道路地下打孔机设计

摘要

道路地下打孔机是用于地下钻孔的机器。它广泛用于地质侦探、矿产侦探、水文水井钻凿、工程建筑的基础施工、矿山开采及其他各种用途的钻探生产中。目前，打孔机已发展成为品种众多、门类较齐全的专业机械。

设计钻机时，首先应以保证设计的打孔机能高效、优质、安全、低耗完成打孔为前提，使设计的钻机技术先进、经济合理，具有良好的经济技术指标。

本次设计的打孔机，是针对于小规模的打孔。综合考虑了所有相关问题，设计的一款地下打孔机。本文从理论到实践对水平定向道路地下打孔机设技技术及方法进行了系统的分析和研究，特点是针对当前的定向钻进施工过程中在应用方面存在的

问题进行了较深入的分析，从工程实施的角度出发，着重论述了如何提高定向钻机在地下管线铺设中的安全性和施工质量，即采用钻机铺设地下管线应以前期的资料收集、地层分析及地下管网探测为前提和基础，以定向轨迹的设计和计算为理论依据。

定向钻孔的施工是关键，个组件满足使用条件是重要保证。

ABSTRACT

Road underground drilling machine is used for underground drilling machines. It is widely used geological detective, Detective mineral, water well drilling, construction of the foundation construction, mining and other purposes, drilling production. At present, the drilling machine has developed into many species, the professional classes more complete machinery.

Design rig, the first should be to ensure that the design of the drilling mechanism efficient, high quality, safe, low completion of drilling as the prerequisite to the design of the rig technologically advanced, economically rational, has a good economic and technical indicators.

The design of the drilling machine, is to address small-scale drilling. Comprehensive considered all the relevant issues, a design of the underground drilling machines. This article from theory to practice on the ground floor level of road directional drilling technology and technology-based methods for the analysis and research system, characterized by a view of the current construction of directional drilling in the process of the application Issue a more in-depth analysis, from the perspective of the project, focused on how to improve the Directional Drilling Machine in the laying of underground pipeline in the safety and construction quality, that is used to rig the laying of underground pipeline to the pre -Data collection, analysis and formation detect underground pipe network as the prerequisite and basis for directional path to the design and theoretical basis for the calculation.

Directional drilling the construction is the key, component meet the conditions of use is an important guarantee

Key words: drilling machine, drill, drill pipe
