Problems solved by technology

Anti-collision buckets and plastic water barriers are made of EVA and polyurethane composite materials, which have the advantages of elasticity, anti-collision and wear resistance. The collision barrier can only rely on the elasticity of the anti-collision barrel to buffer the impact force, and the anti-collision ability of the protective facilities is low, which does not meet the required anti-collision level requirements, causing safety hazards to the construction area
The driven-in steel guardrail absorbs the impact energy from the vehicle through the tension and bending deformation of the beam, and has a certain degree of rigidity and toughness. Toughness and rigidity, both rigid and flexible, generally will not break, and the blocking effect is better; however, this kind of guardrail needs to drive the pillars into the ground, which requires a long construction period and will cause damage to the road surface, so it is not suitable for temporary road maintenance areas use
The concrete anti-collision pier has little damage after being hit, and can continue to be used normally without maintenance; however, these facilities have a large self-weight and are inconvenient to transport for temporary construction areas
During nighttime construction, the visibility is low, and it is difficult for the driver to find the protective facilities, which may easily lead to accidents
[0008] On the other hand, Gao Yingli et al. "Study on the Properties and Mechanism of Superhydrophobic-Self-luminous Cement-Based Composite Materials" jointly designed long-lasting luminescent materials and superhydrophobic materials to prepare superhydrophobic-self-luminous cement-based composite materials, but the reflective powder Incorporation will react with hydration products to form flocs with a porous structure, which is not conducive to the formation of the strength of cement-based materials

Embodiment 1

[0088] Super-hydrophobic self-luminous steel-concrete combination protective fence concrete base, such as figure 1 , figure 2 with image 3 , The optical fiber is pre-embedded, and then the cement-based mixture is poured. The difficulty of this method lies in the uniform distribution and fixation of the optical fiber. The concrete pier body template adopts a customized steel template. Before the template is installed, it should be cleaned and repaired. The dust and other substances on the surface of the template should be wiped off, and the surface should be polished and polished. Paint the release agent on the surface, and do not use oil that sticks to the concrete or discolors the concrete. The pre-embedded ribs of the isolation pier are exactly at the joint between the two templates. When installing the template, a sponge strip should be wrapped around the steel bar to prevent grout leakage. After the mold is installed, the steel cage is manufactured according to the requi...

Embodiment 2

[0097] The structure of the super-hydrophobic self-luminous steel-concrete combined protective fence is the same as that of Example 1, except that the construction method is as follows:

[0098] (1) Put the mixed admixture of 1600 parts of crushed stone and 1000 parts of sand into the mixer for 65s, then put in 300 parts of cement, 75 parts of luminous powder, 30 parts of reflective powder, 15 parts of kaolin (plasticity index is 13) Dry mixing for 40s, pour in tap water mixed with 4 parts of naphthalene-based superplasticizer and stir for 120s, and set the resulting concrete mixture for use;

[0099] (2) Pouring molding: Pour the concrete mixture prepared in step 1) into the steel mold, stop discharging when there is 500mm from the top, put the steel cage into the steel mold, and evenly distribute the optical fiber at a distance of 200mm from the top. Casting molding, standard curing 28 days demoulding, and then the formed concrete base;

[0100] (3) Super-hydrophobic layer: dip th...

Embodiment 3

[0132] A super-hydrophobic self-luminous steel-concrete combined protective fence, comprising: a base 1, a column 7, a protective plate 6, the base 1 is provided with perforations I, II (3, 2) in the vertical and horizontal directions, respectively, The upright post 7 passes through the vertical perforation I(3) and is fixed on the base 1, and the top end of the upright post 7 is connected to the protective plate 6.

Abstract

The invention relates to a super-hydrophobic self-luminous steel-concrete composite protective fence and a construction method. The super-hydrophobic self-luminous steel-concrete composite protectivefence comprises a concrete base; a cement pier through pipe through hole and an upright through hole are formed in the concrete base; by using an upright double-hanging mode, a transverse diaphragm isconnected to two double wave corrugated plates by using connecting bolts, and threads are arranged at the bottom of an upright; the double wave corrugated plates are connected together through splicebolts; and the upright transmits an impact force to the concrete base through a nut. The super-hydrophobic self-luminous steel-concrete composite protective fence has the beneficial effects that eachcomposition of the super-hydrophobic self-luminous steel-concrete composite protective fence adopts a splicing mode so that the deadweight of the super-hydrophobic self-luminous steel-concrete composite protective fence is small and the super-hydrophobic self-luminous steel-concrete composite protective fence is convenient to carry and use. Compared with a common temporary construction area protection mode, the super-hydrophobic self-luminous steel-concrete composite protective fence has the advantages that the bearable impact force is higher, the safety grade is enhanced, the protection to construction personnel and construction area is more excellent, the super-hydrophobic self-luminous steel-concrete composite protective fence can emit lights for a longer time at nights when there is no external power supply, a passing vehicle is prompted to reduce the accident occurrence frequency.

Description

Technical field [0001] The invention belongs to the field of high-speed protective fence manufacturing, and specifically relates to a super-hydrophobic self-luminous steel-concrete combined protective fence and a construction method. Background technique [0002] Disclosure of the background information is only intended to increase the understanding of the overall background of the present invention, and is not necessarily regarded as an acknowledgement or in any form suggesting that the information constitutes the prior art known to those of ordinary skill in the art. [0003] In recent years, with the strengthening of our country's economy and the rapid development of high-speed traffic, the demand for expressways is increasing. The expressway is a symbol of a country's development, but also a manifestation of a country's modernization. The expressway plays an important role in the entire transportation system, and its value meaning in the social operation process is irreplaceab...
