In trenchless construction, the skill of operating a horizontal directional drilling rig directly determines project efficiency, cost, and safety. We have summarized six practical techniques to help you maximize equipment performance and confidently handle complex working conditions.

Our Goodeng G100 (45-ton pulling force) just landed on the construction site and was immediately put to work by the customer.

Application Scenarios and Advantages of Integrated Goodeng Machine Down-the-Hole Drills

Integrated down-the-hole (DTH) drills represent a highly integrated, self-contained rock drilling solution that combines a power unit, air compressor, hydraulic system, drilling mechanism, and control system into one compact crawler chassis. Unlike split-type setups that require separate compressors and auxiliary equipment, these all-in-one machines deliver superior mobility, efficiency, and reliability for surface rock drilling. They have become indispensable in mining, quarrying, infrastructure, slope stabilization, and geotechnical projects worldwide.

The pre-construction preparations for trenchless directional drilling directly determine the success or failure of the project. The entire process can be summarized into five core steps: survey, design, site preparation, equipment check and pipe material preparation.

A brief but enthusiastic departure ceremony was held at Jiangsu Goodeng Heavy Machinery Technology Co., Ltd. Accompanied by the roar of engines, Goodeng Machinery's independently developed GSE12000-L extra-large new energy horizontal directional drilling rig officially set off for the construction site of the Sichuan-East Gas Pipeline II (hereinafter referred to as "Sichuan Pipeline II"), a major national energy strategic corridor. This marks another solid and powerful step forward for Goodeng Machinery in implementing the national "dual-carbon" strategy and promoting green equipment to support energy construction.

Horizontal Directional Drilling Machines to Brazil, Receiving High Praise for Infrastructure Contributions

Two extra-large horizontal directional drilling rigs, the GS10000-L and GS6000-T, from Guden Machinery were simultaneously deployed in Yantai to assist in the construction of the Shandong Pipeline East Trunk Line natural gas pipeline and the national natural gas pipeline network. They simultaneously directionally drilled through all rock, using 1219mm diameter steel pipes, with total construction lengths of 700m and 725m respectively.

Horizontal directional drilling ( HDD) is an advanced trenchless construction method that uses a guidance system to precisely control the drilling trajectory, enabling underground pipelines to cross obstacles.
