The invention discloses a UHPC cross beam unit for a bridge tower, the UHPC cross beam unit is of a hollow box type structure, the hollow box type structure comprises a UHPC top plate, a UHPC bottom plate and UHPC webs, the two sides of the UHPC top plate are connected with the two sides of the UHPC bottom plate through the UHPC webs, and UHPC stiffening ribs are arranged in the hollow box type structure. The invention further provides a UHPC cross beam for the bridge tower. The UHPC cross beam is mainly formed by splicing a plurality of UHPC cross beam units. The invention further provides the bridge tower and a construction method thereof. According to the UHPC cross beam, the construction difficulty can be reduced, it can be guaranteed that the structure has good crack resistance, the cracking risk of the bridge tower cross beam is effectively reduced, and safe and durable operation of the bridge tower cross beam of a large-span bridge is guaranteed. 本发明公开了一种用于桥塔的UHPC横梁单元，所述UHPC横梁单元为中空箱型结构，所述中空箱型结构包括UHPC顶板
