Reinforced concrete beams (width B500 and height H600 are changed according to the water level) are added on the top plate according to the scheme, and the method is used for reinforcing the hole 14 and preventing water level rising (Yangtze river tide) in the construction process.
Step 3, manufacturing a gate;
the construction scheme without stopping water is to adopt two types of gates, namely a gravity reinforced concrete gate (shown in figures 3 and 4) and a construction steel gate (shown in figure 5).
The gravity gate is mainly suitable for the working condition without water cut-off, and the principle is as follows: under the working condition that the new and old drainage ditches are communicated, the water flow is changed by utilizing the resistance of the gravity gate, and the underwater concrete is required to be poured for the second time after the actual installation, so that the old box culvert is plugged. Practice proves that the use effect is good.
The working principle of the construction steel gate is as follows: a small hole is formed in the wall of a box culvert in the coverage area of a steel gate (containing rubber water stop) which is initially installed in place, water is discharged (water pump is matched for drainage), so that negative pressure is formed between the steel gate and the wall instantly, and the steel gate is attached to a reinforced concrete wall by utilizing water pressure. The concrete wall and other works can be removed by staff according to the design requirement in the coverage area of the steel gate outside the original wall.
And 4, after finishing project inspection and acceptance (closing all the overhaul gates before the cofferdam is disassembled by the water outlet) of a new circulating water ditch (box culvert), a water outlet and the like and working of modifying an old box culvert and manufacturing the gates, performing preparation work before switching without stopping water by tissue inspection, and performing the switching operation without stopping water of circulating water after preparation is complete.
