| description | The invention relates to an anti-bubble concrete formwork. One end of a blind pipe is blocked, the other end of the blind pipe is open, a nail mounting seat is coaxially arranged on the outer wall of the open end of the blind pipe, the nail mounting seat is of an annular structure, at least two nail positioning holes are symmetrically formed in the nail mounting seat, positioning nails are inserted in the nail positioning holes, at least one side face exhaust hole is formed in the outer wall of the blind pipe, the outer wall of the blind pipe is further sleeved with an outer sleeve, the outer sleeve can block the side face exhaust hole, and meanwhile the outer sleeve is moved so that the side face exhaust hole can be opened and communicated with the outside. The invention further discloses a method for improving the quality of steam turbine air duct wallboard concrete. The anti-bubble concrete formwork has the following beneficial effects that a concrete pouring construction process is designed and optimized |
