Embodiment 1

[0025] Example 1: As shown in Figures 1 and 4, the waterproof sheet is a flat rubber sheet that can be stretched and twisted under the action of external force, and its purpose is to prevent the leakage of surface water at the joints of cement concrete pavements and bridge deck blocks The internal structure is used to be buried in the cement concrete slabs on both sides of the joint between the pavement and bridge deck slabs.

[0026]The method of using a waterproof sheet to prevent the surface water from leaking into the internal structure at the joints of cement concrete pavement and bridge deck blocks is to install a flat rubber waterproof sheet at the joints of cement concrete pavement and bridge deck blocks to prevent water leakage on the surface of the road and bridge. into the pavement and bridge deck structures. The setting of the waterproof sheet is to pour the waterproof sheet into the cement concrete slabs on both sides of the joint along the longitudinal direction ...

Embodiment 2

[0028] Example 2: As shown in Figures 2 and 5, the waterproof sheet is a copper sheet with a wrinkled structure in the middle (telescopic torsional bending structure), and its purpose is to prevent the surface water seepage at the joints of cement concrete pavements and bridge deck blocks It leaks into the internal structure and is used to be buried in the cement concrete slabs on both sides of the joint between the pavement and bridge deck slabs.

[0029] The method of using a waterproof sheet to prevent the surface water from leaking into the internal structure at the joints of cement concrete pavement and bridge deck blocks is to set a middle wrinkled structure (telescopic torsion bending structure) at the joints of cement concrete pavement and bridge deck blocks. The sheet copper waterproof sheet prevents the water from the surface of the road and bridge from leaking into the pavement and bridge deck structure. The setting of the waterproof sheet is to pour the waterproof ...

Embodiment 3

[0031] Example 3: As shown in Figures 3 and 6, the waterproof sheet is an aluminum sheet with a wrinkled structure (telescopic, twisted and bent structure) in the middle, and upward hook structures on both sides. The purpose of the waterproof sheet is to prevent the surface water from leaking into the internal structure at the joints of cement concrete pavement and bridge deck blocks, and to be buried in the cement concrete slabs on both sides of the joints between the pavement and bridge deck blocks.

[0032] The method of using a waterproof sheet to prevent the surface water from leaking into the internal structure at the joints of cement concrete pavement and bridge deck blocks is to set a middle wrinkled structure (telescopic torsion bending structure) at the joints of cement concrete pavement and bridge deck blocks. Sheet aluminum waterproof sheet (there are hook-shaped structures on both sides of the waterproof sheet to strengthen the connection and fixation between the w...

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...
