Abstract

The invention discloses a reinforced concrete beam structure and a construction method for treating a small karst cave foundation, and the construction method is characterized in that a first reinforced concrete beam support and a second reinforced concrete beam support are arranged on a stable foundation on one side of a karst cave, and a first reinforced concrete beam support and a second reinforced concrete beam support are also arranged on a stable foundation on the other side of the karst cave; the first reinforced concrete beam support and the second reinforced concrete beam are arranged on the two sides of the line direction respectively, the first reinforced concrete beam support is used for supporting the first reinforced concrete beam support, and the second reinforced concrete beam support is used for supporting the second reinforced concrete beam. The structure is reliable, and the defect of large post-construction settlement caused by backfilling of small karst caves is overcome.

Description

technical field [0001] The invention relates to the technical field of highway engineering construction, in particular to a reinforced concrete beam structure and a construction method for processing a small karst cave foundation. Background technique [0002] At present, the geology of the southwestern region is complex, and it is impossible to completely avoid the karst area in the selection of the line. Due to the control of design cost and accuracy, even if the reconnaissance drilling holes are drilled at certain intervals according to the specification, it is impossible to detect all the karst caves that the line passes through. After the construction reveals the karst cave, the karst cave will be dealt with. [0003] The most important thing in the treatment of karst caves is to ensure the safety of the structure during construction and operation. At present, the method of backfilling the karst cave is used to treat the karst cave foundation of the construction section...
