Application of Pressure-Dispersed Anchor and Steel Tube Pile in Slope Protection 压力分散型锚索和钢管桩在边坡支护中的应用
This paper introduces the case histories of the application of artificial hole forming anchor ( method of Luoyang shovel hole forming, method of high pressure anchor tube) in the foundation pit pro- 本文介绍了人工成孔(洛阳铲成孔法、高压锚管法)锚杆在基坑工程中的应用实例。
The analysis and test results show that the concentration of stresses at the end of fillet welds between the tensile anchor plate and the tensile anchor tube is obvious, and the maximum principal tensile stress occurs in the stress concentration region. 结果表明,锚拉板与锚拉筒之间的连接焊缝下端部应力集中明显,最大主拉应力出现在该区域;
The application of pressure-dispersed anchor wire, steel tube pile and frame girder in slope protection takes a good effect and gives a feasible way of protecting weak slope in our country. 压力分散型锚索,钢管桩和框架梁的联合支护,在边坡治理中取得了良好的支护效果,为我国在软弱边坡支护方面提供了一种可行的方法。
This anchor has been used in 142 oil wells, and it shows that it can both release oil to decrease the pollution of crude oil and produced water and fix the tube to increase the pump efficiency and reduce the check period of pump. 经过142井次的使用,证明该二合一液压锚定器既能泄油,减少原油、污水污染,又能锚定管柱,提高泵效,减少检泵周期。
Under five meter depth, the vertical anchor tube of infuse slurry was increased to prevent the deep slippage. 对于深五米以上地段增加了竖向注浆锚管以防止深部滑移;
Using self-boring grouted rock external screw bolt to build geotechnical anchor, is the key technique by which resolve the difficulty of the construction in complex geologic circumstances. And external screw steel tube rolling is the key equipment to manufacture finish rolling external screw steel tube. 使用自钻注浆式外螺纹锚杆进行岩土锚固施工,是解决复杂地质条件施工难题的关键技术,而外螺纹钢管轧机则是生产精轧外螺纹钢管的关键设备。
The concrete wet spraying machine, which is widely applied in Spray anchor bracing engineering field, is a type of special equipment, while S tube valve is one key component of the concrete pump. 混凝土湿喷机是一种广泛应用于地下工程喷锚支护的专用设备,而S管阀是其混凝土泵中一个至关重要的部件。
The nature and stability of Soil Similar Slope are analyzed, the adaptability plus with advantages of prestressed anchor cable frame and prestressed anchor cable frame combined with steel floral tube are discussed. 本文对类土质边坡的稳定特性进行了分析,对预应力锚索框架和预应力锚索框架+钢花管复合支护方式在类土质边坡加固应用进行了探讨。
