Problems solved by technology

Each process step needs to be completed manually, and the degree of automation is low
The main component of the planting glue is epoxy resin, which not only has a certain timeliness, but also is brittle, and it is easy to become brittle after being disturbed by external force, which affects the bonding performance.

Embodiment

[0024] like Figure 1-6 As shown, a construction method for widening a bridge based on a water milling concrete removal robot, the construction is carried out according to the following steps:

[0025] (1) Construction preparations: make preparations for bridge widening, remove debris on the original bridge surface, and ensure traffic in the construction area. According to the current status of the construction road, measure and mark the transition area, warning area, operation area and guidance line, arrange equipment and carry out construction stakeout. According to the requirements of the situation, mark the concrete removal position on the bridge deck of the old bridge 1, install the high-pressure pump water pipe on the spray gun of the water milling concrete removal robot, and connect the other end of the high-pressure water pump to the water truck, and then place the water milling concrete removal robot on the old bridge 1 to remove it At the starting position, set the ...

Abstract

The invention discloses a construction method for widening a bridge on the basis of a water-milling concrete removal robot. Construction is conducted according to the following steps of firstly, preparing for the bridge widening work, placing the water-milling concrete removal robot at the removal initial position, arranging arms of the water-milling concrete removal robot, and regulating the angle of spray guns; secondly, regulating the pressure intensity of a high-pressure water pump, and operating the water-milling concrete removal robot to remove concrete of an old bridge; thirdly, sweeping away removed concrete residues of the old bridge, and conducting strengthened welding on a reserved reinforcing steel bar of a new bridge and exposed reinforcing steel bars of the old bridge; fourthly, conducting the water spraying work on a crack between the new bridge and the old bridge through a water transporting vehicle, and pouring concrete after the crack is thoroughly wetted; fifthly, detaching a formwork on the bottom face of the old bridge, and handling the final arrangement work. In a word, the construction method has the advantages that secondary damage to the structure of the old bridge is avoided, damage to reinforcing steel bars in the old bridge is avoided, it is avoided that the bearing capacity of the widened new bridge is reduced, the service life is long, and the construction time is short.

Description

technical field [0001] The invention belongs to the field of road and bridge engineering, and relates to a construction method for widening a bridge based on a water milling concrete removal robot. Background technique [0002] In recent years, with the rapid development of my country's economy, my country's transportation industry has made great progress. However, due to the increasingly frequent movement of people and goods, the demand for transportation has surged. Bridges account for a large proportion of modern expressways. In addition, bridge widening has the characteristics of complex technology, high difficulty in implementation, and great impact on existing traffic. Therefore, the design of bridge widening has become the focus of expressway reconstruction and expansion projects. However, at the current level of technology, no matter whether it is an artificial pick or an excavator equipped with a hydraulic hammer, it will cause damage to the concrete structure, gen...
