TECHNICAL FIELD

[0001] The utility model relates to the technical field of bridge pier concrete maintenance, especially relates to a bridge pier automatic maintenance device based on template. BACKGROUND

[0002] In addition to the quality of the concrete mixture, the post-cast concrete is carefully maintained, which is an important means to improve the early and final mechanical properties of the concrete, ensure the impermeability and durability of the concrete, and other indicators; when the maintenance is not in place, the surface of the concrete will form dry shrinkage and temperature cracks, and when the surface layer of the concrete has gaps and cracks, the internal steel bars will easily rust, and when the concrete cracks reach a certain width and depth, the service life of the entire reinforced concrete structure will be affected.

[0003] At present, the maintenance of concrete mainly includes template maintenance, water spraying maintenance, brushing maintenance agent maintenance and film covering maintenance; the template maintenance is convenient and simple to operate, but occupies the template for a long time, which is not conducive to the turnover use of the template, and is not suitable for projects with high construction period requirements; the water spraying maintenance is a simple, easy-to-operate, economical and practical maintenance method, which is relatively easy for low bridge pier maintenance, but relatively difficult for high pier maintenance, and the traditional manual water spraying has the problems of uneven and untimely moisture retention, resulting in dry-wet alternation, local excess or insufficient maintenance during the concrete maintenance process; the brushing maintenance agent is convenient to use and has good maintenance effect, but the maintenance agent contains chlorides and sulfates harmful to the environment, and the method has high cost; the film covering maintenance is difficult to fix and easy to damage, and the operation of high pier is difficult, resulting in poor maintenance effect of the bridge pier. UTILITY MODEL CONTENTS

[0004] To solve the above technical problems, the purpose of the utility model is to provide a bridge pier automatic maintenance device based on a template.

[0005] To achieve the above-mentioned purposes, the technical scheme of the utility model is as follows:

[0006] A bridge pier automatic maintenance device based on a template, the bridge pier automatic maintenance device has a steel template used for bridge pier construction; the steel template is a cylindrical structure; a high-temperature-resistant water spraying hose is arranged on the outer side of the bottom end of the steel template in a ring shape, and one atomizing nozzle is arranged every 10° / 20cm on the high-temperature-resistant water spraying hose.

[0007] The steel template has a connecting hole through which the high-temperature-resistant water spraying hose passes; the connecting hole is a plurality of holes distributed along the circumference.

[0008] Compared with the prior art, the utility model has the advantages of:

[0009] 1、The utility model discloses a template self -owned water -spraying hose is used to the maintenance of concrete, replaces the manual direct watering maintenance, and it is a safe and economic method for high pier, reduces the frequency of the construction personnel because of watering and goes up and down the scaffold, effectively reduces the occurrence of safety accidents, and reduces the labor cost because of watering and produces.

[0010] 2、The utility model discloses the maintenance of concrete is carried out to the spraying technology, can be according to the temperature and humidity of concrete surface in time to the spraying maintenance of concrete, guarantees the maintenance quality, compared with direct watering maintenance, this method water consumption reduces greatly, saves water and energy, and has no pollution to the environment.

[0011] 3、The utility model discloses the preparation work of the concrete maintenance of N section and the concrete maintenance before N+1 section overlaps, and the flow operation of bridge pier construction and concrete maintenance operation carry out simultaneously, do not influence each other and highly coordinate, can improve the efficiency and shorten the construction period.

DETAILED DESCRIPTION

[0016] In order to clearly understand the above -mentioned purpose, feature and advantage of the utility model, below, combining with the drawings and embodiment, the utility model is explained in detail.

[0017] As Figs. 1-3As shown, a template for automatic maintenance of pier concrete, including steel template 5 used for pier construction, high-temperature-resistant water spray hose 7 is arranged on the outer side of the bottom end of the steel template 5, and the number of water spray hoses 7 is reasonably arranged according to the type of pier template (2 for column pier template, 4 for solid pier), the water spray hoses are connected into a whole at the template splicing place, and are connected to the ground water supply system, the water spray hose 7 is provided with one atomizing nozzle 8 every 10° / 20cm, the atomizing nozzle 8 penetrates the steel template 5 through the connecting hole 6 of the steel template, the atomizing nozzle 8 is inclined inward, and the distance between the atomizing nozzle 8 and the concrete surface is not less than 20cm, and the construction personnel opens the valve of the water supply system in time according to the temperature and humidity of the concrete surface to spray and maintain the concrete.

[0018] Working principle, according to the pier construction flow operation, after the concrete 1 of the N section is poured and the mold is removed, the construction personnel connects the water spray hose 7 to the ground water supply system, so that the spraying and maintenance of the concrete can be realized in time, and during the spraying and maintenance of the concrete 1 of the N section, the concrete 2 of the N+1 section can be worked on, such as steel bar binding and concrete pouring, and the two do not affect each other and are highly coordinated, which not only ensures the maintenance quality of the concrete, but also improves the efficiency and shortens the construction period.
