Guangzhou Steel news: the Zhoukoudian cave ape started "plus top"

 

Yesterday, the Zhoukoudian cave in the heart of the ape-man maintenance shed officially started construction. The maintenance shed in isolated rain, snow, hail, sun and other natural factors direct effect on the body at the same time the site will be possible to recover up to 20 million years ago, the original form.

The program of "minimum cover, to eliminate hidden dangers, with nature," the planning principles, to be built in the ape-man hole covers an area of ​​more than 3700 square meters of the maintenance shed. Maintenance shed span of 77.5 meters from north to south, east-west span of 54.5 meters and a maximum height of 35.7 meters, the use of space monolayer shells steel.

Site Management Office official said, the maintenance shed is the minimum required coverage area and height volume planning, site of the body in order to minimize interference, isolated rain, snow, hail, sunshine through the outer and inner layers of the roof build-planning, etc. the direct effect of natural factors on the ruins of the body, of the ape-man hole in the effective maintenance, while ensuring construction planning and site environment harmony.

It is understood that the project is expected to end in late 2016. Pre-engineering will not cause too much impact on the visit, the site will divide the late opening hours.

According to reports, in order to make the Zhoukoudian site surrounding environment has been improved, the site perimeter has closed, shutting down the site surrounding nine cement plants, 11 shaft kiln production lines, 40 non-coal mines, 13 coal mines and other pollution and destruction of the natural environment industrial and mining enterprises, governance of the Zhoukoudian River and surrounding abandoned mines, planting more than 1,000 acres.

■ Difficulties

1. Steel site construction is limited.

The construction site is located in the core area of ​​the ape-man cave, in the construction process does not destroy the ruins of the body, so the site layout is limited.

2. messy construction site environment.

Ape cave dense vegetation, narrow passageways, restricted construction conditions, lifting machinery is arranged with a certain degree of difficulty.

3. steel equipment and welding difficult.

Maintenance shed a single layer lattice shell structure, shape messy, slope, span, welding capacity, equipment and welding of steel structures request high.

The steel construction strict security measures.

As the construction site is located in the mountain below the maximum network shell drop of more than 30 meters, so the construction safety particularly high fall and fire will be among the control points of the project.

■ Introduction

Zhoukoudian cave ape's heart, and found about 40 representatives of "Peking Man," an individual close to 200 human fossils, more than one hundred thousand pieces of stone tools, several layers of ash and hundreds of kinds of animal fossils, is the most scientific value of the site iconic accumulation body, preserved ruins of the most complete stratigraphic sequence and the wealth of scientific information.

"200,000 years ago, there is a natural ceiling, but after the collapse when corrosion is now to be discovered." Site Management Office official said that since the twenties to explore, ape cave long suffered from sun, rain wind erosion and other natural forces of destruction, and therefore, from 2009 onwards, the joint to ape the West sectional hole excavations carried out maintenance work to clean up the disease according to the geological conditions and expert opinions, the cultural relics department and the Chinese Academy of Vertebrate Paleontology and Paleoanthropology, and start the Ape Man Cave collection maintenance plan, argument.

Tsinghua University Architecture Planning Institute Planning "Zhoukoudian first place (ape hole) Maintenance Plan Building Plan" was approved by the UNESCO World Heritage Centre and the National Heritage Board in 2013. Guangzhou Steel
