Device for reducing cracks of concrete at periphery of road well cover

Abstract

The invention discloses a device for reducing cracks of concrete at the periphery of a road well cover. The device comprises a well cylinder, a leveling layer, a well ring and the well cover. The wellcover is rotationally connected with the well ring through a pin shaft. The well ring is fixedly connected with the upper end of the well cylinder through the leveling layer. The well cylinder and the leveling layer are made of concrete. The concrete of the well cylinder and the upper end of the leveling layer internally comprises a crack-proof device. The crack-proof device comprises two crack-proof balls and a connecting rod. The two ends of the connecting rod are connected with the crack-proof balls correspondingly. Each crack-proof ball internally comprises a hollow steel ball. Each hollow steel ball is filled with steel wires and a binder. Steel wires are in disorder connection with the corresponding hollow steel ball. The binder contains carbon fiber. An outer layer of each hollow steel ball is connected with a first concrete layer, the elasticity of the concrete can be improved, energy generated by vibration of the well cover and the well ring can be absorbed, and meanwhile, the cracks in the concrete can be restored.

Description

Technical field [0001] The invention relates to the field of devices for reducing concrete cracking around road manhole covers, and more specifically, to a device for reducing concrete cracking around road manhole covers. Background technique [0002] The construction of municipal pipelines in a city is the foundation for the normal operation of a city. We can see rainwater manhole covers and sewage manhole covers everywhere on urban roads. Conventional well structures include well body foundation, well chamber, shaft, leveling layer, well circle and manhole cover. The repeated high-speed rolling of the manhole cover produces vibrations when the manhole cover hits the well circle. Long-term impact can easily separate the well circle from the surrounding concrete. Gradually, the concrete around the well circle produces cracks, and once the concrete cracks, the manhole cover and the well There will be a lot of noise under the rolling of vehicles between the circles, which will affe...

Problems solved by technology

[0002] The city's municipal pipeline construction is the basis for the normal operation of a city. We can see rainwater manhole covers and sewage manhole covers everywhere on urban roads. The conventional well structure includes well body foundation, well chamber, well shaft, leveling layer, well ring and manhole cover. Due to vehicles Repeated high-speed rolling will cause the well cover to hit the well circle and vibrate. The long-term impact will easily separate the well circle from the surrounding concrete, and gradually the concrete around the well circle will crack. There will be a lot of noise under the rolling of vehicles between the circles, which will affect the lives of surrounding residents at night. Therefore, how to reduce the cracking of the concrete on the road due to the vibration of the manhole cover is very important.
