A multi-functional concrete pier health-preserving cloth and laying device

Abstract

The invention relates to the field of bridge engineering, and particularly relates to an energy-saving concrete bridge pier curing equipment. The equipment includes a pier, and is characterized by further comprising curing cloth, a control system, a water storage tank, a fan heater, a laying device and a wind speed testing device; the air humidity and the air temperature around the pier can be maintained automatically to ensure the quality of curing of the pier, and the equipment also has functions of sunshading and wind blocking.

Description

Technical field: [0001] The invention relates to the field of bridge engineering, in particular to a multifunctional concrete pier health-preserving cloth and a laying device. Background technique: [0002] As we all know, the concrete bridge piers that have just been poured need to be carefully maintained, which is an important means to improve the early and final mechanical properties of concrete and ensure the impermeability and durability of concrete. When the maintenance is not in place, the surface quality of the concrete surface is prone to decrease. The main reason is that when the ambient humidity is lower than the internal humidity of the concrete, the moisture evaporation channels and pores left in the concrete will cause the surface to become loose; the maintenance duration is poor, and the concrete surface alternates between wet and dry , when the strength of concrete is low, it is subject to repeated changes in temperature and humidity, forming surface shrinkag...

Problems solved by technology

When the maintenance is not in place, the surface quality of the concrete surface is prone to decrease. The main reason is that when the ambient humidity is lower than the internal humidity of the concrete, the moisture evaporation channels and pores left in the concrete will cause the surface to become loose; the maintenance duration is poor, and the concrete surface alternates between wet and dry , when the strength of concrete is low, it is subject to repeated changes in temperature and humidity, forming surface shrinkage and temperature cracks; during the strength growth period, the concrete surface is most affected by external influences, resulting in permanent loss of concrete strength within a certain range of the surface. Using the direct watering maintenance method requires long-term retention of scaffolding or turn-back ramps, which takes up a lot of construction equipment, resulting in a low turnover utilization rate of construction equipment; maintenance personnel need to climb to the top of the pier several times a day to sprinkle water on the pier body and pier top Maintenance requires a lot of work; directly spray the pier body and the pier top tray with water. Under the action of sunlight, high temperature and wind, the water evaporates quickly. To ensure the quality of maintenance, watering and maintenance must be repeated several times a day; Spraying is carried out on the pier for maintenance, but the spraying rebound rate is high; the high pier uses a submersible pump to send water to the top of the pier, and the spraying is affected by the tray on the top of the pier, so the water cannot be sprayed on the pier, resulting in partial energy consumption and water resources. waste; watering conservation method
