Description

Compared with the traditional linear pretensioning prestressing structure, the broken line pretensioning prestressing structure is designed to enable the distribution of enveloping patterns under the action of prestressing lines and external load bending moment to be close by adopting broken line beam matching, so that the span of a beam body is improved, and meanwhile, the shearing capacity of a web plate can be improved by bending steel beams, the cracking of the web plate is avoided, and the durability of the beam body is improved. Compared with the traditional post-tensioning method prestressed structure, the quality problem caused by non-compaction of grouting is avoided, the durability of the structure is improved, and the later maintenance cost is reduced. The corrugated pipe and special anchor devices are not needed during manufacturing, construction procedures are reduced, and the manufacturing scale reaches a certain amount, so that the corrugated pipe has the advantage of obvious manufacturing cost.

When the existing Bulb-T beam is in tension construction, a larger counter force (taking a 40 m standard span as an example, the tension force is controlled to be 1200T) needs to be provided by a counter force end, and the requirements on the strength, the rigidity, the foundation stability and the anti-pulling bearing capacity and the shearing bearing capacity of the pile foundation of the counter force wall are extremely high. The steel structure counterforce wall has high self strength, but needs a steel box stay bar as a support, and has large steel consumption and high manufacturing cost; in order to obtain enough bearing capacity, the reinforced concrete counterforce wall needs a large amount of auxiliary stress of the earwall, and the counterforce wall needs more reinforcing steel bars, so that the consumption of concrete is large, and fatigue cracking phenomenon is easy to occur under the action of long-term cyclic load. The pile foundation is used as a main source of pulling resistance, and needs enough anchoring depth and larger pile diameter. The rock foundation is not suitable for adopting PHC pipe piles, only reinforced concrete piles can be adopted, the pile foundation reinforcement rate is high, a large-scale drilling machine is required for construction, the construction period is long, and the overall economy is poor.
