Abstract
The invention relates to a solid-wall cement pipe with dual characteristics of a plastic pipe and a cement pipe and a manufacturing method thereof. The solid-wall cement pipe comprises a cement pipe, wherein the inner wall of the cement pipe is made of plastic, and the outer wall of the cement pipe is made of cement. The solid-wall cement pipe has the advantages that: compared with similar plastic pipes, a PE (polyethylene) material is saved by 80 percent; the connection is convenient, the investment of connection equipment is available in 1000yuan (RMB), the connection of one solid-wall cement pipe can be finished just for 17 minutes, while similar solid-wall pipe connection equipment needs to be invested for 500,000yuan (RMB), and the excavating capacity of each similar solid-wall pipe in an installation site is 3 times of that of the plastic pipe; the connection is reliable thoroughly without leakage; and the cost is low, which is 30 percent of the cost of the plastic pipe with same performance, and the service life and the corrosion resistance are more than 20 times of those of the cement pipe.
Description
Technical field
The present invention relates to a kind of plastic tube characteristic that both had, have the real wall cement pipe and the making method of cement pipe characteristic again, belong to water supply and sewerage pipeline and make the field.
Background technique
The steel band reinforced pipe adopts steel plate as internal layer on structural design, improves the ring stiffness of supplying drainage with this.Its deficiency: the one, be subjected to inner steel product stress to influence unstable product quality; The 2nd, the steel corrosion that gets rusty easily.
The plastics winding reinforcing pipe on structural design, adopts the PE hollow cylinder to strengthen, and improves draining pipe ring stiffness with this.Its deficiency: the product cost height, be difficult to bear, be 50-80 times of price of portland cement pipe, market is difficult to accept.
The cement steel waste pipe, on structural design, this type of pipe can be accomplished very big ring stiffness, and cost is enough low.Its water foot part: it is the corrosion of anti-underground sewage not, and the leakage problems especially severe.
Double-wall corrugated pipe, on structural design, this tubing is limited by mould, and product only can be accomplished 2 meters (diameters), and the ring stiffness is low, the cost height.Equipment investment is big.
Summary of the invention
Purpose of design: avoid the deficiency in the background technique, design a kind of plastic tube characteristic that both had, have the real wall cement pipe and the making method of cement pipe characteristic again.
Design proposal: in order to realize above-mentioned purpose of design.The cement pipe inwall is a plastic wall, and the cement pipe outer wall is the design of cement wall, is major technique feature of the present invention.The purpose of doing like this is: plastic tube wall has good anti-corrosion, it can prevent the corrosion of underground sewage effectively, and do not deposit leakage problems, and the cement steel waste pipe, on structural design, can accomplish very big ring stiffness, and cost is enough low, the two combination, both solve the deficiency that background technique exists, realized purpose of design of the present invention again.
Technological scheme 1: a kind of real wall cement pipe, it comprises cement pipe, and described cement pipe inwall is a plastic wall, and the cement pipe outer wall is the cement wall.
Technological scheme 2: a kind of making method of large-scale real wall cement pipe, the real wall cement steel cage that at first will weave is inserted in the shaping die, penetrate the plastic tube that makes in the shaping die then and plastic tube around be spacing with reinforcement cage and cooperate, at last with concrete placement on plastic tube and reinforcement cage, plastic tube and reinforcement cage are fixed as one forming inwall is that plastic tube wall, outer wall are the reinforced concrete wall.
The present invention compares with background technique, and the one, save PE material 80% than similar plastic tube; The 2nd, the connecting part makes, 1000 yuan of connection device investments just can, can connect one in 17 minutes, and similar real wall plastic tube connection device invests 500,000, solid wall pipe mounting site excavation volume is 3 times of sizes that this plastic tube excavates volume; The 3rd, connect reliably 100% ne-leakage; The 4th, low-cost, be 30% of same performance plastic tube cost, working life, corrosion resistance was that cement pipe is more than 20 times.

Fig. 1 is the structural representation of real wall cement pipe.
Fig. 2 is the local structure for amplifying schematic representation of Fig. 1.
Fig. 3 is Fig. 1 docking structure schematic representation.
Embodiment
Embodiment 1: with reference to accompanying drawing 1 and 3.A kind of real wall cement pipe, it comprises cement pipe, and described cement pipe inwall is a plastic tube wall 1, and the cement pipe outer wall is a cement wall 2.Described cement wall 2 is made of reinforcing bar 3 and concrete.Described plastic tube wall 1 is real wall plastic tube wall or structural plastic tube wall.
Embodiment 2: on embodiment 1 basis, a kind of making method of large-scale real wall cement pipe, the real wall cement steel cage that at first will weave is inserted in the shaping die, penetrate the plastic tube that makes in the shaping die then and plastic tube around be spacing with reinforcement cage and cooperate, at last with concrete placement on plastic tube and reinforcement cage, plastic tube and reinforcement cage are fixed as one forming inwall is that plastic tube wall, outer wall are the reinforced concrete wall.It is innermost layer pure plastic pipe (containing real wall and structured wall popes), skin is the ordinary steel bar cement pipe, the two is fixed as one by cast, in conjunction with epipodium stiffness, low-cost and the highly corrosion resistant of plastic tube and the non-leakage characteristics of cement pipe, the shortcoming that the two is overcome is separately selected its advantages.
What need understand is: though the foregoing description is to the mentality of designing of the present invention detailed text description of contrasting; but these text descriptions; just the simple text of mentality of designing of the present invention is described; rather than to the restriction of mentality of designing of the present invention; any combination, increase or modification that does not exceed mentality of designing of the present invention all falls within the scope of protection of the present invention.
