According to later information, I know that the construction thoughts is: First, construct a removable bridge made of reinforced concrete, then move it entirely under the railway. 根据后来的了解,得知桥的建设思路是,首先在铁路东侧构建一个钢筋混凝土桥体,然后采用整体推移的方法,将其挪到铁路底下。
Conclusion: Removable partial denture is the main method of the prosthetic treatment in the elderly patients with diabetes Mellitus Oral hygiene is very important to the patient when fixed bridge was used. 结论:老年糖尿病患者义齿修复以活动义齿为主,固定义齿修复时应注意口腔卫生情况。
Development and application of a new removable bridge plug 一种新型可取式桥塞的研制与应用
In accordance with the need of bottom water shutoff for many oil and water wells in oilfield, a new type removable bridge plug was designed. 根据油田油水井堵底水的需要,设计了一种新型可取式桥塞。
External prestressed concrete technology full display through removable and re-stressed, will impel the bridge structure the big development, to will study the new bridge structure, the great span bridge structure has the enormous direction function. 体外预应力技术充分发挥体外预应力可更换和二次张拉调索的突出优点,将推动桥梁结构的大发展,对研究新型桥梁结构、大跨度桥梁结构具有极大的指引作用。
