Technical Field

[0001] The present invention relates to the technical field of construction site equipment, and in particular to UHPC construction site equipment and a construction method. Background Art

[0002] Ultra-high performance concrete, referred to as UHPC, is a cement-based concrete material with ultra-high strength, high toughness, high durability and excellent casting and molding properties. It is made by selecting highly active fine materials and adopting the most compact and fiber-reinforced technology. It is usually made of high-strength and tough materials such as silicate cement, silica fume, quartz powder, fine silica sand, high-efficiency water reducer, water, steel or organic fiber as raw materials.

[0003] However, the existing technology has the following shortcomings: Currently, UHPC is mainly produced and manufactured using a variety of raw materials, but since most of the existing UHPC is produced and transported by mixing stations, the performance of UHPC is directly reduced due to the influence of external environmental factors during transportation to the construction site.

A material dropping port 2131 is opened at the bottom of the lower aggregate bin 213. A vibrating plate 2181 is connected inside the vibrator 218.

[0038] Furthermore, the vibrating plate 2181 is installed on the inner wall of the lower aggregate bin 213. Through the vibration of the vibrator 218, it prevents the UHPC material from solidifying. The control boxes 216 installed on both sides of the fixing frame 211 control the heating and cooling boxes 217 to achieve temperature control of the conical guiding hopper 212.
