Embodiment 1

[0038] Base inspection

[0039] Check whether there is any disease or defect on the concrete base surface, whether there is steel head, whether there is organic matter, paint and other bonding substances, whether there is oil stain, laitance, loose matter, etc.

[0040] Surface treatment

[0041] Remove all kinds of foreign matter, excess matter, organic matter, paint and other adhesives, oil stains, laitance and other unclean substances and loose matter. Repair diseased or defective parts, and deal with steel head parts.

[0042] Clean the roughened concrete base surface with a wire brush, chisel, and high-pressure water gun. Use high-pressure water guns, palm brushes, etc. to clean the treated concrete base surface, without any suspended matter remaining on the surface, to meet the requirements of hair, moisture and cleanliness.

[0043] Gross: The base surface should be rough enough to fully expose the capillary channels of the concrete structure.

[0044] Moisture: The...

Abstract

The invention provides a process for treating durability diseases of a bridge structure on the basis of an XYPEX material. Special construction process treatment is carried out on the durability diseases of the bridge structure by using the XYPEX material to improve density and strength of a concrete structure, resist various diseases and chemical erosion and protect the protecting capacity of a concrete structure beam to a reinforcing steel bar; therefore, the anti-collision capacity of the concrete structure is improved, problems of neutral carbonization and oxidation of concrete or reaction and freeze thawing of alkali aggregate (AAR) are preferably solved and the service life of a reinforced concrete beam is prolonged so that the durability of the bridge structure is enhanced.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a process for treating durability diseases of bridge structures based on XYPEX materials. Background technique [0002] In the existing technology, due to construction defects, the concrete has honeycomb, pockmarked surface, exposed ribs, bridge deck pavement damage, beam cracks, chloride ion erosion, freeze-thaw and other diseases caused by harsh use environment and overload, which will further lead to concrete damage. Durability diseases of highway bridges such as spalling and steel corrosion will cause the bearing capacity of structural components to decrease, the durability of highway bridges will be insufficient, and the normal service life will be greatly reduced. [0003] Due to the insufficient durability of the structure, a large number of reinforced concrete structures fail early and fail to reach the specified service life. Especially for highway bridges, due t...
