Example Embodiment

[0029] The technical solutions of the present invention will be further described below with reference to the accompanying drawings.

[0030] Refer figure 1 and figure 2 The waterproof structure of the embodiment of the present invention is used to connect the corner portion of the box type tube intent, and the corner of the box type is connected by a corrugated plate flange 100 and the bolt 300. The plate flange 100 between the top plate is connected between the top plate, and the plate flange 100 and the top plate having an acute angle between the plate flange 100 and the top plate. The plate flange 100 on the upper end of the side panel is integrated with the side plate, and the plate flange 100 in the bottom of the side plate is welded with the side plate. The plate flange 100 at both ends of the bottom plate is integrally formed with the bottom plate.

Abstract

The invention discloses an underground pipe gallery waterproof structure and a construction method. The underground pipe gallery waterproof structure comprises a waterproof gasket, a bolt, a waterproof filling layer and a waterproof film; the waterproof gasket is arranged between two plate-type flanges at the corner connecting position, the bolt penetrates through the two plate-type flanges at the corner connecting position and the waterproof gasket, the head portion of the bolt is opposite to a box-type pipe culvert, a nut faces the box-type pipe culvert, the acute angle space formed between the plate-type flanges of the box-type pipe culvert and a corresponding top plate or side plate is filled with the waterproof filling layer, and the nut of the bolt is immersed in the waterproof filling layer; the two ends of the waterproof film are connected to the junction of the waterproof filling layer and the corresponding top plate or the side plate and the outer surfaces of the plate-type flanges at the bolt head of the corresponding bolt correspondingly, the bolt head of the bolt is covered, and the waterproof film is tightly attached to the corresponding waterproof filling layer and the outer surfaces of the two plate-type flanges. According to the underground pipe gallery waterproof structure of the technical scheme, the waterproof filling layer and the waterproof film can form an external waterproof layer, and the waterproof performance of the pipe culvert is further improved.

Description

technical field [0001] The invention relates to the field of box-shaped culverts, in particular to a waterproof structure and construction method of an underground pipe gallery. Background technique [0002] The corrugated steel plates of box-type pipe culverts are usually connected by plate flanges, and rubber pads or gaskets for waterproofing are provided between the plate flanges. However, when the pipe gallery is deeply buried and the groundwater level is high, there will still be leakage and seepage. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to propose a waterproof structure for underground pipe gallery, which can further reduce the leakage and seepage of pipe culverts. [0004] Another object of the present invention is to propose a construction method of the above waterproof structure, which can timely find the leakage and seepage during the construction process, and improve the airtightness of the pipe culvert. ...
