Definitions

  • the present invention relates to a propulsion process of buried pipe, and more particularly to a so-called propulsion process for burying an underground pipe such as sewer without excavating the soil from the ground surface, by forming a burying hole horizontally in the soil from a shaft, and propelling while sequentially burying the pipe in the formed burying hole.
  • the propulsion method is not necessary to excavate the ground widely along the burying route, the propulsion method is intensively researched and developed as a method favorable for the installation site where the traffic volume is large and it is difficult to limit the traffic.
  • a shaft is excavated and formed in the ground, and a burying hole in the horizontal direction is formed from the side of this shaft into the ground, by a device called the leader.
  • the burying hole is formed by digging the ground by earth auger or other digging means attached to the leader, or by compacting the ground at the conical tip portion of the leader, and either method is selected depending on the soil properties and installation conditions.
  • a buried pipe cut in a specific length is connected at the rear part of the leader.
  • the buried pipes of specific length are coupled one after another and extended in length.
  • propelling force is applied by a jack installed in the shaft to propel the buried pipe row and the leader, while the burying hole is formed and buried pipe is installed by the leader.
  • the reason of using buried pipes of specific length in the propulsion process is that the handling length of the buried pipe is limited depending on the space of the shaft in order to propel prefabricated pipes into the burying hole through the shaft. Besides, to transport the pipes from the pipe mill to the site of installation and store them, it is necessary to use pipes of fixed size.
  • the seam of the buried pipes of specific length is connected by butt-to-butt adhesion of the pipe ends, or fitting the pipe end to the collar.
  • a water stop rubber is set on the abutting face of the pipe and collar to prevent invasion of ground water.
  • the seam adhesion may be separated, the collar and the water stop rubber may be separated, or the end of the buried pipe may be broken.
  • the seam junction is imperfect, ground water or sand may enter the buried pipe, or the planned water flow of the pipe may not be obtained when used as the sewer, or the water matter flowing in the pipe may lead into the ground to induce pollution problems.
  • the first invention presents a propulsion process of buried pipe comprising the steps of forming a burying hole by propelling the leader in the ground, and propelling and burying the pipe in the burying hole, wherein a long hoop-shaped pipe material made of an elastic material is sequentially curved to joint the side end to form an endless pipe, and this endless pipe is successively inserted and propelled into the burying hole.
  • the leader is available in various types, that is, the type having earth auger or other digging means, the type having a tip for compaction, and the combined type, and any type may be employed.
  • muddy water is supplied and circulated from the leader into the ground, and the excavated soil is discharged together with the muddy water.
  • direction changing means such as direction control jack for changing the direction of the tip
  • the direction of the burying hole may be easily corrected.
  • the practical structure of this direction change means may be same as in the conventional leader.
  • cylindrical tubes of fixed size are not prefabricated as in the conventional propulsion process, but an endless pipe is fabricated at the site by using pipe material, and is propelled and buried simultaneously.
  • the buried pipe material is a plastic material such as polyethylene and vinyl chloride, which is continuously formed in a long hoop shape and is prepared in coil form to be presented for transportation and storage.
  • the width of the buried pipe material is adjusted to the circumferential length of the burying hole, that is, the endless buried pipe.
  • the width of one pipe material may be a portion of the circumferential length of the endless buried pipe divided by the number of pieces.
  • the pipe material prefabricated in a specific width may be cut to a required width at the site by matching with the diameter of the burying hole.
  • any plastic material may be used as far as it is plastic enough to curve in a cylindrical form at ordinary temperature or in heated state, and mechanically strong and durable enough as buried pipe in installed state.
  • an adhesive material or a heat-adhesive material may be used.
  • the invention employs extrusion process, drawing process, press process or other curve processing means conventionally employed in curving process of synthetic resin plate or thin metal sheet.
  • the pipe material may be curved in an arc form.
  • the pipe material may be curved at the ratio of curvature to the inside diameter of the curvature processing frame.
  • the pipe material may be temporarily softened by heating or other means.
  • either one pipe material may be curved to compose the entire circumference of the endless buried pipe, or plural pipe materials may be joined in the circumferential direction to compose the endless buried pipe.
  • the side end in the longitudinal direction is joined to form an endless buried pipe.
  • the means for joining the side ends of the pipe material may include, among others, adhesion by adhesive, heating and fusing, welding by resin welding material, ultrasonic pressure-bonding, and ordinary joining means for synthetic resins. anyway, since the side ends in the longitudinal direction are joined while feeding the pipe material continuously, a continuous working method should be employed as the joining means.
  • the propulsion support is formed in a fixed length, in a cylindrical form smaller than the inside diameter of the endless pipe to be buried.
  • the length of the propulsion support is determined in consideration of the convenience of transportation, storage and handling in the shaft.
  • the propulsion support is linked behind the leader and is successively extended.
  • the propulsion support contains, in its inside, an auger screw for driving the earth auger of the leader to send out the excavated soil behind, hydraulic and pneumatic pipings for actuating the direction change means of the leader, power cable and others.
