Small village highway bridge reconstruction and reinforcement method

Abstract

The invention discloses a small village highway bridge reconstruction and reinforcement method. A reinforcement module is included. The reinforcement module comprises an under-bridge reinforcement module and an on-bridge reinforcement module. The under-bridge reinforcement module comprises a water and soil protection module, a pile foundation enlargement module and a pile cap repairing module. Theon-bridge reinforcement module comprises a bridge deck expansion module, a bridge deck strengthening module and a monitoring module. The water and soil protection module comprises a gabion protectionmodule and an embedded wall building module. The pile foundation enlargement module comprises a cleaning module, a dabbing module and a strengthening module. The embedded wall building module comprises an embedded wall. The pile cap repairing module comprises a new pile cap which is built under water and an old pile cap. According to the invention, scouring and damage to a pile foundation by currents are avoided, forced sedimentation is conducted under piers, thus water and soil are effectively conserved, the pile foundation is avoided being emptied, the cost of reinforcement is lowered, thepile foundation is effectively improved, the weight of passing vehicles is detected, damage to the bridge by overweight vehicles is effectively avoided, and thus the maintenance cost of the bridge islowered.

Description

technical field [0001] The invention relates to the technical field of bridge reinforcement, in particular to a method for rebuilding and reinforcing small rural road bridges. Background technique [0002] With the rapid development of rural transportation in my country, bridges on rural roads are burdened with very heavy traffic loads and heavy traffic volume. The level of construction technology is low, the equipment, means and materials are outdated, the long-term lag in operation and management after the bridge is put into operation, the construction of management system and team building have been neglected for a long time, the management and maintenance fees have been occupied and embezzled, and the operating vehicles have been generally overloaded and seriously overloaded for a long time. Containment has caused a large number of rural road bridges to suffer from various large and small diseases, such as bridge deck damage, railing breakage, expansion joint damage, bridg...

Problems solved by technology

[0002] With the rapid development of rural transportation in my country, bridges on rural roads are burdened with very heavy traffic loads and heavy traffic volume. The level of construction technology is low, the equipment, means and materials are outdated, the long-term lag in operation and management after the bridge is put into operation, the construction of management system and team building have been neglected for a long time, the management and maintenance fees have been occupied and embezzled, and the operating vehicles have been generally overloaded and seriously overloaded for a long time. Containment has caused a large number of rural road bridges to suffer from various large and small diseases, such as bridge deck damage, railing breakage, expansion joint damage, bridge head jumping, concrete spalling, bridge head subgrade erosion, etc., which have destroyed the normal operation of the bridge. In good condition, it not only greatly shortens the service life of bridges, but some have already threatened the safety of passing people and vehicles and become dangerous bridges. Therefore, it is necessary to renovate and strengthen rural road bridges.
