工程钻机的设计讲解.doc

摘 要 GCPS—20型钻机是一种复合式多功能钻机，为适应我国深基础工程和连续墙以及水利工程、桥梁工程的发展与需要，结合大口径钻机灌注桩和地下连续墙施工的特点，为解决在复杂地层、硬岩中成孔而研制，特别卵石层、基石、漂石层能大幅度提高施工效率，在各种成孔方法中是比较经济有效的方法。 钻机是集回转、冲击钻进工艺于一体的多功能复合型钻机，用转盘回转钻进时可用于第四世纪覆盖层，冲击钻进时可用于卵石、灰岩、花岗岩等硬岩地层。 本钻机的特点是结构简单，紧凑，而且各种操作手柄布置合理，操作简单，便于使用与维护。 关键词： 冲击钻进 变速箱 减速器 转盘 Abstract The types GCPS-20 drill the machine is a kind of compound type multi-function drill the machine, in order to adapt the our country development and demands of the deep foundation and consecution wall and marine hydraulic engineering, the bridge engineering, combine the big caliber to drill the machine to infuse to note the stake and the characteristics of underground continuous wall construction, in order to solve to become the bore but research to manufacture in complicated geologic strata, hard rock, significant exaltation of ability of special egg stone layer, sill, the stone layer construction efficiency, is a more economic valid method in variously become the bore method. Drill the machine is to gather the turn-over and pound at to drill into the craft in the integral whole of multi-function and compound type drill the machine, can used for to overlay the layer the fourth century while using to turn the dish turn-over to drill into, can used for the hard rock geologic strata of egg stone, ash rock, granite...etc. while pounding at to drill into. Drill the characteristics of the machine originally is a structure simple, tightly packed, and various operation hand handle arrange reasonable, operate in brief, easy to usage and support.
