Since 2016, the 'yuntiandu' glass bridge in Zhangjiajie has been officially opened, becoming the world's first glass bridge in height and length at that time, bringing in 1.2 billion yuan of operating revenue, which is nearly five times of the total investment of 260 million yuan. Attracted by high profits, the glass trestle craze has spread rapidly in the past two or three years. Large and small scenic spots have to develop glass trestles or similar projects. At present, there are more than 2000 domestic projects such as glass suspension bridges, trestle roads and viewing platforms. Moreover, the scenic spot is no longer satisfied with the 'higher and more transparent' glass bridge, and has begun to pursue more 'frightening' glass projects. The early 'wanghong' glass trestle and glass suspension bridge have not caught up with the upstart like glass slide and 5D glass overpass in the past two years.
Many scenic spots are keen to build glass plank road
One of the reasons why glass trestle projects are popular is the sense of transparency of glass and the stimulation of natural landscape. But what is more frightening than the glass trestle itself is that there are no norms and acceptance standards in the industry, and even the regulatory authorities are unable to determine. Because, this may make the tourists who want to seek a moment of excitement really 'smash to pieces'.
Glass trestle projects, safety is the most basic bottom line. However, the current glass trestle industry seems to have entered a terrible vicious circle. With low construction threshold, low approval difficulty and 'huge profits', more and more scenic spots are invested in, and the pursuit of building higher and more transparent glass trestle projects has a more frightening effect, and has a greater attraction to tourists. At the same time, due to the lack of industry norms of acceptance standards, even the regulatory body can not be determined, which gives the "three noes" construction company a loophole.
In the East Taihang scenic area of Handan, Hebei Province, a glass plank road suddenly 'cracked', making tourists sweat. It is understood that 'Cracking' is a technical special effect, not a real cracking.
The glass trestle, which is higher, more transparent and more frightening, not only needs to be accepted according to the bridge standard, but also needs to consider the particularity of glass, geography, climate and other external factors. In the end, it may be built by a construction company that has no experience in road and Bridge construction, so the hidden danger will be greater. Originally, glass projects are more prone to accidents than ordinary projects. In the past two years, accidents and even human lives have occurred. Many regions are on guard against the risks of glass projects, but there are no standards and no competent departments, so they call it a halt. Since 2018, all 32 glass trestle projects in 25 scenic spots in Hebei Province have been closed, and many other provinces are also carrying out safety investigation and stopping high-risk projects. Once shut down, the profit margin will drop precipitously. In this case, the glass projects already in operation will be more frantic to "solicit customers" in order to make more money in a short time, and the negligence of maintenance and management may make the projects that are not very safe more dangerous.
It's not a healthy operation state to be afraid of problems or wait until problems arise. In fact, under the dual effects of windfall profits and regulatory vacuum, it's difficult for the glass trestle project to stop. Ensuring safety is the bottom line of glass trestle projects. To keep this bottom line, efforts should be made in construction design, daily maintenance and operation management.
Scared glass trestle, don't wait for human life to stop swimming naked
Glass trestle as a new thing, there is no unified national construction and acceptance standards, but all over the country has begun to study the local standards. To ensure the safety of the design is only the first step, daily maintenance and management level largely determines the safety of glass trestle projects. For example, the upper limit of the number of tourists to be received at the same time within the load-bearing range of the glass trestle, the level of extreme weather such as rainstorm or typhoon, the need to close the project, whether to prohibit the carrying of electronic products to reduce human risk, and so on, are all management norms that need to be considered. Whether it is to ensure construction safety or management compliance, under the premise of having standards, supervision should be in place to put an end to the current state that each department is in charge of its own. The establishment of competent departments is the first problem to be solved.
Glass trestle pursues "frightening", but the construction, operation and supervision of the project can not be frightening. How can tourists' life safety be trifled? To keep the safety bottom line of glass trestle projects, the state of supervision vacuum needs to end as soon as possible.
