The expansion of the MTR Hung Hom Station was involved in engineering scandals in the past, and the new platform was finally officially opened today (20th).

Pan Zhuohong, the managing director of Zhongke Xingye, a subcontractor involved in the Hung Hom station project, criticized the platform for not completing leaks after inspecting the new platform this afternoon, and the track position of the platform towards Wuxisha in the future will be more There is obvious stagnant water, and it is suspected that the continuous wall construction is poor and the water seepage problem is not solved. In addition to increasing maintenance costs in the future, the life of the Hung Hom Station may not be as long as 120 years as expected.

Pan Zhuohong also suspects that the exhaust gas suction grooves above the rails are not equipped with dampers (damper). Once a train fires, it may affect the ventilation capacity and endanger the safety of passengers. He said that there is a position above the rail that does not completely cover the steel bars and is only coated with rust prevention. Oil, the appearance of steel bars is still faintly visible; there are also rust marks on the platform floor, which is suspected to be caused by past dripping rusty water.

He criticized that despite the two-year delay in launching the platform, the situation still failed. "I don't think everyone in the class has passed. The management of the MTR is simply ineffective."

Pan Zhuohong: Water leaks in 60% of the track towards Wuxisha Station

The Hung Hom Station project has repeatedly been involved in engineering scandals, such as shortening of steel bars, loss of a large number of engineering records, unauthorized design changes, etc. Due to various problems, the Tuen Ma Line could not be opened to traffic as scheduled. Last year, it could only be opened to Kai Tak Station in sections , And finally postponed to next Sunday (27th) the opening of the entire Tuen Ma Line. Today, the new platform of the Tuen Ma Line at Hung Hom Station will be opened first.

In the past, Pan Zhuohong was regarded as the "whistleblower" of engineering scandals. He visited the new platform of Hung Hom Station this afternoon. He returned to the starting point of the engineering scandal that day and pointed out a number of unresolved problems.

Leaking sea water can cause steel bars to rust and concrete flaking

Pan pointed out that there are obvious water leakage problems in the track area towards Wuxisha Station. It is visually observed that 60% of the places are leaking, and there is obvious water accumulation.

He explained that the proximity of Hung Hom to the sea meant that the water level was high. However, the continuous wall of Hung Hom Station was poorly crafted. Cracks had been witnessed in the past, and as a result, groundwater entered the station through the cracks.

He bluntly said that the related problems are difficult to solve. Although it may not directly cause the accident, the seawater is salty water, the steel bars are prone to rust, and then expand, causing the concrete to peel off, pushing up maintenance costs, and shortening the life of the station, which may not reach the target 120 years .

Insufficient damper of ceiling exhaust gas suction slot affects ventilation

In addition to the water seepage problem, Pan Zhuohong observed the position of the ceiling on the rail pair and found that the rail ceiling exhaust gas suction trough was not equipped with a damper (damper), which may affect the ventilation system.

He explained that in the event of a train fire, the exhaust gas suction slot will suck exhaust gas. The function of the damper is to make the equipment exhaust in a single direction. Once it is not installed, some of the exhaust gas may not be removed, posing a certain danger. Tie should explain whether there is a new design.

The ceiling is not fully covered and cracks appear

At a location close to the exhaust gas suction groove of the rail ceiling, Pan Zhuohong found on the platform towards Wuxisha that the steel bars in one area were not completely covered, but only coated with anti-rust oil. If you look closely, some concrete excrement has even a few cracks. "Obviously there are steel bars without a cover, that is, the steel bars are stuck with the concrete surface, so that the shape of the steel bars is laid out, like a grid of tofu."

In one place, the steel bars were not completely covered, and only anti-rust oil was applied, which resulted in the appearance of the shape of the steel bars.

At the platform, Pan Zhuohong found that some of the floor tiles were of different colors, or even rust marks appeared.

He estimated that some artificial stone bricks were stained before, and the color changed after being washed with detergent; in addition, rust water may drip from the ceiling in some locations and seep into the stone bricks. Once relevant conditions occur, they cannot be repaired. He believes that the contractor Responsible for replacement, MTR "should not accept the goods."

In addition to more serious engineering problems, Pan Zhuohong also found other problems in the escalator.

He pointed out that the adjacent glass should be pasted with adhesive strips to prevent the glasses from directly colliding with each other when they expand; however, the adhesive strips are not all pasted at present, or some of them have become loose.

One of the lines was seen at the scene.

Poon Zhuo-hung criticized the quality as not satisfactory. MTR spent two years repairing it, but failed to complete the omissions. Well, I don’t think everyone in the class is up to the standard, and the MTR management is simply ineffective.” He believes that after taking office, MTR Chief Executive Kan Zepei failed to perform the omission work, describing his management as “completely inaccessible” and said Two years since the appearance of the scandal, no one has been held legally responsible and disappointed.

The police went to Hung Hom Station to search for evidence on engineering issues.

Pan Zhuohong expects that for the cross-sea platform of the Zuhom Station to be opened next year, engineering problems such as water seepage will be more serious, and he will witness more traces of repairs and understand the reinforcement situation.
