什么是潛孔技術(shù)和應(yīng)用？

潛孔技術(shù)是應(yīng)用于礦區(qū)采石業(yè)，由于沖擊錘沖擊孔洞底部，洞深得于延長，沖擊能量沒有因?yàn)槁?lián)系鉆桿而流失，然后應(yīng)用井業(yè)方式Zui后隨著鉆頭，鉆具的研發(fā)，潛孔的深度，大小得于擴(kuò)大。

What Is DTH?

Down the hole drilling was developed for mining and an impact hammer in the bottom of the hole. With theDown-The-Hole hammer drilling depths could be increased as impactenergy is not wasted in drill rod connections.

DTH drilling was adopted to well drilling industry andfinally to over burden drilling with first reamer bit inventionsand later with ring bit systems making it possible to increase thecasing sizes.

潛孔錘在表土層的鉆巖

潛孔鉆廣泛應(yīng)用于地基打樁施工，由于高出產(chǎn)率，在離岸地基施工越來越受歡迎，而且隧道施工，鉆井錨定施工也推廣開。

Overburden Drilling with DTH Hammer

DTH casing advanced drilling is today widely used in welldrilling and in construction industry and in it is gainingpopularity in off shore applications due to its high productivity.DTH drilling is used also in horizontal break through drilling, forintegrated pipe pile walls and in anchoring - just to mention fewof the common applications.

潛孔錘的優(yōu)勢：

成孔垂直度好

成孔深度長

大直徑

產(chǎn)品可靠，簡單操作

全地形施工從軟土層到堅(jiān)硬巖層

Benefits of DTH drilling

DTH drilling has several advantages compared to competingmethods:

Hole straightness

Possibility to drill long holes

Wide size range

Reliable and simple

Works in all ground conditions from soft clay to hardestrock!
