Ultrahigh-performance concrete well lid for municipal and electric power engineering and manufacturing technique of ultrahigh-performance concrete well lid

Abstract

The invention relates to an ultrahigh-performance concrete well lid for municipal and electric power engineering and a manufacturing technique of the ultrahigh-performance concrete well lid. The ultrahigh-performance concrete well lid comprises an ultrahigh-performance concrete well lid body and a well lid steel hoop wrapping the periphery of the concrete well lid body. The concrete well lid body is composed of an upper circular truncated cone-shaped well lid structure and a lower ribbed structure and formed by pouring ultrahigh-performance concrete through an integral mold at a time. The circular truncated cone-shaped well lid structure is of a big-end-up structure with the upper surface being a plane. The well lid steel hoop is of a big-end-up circular ring-shaped structure. The vertical height of the well lid steel hoop is identical to the height of the circular truncated cone-shaped well lid structure. According to the ultrahigh-performance concrete well lid and the manufacturing technique thereof, by utilizing the material properties including high strength, high toughness and high durability of the ultrahigh-performance concrete, the structural dimension of the well lid can be effectively decreased, then the dead weight is reduced, the impact resistance of the well lid is improved, the service life of the well lid is prolonged, and noise pollution and using cost in the using process are reduced. The ultrahigh-performance concrete well lid is suitable for municipal engineering construction, the problem of current urban road well lids can be solved, and the functions of protecting the environment and beautifying the environment are achieved.

Description

[0001] Technical field: [0002] The invention relates to the technical field of civil engineering, in particular to an ultra-high-performance concrete manhole cover structure used in municipal engineering. [0003] Background technique: [0004] Manhole covers in municipal engineering are generally used to cover deep road wells to prevent people or objects from falling, and have become an indispensable part of urban roads. At present, traditional manhole covers are generally divided into metal manhole covers and non-metal manhole covers. Among them, metal manhole covers have the disadvantages of high manufacturing cost, noise pollution and poor anti-theft performance, while non-metal manhole covers have the disadvantages of heavy structure, low bearing capacity, impact resistance and fatigue performance. Poor and short service life and other shortcomings. [0005] Ultra-high performance concrete is a new type of cement-based composite material with ultra-high strength, high t...
