Project Overview

The Hainan Haigang Green Circular Industrial Park is located in Changjiang County, Hainan Province, China. As a key component of the Hainan (Changjiang) Clean Energy High-Tech Industrial Park, it is one of Haigang Group's flagship projects for promoting the circular economy during its long-term development strategy. The park covers a planned area of approximately 2,100 mu (about 140 hectares) with a total planned construction area of approximately 1.4 million square meters. Focusing on resource recycling, comprehensive solid waste utilization, green manufacturing, technological innovation, and industrial incubation, the project aims to establish a landmark green industrial cluster within the Hainan Free Trade Port.

As one of the park's major developments, the Changjiang Green Industry Incubation Base requires high standards for foundation bearing capacity, ground uniformity, and long-term settlement control. During construction, the contractor selected the HC84 Rapid Impact Compaction (RIC) Machine for ground improvement, providing a stable and reliable foundation for the subsequent structural works.

Why Choose the HC84 Rapid Impact Compaction Machine?

Industrial park developments commonly involve challenging ground conditions, including extensive fill areas, localized soft soils, and transitions between different fill materials. Conventional vibratory rollers are often unable to effectively improve deeper soil layers, while traditional dynamic compaction may be limited by working space, safety clearance requirements, and construction efficiency.

The HC84 Rapid Impact Compaction (RIC) Machine combines high impact energy with excellent mobility. Mounted on a 40–45-ton excavator, it rapidly improves ground conditions through continuous high-frequency hydraulic impacts. It is particularly suitable for:

• Industrial parks and factory foundations

• Road and municipal infrastructure projects

• Large-scale fill areas

• Sites with restricted working space

• Projects requiring minimal disturbance to adjacent structures

Compared with conventional dynamic compaction methods, the HC84 offers continuous operation, convenient relocation between work areas, and greater flexibility in adapting to different construction zones, thereby improving overall site productivity.

HC84 Equipment Specifications

The project utilized the HC84 Rapid Impact Compaction Machine with the following technical specifications:

The HC84 is a medium-energy Rapid Impact Compaction system that offers an excellent balance between compaction efficiency, equipment compatibility, and operational flexibility. It is widely used in industrial parks, logistics centers, road construction, and a variety of ground improvement applications.

Project Application

During the construction of the Changjiang Green Industry Incubation Base, the HC84 Rapid Impact Compaction Machine was employed to carry out the ground improvement works.

Mounted on an excavator, the equipment can be quickly relocated between different work areas while allowing operators to adjust the working position according to actual site conditions. This flexibility enables efficient operation even under complex ground conditions.

The continuous high-frequency impacts generated by the hydraulic system effectively increase soil density within the designed improvement depth, enhance overall ground uniformity, and provide a stable foundation for subsequent structural construction.

During the project, the HC84 demonstrated several key advantages:

• Excellent mobility and adaptability to complex job sites

• Stable impact energy with high continuous working efficiency

• Minimal disturbance to surrounding structures

• Flexible integration with different construction methodologies

• Capable of meeting the quality and productivity requirements of industrial park foundation construction

  

Project Progress

To date, the main roadworks and landscaping for the Changjiang infrastructure supporting project have been substantially completed. Supporting utilities, including water supply and drainage, electrical systems, and traffic facilities, have also been completed, bringing the overall project progress to approximately 98%.

Earthworks and ground improvement for the Changjiang Green Industry Incubation Base have been successfully completed. The project is currently progressing with the construction of the main structures as scheduled, providing a solid foundation for the overall development of the industrial park.

Typical Applications of the HC84 Rapid Impact Compaction Machine

The HC84 is suitable for a wide range of ground improvement applications, including:

• Industrial park development

• Factory foundation construction

• Road subgrade improvement

• Bridge abutment and culvert backfill compaction

• Port yards and container terminals

• Logistics parks

• Municipal infrastructure projects

• Energy and utility projects

• Airport and railway infrastructure

For projects requiring an effective ground improvement depth of approximately 2.5–6.5 meters, the HC84 provides an excellent balance of construction efficiency, equipment investment, and compaction quality, making it an ideal solution for medium-depth ground improvement projects.

The HC84 is one of the Rapid Impact Compaction systems developed and manufactured by Taian Hengda Machinery Co., Ltd. Utilizing continuous hydraulic rapid impact technology, it can be mounted on 40–45-ton excavators to deliver fast and efficient ground improvement.

The HC product range covers multiple energy levels, from light-duty to heavy-duty models, meeting the ground improvement requirements of roads, bridges, airports, ports, industrial parks, and large-scale infrastructure projects.
