Description

Geotechnical cloth positioning device for concrete guardrail maintenance Technical Field The utility model relates to the technical field of geotextile positioning, in particular to a geotextile positioning device for concrete guardrail maintenance. Background The maintenance of the bridge concrete guardrail is the key for ensuring the durability and the safety of the bridge concrete guardrail, the maintenance of the bridge concrete guardrail is started from various aspects such as early moisture preservation, crack control, waterproof treatment and the like, the long-term safety and the durability of the bridge concrete guardrail are ensured by combining with the periodic inspection and maintenance, the high-temperature, dry and rainy environments in summer bring higher requirements to the maintenance of the bridge concrete guardrail, and the maintenance of the bridge concrete guardrail in summer is critical to the maintenance of the durability, the safety and the economy of the bridge concrete guardrail. Through measures such as moisturizing, temperature control, waterproof and rust prevention, challenges such as high temperature, raininess and ultraviolet rays in summer can be effectively met, the service life of the guardrail is prolonged, and driving safety is guaranteed. The high-temperature moisture preservation in summer is extremely important for controlling concrete strength and early cracks, and the traditional moisture preservation adopts a film or geotextile water spraying and moisture preservation process for the surface of the anti-collision guardrail, and the geotextile is extremely easy to generate a phenomenon of not being attached to the surface of the guardrail under the action of wind power and the like due to the influence of external environment, so that the moisture preservation effect is poor. Disclosure of utility model The utility model provides a geotextile positioning device for concrete guardrail maintenance, which can overcome certain or certain defects in the prior art. The geotechnical cloth positioning device for concrete guardrail maintenance comprises a device main body, wherein the device main body comprises a rotating shaft, a first positioning piece and a second positioning piece which are mutually hinged are arranged at the rotating shaft, the first positioning piece is provided with a first attaching part attached to the outer wall of the outer side of the concrete guardrail, and the second positioning piece is provided with a second attaching part attached to the outer wall of the inner side of the concrete guardrail; The first locating piece and the second locating piece department all are equipped with the counterweight, and the counterweight is used for providing first locating piece and second locating piece along pivot pivoted trend in opposite directions to realize the independent laminating of first laminating portion and the outside outer wall of concrete guardrail and second laminating portion and the inboard outer wall of concrete guardrail.
