Repair technology of bridge pavement

Abstract

The invention discloses a repair technology of a bridge pavement. The repair technology comprises the steps of S1, site survey, wherein the damaged pavement is subjected to the site survey; S2, sealing of half a bridge deck construction area, wherein firstly, a half-side area of a bridge is sealed; S3, concrete digging, wherein a groove is formed through an excavator; S4, locating and welding of an expansion joint, wherein a segmented spot-welding fastening method is adopted; S5, concrete casting, wherein a two-side symmetric continuous one-time concrete casting mode is adopted; S6, concrete maintenance, wherein after concrete is casted, plastic film is adopted for covering; S7, sealing of the other half the bridge deck construction area, wherein after half a bridge deck is repaired, the other half the bridge deck is sealed, and the construction steps are repeated; S8, detection, wherein the detection is conducted to determine that a pressed road groove and a section are consistent with a road camber, the surface is flat, and corrugated fluctuation and an obvious wheel track do not exist. The process is perfected, a vehicle can be allowed to pass when the pavement is repaired, normal transportation is guaranteed, the repaired pavement can be maintained, the pavement is prevented from being damaged again within a short time, and manpower and financial resources are saved.

Description

technical field [0001] The invention relates to the technical field of road surface repair technology, in particular to a bridge road surface repair technology. Background technique [0002] At present, the traditional pavement repair process is too random and simple. It does not pay enough attention to the pretreatment and advanced treatment of the road surface. The degree of treatment is not rigorous enough. The indicators required for the pavement caused the repaired pavement to still fall off, crack or be damaged shortly after use. The traditional repair process obviously failed to achieve the repair effect, resulting in a waste of manpower, material and financial resources. At the same time, it also caused Secondary damage to the pavement. [0003] After retrieval, the Chinese patent authorization announcement number is CN103882789A, which discloses a road or bridge pavement repair process, including removing the carbonized layer; digging; cleaning waste; coating the p...
