Shaanxi Longhai Xinchuang Foundation Engineering Co., Ltd. is a specialized company engaged in various types of building foundation treatment. It is a technology-based enterprise that researches and promotes new technologies in geotechnical engineering.

The company currently has more than 750 employees, consisting of 17 project departments and 112 professional technical and economic management personnel, including 1 professor level senior engineer, 9 senior engineers, and 46 engineers. The company has strong financial resources and a registered capital of 50 million yuan. It has 184 sets of various large-scale pile foundation construction equipment, including 2 B180 rotary drilling machines, 8 forward (reverse) circulation rotary drilling machines, and 12 lime soil compaction pile drilling equipment. Among them, 6 of them can achieve a compaction hole of more than 20 meters, making it a unique compaction pile drilling equipment in the northwest region. There are 40 DDC pile compactors, 4 long spiral CFG pile equipment, 6 100TM-400TM dynamic compaction equipment, 2 static pile compactors, and 33 compaction reinforced concrete compaction and expansion pile construction equipment. The construction pile diameter is Φ 350- Φ 600, and the construction pile length is 5-28 meters. The company has excellent equipment, strong technical strength, and a high-quality technical team composed of professionals from various fields. For some geological conditions that are complex and difficult to construct, our company's experts have demonstrated and studied to propose the economically feasible best solution for the construction unit, which not only ensures the quality of the project but also saves project costs, achieving good social benefits.

The five technologies developed by our company, including the equipment for compacting and expanding reinforced concrete large head piles, have obtained national patents. In long-term construction practice, we have combined the characteristics of the geological structure in northern China, and not only developed and tested the "Composite Foundation of Plain Concrete Rammed Expansion Pile and Plain Soil Compaction Pile" based on the widespread distribution of collapsible loess, but also solved the major problem of foundation treatment for high-rise buildings in self compacting collapsible loess sites. It has gradually developed into the construction of such pile types in mixed fill soil, sand layers, pebble layers, and strongly weathered rocks, promoting their application to foundation treatment projects for high-rise buildings and various industrial structures in complex geological environments, greatly reducing construction costs, shortening construction periods, and reducing environmental pollution. Such projects as PetroChina Changqing Oilfield, State Grid Lanzhou Yongdeng 750 Substation, Pingliang 750 Substation, Qianxian 750 Substation, Three Gorges Supporting Project Northwest North China Back to Back Converter Station, Lanzhou Xi'an Zhengzhou Changsha Finished Oil Pipeline Xianyang Station, Guanlv Power Plant, Yulin International Hotel, Yan'an Oriental Century Plaza, Huangling 1 million tons of coking methanol, Zhongxin Chanba, Shui'an Dongfang and other large-scale industrial and civil projects have been independently completed by our company, achieving significant economic and social benefits. Squeezing (reinforced) concrete compacted expanded piles are increasingly favored by construction units and owners due to their advantages of fast construction speed, intuitive and easy quality control, high pile foundation bearing capacity, low construction cost, strong applicability to site environment, and no pollution on site.

The company's eternal pursuit is to establish the corporate image of "Longhai Foundation, the first in Northwest China", the corporate spirit of "putting people first and honesty as the foundation", and to lead the way in the foundation treatment industry with "advanced technology and scientific management". Our company will continue to seek reputation through quality and development through reputation, and sincerely cooperate with people from all walks of life to create a better tomorrow.
