By virtue of economy、Flexibility and efficient construction efficiency，Wirtgen side-laid slipform Paver has gradually replaced manual work and become the main force in the construction of small concrete structures.。
Recently, in the drainage ditch laying project of Yunnan old national highway reconstruction in the low mountainous area,，Although mountain roads have steep slopes and many bends,，The types of drainage ditches also include unconventional special-shaped large sizes.，SP 15 maintains excellent performance by successfully laying out the linear appearance.、Structural stability、Homogeneity、High-quality finished products with compactness meeting the design requirements。
What is more worth mentioning is that，SP 15 In this paving operation，In addition to the conventional baseline-guided paving method，Also by comparison with 3D Application of Digital Technology in Control System，Accurate paving without reference line is realized.。Through this digital solution，Slip-form paving can be achieved without the need for pre-piling、Setting out and removal reference line，The reference line also no longer obstructs work around the slipform Paver。Wider operating space for concrete Trucks and Excavators，This makes it easier and safer to transport materials to the slipform Paver。So，The whole process is more efficient、More economical。
Xiaowei will take you to understand the charm of Wittgen slipform paving technology through the video of the construction site on Yunnan National Highway.！

Case of working condition：
Project：Kunming is old 108 Kunming Section of National Highway Reconstruction
Location：Kunming Xilu Street
Application：Cement concrete special-shaped ditch pave by slip-form
Project challenges：The construction section of the old 108 National Highway in Kunming belongs to the mountain road.，The drainage ditch required by the project is divided into 2 shapes.。In addition to the regular drain，Also includes an overall width of up to 1270 mm, One side edge height up to 900 mm Special-shaped road drainage ditch。The size of the structure is large，And winding with the mountain roads.，Large camber and slope are common.。
Therefore, the equipment operation skills of the construction team，Professional competence and experience are required.，In the process of erecting the datum line as a guide, the spacing of piles needs to be densified.，Measure the elevation and direction of the datum line.，To make sure SP 15 for superior performance，Flexible control of elevation with reference to the baseline、Direction and inclination，Laid to conform to the height、Large drainage structures with design criteria such as alignment and slope。
The specialist conTractor undertaking this slipform paving project，Yunnan Huanming Construction Engineering Co., Ltd.，It's a highway collection.、Water Conservancy、Municipal、It is a comprehensive construction enterprise with multiple construction qualifications such as housing construction.，10 in the field of road construction Years of construction experience。Buy the first Wittgen in 2017 SP 15 Cement concrete slipform paver。
With the help of Wittgen's technicians,，The company has successfully completed 46 kilometers of ditches in Dachaoshan section, Jingdong County, Puer City, Yunnan Province.、Placing of curbs，Due to Wittgen SP The high efficiency of 15 snatches precious time for the subsequent pavement construction.，Users recognize it very much，Since then, a number of Wittgen slipform pavers have been added.。
In the field of slip-form paving construction，Its construction team has accumulated rich experience in various working conditions.，A total of more than 140 kilometers of anti-collision walls have been poured.，More than 1800 kilometers of ditches were poured.、Construction tasks such as pouring more than 700 kilometers of various small structural parts。
Construction team. Yeah SP I have a deep understanding of the outstanding performance brought by the excellent fuselage structure design.。Front crawler of two parallelogram mechanism swing arms and rear crawler capable of hydraulically extending，The positions of the front and rear tracks can be flexibly adjusted according to the requirements of the project and working conditions.，Side-laid moulds can be installed on either side of the machine。In the case of large-sized structures or graded roads，SP 15 The front two tracks can be opened at a large angle to both sides.，Move the rear track to one side of the mold，In this way, good stability and large driving force can be maintained even when working under heavy load.。
In addition，SP 15 Have several individually adjustable hydraulic vibrators，The exciting force is large，And that vibrate effect is good，Concrete with large section can be vibrated and compacted.、One-time molding，Ensure ideal compactness of concrete material。It is thanks to these machine features.，SP 15 It can meet the laying requirements of various working conditions, different shapes and large-size cement structures with complex road terrain in Yunnan.。
And this time in the construction site trial 3D The construction team was also impressed by the control system's automatic navigation slip-form paving technology.。The prism control elevation installed on the slip-form paver is measured and controlled by the automatic total station on site.，Directional control by satellite navigation system，3D The navigation system is connected to the machine control system，The slip-form paver automatically moves forward along a preset path。
When paving，The machine compares the actual position with the set position，Precise control of elevation、Direction and inclination，The paved cement structure is completely consistent with the design.。
At the application site，The person in charge of the construction party is witnessing 3D After the application effect of digital control technology，Evaluated：“
Wittgen SP 15 using 3D Digital assistive technology，Through the improvement of control accuracy，Not only can the quality standard of the structural parts paved by the slip form be higher,，There is no need to erect a reference line.，It can also save labor and time to a certain extent.，In the long run, it can further reduce costs.。
”Wirtgen Group has always been at the forefront of the industry in digital and intelligent technology.，Committed to providing customers with more efficient solutions through technological innovation。
Not only in the milling and paving sector Wirtgen Group 3D Digital auxiliary construction system is ready，In the field of slipform paving，Wirtgen's various models of slipform pavers are also in place，Equipped with 3D External interface of control system，Can be easily compared with the mainstream 3 on the market.D Digital system connection。
