Technical Field
[0001] The utility model relates to the technical field of concrete structures, in particular to a crack prevention structure for the concrete of a raw material pool. Background Art
[0002] The concrete raw material pool for chemical industry is a concrete pool specially used in the chemical industry. Its design and material selection need to consider the storage characteristics of chemicals and the chemical corrosion resistance of concrete. Therefore, the concrete raw material pool for chemical industry needs to have higher chemical erosion resistance and structural stability. Ordinary concrete may not be able to withstand long-term contact, so special concrete with chemical corrosion resistance needs to be used, such as adding anti-corrosion admixtures or using special types of cement. Sometimes high temperatures or drastic temperature changes are involved in chemical production, and the materials of the concrete raw material pool need to have good resistance to thermal expansion and contraction to avoid cracking caused by temperature changes. Vibration, mechanical shock, etc. may occur in chemical production, and the concrete of the raw material pool must have sufficient strength and durability to ensure its long-term use under harsh conditions.
[0003] For this reason, the concrete raw material pool needs to use special concrete with relatively high quality. In order to make the concrete raw material pool have good crack prevention performance, the raw material pool needs to have a relatively large thickness. However, the prices of these special concretes are usually relatively high, which undoubtedly increases the construction cost. And if the thickness is small, it does not have good crack prevention performance. Summary of the Utility Model
[0004] To solve the contradiction between crack prevention and cost of the raw material pool, the utility model proposes a crack prevention structure for the concrete of the raw material pool, which can save the use of raw materials while ensuring the crack prevention performance of the raw material pool.
[0005] The technical solution adopted by the utility model is to design a crack prevention structure for the concrete of the raw material pool, including a concrete main body. The concrete main body includes an inner pool wall, and an outer pool wall is sleeved outside the inner pool wall. The inside of the inner pool wall is used for storing raw material liquid, and the space between the outer pool wall and the inner pool wall is a liquid filling cavity, and a balance liquid is filled in the liquid filling cavity.
[0006] In some embodiments, the liquid filling cavity is communicated with a liquid supply device, and the liquid supply device controls the liquid volume of the balance liquid in the liquid filling cavity.
[0007] In some embodiments, the liquid filling cavity is communicated with a plurality of liquid storage devices through a pumping device, and different liquid storage devices store solutions with different densities.
[0008] In some embodiments, the bottom of the inner pool wall has a pool bottom that arches upward.
[0009] In some embodiments, a sealing cover is arranged at the upper port of the liquid filling cavity, and a breathing valve is arranged on the sealing cover.
[0010] In some embodiments, both the outer pool wall and the inner pool wall are circular.
[0011] In some embodiments, the outer pool wall is circular and the inner pool wall is rectangular.
[0012] In some embodiments, it further includes a pipeline that passes through the liquid filling cavity to connect the inner side of the inner pool wall and the outer side of the outer pool wall.
[0013] In some embodiments, the outer pool wall is made of metal.
[0014] In some embodiments, the material of the inner pool wall is anticorrosive concrete, and the material of the outer pool wall is waterproof concrete.
[0015] Compared with the prior art, the present utility model has the following beneficial effects:
[0016] Due to the use of the pressure balance of the liquid on the inner pool wall in the present utility model, the inner pool wall does not need to be made too thick, thereby saving the use of special concrete raw materials. In addition, since there is liquid between the outer pool wall and the inner pool wall, and the liquid has good shock absorption, the raw material pool can resist external or internal vibrations, making the anti-cracking performance better.

[0022] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model will be further described in conjunction with the accompanying drawings. However, the present utility model is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, all combinations of the features described in the embodiments are not necessarily required for the solution of the utility model.
[0023] The principle and structure of the present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments. Embodiment
[0024] As Figure 1 、 2 、shown in Fig. 3, the anti-cracking structure of the raw material pool concrete includes a concrete main body. The concrete main body includes an inner pool wall 1, and an outer pool wall 2 is sleeved outside the inner pool wall 1. The inside of the inner pool wall 1 is used to store the raw material liquid 3. The space between the outer pool wall 2 and the inner pool wall 1 is a liquid filling cavity, and a balance liquid 4 is filled in the liquid filling cavity. The balance liquid 4 is, for example, water or other liquids. The pressure of the liquid on the inner pool wall 1 is used to balance the pressure of the raw material liquid 3 on the inner side of the inner pool wall 1, so that the inner pool wall 1 is in force balance and avoids cracking. Since the outer pool wall 2 does not contact the raw material liquid 3 and is only used to store ordinary liquids such as water, ordinary cement or other materials with higher strength can be used, for example, it can be a metal material. And due to the balance of the pressure of the liquid on the inner pool wall 1, the inner pool wall 1 does not need to be made too thick, thus saving the use of special concrete raw materials. The material of the inner pool wall 1 is anti-corrosion concrete, and the material of the outer pool wall 2 is waterproof concrete. In addition, since there is a liquid between the outer pool wall 2 and the inner pool wall 1, and the liquid has a good shock-absorbing effect, the raw material pool can resist external or internal vibrations, making the anti-cracking performance better.
[0025] The liquid filling cavity is communicated with a liquid supply device, and the liquid supply device controls the liquid volume of the balance liquid 4 in the liquid filling cavity. The liquid supply device is, for example, a water pump 5, so as to control the liquid volume of the balance liquid 4 through the water pump 5 according to the amount of the raw material liquid 3, so as to keep the inner pool wall 1 in force balance.
[0026] The liquid filling cavity can be communicated with multiple liquid storage devices through a pumping device. For example, it is communicated with multiple liquid storage tanks through multiple water pumps 5. Different liquid storage devices store different densities, so as to adjust the density of the balance liquid 4 according to the density of the raw material liquid 3, so as to achieve a better balance effect.
[0027] The bottom of the inner pool wall 1 has a pool bottom 6 that arches upward, so as to provide the compressive strength at the bottom.
[0028] A sealing cover 7 is provided at the upper port of the liquid filling chamber. A breathing valve 8 is provided on the sealing cover 7 to prevent external impurities from entering. The breathing valve 8 is a valve that communicates with the outside air pressure, so that the internal air pressure is the same as the outside air pressure.
[0029] In this embodiment, both the outer pool wall 2 and the inner pool wall 1 are circular. Of course, it is also possible that the outer pool wall 2 is circular and the inner pool wall 1 is rectangular, which is beneficial to improving the strength of the rectangular pool.
[0030] It further includes a pipeline 9 passing through the liquid filling chamber to communicate the inner side of the inner pool wall 1 and the outer side of the outer pool wall 2, so as to facilitate the discharge of the raw material liquid 3 from the bottom.
[0031] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
