Flashing and usage thereof and method for preventing water seep in cement concrete pavement and bridge surface slab joint

Abstract

The invention relates to a waterproof structure used to avoid the water at the surface of joints of cement concrete road and bridge plate to leak into road and bridge, and a method for using waterproof sheet to avoid the surface water at the joints leaked into inner structure, belonging to road project technique. The invention irrigates, adheres or mounts sheet structure on the joints of cement concrete road and bridge, irrigates, adheres or mounts waterproof sheet structure when irrigates or mounts road and bridge plates, while the sheet structure can be plane, or fold shape, with aging resistance and corrosion resistance corresponding to the road and bridge plates. The invention can adapt with deformation and movement of road and bridge plates, to seal and avoid water leaked into road and bridge, with simple structure, easy construction, improved waterproof effect, prolonged service life of road and bridge and improved application property, improved normal traffic time, reduced maintenance and construction costs of road and bridge.

Description

technical field [0001] The invention relates to a waterproof sheet and its use, as well as a method for using a sheet-like structure to prevent leakage of water from the joints of cement concrete pavement and bridge deck blocks into the internal structure of the pavement and bridge deck, belonging to the technical field of road and bridge engineering. technical background [0002] In the existing cement concrete pavement and bridge deck, in order to prevent the cement concrete slab from generating stress under the action of temperature, climate, etc., resulting in expansion, deformation or torsional deformation, it is necessary to set expansion joints; sew. Due to the existence of expansion joints or construction joints in cement concrete pavement and bridge deck blocks, when rainwater exists or flows on the pavement and bridge deck, the rainwater will leak from the joints of the pavement and bridge deck blocks to the pavement and bridge deck structure. , resulting in the a...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the defects of the above-mentioned existing road surface and bridge deck joint anti-seepage water materials and structures, and invent a kind of sheet structure to prevent cement concrete road surface and bridge deck surface water from leaking into the road surface and bridge surface from the seam. The method and structure inside the surface structure to solve the waterproof problem of the road surface and bridge deck, improve the strength of the road surface and bridge deck structure, reduce the impact of water on the road surface and bridge deck structure, prolong the service life of the road surface and bridge deck and improve the road surface , The performance of the bridge deck, prolong the normal traffic time of the road surface and bridge deck, reduce the maintenance time and cost of the road surface and bridge deck
