Description

Technical Field

[0001] This utility model relates to the field of pump house construction technology, specifically an improved structure for a large-volume concrete foundation of a pump house. Background Technology

[0002] In the fire protection system of building structure, the foundation of pump room often adopts the form of large volume concrete structure. According to the "Standard for Construction of Large Volume Concrete" (GB50496-2018), large volume concrete is defined as concrete structure with a minimum size of not less than 1m.

[0003] Because the construction of large-volume concrete requires the preparation of a special construction plan, especially to control its internal and external heat of hydration, pre-embed cooling water pipes to reduce the internal temperature, and pour it in layers continuously to prevent the internal and external temperature difference caused by the heat of hydration from being too large, which could lead to temperature cracks, when the foundation of the pump house is constructed with large-volume concrete, in addition to controlling the heat of hydration and the internal and external temperature difference, temperature monitoring points also need to be installed, which is quite complicated.

[0004] Based on this, this utility model proposes an improved structure for the large-volume concrete foundation of a pump house. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes an improved structure for the large-volume concrete foundation of a pump house, which can optimize the large-volume concrete into a strip foundation structure or a frame foundation structure, perfectly avoiding the cumbersome construction and cracking risks associated with large-volume concrete.

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] This utility model provides an improved structure for a large-volume concrete foundation of a pump house. The technical solution of this utility model is as follows:

[0023] like Figures 1-3As shown, an improved structure for a large-volume concrete foundation of a pump house includes a base plate 3 and a base plate 5. Multiple fixing plates 4 are fixedly connected to the base plate 3. The multiple fixing plates 4 and the base plate 3 form a strip foundation structure 1. The structure also includes:

[0024] Fixed columns 6 are fixedly connected to the base plate 2 5. Multiple horizontal beams 7 are fixedly connected to the multiple fixed columns 6. Multiple vertical beams 8 are fixedly connected between the multiple horizontal beams 7. The base plate 2 5, multiple fixed columns 6, multiple horizontal beams 7 and multiple vertical beams 8 form the frame foundation structure 2. By designing the strip foundation structure 1 or the frame foundation structure 2, the minimum size of all components is strictly controlled to be <1m to avoid the large volume concrete specifications. The entire process from design to acceptance is carried out using ordinary foundation construction, which completely eliminates the special scheme preparation, electronic temperature measurement point installation and complex temperature control measures for large volume concrete, and greatly shortens the construction period.

[0025] Furthermore, such as Figures 1-3 As shown, multiple conduits 9 are provided between multiple fixed plates 4, and multiple seepage holes 10 are provided on the multiple conduits 9. The seepage holes 10 are distributed in a linear array on the conduits 9.

[0026] Furthermore, such as Figures 1-3 As shown, multiple conduits 9 are provided between multiple fixed columns 6. The seepage holes 10 and the conduits 9 work together to drain the seepage water through the conduits 9, so as to prevent groundwater from seeping in and affecting the fixed plate 4 and the fixed column 6.

[0027] Furthermore, such as Figures 1-3 As shown, the fixed plate 4, fixed column 6, horizontal beam 7 and vertical beam 8 are all made of concrete and have internal steel bars. The formwork is erected and the steel bars are tied in a conventional manner, and then the concrete is poured continuously as a whole.

[0028] Furthermore, such as Figures 1-3 As shown, the cross-sectional dimensions of the fixed plate 4 are 500mm wide and 1900mm high. Since the cross-sectional dimensions of the strip foundation structure 1 are less than 1 meter, the construction of large-volume concrete is avoided. It is only necessary to carry out the formwork erection, rebar binding, concrete pouring and curing in accordance with the conventional concrete foundation. In addition, the number of test blocks is reduced, which in particular reduces the risk of concrete cracking in the later stage.

[0029] Furthermore, such as Figures 1-3As shown, the cross-sectional dimensions of the fixed column 6 are 500mm wide and 800mm long, the cross-sectional dimensions of the vertical beam 8 are 500mm wide and 500mm high, and the cross-sectional dimensions of the horizontal beam 7 are 800mm wide and 500mm high. Since the cross-sectional dimensions of the frame foundation structure 2 are less than 1 meter, the construction of large-volume concrete is avoided. It is only necessary to follow the conventional concrete foundation for formwork erection, rebar tying, concrete pouring, and curing. In addition, the number of test blocks is reduced, which in particular reduces the risk of concrete cracking in the later stage.

[0030] The specific working method is as follows: Design strip foundation structure 1 or frame foundation structure 2 according to load requirements, and strictly control the minimum size of all components to be <1m to avoid large-volume concrete specifications. Erect formwork and tie steel bars in a conventional manner, without the need for special temperature control reinforcement. Then, pour concrete continuously as a whole, without the need for layered temperature control and pre-embedding of cooling water pipes. After completion, naturally water-cured for seven days, eliminating the need for a circulating water cooling system. Finally, test blocks are left for acceptance according to conventional standards, without the need for temperature monitoring. This achieves a standard foundation construction process from design to acceptance, completely eliminating the need for special plans, electronic temperature measurement point installation, and complex temperature control measures for large-volume concrete.

[0031] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
