Guide: Taiwan Honghua Construction Co., Ltd. has been mainly engaged in hydraulic dredging and maritime construction since its establishment in 1981. At the end of 2010, the company purchased two atlas amps# 8226; Copco ROC L6 full hydraulic down the hole open-pit drill (hereinafter referred to as ROC L6 drill), and applied it to Jinmen water

since its establishment in 1981, Taiwan Honghua Construction Co., Ltd. has mainly engaged in water conservancy dredging and maritime construction. At the end of 2010, the company purchased two Atlas Copco ROC L6 full hydraulic down the hole open-pit drilling rigs (hereinafter referred to as "roc L6 drilling rigs") and applied them to the harbor basin dredging project of Jinmen Shuitou wharf, successfully creating a precedent for the application of full hydraulic down the hole open-pit drilling rigs in maritime engineering

project overview

the Golden Gate Shuitou wharf is the largest marine rock removal project in Taiwan's history, carrying the heavy responsibility of providing better services for mainland tourists to Taiwan. The total amount of rock to be blasted is 240000 cubic meters, with a total investment of more than NT $2 billion. The project was officially started in 2000, but due to the complex distribution of rocks in Kinmen area and the great impact of tides, most of the rocks need to be drilled and blasted on the seabed, and Taiwan has no company specializing in underwater rock blasting, so the construction period was seriously delayed. Since taking over the project at the end of 2010, Taiwan Honghua Construction Co., Ltd. has abandoned the traditional artificial seabed drilling method and changed to the offshore mechanical drilling method. Two Atlas Copco ROC L6 drilling rigs were placed on the newly fixed "Hongfu" support platform, drilling and blasting from above the rock, thereby reducing the impact of tidal currents on offshore drilling, and spring tension and compression testing machines Spring change testing machine and spring fatigue testing machine successfully caught up with the construction period under the condition of a substantial increase in workload

the mechanical drilling efficiency is high

according to Luo Xiangyu, the project manager of Taiwan Honghua Construction Co., Ltd., due to the complex geological structure of the port basin dredging project of Jinmen Shuitou wharf, there are many problems, such as large wear and tear on drilling tools, high difficulty in underwater operations, and easy to be affected by tides, Therefore, it is very suitable to adopt an efficient offshore mechanical drilling method. Compared with the traditional method, this construction method mainly has the following advantages:

1. Accurate positioning: the traditional manual drilling can not accurately locate under the sea and can not effectively control the hole spacing, which often leads to the situation that the rock cannot be blasted, while the offshore drilling rig can be constructed on a stable support platform and can effectively control the hole spacing and angle

2. It can work for a long time: traditional manual drilling can only work for hours a day even if the weather is good, because it needs to dive underwater for operation, while offshore drilling rigs can work almost 24 hours a day

3. Not limited by weather and seabed conditions: in addition to bad weather and inability to work in the sea, traditional manual drilling often fails to drill to a fixed depth, and is vulnerable to the influence of sediment on the rock, which is often too thick to drill into the rock

4. It can accurately control the drilling depth: because the fixed height of the offshore platform can cooperate with the existing depth gauge of machines and tools to accurately control the drilling depth, it will not cause waste of explosives

Taiwan Honghua Construction Co., Ltd. boldly introduced two Atlas Copco ROC L6 drilling rigs according to the needs of the project, and became the first enterprise to successfully use Atlas Copco full hydraulic DTH open-pit drilling rigs in maritime engineering
