Description

Technical Field

[0001] The invention belongs to the technical field of industrial and civil building pile foundation engineering construction, and in particular relates to a method for aligning and positioning multi-section concrete prefabricated pile connections. Background Art

[0002] In the existing field of industrial and civil construction pile foundation engineering construction technology, it is often encountered that the pile sinking depth is deep and multiple prefabricated piles need to be connected. The problem of poor weld quality caused by the misalignment between the piles often occurs. In addition, the construction period is long if the prefabricated piles are leveled and aligned only by their own weight or by pulling with wire ropes. Therefore, the pile head alignment problem is one of the important issues in the pile connection process. In the traditional pile connection alignment, the pile head is moved by wire rope through a winch, and then the operator uses a crowbar to adjust the pile head left and right. In this way, it is impossible to accurately align and position the piles during alignment. It is not easy to control the distance of the pile head during alignment. The alignment time is long, and even the welding of piles is started before they are completely aligned and there is still misalignment. The existence of the above problems often causes the longitudinal axes of the two piles to be not on the same straight line after the pile connection, and the quality of the welding cannot be guaranteed. There are quality risks. In serious cases, there is a risk of safety and quality accidents when the construction is adversely affected. Summary of the invention

[0015] Furthermore, the upper alignment sleeve and the lower alignment sleeve are equidistant from one side of the precast pile.

[0016] Furthermore, the pin penetrates and is connected to the interior of the upper alignment sleeve and the interior of the lower alignment sleeve.

[0031] The present invention will be further described below in conjunction with embodiments and drawings:

[0032] In one embodiment of the present invention, Figure 1-2 As shown, a device for controlling the alignment and positioning of a multi-section precast concrete pile connection includes: a long lever arm 1, a short lever arm 2, an inner thread sleeve 3, an upper alignment sleeve 4, a lower alignment sleeve 5 and a pin 6. The inner thread sleeve 3 is welded on one side of the long lever arm 1, and the short lever arm 2 is connected to the long lever arm 1 through the inner thread sleeve 3.

[0033] The upper alignment sleeve 4 is connected to the side of the head of the upper precast pile, and the lower alignment sleeve 5 is connected to the side of the head of the lower precast pile; the pin 6 cooperates with the upper alignment sleeve 4 and the lower alignment sleeve 5 to fix the positions of the upper precast pile 7 and the lower precast pile 7, thereby achieving the effect of precise positioning.

[0034] like Figure 1-2As shown, the long lever arm 1 is a carbon steel round tube. In this embodiment, an inner thread sleeve 3 is welded on one side of the long lever arm 1 near the middle, wherein the inner thread sleeve 3 is arranged in pairs. In this embodiment, two groups are arranged, a total of three pairs of inner thread sleeves 3, which can simultaneously meet the needs of aligning and positioning concrete precast piles 7 of various pile diameters. As an alternative. The number of inner thread sleeves 3 can be increased to adapt to concrete precast piles 7 of different pile diameters in a wider range. The short lever arm 2 is threadedly connected to the inner thread sleeve 3 and connected to the long lever arm 1 through the inner thread sleeve 3; wherein the short lever arm 2 is arranged in pairs, and the inner thread sleeve 3 at the required position is determined according to the cross-sectional width of the precast pile. The short lever arm 2 is threadedly connected to the inner thread sleeve 3 to limit the position of the upper section of the precast pile 7 required for the pile connection, so that it is just stuck on both sides of the precast pile 7.

[0035] like Figure 2 As shown, the upper alignment sleeve 4 is spot welded on the side of the head of the upper precast pile 7, and the lower alignment sleeve 5 is spot welded on the side of the head of the lower precast pile 7. The distance between the upper alignment sleeve 4 and the end of the upper precast pile 7 is equal to the distance between the lower alignment sleeve 5 and the end of the lower precast pile 7. The distance between the upper alignment sleeve 4 and the lower alignment sleeve 5 and one side of the precast pile 7 is equal, which can realize standardized and mass construction.

[0036] Figure 2 The inner diameters of the upper alignment sleeve 4 and the lower alignment sleeve 5 shown in the figure match the diameters of the pin 6, and the pin 6 penetrates and is connected to the interior of the upper alignment sleeve 4 and the interior of the lower alignment sleeve 5. At the same time, the bottom of the lower alignment sleeve 5 is closed, so that the pin 6 is just clamped with the interior of the lower alignment sleeve 5 to prevent the pin 6 from falling. By cooperating with the pin 6, the upper alignment sleeve 4 and the lower alignment sleeve 5, a good positioning effect is achieved, and the connection between the upper prefabricated pile 7 and the lower prefabricated pile 7 is achieved, so that the upper prefabricated pile 7 and the lower prefabricated pile 7 will not produce longitudinal displacement, and can only be rotated by the pin 6. The alignment and connection between the upper prefabricated pile 7 and the lower prefabricated pile 7 can be completed by rotation, and the longitudinal axes of the two prefabricated piles 7 after the connection are in the same straight line.

[0037] The working process of an embodiment of the present invention:

[0038] S1: spot weld the upper aligning sleeve 4 to the side of the head of the upper precast pile, and spot weld the lower aligning sleeve 5 to the side of the head of the lower precast pile, ensuring that the distance between the upper aligning sleeve 4 and the end of the upper precast pile 7 and the distance between the lower aligning sleeve 5 and the end of the lower precast pile 7 are equal; the distance between the upper aligning sleeve 4 and the lower aligning sleeve 5 and one side of the precast pile 7 are equal;

[0039] S2: Determine the spacing between the short lever arms 2 arranged in pairs according to the cross-sectional width of the prefabricated piles 7 to be constructed, and connect the short lever arms 2 to the inner thread sleeves 3 of the corresponding spacing;

[0040] S3: moving the long lever arm 1 to clamp the short lever arm 2 arranged in pairs on both sides of the upper precast pile to be aligned;

[0041] S4: Rotate the long lever arm 1 so that the upper aligning sleeve 4 and the lower aligning sleeve 5 are coaxial, and then insert the pin 6 into the upper aligning sleeve 4 and the lower aligning sleeve 5;

[0042] S5: Using the pin 6 as the rotation axis, continue to rotate the long lever arm 1 in a clockwise or counterclockwise direction until the pile edges and pile angles of the upper precast pile 7 and the lower precast pile 7 are completely aligned;

[0043] S6: Spot weld the steel plate at the head of the precast pile 7 to prevent the precast pile 7 from shifting due to stress after the pin 6 is taken out. Take out the pin 6 and remove the upper alignment sleeve 4 and the lower alignment sleeve 5.

[0044] Through the above technical scheme, the connection of the precast concrete piles 7 can be completed easily, accurately and conveniently, the requirements for the construction site are low, the material production and assembly operations are simple, and it can be used in a turnover manner. At the same time, it is convenient to carry with the pile driver. Multiple sets of short lever arms 2 are matched with the inner thread sleeve 3, which is suitable for the alignment and positioning of the concrete precast piles with various pile diameters, greatly improving the construction efficiency of the pile connection and alignment, and is suitable for popularization and use.

[0045] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention.
