[0002] With the continuous expansion of chemical production scale and the increasing size of equipment, the stability and reliability of chemical plant equipment foundations are of paramount importance. Chemical equipment is typically large and heavy, and during operation, it generates various complex loads such as vibration and displacement, which places extremely high demands on the load-bearing capacity and connection stability of the equipment foundations.

[0003] Traditional equipment foundations are prone to a decrease in load-bearing capacity after long-term exposure to heavy pressure and vibration. This not only affects the normal operation of the equipment but may also cause safety hazards. For example, some large reactors have experienced foundation settlement during operation due to insufficient foundation load-bearing capacity, leading to equipment tilting and damage, affecting production and creating safety hazards. Utility Model Content

Detailed Implementation

[0025] To better understand the purpose, structure, and function of this utility model, the following detailed description, in conjunction with the accompanying drawings, provides a structure for strengthening the bearing capacity of a chemical plant equipment foundation, so that those skilled in the art can better understand and implement this utility model. However, the embodiments described are not intended to limit this utility model.

[0026] Example

[0027] Please see Figures 1 to 5As shown in the embodiment of this application, a reinforced structure for the foundation bearing capacity of chemical plant equipment is provided, including a foundation trench 100 and a plurality of foundation piles 200 evenly distributed within the foundation trench 100 and vertically inserted into the bottom of the foundation trench 100. The top of the foundation piles 200 extends upward to the outside of the foundation trench 100. Crushed stone is laid in the foundation trench 100 and a masonry layer 300 is formed by pouring concrete, the height of which is lower than the height of the foundation trench 100. A steel mesh is laid on the masonry layer 300 and a reinforced concrete layer 400 is formed by pouring concrete, the upper surface of which is flush with the upper end of the foundation trench 100. A reinforcing component 500 is fitted on the outer peripheral wall of the foundation piles 200 protruding from the upper surface of the reinforced concrete layer 400, and the bottom of the reinforcing component 500 is fixed to the reinforced concrete layer 400. A connecting flange 230 for fixed connection with chemical equipment is provided at the top of the foundation piles 200.

[0028] Because it is equipped with foundation piles 200, masonry layer 300, reinforced concrete layer 400 and reinforcing components 500, the use of these components together can effectively improve the bearing capacity of the foundation, enhance the overall stability of the foundation, and enable it to withstand heavier chemical equipment, ensuring the stable operation of the equipment. This effectively solves the technical problem that existing chemical equipment foundations, due to insufficient bearing capacity, will settle and cause equipment damage when subjected to heavy equipment loads.

[0029] Specifically, by inserting several foundation piles 200 into the bottom of the foundation trench 100, the foundation can withstand greater loads. For example, when installing heavy equipment such as large reaction vessels, the foundation piles 200 can effectively prevent foundation settlement and ensure the stable installation and operation of the equipment. By laying crushed stone in the foundation trench 100 and pouring a masonry layer 300, a relatively hard and dense bearing layer is formed at the bottom of the foundation, improving the bearing capacity of the foundation bottom. At the same time, it can prevent groundwater or surface water from eroding the foundation soil and prevent changes in the properties of the foundation soil, such as softening or erosion, thereby ensuring the long-term stability of the foundation. By laying a steel mesh on the masonry layer 300 and pouring a reinforced concrete layer 400, the foundation can better resist the vibration, impact and other loads generated during equipment operation. For example, chemical equipment may generate vibrations during startup and shutdown. The reinforced concrete layer effectively suppresses these vibrations, preventing foundation cracks or localized damage. Simultaneously, the reinforced concrete layer evenly distributes the equipment load to the underlying structure (such as the masonry layer 300 and the foundation piles 200), avoiding excessive localized pressure. Furthermore, when laying the reinforcing mesh, it is fixed to the outer perimeter of the foundation piles 200 by welding, further improving the connection stability between the reinforced concrete layer and the foundation piles 200. The reinforcing components 500 are used to strengthen the foundation piles 200 and enhance the connection between them and the reinforced concrete layer, allowing the load borne by the foundation piles 200 to be more effectively transferred to the reinforced concrete layer, thus making the entire foundation structure more compact and stable.

[0030] In a preferred embodiment, the reinforcing component 500 includes two mutually symmetrical semi-annular clamps 510, a connecting component 520, and fasteners 530; the two semi-annular clamps 510 surround the outer peripheral wall of the foundation pile 200 and are fixedly connected by the connecting component 520; the bottom plate 513 of the semi-annular clamps 510 is fixedly connected to the reinforced concrete layer 400 by the fasteners 530.

[0031] Because the reinforcing component 500 is equipped with two semi-annular clamping plates 510, connecting components 520, and fasteners 530, the cooperation between these components not only strengthens the support of the foundation pile 200, making the connection between the reinforced foundation pile 200 and the reinforced concrete layer tighter, but also allows it to clamp foundation piles 200 of different diameters, expanding its applicability. When installing the reinforcing component 500, the two semi-annular clamping plates 510 are placed around the foundation pile 200 from both sides. Then, the connecting components 520 (such as bolts and nuts) are used to lock and fix the two semi-annular clamping plates 510 to the outer peripheral wall of the foundation pile 200. Finally, the fasteners 530 (such as bolts) are used to fix the bottom plate 513 of the two semi-annular clamping plates 510 to the reinforced concrete layer. Installation and disassembly are simple and convenient, requiring no complex construction processes or large installation equipment, effectively saving time and costs.

[0032] In a preferred embodiment, the semi-annular clamp 510 includes a clamp body 511, two connecting plates 512, a bottom plate 513, and several first reinforcing ribs 514; the two connecting plates 512 are respectively connected to the left and right ends of the clamp body 511; the bottom plate 513 is connected to the lower end of the clamp body 511 and is connected to the bottom of the connecting plates 512; the first reinforcing ribs 514 are fixed on the bottom plate 513 and connected to the outer side wall of the clamp body 511, and the several first reinforcing ribs 514 are evenly spaced apart.

[0033] Because the semi-annular clamping plate 510 is provided with a clamping plate body 511, two connecting plates 512, a bottom plate 513, and several first reinforcing ribs 514, the cooperation of these components strengthens the support for the foundation pile 200 and improves the foundation bearing capacity. Specifically, by setting two connecting plates 512 to the left and right ends of the clamping plate body 511 respectively, the clamping plate body 511 can form a closed annular structure when enclosing the foundation pile 200, greatly increasing the overall strength of the clamping plate body 511. By setting several first reinforcing ribs 514 fixed to the bottom plate 513 and connected to the outer wall of the clamping plate body 511, multiple triangular stable structures are formed, which can effectively enhance the connection strength between the clamping plate body 511 and the bottom plate 513. When the clamping plate is subjected to pressure from the foundation pile 200, the first reinforcing ribs 514 can disperse the pressure and avoid stress concentration at the connection between the clamping plate body 511 and the bottom plate 513.

[0034] In a preferred embodiment, a reinforcing cage 210 is installed inside the pile 200. The reinforcing cage 210 enhances the overall shear and tensile strength of the pile 200, thereby strengthening the foundation structure. Specifically, the pile 200 is a hollow structure with an open top, allowing the reinforcing cage 210 to be hoisted into the pile during construction. After the reinforcing cage 210 is fixed inside the pile 200, concrete can be poured into the pile 200 to integrate it with the reinforcing cage 210, thus strengthening the overall shear and tensile strength of the pile 200. Furthermore, the bottom of the pile 200 is cone-shaped, facilitating its vertical insertion into the bottom of the trench 100 during construction using static pressure or hammering.

[0035] In a preferred embodiment, a plurality of evenly distributed permeation holes 220 are provided on the side wall of one end of the foundation pile 200 inserted into the bottom of the foundation trench 100. By providing permeation holes 220, cement grout can permeate into the soil through the permeation holes 220 when concrete is poured into the foundation pile 200, so as to form a barb-like structure 600 on the outer side wall of the foundation pile 200, thereby enhancing the connection strength between the foundation pile 200 and the soil and further improving the overall stability of the foundation. Specifically, the number of permeation holes 220 can be ten, twenty, thirty, or forty, etc. The specific number of permeation holes 220 can be adapted according to actual needs. No limitation is placed on the specific number of permeation holes 220 here. In this embodiment, sixteen permeation holes 220 are provided, and these sixteen permeation holes 220 are evenly divided into four groups. The four groups of permeation holes 220 are evenly spaced along the circumference of the pile 200, and four permeation holes 220 in each group are evenly spaced along the length of the pile 200, so that barbed structures 600 can be formed at different locations on the outer periphery of the pile 200 after the cement grout has solidified. Furthermore, if groundwater enters the pile 200 through the permeation holes 220 before pouring concrete into the pile 200, a water pump can be installed at the top of the pile 200, and a pumping pipe can be extended into the pile 200 to remove the groundwater. In addition, during the process of pouring concrete into the foundation pile 200, cement grout is pressed from the permeation hole 220 into the soil outside the foundation pile 200 using a pressurized method.

[0036] In a preferred embodiment, a plurality of second reinforcing ribs 231 are fixedly connected to the bottom of the connecting flange 230, and the plurality of second reinforcing ribs 231 are equally spaced apart from each other; the end of the second reinforcing rib 231 away from the connecting flange 230 extends obliquely downward toward the pile 200 and connects to the outer side wall of the pile 200. Due to the presence of the second reinforcing ribs 231, the connection strength between the connecting flange 230 and the pile 200 can be effectively improved, the stress generated when the equipment load is transferred to the pile 200 can be distributed, and deformation or damage to the connection part due to stress concentration can be avoided, further improving the bearing capacity and stability of the entire foundation structure.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
