Bamboo curtain-concrete prefabricated component panels and prefabricated components and their optimal size determination method

Abstract

The invention provides a bamboo skin curtain-concrete prefabricated component which is economical, environment-friendly and convenient to construct. According to the bamboo skin curtain-concrete prefabricated component, the basic mechanical mechanism that tree roots grow and spall a road surface is considered, it is considered that bamboo materials have the good rift grain tensile performance and are environment-friendly, economical and reproducible, and the pull crack effect of growing of the tree roots on the road surface is resisted through the rift grain tensile performance of the bamboo materials. The road surface is prevented from being spalled by the tree roots by embedding the prefabricated component. The bamboo skin curtain-concrete prefabricated component is arranged between the concrete road surface and pure soil and comprises a concrete prefabricated component body and a bamboo skin curtain layer. The concrete prefabricated component body is in a basket shape, and the bottom face is arranged upwards, is in contact with the concrete road surface and is used for bearing loads of the concrete road surface on the bottom face; and the bamboo skin curtain layer is matched with the top face of the concrete prefabricated component body, is fixedly connected with the top face of the concrete prefabricated component body, is in contact with the pure soil and is used for buffering extrusion, caused by growing of the tree roots, on the road surface.

Description

technical field

[0001] The invention relates to a bamboo curtain-concrete prefabricated component board, a prefabricated component and a method for determining the optimal size thereof. Background technique

[0002] In the natural state, the distribution range of the tree root system in the horizontal direction is usually slightly larger than the vertical projection of the crown. As the street tree continues to grow, its root system will continue to grow deep into the soil, and at the same time, it will continue to spread and squeeze to the surrounding area. It is easy to cause swelling and cracking of the road surface. In recent years, there are more and more pavement failures caused by concrete pavement being cracked by tree roots. This problem affects the traffic safety of vehicles and pedestrians, increases the cost of road maintenance and repairs, causes waste of resources, and is not conducive to the harmonious coexistence of human activities and the natural environme...
