一锥成大开膛火箭锥一锥成大开膛火箭锥是地方国营叶县机械厂在各级党委领导下,为了加快机井建设速度,该厂职工深入钻研经过两昼夜的苦战创制成功的。其优点是:(1)工效高,吃土利,出锥快,尤其是锥肚是大开膛(可以随意开合),倒土容易,1—1.5天可打一眼八丈深的机井。连打眼下管只需30余个工日。(2)技术容易掌握,使用方便。(3)打井、圈井均在井上操作,不用下井,施工安全,(4)性能好。不管在平原、洼地和山区滑石、石、矼石、流沙较少的地区均可推广使用。(5)制造简单、省料,一般小型机械厂都能制造(每个锥重185斤),符合多快好省的精神。
A cone into a large open rocket cone cone into a large open rocket cone is a local State Yexian Machinery Factory under the leadership of party committees at all levels, in order to speed up the construction of wells, the plant workers in-depth study after two days of hard fighting success. Its advantages are: (1) high work efficiency, eat Tuli, a cone faster, especially the taper is big open (you can arbitrarily open and close), overturned easily, 1-1.5 days to play a good eight feet deep wells. Even the current management of the pipe just over 30 days. (2) technology easy to grasp, easy to use. (3) wells, lap wells are in operation, do not go down, construction safety, (4) good performance. Whether plains, depressions and mountains talc, stone, stone, quicksand less areas can be promoted. (5) manufacturing simple, save material, the general small machinery factory can manufacture (each cone weighs 185 pounds), in line with the spirit of more fast and happier.
