Water-proof structure for civil engineering expansion joint

Abstract

The invention provides a water-proof structure for a civil engineering expansion joint. A sealing plate embedded between two sections of bridges is used, and force accumulation torsional springs are subjected to self force accumulation for a passing vehicle through the force accumulation torsional springs so as to accumulate force for pushing the sealing plate is accumulated. During heavy rain, rain water flows into a water discharging plate in the expansion joint to enter a water receiving bucket. Through a clamping device, the internal force of the force accumulation torsional springs is released to push the sealing plate to seal the expansion joint between two sections of bridges, the rain water can not enter the lower end of the bridge through the expansion joint, and a pier on the lower end of the bridge can not be corroded. The water-proof structure disclosed by the invention is artful, can be produced on batch, performs a water-proof function on the expansion joint in the bridge, and protects the pier on the lower end of the bridge.

Description

technical field [0001] The invention relates to civil engineering devices, in particular to a waterproof structure for civil engineering expansion joints. Background technique [0002] Expansion joint refers to a structural joint vertically set along the appropriate part of the building length to prevent the structure from cracking or being damaged due to climate temperature changes (thermal expansion, cold contraction). The expansion joint is to divide the building components above the foundation such as walls, floors, roofs (except wooden roofs) into two independent parts, so that the building can be horizontally expanded along the long direction. [0003] Many kinds of bridge expansion joints are used in bridge construction in our country, and most of them leak water. Therefore, in the bridges built before, the girder ends and cap beams under the expansion joints are most seriously damaged by water. Since it is difficult to ensure that the expansion joint is completely ...

Problems solved by technology

[0005] In order to solve the defects of the prior art, the present invention provides a waterproof structure for expansion joints in civil engineering, which effectively solves the problems in the prior art that the expansion joints leak water, the water flow corrodes the bridge deck, and causes damage to the bridge deck. If the joints are in normal state, the deformation between the bridges will make the expansion joints bigger and smaller. When it rains, water may leak from the expansion joints and cause damage to the bridge deck. This civil engineering expansion joint waterproof structure will affect the expansion joints. The joints are closed to prevent water from flowing from the expansion joints to the underside of the pier, which protects the pier and ultimately does not affect the deformation between the bridges
