Steel bridge full-section cleaning, painting, stone spreading machine and its use

Abstract

The invention discloses a steel bridge full-section cleaning, painting, and stone-spreading assembly and disassembly machine and a use method thereof, belonging to the technical field of bridge deck restoration devices. The present invention includes the following steps: step 1, assembling the cross-section mobile frame, and installing rollers under the cross-section mobile frame, one end of which is connected to a speed-controllable tractor; step 2, installing a detachable clamping rod according to the cleaning equipment: step 3 , Cleaning: Turn on the electric high-pressure washing machine, open the winder in the cloth storage box, and press the rag on the ground to be cleaned through the rag clamp box; Step 4, remove the cleaning equipment, and build the spraying equipment: Step 5, Spray paint: The portable mobile high-pressure paint spraying machine extracts the paint from the storage box where the paint is stored through the paint pipe; step 6, remove the spraying device, and install the stone sprinkler device; step 7, spread gravel. The invention realizes mechanical repair by reducing the labor intensity of workers.

Description

technical field [0001] The invention belongs to the technical field of bridge deck repair devices, and in particular relates to a steel bridge full-section cleaning, painting, and stone-spreading assembly and disassembly machine and its use method. Background technique [0002] Bridge deck asphalt pavement has been widely used in bridge construction in recent years. Except for a few bridge deck pavements that are in good operation, most of the bridge deck pavement has defects such as rutting, cracking, and shifting. The main causes of the damage are summarized as follows: damage to the bonding layer, cracking of the pavement layer, delamination or spalling damage, and rutting. The main causes of pavement damage are: improper design of steel box girder structure, unreasonable setting of waterproof bonding layer, poor performance of pavement, detail problems during pavement construction, serious overloading and so on. The performance of epoxy asphalt concrete is greatly affec...

AI Technical Summary

Problems solved by technology

The performance of epoxy asphalt concrete is greatly affected by factors such as temperature, time, and rolling timing. There are problems such as relatively high requirements for the construction quality control system, and there are certain difficulties in actual construction.
