Description

TECHNICAL FIELD

[0002] In the face of natural disasters and public emergencies, it is of great significance to establish hidden protective engineering in various cities to protect the safety of people's life and property. At present, the materials widely used in protective engineering mainly include single materials such as soil, wood, masonry, ordinary concrete and steel, and composite materials taking rubber resin as a matrix and high-strength polyethylene fiber as a reinforcing body, but all have certain limitations: the strength of soil, wood and masonry is relatively low, and the protective ability is very limited, which is often used in secondary parts or assisted with other materials; ordinary concrete has certain strength, toughness and damage resistance, but due to the impact and dynamic load of the protective engineering, the dynamic performance of ordinary concrete is insufficient to meet the increasing protection requirements; steel and composite materials are relatively expensive and cannot be widely applied.

[0003] And due to the uncertainty of natural disasters and public emergencies, it is impossible to establish protective engineering in all positions in the city, and often the protective engineering is constructed after the occurrence of natural disasters and public emergencies. The existing concrete protective engineering is mostly cast-in-place structure, and the construction period is long, so it is difficult to meet the tight schedule requirement for temporary protective structure. Therefore, the protective engineering often adopts prefabricated parts for construction, but single prefabricated part cannot meet the diversified protection requirements. SUMMARY
