[0002] The pipe pile foundation pit support structure uses the strength and rigidity of steel pipe piles to form a pile wall around the foundation pit to support the weight and water pressure of the surrounding soil and ensure the stability and safety of the foundation pit. Steel pipe piles generally use steel pipes with larger diameters and thicker walls. Different lengths and diameters can be used according to actual needs. During the construction process, the steel pipe piles first need to be statically pressed down by a crane to form a pile wall. The steel pipe piles need to be connected to form an overall pile wall structure.
[0003] Existing steel pipe piles are generally divided into two sections, one section is first driven into the ground, and then the other section is welded to the steel pipe pile, and then the two sections of steel pipe piles are driven into the ground. However, the two sections of steel pipe piles are easily displaced during the welding process, resulting in poor welding effect, unstable fixation of the two sections of steel pipe piles, and the steel pipe piles generally need to be continuously measured by staff during the sinking process to ensure that they sink vertically, which is time-consuming and labor-intensive, and inefficient, so there is a large room for improvement;

[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The present application embodiment discloses a pipe pile foundation pit support structure, referring to Figure 1-Figure 3, including a lower section pipe pile 1 and an upper section pipe pile 2. The materials of the lower section pipe pile 1 and the upper section pipe pile 2 are steel. The steel has high strength and is not easy to break. It can withstand strong lateral forces of the soil. A groove 3 is opened on the top of the lower section pipe pile 1. A plug-in block 4 is fixedly connected to the bottom of the upper section pipe pile 2. The plug-in block 4 is adapted to the groove 3. The lower section pipe pile 1 and the upper section pipe pile 2 are staggered and plugged through the groove 3 and the plug-in block 4. The plug-in can make the lower section pipe pile 1 and the upper section pipe pile 2 dock more accurately and stably, and the joints of the lower section pipe pile 1 and the upper section pipe pile 2 are welded. The lower pipe pile 1 and the upper pipe pile 2 are fixedly connected, and the staggered joints can make the joints of the lower pipe pile 1 and the upper pipe pile 2 not at the same elevation, increase the joint area, and make the lower pipe pile 1 and the upper pipe pile 2 more tightly connected, so as to facilitate the rapid, accurate and stable connection of the lower pipe pile 1 and the upper pipe pile 2. The outer surface of the lower pipe pile 1 is movably connected to the limit assembly, and the limit assembly includes a fixed block 5, two fixed rings 6, multiple balls 7, an inclination sensor 8 and multiple ground nails 11. The two fixed rings 6 are fixedly connected to the fixed block 5, and multiple balls 7 are fixedly connected to the fixed block 5. The beads 7 are rotatably connected to the inner side of the fixing ring 6 respectively, the fixing ring 6 is adapted to the lower pipe pile 1, the bottom of the fixing block 5 is fixedly connected with a fixing plate 10, a plurality of ground nails 11 are fixedly connected to the bottom of the fixing plate 10, and the inclination sensor 8 is fixedly connected to one side of the fixing block 5. The limit assembly is placed at the specified position, and the limit assembly is pressed downward to insert the ground nail 11 into the soil, and the fixing block 5 is adjusted to a vertical state according to the inclination sensor 8. The lower pipe pile 1 is manually lifted by a crane and inserted into the fixing ring 6. At this time, The lower pipe pile 1 is perpendicular to the fixed block 5, thereby ensuring that the lower pipe pile 1 is in a vertical state. After confirmation, the lower pipe pile 1 is sunk by the static pressure of the crane. Multiple balls 7 contact the lower pipe pile 1 and roll. The lower pipe pile 1 continues to move downward, leaving the lower pipe pile 1 a certain distance from the ground. The upper pipe pile 2 is hoisted to the top of the lower pipe pile 1 and fixedly connected with it by the crane, and then the upper pipe pile 2 and the lower pipe pile 1 are sunk by the static pressure of the crane, thereby completing the pile connection and the vertical sinking of the lower pipe pile 1 and the upper pipe pile 2, which plays a stable supporting role in the foundation pit.
[0020] Reference Figure 1 and Figure 2 The groove 3 and the plug-in block 4 are bonded by sulfur cement, which can preliminarily fix the groove 3 and the plug-in block 4, and then preliminarily fix the lower section pipe pile 1 and the upper section pipe pile 2 to prevent movement during the welding process of the lower section pipe pile 1 and the upper section pipe pile 2, so as to facilitate the welding of the lower section pipe pile 1 and the upper section pipe pile 2.
[0021] Reference Figure 3 , handles 9 are fixedly connected to both sides of the fixed block 5. After the lower section pipe pile 1 and the upper section pipe pile 2 are sunk, the two handles 9 can be manually held by hand to pull out the limit assembly and place it at the next designated pile sinking location.
[0022] Reference Figure 3The material of the ball 7 is steel with high hardness. The ball 7 is in rolling contact with the lower pipe pile 1 and the upper pipe pile 2 for a long time and is not easily damaged, thereby extending the service life of the ball 7.
[0023] Reference Figure 1 The inclination sensor 8 is electrically connected to the external controller. The inclination sensor 8 can transmit the sensed inclination angle signal of the fixed block 5 to the external controller in real time, and display it on the screen of the external controller. The staff pays attention to the screen of the external controller in real time to promptly understand whether the fixed block 5 is tilted, and makes timely adjustments to the fixed block 5 to ensure stable vertical sinking of the lower section pipe pile 1 and the upper section pipe pile 2.
[0024] The implementation principle of a pipe pile foundation pit support structure in the embodiment of the present application is as follows: by setting a lower pipe pile 1, an upper pipe pile 2 and a limit assembly, the limit assembly can be placed in a specified position, and the limit assembly can be pressed downward to allow the ground nail 11 to be inserted into the soil. The inclination sensor 8 can transmit the sensed inclination angle signal of the fixed block 5 to the external controller in real time, and display it on the screen of the external controller. The staff can pay attention to the screen of the external controller in real time to timely understand whether the fixed block 5 is tilted, and make timely adjustments to the fixed block 5, adjust the fixed block 5 to a vertical state, manually use a crane to lift the lower pipe pile 1, and insert the lower pipe pile 1 into the fixing ring 6. At this time, the lower pipe pile 1 is perpendicular to the fixed block 5, thereby ensuring that the lower pipe pile 1 is vertical. The state is confirmed to be correct, and the lower section pipe pile 1 is sunk by the static pressure of the crane. Multiple balls 7 contact the lower section pipe pile 1 and roll, and the lower section pipe pile 1 continues to move downward, leaving the lower section pipe pile 1 a certain distance from the ground, and the upper section pipe pile 2 is hoisted to the top of the lower section pipe pile 1 by the crane, and the groove 3 and the plug-in block 4 are staggered and plugged, and they are bonded by sulfur cement, and the joints of the lower section pipe pile 1 and the upper section pipe pile 2 are welded, so that the lower section pipe pile 1 and the upper section pipe pile 2 are fixedly connected, and then the upper section pipe pile 2 and the lower section pipe pile 1 are sunk by the static pressure of the crane, so as to complete the pile connection and the vertical sinking of the lower section pipe pile 1 and the upper section pipe pile 2, which plays a role in stabilizing the support of the foundation pit, and has the effect of quickly, accurately and stably connecting the lower section pipe pile 1 and the upper section pipe pile 2 and accurately and stably sinking the piles.
