TECHNICAL FIELD
[0001] The utility model relates to the technical field of UHPC leveling film covering, especially to a UHPC paving intelligent variable-width paving equipment. BACKGROUND
[0002] With the rapid development of China's economy, the construction of expressways is constantly improving, providing people with a more convenient and efficient comprehensive transportation network. As a key component of expressways, bridges play an important role in ensuring smooth traffic and improving driving safety. The bridge deck pavement layer, as the wearing layer, directly bears the repeated action of vehicle load and is easily affected by the external environment, so it is a key control point of bridge engineering quality and plays an important role in maintaining the safety and stability of the superstructure. Therefore, how to avoid quality defects in the bridge deck and strictly control the construction quality of the bridge deck pavement layer is particularly important.
[0003] By introducing the use of a paver, the construction unit can avoid various problems faced by manual paving of asphalt concrete pavement. Not only does it liberate most of the manpower and resources, but it also improves the safety level and paving quality of the road. At the same time, due to the uniform paving of the machinery, the service life of the road is greatly extended. The many advantages of construction are unmatched by manual labor.
[0004] Currently, in the expressway construction industry in China, there are two types of pavers widely used, namely caterpillar type and tire type. The two types of machines are designed to cope with different construction environments. Among them, the caterpillar type paver belongs to a large paver. Due to the design characteristics of the caterpillar, it has the advantages of high paving quality, wide working surface, and high working efficiency. Compared with the tire type paver, the caterpillar machine has better performance in all aspects. However, this equipment also has limitations, mainly poor mobility, only capable of paving on straight roads, poor performance on curved roads, and high requirements for the construction environment of the caterpillar type paver, with many components, prone to mechanical problems during use. In addition, the component cost is expensive, and the mechanical maintenance and repair are difficult. Generally, the caterpillar type is only used for trunk road construction or road paving work on wide straight roads. The tire type paver belongs to a small or medium-sized paver, which has high mobility. Compared with the caterpillar type paver, the working quality on curved roads is significantly better. However, due to the size of the machine, the paving width is small, and due to the small weight, the paving road flatness is significantly inferior to the caterpillar type paver. Generally, the tire type paver is mainly used for highway curve construction and post-maintenance and repair work of expressways. These two types of pavers use diesel as fuel. Currently, the paver market in China is mostly occupied by imported pavers from abroad, and compared with domestic pavers, their technical reliability is significantly better. However, with continuous technological innovation, some domestic brands have gradually opened up the market and have a certain advantage in price.
[0005] In summary, the conventional paver generally cannot pave the bridge deck with variable width. Therefore, a UHPC paving intelligent variable width paving equipment capable of solving the above problems is needed. SUMMARY
