The xingyan expressway is an important infrastructure for the 2022 Beijing winter Olympics. For help, the 2022 winter Olympics in the construction of the project, gram lei trowel (Kleemann) mobile reaction type crushing and sieving equipment joint operations, frantic jumble creatively to tunnel hole processing for the high quality raw materials, not only make full use of the natural resources, save transportation and solid waste treatment of huge fees, also ensures that the construction of environmental protection, harvest the amazing good effect.

The lei trowel-mobile crushing and screening equipment ensures shorter transport routes because their tracked chassis allows access to rock mining sites or near tunnels

project details

The xingyan expressway is an ambitious new project with four lanes and a length of more than 42 km. The new section will connect the sixth ring road in northwest Beijing with yanqing district, home to the national alpine skiing center and the xiaohaituo national sleigh and snowmobile center. Therefore, the construction project of xingyan expressway is the key guarantee project for the 2022 winter Olympic Games.

excellent construction scheme: highway material from tunnel ballast

The contractor, China railway construction corporation limited (CRCC), won the contract to build the changping district section (highway section III) through which the project will pass. The biggest challenge facing the construction of this section is to build a 3.5km long double-hole tunnel. & ndash; Two tunnels up and down. To the high praise of the team on site, the obstacles that stand in the way not only do not generate disposal costs, but also make a profit. The key is the crewel MR 130 Z EVO 2 mobile counterattack crusher. It processes tunnel ballast into new aggregate for the construction of highways.

By means of easy transportation and tracked chassis, mobile lei trotfloat equipment can be recycled in the field to effectively protect resources and reduce costs

The excellent project of using tunnel ballast as raw material for expressway has achieved excellent results. Tunnel materials are recycled efficiently, eliminating the significant cost of disposing of them. At the same time, the amount of stone extracted from quarries is reduced, and natural resources are more fully and efficiently utilized. In addition, material processing on site not only reduces transportation costs, but also reduces the exhaust emissions of trucks, thus ensuring the environmental protection of construction.

recycling of finished products

0/10 mm particle size: it can be used as grouting for the tunnel body of baiyanggou tunnel on xingyan expressway in changping district, Beijing

10 & ndash; 31.5 mm particle size: can produce concrete, used for the construction of xingyan expressway lane

efficient regeneration construction

Recycled tunnel ballast can achieve two main objectives: resource conservation and cost savings. Regeneration plays an important role in CRCC's projects. Lei lei trowel technology to provide valuable support. Most of the material, 300,000 m³ Limestone is processed near the tunnel site. It also makes construction more efficient and economical. In short, shorter journeys mean fewer trucks, lower fuel consumption and less emissions. Once at the construction site, the stone is removed by the construction vehicle and fed by the excavator to the MOBIREX mobile counterattack crusher. After the crushing process, the material will be transferred by MR 130 Z EVO 2 to the MOBISCREEN MS 19 D triple screening facility. Finally, four finished products can be produced, with the output up to 230 t/h. The unit equipment has a huge power reserve, and the throughput of the whole equipment can reach twice the average output.

Versatile, easy to transport, short setup time, higher equipment readiness: this is the MOBIREX EVO 2 series mobile counter crushing device

MOBIREX 130 Z EVO 2 counterattack crusher highlights
Ideal material flow: the material channel gradually amplifies in the direction of material flow, eliminating the risk of material blockage

Transport and mobility: smooth loading thanks to greater ground clearance

Security and user friendliness: all operational components are easily accessible

Sustainability and recognition: the ideal solution for environmentally friendly construction
