Linlin Expressway is an expressway from Linzi to Linyi Yinan in Shandong Province.，It is also the longest expressway project under construction in Shandong Province.，This road is Shandong.“Nine vertical lines, five horizontal lines, one ring, seven shooting lines and many links”An important part of the highway network。To the north of the project is the proposed Binzhou Zhanhua-Linzi expressway.，South to Rilan Expressway，After completion，It has become a high-speed corridor running through the north and south of Shandong Province.。The total length of the main line is 192.64 kilometers，The total investment is 370.4.2 billion yuan，Design speed 120 kilometers per hour/Hour，South to Rilan Expressway。Via Zibo、Linyi。It passes through Zhangdian District of Zibo City、Linzi District、Zichuan district、Boshan district、Yiyuan County and Yishui County of Linyi City、Yinan County and other two cities、9 districts and counties、26 townships、263 villages，The section from the starting point to Qinglan Expressway is a two-way six-lane road.，The rest are two-way four-lane.。So far，Subgrade works of the project have been completed 18%，Bridge works completed 20.5%，Tunnel works completed 16.4%。The project passes through the Heitieshan Scenic Area.、Lushan scenic spot、Red Revolutionary Base Yimeng Mountain, etc.，After completion and opening to traffic，It will further strengthen the interconnection between Shandong Province and the Beijing-Tianjin-Hebei and Yangtze River Economic Belt.，To optimize and improve the layout of the provincial road network、It is of great significance to promote the integrated development of the economic circle in southern Shandong.。

Sida Hard Rock Treatment Technology Helps expressway Construction 

Xiao Da saw it at the construction site of the temporary expressway.，Workers are welding the base steel bar.，Several cranes are also working at heights at the same time.，The scene of construction is in full swing.。At another construction site with faster progress，Precast plate beam、Bridge deck pavement and other work are being carried out.。At the basalt sandstone disposal site not far from the construction site，Sida mobile crushing and screening equipment, which provides aggregates for the high-speed project, has entered the construction site.。

  

Basalt is repairing roads.、Railway、The best of the stones used for airport runways, etc.，Has strong pressure resistance、Crushing value is low、And that abrasion resistance is strong、Ood asphalt adhesiveness and the like，Always maintain a high position in the aggregate market。

A large amount of high-standard basalt gravel is needed for the construction of Linlin Expressway Project.，Three problems encountered in market procurement of high-standard basalt materials：First, the current supply of sand and gravel market can not meet the construction needs of the project quickly and efficiently.；Second, the market price of aggregate fluctuates greatly.，A large number of outsourcing purchases of aggregates increase the construction cost.；Third, the quality of aggregate supplied by the market can not meet the standard requirements of expressway paving construction.，The time cost of quality control is high.，The construction efficiency is reduced.。

There are a large number of mines in the project area.，Mining produces a large amount of tailings and offcuts.，These raw materials can only be stacked for a long time.，Causing a waste of land resources.、Destruction of ecological environment and other problems。Recycle limited resources，Integrate ecological construction into all aspects of economic development，In order to achieve circular development.，Really realize the win-win situation of social and economic benefits。

  

After comprehensive consideration of various factors, Shandong Road and Bridge Expressway Project Department，Decided to purchase basalt crushing and shaping production line，Use the surrounding ore、Ore resources produce high-standard stone materials in line with expressway and construction.。

Guangxi Sida Company relies on professional site application experience and its own excellent equipment technology，Combined with the investment situation of this project，Cost-effective tailor-made for customers、Use of flexible production processes，Highly recognized by customers。After several investigations,，The basalt mobile crushing and shaping production line of Guangxi Sida Company is selected.。The machine is manufactured by Stronda.SMHDAChina Service Team Delivery，Production runs 10 hours per day，Stable and efficient crushing ratio and lower power operating costs are the choice of customers.SMHDAThe main factor。

The design concept of Sida mobile crushing equipment is based on hard rock.，It has been focusing on hard rock crushing construction for many years.，It is recognized as an expert in hard rock treatment in the industry.。By strengthening the core technology,，Enabling moving line theory，Comprehensively radiating the crushing and screening treatment of materials in various fields。The production process of Sida hard rock treatment is mainly composed of Sida crawler mobile jaw crusher.S119J、Crawler mobile cone crusherHP300RS、Crawler mobile inclined screening machineS108，And a matched shape module、Digging machine、Composition of loader，Recently, the production and operation of the project at the high-speed construction site has been stable.。
