Description

UHPC light side ditch cover plate Technical Field The utility model relates to the technical field of constructional engineering, in particular to a UHPC light side ditch cover plate. Background The side ditch cover plate is used as an important component of drainage systems of municipal roads, highways and the like, and needs to bear multiple functions of vehicle load, environmental corrosion, temperature stress and the like. The road side ditch cover plate at present is mostly made of common concrete materials, has a thick structure, is about 226 kg in dead weight, is inconvenient to install and transport, uses low-grade concrete, is easy to fall off corners, damage and the like in the transportation and installation process, is easy to generate bending deformation under repeated rolling of heavy-duty vehicles, is poor in durability, particularly uses a large amount of snow melting agent in winter, is easy to cause the cover plate to have concrete stripping, steel bar corrosion and the like, is short in service life, is poor in surface skid resistance, and is easy to cause sideslip accidents in rainy and snowy days. The Ultra-high performance concrete (UHPC for short) is a novel cement-based composite material with Ultra-high strength, high durability and good working performance, the bearing capacity of the UHPC is far greater than that of common concrete, and in addition, the UHPC has excellent impermeability, freezing resistance and chemical erosion resistance, can effectively resist the invasion of external harmful substances, and has long service life. More importantly, the UHPC has good fluidity and filling property in a fresh state, can be compactly molded under the condition of no or slight vibration, and is suitable for manufacturing components with complex shapes. Therefore, UHPC is used as a high-performance building material, and a UHPC side ditch cover plate integrating high-strength crack resistance, skid resistance and intelligent leveling can be developed by means of UHPC so as to break through the application bottleneck of the traditional technology. Disclosure of utility model In order to solve the problems in the background technology, the utility model provides the UHPC light side ditch cover plate, solves the problems of heavy weight, high maintenance cost and the like of the traditional side ditch cover plate, forms obvious technical advantages in the aspects of safety, durability, economy and the like, is beneficial to construction, and has good application prospect. The UHPC light side ditch cover plate comprises a UHPC panel, wavy stiffening ribs and a plurality of adjustable supporting bases, wherein the UHPC panel comprises an anti-slip layer, a bearing layer and an anti-cracking layer which are arranged from top to bottom, the wavy stiffening ribs are arranged at the bottom of the UHPC panel, the wavy stiffening ribs comprise wavy continuous structures which are arranged along the two sides of the length direction of the UHPC panel, a plurality of straight plate connecting ribs are connected between the two wavy continuous structures, and the plurality of supporting bases are arranged at the bottom of the wavy stiffening ribs and are used for adjusting the height of the cover plate. Optionally, the anti-skid layer is a UHPC layer doped with carborundum aggregate with the particle size of 0.5-1mm, the bearing layer is a UHPC layer doped with stainless steel fibers and organic fibers, and the anti-cracking layer is a UHPC layer embedded with glass fiber mesh cloth. Optionally, a triangular transition area is arranged at the joint of the wavy stiffening rib and the UHPC panel.
