【摘要】：一些新建码头投入使用后,在运营期间,缺少维护,有些码头的使用甚至超过了设计规定的使用年限,码头桩身出现破损的情况,一些部件受损严重,在安全使用方面,无法得到有效的承载保证。在码头运营期间,货轮在装载和卸载集装箱货物的过程中,码头自身的构件在各种复杂的荷载作用下,会因为超出正常承载力范围、长期的疲劳、偶然的碰撞等造成码头桩身整体或是局部的破坏,从而影响到码头建筑物结构的耐久性和承载能力。桩基长期处于海水浸泡恶劣环境中,会钢筋混凝土构件产生锈蚀开裂。本文依托浙江某集装箱码头桩基修复工程项目的的施工实例,通过收集相关数据和资料、现场实践、校外导师的指导等,来分析研究高桩码头耐久性修复工程中的钢套筒灌浆修补的关键技术。首先根据工程资料,码头结构采用高桩梁板式结构,明确裂缝出现在整个码头的位置以及裂缝深浅和大小。其次,根据修补工程特点和设计要求,选择确定钢套筒的灌浆修补方案。以此为依据,编制具体的修补施工方案和具体施工组织部署。最后,制定该高桩码头修补工程在施工过程中的各项保证安全生产的措施。在保证工期的情况下,不影响码头的正常使用。本文的研究成果对类似高桩码头的灌浆修补工程的施工,具有重要的实践价值和广泛的推广意义。
[Abstract]:After some newly built wharves are put into operation, they lack maintenance during operation, and some of them even exceed the service life prescribed by the design. The pile body of the wharf is damaged, and some parts are seriously damaged, so they can be used safely. During the operation of the wharf, during the loading and unloading of container cargo, the components of the wharf itself under various complicated loads will be subjected to long-term fatigue due to exceeding the normal bearing capacity. Accidental collision causes the whole or local damage of the pile body of the wharf, which affects the durability and bearing capacity of the structure of the wharf building. The pile foundation is in the harsh environment of seawater immersion for a long time. The reinforced concrete members will be corroded and cracked. This paper relies on the construction example of the pile foundation restoration project of a container terminal in Zhejiang Province, through collecting relevant data and data, field practice, guidance from outside school tutor, etc. To analyze and study the key technology of steel sleeve grouting repair in durability repair of high pile wharf. Firstly, according to the engineering data, the wharf structure adopts high pile, beam, plate structure, It is clear that the crack appears in the position of the whole wharf as well as the depth and size of the crack. Secondly, according to the characteristics of the repair project and the design requirements, the grouting repair scheme of the steel sleeve is selected. To draw up the concrete mending construction plan and the concrete construction organization and arrangement. Finally, the measures to ensure the safety of production in the construction process of the repairing project of the high pile wharf are worked out. Under the condition of ensuring the duration of the project, The research results of this paper have important practical value and extensive popularization significance to the construction of grouting repair works similar to high pile wharf.
