Abstract
The invention relates to a concrete temperature control construction process and a concrete mold-entering temperature rapid regulation and control device which are suitable for controlling the construction temperature of mass concrete and concrete before entering a mold in winter, and can solve the problems of multiple temperature control technical procedures, long flow, high cost, low efficiency and poor applicability of the mass concrete, and greatly improve the construction efficiency and the intelligent degree of concrete pouring.
Description
Technical Field
The invention relates to the field of concrete construction, in particular to a concrete temperature control construction process and a concrete mold-entering temperature rapid regulation and control device, which are particularly suitable for controlling the construction temperature of mass concrete and winter concrete before mold entering.
Background
The concrete pouring process is accompanied with the hydration phenomenon of cement, and the process releases a large amount of heat, so that a large temperature difference occurs in the concrete and on the surface layer, and the generated temperature stress can cause the cracking and the failure of a concrete structure. In prior art, for the construction quality of guaranteeing bulky concrete and reducing the inside and outside difference in temperature of bulky concrete, the technique that adopts contains 3 links: (1) Carrying out cooling treatment on the raw materials of the concrete, wherein the cooling treatment comprises sun shading and sun screening on the sandstone aggregate so as to reduce the temperature of the sandstone aggregate; a plurality of storage bins are arranged on the cementing materials such as cement, so that the cementing materials with higher temperature are fully cooled. (2) Temperature control during stirring and transportation, such as cold water or ice water is adopted in the stirring stage to reduce the machine-out temperature of concrete; and (4) performing heat preservation treatment on the concrete tank truck, such as setting heat preservation cloth and heat preservation cotton to reduce heat exchange between the concrete and the environment in the transportation process. (3) The cold water pipe is pre-buried in the large-volume concrete, the temperature in the concrete is reduced through measures such as cold water circulation or cold air circulation, and a large amount of blankets are laid on the outer surface layer of the large-volume concrete for heat preservation treatment, so that the temperature difference between the inner part and the surface layer of the concrete is reduced.
An intelligent temperature control system and a construction method suitable for large-volume concrete are disclosed in patent 1 (Zhejiang Joe creation and establishment group Co., ltd., china 202111068518.5.2022-01-21), a temperature sensor detects the internal temperature of the large-volume concrete and transmits the internal temperature to a control module, and the control module changes the water supply amount of a water pump to change the cooling rate of a cooling water pipe after data analysis.
A device and a process suitable for cooling large-volume concrete are disclosed in a patent 2 (middle iron construction group, inc.; large-volume concrete cooling device and process: china, 202110232428.9.2021-06-18). Before pouring, a thin-wall steel pipe is pre-embedded, temperature conducting liquid is poured inwards, the top of the thin-wall steel pipe exposed out of the large-volume concrete is connected with a finned tube, and the temperature conducting liquid at the bottom in the thin-wall steel pipe is sealed in a closed cavity formed by the thin-wall steel pipe and the finned tube; the temperature conduction liquid is vaporized to absorb heat and rises into the fin tube when reaching a boiling point after being poured into the mould for heating up due to concrete, then contacts with the ambient temperature in the fin tube to be cooled to be lower than the boiling point, and then the liquid flows back into the thin-wall steel tube, and the circulation is repeated, so that the cooling of the large-volume concrete is realized.
The method in patent 1 needs to waste a large amount of water resources, controls the temperature through the water supply quantity, and has inaccurate temperature control; a large number of thin-wall steel pipes need to be embedded in the cooling device in the patent 2, and temperature conducting liquid exchanges with the external environment in the fin pipes, so that the cooling method is low in efficiency.
The disadvantages of the technology as a whole are: (1) The process is multiple, and involves raw material management, concrete mixing and handling of transportation stage, the laying of cold water pipe before pouring and the setting of insulation material after pouring (like patent 1 and patent 2), and this process consumes a large amount of manpower and materials. (2) The technical cost is high due to more links, and the arranged sunshade and the arranged cementing material storage bin are idle after the construction of mass concrete is completed; the weight of the embedded water pipe is large, and extra labor is generated by arrangement of the embedded water pipe (such as patent 1 and patent 2); the above disadvantages result in a high cost of this technique. (3) For structures with high requirements on seepage resistance, such as certain civil air defense or nuclear power, the water pipes are not allowed to be embedded. At this time, this technique is not practicable (e.g., patent 1 and patent 2). (4) The treatment efficiency is low, for example, the time of concrete transportation and on-site waiting stage is not easy to control, the temperature in the tank car is increased due to the entering of hot air at the tail part of the tank car and the continuous hydration and heat release of cement in the process, and the construction experience proves that although the temperature of the concrete after leaving the tank car can reach about 5 ℃, the temperature of the concrete in the transportation stage can be increased to about 20 ℃. Secondly, the omission of any construction link can cause the failure of the whole technology, for example, the higher temperature of the raw materials can cause the rise of the machine-out temperature and the mold-in temperature of the concrete, and the subsequent work of the cold water pipe can not lead the temperature of the concrete to be in a lower range (for example, patent 1 and patent 2). (5) The concrete temperature is difficult to control accurately, and the long process flow makes the concrete mold-entering temperature difficult to control; secondly, the cooling effect of the cold water pipe is limited, and the result obtained by the equipped temperature monitoring device has hysteresis, so that the real temperature of the concrete is difficult to control (such as patent 1 and patent 2). (6) The prior art has low intelligent degree and has high requirements on the quality of managers and the number of labor workers.
