Innovation concept refers to enterprises or individuals breaking away from convention and seeking a new realm. In Jintai, regardless of technology, management, system or thought, innovation has flowed into the blood and penetrated into the bone marrow. Mr. Su Buqing's phrase, "Being brave and willing to innovate, and seeking glory from gray hair", is a true portrayal of Jintai's development path. The last part of the article tells about the eternal heart of the centennial Jintai longevity gene; This article will focus on the historical achievements of Jintai's continuous pioneering and innovation.
Products are the foundation of an enterprise, and innovation is the driving force for the continuous progress of an enterprise. Every time we fight for our mission, every time we upgrade our technology and construction methods, we can't do without Jintai people's assiduous pursuit and deep cultivation. It is the pile manufacturer represented by Jintai who is committed to the continuous exploration in the field of foundation construction that makes the fundamental change of China's pile industry from scratch, from weak to strong.
Before liberation, there was no piling machinery manufacturing industry in China. In the early 1950s, the steam pile drivers and heavy drop hammers imported from abroad in old China were all used in the foundation construction of our country, and the pile drivers' mechanical equipment and construction methods were extremely backward and simple. During the first "Five-Year Plan" period, due to the needs of national key construction projects such as Fulaerji No.1 Heavy Machinery Factory and Wuhan Yangtze River Bridge, China began to imitate foreign 3~10 tons of single-acting and double-acting steam pile drivers and β π series vibrating pile hammers of the former Soviet Union, which was the beginning of China's pile-driving machinery manufacturing industry dominated by imitation.
In 1963, Shanghai Geological Exploration Machinery Factory produced the first domestic geological exploration machinery XU-300 vertical shaft drilling rig in Shanghai. In 1967, China's first 300-meter deep water well drilling rig, SPJ 300, was developed, which has been out of control ever since. 200m full hydraulic trailer well drilling rig, 1,500m new core drilling rig, ZJ-170 oil drilling rig, 500m truck-mounted well drilling rig SPC-500, 600m trailer drilling rig SPJT-600, and BW-850 mud pump, the process equipment matched with well drilling rig, came out one after another.
In 1988, in order to solve the problem of soft soil foundation reinforcement in the Yangtze River Delta, GPP series deep jet mixing rigs were developed, which are suitable for powder jet mixing method and slurry deep mixing method. In 1999, Jintai introduced SMW construction methods and equipment, and made local adaptive transformation. In 2001, ZKD85-3 and ZKD100-3 series multi-axis drilling rigs were introduced to the market, filling the gap of domestic industry construction methods.
After the establishment of Shanghai Jintai Construction Machinery Co., Ltd. in 2002, four strategic adjustments were implemented, namely, product structure, production mode, organization and human resources, which defined a new starting point and new direction. At the same time, a new enterprise product development strategy has been formulated: based on the field of basic construction equipment, guided by market demand; Aim at the international cutting-edge technology and take technological innovation as the driving force; In combination with China's national conditions and national policies of economic development and infrastructure construction, we developed infrastructure equipment products suitable for diversified working conditions and construction technologies. Soon after, Jintai firmly seized the great opportunity that was beneficial to its own and industry development.
In 2005, the first SD10 rotary drilling rig and SG30 underground diaphragm wall hydraulic grab independently developed and manufactured by Jintai were born and successfully applied. Jintai gradually transformed from a traditional state-owned enterprise to a modern enterprise, and its products transformed from a traditional piling machine with mechanical transmission to a modern piling machine with electromechanical and hydraulic integration. In 2006, SD20A rotary drilling rig went on sale, and in the same year rotary drilling rig and grab bucket were exported. In 2008, Jintai launched the classic model of SD28 medium-sized rotary drilling rig, which sold well for more than 10 years.
In 2009, with the construction of rail transit in the first-tier cities in the north, Guangzhou and the popularization of diaphragm wall technology, Jintai Grab became the first brand in the industry; At the same time, multi-axis drilling rigs are growing rapidly in soft soil foundation markets such as Jiangsu, Zhejiang and Shanghai, and Jintai ZKD series multi-axis drilling rigs have become the mainstream brand of SMW construction method products in the market. In 2010, Jintai introduced SH30H large triangular medium-sized rotary drilling classic model. Since then, it has become the benchmark product of the industry in Guangdong with its obvious advantages of strong rock penetration ability and high reliability.
2012-2021 is the "golden decade" of construction machinery. With the acceleration of national infrastructure investment, the construction of urban rail transit and three-dimensional transportation hub, the implementation of national expressway and high-speed railway network strategy, the hot spots of super projects such as Hong Kong-Zhuhai-Macao Bridge, Sichuan-Tibet Railway, water resources project in the Pearl River Delta, and the Yellow River East Diversion, etc ......................................................... Based on the user's value, Jintai continuously iteratively upgraded the rotary digging and grab products. At the same time, it began to research and develop the double-wheel milling, double-wheel stirring and customized piling machinery products that meet various construction methods, and the whole series of piling machinery products and applications have developed by leaps and bounds.
Rotary drilling rig (multifunctional drilling rig)
The model has been expanded from the initial 10-ton rice minicomputer to the 60-ton rice super-large machine. Jintai's deep underground drilling technology and professional quality spirit have created the market reputation of Jintai rotary drilling rig with "strong power, sturdy and durable, high efficiency and energy saving".
Wall grab
The sales volume has maintained the leading position in the industry for more than 10 years, constantly challenging the extreme depth. In 2020, SG100 grab "Big Mac" will be released offline. More than 200 Jintai continuous wall grapples participated in the construction of supporting projects of Hangzhou Asian Games, and super projects such as Beijing Sub-center and Wuhan Yangtze River Center were also concentrated on stage. Jintai grapples can be seen everywhere in the national subway projects.
Double wheel milling
Grind a sword for ten years. Jintai takes a unique approach, adopts air-lift reverse circulation slag discharge, and simply switches with Jintai grab to realize the multi-purpose function of one machine. In 2013, it first appeared in the foundation pit project of Hangzhou International Convention and Exhibition Center, creating a precedent of double-wheel milling national brand. In 2017, Xujiahui Center Project, the first high-rise building in Puxi, Shanghai, competed with international brands on the same stage, and the 77-meter milling technology became famous in World War I, which ignited the enthusiasm of domestic construction machinery head manufacturers to develop double-wheel milling products. In May 2018, the key node project of china huadian hotspot project-the 76-meter deep well project crossing the Yellow River was completed. In 2019, it entered the Pearl River water resources management project and conquered the deepest groove section of 77.6 meters. The efficiency and energy consumption ratio exceeded that of international brand products, and it won 8 bids in two years. In 2021, Jintai SX50 double-wheel milling successfully challenged the ultra-deep groove of 120 meters in the national key water conservancy project in Tibetan areas, demonstrating the power of national brands.
Hydraulic milling stirring drill (double-wheel stirring)
It was officially launched in 2014, breaking through international technical barriers, and quickly forming a series product portfolio with China's working conditions and user needs. It has two power modes of diesel and plug-in, and two series products of walking and crawler chassis. It has been tested by more than 200 projects in more than 20 provinces and regions across the country, and won the second prize of National Science and Technology Progress Award in 2017.
Multi-axis drilling rig
Multi-axis mixing drilling rig was introduced to China by Jintai Co., Ltd. in the late 1990s, and it became one of the mainstream products of pile driver family through adaptive transformation. This product has been widely used in the Chinese market for many years, with mature construction method, stable market demand and low entry threshold. Jintai upgraded the existing products to more than double the construction efficiency, and implanted an intelligent grouting system to ensure the quality of mixing wall.
Multifunctional expansion
In view of the characteristics of basic construction industry and diversified needs of customers, Jintai attaches great importance to the multi-functional expansion of products in product development, which fully reflects Jintai's profound technical background and professionalism in the field of pile machinery subdivision. First, one machine is multi-purpose: function switching between rotary digging and double-wheel milling, function switching between rotary digging and double-wheel stirring; Switch between grab bucket and double-wheel milling function. Secondly, a main engine can be equipped with different working devices to realize various construction methods: BZ pile frame can be equipped with multi-axis drilling machine, double-wheel stirring machine and full pipe drilling machine; The main rotary excavator can be equipped with hydraulic hammer, down-the-hole hammer, long screw, vibrating gravel pile, etc. The multi-functional expansion features of Jintai products are no longer conceptual products, and each function has a successful application and verification case.
