Abstract
The present invention discloses a method for manufacturing a wide-size composite geomaterial, which is characterized in that the manufacturing process comprises the following steps: step a, a woven fabric and a non-woven cloth fabric are rolled; step b, the rolled woven fabric and non-woven cloth fabric are compounded into a compound bottom fabric by needle pricking operation; step c, the compound bottom fabric is rolled; step d, bentonite is laid; step e, the bentonite is uniformly treated; step f, the non-woven fabric and the compound bottom fabric laid with the bentonite are rolled; step g, the rolled non-woven fabric and the compound bottom fabric laid with the bentonite are compounded and shaped by needle pricking operation; step h, rolling operation is carried out; step i, a finished product is packaged. The present invention provides the method for manufacturing a wide-size composite geomaterial, which has the advantages of high safety factor, simple generating technology and low requirements on production devices in the whole producing process. The present invention is helpful for wide popularization so as to form large-scale bulk production. In addition, the purchasing cost of the raw materials is low, and the operating cost can be greatly reduced. The wide-size composite geomaterial has good using effect and the functions of effective water prevention and moisture resistance, and can be used in the fields of water conservancy, gardens, environmental protection engineering, urban constructing engineering, foundation engineering, etc.
Description
Technical field:
The present invention relates to the technical field of civil engineering. specifically a kind of wide cut composite earthwork material manufacturing method.
Background technology:
At present both at home and abroad in impervious material is made, traditional engineering mostly is the composite geo-membrane product of PE film, PVC film or geotechnological material and PE, PVC film greatly with impervious material, not only make cumbersome, must use the welding equipment of specialty could carry out operation at the construction field (site), and after the geomembrane welding, also to do special seal tightness test. could reach instructions for use, moreover, traditional antiseepage film is in case in construction or use, after being stabbed out by sharp object or damaging, that just can't reach desirable anti-seepage effect.
Summary of the invention
The object of the present invention is to provide a kind of wide cut composite earthwork material manufacturing method. with the swelling scholar clamp of high-quality made a kind of novel impervious material between two-layer geotechnological material, it can overcome some shortcomings of the prior art.
To achieve these goals, technical scheme of the present invention is: a kind of wide cut composite earthwork material manufacturing method, it is characterized in that: its manufacture process is the woven cloth of a., nonwoven distributing volume, and b. acupuncture is combined into compound base fabric, and c. is compound, and base fabric send volume, d. bentonite is laid, e. bentonite is even, and f. nonwoven, the bentonitic compound base fabric of laying send volume, g. acupuncture composite molding, h. batch the i. finished product packing.
The invention provides a kind of wide cut composite earthwork material manufacturing method, safety coefficient height in the whole process of production, generation technology is simple. and less demanding to production equipment, help extensively popularizing, to form large-scale mass production, moreover. purchasing of raw materials cost is lower, can reduce recurrent costs greatly, this wide cut composite earthwork material section result of use is better, can play effective water proof dampproof effect, can in every field such as water conservancy, gardens, environment-friendly engineering, urban construction project, foundation engineering, use.
The present invention has following characteristics:
1, can be good from water-retaining property: have bigger dilatancy during owing to bentonite and water reaction, it can repair the defective that causes when self being stranded transportation or construction. and have extremely strong self-healing ability, and can repair 2 millimeters with interior concrete surface crackle.
2, have permanent water resistance:, aging or corrosion phenomenon can not take place because of swelling soil series natural inorganic material. so water resistance is lasting.
3, compliance with environmental protection requirements: bentonite is natural material, and is harmless, has splendid environmental-protecting performance, and this material weatherproof, also the brittle failure phenomenon can not take place under the condition of cold.
4, the easy construction duration is short: compare with other waterproof material, the construction of GCL is simple relatively, do not need special equipment that material is heated and paste. only need nail, packing ring and bentonite material, and do not need special inspection after the construction, yet maintenance easily of discovery waterproof defective on the one yet.
Description of drawings
Accompanying drawing is a manufacturing flow chart of the present invention.
The specific embodiment:
Manufacture process of the present invention is: the woven cloth of a., nonwoven distributing volume, and b. acupuncture is combined into compound base fabric, and c. is compound, and base fabric send volume, d. bentonite is laid, and the e. bentonite is even, and f. nonwoven, the bentonitic compound base fabric of laying send volume, g. acupuncture composite molding, h. batches, the i. finished product packing.The speed of described woven cloth and nonwoven distributing volume is 0.5 meter/minute～5 meters/minute, woven cloth and nonwoven acupuncture speed are 1～5 meter/minute, punch frequency is 150～800 times/minute, it is 0.5～5 meter/minute that compound base fabric send the speed of volume, bentonite laying speed is 200～6000 Grams Per Minutes, it is 1～5 meter/minute that the compound base fabric of nonwoven, laying profit soil send volume speed, and nonwoven, the bentonitic compound base fabric acupuncture speed of laying are 1～5 meter/minute, and punch frequency is 150～600 times/minute.
Embodiment 1: with woven cloth, nonwoven send volume with 2 meters/minute speed respectively. through the fabric guide roll needing machine of making a gift to someone, acupuncture speed is 2 meters/minute. punch frequency is 300 times/minute, make it be connected into the compound base fabric that intensity and percentage elongation all adhere to specification, when compound base fabric send when being involved in dusting device with 2 meters/minute, the dusting roller begins the speed dusting with 400 gram/minute, laterally send into the material propellers by regulating, bentonite is sent the whole horizontal fabric width of completely compound base fabric, along with moving forward of compound base fabric, evenly roller evenly spreads out the powdery of the ore on the compound base fabric or graininess and nutrition soil, respectively with 2 meters/minute speed with nonwoven, lay bentonitic compound base fabric and send volume, send into needing machine through fabric guide roll. acupuncture speed is 2 meters/minute kinds, punch frequency is 350 times/minute, both acupunctures are connected into the composite earthwork material. batch finished product packing.
Embodiment 2: with woven cloth, nonwoven send volume with 3 meters/minute speed respectively. through the fabric guide roll needing machine of making a gift to someone, acupuncture speed is 3 meters/minute. punch frequency is 700 times/minute, make it be connected into the compound base fabric that intensity and percentage elongation all adhere to specification, when compound base fabric send when being involved in dusting device with 3 meters/minute, the dusting roller begins the speed dusting with 800 gram/minute, laterally send into the material propellers by regulating, bentonite is sent the whole horizontal fabric width of completely compound base fabric, along with moving forward of compound base fabric, evenly roller is with the powdery of the ore on the compound base fabric or graininess and nutrition ± evenly spread out, respectively with 3 meters/minute speed with nonwoven, lay bentonitic compound base fabric and send volume, send into needing machine through fabric guide roll. acupuncture speed is 3 meters/minute kinds, punch frequency is 700 times/minute, both acupunctures are connected into the composite earthwork material. batch finished product packing.
