What preparatory work should be done before the start of trenchless directional drilling construction?
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.
GS10000-L Shandong Pipeline & National Pipeline Beima South River Oriented Crossing Project
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.
Goodeng Machine Horizontal Directional Drilling Construction Technology - Drill Tools Selection
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.
Advantages and Applicable Conditions of Static Pile Drivers of Goodeng Machine Brand
Advantages and Applicable Conditions of Static Pile Drivers of Goodeng Machine Brand
Static pile drivers install precast piles by applying steady hydraulic pressure instead of impact force, making them widely used in modern foundation engineering.
Capable of directional drilling through gravel, soil and rock formations.
Drilling in sand, gravel, pebbles and fractured formations involves great difficulty in hole formation. Such formations are known as mechanically dispersive formations. Due to the lack of cementation between particles, the borehole wall is prone to collapse during drilling. For such formations, mud or high-viscosity slurry is used to stabilize the borehole wall. The key to solving the problem is to increase the cementation force between particles of the borehole wall.
Goodeng Machinery Global Horizontal Directional Drilling Rig Case Studies
Goodeng Machinery's G-series horizontal directional drilling rigs have made a dazzling debut in the European market, achieving immediate success. The G200-LS boasts a maximum push-pull force of 830KN and a maximum torque of 35300N.m, winning over customers with its outstanding intelligent performance. The first crossing project involved soil layers, using Φ600mm HDPE pipes. The longest single crossing distance was 907m, with a total project length of 4.5km

How to choose a high-quality horizontal directional drilling (HDD) rig manufacturer in China?
Choosing a high-quality horizontal directional drilling (HDD) rig manufacturer is a comprehensive decision-making process that requires consideration of multiple dimensions, including technology, service, market reputation, and your own needs. Below is a systematic selection guide and key considerations to help you make an decision.
Scope of Representation for De, DN, d, and ф
De: Denotes the outside diameter of PPR pipes, PE pipes, and polypropylene pipes.
• DN: Denotes the nominal diameter of polyvinyl chloride (PVC) pipes, cast iron pipes, steel-plastic composite pipes, and galvanized steel pipes.
• d: Denotes the nominal diameter of concrete pipes.
• ф: Denotes the nominal diameter of seamless steel pipes, specified in the format of outside diameter × wall thickness (e.g., ф100 corresponds to 108×4).
