Description
Technical field
The utility model relates to a kind of structure of waterproof roll, and the structure of waterproof roll for especially a kind of novel tunnel, belongs to waterproofing materials technical field.
Background technology
Composite geo-membrane refers to the waterproof roll being combined into one by one of polyethylene (PE), polyvinyl chloride (PVC), haloflex (CPE), several antiseepage film of ethylene-propylene copolymer (EPC) and polyester or polypropylene non-woven fabric.If directly composite geo-membrane is laid on concrete, waterproof effect is poor, once be punctured easy to leak.The existing waterproof roll for constructing tunnel, generally formed by nonwoven and antiseepage film, that face that antiseepage film contacts with nonwoven is provided with connection strap, connection strap two ends are fixed in antiseepage film, then pass successively the middle part of nonwoven, connection strap with one end of suspender belt, finally pass again nonwoven (suspender belt middle part is arranged between polyester non-woven fabric and polyethylene antiseepage film and with connection strap and is connected, and suspender belt two ends are respectively through nonwoven).In use, directly waterproof roll is laid on to the construction surface in tunnel, and the two ends of suspender belt are connected on constructing tunnel face.The waterproof roll of this structure, complex structure, first needs connection strap two ends to be fixed in antiseepage film, then also need a large amount of manpowers that suspender belt is passed to connection strap, nonwoven and antiseepage film are linked together, not only consume material, also waste time and energy, and increase cost of production.
Utility model content
The purpose of this utility model is for for above-mentioned the deficiencies in the prior art, provides one to save production cost, novel tunnel waterproof roll simple in structure, time saving and energy saving.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel tunnel waterproof roll, comprise polyester non-woven fabric, polyethylene antiseepage film, suspender belt, suspender belt middle part is arranged between polyester non-woven fabric and polyethylene antiseepage film, suspender belt two ends are respectively through polyester non-woven fabric, it is characterized in that, the ultrasonic bonding that described polyethylene antiseepage film, polyester non-woven fabric are greater than 15MPa by intensity links together; Described waterproof roll is provided with the solder joint of ultrasonic bonding, and solder joint is dot matrix and distributes, and the distance between adjacent two rows' solder joint is 15-35mm, and the distance between the solder joint of adjacent two row is 15-25mm, and solder joint is star, quadrangle, ellipse.
Between described polyethylene antiseepage film and polyester non-woven fabric, be provided with hot melt adhesive layer.
On described waterproof roll, the solder joint of ultrasonic bonding is concentrated the middle part that is distributed in waterproof roll.
The thickness of described polyester non-woven fabric is 0.15-0.35cm.
The thickness of described polyethylene antiseepage film is 0.35-0.55cm.
The length of described suspender belt is 25-65cm, and the width of suspender belt is 0.8-2.0cm.
The utility model adopts the complex method of ultrasonic bonding that polyethylene antiseepage film and polyester non-woven fabric are combined with each other, ultrasonic bonding is to utilize dither ripple to be delivered to the body surface of two need welding, in pressurization in the situation that, make the mutual friction of two body surface phases and form the fusion between molecular layer.Ultrasonic bonding speed is fast, and weld strength is high, good airproof performance, can make polyester non-woven fabric and polyethylene antiseepage film firmly link together.
The utility model replaces traditional welding/technique for sticking, without connection strap is set, with low cost, cleanliness without any pollution and can not damage workpiece; Welding process is stable, and all welding parameters all can be carried out tracing and monitoring by software systems, once find that fault is easy to get rid of and safeguard.PUR be arranged so that between polyethylene antiseepage film and polyester non-woven fabric be connected more firm.When use, waterproof roll is laid on to the working face in tunnel, and suspender belt two ends are fastened on constructing tunnel face.Distance between adjacent two rows' solder joint is 15-35mm, distance between the solder joint of adjacent two row is 15-25mm, it is stressed more equal that the pad that dot matrix distributes makes to be laid on the waterproof roll of tunnel top, and pad is mainly concentrated the middle part that is distributed in waterproof roll, tunnel is generally arch, waterproof roll is laid and is suspended on the arch face in tunnel, its stress point mainly concentrates on middle part, and both sides pad too much, it is the tie point that the both sides of polyester non-woven fabric and polyethylene antiseepage film need not be too many, more time saving and energy saving like this, save cost.The thickness of polyester non-woven fabric is 0.15-0.35cm, the thickness of polyethylene antiseepage film is 0.35-0.55cm, and the length of suspender belt is 25-65cm, and the width of suspender belt is 0.8-2.0cm, the result of use that these data make waterproof roll more, is through a large amount of experiments and the achievement of research repeatedly.
The utility model is used for constructing tunnel, easy construction, and good water-proof effect, simple in structure, time saving and energy saving, save cost of production, there is the wide market space.
