[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of the present invention.

[0026] Example 1

[0027] Please see Figure 1 and Figure 2 A pipe rack foundation includes: a foundation 1 and a column 2, with the column 2 located on top of the foundation 1; the foundation 1 and the column 2 are provided with steel reinforcement 3 inside, and anchor bolts 4 are provided on the steel reinforcement 3, with the top of the anchor bolts 4 extending to the outer side of the top of the column 2; the foundation 1 is provided with several sets of first pre-embedded grouting sleeves 6 and second pre-embedded grouting sleeves 7, with the bottom end of the second pre-embedded grouting sleeves 7 extending to the bottom center of the foundation 1; and the column 2 is provided with a hoisting sleeve 5.

[0028] It should be noted that you should refer to [link / reference]. Figure 1 and Figure 2 The hoisting sleeve 5 is arc-shaped and is horizontally set on the column 2; the first pre-embedded grouting sleeve 6 is set vertically, and several groups of the first pre-embedded grouting sleeve 6 are distributed in a rectangular shape on the foundation 1.

[0029] The construction method and specific steps for the pipe rack foundation are as follows:

[0030] First, customize templates for batch construction and level the prefabrication site for the pipe gallery foundation;

[0031] Second, install anchor bolts 4 on the steel keel 3, and install the first pre-embedded grouting sleeve 6 and the second pre-embedded grouting sleeve 7 at the position of the foundation 1 of the steel keel 3. Then, install the lifting sleeve 5 at the column 2 position of the steel keel 3, and fill the inside of the lifting sleeve 5 with fine sand or sawdust (to prevent the lifting sleeve 5 from deforming due to concrete pouring and vibration).

[0032] Third, set up custom templates at 3 locations of the steel reinforcement keel, and then cast the concrete to form the pipe rack foundation;

[0033] Fourth, after the concrete has hardened, remove the formwork and take out the filler (fine sand or sawdust) inside the hoisting sleeve 5.

[0034] Step 5: Apply asphalt to the surface of the pipe rack foundation for corrosion protection.

[0035] A method for installing a pipe rack foundation, the specific steps of which are as follows:

[0036] Step 1: Excavate the foundation pit, set a cushion layer 8 on the base 9 of the foundation pit, and set leveling shims 10 on the cushion layer 8 (e.g., Figure 1 (as shown);

[0037] The second step is to pass the fixing device through the lifting sleeve 5 and hang it on the hook of the lifting device (the lifting device refers to a crane or other lifting equipment). The lifting device will then lift the pipe rack foundation above the leveling shims 10 (e.g., Figure 3 (as shown);

[0038] The third step involves injecting grout into the gap between the bottom of the pipe rack foundation and the pad 8 through the first pre-embedded grouting sleeve 6 and the second pre-embedded grouting sleeve 7 to form a grouting layer. The gap between the bottom of the pipe rack foundation and the pad 8 is then filled (e.g., ...). Figure 1 (as shown);

[0039] The fourth step is to backfill the foundation pit.

[0040] Please see Figure 3 The fixing device includes a pull rope 11 and a balance beam 12. The balance beam 12 is installed on the pull rope 11 (the balance beam 12 and the pull rope 11 are detachably connected, so that the balance beam 12 can be removed from the pull rope 11). The pull rope 11 is provided with two mounting parts 13, and each of the two mounting parts 13 is provided with a limiting part 14. The two limiting parts 14 are respectively inserted into the two ends of the lifting sleeve 5. The mounting parts 13 and the limiting parts 14 are slidably sleeved on the outer wall of the pull rope 11, so that the mounting parts 13 and the limiting parts 14 can slide on the outer wall of the pull rope 11 to change their positions.

[0041] Please refer to Figure 5 The limiting member 14 includes a plug 141, which is installed on the mounting member 13. An expansion member 142 (made of rubber, such as an airbag) is provided on the side wall of the plug 141. An airflow channel 143 is provided inside the plug 141, which is connected to the expansion member 142. An air port is provided on the mounting member 13, which is connected to the airflow channel 143.

[0042] The method of using the fixing device is as follows: one end of the pull rope 11 is passed through the lifting sleeve 5 and connected to the other end of the pull rope 11. The connection points of the two ends of the pull rope 11 are moved above the pipe rack foundation. Then, the balance beam 12 is installed on the pull rope 11 and supported on both sides of the pull rope 11 (the balance beam 12 is above the pipe rack foundation). The connection points of the pull rope 11 are then hooked onto the hook of the lifting device. Then, the installation component 13 is moved and the two limiting components 14 are inserted into the two ends of the lifting sleeve 5 respectively. Air is injected into the airflow channel 143 through the air port. After the expansion component 142 is inflated and contacts the inner wall of the lifting sleeve 5, the air injection is stopped. Then, the pipe rack foundation is lifted using the lifting device.

[0043] It should be noted that a valve is installed at the air inlet to control the opening and closing of the air inlet. During the inflation process, an inflation device, such as an air pump, can be used. When it is necessary to remove the fixing device from the pipe rack foundation, the valve is opened to release the gas inside the expansion member 142, reducing its volume. Then, the pull rope 11 is removed from the hook of the device, the connection at both ends of the pull rope 11 is disconnected, and the balance beam 12 is removed from the pull rope 11. Then, the pull rope 11 is pulled to pull the pull rope 11 out of the hoisting sleeve 5.

[0044] It should also be noted that when the limiting component 14 is inserted into the hoisting sleeve 5, the mounting component 13 contacts the side wall of the pipe rack foundation; the mounting component 13 and the limiting component 14 restrict the pipe rack foundation so that it will not move during the hoisting process, thus ensuring the stability of the pipe rack foundation hoisting.

[0045] In this embodiment, as a further optimization, please refer to... Figure 3 The pull rope 11 is provided with several sets of guide members 15, which are located inside the hoisting sleeve 5. The guide members 15 are spherical, and the pull rope 11 can move easily inside the hoisting sleeve 5 by contacting the inner wall of the hoisting sleeve 5 with the guide members 15.

[0046] In this embodiment, as a further optimization, please refer to... Figure 4The guide component 15 includes a sphere 151. A mounting groove 152 is formed on the outer wall of the sphere 151. A limiting block 154 (made of rubber, which blocks the mounting groove 152 to prevent gas from leaking out of the through hole 153) slides within the mounting groove 152. An elastic element (spring) is installed between the mounting groove 152 and the limiting block 154. A through hole 153 is formed on the sphere 151, communicating with both the mounting groove 152 and the airflow channel 143. When air is injected into the airflow channel 143, some gas will pass through. The through hole 153 enters the installation groove 152, increasing the internal air pressure. This pushes the limiting block 154 to move outward from the installation groove 152, making it contact the inner wall of the lifting sleeve 5. This increases the friction between the guide 15 and the inner wall of the lifting sleeve 5, reducing the probability of the pipe rack foundation moving during the lifting process. When the gas inside the expansion member 142 is discharged, the gas inside the through hole 153 is also discharged, reducing the internal air pressure of the through hole 153. Under the action of the elastic member, the limiting block 154 moves into the installation groove 152 and does not contact the inner wall of the lifting sleeve 5.
