“Fill-filled” is a common trick in domestic infrastructure. It is incredible that this trick is now used in national-level key PV projects. How is the chain of interest behind this? It is subject to thorough investigation by the regulatory authorities.
The “National Key PV Project” actually encountered “Li Gui” at the beginning of the construction, and the project construction unit and the supply unit turned out to be a family. What kind of interest chain is hidden behind the operation of the rules?
The Shanghai Stock Exchange reporter recently investigated two "photovoltaic front-runner technology project bases" in Shandong, and found that the piles on the project's infrastructure site clearly harbored the heart of the A-pillar, but were put on the gorgeous coat of the AB pile. Some senior industry insiders said that these shoddy acts will lay a major safety hazard to the project. "If you encounter bad weather, it will probably lead to complete damage to the structure, and not only economic losses, but also economic losses. It may also cause a safety incident."

In the table, not all the underlying steel bars accidentally "slimmed down"
The National Energy Administration approved eight “photovoltaic front-runner technology project bases” last year, and Shandong has won two project bases, which are located in two coal mining subsidence areas in Jining and Xintai.
According to the data, Hong Kong-listed company Beijing-controlled clean energy has become a successful bidder for the National Advanced Technology Photovoltaic Demonstration Base Project in Xintai Mining Subsidence Area after several rounds of competition. According to the disclosure, the total investment of the project is 820 million yuan. The company's total investment in photovoltaic projects in Weishan County, Jining City reached 520 million yuan.
What is surprising is that such a heavy investment project has hidden "Li Gui" in the infrastructure sector.
Shandong Yuzhen is one of the locations of the “Photovoltaic Runners” project in Xintai City. After several inquiries, the Shanghai Securities Journal reporter finally came to the site of the Beijing-based Xintai 100MW Agricultural Light Complementary Runner Project site. The land in the subsidence area of ​​the old coal mine has long been After re-finishing, the entire project site was blocked by barbed wire. After walking through a muddy path, the reporter saw the signboard indicating the name of the project. In the depths of the road, there were several farmers who lived here.
At the construction site, a large number of pipe piles bearing the "Hercules" signboard were piled up on the construction site, but the reporter did not see too many workers to work. The only two piling drilling equipments were also idle near a pile of pipe piles. The supervisor was chatting at the side. "Turning over the village, a large piece of land there is also this project, and it has not yet started." The workers at the scene pointed to the front. "I just started work. Today, there is something wrong with the equipment. Now I mainly deal with the land and piling. As for the infrastructure work, just like building a house, the foundation is laid." The supervisor on the spot said so.
The reporter's bidding document for obtaining the project shows that PHC300-AB-70-7 is the main type of pipe pile that was signed in the project. Pipe piles are commonly referred to as cement columns with steel bars. PHC stands for pipe pile types, 300 and 70 are outer diameter sizes and wall thicknesses, 7 is the length of the pipe pile, and AB is the most critical parameter for the entire pipe pile— - Effective pre-stress value, generally speaking, is the steel content. According to this classification, the pipe pile is divided into four types: AB type, A type, B type and C type, and the bearing capacity is gradually lowered. In addition to the above-mentioned model pipe piles, PHC400-B-95-7 is also the type of pipe pile used in the project drawings.
"This should be the A pile (material), but it was sprayed into the AB pile (mark)." An industry insider asked the reporter to make such a judgment to the reporter after the on-site inspection. “The steel bars in the A pile should be around 7mm, and the AB piles should be 9.0mm. Because of the different thickness, the A pile has lower bending, shearing and tensile bearing capacity than the AB pile.” The person further explained.
The reporters from the Shanghai Stock Exchange reported that the PHC300-A-70-7 and PHC300-AB-70-7 tube piles are very similar in appearance, and it is easy to mix the beads. The main difference between the two is internal reinforcement and pile bearing capacity. The most convenient and effective method of identification is to measure the diameter of the steel bar.
In order to prevent visual misjudgment, the reporter found a tape measure to measure the diameter of the steel bar exposed by the cross section of the pipe pile in the project site. Because the steel bar is not a standard cylinder, the reporter uses the maximum diameter as the reference standard. The maximum diameter of the steel bars exposed by the piles scattered in the project base is about 7mm, and the minimum is only 5mm, while the diameter of the pipe pile of the PHC300*70AB model is Should be around 9mm.
The measurement results show that the actual material of the pipe pile on the construction site is obviously inconsistent with its surface marking.
“The type of pipe pile used is mainly determined by the above bearing capacity and soil environment. The same photovoltaic panels are carried by low-grade pipe piles, and the service life will be greatly shortened.” The above-mentioned insiders said: “The main performance is in wind and pressure resistance. In terms of performance, the content of steel bars is low, and it is prone to dumping or fracture."

Stealing the beam to change the column A pile to change the label "upgrade"
The piles on the construction site clearly harbor the heart of the A pile, but they are covered with the gorgeous coat of the AB pile.
From a distance, the pipe piles printed on the site with the logo of "Hercules" are no different from the pipe piles of other construction sites. A considerable part of the pipe piles have already penetrated the surface. However, after the reporter approached, the fuzzy model logo on the pipe pile caught the attention of the reporter. The PHC300-AB-70-7 handwriting printing of the first half of the production enterprises, batches and models indicated on the pipe piles is very neat, but the keyword “AB” is ambiguous, and the font and size are also clearly different from the printed words. The reporter gently wiped the word "AB" with his finger, and the finger was covered with black pigment. The reporter used the same strength to wipe other printed words, but there was no discoloration.
A pipe pile with such a vision is not an isolated case. The reporter traveled throughout the project site, and the pipe pile logo almost all had the above problems.
In addition to this type of unclear pipe pile, the reporter also found on the construction site that many pipe piles did not print the effective pre-stressing stress value at all, and some pipe pile models even had traces of smearing.
The "10G409 Prestressed Pipe Pile Atlas" published by China Building Standard Design and Research Institute indicates that the outer surface of the pile body should be marked at the distance of 1000mm-1500mm from the end. The mark includes the name of the manufacturer, the name of the pipe pile, the date of manufacture, The pipe pile number and the qualified mark shall, according to the above-mentioned documents, the pipe pile markings shall clearly record the key parameters such as pipe pile type, outer diameter size, wall thickness and steel content.
"According to the national production requirements, the model identification must not be missed, and most of the domestic production equipment is also designed according to this standard." Insiders told reporters.
"This is definitely not a machine printing. The two characters of AB should be printed at the later stage." The reporter handed over the photos and other materials on the spot to the person in charge of a printing factory in Shandong. The person judged this. "You see, this is basically two parts. The font and font size are different, and this is not a printed material. The two characters AB should be printed with toner in the later stage. Other characters should be used in production. Ink printing."
Is this a rule or is it tricky?
The reporter then visited the construction site of several other projects in the PV front runner program in Shandong. The investigation found that, except for the pipe piles printed on the site marked with the "Hercules" logo, the pipe pile marks on other sites were basically visible, sprayed once, and wiped with fingers.
From this, it can be judged that Jiangsu Hercules Pipe Pile Co., Ltd. has used the "Tiger Cat for Prince" trick to use the "Gorgeous Outerwear" to "change the upgrade".

More than 800 million PV projects with safety hazards
National key projects have encountered "Li Gui" in the infrastructure construction stage. Who is so daring?
According to the official website of the Shandong Development and Reform Commission, the “Photovoltaic Runner” project is a key project identified by the National Photovoltaic Power Generation Construction Plan in 2016. The project will play an important role in demonstrating and leading the comprehensive management of coal mining subsidence areas in Shandong Province.
The reporter found that the owner of some projects in Xintai area is Beijing Enterprises Clean Energy Group Co., Ltd., and the general contractor is China Power Construction (8.200, 0.01, 0.12%) Group Guizhou Engineering Company. The construction unit is Jiangsu Wanqiang Geotechnical Engineering. Ltd., the supplier is Jiangsu Hercules Pipe Pile Co., Ltd., the latter two are affiliated to Jiangsu Zhongneng Group. The project is expected to use a total of 160,000 meters of PHC300-AB-70-7 pipe piles.
According to the reporter's inquiry, the market price of the AB pile type that should be used in the above project is about 90 yuan/meter, while the A pile type actually used in the construction has a market price of about 75 yuan/meter.
This is about 17% of the price difference, who is in the pocket? The risk geometry behind it?
An anonymous person who had participated in the bidding of the project told the Shanghai Securities Journal that the reason why the company was able to win the bid was because its offer was low. "This is definitely a low cost. When bidding, we are in the price, but the quality is completely unprotected. In bad weather, it is likely to cause complete damage to the structure. It is not just economic loss. It will also cause a security incident." The person is so sighed.
The Shanghai Stock Exchange reporter found that the project's supplier unit, Jiangsu Hercules Pipe Pile Co., Ltd. and the construction unit Jiangsu Wanqiang Geotechnical Engineering Co., Ltd. are all subsidiaries of Jiangsu Zhongneng Group.
“The construction party and the supplier are both family members. It is easy to get tricky during the construction process. It is also easier to pass the inspection when it is finally accepted.” A long-term construction manager of Party B analyzed to reporters, “When the key projects are being constructed, Generally, in order to avoid suspicion, the vast majority of the construction party and the supplier will find irrelevant enterprises and work together."
As of the date of the press release, the reporter repeatedly called the owner of the North Control Clean Energy, hoping to reflect the problems found in the investigation, but failed to get in touch with them.
“Fill-filled” is a common trick in domestic infrastructure. It is incredible that this trick is now used in national-level key PV projects. How is the chain of interest behind this? It is subject to thorough investigation by the regulatory authorities.
