The invention discloses a framing discontinuous construction method for a
steel dam gate, which comprises the following steps:
framing construction is adopted, a left part and a right part are divided into a first period and a second period, a
flood season is arranged between the first period and the second period, and
flood season structure construction is carried out after the first period structure construction is completed, so that the safety
flood season of a first-period built structure is protected and preparation is made for second-period
cofferdam precipitation; the construction method comprises the following specific construction steps: S1, determining a left and right construction
boundary line and a construction sequence; s2, first-stage construction; s3,
flood control structure construction; s4, ending the first-stage construction; s5, second-stage construction; wherein the
flood control structure in the step S3 comprises a junction protection part, a water interception curtain, a thickened
cushion layer, a concrete strip, a concrete panel, a blind
ditch and a water collecting well. According to the method, the built structure of the right part can be effectively and fully protected, safe flood fighting can be achieved, the settlement volume of the junction of the left part and the right part is continuously monitored so that structure parameters can be timely adjusted during left part construction, and the problem that water cannot be pumped and drained due to the fact that the left part
cofferdam is partially built on a
gabion section and a
riprap section is solved.
