China's first large-tonnage multi-function hydraulic static pile driver is 20 years old this year!

"It took 20 years! Make a big profit!"

Looking at the hydraulic static pile driver that has been baptized by the wind and rain, Han said with emotion!

This is the first equipment independently developed by Shanhe Intelligent, and it is also the first large-tonnage multi-functional hydraulic static pile driver in China.

Cooperation

Twenty years ago, Han Zong, who has been engaged in the pile foundation construction industry in Guangdong for ten years, followed the Guangdong Basic Engineering Company to go to Changsha for an inspection and wanted to buy a desirable static pile driver!

At that time, China's soft and weak foundation pile foundation construction equipment technology is still relatively backward. The drop hammer pile machine and diesel hammer construction commonly used in precast pile construction have impact vibration, noise and soot splash pollution, construction quality and efficiency are low, and environmental protection is poor. . Most of the hydraulic static pile drivers on the market have high power, high energy consumption, poor reliability and low construction efficiency, which cannot meet the requirements of construction and engineering quality of large diameter and high bearing capacity pipe piles.

"We have visited several companies and have not found a suitable manufacturer. Finding Teacher He is recommended by experts in the industry!"

At that time, Shanhe Intelligence has not yet been established, not to mention the product, and there is no prototype. The two sides have carried out in-depth exchanges around the theory and concept.

During that conversation, Professor He Qinghua showed his team's latest research and development results in the field of hydraulic static pile drivers.

In combination with the national major technological equipment innovation development project, after long-term research, Professor He found that there is a “mutation” law of the load of the pile-pile resistance transiently increasing in the pile-pressing process. Based on this, he founded the “quasi-constant power” design theory and Two or more pairs of hydraulic cylinder step-by-step piles are the key technology system realization method, which realizes the high efficiency and energy saving of hydraulic static pile driver, and meets the large tonnage (600 tons or more) for large diameter and high bearing capacity pipe pile construction. The design of the pile driver laid the theoretical foundation.

Based on the above-mentioned innovative theory and core technology, Professor He invented the "hydraulic static pile driver", "multi-point equalizing pile-pile mechanism for pile driver" and "a static pile driver for crushable piles and angle piles" ", effectively solve the engineering construction problems such as the prefabricated pile body is easy to be damaged and the construction quality cannot be guaranteed.

After the exchange, there was no hesitation. Han always took out 500,000 yuan as a prepayment, and entrusted a 680 static pile driver to Professor He!

"Some people say that I am too rash and too impulsive! I don't think it! At that time, we communicated very carefully with Teacher He, and the main details, such as how to use the oil seal to the cylinder, are all mentioned! More importantly, at that time, domestic The pile drivers are all in the middle and low-pressure route, and Mr. He took the lead in proposing a high-pressure route. This alone is enough to impress me. In general, we are impressed by Mr. He’s personal charm, technical strength and professionalism! The cooperation is a hit!"

Twenty years of piling a million meters

Time flies, twenty years have passed in the blink of an eye!

Twenty years later, Shanhe Intelligent, which started from hydraulic static pile driver, has successfully developed into an international enterprise group with a certain influence at home and abroad. It ranks among the top 50 global construction machinery enterprises and exports more than 100 products. Countries and regions.

In the past 20 years, the cooperation between the two sides has also continued.

“We have successively bought more than one Shanhe smart equipment! With these equipments, we have basically participated in the key projects in Guangzhou, and we have also participated in the basic projects throughout the country!”

Looking back on the cooperation process of the past 20 years, the most common thing for Han to relish is the hydraulic static pile driver.

"It has been 20 years since now, and it can be used normally. It can piling more than 50,000 meters a year! It is roughly calculated. In the past 20 years, this pile machine has said that it has also hit a pile of 1 million meters!" Said.

Since the beginning of the cooperation, Han has become a loyal fan of Shanhe Intelligence. Because it is the first equipment sold by Shanhe Smart, there have been users from time to time to watch and understand this equipment, and Han always tirelessly and patiently introduce to you. Under his influence, how many users have joined the team that purchased Shanhe smart devices has been counted.

"Through the two years of cooperation with Shanhe Smart, I have always insisted on my choice! In the future, I will continue to adhere to it! I believe that together with Shanhe Intelligence, we will be able to achieve win-win cooperation and achieve greater breakthroughs!"
