More than 500 Sany equipment to build the Jakarta-Bandung high-speed railway, "the whole railway is SANY"

Recently, with the roar of the Sany excavator, the No. 3 tunnel of the Jakarta-Bandung high-speed railway has been successfully broken through, taking a key step towards the goal of completion and opening to traffic. Currently, in this"The people of the two countries are concerned, and the leaders of the two countries are concerned"On the project, there are more than 500 Sany equipment waving the "iron arm" to promote the project progress at full speed.

80% of them are Sany equipment

The Jakarta-Bandung high-speed rail project was personally confirmed and directly promoted by the leaders of China and Indonesia.The high-speed railway, which connects Indonesia's capital Jakarta and Bandung, has a total investment of about US$6 billion, a total length of about 142 kilometers, and a design speed of 350 kilometers per hour.

The project is the "first order" for China's high-speed rail system, all factors and the whole production chain to go abroadIt is also an important landmark project of the Belt and Road Initiative between China and Indonesia.

When the project started in 2016, President Xi Jinping wrote in a congratulatory letter to Indonesian President Joko Widodo, "The successful implementation of the Jakarta-Bandung high-speed rail project has set a new record for China-Indonesia practical cooperation, and will set a new benchmark for cooperation between the two countries in various fields, especially in the fields of infrastructure and production capacity."

In the past five years, as the most important "partner" of Chinese builders, countless "SANY" large-scale equipment has been brought to the project site - Java Island.

According to statistics,At the peak of construction, Sany had more than 500 large-scale equipment in service hereIncluding more than 150 excavators, more than 60 rotary drilling drills, more than 50 cranes, more than 150 mixer trucks, more than 20 sets of mixing plants and more than 30 pump truck trailer pumps, etc., responsible for the whole line of earthwork and tunnel operations, concrete transportation and pumping, cast-in-place piles and hoisting construction.

Liu Haitao, the person in charge of the largest subcontractor of the Jakarta-Bandung high-speed railway, said that at present, the vast majority of the construction lines of the entire Jakarta-Bandung high-speed railway are Sany equipment."Its main construction equipment occupies more than 80%."

Made in China "touchstone"

The Jakarta-Bandung high-speed railway is also a "touchstone" to test the quality of China's manufacturing in the sea.

It is located in the world's most active "volcanic earthquake zone", adjacent to the equator, with high temperatures and rainy seasons, and the annual construction time is only more than 6 months, and the population density of the island has reached 1045 people/km², and the construction environment is extremely complex.

Under the strong concern of the people,"If the quality of a place is not up to par, the reputation will collapse."This is the consensus of all the participants.

The foundation of the Dekarur EMU is being built

Decarur EMU is the only place for high-speed rail vehicles to park and maintain on the whole line.Underground is a layer of silt 25 meters thick。 After a number of Sany excavators, rotary drilling rigs, pump trucks and other foundation construction and pipe pile operations, its land bearing capacity has been greatly improved. At the end of August this year, the first building of the EMU was successfully capped.

The extremely challenging Tunnel No. 5 has poor clay soil self-stability and staggered bridges and tunnels at the exit, so it cannot be constructed by drilling and blasting, and can only be excavated slowly by excavators. Sany SY215C took on the heavy responsibility and ensured that the project was completed on schedule in March this year.It is reported that the Jakarta-Bandung project has a total of 13 tunnel sections, of which 11 are excavated by Sany excavators.

The rock formation of Tunnel 11 is as hard as 120MPa, which cannot be handled by conventional equipment. For this reason, the construction party specially procuredThe largest TBM in Indonesia - Sany STR318H TBM。 A few days ago, this dozens of tons of big guy has arrived in Jakarta and is preparing to enter the site for construction.

Recognized as the most difficult bridge No. 2With a total length of about 35.7 kilometers and a continuous beam length of 213.8 meters, it spans two expressways and an overpass, and the working surface is narrow. In this regard, the construction party adopts the cantilever hanging basket method for the main span of the continuous beam, and the side span adopts the cast-in-place method of the bracket, which solves the problem.

It is worth mentioning thatIn the 5 years since the start of the project, nearly 200 sets of Sany concrete equipment monthly comprehensive attendance rate of more than 98%,Lost time and rework due to failure is 0to set a new record in the local industry.

At present, with the help of large-scale equipment, all 22 control projects of the Jakarta-Bandung high-speed railway have made breakthroughs and officially entered the stage of comprehensive box girder erection.

The pride of the two peoples

Indonesia's traffic is relatively backward, Jakarta is about 150 kilometers from Bandung, and the traffic jam is very serious. In order to ensure the quality of service, Sany has established 3 service outlets along the project according to the construction progress, with 15 service engineers stationed and equipped with 5 special service vehicles.

During the 5-year construction period,The Indonesian people have a heartfelt affection for the quality of China's equipment and the conscientious and responsible spirit of Chinese engineers.

During the epidemic in June, customers will:firstThe new process is used to pour long-span continuous beams. After receiving the call, Sany engineer Liu Jun immediately rushed to the scene with enough accessories, and moved to the construction site for food and accommodation. Under his watch day and night,The whole concrete was poured in one time within 48 hours, reducing the cost of 3 million yuan for the customer and saving the construction period of 7 days.

"At first, Indonesians thought Trinity was crazy, and they didn't work day or night." Liu Jun said, "Later, the professionalism of the Chinese infected them. ”

At present, the Jakarta-Bandung high-speed railway has become a window for local people to understand China and Sany. Liang Jing, marketing director of Indonesia, said, "Everywhere the project goes, people from nearby villages are vying to come to work on the construction site.In their spare time, many of them will learn to drive Sany's excavators and cranes, because after learning, they can get higher remuneration.”

It is estimated that in the past five years, the high-speed rail construction site school opened by the construction party China Railway has trained nearly 100 local operators with Sany equipment as teaching aids.

Lini Sumarno, then Indonesia's Minister of State-Owned Enterprises, highly praised the Jakarta-Bandung high-speed rail project:"The Jakarta-Bandung high-speed railway is a symbol of friendship between Indonesia and China, a 'common pride of the two peoples', and will definitely become a model of cooperation between Asian countries."

Today, on both sides of the high-speed railway, the roar of machinery is playing the song of friendship between the two peoples.
