Background

The temperature of concrete, especially mass concrete, is required to be strictly controlled in the construction process, and the internal temperature of the concrete is controlled within a design allowable range. Because of the large heat of hydration of cement, the early temperature control of mass concrete is essentially a cooling process, i.e. cooling of the concrete. The cooling of bulky concrete generally adopts the mode of laying the condenser pipe inside the concrete, through letting in circulating flow's cold water in order to reduce the inside temperature of concrete to the condenser pipe, and current condenser pipe laying mode includes that the rectangle arranges and the quincunx type arranges two kinds, and the condenser pipe then adopts the running water steel pipe more.

For this reason, it is generally necessary to build large basins to provide the cold water needed for circulation. However, in some construction sites, there is sometimes no space for building a large water pool, especially when building a dry bridge or an independent foundation in a deep mountain, not only is it difficult to build the water pool, but also construction water is difficult to find, and many times, drinking water lacks hundreds of cubic meters of construction water needed for cooling concrete.

Detailed Description

The invention is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in fig. 1, fig. 2 and fig. 3, a large-volume concrete condensing system includes a cooling water pipe structure 2 formed by arranging steel pipes and a circulating water supply structure, wherein the cooling water pipe structure 2 in the present scheme may be arranged in a rectangular shape or a quincunx shape, and is the same as the cooling water pipe structure 2 in the prior art. The cooling water pipe structure 2 is used for being embedded and installed in the mass concrete 1 to form a cooling channel. The circulating water supply structure comprises a water temperature monitor, a rack, a copper pipe 6 processed by pure copper, a copper plate 7 processed by pure copper, a water pump 10, a water supplementing tank 8, an exhaust fan 12, an electric control console 4, a water inlet pipeline 11 and a water outlet pipeline 3. Copper pipe 6 is circuitous and fixed the laminating from top to bottom on copper 7, and copper pipe 6 becomes snakelike arranging promptly, and copper 7, automatically controlled platform 4, water pump 10 and the equal fixed mounting of moisturizing case 8 are in the frame.

One end of the water inlet pipeline 11 is fixedly communicated with a water inlet of the cooling water pipe structure 2, and the other end of the water inlet pipeline 11 is fixedly communicated with the copper pipe 6; one end of the water outlet pipeline 3 is fixedly communicated with a water outlet of the cooling water pipe structure 2, and the other end of the water outlet pipeline 3 is fixedly communicated with a water replenishing tank 8; the water inlet of the water pump 10 is communicated with the water replenishing tank 8, the water outlet of the water pump 10 is communicated with the copper pipe 6, and a water circulation system is formed by the cooling water pipe structure 2, the water pump 10, the water replenishing tank 8, the water inlet pipeline 11, the water outlet pipeline 3 and the copper pipe 6. An externally-purchased water temperature monitor (not shown in the figure) is installed in the water replenishing tank 8, and the water temperature in the water replenishing tank 8 is monitored by the water temperature monitor. As the key improvement of the invention, the cross-sectional area of the copper pipe 6 in the scheme is larger than that of the steel pipe used by the cooling water pipe structure 2, the length of the copper pipe 6 is larger than the total length of the steel pipe used by the cooling water pipe structure 2, and particularly, the length of the copper pipe 6 in the optimized embodiment is 1.5 times of that of the steel pipe. The electric console 4 is respectively electrically connected with the water pump 10 and the water temperature monitor, and the detection data of the water temperature monitor is fed back to the electric console 4, and the electric console 4 controls the working state of the water pump 10.

In the preferred embodiment, as shown in fig. 1, the through holes 5 are formed on the surface of the copper plate 7, and the through holes 5 are distributed in a matrix along the surface of the copper plate 7. As shown in fig. 2, the exhaust fan 12 is fixedly installed on the copper plate 7, the exhaust fan 12 is located on the other side plate surface opposite to the copper tube 6, and the air outlet of the exhaust fan 12 faces a direction away from the copper tube 6. The exhaust fan 12 is also electrically connected to the console 4. When the exhaust fan 12 is working, the air flow direction is from the copper pipe 6 to the exhaust fan 12, that is, the hot air is sucked by the exhaust fan 12 instead of being blown, which is an important setting of the present invention.

In order to further improve the using effect of the invention, as shown in fig. 1 and 3, a cooler 9 is additionally arranged between the copper pipe 6 and the water replenishing tank 8, and the cooler 9 is positioned between the copper pipe 6 and the water replenishing tank 8. The cooler 9 includes a hollow casing 92, threaded joints 91 communicated with the hollow cavity are provided at both ends of the casing 92, and a water wheel 13 is rotatably connected in the hollow cavity of the casing 92. When in use, the threaded joint 91 at the upper end of the shell 92 is fixedly communicated with the copper pipe 6, and the threaded joint 91 at the lower end of the shell 92 faces the water replenishing tank 8.

The principles of the present invention are described in a specific manner of use below: in the present invention, the fixed communication of the water pump 10, the water replenishing tank 8, the copper pipe 6, and the like, all refer to closed fixed communication, and for example, when the communication between the pipelines in the prior art is performed, a raw tape needs to be wound at the interface to prevent the gas or liquid from falling off from the joint, which is a common technique in the prior art. The water replenishing tank 8 in the present case may be a non-sealed common tank with an opening, or a sealed tank with a sealed top cover, and the implementation of the present invention is not affected no matter whether the water replenishing tank 8 is sealed or not, which will be described in detail herein. Meanwhile, the copper pipes 6 and the copper plates 7 in the cold collar system of the invention are not used for reducing the temperature of hot water to a very low temperature, but only in a water circulation mode, the water temperature in the water supplementing tank 8 is ensured to be always lower than the temperature of the hot water flowing through the mass concrete 1, the temperature difference is about 15 degrees under a general condition, and the construction requirement of reducing the temperature of the mass concrete 1 is met.

In specific use, the circulating water needs to be injected into the water replenishing tank 8, the injected water amount can be 1.2 to 1.5 times of the water amount required for completing one cycle through a steel pipe, a copper pipe 6, a connecting pipeline and the like used by the cooling water pipe structure 2, and the capacity is basically equal to the water capacity of the water replenishing tank 8. Of course, for the large water pool used in the prior art, the water amount used by the condensing system is almost several percent of the water amount used by the existing cooling system under the same condition. After the water pump 10 is started, the water pump 10 pumps cold water in the water replenishing tank 8 and conveys the cold water to the cooling water pipe structure 2 through the water inlet pipeline 11, and the cooling of the mass concrete 1 is realized through the cooling water pipe structure 2. Cold water is heated into hot water after absorbing heat through the cooling water pipe structure 2, the hot water flows into the copper pipe 6 through the water outlet pipeline 3, the hot water in the copper pipe 6 is cooled through the copper pipe 6 and then flows into the water supplementing tank 8, and therefore a circulation process is completed.

Although copper and steel are both metals, the heat conduction coefficient of pure copper is much larger than that of steel, the heat conduction coefficient of pure copper is 389-401W/mK, and the heat conduction coefficient of iron or steel is about 80W/mK. In the invention, the cross-sectional area and the total length of the copper pipe 6 are larger than those of the steel pipe used by the cooling water pipe structure 2, so that the arrangement can ensure that cold water absorbs heat in the large-volume concrete 1 and can be completely dissipated by the copper pipe 6. In the scheme, the copper pipe 6 is vertically circuitous and attached to the copper plate 7, and the arrangement is necessary, because the air heat conduction coefficient is low, and after the copper pipe 6 is contacted with the copper plate 7, the copper plate 7 further increases the heat dissipation area of the copper pipe 6, so that the hot water is cooled to be cold water after passing through the copper pipe 6 and returning to the water supplementing tank 8. The water has certain volatility after being heated, but in the scheme, the defect can be compensated by adding water into the water replenishing tank 8, the amount of the volatilized water is very small, and the water can be replenished once a day generally.

In order to further increase the heat dissipation effect of the copper pipe 6 and the copper plate 7 and aim at the weather with higher temperature, an exhaust fan 12 is additionally arranged on the copper plate 7, and a cooler 9 is additionally arranged between the water pump 10 and the water replenishing tank 8. Exhaust fan 12 passes through-hole 5 on the copper 7, and through-hole 5 is not sheltered from by copper pipe 6, extracts the radiating heat of copper pipe 6, can show the heat dissipation that improves copper pipe 6. The exhaust fan 12 is fixed on the other side opposite to the copper tube 6, so as to further avoid the influence of part of the hot air exhausted by the exhaust fan 12 on the heat dissipation of the copper tube 6, and ensure the heat dissipation efficiency of the copper tube 6. According to the cooler 9, when water flows through the cooler 9, the water flow impacts the water wheels 13 in the shell 92 of the cooler 9, and the impacted water wheels 13 disperse the water flow, so that the heat of the water flow can be further dissipated, and the water temperature is favorably reduced.

The invention has the beneficial effects that: the invention adopts the cooling water pipe structure 2 which is arranged by steel pipes in the prior art to cool the mass concrete 1, and utilizes the heat conductivity coefficient difference of copper metal and steel metal, namely, the copper pipe 6 and the copper plate 7 which are made of pure copper cool the hot water, thereby achieving the purpose that the temperature of the water which flows back to the water supplementing tank 8 is lower than the temperature of the water in the cooling water pipe structure 2, realizing the synchronous circulation of the water in the water supplementing tank 8, finally achieving the purpose that when the mass concrete 1 is cooled by adopting a water cooling mode, a large water pool is not required to be built, and the water consumption is saved, having positive significance for the cooling construction of the mass concrete 1 in areas lacking sites and water shortage areas in reality, and greatly reducing the construction difficulty. An exhaust fan 12 is additionally arranged on the copper plate 7, and a cooler 9 is additionally arranged between the water pump 10 and the water replenishing tank 8. Exhaust fan 12 passes through-hole 5 on copper 7, extracts the radiating heat of copper pipe 6, and the radiating effect of improvement copper pipe 6 that can show through increasing desuperheater 9, rivers will be to the heat that can further give off rivers of such setting up of desuperheater 9 casing 92, help reducing the temperature fast.

The present invention is not limited to the above-described preferred embodiments, but includes all modifications, equivalents, and improvements within the spirit and scope of the present invention.
