摘要： PURPOSE:To conduct rectilinear propagative drilling easily by mounting a dril with a bit on the end face of a nozzle head installed to a shaft and forming a jet at a place, where the ultrahigh pressure water of the drill does not interfere in bit blades. CONSTITUTION:A nozzle 11 is set up to the front section of a nozzle head 10, and connected to an ultrahigh pressure water supply source by an ultrahigh pressure water path 12. The nozzle 11 is connected to a pressure-air supply source from a pressure air path 13, and drilling is performed by a water jet while blowing out pressure air from a pressure-air blow-off port 25. A drill 20 with a bit is fixed onto the nozzle head 10 by four bolts 14, a guide hole is drilled on an axis by a drill 21, and cutting and drilling are carried out by the water jet from a jet 24. The drill 20 with the bit is placed at a frontest end and the drill 21 bores the guide hole at that time, and the whole drilling device is borne, thus constantly holding the direction of drilling in the rectilinear propagative direction.

摘要： PURPOSE:To execute drilling work under stabilized and uniform state by attaching an outer tube to a driving motor of a drilling machine through supports and by jetting water jet through a nozzle. CONSTITUTION:An outer tube 8 is attached to the outside of a driving motor 2 through a plurality of supports 7, and end edge 8a of the outer tube is positioned in front of a nozzle 1. When drilling a bore, water jet 4 is ejected through a nozzle 1 while the nozzle is driven in revolution by the driving motor 2, and a drilling machine A is thrust forward with a propelling device. The drilling machine is moved forward continuously at a speed corresponding to the drilling speed by the water jet 4, and excavated earth is allowed to flow, together with the jetting water, to a bore 6 through a gap between the internal wall of the outer tube 8 and the outer circumference of the driving motor 2, and is furthermore discharged to the outside. Thereby, the drilled bore 6 is made in a uniform size slightly larger than the external size of the outer tube 8, and the drilling is made stably without being influenced by self-weight of the drilling machine even in the case of horizontal drilling.

摘要： PURPOSE:To prevent surface crack of a shape steel flange by arranging plural support rolls below a mold and also contactingly rolling while bringing this support rolls into contact with recessed grooves in short sides of the cast billet. CONSTITUTION:The short side support rolls 41 having flat face 41a and inclined faces 41b at upper and lower sides thereof are prepared and supported at shafts as integrating with the shafts 8 or turnable to the shaft 8. Then, inclined angle thetaof the inclined face 41b is set at almost the same angle as an inclined angle of the recessed groove 3c in the cast billet 3. Plural number of the short side support rolls 41 are arranged below the mold 1 at both short side of the cast billet 3. By this method, as the recessed grooves 3c in the short sides of the cast billet 3 are supported with the rolls 41, internal crack at the recessed grooves 3c caused by pushing-back of the rolls 2 is prevented. Therefore, the surface cracking of the shape steel flange as the product is prevented in the rolling process.
