Analysis of the Causes of Water Leakage in the Gate

1. Analysis of the cause of water leakage of hydraulic flat steel gate

Analysis of Water Leakage Causes of Hydraulic Plane Steel Gate

① The conflict and wear of the water-stop embedded parts cause water leakage. The water-stop embedded parts are severely corroded in an underwater humid environment, and the opening and closing process of the gate creates a loose touch between the water-stopping parts of the gate and the water-stopping embedded parts, resulting in water leakage;

②The installation of the door is not correct, and the skewed displacement occurs after the gate is closed. The installation of the water stop did not meet the planning requirements and operating specifications. The water stop pre-tightening amount was too large, causing the head to turn or deform, resulting in water stop damage; the pre-tightening amount was too small, and water leakage occurred under the action of high head pressure.

2. Causes of water leakage at the curved steel gate

①The water stop of the curved door is not on the same plane or curved surface, and the water stop has turns, overlaps, and overlaps to form water leakage.

② Planning defects, there is no ventilation hole planned between the curved working door and the overhaul gate, which causes water stop damage.

③The manufacturing precision of the curved door panel did not meet the planned straightness requirements, causing water leakage due to uneven touch and tightening of the top fixed water stop and the gate panel.

④The debris is jammed. The long-term immersion of the door body, door groove and track of the steel gate in the water leads to the attachment of aquatic organisms. When the gate is leaking, the gravel, stones, and waste drifting services in the water are stuck between the waterstop, the track, and the door slot, causing water leakage.

⑤In the daily maintenance and reinforcement, the parapet wall and gate pier are sprayed with carbonized spray, and the residues in the door groove and track are not cleaned up; the door groove concrete is carbonized and segregated and other reasons cause water leakage.

3. Reasons for water leakage of reinforced concrete gate

3.1 Engineering construction

①The reinforced concrete gate uses a plate-beam structure to reduce the weight of the door body. The thickness of the panel and the width of the beam are small, and the content of steel bars is large and dense. The vibratory compactness of the formed concrete is affected. The second is that the water entering the gate causes the steel bars to corrode and swell, leading to cracks in the tendons.

②The prefabrication of the gate makes the size not up to the standard and the rectangular shape is irregular. When the door is closed, the two ends are not aligned to form a tight water stop and leak.

③The bolt diameter is smaller than the hole of the water stop rubber, and the pressure water leaks from the gap of the hole.

④ The prefabricated assembly of the gate is misaligned, and the water leakage between the plates is improperly selected. The sealing of the water-stop rubber is not tight, and the joint between the water-stop rubber and the gate pier is not sufficiently cleaned and smoothed to cause water leakage when pouring. 3.2 Operation management

① The rollers of the gate are in a high humidity environment, and the rust is serious, causing serious sliding conflicts. The uneven force on the gate during operation causes the door body to twist and leak.

②The position of the wire rope of the hoist is not in place, and the lifting point changes, which causes the movement of the water stop rubber to affect the water stop effect, or the water leakage occurs in the door groove
