6 is transferred in place, under the effect of hydraulical impact mechanism 10, wire rope drives soil-cutter 6 and up and down reciprocatingly cuts native grooving, the degree of depth of soil-cutter 6 flutings can determine according to circumstances that its degree of depth can reach 40 meters; At this moment the sand particle of Qie Xiaing is extracted into the face of land by return slag pipe 5 from bottom land by gravel pump 9 with mud, and has spread with its backfill in the groove of film.Walking mechanism 11 moves forward with the whole device of corresponding speed drive, realizes cutting continuously soil, deslagging grooving; Geomembrane case 4 is being emitted geomembrane when moving; When geomembrane connected, geomembrane piecing devices 2 were put in the termination 1,3 of front and back two volume geomembranes, and it is special steel pipe, two terminations of film are stretched in the body groove, rotate body two films be wrapped on the outside wall surface of pipe tightly, two films are close to together, block water by.Then to carrying out slip casting in managing, make casing pack have cementing properties and impervious slurry material, the slurry material fixed after, the termination of two films can be cemented in the pipe, thus these geomembrane piecing devices 2 have make two film terminations tightly wrap and make the termination the pipe in by fixed double seal effect.Native grooving, deslagging, shop film and waste residue backfill groove have been realized cutting continuously.
