A few days ago, XCMG foundation and leading enterprises and industry experts in the field of foundation construction in Shanghai gathered together to witness the milestone moment of domestic double wheel milling - XCMG double ringing slotter high precision sleeve milling groove achievement release. XCMG's double wheel milling groove accuracy is 1 / 1000, and many properties such as load-bearing, soil retaining, water interception and seepage prevention are further improved.

"I have a new understanding of domestic brands"

Shanghai beiheng passage is the first long underground passage across the city center in complex environment in China, and also the second artery in east-west direction of Shanghai. The double ringing slotter high-precision grooving is the construction feedback of this super project.

The stratum in Shanghai is soft, and most of the projects are constructed in deep trench with the depth of more than 70 meters. Only the verticality with the error less than 2 / 1000 can effectively ensure the anti-seepage of the wall. At present, the domestic double ringing slotter has never been successfully applied in Shanghai area in the North Cross Passage Project of XCMG. This construction is the key step for XCMG to rectify the name of domestic equipment.

Facing the construction environment of complex stratum and residential area, XCMG double ringing slotter xtc100 / 105 has successfully completed the sleeve milling construction of nine 75m deep grooves. The vertical accuracy has reached 1 / 1000 level, exceeding the industry standard, and fully reaching the highest standard of the world's leading products. XCMG has proved that it is feasible to make in China with its high accuracy!

After more than a month's use, the project side of beiheng channel also sincerely sighed: "we also entered XCMG equipment with a try mentality, and now we have a new understanding of domestic brands. XCMG double wheel groove milling machine construction efficiency and precision and industry leading brand groove milling machine, but in terms of cost performance to be far ahead! This makes more Shanghai construction companies see the feasibility and credibility of domestic equipment, and China's future ultra deep underground construction will no longer rely on imported products! "

"Take off this pearl and give it to you"

With the emergence of the upsurge of underground space development, the working condition of driving tens of meters or even hundreds of meters underground has become the norm, but the realization of the maximization of anti-seepage, retaining and other functions still depends on super equipment such as double ringing slotter.

The double ringing slotter has many advantages, such as short construction time, high efficiency, high construction precision and strong anti-seepage ability, but there is also a problem behind it - the core technology is monopolized by foreign countries, and the price is expensive. It is not only the "apple of the palm" of the piling machinery, but also the "luxury" worthy of the name. However, the key technology can not be obtained or bought. XCMG continued to increase R & D investment and overcome difficulties one by one, and finally launched the first domestic independent technology double ringing slotter xtc80 in 2015.

A series of new products such as xtc180 double ringing slotter, the "world's first milling machine", have been launched successively. In less than five years, XCMG's double ringing slotter has occupied half of the Chinese market. With the technology becoming more and more mature, XCMG's double ringing slotter also began to go abroad. Xtc80 / 85 is exported to Malaysia and Singapore, realizing the feedback from "importing" to "going out"; xtc8060m low clearance double wheel groove milling machine opens the customized development road.

The release of XCMG double ringing slotter high-precision grooving results makes many construction enterprises realize the advantages and feasibility of double ringing slotter in ultra deep continuous wall construction. XCMG double ringing slotter will participate in continuous wall construction of various projects with high-precision guarantee of anti-seepage and load-bearing, and help the construction of China's future underground city.Editor/Serena
