Hainan 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 on the direct effect of the site together with the body, the maximum possible recovery of the original shape of the 200 000 years ago.

The program of "minimum conceal and eliminate hidden dangers, into natural" design principle, to be built in the ape-man hole cover an area of ​​3,700 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 required to cover the minimum area and height volume designed to minimize the intervention of the body sites, isolated rain, snow, hail, sun design by overlapping the inner and outer layers of the roof, etc. the direct effect of natural factors on the ruins of the body, of the ape-man hole in the effective maintenance together to ensure that the architectural design and ruins the environment.

It is understood that the project is expected to complete by the end of 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 inside the core area of ​​the ape-man, can not be destroyed during the construction site of the body, so the site layout is limited.

2. The construction site environment is complex.

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

3. The installation of steel structures and welding difficult.

Maintenance shed a single layer lattice shell structure, complex modeling, slope, span, welding capacity, installation and welding of steel structures demanding.

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. Hainan Steel

■ Introduction

Zhoukoudian cave ape's heart, and found about 40 representatives of "Peking Man" individual nearly 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 to be dug by etching has collapsed." Site Management Office official said that since the twenties of the last century, dig, ape hole subjected to prolonged sun, rain, erosion and other natural forces of destruction, and therefore, from 2009 onwards, according to the geological conditions and diseases expert opinions, the cultural relics department and the Chinese Academy of Vertebrate Paleontology and Paleoanthropology jointly ape Western sectional hole dug to carry out maintenance of the clean-up operation, launched together Ape Man Cave maintain the Competition proved.

Tsinghua University Architecture Design Institute designed "Zhoukoudian first place (ape holes) maintenance building design plan" has been approved by the UNESCO World Heritage Centre and the National Heritage Board in 2013. Hainan Steel
