Well lid periphery road surface protection device used for concrete road surface

Abstract

The invention relates to the technical field of roads, in particular to a well lid periphery road surface protection device used for the concrete road surface. The well lid periphery road surface protection device comprises universal wheels, control mechanisms, supporting columns, a box body, a collecting mechanism, fixing mechanisms, enclosure mechanisms, a partition plate, a storage battery, a compression mechanism, an electromagnetic valve, a cooling mechanism and damping mechanisms. When the temperature in concrete is high, the control mechanism opens the electromagnetic valve, the coolingmechanism sprays water on the surface of the concrete in an atomizing mode to decrease the temperature of the concrete, the water is not directly sprayed on the surface of the concrete, and the situation that the water impacts the surface of the concrete is prevented. The enclosure mechanisms are arranged on the periphery of the concrete to enable the uncongealed concrete to be enclosed, sunlightand rainwater are prevented from being directly sprayed on the surface of the concrete, and thus the concrete is protected. The damping mechanisms are arranged on the periphery of the concrete, whena vehicle passes by the concrete, the ground transmits vibration to enable the damping mechanisms to vibrate, vibrating energy is reduced, thus the concrete is damped, thus the situation that due to ground vibration, the uncongealed concrete greatly vibrates, and thus the concrete is cracked is prevented.

Description

technical field [0001] The invention relates to the technical field of roads, in particular to a road protection device for the periphery of a manhole cover on a concrete road. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] After pouring concrete, the hydration reaction of cement concrete will release a lot of heat, especially the tricalcium aluminate in the cement component, the hydration reaction speed is the fastest, and the heat of hydration will be very high, resulting in a large temperature difference between the inside and outside of the concr...

[0003] After pouring concrete, the hydration reaction of cement concrete will release a lot of heat, especially the tricalcium aluminate in the cement component, the hydration reaction speed is the fastest, and the heat of hydration will be very high, resulting in a large temperature difference between the inside and outside of the concrete, making the concrete Cracking; and when pouring concrete on the manhole cover, vehicles often pass by the side of the manhole cover, causing a certain vibration on the bottom surface, which causes the poured concrete to crack
