The specific embodiment
For the benefit of the understanding to structure of the present invention, describes below in conjunction with drawings and Examples.
Shown in Fig. 1, Fig. 1 is the measuring position schematic diagram that concrete floor A point and B are ordered, and Fig. 2 is the flow chart of concrete bottom plate structure maintenance process.
As depicted in figs. 1 and 2, in the first embodiment, the invention provides the maintenance process of a kind of concrete bottom plate structure, comprise the following steps:
S1, two measurement points are set respectively in the surface of a ground concrete floor building, are labeled as respectively: A measurement point and B measurement point,
Regularly measure respectively the Temperature numerical of A measurement point and B measurement point, and the Temperature numerical of the A measurement point measuring and B measurement point is labeled as respectively to T aand T b;
The skin temperature that A measurement point parallels for monitoring the one side that contact with ground with concrete floor, B measurement point is used for monitoring the internal temperature of concrete floor;
Wherein, A measurement point is arranged on any point position on the cross section of the following 0cm to 5cm of upper surface of concrete floor, B measurement point is arranged on any point position on the cross section of upper surface following 20 to 30cm of concrete floor, and this cross section is parallel to the ground.
In the present embodiment, preferably the position of A measurement point and B measurement point is respectively upper surface following 5cm place and the following 25cm of the upper surface place of concrete floor.Select the position at 5cm place and 25cm place under concrete surface to measure herein, because a large amount of actual result is found, the internal-external temperature difference of base plate mainly concentrates in the thickness of surperficial 20cm, so in the present embodiment, preferably in the both ends of the surface in 20cm thickness position 2 5cm places and 25cm place as measurement point.
Respectively the temperature value of measuring at 25cm place under 5cm place and concrete surface under concrete surface is labeled as to T 5cmand T 25cm.
In the present embodiment, preferably each interval time of measurement is five minutes, can to surface temperature of concrete, change and make timely reaction in the shorter time according to this, reaches best maintenance effect.
S2, calculate the temperature gap of described A measurement point and described B measurement point, and calculate the thermograde γ between described A measurement point and described B measurement point by described temperature gap.Thermograde formula: γ=| T a-T b|/| H a-H b| in, H aand H bbe respectively the height value in A measurement point and the short transverse of B measurement point below the upper surface of described concrete floor, in the present embodiment, H aand H bbe respectively 5cm and 25cm;
The T measuring every five minutes 5cmnumerical value and T 25cmnumerical value, calculates T 5cmand T 25cmtemperature difference, finally calculate thermograde γ now:
γ=|T 5cm-T 25cm|/|5cm-25cm|;
S3, monitor the now variation of thermograde, and compare with a preset value, preset value is state's scale value herein, and its thermograde is 15 degrees Celsius/meter.
More now the size of thermograde γ and preset value, when occurring that thermograde γ is greater than in the situation of preset value, is incubated concrete floor, for reducing thermograde numerical value, finally reach the effect that prevents concrete floor cracking.In the present embodiment, the measure of insulation is mainly to add heat-insulation layer, for reducing thermograde.When again occurring that thermograde γ is less than preset value, continue thermograde to observe, reach the effect of real-time monitoring.
When thermograde is greater than preset value, illustrate that hydro-thermal causes the temperature of concrete bottom intralamellar part to continue to be elevated to a warning value, for avoiding concrete floor internal-external temperature difference further to expand, so need to add a cover heat-insulation layer, with this, reduce concrete floor internal-external temperature difference, prevent the concrete floor cracking that the heat of hydration causes.
The heat-insulation layer of adding a cover comprises three layers of upper, middle and lowers, be positioned at this heat-insulation layer intermediate layer be thick geotechnological layer of cloth, what be positioned at this heat-insulation layer levels is thick film, wherein, thick geotechnological layer of cloth comprises several bed thickness geotextiles.

And work as γ, reach maximum γ mAXand while starting to decline, the temperature that 25cm place, concrete floor surface is described is being diminished by the impact of hydro-thermal stress, now 5cm place, concrete floor surface temperature is higher, is prone to the drying regime on concrete floor surface, now concrete floor is sprinkled water and is reached the effect of moisture-keeping maintaining.
Watering amount is determined according to surface temperature of concrete gradient γ, a large amount of experimental datas proves that the injection flow rate of each thermograde γ is different, and show that by experimental result this injection flow rate temperature is directly proportional to Grad, and thermograde γ is larger, and injection flow rate is more.Watering amount parameter corresponding to thermograde now being drawn by experiment determined the moisture-holding capacity of concrete floor.
