Due to the generally poor road conditions in rural areas at night, traffic accidents are very likely to occur.

[0023] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be understood as limiting the present invention. Various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
[0024] The utility model discloses a self-absorption luminous concrete structure, comprising a light-emitting and light-transmitting column 4 and a concrete body 3, wherein the light-emitting and light-transmitting column (reference Figure 1 ) includes a core and an outer shell, the core is a light-transmitting inner core 1, the outer shell is a luminous cement stone 2 arranged on the outer surface of the light-transmitting inner core, and the thickness of the outer shell is 1-2 times the radius of the light-transmitting inner core; the luminous-light-transmitting column is embedded in the concrete body.
[0025] The luminous cement stone is formed by compounding white cement, water and long afterglow luminous material into a pure paste and then solidifying.
[0026] After the light-transmitting inner core is immersed in the clean slurry, it is fished out and waited for 1 hour before being immersed in the clean slurry again. The operation is repeated 2-3 times and then placed in a ventilated place for about 6-8 hours to form a light-transmitting column.
[0027] Then prepare a mold and insert a "light-emitting-transmitting column" at a specified position in the mold. After the spatial layout is fixed, pour the concrete mortar into the mold and vibrate and cure at a specified rate, and then grind it roughly to obtain a concrete body 3 wrapped with the light-emitting-transmitting column; seal the concrete body with epoxy resin to obtain a self-absorbing energy-luminous concrete structure.
[0028] The long afterglow luminescent material comprises a light absorber, a luminescent agent, a photochemical buffer, etc. Preferably, the ultraviolet long afterglow material is made of barium germanate as a matrix, Bi ions as luminescent centers, and trivalent rare earth ions. This material recycles the light absorbed by the concrete and transmits it through the light-transmitting inner core, thereby greatly improving the luminous intensity of the light-transmitting concrete.
[0029] The light-transmitting inner core is made of light-transmitting material, such as optical fiber. A single optical fiber can be used or a plurality of optical fibers can be woven together to form the light-transmitting inner core. The optical fiber uses a plastic optical fiber with a core diameter of 100-3000 μm.
[0030] Example 1
[0031] The present embodiment discloses a self-energy luminous concrete road marking, wherein the road marking is laid out in an array using a number of luminous and light-transmitting columns in a direction perpendicular to the road surface. The array laying area is the length and width area of the road marking required by the specification. A concrete body 3 is arranged in the adjacent spaces of all the luminous and light-transmitting columns, and an epoxy resin sealing layer is arranged on the upper surface layer of the concrete body 3.
[0032] In this embodiment, the light-transmitting core 1 of the light-emitting-transmitting column is woven from two plastic optical fibers with a core diameter of 3000 μm, and the outer shell is a luminous cement stone 2 arranged on the outer surface of the light-transmitting core, and the thickness of the outer shell is twice the radius of the light-transmitting core.
[0033] Compared with similar products, it is more wear-resistant and has a lower construction difficulty coefficient. It absorbs visible light under daytime lighting conditions and emits light at night without additional light source. It is aimed at the poor road conditions in rural areas at night, which is prone to traffic problems. When paving the road, first pour ordinary concrete and then dig out a preset space at the marking line. Figure 2 This is the side view of the road. After the spatial layout is fixed, the light-transmitting columns are installed in sequence along the length of each zebra crossing, and then the concrete mortar is poured and completed after solidification.
[0034] The specific implementation process is as follows:
[0035] 1. Mix 50-60 parts of white cement, 25-30 parts of water and 15-20 parts of long afterglow luminescent material, and prepare a slurry by stirring and vibrating.
[0036] 2. Dip the plastic optical fiber into the clean slurry one by one, take it out, wait for 1 hour, and then dip it into the clean slurry again. Repeat the operation 2-3 times, place it in a ventilated place for about 6-8 hours to make a light-transmitting column. It is white during the day and lights up at night.
[0037] 3. Prepare a preset road marking groove, insert the light-emitting and light-transmitting columns evenly into the semi-dry ordinary concrete, fix the spatial layout, install the light-emitting and light-transmitting columns 4 in sequence along the length direction of each zebra crossing, pour concrete mortar, and obtain the concrete body 3 wrapping the light-emitting and light-transmitting columns. After laying the epoxy resin sealing layer outside the concrete body 3 wrapping the light-emitting and light-transmitting columns, maintain it for seven days, and complete the self-absorbing energy-luminous concrete road marking after solidification.
[0038] According to experimental analysis, the road marking of this embodiment has a luminous brightness of about 550mcd at night when the lighting time is 10 hours per day; 520mcd at night when the lighting time is 8 hours; 500mcd at night when the lighting time is 6 hours; and 470mcd at night when the lighting time is 4 hours. The luminous duration can reach 8-12h, and the performance reaches 300% of the national road marking brightness standard.
[0039] Example 2
[0040] This embodiment discloses a self-absorbing energy luminous concrete emergency sign (the side length of the triangular emergency sign is 70-80 cm, and it is combined with the common road warning signs to solve the problem of low visibility at night. The emergency sign is a triangular concrete plate (see Figure 3 ).
[0041] In the mold of the emergency sign, light-transmitting columns are arranged along the thickness direction, and the distance between adjacent light-transmitting columns (the distance is calculated as the length of the line connecting the centers of adjacent light-transmitting columns) is 1-2 times the diameter of the light-transmitting columns. The patterns required to be lit are assembled, and light-transmitting columns with small-diameter light-transmitting cores are used in the fine pattern parts, and light-transmitting columns with large-diameter light-transmitting cores are arranged on the edge of the emergency sign. Figure 3 In the middle is a triangular sign, in which the fine pattern part is the "!" area. A relatively small inner core-size light-transmitting column is set to make the pattern display more accurate and vivid.
[0042] In this embodiment, the light-transmitting inner core used in the edge area is woven from two optical fibers with a core diameter of 2 mm, and the light-transmitting inner core of the fine pattern portion is formed by a single optical fiber with a core diameter of 1 mm.
[0043] After installing the preset pattern of the light-transmitting column 4, pour concrete mortar in the mold, and after solidification, complete the self-absorbing and luminous concrete board sign. The internal light-transmitting core can transmit the visible light absorbed by the long afterglow luminous material in the concrete board to the surface, forming the preset indication content, self-luminous at night, and achieving the preset effect.
[0044] Anything not described in the present invention is applicable to the prior art.
