Abstract
The utility model relates to a prestress plastic corrugated pipe, which includes a pipe body (1) with corrugation. The corrugated pipe is characterized in that the pipe body (1) is provide with monocyclic ring corrugation with isometry inner concave and outer convex; a small monocyclic ring with 1-2mm height of a corrugated arris (3) is arranged just between two isometry big ring corrugation; wherein, the big ring pipe corrugated arris (2) is 4-5mm in height, 3-5mm in width, and 2-3mm in thickness, and the minimum bending radius of the pipe is 0.9-1.5m. Because the corrugated arris is arranged in monocyclic ring method, the plastic corrugated pipe has strong rigidity and high bearing strength, can not be tore by a tamper, and has no leakage under the load and within the bending range. The plastic corrugated pipe is mainly applied to the municipal department, water conservancy department, post and telecommunication department and the like, and can be used as the drainage pipeline, and can be used for installation of concrete projects such as highway overpasses, viaducts, railroad bridges and the like.
Description
Technical field
The invention belongs to building material technical field, relate to a kind of plastic tube, a kind of prestressing force YXBG plastic film capicitor of saying so more specifically with annular ripple outer wall construction.
Background technique
Plastic film capicitor is mainly used in municipal administration, water conservancy, and departments such as post and telecommunications can be used as the draining blow-off line, the installation of concrete workses such as expressway overpass, viaduct, railroad bridge.To have with the high density polyethylene (HDPE) be main raw material to the plastic film capicitor of Chu Xianing in the market, extrude by inside and outside respectively, and disposal molding, inwall is level and smooth, and outer wall is trapezoidal corrugated bellows; The plastic film capicitor that also has the spiral thread structure; The bellows of prestressing force metal bellows and other products of rubber and plastic.Its main deficiency of the bellows of these unlike materials is: the plastic film capicitor crest of spiral thread structure is little, and wave space is little, and area of contact is little, and bonding strength is relatively poor.Disposal molding, its shortcoming of the plastic film capicitor of inner wall smooth is that it and concrete binding are bad, the inner wall smooth prestressed tendon is corroded easily.
The YXBG prestressed plastic corrugated pipe is a kind of tubing with annular ripple outer wall construction.The high density polyethylene (HDPE) (be regenerated plastics) of main raw material for reclaiming forms the tubing with superior function by machining.The utilization of regenerated plastics when reducing the cost of product, can also utilize refuse again, to the improvement of environment with develop a circular economy positive meaning is all arranged.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art with not enough, a kind of novel prestressed plastic corrugated pipe is provided, it comprises the body (1) of being with ripple, it is characterized in that body (1) is the single annular ripple of equidistant indent evagination, the little monocycle of a height 1-2mm ripple rib (3) is arranged in equidistant two annular corrugated greatly (2) middle; Wherein big endless tube ripple rib (2) highly is 4-5mm, big endless tube ripple rib (2) width 3-5mm, thickness of pipe wall 2-3mm, tubing minimum bending radius 0.9-1.5 rice.
Big endless tube ripple rib of the present invention (2) is 30mm with the spacing of little ring ripple rib (3), and little endless tube ripple rib (3) is 30mm with the spacing of big endless tube ripple rib (2).
The performance characteristics of YXBG plastic film capicitor of the present invention:
1.YXBG plastic film capicitor is that corrosivity is far superior to metal, can effectively protect and answer muscle not corroded in advance;
2. the aging quality resistance at internals reaches 50 years; YXBG plastic film capicitor and concrete adhesive property are good simultaneously, because its ripple height height, area of contact is big, the bonding strength height.
3. tubing is thick is 2-3mm, becomes single annular to arrange that rigidity is big, and the bearing strength height is difficult for being poked by vibrating spear, and ne-leakage under the load is designed to minimum bending radius 0.9-1.5 rice (about 10-15 times internal diameter or major axis) ne-leakage under bending range.
The coefficientoffriction in 4 ducts=0.01-0.14 K=0.0008-0.0015/m; Good insulating, non-conductive, can prevent stray current corrosion, improved the feasibility of prestressed tendon electronic monitoring.
YXBG plastic film capicitor of the present utility model is to adopt extruder to extrude once extruding plasticizing and moulding in molding machine in mould continuously, and there is not the phenomenon of threading off and leaking in plastic ripple.By hot briquetting device again tubing is drawn simultaneously, hauling speed is that 0.3-3m/min has improved its tensile stress.The YXBG plastic film capicitor is as the draining blow-off line, concrete workses such as expressway overpass, viaduct, railroad bridge, structure and properties in when construction according to it, can use with corresponding ground tackle connection in the aqueduct corner of construction, be embedded in underground or bridge water delivery place, cover with cement above and reinforce.Thereby problems such as plastic film capicitor and concrete bonding, crooked, resistance to pressure have well been solved.
The good effect that plastic film capicitor of the present invention is compared with prior art had is:
(1) plastic film capicitor of the present utility model has characteristics corrosion-resistant, ageing-resistant, good with concrete cementability, resistance to pressure.At first, the structure difference, body is designed to the single annular ripple of equidistant indent evagination, and the little monocycle of a height 1-2mm ripple rib (3) is arranged in equidistant two big annular corrugated middles simultaneously; Wherein big endless tube ripple rib (2) highly is 4-5mm, tube wave line rib (2) width 3-5mm, thickness of pipe wall 2-3mm, tubing minimum bending radius 0.9-1.5 rice.More help the water mud drum and cover tubing.Solved and concrete bonding, crooked, resistance to pressure problem; Better with concrete cementability, pipe performance is more excellent, and cost of production is low.
(2) adopt prescriptions such as reclaiming plastics, pure regenerated plastics, preservative, antiageing agent, binder, pigment, make that the chemical property of tubing is more stable.
(3) Xian Jin manufacturing mechanism makes the performance of tubing, quality be better than other products.This product is mainly used in municipal administration, water conservancy, and departments such as post and telecommunications can be used as the draining blow-off line, in the concrete workses such as expressway overpass, viaduct, railroad bridge.
