G341 National Highway Improvement and Reconstruction Project

Project Information

• Road Classification: An upgrade and reconstruction project for a national highway, included in China's 14th Five-Year Plan for Highway Development.

• Technical Standard: The main alignment is designed as a Class I Highway with dual four-lane carriageways, with a design speed of 80 km/h.

• Jingyuan Section Overview: The route extends 44.5 km, with a 15.2 km Jingyuan Link Road constructed simultaneously, connecting Wujiakou (interchange with G6 Expressway) to Haojiaping, and passing through the townships of Dongwan, Mitan, and Beiwan.

• Current Status: As of July 2026, the project land received approval from the State Council in September 2025. The project is now in the full-scale construction phase, with work already underway on several priority sections, including the commencement of tunnel excavation.

G341 is a major east–west transportation corridor connecting Ningxia and Gansu, playing a vital role in improving Jingyuan's transportation network and promoting regional economic development.

Rapid Impact Compaction in China has just begun to develop, but because China's construction projects have been widely used under the promotion of the environment, the market demand has gradually increased, HC Rapid Impact Compaction commodity sales market as a whole shows a hundred flowers, the cause of prosperity of the situation, the field of the whole process of red. In the last century, Yang Shiji researchers at the Highway Research Institute of the Ministry of Transport first clearly put forward the needs and proposals for such compaction machinery, stipulating that the actual effect of compacting is not less than 25kJ impact roller, which can ribblow the sub-level rolling qualified position of the impact roller that is inconvenient for engineering construction, and does not destroy the original sand structure and adjacent buildings. Authorized to entrust Guangzhou Evergrande Ramming Engineer title Cao Bin friends to design and conceive design schemes for China's impact rammer. In 2003, At the beginning of this year, China's first Rapid Impact Compaction was launched in Tai'an, Shandong Province. The first sample had a cone quality of 2.5t and a ramming potential of 30 kJ, and a 5t wheel loader was selected as a load-bearing machine. After the inspection of xi'an road construction machinery testing center of the Ministry of Transport, and the integration of new highways in Gansu, Anhui, Guangdong and other provinces to carry out experimental scientific research on the practical effect of Rapid Impact Compaction.

"夯神"manufacturer key development and manufacture of hydraulic high-speed rammer, hydraulic rammer, Rapid Impact Compaction, excavator mounting machine hydraulic rammer, hydraulic impact rammer, milling machine, flat plate rammer, hydraulic pile hammer and other ground hydraulic compaction machinery and equipment, hydraulic rammer performance parameters are specifically HC300、HC240、HC210、HC180、HC150、HC108、HC84、HC60、HC42、HC36、HC16、HC12、HC08、HC04, if you want to know more detailed model specifications of the main parameters, Warm welcome to call for information. The basic principle of the hydraulic high-speed rammer is basically consistent with the principle of all compaction machinery, and the use of mechanical energy to convert impact performance to carry out the compaction work, that is, according to the continuous improvement and reduction of the heavy hammer type, lay a good foundation or backfill the slag, and then achieve the purpose of increasing the relative density.
