Guided by the actual problems in the construction of foundation and foundation engineering, after a lot of foundation research work, in-depth analysis and research, the construction method of quick loading and quick unloading recyclable anchor cable was effectively solved The existing construction technology is complicated, the labor intensity is high, the recovery equipment is complex and bulky, the recovery rate is low, and the cost is high.
Evaluation of case: Sichuan Zhide Geotechnical Engineering Co., Ltd.
The achievement has been successfully applied to three projects such as Wujiaba in Kunming.
organized 7 experts in the same industry to evaluate the construction method of quick loading and quick unloading recyclable anchor cable The “construction method of quick loading and quick unloading recyclable anchor cable” independently completed by Sichuan Zhide Geotechnical Engineering Co., Ltd.
The system includes theoretical methods, classified evaluation indicators, big data analysis framework, service specifications and so on.
It solves the recycling problem of prestressed anchor cable for foundation pit slope support, expands the application range of prestressed anchor cable, saves the support cost, does not occupy underground space for a long time, reduces the impact on the surrounding environment, and improves and perfects the traditional anchor cable technology.
has implemented the evaluation of scientific and technological achievements.
3.
The main innovations are as follows: 1 The achievement adopts the construction of fast loading and unloading recyclable prestressed anchor cable, which has high reliability and stability in combination installation, handling and demolition, and is convenient to use.
The actual effect is good, the cost of foundation pit support is saved by about 30%, the economic and social benefits are remarkable, and the application prospect is broad.
technical level: domestic leading level comprehensive score: 88.1 points review experts: Li Yaojia (MCC Chengdu survey and Research Institute Co., Ltd.), Liu Xiaodong (Sichuan Chuanjian survey and Design Institute Co., Ltd.) and Zhou Ling (Sichuan Geological Engineering Survey Institute Group Co., Ltd.), Dong Jianhui (Chengdu University), Zhang Liang (Southwest Jiaotong University), Fu Chenghua (Xihua University), Feng Xuemin (China Power Construction Group Chengdu survey, design and Research Institute Co., Ltd.) in this achievement, the unit carried out the research on the construction method of quick loading and quick unloading recyclable anchor cable.
The construction method of this achievement is simple, the construction quality is easy to control, and the recovery mechanism is sensitive, fast and labor-saving.
