The utility model provides an interim mound zhi fanli monitoring devices of bridge construction stage has erect the transverse distribution roof beam between the top of the interim mound of adjacent steel pipe, span centre department on one side of the transverse distribution roof beam lays a set of surface strain meter by the centre to upper and lower both sides, lay a set of displacement meter by span centre department to both ends in the transverse distribution soffit, it is fixed that the displacement meter passes through the displacement meter support, and displacement meter support bothends are fixed respectively on the adjacent interim mound of two steel pipes, displacement meter, surface strain meter passing signal line is connected with strain acquisition instrument, transmits for data process system behind the signal conversion that strain acquisition instrument gathered displacement meter, surface strain meter, and the deflection of data process system through the transverse distribution roof beam gathered calculates the zhi fanli of the interim mound of steel pipe. The utility model discloses carry out girder when construction at the interim dun ding of steel pipe, thegirder load makes the transverse distribution beam deflection be out of shape, but pass test the transverse distribution roof beam bending stress, amount of deflection inverse this locate mound top zhifanli, and low in manufacturing cost is honest and clean, the real -time accuracy of data.
