Abstract

The invention discloses a tube corridor connector sealing device. The tube corridor connector sealing device structurally comprises a waterproof sealing belt which is arranged below the earth surface, and the middle portion of the waterproof sealing belt is arranged to in a V shape; the two V-shaped ends of the waterproof sealing belt are provided with an upper groove and a lower boss, and an elastic depression bar fixed into the groove through buckling modules is arranged in the groove; embedded structural steel is arranged in cement components at tube corridor connector plane parts on the two sides of the waterproof sealing belt, rotary buckles used in cooperation with the embedded structural steel are arranged in grooves of the embedded structural steel, the upper portions of the rotary buckles are inlaid into the buckling modules, the tops of the two buckling modules are provided with joint cover plates aligned with the earth surface, and the joint cover plates are fixed in the manner that the two ends of the joint cover plates penetrate into the buckling modules and two bolts of the rotary buckles. The tube corridor connector sealing device has the beneficial effects that the good waterproof effect is achieved, horizontal and vertical turning and side elevation and inclination face installation can be achieved, the installation period is short, and maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of comprehensive pipe gallery, and more specifically, the invention relates to a pipe gallery interface sealing device used for underground comprehensive pipe gallery. Background technique [0002] The underground comprehensive pipe gallery is a public infrastructure formed by placing two or more pipelines in it. It is one of the modern and scientific standards for urban development. One of the key technologies for long-term stable operation. [0003] The traditional waterproof structure is to place waterproof materials at the joints of the comprehensive pipe gallery. However, due to the impact of the groundwater level, soil quality, and changes in the side load of the upper layer, the comprehensive pipe gallery is often prone to various deformations such as torsion and warping at its joints. The joints are cracked, which leads to the failure of the waterproofing of the comprehensive pipe gallery. Conten...
