<P>By the Chongqing Jiaotong University, Chongqing Construction Engineering Group Co., Ltd. and other units jointly assume the Ministry of Transport construction technology project "new modular anti-skid retaining structure mechanism" through acceptance. The project developed a combination of anti-slide pile can effectively control the western mountain road landslides.<a href="http://maintenancemachineprice.com//crack-repair/patching-asphalt-manholes-types.html">patching asphalt manholes types</a></P>
<P>According to reports, China's western mountain natural geographical and geological structure is complex, fragile environment, geological disasters, diverse, high frequency of occurrence. The research on the new prevention and control technology of geological disaster, especially the research of high thrust landslide prevention technology can not meet the demand of engineering practice. In this paper,<a href="http://maintenancemachineprice.com//road-maintenance-machinery/used-hydraulic-hammers-for-sale.html">used hydraulic hammers for sale</a> the project is composed of H-shaped, door-shaped composite anti-slide pile as the research object, the combined anti-skid retaining structure of the force mechanism, design calculation method and construction technology and other aspects of a systematic study, Anti-slide pile design calculation method, construction technology and quality control standards, and the preparation of the H-shaped composite anti-slide pile construction technology guide.</P>
<P>The research results of the project have been successfully applied to the landslide prevention and control project of Daozhen Expressway in Nanchuan to Guizhou. The results show that under the same landslide thrust,<a href="http://maintenancemachineprice.com//crack-repair/asphalt-hot-box-trailer-for-sale.html">asphalt hot box trailer for sale</a> the maximum bending moment of the composite anti - slide pile is only one third of the ordinary anti - slide pile. When implementing the same anti-skid effect, the modular anti-slide pile can save about 30% of the project cost.</P>
