Pier head type tunnel anchor and construction method
The invention relates to a pier head type tunnel anchor and a construction method and belongs to the technical field of bridge engineering. The pier head type tunnel anchor comprises a front anchor chamber, a rear anchor chamber and an anchor plug body; a main cable is erected in the front anchor chamber; the main cable is scattered into a plurality of main cable steel strands through a cable scattering saddle; the anchor plug body comprises an anchor plug body front end and an anchor plug body rear end which are connected with each other; the anchor plug body front end is located at the rearportion of the front anchor chamber; the sizes of all the cross sections of the anchor plug body front end are consistent; the anchor plug body rear end is located at the front portion of the rear anchor chamber; the sizes of all the cross sections of the anchor plug body rear end are consistent and larger than the size of the cross sections of the anchor plug body front end. Therefore, the anchorplug body formed by the anchor plug body front end and the anchor plug body rear end forms a pier head type anchor plug body; the whole tunnel anchor forms the pier head type tunnel anchor. The pierhead type tunnel anchor has the advantages of small construction difficulty and risk, small overall engineering scale, relatively low manufacturing cost, remarkably improved structural safety, stability and durability.
本申请涉及一种墩头式隧道锚及施工方法，属于桥梁工程技术领域。本申请提供的墩头式隧道锚包括前锚室、后锚室和锚塞体，其中，前锚室内架设有主缆，主缆通过散索鞍分散成多根主缆钢绞线；锚塞体包括相连的锚塞体前端和锚塞体后端，锚塞体前端位于所述前锚室的后部，且锚塞体前端的各个横截面尺寸一致，锚塞体后端位于所述后锚室的前部，锚塞体后端的各个横截面尺寸一致且大于所述锚塞体前端的横截面尺寸。由此，锚塞体前端和锚塞体后端构成的锚塞体形成墩头式锚塞体，整个隧道锚形成墩头式隧道锚。本申请提供的墩头式隧道锚具有施工难度及风险较小、整体工程规模减小、造价相对降低的优势，且结构的安全性、稳定性和耐久性都有显著提高。
