Reinforcing structure for soil body above existing tunnel and construction method of reinforcing structure
The invention relates to a reinforcing structure for a soil body above an existing tunnel and a construction method of the reinforcing structure, and belongs to the technical field of soil body reinforcing construction. The reinforcing structure comprises a soil body reinforcing area, the soil body reinforcing area comprises a strong reinforcing cross beam soil body area and weak reinforcing soil body areas, the strong reinforcing soil body area comprises a cross beam section and two supporting leg sections arranged on the lower portion of the cross beam section, the two supporting leg sections are erected on the two sides of the existing tunnel in the construction line direction of a newly-built tunnel respectively, the number of the weak reinforcing soil body areas is two, the two weak reinforcing soil body areas are oppositely arranged in the construction direction of the newly-built tunnel, the cross beam section is arranged between the two weak reinforcing soil body areas, the weak reinforcing soil body areas and the cross beam section are combined to form a cross beam area, and the newly-built tunnel penetrates through the cross beam area. According to the reinforcing structure for the soil body above the existing tunnel and the construction method of the reinforcing structure, the influence on the existing tunnel can be reduced in the overpass construction process of the newly-built tunnel, and the construction safety and the normal operation of the existing tunnel are ensured.
一种既有隧道上方土体的加固结构及其施工方法，属于土体加固施工技术领域。它包括土体加固区，所述土体加固区包括强加固横梁土体区及弱加固土体区，所述强加固土体区包括横梁段及设置在横梁段下部的两个支腿段，两个支腿段沿着新建隧道施工线路方向，分别直立在既有隧道的两侧，所述弱加固土体区的数量为两个，两个弱加固土体区沿着新建隧道施工方向相对排列设置，所述横梁段设置在两个弱加固土体区之间，所述弱加固土体区及横梁段组合形成横梁区，所述新建隧道穿过横梁区。本发明能够在新建隧道上跨施工过程中，减少对既有隧道的影响，确保施工的安全性及既有隧道的正常运行。
