Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building engineering, concretely relates to a steel-UHPC combined material bin partition wall for station broken stone. BACKGROUND

[0002] In the process of highway construction, the station broken stone bin is an indispensable temporary construction, which is used for storing raw construction materials and materials. Among them, the partition wall is the main structure inside the station broken stone bin, which is used to separate different types of materials. Although the construction volume of the partition wall is large and the cost and time are long, there is currently a lack of unified and clear construction standard. Generally, it follows the conventional or empirical method, using a double-layer reinforced concrete partition wall with a thickness of 50cm or a corrugated steel plate, which faces the following technical problems:

[0003] The double-layer reinforced concrete partition wall is only suitable for long-term projects with few types of materials. For projects with many types of materials, the increase in the number of partition walls in the bin will significantly increase the space occupied by the partition walls, severely squeezing the material storage space. Moreover, the construction period of the reinforced concrete partition wall is too long, generally requiring 2-3 months, which is naturally contradictory to the period and construction planning of highway construction. In addition, the reinforced concrete partition wall can only be demolished after use and cannot be reused, resulting in economic losses of up to one million yuan.

[0004] Although the corrugated steel plate can effectively save the internal space of the bin as a partition wall material. However, the corners and connections of the corrugated plate are easily damaged during assembly and disassembly. In addition, factors such as structural deformation of the corrugated plate, damage to the main structure of the steel plate, and mixing of materials, the reuse efficiency of the corrugated plate is very low, which does not match the design intention and production cost.

[0005] For the two technical solutions mentioned above, it is found that the use of a combined structure of steel-UHPC can relatively achieve low space occupancy, high reuse rate, and low economic cost. However, the UHPC product prepared from the existing graded raw materials is mainly used in long-life, high-load, and high-performance scenarios such as pavements and bridge decks, and cannot be applied to the field of bin partition walls. Therefore, a partition wall structure that can be quickly constructed, dismantled, reused, and occupies a small space needs to be developed. INVENTION CONTENTS
