Description
Technical field
The present invention relates to building machinery technical field, in particular to a kind of pier shaft concrete sprinkling curing system and
Concrete sprays maintenance process.
Background technology
In the prior art, construction site generally connects electricity and send for the maintenance of concrete by artificial watering (water supply) or manually
Water operates spray pipeline to complete, and such maintenance method has the following aspects：
1. artificial watering is lack of standardization.To keep concrete, holding surface moistens in the standard curing period after pouring, and fills
Dispersion removes the heat of hydration, and general watering early period is more frequent, and the later stage watering frequency is reduced, and live artificial watering is difficult to accomplish to spill on time
Water often misses the watering time, reduces watering number, especially at night.
2. the grasp of pair temperature, humidity is inaccurate.It is needed according to maintenance regulatory requirements to conserving works surface environment temperature
The monitoring (large volume coagulation also needs monitoring internal temperature) that degree, humidity are timed, to differentiate its moistening degree and environment temperature
It takes measures to be conserved, and scene is lack of standardization to the monitoring of temperature, is not monitored substantially to humidity, it is difficult to according to epidemic disaster
Situation accomplishes to conserve in due course.
3. it is insufficient or excessive to conserve water consumption.How much watering depends on beam body volume and surface area, very few (the moistening journey of watering
Degree not enough or cannot penetrate into inside) then maintenance effect it is bad, at most water resource waste of sprinkling water, and excessive watering often results in
Concrete early stage surface strength it is relatively low to generate fade, the mass defects such as washmarking.
4. it is low to conserve efficiency.Nourishment needs special messenger to complete, and Liang Chang more than general 12 pedestals just needs 1~2
The special maintenance worker of name, the maintenance worker that production peak period needs is more, thus maintenance cost is higher, conserves inefficiency.
5. the maintenance of mass concrete, which is typically necessary, takes surveillance and control measure, manual testing's temperature and humidity, analysis are sentenced
It is disconnected whether to carry out private water supply cooling and surface watering moisturizing.Slightly improper (worker conserves not in time) concrete will be burnt out
(internal and external temperature is excessive to cause thermal stress cracks to generate).

Pier body 6；Since spray assemblies 5 include pier top spray piping 10 and multiple nozzles 11, pier top spray piping 10 is annularly installed
On pier body 6, water-supply-pipe 9 is connect with pier top spray piping 10, and multiple nozzles 11 are mounted on pier top spray piping evenly and at intervals
On 10, therefore, when starting high-lift pump 8, the water in water storage box 7 can be transported to each position by water-supply-pipe 9
In the spray piping at place, and then comprehensive spray being carried out to pier body 6 and is conserved so that the service life is longer for 6 concrete of pier body,
Improve the maintenance quality of 6 concrete of pier body.Simultaneously as the time relay 3 is electrically connected with spray assemblies 5, the time relay 3
Being turned on and off for spray assemblies 5 can be controlled；Therefore, the reservoir storage of water storage box 7 can ensure after continuously spraying operating condition,
The time interval of setting time relay 3 and duration simultaneously start spray system power supply, and spray system will enter work at this time
Make state；After relay reaches specified spray time, the switch of high-lift pump 8 is connected, high-lift pump 8 is from water storage box
It draws water and is sent to water-supply-pipe 9 in 7, water-supply-pipe 9 connects pier top spray piping 10 and pier shaft spray piping 12, spray piping and pier shaft
The geotextiles 13 that spray piping 12 wraps up pier top carry out spray watering, by the geotextiles 13 of moistening through flow by gravity by water curtain
It is uniformly transmitted on the pier shaft concrete surface that need to be conserved, after water spraying time reaches the scheduled time, the time relay 3 closes water
Switch pump stops water spray；Therefore, which may be implemented concrete curing process engineering, rule
Generalized and automation, reducing human factor influences, and improves concrete curing quality, extends concrete service life.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this field
