Because the tensile strength and the elastic modulus of the steel wire are huge, and the breaking elongation of the steel wire is almost zero, once the upper and lower layers of steel wires are simultaneously cast, the corrugated plastic steel plate strip cannot be bent and cannot be spirally wound to form a pipe, so that the lower layer of steel wire and the upper layer of steel wire cannot be simultaneously cast when the corrugated plastic steel plate strip is extruded.
And then the corrugated plastic steel plate strips are sent into a pipe forming machine for spiral winding, a sizing material is extruded between the plastic steel plate strips by a small extruder, two adjacent corrugated plastic steel plate strips are firmly bonded, upper layer steel wires are added into shallow grooves at the top ends of the reinforcing ribs, and a small extruder is used for extruding thin polyethylene to cover and protect the upper layer steel wires.
The corrugated plastic steel plate strips are bonded at the highest positions of the corrugated reinforcing ribs, so that the maximum bonding area is ensured, and the pipe is firmly bonded.
The plastic steel plate strips are not bonded enough by the temperature of extruding the sizing material, and the plastic steel plate strips can be bonded most reliably only by applying pressure between the plastic steel plate strips. Therefore, a two-stage rotary clamp is added on the equipment to clamp the corrugated reinforcing ribs of the plastic steel plate strip, so that the reliable bonding and the integration of the pipe are ensured.
The foundation plate 14 is a first layer of plastic steel plate strip, and the deep color is a reinforcing part wound after forming a pipe.
On the basis of the above, a butt joint belt 3 is added, so that the wound and bonded parts of the two plastic steel plate belts are reinforced, and the joint part is prevented from being torn under the condition of pressure in the pipe.
The corrugated plastic steel plate strip is reinforced by layered steel wires, a space and a plastic support are arranged between two layers of steel wires, and the two layers of steel wires are respectively cast.
When the corrugated plastic steel plate strips are spirally wound to form a pipe, the adjacent plate strips are bonded at the highest position of the corrugated reinforcing ribs to obtain the maximum bonding area.
When the adjacent corrugated plastic steel plate strips are bonded, a two-stage rotating clamp is adopted to apply enough pressure to the bonding surface so as to ensure the bonding strength and the integrity of the pipe.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention.
