Cast-in-place concrete bent cap maintenance method

Abstract

The invention relates to a cast-in-place concrete bent cap maintenance method. The method includes the steps that a poured cast-in-place concrete bent cap with a formwork removed is coated and coveredwith a wet water retention non-woven fabric; the water retention non-woven fabric is coated with a layer of plastic cloth, and the plastic cloth and the cast-in-place concrete bent cap are bound tightly through a binding rope outside the plastic cloth; a water storage barrel full of water is placed on each of the left side and the right side of the cast-in-place concrete bent cap, a water outletof each water storage barrel is connected with one end of a water dropping hose, and the other end of each water dropping hose is placed in the proper position on the upper portion of the cast-in-place concrete bent cap; and water outflow control valves on the water storage barrels are opened and adjusted to control the water yield, and the bent cap coating water dropping maintenance method is achieved. The maintenance method is convenient and quick to implement, work efficiency is improved, the work intensity of constructors is effectively reduced, a construction period is shortened, engineering cost is saved, meanwhile, the concrete maintenance quality of the cast-in-place concrete bent cap can be improved, and economic benefits and social benefits are good.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a maintenance method for cast-in-place concrete cap beams. Background technique [0002] The traditional cast-in-place concrete cover beam maintenance method is: wrap the cast-in-place concrete cover beam with the formwork removed with non-woven fabric, and then spray the non-woven fabric with water to keep the surface of the non-woven fabric and cast-in-place concrete cover beam moist; The water on the surface of the cloth and cast-in-place concrete cover beams evaporates quickly, and the cast-in-place concrete cover beams covered with non-woven fabrics need to be watered every 1-2 hours to ensure that there is enough water to maintain the cast-in-place concrete cover beams; due to frequent Transportation and maintenance of water, watering and other tasks require a large amount of vehicle shifts and labor, high cost, low efficiency, and poor maintenance effect.
