[0002] Most salt chemical companies build salt pans or factories in mining areas. The construction of salt pans only requires the construction of dams, and there is no need to build walls for protection. However, the company's factory buildings, workshops and office areas need to be built with walls to achieve safety separation and aesthetics. Therefore, all corporate office areas in the mining area are separated by walls to achieve safety areas, such as Figure 1 As shown, reinforced concrete 1 is generally used as the foundation of the wall, that is, a certain depth is dug under the ground, the foundation of the wall is made by pre-embedding reinforced concrete 1, and then a steel fence 2 is installed on the upper part of the reinforced concrete or brickwork is directly used to build the wall. The above-mentioned wall foundation treatment method requires a large amount of cement, sand and steel bars. Using reinforced concrete 1 as the foundation on the upper part of the general frozen soil layer and soil layer can make it durable. However, since the mining area is all saline soil, once the saline soil around the reinforced concrete foundation encounters fresh water, the saline soil at the bottom and both sides of the foundation will dissolve, which will eventually cause the bottom of the reinforced concrete 1 to collapse, thereby affecting the stability of the wall and causing the entire wall to tilt, and even in severe cases, there is a risk of the wall collapsing.

[0030] Preferably, in the embodiment of the present invention, the bottom of the steel pipe is cut into a 45-degree bevel angle, and a steel plate (guide plate 10) having the same wall thickness as the steel pipe is welded to the steel pipe.
[0031] Specifically, in the embodiment of the utility model, the diameter of the steel pipe is greater than or equal to 108 mm. In this way, the stability of the steel pipe pile inserted into the saline soil can be increased, thereby increasing the stability of the foundation.
[0032] Among them, the diameter of the steel pipe pile is preferably 200mm-300mm.
[0033] Specifically, in the embodiment of the present invention, the wall thickness of the steel pipe is greater than or equal to 10 mm and less than or equal to 15 mm.

In this way, the contact area between the pile foundation and the saline soil can be increased to better support the support column 20.
[0035] Specifically, in the embodiment of the utility model, the height ratio of the steel pipe pile 11 to the steel cage is greater than or equal to 4 and less than or equal to 6. In this way, the steel pipe pile 11 can be buried deep in the saline soil relative to the concrete foundation 12, thereby increasing the stability of the foundation.
[0036] In the embodiment of the present invention, the height of the steel cage is preferably 500mm-800mm.
[0037] Specifically, in the embodiment of the present invention, the width ratio of the steel cage to the steel pipe pile 11 is greater than or equal to 4, and less than or equal to 6.
[0038] In the embodiment of the present invention, the width of the steel cage is preferably 500mm-800mm.
[0039] Preferably, in an embodiment of the utility model, the steel cage is connected to the steel pipe by welding, and the steel cage includes a plurality of steel layers spaced along the axis of the steel pipe and a plurality of longitudinal bars spaced around the circumference of the steel pipe, each longitudinal bar extending along the axis of the steel pipe, and the plurality of longitudinal bars are used to connect the plurality of steel layers in different planes, and the longitudinal bars are connected to the steel layers by binding, wherein the steel layers include a plurality of annular steel bars located on the outer periphery of the steel pipe and a plurality of transverse bars used to connect the plurality of annular steel bars, the plurality of annular steel bars are spaced along the radial direction of the steel pipe, the plurality of transverse bars are spaced along the circumference of the steel pipe, each transverse bar is arranged at an angle to the axis of the steel pipe, the plurality of transverse bars are welded to the steel pipe, and each transverse bar is connected to the annular steel bars by binding. The above-mentioned steel cage is a cylindrical steel cage, and its specific structure is prior art, which will not be described in detail here.
[0040] Specifically, in an embodiment of the utility model, the fence used in the salt lake area also includes a connecting plate welded to the steel pipe pile 11, the connecting plate is located on the side of the steel pipe pile 11 facing the support column 20, a plurality of bolts are welded on the connecting plate, and the support column 20 is provided with a plurality of threaded holes that cooperate with the threads of the plurality of bolts.
[0041] Through the above arrangement, a detachable connection between the support column 20 and the steel pipe pile 11 can be achieved, which not only allows the steel pipe pile 11 to support the support column 20 , but also facilitates the maintenance or replacement of the support column 20 .
[0042] In one embodiment, the bare steel pipe pile 11 and the support column 20 may also be directly welded.
[0043] Preferably, in the embodiment of the utility model, the connecting plate is welded to the steel pipe pile 11, and the connecting plate is a square steel plate with a side length of 350mm-500mm, and four threaded bolts are welded on the top of the steel plate. The four bolts are in a square manner, and their distribution spacing is generally 200mm-300mm.
[0044] It should be noted that in the embodiment of the present utility model, the specific steps for setting the wall in the salt lake area are:
[0045] 1. First, dig a 50cm square pit in the saline soil with a depth of 50cm. Prefabricate the steel frame on the top of the steel pipe pile and weld the steel bars to form a 40cm-50cm cube frame.
[0046] 2. Use mechanical equipment to drive the steel pipe pile into the saline land. After the steel pipe pile is driven into the saline soil, when the top of the steel frame is at the same level as the original ground, stop driving the steel pipe pile downwards and start pouring concrete on the top steel frame. At this point, the construction of a steel pipe pile is completed. The depth of the steel pipe pile can be set at 2 to 4 meters according to specific needs. Due to the shortage of cement and sand in the salt lake area, after adopting this wall foundation treatment method, the wall on the top of the foundation can use a steel wall instead of a solid brick wall.
[0047] 3. After the concrete solidifies, the support column 20 is installed on the upper part of the concrete, and the support column 20 and the steel pipe pile 11 are connected by multiple bolts on the connecting plate.
[0048] 4. After the support column 20 is fixed, the steel fence and the support column 20 can be connected, and the fence 13 is now installed.
[0049] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: on the one hand, by setting steel pipe piles that pass through the concrete foundation and are inserted into the saline soil, that is, by additionally setting steel pipe piles, not only the strength of the foundation of the fence can be increased, but also the depth of part of the foundation buried in the saline soil can be increased to increase the stability of the foundation of the fence, thereby avoiding the problem of the fence tilting caused by the dissolution of part of the saline soil around the foundation; on the other hand, compared with the prior art that sets the entire continuous concrete foundation, in this embodiment, by setting multiple pile foundations at intervals in the saline soil, that is, using a concrete foundation locally, the amount of concrete used can be reduced to reduce the deadweight of the foundation, thereby reducing the probability of foundation sinking. In this way, the service life of the fence in the salt lake area can be increased, avoiding the problem of high maintenance costs for enterprises due to the need for repairs after a few years.
