摘要： PURPOSE:To smoothly discharge soil and to improve excavation efficiency, by a method wherein a bucket shell is openably mounted to a bucket body, a hydraulic cylinder is provided, and a blade is vertically movably attached to a piston rod. CONSTITUTION:A blade 18 is separated from upper plates 16a and 17a of bucket shells 16 and 17 with the aid of a hydraulic cylinder 20, and the bucket shells are held in an opening attitude. The bucket shells 16 and 17 are pushed in, soil is scooped in the shells 16 and 17, and the shells 16 and 17 are closed through contraction of the hydraulic cylinder 20. The bucket shells are lifted up to a ground, the blade 18 is lowered within the shells 16 and 17 through expansion of the cylinder 20 to discharge soil. This enables smooth discharge of soil by means of the blade irrespective of quality of soil excavated by the bucket shells.
摘要翻译：目的：为了平稳地排放土壤并提高挖掘效率，通过将铲斗壳体可开启地安装在铲斗本体上的方法，设置液压缸，并且将叶片垂直地可移动地附接到活塞杆。构成：叶片18借助于液压缸20与桶壳16和17的上板16a和17a分离，并且桶壳保持打开姿态。铲斗壳体16和17被推入，铲斗16和17中挖出土壤，并且通过液压缸20的收缩使壳体16和17关闭。铲斗壳体被提升到地面，叶片18是通过气缸20的膨胀而在壳16和17内降低以排出土壤。这样就可以通过叶片平稳排放土壤，而不管桶壳挖出的土壤质量如何。

摘要： A lateral hole boring method whereby a lateral hole of a desired length is formed underground by repeatedly performing the following steps. A vertical hole is prepared, and a lateral hole boring apparatus equipped with a leading auger of a smaller length than the diameter of the vertical hole is lowered into the vertical hole to a predetermined position. The apparatus is manipulated from the ground level to advance and rotate the leading auger to bore a lateral hole. When the lateral hole has reached a predetermined length commensurate with the length of the leading auger, the advance movement of the leading auger is stopped, and the lateral hole boring apparatus is manipulated from the ground level to detach the leading auger therefrom, and is lifted above the vertical hole while leaving the leading auger in the lateral hole. A coupling auger of a smaller length than the diameter of the vertical hole is attached to the lateral hole boring apparatus outside the vertical hole, and the apparatus is lowered into the vertical hole again. Then, the lateral hole boring apparatus is manipulated from the ground level to couple the coupling auger to the leading auger left behind in the lateral hole.

摘要： @ A clamping device is provided for effecting fitment of a branch pipe connection to a main pipe which, for example, may carry gas or water. The clamping device comprises a body (11) having two pairs of opposed arms (17) forming jaws which may engage about opposite sides of the periphery of a pipe (28) and thereby be tightened. Each of the arms (17) is pivoted to the main body and a retaining bar (18) is provided secured by a clamp bolt (21) which threadably engages bosses in the body (11). The bar (18) has abutment shoulders (19) which contact corresponding shoulders on each arm (17) whereby tightening the bolts (21) causes the arms to be forced inwardly to engage pipe 28. A rod device (24) is used to fit the clamp and also to manipulate a cutting device to bore into the pipe (28). The rod device can also be used to fit the branch coupling.

摘要： PURPOSE:To facilitate excavation of the surrounding of an underground buried pipe, by a method wherein 2 sets each of vertical inner shells, a distance between which is controllable, and about semicylindrical openable outer shells are mounted to the lower end of a cylindrical body. CONSTITUTION:A bucket mounting frame 16 is secured to the lower end of a cylindrical body 10 mounted to the forward end of the arm of an excavating device, and 2 sets of openable buckets 14 and 15 are mounted to both sides of the frame 16. Each of the openable buckets 14 and 15 is formed with about semicylindrical outer shells 14B and 15B and linear laminar inner shells 14A and 15A, and the outer shells 14B and 15B are intercoupled through an openable cylinder 25. Meanwhile, the inner shells 14A and 15A are moved and secured so that a distance therebetween is controllable. This enables easy excavation of the surrounding of an underground buried gas pipe and water pipe.
