Description
Technical Field
The invention belongs to the technical field of concrete curing, and particularly relates to a drip irrigation water-saving curing system for concrete.
Background
In house construction and road engineering, for the parts which are difficult to access of municipal pipe networks, a concrete curing mode of combining bucket drip irrigation and geotextile covering is often adopted. The specific method comprises the following steps: firstly, covering geotextile on the surface of concrete, then placing a water bucket with a plurality of small holes penetrating through the bottom on the geotextile, and pouring water into the water bucket. The geotextile wrapping the concrete surface is gradually wetted by water continuously seeping from the small holes at the bottom of the bucket, so that the maintenance water is filled once, sustained release is realized for a long time, evaporation dissipation is reduced, the temperature difference inside and outside the concrete is kept stable, and the maintenance function of temperature shrinkage of the concrete is reduced. The method does not need special personnel to watch for a long time, can effectively improve the maintenance efficiency, saves the maintenance water, and is a green and environment-friendly technical measure.
In the implementation process of concrete curing combining bucket drip irrigation and geotextile covering in the prior art, the difficulty that the covered geotextile gradually evaporates and dries up and cannot play an effective curing role is often faced with untimely bucket water replenishing. Especially when the elevation of the maintenance part is high, such as the top of concrete structures of culverts, retaining walls, water cut-off ditches and the like. The construction of the operators is finished, the operators can not approach the position frequently in daily work, if the manager does not check the water level in the water barrel on a regular basis, the empty water in the water barrel is easy to dry in the maintenance process, and the concrete structure is dry shrinkage phenomenon due to insolation of burning sun, so that the situation of large-scale cracking is caused. Even in some cases, due to the fact that the water bucket is high in position and inconvenient to approach, even if a part of operation or management staff realizes that water in the water bucket is dry, the operation of climbing up and down to finish water supplementing operation is not willing under the condition that other clear instructions are not available; thereby causing the concrete strength at the corresponding position to grow slowly and even causing the quality problem that the strength does not reach the standard. In addition, the water level in the water bucket is continuously reduced in the drip irrigation process, the pressure at the bottom of the water bucket is gradually lowered, so that the outflow speed of water from the holes at the bottom of the water bucket is slower and slower, and when the water in the water bucket is not full, the drip irrigation speed is slower, so that the covered geotechnical cloth is still possibly evaporated gradually and dried, and a better maintenance effect cannot be achieved.
