Concrete maintenance device for highway project construction in winter

Abstract

The invention discloses a concrete maintenance device for highway project construction in winter, comprising a water spraying beam and two support foot stools, wherein several movement wheels are arranged at the bottom of the support foot stools evenly; first frame bars are arranged on the left and right sides of the top adjacent ends of the two support foot stools symmetrically; a second frame bar is arranged at the middle of the adjacent ends of the two support foot stools; guiding rails are formed at the top ends of the first frame bars; a lead screw is formed at the top end of the second frame bar; first sliding blocks are arranged on the left and right sides of the bottom of the water spraying device symmetrically; several nozzles are arranged at the bottom of the water spraying device evenly; a water tank and an observation seat are arranged at the top end of the water spraying beam; a heating resistance is arranged at the bottom of the inner cavity of the water tank; the bottomof one side end of the water tank is in through connection with a water pipe. According to the invention, the concrete curing device drives the water spraying beam to move forward and backward along the guiding rails through a motor, and meanwhile, under the effect of the movement wheels, the device moves along the direction paved by the highway, so that the road is completely sprayed for maintenance, and there is no road without maintenance.

Description

technical field [0001] The invention relates to the technical field of concrete pouring, in particular to a maintenance device for concrete in winter road engineering construction. Background technique [0002] The literal meaning of highway is public road, public transportation road, many vehicles such as automobiles, bicycles, rickshaws, horse-drawn carriages and pedestrians can walk, of course, different roads have different restrictions. It is also called Malu among the people, such as the usage in "Malu Angel", which is not limited to the exclusive use of horses. [0003] There is a difference between general roads and automobile-only roads. The latter has more and more road grades, so there are two specifications for secondary roads. [0004] Due to the development of automobiles and road construction technology, roads have developed different levels. Road classification: There are different systems of classification. The "Technical Standards for Highway Engineering...

AI Technical Summary

Problems solved by technology

Due to the relatively large area of ​​road construction, the water flow is difficult to be fully uniform, and effective maintenance cannot be carried out, and the newly poured concrete is in a rapid hydration period, with a rapid temperature rise and high surface temperature. At this time, the on-site river is directly used for maintenance. The surface temperature of concrete is high, the temperature difference is large, and the instantaneous cold shock stress is too large, especially in winter, this kind of cold shock stress is greater. For early low-strength concrete, the large cold shock stress is easy to produce hidden cold shock cracks , have adverse effects and reduce the overall safety and stability of the concrete structure
