Study On Earth Mooring Rod Test And Construction Technique Adopted In The HaiHe Bank Reinforcing Engineering In Tianjin

Integrated alteration engineering of Haihe lie in the top place of fivedevelopment stratagems in Tianjin, and bank reinforcing engineering is a crucialcomponent of this project. Considering the geography location, surroundings andrevetment structures of the Haihe riversides in the city, a difficult problem isencountered in implementing earth mooring rod technique. Earth mooring rod isapplied to soft soil stratum as a perpetuity engineering measure, however, theengineering effect need to be proved by experimental results.The design scheme of continuous concrete wall with earth mooring rod is appliedto bank modification structural style on the right bank of Taierzhuang roadsector(Liuzhuang Float Bridge-Guanghua Bridge) in Haihe river. The elementaryprinciples and characteristics of anchoring engineering in rock and soil arerepresented. The classification and structure of mooring rod are discussed in details,aswell as the specific construction procedure of anchoring engineering.The purpose, conditions and process of this mooring rod basic test is discussed inthis thesis。Based on the observation dates,several problems such as limit bearingforce, displacement, force endured by the moored section of mooring rod andpresstress loss of earth mooring rod are analyzed.The designing parameters of the anchoring construction of Haihe bankreinforcing engtineering, the equipments, technology and measures adopted toguarantee construction quality are described. The society and economy benefitsgained by implementing mooring rod technique to Haihe bank reinforcing engineeringare discussed in this paper, and some problems are proposed concerning thisconstruction technology.
