Abstract
The utility model discloses a tubular product of a composite reinforced concrete lining modified polyvinyl chloride drainage pipe. The tubular product comprises a pipe body which is a concrete pipe body or a reinforced concrete pipe body; wherein, a modified polyvinyl chloride layer which is fixed by clinging to the inner wall of the tubular product is lined in the interior of the pipe body and is poured into a whole with the pipe body. The drainage pipe provided by the utility model has not only the advantages of the reinforced concrete pipes but also all the advantages of plastic pipes and better meets the engineering requirements.
Description
Technical field
The utility model relates to a kind of municipal drainage engineering waste pipe, and a kind of Composite Steel reinforced concrete liner modified polyvinyl chloride waste pipe especially is provided.
Background technique
At present, municipal drainage engineering tubing commonly used has two kinds, and the one, concrete reinforced pipe, the 2nd, plastic tube.Conventional steel reinforced concrete pipe stiffness is big, and cost is low, and interface shape is various, applied range, but inner wall coarse, and surface friction drag is big, and decay resistance is relatively poor; And plastic tube inner wall smooth, the coefficient of friction resistance are little, corrosion-resistant, good seal performance, long service life, but rigidity is lower, and the cost height.
The model utility content
The purpose of this utility model is to improve the defective of prior art, and a kind of advantage that had both had concrete reinforced pipe is provided, and whole advantages of plastic tube are arranged again, can better satisfy the Composite Steel reinforced concrete liner modified polyvinyl chloride waste pipe of engineering demand.
The tubing of the Composite Steel reinforced concrete liner modified polyvinyl chloride waste pipe that the utility model provides comprises a body, it is concrete or reinforced concrete body, liner modified polyvinyl chloride (PVC) layer on the inwall of described body, described modified polyvinyl chloride layer is close to pipe material inner wall and is fixed, and waters with described body and builds up integral body.
In order to make that the modified polyvinyl chloride layer of liner is securely fixed on the described body more on the inboard wall of tube body, the side that contacts with described body of described modified polyvinyl chloride layer is provided with fin, and it is embedded in described body.
Described fin is preferably the fin of end size greater than the root size.This fin extends at the axial direction of body, and this fin for example is T font shape on the tubing section.
The utility model reinforced concrete liner modified polyvinyl chloride waste pipe is applicable to that tubing nominal diameter scope is 150～3000mm.
Because it is body that the utility model adopts traditional concrete reinforced pipe, so its construction process is identical with traditional concrete reinforced pipe with application area.And the utility model and water contact position be PVC, can reach and well close the water effect, and can prolong the working life of tubing.
Description of drawings
The cross-sectional configuration schematic representation of the Composite Steel reinforced concrete liner modified polyvinyl chloride waste pipe that Fig. 1 provides for the utility model;
The axial broken section structural representation of the Composite Steel reinforced concrete liner modified polyvinyl chloride waste pipe that Fig. 2 provides for the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
The Composite Steel reinforced concrete liner modified polyvinyl chloride waste pipe that provides for the utility model as shown in Figure 1, 2, it is made up of reinforced concrete body 1 and liner modified polyvinyl chloride layer 2 two-part.Adopt the production technology of traditional concrete reinforced pipe to produce, the modified polyvinyl chloride layer is close to pipe material inner wall during production, waters with concrete reinforced pipe and builds up integral body.The reinforced concrete body mainly bears the external pressure load in actual applications, and it is better to reach to close the water effect that liner modified polyvinyl chloride layer mainly acts on.
Modified polyvinyl chloride rare (PVC) is the existing well known materials of the industry.
In order to make that the modified polyvinyl chloride layer of liner is securely fixed on the described body more on the inboard wall of tube body, the side that contacts with body 1 of modified polyvinyl chloride layer 2 is provided with fin, and it is embedded in body 1.
Fin is preferably the fin of end size greater than the root size.This fin extends at the axial direction of body, and this fin for example is T font shape on the tubing section, as shown in Figure 2.
The reinforced concrete liner modified polyvinyl chloride waste pipe that the utility model adopts is to make like this: roll welding Framework Of Steel Reinforcement at first, the modified polyvinyl chloride layer that processes is fixed together with the pipe internal mold, after putting into Framework Of Steel Reinforcement between pipe internal mold and the pipe external mold, get togather template, adopt the concrete reinforced pipe moulding process, to enter in the mould that has Framework Of Steel Reinforcement by the concrete casting that design mixture proportion is mixed system, stop maintenance through quiet, after reaching prescribed strength, enter demoulding program, the warehouse-in that is up to the standards is equipped with pin.
The waste pipe that provides in the two basic model utilitys part that combines adopts the spigot and socket type combining structure, and sealing compound 3 sealing orifices are set on the mouth of pipe that two pipes join.
The utility model reinforced concrete liner modified polyvinyl chloride waste pipe is applicable to that tubing nominal diameter scope is 150～3000mm.
