An improved method and structure of arc door bottom water seal

Abstract

The invention discloses an improvement method and structure of a bottom water seal of a radial gate. The method is characterized in that the bottom water seal is arranged on the bottom edge of the downstream side of the gate; the bottom edge of the gate is vertically arranged and is of a triangle structure formed by a panel, a small cross beam and a vertical plate, and thus the rigidity as well as the stability of the gate can be improved; a supporting plate is arranged on the vertical plate; the upper end part of the bottom water seal is limited through the supporting plate, and the bottom water seal is fixed through a water seal pressing plate; the bottom water seal is vertically arranged and can prevent the bottom edge of the gate from being impacted by water flow, and as a result, the shock resistance of the gate can be improved. According to the improvement method, the bottom edge of the gate is vertically arranged; the bottom water seal is in close contact with a bottom sill in the gravity direction, so that the water stopping effect of the gate can be improved; the panel, the small cross beam and the vertical plate form the triangle structure, so that the stability is improved, and the gate rigidity can be improved, and as a result, the bottom edge of the gate can be effectively prevented from being impacted by the water flow, and the shock resistance of the gate can be improved.

Description

technical field [0001] The invention relates to an improved method and structure of an arc gate bottom water seal, belonging to the technical field of water conservancy and hydropower engineering gates. Background technique [0002] The arc gate can be divided into surface hole and submerged hole according to the orifice type. For the surface hole arc gate, the bottom water seal is usually installed on the upstream side, and a support plate is set on the upstream side of the gate panel to limit the upper end of the gate. The water seal pressure plate fixes it, because the bottom of the surface hole arc door is usually an overflow surface, and the bottom water seal and the bottom sill of the gate are a long and narrow interface. Considering that the water seal can be evenly compressed by 5mm to achieve a good water-stop effect, the bottom water seal It needs to be cut according to the actual situation on site, and the bottom water seal is located in the narrow space on the up...

Problems solved by technology

For down-the-hole arc gates, the bottom water seal is usually set on the downstream side, and a support plate is set on the downstream side of the gate panel to limit the upper end and fix it with angle steel. Because the bottom of the down-the-hole arc gate is flat, the bottom water seal It forms an inclined angle with the bottom sill of the gate, and the bottom water seal slightly protrudes from the pressure plate. When the gate discharges water, the bottom water seal will bend upward under the impact of the water flow, which will easily induce vibration and cause the bolts to loosen, especially in the case of high-speed water flow. outstanding, so the existing technology is still not perfect
