Problems solved by technology
[0004] The above flip-type slab gate is taken as an example. At present, the method of replacing the water seals on both sides of the gate in the related art is: first remove the connecting device between the gate and the hoist, and then lift the gate to the ground by hoisting equipment. First, replace the water seals on both sides of the gate; after the replacement of the water seals is completed, lift the gate into the gate groove for installation. The entire replacement is very troublesome and the replacement cost is high

Embodiment Construction
[0043] The existing upward-turning flat gate generally controls the rotation of the gate through a hydraulic hoist to achieve the purpose of changing the degree of opening and closing of the gate. When the hydraulic hoist controls the opening and closing of the gate to a certain position, the position of the valve is fixed by the gate locker to realize the locking of the valve position.
[0044] The following is attached figure 1 The application is described in further detail.
[0045] The embodiment of the present application discloses a method for replacing a water seal on a side of a flat gate. refer to figure 1 , the method of replacing the water seal on the side of the slab gate includes the following steps:
[0046] S1, adjust the opening and closing degree of the gate, open the gate to 90 degrees to the side wall of the gate slot, and fix the gate through the gate locker. At this time, the gate is in a horizontal state, and the gate panel can be used as a working pla...

The invention relates to a method for replacing a bulkhead gate side water seal, and relates to the field of hydraulic engineering maintenance. The method comprises the following steps of: S1, opening the gate to form a certain angle with a gate groove, and fixing the position of the gate; S2, standing on an operation platform; S3, removing an original water seal; S4, preparing a new water seal for installation; and S5, applying force to one side of the gate to push the gate towards the other side of the gate, so that a certain installation gap is formed between one side of the water seal to be installed and the side wall of the gate groove, and installing the new water seal. The method has the effects that the complexity of replacing the water seal can be reduced, and the replacement cost is reduced.
Description
technical field [0001] The application relates to the field of hydraulic engineering maintenance, in particular to a method for replacing a water seal on the side of a flat gate. Background technique [0002] Gates are mechanical equipment in water conservancy and hydropower engineering facilities. It is mainly used in agricultural irrigation, fishery, ship locks, seawater tidal protection, urban river landscape engineering and small hydropower stations to intercept water flow, control water level, adjust flow, discharge sediment and floating objects, etc. [0003] In order to ensure the reliability of the gate, there are water seals on both sides of the gate to increase the sealing performance on both sides of the gate. When the water seal is used for a period of time, due to compression deformation, corrosion and other reasons, it will affect the The normal sealing work of the water seal to the gate, because in order to ensure the effectiveness of the gate seal, the water...
