A drip emitter is provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. Water enters the emitter through a first inlet and proceeds into a first chamber. When the water pressure is above a predetermined level, a one-directional valve opens to allow fluid flow past the first chamber, through a tortuous path flow channel, and through an emitter outlet. A second inlet is used to compensate for water pressure fluctuations in the supply tube to maintain output flow at a relatively constant rate. Water enters the second inlet and presses a flexible diaphragm toward a water metering surface to provide pressure-dependent control of the output flow. A copper member is mounted to the emitter over the emitter outlet to prevent plant root intrusion into the emitter outlet.

The embodiments of the present application provide a method for making continuous micro-irrigation tubing, the continuous micro-irrigation tubing so made, a method for performing irrigation using the said continuous micro-irrigation tubing, and the application of the said continuous micro-irrigation tubing in agricultural irrigation, wherein the method for making continuous micro-irrigation tubing comprises: preconditioning a filler; blending the preconditioned filler with high-pressure polyethylene resin at a predefined weight ratio and making said filler and resin into filler pellet; making preformed tubing from the filler pellet; and threading the preformed tubing into a high-temperature extractor in which continuous extraction is performed to make continuous micro-irrigation tubing. The method enables the making of continuous micro-irrigation tubing containing micro-pores on the tubing wall. After the continuous micro-irrigation tubing is filled with water, water exudes through the micro-pores.

An irrigation implement may include a member having a first end a second end. The first end may be open and the second end may include a pinched seal. The member may further define an opening disposed toward the second end, and be configured to enable an irrigation tube to be attached to the opening such that the opening is sealed by the irrigation tube. A process may use a pinching and heating process to self-seal the irrigation implement on one end in producing the irrigation implement.

A pipe retrieval machine includes a frame defining a decoupling region and a travel axis and a transporting mechanism supported on the frame. The transporting mechanism has a first gripping structure adjacent an infeed end of the machine and a second gripping structure adjacent an outfeed end of the machine. The decoupling region is between the first and second gripping structures. The machine has a drive system to move the first and second gripping structures at a steady state speed to direct a pipe along the travel axis. The pipe retrieval machine includes one or more safety features to stop the drive system either automatically or through manual action, one or more safety features to inhibit or prevent damage to components of the decoupling region in the event of a malfunction, or both. Methods of operating a pipe retrieval machine include any of the operation procedures, method steps, safety features, and/or functions as described and in any combination.

Disclosed is a landscaped surface applicable to all types of vehicles, which includes a frame with a settling base that rests on a detachable supporting element or directly on the roof of the vehicle, inside which there are separator partitions and a root development base made of flexible and light hydrophilic material, with a reticular structure that retains a volume of water of between 10 and 30 times the weight thereof, expelling the excess via drainage openings arranged in the lower area of its vertical face of the frame. There is a layer of covering vegetation on the root development base and a mesh secured to a fastening flap in the high part of the frame.
