A maintenance method and maintenance device for a water-saving bridge pier column

Abstract

The invention belongs to a maintenance method and a maintenance device for a water-saving type bridge pier column. The maintenance method includes the steps of manufacturing a cofferdam, a pier column coating and a water homogenizing ring at the lower end of a to-be-maintained pier column body, preparing before maintaining and maintaining the pier column body. The maintenance device comprises the cofferdam, a water storage tank, the pier column coating, the water homogenizing ring and a water pump. The cofferdam is used for recovering maintenance water in the pier column body and the maintenance water is recycled after being filtered. The water storage tank is used for storing the maintenance water. The pier column coating is used for maintaining the pier column body. The water homogenizing ring is used for making the maintenance water entering into the upper end of the pier column body uniformly enter a water holding layer of the pier column coating at the upper end. The water pump is used for pumping the maintenance water in the water storage tank into the upper end face of the pier column body. The maintenance method and the maintenance device for the water-saving type bridge pier column can realize the maintenance for the water-saving type bridge pier column. The pier column body is uniform in moisturizing and heat dissipation. The maintenance method and the maintenance device for the water-saving type bridge pier column have the advantages of being economical, practical, safe, reliable, capable of saving water, environmentally friendly, less in labor, good in pier column body maintenance quality and strength, high in construction efficiency and good in safety and using effect.

Description

technical field [0001] The invention relates to a maintenance method and a maintenance device for a water-saving bridge pier column. Background technique [0002] With the country's continuous investment in infrastructure, the construction of urban viaducts and rural and mountainous road bridges has continued to develop, and the height of bridges has also continued to increase. The pier column of the bridge plays a supporting role in the bridge, the quality of the pier column plays a very important role in the bridge structure, and the concrete strength is an important index to evaluate the quality of the pier column. The strength of concrete is not only related to raw materials and construction techniques, but also directly related to the maintenance of concrete. After the concrete pouring of the pier column is completed, if the concrete is in a dry environment, the moisture in the concrete will evaporate too quickly, the concrete will be dehydrated, and the surface will a...

Problems solved by technology

Although the water spraying device is superior to artificial watering and moisturizing maintenance, due to the uneven surface of the high bridge pier and pier column, when water is sprayed from top to bottom from the high bridge pier for maintenance, the water is not uniform under the influence of wind and the outside world. The pier column is decent, and the heat in the concrete of the pier column is dissipated too quickly, causing a serious waste of water resources. It is not suitable for construction in mountainous areas with water shortages. After the maintenance period is over, the quality is not ideal, so it is difficult to popularize and use
