摘要： PURPOSE:To improve workability by a method wherein one end of a pipe is connected to a knife, a pipe is buried into the ground, a travelling car is made to travel, a lawn is cut, the lawns on both sides are held down along a slit and the inside of the ground is notched by the knife. CONSTITUTION:Pits are dug at both ends on a disposing projected line in the burial depth of a pipe P, and the pipe P is buried. A travelling car 1 is moved and a pipe burying device 2 connected to the car 1 is arranged into the pit, and one end of the pipe P is connected to a knife 4 at that time. A lawn G is cut continuously by a lawn mover blade 3, the lawns G on both sides of a slit are held down by a lawn hold-down member 5 along a slit, and the inside of the ground is notched gradually by the knife 4. The inside of the ground is notched by the knife 4 while one end of the pipe P bonded with the knife 4 is pulled through connecting members 6, and the pipe is moved forward in the ground while being introduced by a boring tool 61. The burying device 2 is made to reach another pit, thus penetrating the ground by the pipe P between both pits. Accordingly, the pipe P can be buried smoothly while the lawn G is held excellently.

摘要： PURPOSE:To conduct pipe burying operation by smoothly burying a pipe into the ground without digging a ditch and preventing the intrusion of soil, etc., into the pipe from the front end opening of the pipe while obviating the damage of the front end of the pipe. CONSTITUTION:Pits are dug at both ends on a pipe disposing projected line respectively while a pipe P longer than a distance between the pit and the pit dug at both ends on the pipe disposing projected line is arranged on the extension of the pipe disposing projected line, and a knife 4 is disposed into the pit, in which one end of the pipe P is arranged. One-end opening section of the pipe P is brought to the state, in which the opening section is covered with a cap 8, and one end of the pipe P is connected at a proper position of the knife 4 through connecting member 6. The knife 4 is moved along the pipe disposing projected line by a moving means, thus notching the inside of the ground by the knife 4 while pulling the pipe P as the pit is bored by the boring tool 61 of the connecting members 6, then penetrating and disposing the pipe P in the ground.

摘要： PURPOSE:To provide a pipe embedding method that is inexpensive in construction expenditure, less in a traffic obstruction due to construction, high in working efficiency and makes it applicable even in a distance between long intervals. CONSTITUTION:A keyway-form ditch using a spherical part as the bottom part lying between a starting side shaft and an arrival side shaft constructed at both sides of a pipe embedding predetermined position is dug by a chain type ditching machine 28 with a pair of semispherical drums 41 and 42 attached with a lot of bits 43 on the circumference. After a pipe is arranged in the spherical bottom part of the keyway-form ditch dug out from a pit mouth, the keyway-form ditch arranged with the pipe and each shaft are refilled.

摘要： PURPOSE:To provide a lawn grass cutting draining device with simple mechanism by having a cutting part in the rear part of a motive power unit for rubber tire, vertically moving an iron-working cutter body mounted thereon to cut lawn grass, cutting a groove, and burying a pipe body therein together with pumice. CONSTITUTION:While a motive power unit for rubber tire is advanced at minute speed, a cutting part 3 formed of a base 31 mounted on a car body rear part; a cutting tool mounting member 32; a parallel link 33; and a hydraulic cylinder 34 is vertically moved by hydraulic operation. An iron-working cutter body 4 mounted on the cutting tool 3 has a form having an edge form on the advancing side and a camber toward the rear part, and cuts a groove while cutting lawn grass and surface earth, and the soil is once discharged by a soil discharging plate 14. In the cut groove, a pipe body 9 guided by a pipe body feed roller 10 is laid so that it is enclosed by the pumice supplied from a hopper 5. After laying, the discharged soil is back filled by a soil collecting plate 16, and compacted by a compaction roller 12.
