Construction method for rebuilding building above super shallow-buried tunnel
The invention relates to a construction method for rebuilding a building above a super-shallow-buried tunnel. The construction method includes the following steps that A, after a body structure of the tunnel is constructed, supporting foundations are constructed on bed rock at the two sides outside a tunnel excavation contour line, and the distance between each supporting foundation and the tunnel contour line is over five times larger than the span length of a tunnel hole; B, piers are arranged on the supporting foundations at the two sides; C, a beam body is put up on the piers at the two sides, and a simply supported bridge structure mode is formed by the beam body and the piers at the two sides; D, the building to be rebuilt is rebuilt on the beam body. According to the construction method, the supporting foundations, the piers and the beam body are used for forming a simply supported bridge, the simply supported bridge structure mode is adopted to span a tunnel lining structure, then the building is rebuilt on the simply supported bridge, and therefore it is avoided when a foundation of the rebuilt building is directly located over the tunnel, the safety and durability of the tunnel lining structure are affected negatively.
