Concrete pavement automatic spraying and maintaining device for bridge construction

Abstract

The invention discloses an automatic spray maintenance device for concrete pavement used in bridge construction, which comprises a pavement foundation and a mounting seat installed on the pavement foundation. The middle part of the guide wheel is connected with the traction shaft, the right end of the traction shaft is connected with the drawbar, the upper end of the right mounting seat is connected with the right guide rail, the upper end of the right guide rail is connected with the right guide wheel, the middle part of the right guide wheel is connected with the driven shaft, and the left end of the driven shaft is connected with the There is a driven wheel, the upper end of the driven wheel is connected to the driving wheel through a chain, the right end of the driving wheel is connected to the driving shaft, the right end of the driving shaft is connected to the traction motor, a connecting plate is installed between the traction rod and the left fixed frame, and a storage battery is installed on the upper end of the connecting plate. water tank. The present invention realizes the automatic spray maintenance of the bridge concrete pavement, increases the maintenance quality of the pavement, avoids manual sprinkler spraying at the same time, reduces the labor intensity of the staff, and realizes the automatic spraying of the pavement with low cost. .

Description

technical field [0001] The invention relates to the technical field of bridge pavement construction equipment, in particular to an automatic spray maintenance device for concrete pavement used in bridge construction. Background technique [0002] Road bridges are generally composed of several parts such as roadbed, road surface, bridge, tunnel engineering and traffic engineering facilities. Pavement usually consists of pavement bodies, shoulders, curbs, and medians. Among them, the pavement body can be divided into carriageway, sidewalk and curb belt in the horizontal direction, and the pavement body can be divided into surface layer, base layer, cushion layer or connecting layer according to the structural level from top to bottom. [0003] At present, in the construction process of cast-in-place bridges, most of them use artificial watering to maintain the concrete of cast-in-place bridge decks according to conventional methods. There are mainly the following problems in...

AI Technical Summary

Problems solved by technology

There are mainly the following problems in the maintenance of bridges by artificial watering: (1) Artificial watering maintenance is greatly affected by human factors, and problems such as untimely maintenance, insufficient maintenance time, and improper maintenance methods often occur, resulting in shrinkage cracks and partial bridges. Leakage of maintenance occurs in the area, forming a common quality problem; (2) Due to the high terrain of the bridge, especially the bridge deck across the river and sea, it is greatly affected by the wind speed, and the air-drying effect is serious. The water loss inside the concrete is relatively fast, and the moisturizing effect is poor. (3 ) Manual sprinkling maintenance during the 7-day curing period of concrete requires a lot of maintenance labor and low economic benefits. If a large amount of precipitation occurs during the maintenance period, other measures are usually required, which further increases the labor workload
