Problems solved by technology

[0002] With the rapid development of my country's road transportation industry, the traffic flow and the surge in the middle of the week have made the quality requirements of municipal roads and highways higher and higher. However, many roads often suffer from subsidence after a period of design, construction and operation. , cracks and other structural damage, at this time, measures such as repairing the road often require road closure construction, which can easily lead to traffic obstruction and confusion, and after repairing here, if the repair is not appropriate, it is easy to sink in the original cracks or subsidence. Cracks and subsidence reappeared at the site, wreaking havoc on the use of traffic roads

Abstract

The invention discloses a pavement material based on a three-dimensional reconstructed model. The pavement material is prepared from the following components in parts by weight: 100 parts of sand, 5 to 9 parts of quartz sand powder, 5 to 10 parts of expanded perlite powder, 40 to 60 parts of cement, 10 to 20 parts of fiber mixture, 3 to 4 parts of water absorption resin, 1 to 2 parts of water reducing agent, and 30 to 40 parts of water. The pavement material disclosed by the invention is a pavement material with appropriate strength and hardness obtained by analyzing and processing a place to be repaired by virtue of a three-dimensional rebuilding technology, the pavement can be rapidly repaired by virtue of grouting, and the influence of the long-time repairing on the traffic can be solved.

Description

technical field [0001] The invention relates to a pavement material based on a three-dimensional reconstruction model. Background technique [0002] With the rapid development of my country's road transportation industry, the traffic flow and the surge in the middle of the week have made the quality requirements of municipal roads and highways higher and higher. However, many roads often suffer from subsidence after a period of design, construction and operation. , cracks and other structural damage, at this time, measures such as repairing the road often require road closure construction, which can easily lead to traffic obstruction and confusion, and after repairing here, if the repair is not appropriate, it is easy to sink in the original cracks or subsidence. Cracks and subsidence reappeared at the site, causing serious damage to the use of traffic roads. The 3D reconstruction technology is to obtain the data image of the scene object through the camera, analyze and proce...
