Description

Anti-collision guardrail construction device and working method

Technical Field

The invention relates to the technical field of highway bridge construction, in particular to a crash barrier construction device and a working method thereof.

Background

The bridge anti-collision guardrail is positioned at two sides of the bridge, adopts the structural components of steel bars and concrete, is an important component of the bridge, not only provides safety guarantee for traveling and pedestrians, but also enables the bridge to be more attractive. The bridge anti-collision guardrail template is divided into an inner template and an outer template, the inner template is installed on the inner side of a bridge, and the outer template is installed on the high-altitude face on the outermost side. The installation and the removal of the outer template of the anti-collision guardrail are the operation which is the most difficult for constructors to operate in the construction of the anti-collision guardrail and has high safety risk in the high-altitude face construction.

The traditional construction operation mostly adopts hanging plates, hanging cages or a scaffold tube and a fastener as a simple suspension bracket, and constructors stand on the suspension tools to operate, so that the construction operation is inconvenient and unsafe; the construction method has the advantages that a plurality of construction units adopt small-sized cranes for organizing construction, and the problems of high personnel investment, high mechanical equipment cost investment, slow construction progress, unavailable effective guarantee of production safety and the like exist.

In order to solve the technical problems, patent document with Chinese patent number 202021355910.9 and bulletin day 2021.04.20 discloses a highway bridge anti-collision guardrail template dismounting construction operation trolley which comprises a steerable walking vehicle body, a truss and a working hanging basket, wherein the truss is fixedly connected to the steerable walking vehicle body, the truss comprises two brackets and a cross beam arranged at the upper ends of the brackets, the lower ends of the two brackets are fixed to the steerable walking vehicle body, and the upper ends of the two brackets are connected through a stabilizing frame; two ends of the two cross beams are respectively connected through a distance rod; the working hanging basket is respectively connected with the end parts of the two cross beams through a sliding frame, the upper end of the sliding frame is movably connected with the cross beams through a pulley bracket, and the lower end of the sliding frame is hinged with the working hanging basket; one ends of the two cross beams far away from the working hanging basket are respectively hung with a counterweight hanging block through a steel wire hanging rope.

However, according to the technical scheme disclosed in the patent document, when the construction operation trolley works, the end beam guide groove of the traveling beam transversely runs on the traveling guide rail, and the steel wire rope electric hoist on the traveling beam can be used for hoisting the template of the anti-collision guardrail and adjusting the position of the template; the template is installed or detached in such a way, so that the efficiency is low;

because the template of the anti-collision guardrail is hoisted through the steel wire rope electric hoist, the anti-collision guardrail can shake, and further needs manual adjustment, and because the quality of the steel template is large, a worker manually adjusts the template, the adjustment accuracy is limited, and the labor and the effort are wasted; although the document also discloses that the steel template can be subjected to wireless remote control operation, even though the manual adjustment is omitted in the wireless remote control operation, the steel template is subjected to fine adjustment through the adjustment of the steel wire rope electric hoist, the steel template always has the shaking condition, and the cost is low; the construction operation trolley can only provide the lifting function for the steel template and the function of adjusting the template by lifting workers through the working hanging basket;

in addition, in the traditional construction flow of the anti-collision guardrail, on one hand, when concrete is poured into the templates, the concrete in the templates can generate an outward force acting on the inner sides of the templates due to the mass and inertia of the concrete, so that the templates have a tendency of being pushed away outwards, and further the two templates can be caused to slide outwards respectively, so that the anti-collision guardrail formed by pouring is inconsistent with the design, and the quality of the anti-collision guardrail is influenced; in the prior art, the template is fixed on the two sides of the embedded steel bars by stretching the embedded steel bars, so that the fixation and stability of the template are ensured, but the template is fixed in a stretching mode, which is labor-consuming and has low efficiency; on the other hand, in traditional construction process, dismantle the template of anticollision barrier through artifical manpower, when the manual work was dismantled the template, the external force of manual work application was inhomogeneous on the template, appears external force too big easily, destroys the condition of anticollision barrier.
